-------------------- Known bugs and current work -----------------------

Add ID to more messages?

Win32 GUI: In diff mode, dragging the scrollbar doesn't update the scrollbound
windows.

Win32 GUI: Edit/Keymap and Edit/Color Scheme are empty.

GUI: Make inputdialog() work for Win16, Win32, Photon, Amiga, Mac, RiscOS.

Athena: using a fontset for menus doesn't work.  Check code for menu_fontset
marked with EXPERIMENTAL.  Perhaps use fontsets for everything?

May 6: Adjust the syntax files that didn't get updated by the maintainer, to
make them portable between 5.x and 6.0.


Main items for 6.0:
A.  Folding
	Works.
B.  UTF-8 support
	Works.
C.  Multi-line regexp patterns
	Works.
D.  Vertical window split
	Works.
E.  Virtual edit
	Works for some commands.  Still needs to be improved a lot.
F.  Sun Visual workshop (debugger) interface
	Code is included but not tested.
G.  Edit command line with Vi commands
	The command-line window works.
H.  More automatic testing
	Nothing done yet.
I.  Multi-language support
	Works.
J.  User Friendlier
	Write user manual.
	Enhance Windows install program.


E. Virtual edit:
-   Still a lot of work to do.  Test various commands.
-   "ax" in Virtual space causes a crash.
-   Add a mode where the cursor is only allowed to go one character after the
    end of the line.
-   Allow specifying it separately for Tabs and beyond end-of-line?
-   "x" on a control character doesn't do anything.
-   With cursor in virtual space, pressing "i" makes cursor jump back.
-   When doing Visual selection and including space after the end-of-line it
    is not highlighted.  It's also not included in the operation.  Should this
    be changed to include the space after the end-of-line?
-   Bugs: (Mark Waggoner)
    9.	Using "C" in virtual space moves back to the end of the current
	line to start changing rather than just starting Insert mode at the
	cursor position.
	And when the cursor is in a TAB somewhere, it also doesn't work right.
-   Leaving Insert mode when 'virtualedit' is "insert" should move the cursor
    to a valid character.
-   In Visual-block mode highlighting part of a tab is wrong.
-   Add more documentation.
-   Use vpos_T instead of fpos_T for positions that can have a coladd?
-   coladvance2() can be a bit slow.
-   Should not insert spaces for yank or filter.


F. Sun Visual Workshop patch from Gordon Prieur:
-   Displaying signs doesn't always work properly.  Should use a flag in the
    window for the sign column: it is set as soon as a sign is drawn and reset
    when editing another file.  When drawing the first sign the display isn't
    updated properly.  Force a redisplay when setting the new flag.  When not
    in the GUI or no motif, only use line highlighting (later add ASCII sign,
    like ">>" for an arrow, "!!" for a breakpoint).
-   sign mixed in with highlighting, is that what we want?
-   Check that rename from "glyph" to "sign" is correct.
-   Add ASCII signs, see patch from Mirian Lennox.
-   remove ":signs", use ":sign" without arguments to show signs
-   docs for 'balloon*' options.
-   docs for 'F' flag in 'guioptions'.
-   add stdarg.h include file in os_unix.h?
-   Add code to handle folding.


H. More automatic testing:
-   Check all commands for:
    - Handling folds (moving vertically, updating folds)
    - Vertical splits (displaying with w_wincol, updating w_width and other
      windows)
    - Use with virtualedit.
    - Working with filler lines.
    - Use of multi-byte characters.
    - Make test for multi-line regexp and ":s".


J. User Friendlier
9   Printing:
    -	On Win32, use conversion to HTML and "rundll" (Dan Sharp)  At least
	mention this in the text.  Or use ShellExecute("print").
    -	Make conversion to html faster (Write it in C).
    -	Add "page width" to wrap long lines.
    -	On Win32, use GDI functions to print directly
    -	On Unix convert to PostScript.
    -	Use some dialog box to do the obvious settings (paper size, printer
	name, portrait/landscane, etc).
9   Make Windows install program better:
    - Add an icon on the Desktop, if the user wants this.
    - Add Vim to the Start/Programs menu if the user wants this.
    - Detect the OLE version and register it.
    - Allow adding a "edit with Vim" entry even when Vim already is in $PATH.
    - Create $VIM/vimfiles/[plugin|ftplugin|doc] directories, so that plugins
      can really be dropped-in.
    - Delete the vim.bat and gvim.bat files.
    - Also create an evim.bat and vimdiff.bat file.  How about view.bat?
    - Delete a whole tree of Vim files.


Messages:
-   Need to hit return after selecting entry for ":ts".
-   Remember message line for redraw.  Use instead of keep_msg.  Integrate the
    command line in update_screen().
-   Check: ":cn" message is sometimes cleared.  Should be truncated.


Various recent:
-   In ":ptag" preview window highlight the tag.  Use the new regexp items.
9   Crash when creating XIC without a fontset. (Diamond)  Don't include the
    XNFontSet then?  Check if gui.normal_font is a fontset?
8   Syntax error: Can't reproduce it now.  Looked like an "O" command caused a
    line to be redrawn that was moved down (since a line was inserted), found
    a start-of-comment error on "/*", thus it was using a cached state that
    the comment already started in this line (what would be true for this line
    before the new line was inserted)
9   These places need to be fixed for EBCDIC:
    -   AppendToRedobuffLit().
    -   stuffescaped().
    -   set_last_insert()
8   gui_w16.c and gui_w32.c still have much code in common.  Move this to
    gui_w48.c.
9   What happens with :execute "normal a\<Up>\200\<Esc>"?
    How to distinguish a special key from a 0x80 byte?  CSI too.
9   This pattern in syntax/java.vim causes a recursive call of regmatch():
	syn match   javaStringError      +"\([^"\\]\|\\.\)*$+
    A long line with a " in it can cause a crash when it runs out of stack
    space (on non-Unix systems).  How can we catch this?
8   Implement ":tearoff" for other systems than Win32 GUI.
8   ":let @" = "val" should not have side effects for other registers (after
    "ayy). (Raul Acevedo)
    ""yy should probably not change the last used register from "ayy.
9   Support ACLs on more systems.
-   GUI: Implement ":popup" for other systems than Windows.
-   GUI: <C--> cannot be mapped.  Should be possible to recognize this as a
    normal "-" with the Ctrl modifier.
9   GTK GUI with Gnome: When $DISPLAY is wrong, ":gui" unexpectedly exits.
    Without Gnome it does work.
    Not all Gnome arguments get to gnome_init().
8   Add "display" argument to many items in syntax files, to speed up parsing.
-   update $VIMRUNTIME/optwin for new options.
-   When using the file browser in GTK the absolute file name is used.  Should
    try to simplify it. (Lohner)
-   Make it possible to set 'browsedir' to a directory name, which is always
    used.
-   When checking if a file exists on Unix, use lstat(), otherwise a symlink
    will not be found.  Go throught the code to check for this.
-   Check all use of islower()/isupper() for negative value (special key).
-   Include pty check for Lynx: ~/vim/patches/hahn.pty .
-   Remove "\" shown in complete/wildmenu.
    Bug: <C-O>:emenu in Insert mode inserts the command.
-   When accidentally hitting Shift-R instead of Ctrl-R, further Ctrl-R is not
    possible, also when typing <Esc> immediately. (Grahn)
-   Include flipcase patch: ~/vim/patches/wall.flipcase2 ?  Make it work for
    multi-byte characters.
8   Use $install_prefix? (Cabric)
8   Test if it possible for a skip pattern to include "\n", so that it can
    skip over newlines for a "oneline" region.
-   Check use of multi-line regexp in syntax highlighting.
-   When starting GUI with invalid $DISPLAY, the hit-enter prompt is always in
    line 2, while the "cannot open display" is somewhere else.
-   When swap file message sees that date of file is newer as date of swap
    file, add message "more recent than swap file".
-   "ls -1 * | xargs vim" works a bit but not well.  Should use stderr for all
    term I/O.
9   ":cwindow!" always open quickfix window, ":cwindow" only open it if there
    are recognized errors.  ":cclose" to close quickfix window?
8   For ":silent !cmd":
    ":silent write" still writes a message.
    ":silent s//" still writes a message.
    Highlight test should be silent.  ":silent highlight" doesn't produce the
    same redirected text.  Make it do the same.
    How to use ":silent" for a search command?  ":silent /pat" uses ":/pat".
	:silent exe "normal /path\<CR>"
    Run the external command silently, don't give the hit-enter prompt.
    Remove how it's done for Risc OS with ":!~cmd", see do_shell().
    Don't redraw the screen, make a note in the docs that CTRL-L should be
    used if the command has any output.
    -> pass SHELL_FILTER to call_shell?
    -> ":silent!" also stops error messages.
    -> ":silent menu" creates menu that doesn't echo its command.
    -> ":silent /pattern" doesn't complain when it's not found
    -> ":silent :s/pat//" doesn't complain when it's not found and doesn't
		report number of substitutions.
    -> ":silent map": add flag to mapping, increment "silence" when executing
       it, append a command to decrement "silence"; reset silence when
       aborting a mapping).
       Or use ":map <silent>"?
    -> ":silent unmap" shouldn't complain about a non-existing mapping.
    Still do the messages for ":redir"?
    -> ":silent redir": Remember the last message, print it if waiting for a
       key (otherwise the hit-enter prompt could be missed).
    -> Win32 GUI: Make ":silent !ls" work, avoid "hit any key to continue" in
       DOS console used to execute external commands.  Pass a flag to
       vimrun.exe.
    Ideas in ~/vim/patches/wall.noredir.tgz (Stephen P. Wall).
-   Make syntax keyword table configurable.  Set number of bits used with
    ":syn clear [hashbits]", so that we don't need to reallocate the table.
    minimal 4 bits, maximal 16. (Campbell)
-   Check all places where buf_write() is called if it takes care of "buf"
    becoming invalid because of autocommands.  Also callers of
    buf_check_timestamp().
-   Add "gG": like what "gj" is to "j": go to the N'th window line.
-   xterm sends <Esc>O5F for <C-End>
-   Support ":browse edit" in console, using explorer.vim?
-   When displaying a space with only foreground highlighting, it's the same
    as a space without attributes.  Avoid displaying spaces for the "~" lines
    when starting up in a color terminal.
-   Windows NT: writing to aux.* makes Vim hang. (Acevedo)
-   Problem with cscope jumping to the wrong position? (Medley)
    Selecting item 5 jumps to item 4. (Andrej Borsenkow)
-   ":abbr b byte", append "b " to an existing word still expands to "byte".
    This is Vi compatible, but can we avoid it anyway?
-   Add a watchpoint in the debug mode: An expression that breaks execution
    when evaluating to non-zero.
8   When running in a console and $DISPLAY is set a connection to the X server
    is made (unless 'clipboard' tells not to).  Quitting the X server then
    kills Vim.  How to detect a broken connection to the X server when running
    in a console?  Catching WM_SAVE_YOURSELF doesn't seem to work.


Considered for release 6.0:
8   Use configure to set absolute paths in tools scripts when installing.
8   Add a command to jump to a certain kind of tag.  Allow the user to specify
    values for the optional fields.  E.g., ":tag size type=m".
8   Add file locking.  Lock a file when starting to edit it with flock() or
    fcntl().  This patch has advisory file locking while reading/writing the
    file: ~/vim/patches/kahn_file_locking .
-   When $CFLAGS is set, don't change it in configure. (Griffis)
    Give a warning that CFLAGS from the environment is being used.
8   Windows (and others): When using the scrollbar to scroll, don't move the
    cursor position.  When moving the cursor scroll to the cursor position.
8   How to create the gvim.exe that is distributed?  Make_gvc.mak is standard,
    but Make_mvc.mak supports gettext, iconv, perl, etc.
9   It is possible to create the same swap file twice, when there is latency
    in the system (and 'directory' is ~/tmp). (Soulier)
    Create the swap file as soon as its name is chosen, when mf_fname is set.
    Delete it before changing mf_fname/mf_ffname.
8   Add command like ":normal" that accepts <Key> notation like ":map".
8   Make clipboard work for Dos32 version. (Negri)
8   ">>" with 'softtabstop' set should work like 'tabstop' is set to
    'softtabstop'. (Zivkov)  But what about when there is a string?
9   Install vim32x32.xpm in /usr/local/share/icons/ or ~/.kde/share/icons/ for
    using it with KDE.
7   Add ModeMsgVisual, ModeMsgInsert, etc. so that each mode message can be
    highlighted differently.
-   For files found with 'include': handle "*" in included name, for Java.

---------------------- bugs ---------------------------

Vi incompatibility:
8   Docs for ":s&" are not correct.  What is it supposed to do?  When exactly
    are flags re-used?  What is a Vim extension?
8   With undo/redo only marks in the changed lines should be changed.  Other
    marks should be kept.  Vi keeps each mark at the same text, even when it
    is deleted or restored. (Webb)
    Also: A mark is lost after: make change, undo, redo and undo.
    Example: "{d''" then "u" then "d''": deletes an extra line, because the ''
    position is one line down. (Veselinovic)
8   When using ":s" to split a line, marks are moved to the next line. (Geddes)
8   When using ":n" ":rew", the prev. context mark is in the same place as the
    cursor, not on the first line.
8   "zt" should scroll one screen forward and put the cursor in the first
    line.
8   ":z#" should list lines with line numbers. (Bob Farmer)
8   text is put in register 1 when using "c" and "d" with a motion character:
    <control-A>   %   (   ) `<character>   /   ?   N n	 {   }
    (from Nvi manual).
8   When stdin is not a tty, and Vim reads commands from it, an error should
    make Vim exit.
8   Unix Vim (not gvim): Typing CTRL-C in Ex mode should finish the line
    (currently you can continue typing, but it's truncated later anyway).
8   When loading a file in the .exrc, Vi loads the argument anyway.  Vim skips
    loading the argument if there is a file already. When no file argument
    given, Vi starts with an empty buffer, Vim keeps the loaded file. (Bearded)
8   In Insert mode, when using <BS> or <Del>, don't wipe out the text, but
    only move back the cursor.	Behaves like '$' in 'cpoptions'.  Use a flag
    in 'cpoptions' to switch this on/off.
8   When editing a file which is a symbolic link, Vim opens another symbolic
    link on the same file under the name of the first one.  Adjust the file
    name in the buffer to the last one used?  Use several file names in one
    buffer???
7   The ":map" command output overwrites the command.  Perhaps it should keep
    the ":map" when it's used without arguments?
7   When interrupting reading a file, Vi considers the buffer modified.  Add a
    'cpoptions' flag for this (we don't want it modified always to be able to
    do ":q")?
7   CTRL-L is not the end of a section?  It is for Posix!  Make it an option.
7   Implement 'prompt' option.	Init to off when stdin is not a tty.
7   CTRL-T in Insert mode inserts 'shiftwidth' of spaces at the cursor.  Add a
    flag in 'cpoptions' for this.
7   Add a way to send an email for a crashed edit session.  Create a file when
    making changes (containing name of the swap file), delete it when writing
    the file.  Supply a program that can check for crashed sessions (either
    all, for a system startup, or for one user, for in a .login file).
7   Vi doesn't do autoindenting when input is not from a tty (in Ex mode).
7   "z3<CR>" should still use the whole window, but only redisplay 3 lines.
7   ":tag xx" should move the cursor to the first non-blank.  Or should it go
    to the match with the tag?	Option?
7   Implement 'autoprint'/'ap' option.
7   Add flag in 'cpoptions' that makes <BS> after a count work like <Del>
    (Sayre).
7   Add flag in 'cpoptions' that makes operator (yank, filter) not move the
    cursor, at least when canceled. (default vi compatible).
7   Make "5dd" on last-but-one-line not delete anything (Vi compatible).
    Add flag in 'cpoptions' for this.  When not present, "2dd" in the last
    line should delete the last line.
7   This Vi-trick doesn't work: "Q" to go to Ex mode, then "g/pattern/visual".
    In Vi you can edit in visual mode, and when doing "Q" you jump to the next
    match.  Nvi can do it too.
7   Support '\' for line continuation in Ex mode for these commands: (Luebking)
	g/./a\		    g/pattern1/ s/pattern2/rep1\\
	line 1\		    line 2\\
	line 2\		    line 3\\
	.		    line4/
6   ":e /tmp/$tty" doesn't work.  ":e $uid" does.  Is $tty not set because of
    the way the shell is started?
6   Vi compatibility (optional): make "ia<CR><ESC>10." do the same strange
    thing.  (only repeat insert for the first line).
8   When "cm" termcap entry is missing, starting gvim shouldn't complain about
    it. (Lohner)  Try out with "vt100" entry (cm replaced with cX).

GTK+ GUI known bugs:
-   GTK with Gnome gives error message:
	Gdk-WARNING **: locale not supported by C library
    Looks like this can't be avoided.
9   When logging out from KDE, vim is not told to save its files.  Catching
    the WM_SAVE_YOURSELF event doesn't work.
8   For some fonts characters are drawn in the line above.  Include fix
    ~/vim/patches/dalecki-5.6 . (Marcin Dalecki)
9   When selecting a font from the font selector with an embedded space it
    cannot be found. (Tsirkin)
8   When a font is not fixed width, the message "not fixed-width" disappears
    immediately. (Tsirkin)
    Add some code to handle proportional fonts?  Need to draw each character
    separately (like xterm).  Also for when a double-width font is not exactly
    double-width. (Maeda)
8   Move gtk_main_quit() calls from call to add_to_input_buf() to inside the
    function?
9   Can't paste a Visual selection from GTK-gvim to vim in xterm when it is
    longer than 4000 characters.  Works OK from gvim to gvim and vim to vim.
    This is a GTK problem.
9   With the guifont "-*-clean-medium-r-*-*-8-*-*-*-*-80-*" bold characters
    are drawn wrong.  Try on C source code.  The bold font is wider than the
    medium font.  Check bold font cellsize and use bold font trick if it's
    wrong?
8   Font "7x14" has a bold version "7x14bold".  Try to find the bold font by
    appending "bold" when there are not 14 dashes.
8   When using "gvim -geom 40x30" or setting 'columns' in .gvimrc or with a
    GUIEnter autocommand, the width is still set to fit the toolbar.  Also
    happens when changing the font.  How to avoid that the toolbar specifies
    the minimal window width?


Win32 GUI known bugs:
-   Check libcall() and libcallnr() for Win32.  No crash when function returns
    1 or -1?
8   Win32 GUI: With maximized window, ":set go-=r" doesn't use the space that
    comes available. (Poucet)  It works OK on Win 98 but doesn't work on Win
    NT 4.0.  Leaves a grey area where the scrollbar was.  ":set go+=r" also
    doesn't work properly.
8   The dialog boxes don't have an indication of which button is the default.
    E.g., the dialog for a changed file. (Webb)
8   When Vim is minimized and when maximizing it a file-changed dialog pops
    up, Vim isn't maximized.  It should be done before the dialog, so that it
    appears in the right position. (Webb)
9   Check dosinst.c with Vim in "Program Files" (long filename).  Does it use
    the short filename instead and does the path compare work?
8   When activating window with mouse click, don't move cursor to mouse click.
    Catch WM_MOUSEACTIVATE. (Luevelsmeyer)
9   Clipboard doesn't always work as it should:
    - Selecting text while editing a command-line has an implied copy to the
      clipboard.  Remove this, and add a command character to copy/cut/delete
      the selected text (used in the popup menu).
    - When selecting at the more-prompt or hit-enter-prompt right mouse
      button doesn't give popup menu.  Also has an implied copy to the
      clipboard.  Use the popup menu "Copy" entry for that.
9   When there are more than 32767 lines, the scrollbar has a roundoff error.
    Clicking the up or down error scrolls two lines or more.  Looks like there
    is an extra event that reports the new position of the scrollbar.
9   When file modified outside of Vim and Vim gets focus, redraw is wrong.
    Put focus event in input buffer and let generic Vim code handle it.
8   Make new version of VisVim.dll which includes the patch from Cordell.
8   When 'grepprg' doesn't execute, the error only flashes by, the
    user can hardly see what is wrong. (Moore)
    Could use vimrun with an "-nowait" argument to only wait when an error
    occurs, but "command.com" doesn't return an error code.
8   When the 'shell' cannot be executed, should give an appropriate error msg.
8   MessageBox used for error messages can be too big.	There is no way to
    scroll it, or even hit the OK button (but you can hit return).
7   Add an option to add one pixel column to the character width?  Lucida
    Console italic is wider than the normal font ("d" overlaps with next char).
7   At the hit-enter prompt scrolling now no longer works.  Need to use the
    keyboard to get around this.  Pretend <CR> was hit when the users tries to
    scroll?
7   'mousefocus' is disabled until the next mouse click, when trying to exit
    by hitting the X in the title bar. (Webb)
7   Scrollbar width doesn't change when selecting other windows appearance.
    Also background color of Toolbar and rectangle below vert. scrollbar.
7   "!start /min cmd" should run in a minimized window, instead of using
    "/min" as the command name. (Rogall)
6   Drawing text transparantly doesn't seem to work (when drawing part cursor).
8   CTRL key doesn't always work in combination with ALT key.  It does work
    for function keys, not for alphabetic characters.
8   CTRL-@ doesn't work.  Don't even get a message for it?
8   CTRL-- doesn't work for AZERTY, because it's CTRL-[ for QWERTY.  How do we
    know which keyboard is being used?
8   When using ":se guifont=Courier_New" bold chars leave pixels behind, in
    front of a character, after a TAB.  (McRae)
7   When scrolling, and a background color is dithered, the dither pattern
    doesn't always join correctly between the scolled area and the new drawn
    area (Koloseike).
7   File/Print uses notepad, which puts the name of the temp file on top of
    each page.  How do we get the actual file name there?
    Alternative: use the PrintFile utility (freeware).
    Alternative: use prfile32 (Aaron)
8   install.exe, vimrun.exe and ctags are not build from Gvim_vc.mak.  When
    added, check that this works from the command line and from the IDE.
8   When dropping a shortcut on gvim (.lnk file) should edit the target, not
    the shortcut itself.
9   OleVim doesn't send <C-\><C-N>, which causes trouble if Vim is in Insert
    mode. (Thakkar)
9   Replace SendToVim and OpenWithVim with C++ versions? (Rafal Dibrowa)
8   Tear-off menu causes a crash when it contains many items (>100).
    (Pedro Gomes)  Probably because DLG_ALLOC_SIZE is a fixed number.


Athena GUI:
9   Use one of the Syntax menu items.  Then ":aunmenu Syntax", Vim crashes.
    Also crashes when using Buffers.Refresh.
9   When using ":unmenu" in menu item, the reversing of menu items is wrong.
    Happens with Syntax/manual.	Problem with not removing the reversed text
    when destroying the menu item?  For Rochholz Vim crashes.
9   Because destroying a menu can cause a crash, it is not destroyed but
    unmanaged.  The destoyed Widgets are remembered, this list is never
    cleaned up.
9   When closing the confirm() dialog, Vim exits.
9   When using "menu a.b.c.d lll", the "b" submenu does not disappear.
9   When dragging the scrollbar thum very fast, focus is only obtained in
    scrollbar itself.
8   When "j" or "k" repeated quickly, display is messed up (Lauther).
8   Has extra stripes here and there. (Zeitlin).
    When dragging last status line with the mouse, small black lines appear in
    the command line pseudo-scrollbar (only when status line moved quickly).
7   The file selector is not resizable.  With a big font it is difficult to
    read long file names. (Schroeder)
7   The file selector's scrollbar colors are not set after doing a
    ":hi Scrollbar guifg=color". (David Harrison)


Motif GUI:
8   Motif GUI: draws in right border of window, scrolling leaves pixels
    behind.  Scroll two more pixels?  Or make window two pixels wider?
9   When starting GUI with ":gui" while 'writedel' is non-zero, escape
    sequences are split up.  Motif version crashes.
8   When changing the color of the toolbar with ":hi toolbar", the pixmaps are
    not updated.  Need to destroy them and allocate with the new colors.
8   Popup menu ordering is wrong.
8   Dialog: Pointer should be moved to the default button.  Accelerators don't
    work yet.
8   Lesstif 0.89.4: Tearing-off a menu sometimes gives a "Restoring focus to
    NULL widget!" error.  Probably a Lesstif problem.
8   Lesstif: When deleting a menu that's torn off, the torn off menu becomes
    very small instead of disappearing.  When closing it, Vim crashes.
    (Phillipps)


GUI:
9   When using a very small font, 'columns' can be very big.  Pass mouse
    events with 16 bits.
9   On Solaris, creating the popup menu causes the right mouse button no
    longer to work for extending the selection. (Halevy)
9   When running an external program, it can't always be killed with CTRL-C.
    e.g. on Solaris 5.5, when using "K" (Keech).  Other 'guipty' problems on
    Solaris 2.6. (Marley)
9   On Solaris: Using a "-geometry" argument, bigger than the window where Vim
    is started from, causes empty lines below the cmdline. (raf)
8   X11 GUI: When menu is disabled by excluding 'm' from 'guioptions', ALT key
    should not be used to trigger a menu (like the Win32 version).
8   When setting 'langmenu', it should be effective immediately.  Store both
    the English and the translated text in the menu structure.  Re-generate
    the translation when 'langmenu' has changed.
8   Basic flaw in the GUI code: NextScreen is updated before calling
    gui_write(), but the GUI code relies on NextScreen to represent the state
    of where it is processing the output.
    Need better separation of Vim core and GUI code.
8   When fontset support is enabled, setting 'guifont' to a single font
    doesn't work.
8   Menu priority for sub-menus for: Athena, Amiga, Mac, VMS, BeOS.
8   Add menu separators for Amiga, Mac, RISCOS.
8   Add way to specify the file filter for the browse dialog.  At least for
    browse().
8   Add dialog for search/replace to other GUIs?  Tk has something for this,
    use that code?  Or use console dialog.
8   When selecting a font with the font dialog and the font is invalid, the
    error message disappears too quick.
8   gui_check_colors() is not called at the right moment.  Do it much later,
    to avoid problems.
8   gui_update_cursor() is called for a cursor shape change, even when there
    are mappings to be processed.  Only do something when going to wait for
    input.  Or maybe every 100 ms?
8   X11: When the window size is reduced to fit on screen, there are blank
    lines below the text and bottom scrollbar.  "gvim -geometry 80x78+0+0".
    When the "+0+0" is omitted it works.
8   When the character cell of some fonts is different (ascent/descent), the
    cursor leaves an underline behind (Hiebert).
8   When starting an external command, and 'guipty' set, BS and DEL are mixed
    up.  Set erase character somehow?
8   A dead circumflex followed by a space should give the '^' character
    (Rommel).  Look how xterm does this.
    Also: Bednar has some code for dead key handling.
    Also: Nedit 5.0.2 with USE_XMIM does it right. (Gaya)
8   The compose key doesn't work properly (Cepas).  Both for Win32 and X11.
7   The compiled-in highlight defaults allocate colors, which will never be
    freed.  Move them to a startup script?  Only use bold and underline for
    the compiled-in defaults.
7   The cursor in an inactive window should be hollow.  Currently it's not
    visible.
8   With wrapping lines, clicking below the scrollbar thumb moves more than a
    screenfull of lines.  Adjust the thumb size when lines wrap.
7   GUI on Solaris 2.5.1, using /usr/dt/..: When gvim starts, cursor is
    hollow, after window lowered/raised it's OK. (Godfrey)
7   When starting GUI with ":gui", and window is made smaller because it
    doesn't fit on the screen, there is an extra redraw.
8   When setting font with .Xdefaults, there is an extra empty line at the
    bottom, which disappears when using ":set guifont=<Tab>". (Chadzelek)
8   When font shape changes, but not the size, doing ":set font=" does not
    redraw the screen with the new font.  Also for Win32.
    When the size changes, on Solaris 2.5 there isn't a redraw for the
    remaining part of the window (Phillipps).
-   Flashes really badly in certain cases when running remotely from a Sun.


MSDOS/DJGPP:
8   Win32: Opening a file dir\&file doesn't work.  Also \^.  Do we care?
8   DJGPP: "cd c:" doesn't work.  Works OK in 16-bit version.  mch_getperm()
    returns -1 for "c:".
9   The 16 bit version runs out of memory in test 31.
9   DOS: Make CTRL-Fx and ALT-Fx work.
    CTRL-F1 = CE-5E, CTRL-F2 = CE-5F, .., CTRL-F10 = CE-67
    ALT-F1 = CE-68, ALT-F2 = CE-69, .., ALT-F10 = CE-71
    Shifted cursor keys produce same codes as unshifted keys.  Use bioskey(2)
    to get modifier mask for <S-C-M-Fx>.
    Use CSI codes to insert modifier mask in input stream?  Make this work
    like in the GUI, but do handle a typed CSI.
    Mapping things like <M-A> doesn't work, because it generates an extended
    key code.  Use a translation table?
9   Can't read an opened swap file when the "share" command has not been used.
    At least ignore the swap files that Vim has opened itself.
8   setlocale() is bogus.
8   Vim busy waits for new characters or mouse clicks.	Should put in some
    sort of sleep, to avoid eating 50% of the CPU time.  Test on an unpatched
    Windows 95 system!
8   DJGPP: when shell is bash, make fails. (Donahoe)
7   Hitting CTRL-P twice quickly (e.g. in keyword completion) on a 8088
    machine, starts printer echo! (John Mullin).
7   MSDOS 16 bit version can't work with COMSPEC that has an argument, e.g.:
    COMSPEC=C:\WINDOWS\COMMAND.COM /E:4096    (Bradley)
    Caused by BCC system() function (Borland "make" has the same problem).
8   Makefile.bor can't compile xxd and ctags without editing the makefiles.
    Create a Makefile.bor for xxd and ctags.
8   Check if with DJGPP 2.01 the problem of a path starting with a backslash is
    still present.
8   Mouse: handle left&right button pressed as middle button pressed.  Add
    modifier keys shift, ctrl and alt.
7   When too many files are open (depends on FILES), strange things happen.
    The Dos16 version runs out of memory, in the Dos32 version "!ls" causes a
    crash.  Another symptom: .swp files are not deleted, existing files are
    "[New file]".
7   DJGPP version doesn't work with graphics display mode.  Switch to a mode
    that is supported?
8   DJGPP: ":mode" doesn't work for many modes.  Disable them.


MSDOS, OS/2 and Win32:
8   OS/2: Add backtick expansion.  Undefine NO_EXPANDPATH and use
    gen_expand_wildcards().
8   OS/2: Add clipboard support?  See example clipbrd.exe from Alexander
    Wagner.
8   OS/2: Add Extended Attributes support and define HAVE_ACL.
8   Win32 console: <M-Up> and <M-Down> don't work. (Geddes)  We don't have
    special keys for these.  Should use modifier + key.
8   Win32 console: caps-lock makes non-alpha keys work like with shift.
    Should work like in the GUI version.
8   Environment variables in DOS are not case sensitive.  Make a define for
    STRCMP_ENV(), and use it when comparing environment var names.
8   Setting 'shellslash' has no immediate effect.  Change all file names when
    it is set/reset?  Or only use it when actually executing a shell command?
8   When editing a file on a Samba server, case might matter.  ":e file"
    followed by ":e FILE" will edit "file" again, even though "FILE" might be
    another one.  Set last used name in buflist_new()?  Fix do_ecmd(), etc.


Windows 95:
8   Editing a file by it's short file name and writing it, makes the long file
    name disappear.  Use Unix method for making a backup file?	Better: make
    the way the backup file is made (copy or rename) an option, not a #define
    (also needed for OS/2, the icon goes to the backup file).
    Use FindFirstFile()->cAlternateFileName in fname_case() (George).
8   Doing wildcard expansion, will match the short filename, but result in the
    long filename (both DJGPP and Win32).


Win32 console:
9   When editing a file by its short file name, it should be expanded into its
    long file name, to avoid problems like these: (Mccollister)
     1) Create a file called ".bashrc" using some other editor.
     2) Drag that file onto a shortcut or the actual executable.
     3) Note that the file name is something like BASHRC~1
     4) Go to File->Save As menu item and type ".bashrc" as the file name.
     5) Press "Yes" to indicate that I want to overwrite the file.
     6) Note that the message "File exists (use ! to override)" is displayed
	and the file is not saved.
    Use FindFirstFile() to expand a file name and directory in the path to its
    long name.
8   Also implement 'conskey' option for the Win32 console version?  Look at
    how Xvi does console I/O under Windows NT.
7   Re-install the use of $TERM and support the use of different terminals,
    besides the console.
8   Use of <altgr> modifier doesn't work?  5.3 was OK. (Garcia-Suarez/Guckes)
9   Mapping <C-S-Tab> doesn't work correctly.
9   tmpnam() uses file in root of file system: "\asdf".  That doesn't work on
    a Netware network drive.  Use same function as for Win32 GUI?
8   In os_win32.h, HAVE_STRICMP and HAVE_STRNICMP are defined only if __GNUC__
    is not defined.  Shouldn't that be the other way around?
9   When using libcall() for a function that returns an invalid pointer, Vim
    crashes.  Check for a bad pointer with isBadReadPtr(). (Zeitlin)
    Doesn't appear to work really, at least check for "1".


Amiga:
9   In mch_expandpath() a "*" is to be expanded, but "\*" isn't.  Remove
    backslashes in result.
8   Executing a shell, only one option for 'shell' is separated.  Should do
    all options, using white space separation.


Macintosh:
8   Define vim_mkdir() for Macintosh.
9   Explorer.vim isn't working properly.
9   When DiskLock is running, using a swap file causes a crash.  Appears to be
    a problem with writing a file that starts with a dot. (Giacalone)
9   On G3 Mac, OS version 8, control strip causes characters messed up when
    scrolling (CTRL-L cleans it up). (Benji Fisher)
9   On G3 Mac, OS version 8, variable-speed scrolling doesn't work, after two
    seconds of scrolling the screen freezes. (Benji Fisher)
    scrolling (CTRL-L cleans it up). (Benji Fisher)
9   In mac_expandpath() check that handling of backslashes is done properly.
9   Executable is called "vimPPC" instead of "gvim"? (Amerige)
8   Standard Mac buttons and shortcuts are missing.  No close button.
    (Amerige)
8   An invocation of gvim hands over control to an existing gvim. (Amerige)
8   Handling of non-fixed width fonts is wrong. (Amerige)
8   StatusLine and StatusLineNC highlighting isn't right. (Amerige)


VMS:
8   VMS: Inserts <NL> every 8291 bytes when writing. (Howie)  4.5 didn't have
    this problem.  It's caused by the write() function, need to write() every
    line separately.  It seems read() also returns a single line.  Switch I/O
    to binary mode somehow?
7   Lots of code in common with os_unix.c, but many fixes are missing.  Move
    shared code to a common file?  Use one file with #ifdefs?


"Small" problems:
8   For a "/*" "**" "*/" comment the end isn't aligned properly.
    Using "==" the middle isn't aligned as 'comments' indicates.
	:set comments=sr:/*,mb:**,ex:*/,://
8   A nested include file should also be found relative to the file that
    includes it.  "lev1/foo.h" includes "lev2/bar.h" which is
    "lev1/lev2/bar.h".  Should pass current file name on from
    find_pattern_in_path() to get_file_name_in_path(). (Angus Mackay)
9   When jumping to a tag, the search pattern is put in the history.  When
    'magic' is on, the pattern may not work.  Translate the pattern depending
    on p_magic when putting it in the history?  Alternative: Store value of
    'magic' in history.  (Margo)
9   Viminfo file becomes corrupt when editing a file with a <NL> in the name.
    (file marks, buffer list, history of marks) (Alexander N.Benner, Wichert
    Akkerman, Weisselberg)
    Also problems with buffer menu.
9   optwin.vim: Restoring a mapping for <Space> or <CR> is not correct for
    ":noremap".  Add "mapcmd({string}, {mode})?  Use code from ":mkexrc".
9   When starting gvim in an xterm, Vim sends t_vi and t_ve to the terminal
    (cursor invisible/visible).  Should not happen.
9   incsearch is incorrect for "/that/<Return>/this/;//" (last search pattern
    isn't updated).
9   term_console is used before it is set (msdos, Amiga).
9   Get out-of-memory for ":g/^/,$s//@/" on 1000 lines, this is not handled
    correctly.  Get many error messages while redrawing the screen, which
    cause another redraw, etc.
9   When first editing file "test", which is symlink to "test2", and then
    editing "test2", you end up editing buffer "test" again.  Change the name
    of the buffer to the actual file, instead of using the name of the
    symlink?
8   [<C-I> doesn't work when '*' is in 'iskeyword'.  find_pattern_in_path()
    must escape special characters in the pattern.
8   Vim can overwrite a read-only file with ":w!".  ":w" can't overwrite an
    existing file, "w!" can, but perhaps not a read-only file?  Then use
    ":w!!" for that.
    Or ask for permission to overwrite it (if file can be made writable) and
    restore file to readonly afterwards.
8   Buffers menu, when torn-off, disappears when being refreshed.
8   Buffers menu looks bad with very long file names.  Make long names shorter
    by putting "..." in the middle. (Ron Aaron)
8   Is calling msg_start() in main() really needed?  Any printed message
    should include it already.
8   When in Insert mode with 'scrolloff' set, inserting text at the end of the
    file, "!" lines will stay there while they could be used. (Park)
7   When compiled with "xterm_clipboard", startup can be slower and might get
    error message for invalid $DISPLAY.  Try connecting to the X server in the
    background (forked), so that Vim starts up quicker?
8   For xterm need to open a connection to the X server to get the window
    title, which can be slow.  Can also get the title with "<Esc>[21t", no
    need to use X11 calls.  This returns "<Esc>]l{title}<Esc>\".
8   Add term entries for function keys on xterm with alt and ctrl (new in pl
    94).  E.g., Control adds ";5" in "<Esc>[20;5~".  Find a generic way to
    prepend a modifier in console mode, to avoid having to specify each
    individual modified key.
8   When the builtin xterm termcap contains codes that are not wanted, need a
    way to avoid using the builtin termcap.
8   '[ and '] should be set to start/end of line when using a linewise operator
    (e.g., ":w").
8   CTRL-A can't handle big "long" numbers, they become negative.  Check for
    "-" character, if not present, use unsigned long.
8   Make it possible to disable the special meaning of "#" in the first column
    for ">>".
8   Add suspending with CTRL-Z at the "more" prompt, and when executing a long
    script in do_cmdline().
8   When using 'hidden', many swap files will be open.  When Vim runs into the
    maximum number of open files, error messages will appear.  Detect that
    this problem is present, and close any hidden files that don't have
    changes.
8   With 'viminfo' set such that the ".viminfo" file is written on a FAT
    filesystem, an illegal file name may be created: ".vim".
8   For each buffer that is opened, the viminfo file is opened and read to
    check for file marks.  This can be slow.
7   "dd" on the last line of the file, causes the last but one line to be
    redrawn.  Should not be necessary.
7   Using "gqj" near the last line of the window, makes the window scroll up,
    even though this isn't necessary.
8   Should be able to compile Vim in another directory, with $(srcdir) set to
    where the sources are. Add $(srcdir) in the Makefile in a lot of places.
    (Netherton)
8   Perl adds arguments to the compiler.  Check that compiling a program still
    works after that, otherwise following configure checks will fail.
7   In xterm, recognize both vt100 and vt220 cursor keys.  Change
    add_termcode() to not remove an existing entry for a name, when it's
    needed.
    Recognize <C-Left> and <C-Right> in new xterm.
    Need a generic solution to recognize different codes for the same key.
8   Core dump within signal function: gdb doesn't show stack backtrace!  Option
    to skip catch_signals()?
8   Pasting with the mouse in Replace mode inserts the text, instead of
    overwriting, when it is more than one line.  Same for using <C-R>.
7   When using search history, the trailing '/' or '?' needs to be changed
    depending on the search command.  When there was no '/' or '?', add one, so
    flags can be added easily?
7   CTRL-F at the end of the file, when 'so' is set, redraws twice.  When the
    window is small (< 2 * 'so') it behaves differently.
9   CTRL-E and CTRL-Y don't work in small window when 'so' is 4 and lines are
    wrapping (Acevedo/in.226).  E.g., when using CTRL-E, window height 7,
    window might actually scroll down when last line of buffer is displayed.
    --> Remember if the previous command was "cursor follows screen" or
    "screen follow cursor" and use this in cursupdate().
9   Text is scrolled up and down: (acevedo)
     - set scrolloff to something >1 (i always use "set so=4")
     - set the win. hegiht to scrolloff + 1  (i'd do ^W5_)
     - load a file with scrolloff + 2 lines
     - put the cursor in line scrolloff +1  (5G)
     - if you move the cursor along the line (h, l, insert text, etc)
     the text is crolled with each keystroke (once up, once down,...)
     sometimes with <Esc> the text is scrolled up and down without stop!!!!
7   tilde_replace() can only handle "~/", should also do "~user/".
    Get the list of home directories (from /etc/passwd?  Use getpwent()) and
    use some clever algorithm to match a path with that.  Find common strings
    in the list?
8   Add 'o' flag to 'mouse'?
8   When dragging status line with mouse, sometimes a jump when first clicking
    on the status line (caused by 'winheight').  Select window on button up,
    instead of on button down.
7   There are often a few <CR> on a row sent to the screen, should not be
    necessary.
8   When performing incremental search, should abort searching as soon as a
    character is typed.
8   Make CTRL-C on Unix generate a signal, avoid using select() to check for a
    CTRL-C (it's slow).  Allow using CTRL-C for "*y, like in MS-Windows.
8   When writing viminfo file, handle CTRL-J in filename (needs to be escaped
    with CTRL-V). (Acevedo)
8   When starting Vim, switch terminal to RAW mode asap, so typeahead is
    handled correctly (without the need for a <CR>).
8   When the value of $MAKE contains a path, configure can't handle this.
    It's an autoconf bug.  Remove the path from $MAKE to work around it.
8   How to set VIMRC_FILE to \"something\" for configure?  Why does this not
    work: CFLAGS='-DVIMRC_FILE=\"/mydir/myfile\"' ./configure
8   The temporary file is sometimes not writable.  Check for this, and use an
    alternate name when it isn't.  Or add the 'temptemplate' option: template
    for the temp file name ":set temptemplate=/usr/tmp/?????.tmp".
    Also: Win32 version uses Windows temp directory, which might not work for
    cygwin bash.
7   Get error "*, \+ or \( operand could be empty" for pattern "\(.\)\1\{3}".
    Don't check when compiling, check while matching?
7   When switching to Daylight Saving Time, Vim complains that a file has been
    changed since last read.  Can we use a function that uses GMT?
7   When completing an environment variable after a '$', check for file names
    that contain a '$' after all have been found.


I can't reproduce these (if you can, let me know how!):
-   With backupdir=~/tmp,/tmp nowritebackup nobackup patchmode=.smr and the
    patchmode file exists, backup files in the tmp directory are left lying
    around - they should be deleted! (Riehm)
9   Crash when changing fonts in Athena (Hiebert).  gui_mch_set_scrollbar_pos
    gets an "sb" argument that points to all zero entries...?
9   Crash in Motif GUI, when pasting text with middle mouse button while in
    Insert mode.  SunOS 4.1.3 only? (Janssen).
8   Motif: Tear-off menu item crashes Vim on some machines.  (Netherton)  It
    works fine for me, maybe it's a Motif problem.
-   On Diamond Viper 132x43 mode crash on exit (John Lange)
9   NT 4.0: Editing ".bashrc" (drag and drop), file disappears.
    Editing ".xyz" is OK. (McCollister)
8   Win32 GUI: NT: When regaining focus at the more prompt, there is an extra
    newline. (Webb)
8   Win32 GUI: Writable File in read-only dir can be deleted but not written?
    (Canup)
9   GUI: Between version 5.0h and 5.0i the Home and End keys stopped working
    for Micheal Schulz (Linux and AIX).
9   Win32 console: <M-S-Left> causes a crash. (Geddes)
9   In MSDOS version(s): typing ESC three or four times crashes Vim, when
    'visualbell' is set (Kielhorn).


[These have been reported for version 3.0, they may not appear in this version]
-   MSDOS: After writing on a network the 'w' bit for others is set.


Problems that will (probably) not be solved:
-   X windows: When $DISPLAY points to a X server where there is no access
    permission, trying to connect to the X server causes an error message.
    XtOpenDisplay() prints this directly, there is no way to avoid it.
-   X windows: Setting 'guifontset' to an illegal value sometimes crashes Vim.
    This is caused by a fault in a X library function, can't be solved in Vim.
-   Moving the cursor removes color in color-xterm.  This is a color-xterm
    problem!  color-xterm ver. 6.1 beta 3 and later work properly.
-   The Dos32 version (DJGPP) can't use long file names on Windows NT.
-   In zsh, "gvim&" changes the terminal settings.  This is a zsh problem.
    (Jennings)
-   Problem with HPterm under X: old contents of window is lost (Cosentino).
-   Amiga: When using quickfix with the Manx compiler we only get the first 25
    errors.  How do we get the rest?
-   Amiga: The ":cq" command does not always abort the Manx compiler.  Why?
-   Linux: A file with protection r--rw-rw- is seen readonly for others. The
    access() function in GNU libc is probably wrong.
-   MSDOS: When using smartdrive with write-back buffering, writing to a
    readonly floppy will cause problems.  How to test for a writable floppy
    first?
-   MSDOS: Both 16 and 32 bit versions: File name expansion doesn't work for
    names that start with a dot.  These used to be illegal file names.
-   When doing a CTRL-Z and typing a command for the shell, while Vim is busy
    (e.g. writing a file), the command for the shell is sometimes eaten by Vim,
    because the terminal mode is changed from RAW to CBREAK.
-   An old version of GNU tgoto can't handle the terminfo code for "AF".  The
    "%p1" is interpreted as "%p" and "1", causing color not to be working.
    Fix: Change the "%p1" in the "AF" and "AB" terminfo entries to "%p".
    (Benzinger).
-   When running an external command from the GUI, typeahead is going to that
    program, not to Vim.  It looks like the shell eats the characters, Vim
    can't get back what the external command didn't use.
-   Win32 GUI: Error code from external command not returned in shell_error.
    It appears that cmd.exe and command.com don't return an error code.
-   Win32 GUI: The Toolbar is a bit too high when the flat style is being
    used.  We don't have control over the height of the Toolbar.
-   Win32: All files created on the day of switching from winter to summer
    time cause "changed since editing started" messages.  It goes away when
    the file is written again the next day, or the timezone is adjusted.
    DJGPP version is OK. (Zaimi)  Looks like a problem with the Win32 library.
    Rebooting doesn't help.  Time stamps look OK in directory. (Penn)
    Is this on FAT (stores wall clock time) or NTFS (stores UTS)?
-   SunOS 5.5.1 with Motif: The file open dialog does not have a horizontal
    scroll bar for the "files" selection.  This is a problem in the Motif
    libraries, get a patch from Sun.
-   Solaris 2.6 with GTK and Perl: gvim crashes when started.  Problem with X
    input method called from GDK code.  Without Perl it doesn't crash.
-   Win32 GUI: mouse wheel always scrolls rightmost window.  The events arrive
    in Vim as if the rightmost scrollbar was used.
-   GTK with Gnome: Produces an error message when starting up:
	Gdk-WARNING **: locale not supported by C library
    This is caused by the gnome library gnome_init() setting $LC_CTYPE to
    "en_US".  Not all systems support this locale name, thus causing the
    error.  Hopefully a newer version of GTK/Gnome fixes this problem.

---------------------  extensions and improvements ----------------------
						    *extensions-improvements*

Documentation:
9   Merge in ideas from ~/vim/patches/tutor.txt (Gabriel Zachmann)
9   Update the overview of options in quickref.txt.
9   Errors in doc to HTML conversion:
    autocmd.txt "like \| in a |pattern|"
9   Add 'fold' section to quick reference.
9   Add new options to quick reference.
9   Change all tags for commands from i_<C-R>_<C-O> to i_CTRL-R_CTRL-O to
    avoid giving the user the impression that all commands have a tag in the
    <C-x> form.
9   Extend the User Manual.  Use portions of the Reference Manual.
9   Make the Reference Manual more precise.  For each command mention:
    - change to cursor position and curswant
    - if it can be undone (u/CTRL-R) and redone (.)
    - how it works for folded lines
    - how it works with multi-byte characters
9   In change.txt, remark about Javadoc isn't right.  Right alignment would
    work too.
8   Spread the windows commands over the other files.  For example, ":stag"
    should be with ":tag".  cross-link with tags to avoid too much double
    text.
8   make vimtutor.bat for DOS and vimtutor script for Amiga.  Then add
    vimtutor.man to the runtime archive.
8   Add an example vimrc for using Vim as a modeless editor.  Emulate an
    existing editor (WordStar, Emacs, Brief?).
7   Windows: When a wrong command is typed with an ALT key, give a hint to
    look at the help for 'winaltkeys'.
-   Check text editor compendium for vi and Vim remarks.
-   Add some text for xxd.


Help:
-   First try using the ":help" argument literally, before using it as a
    pattern.  And then match it as part of a tag.
-   When a help item has multiple matches make it possible to use ":tn" to go
    to the other matches.
-   Use GNU Texinfo for the help files somehow?  Use Info format files?
    At least the other way around: Use Vim to view (and edit) .info files.
-   Default mapping for help files: <Tab> to position cursor on next |:tag|.
-   When hitting <Esc> or CTRL-C in Normal mode, give a message to help novice
    users to get out: "Type  :q!  to quit Vim".
-   Implement a "sticky" help window, some help text lines that are always
    displayed in a window with fixed height. (Guckes)  Use "~/.vimhelp" file,
    user can edit it to insert his favorite commands, new account can contain a
    default contents.
-   When entering the help window, don't resize to 'helpheight' if the user has
    reduced the size before (Webb). Keep the window height that the user set
    the window to in a "preferred window height" entry for each window.
-   ":help :s^I" should expand to ":help :substitute".
-   Make the help key (<F1>) context sensitive?
-   Learn mode: show short help while typing commands.


"make test":
-   Find a way to skip tests that can't be done.  For non-Unix systems, but
    also for e.g. the Perl interface.


Folding:
    (commands still available: zg zG zI zJ zK zp zP zq zQ zV zw zW zy zY;
    secondary: zB zS zT zZ)
-   When pressing the down arrow of a scrollbar, a closed fold doesn't scroll
    until after a long time.  How to make scrolling with closed folds
    smoother?
-   When a buffer becomes hidden, keep the manual folds for it?
-   'foldmethod' "textobject": fold on sections and paragraph text objects.
-   Add 'hidecomment' option: don't display comments in /* */ and after //.
-   "zu": undo change in manual fold. "zU" redo change in manual fold.  How to
    implement this?
-   "zJ" command: add the line or fold below the fold in the fold under the
    cursor.
-   'foldmethod' "syntax": "fold=3": set fold level for a region.
-   Can set 'foldtext' to empty string: don't display any line.  How to
    implement this?


Multi-byte characters:
8   UTF-8: When there is a precomposed character in the font, use it instead
    of a character and a composing character.  See xterm for an example.
-   GTK and Win32: Allow selecting fonts for 'guifontset' with the
    fontselector somehow.
-   GTK and Win32: make it possible to set the font for the menu to make it
    possible to have 'encoding' different from the current locale.
-   dbcs_class() only works for Japanese and Korean.  Implement this for
    other encodings.  The "euc-jp" and "euc-kr" choices might be wrong.
-   Find some way to automatically select the right GUI font or fontset,
    depending on the default value of 'encoding'.
    For Windows, the charset_pairs[] table could be used.  But how do we know
    if a font exists?
-   Do keyboard conversion from 'termencoding' to 'encoding' with
    convert_input() for Mac GUI, RiscOS GUI, BeOS GUI, VMS.
-   Add mnemonics from RFC1345 longer than two characters.
    Support CTRL-K _{mnemonic}_
-   Do we need the reverse of 'keymap', like 'langmap' but with files and
    multi-byte characters?
-   When breaking a line, take properties of multi-byte characters into
    account.  The "linebreak" program from Bruno Haible can do it:
    ftp://ftp.ilog.fr/pub/Users/haible/gnu/linebreak-0.1.tar.gz
    But it's very complicated...


Ease of use:
-   Add a way to save local settings and mappings into a new plugin file.
    ":mkplugin <file>"?
9   Buffer-local autocommands?
	:au BufEnter <current> menu enable ...
	:au BufLeave <current> menu disable ...
-   Add mappings local to a window: ":map <window> ..."?
9   Add buffer-local menu.  Should offer a choice between removing the menu or
    disabling it.  Be careful that tear-offs don't disappear (keep one empty
    item?).
    Alternative: use BufEnter and BufLeave autocommands.


Syntax highlighting:
8   Allow the user to add items to the Syntax menu sorted, without having to
    change this for each release.
8   Add a "matchcontains" for regions: items contained in the start or end
    pattern, but not in the body.
8   Add a "keepend-contained" argument: Don't change the end of an item this
    one is contained in.  Like "keepend" but specified on the contained item,
    instead of the containing item.
8   For keywords, allow to define the size of the hash table with ":syn
    clear".  Change KHASH_ defines into variables stored in buffer struct.
    Use something else than linear linked list from the hash table. (Campbell)
8   cpp.vim: In C++ it's allowed to use {} inside ().
8   Some syntax files set 'iskeyword'.  When switching to another filetype
    this isn't reset.  Add a special keyword definition for the syntax rules?
8   Add specific syntax item to match with parens/braces that don't have a
    "%" match.  :syntax nomatch cMatchError (,{,[,),},] [contained]
8   Highlight the text between two matching parens (e.g., with a grey
    background) when on one of the parens or in between them.
8   Add a command to jump to the next character highlighted with "Error".
8   When using a cterm, and no ctermfg or ctermbg are defined, use start/stop
    sequences.	Add remark in docs that :if 'term' == "term-name" should be
    used.
8   Add @spell cluster to String and Comment groups for many languages.  Will
    allow spell checking. (Fleiner)
8   When listing syntax items, try to sort the keywords alphabetically.  And
    re-insert the [] if possible.
8   Make it possible to use color of text for Visual highlight group (like for
    the Cursor).
8   "fg" and "bg" don't work in an xterm.  Get default colors from xterm with
    an ESC sequence.  Ideas in: ~/vim/patches/vikas.xtermcolors .
8   Make it possible to only highlight a sub-expression of a match.  Like
    using "\1" in a ":s" command.
8   Support for deleting syntax items:
    :syn keyword cTodo remove this
    :syn match cTodo remove "pattern"
    :syn region cString remove start="this" end="that"
8   Add possibility to sync on something else, when the syncing in one way
    doesn't find match.  For HTML: When no {script} is found, try looking for
    a '<'.  (Fleiner)
7   Replace the synchronizing method with a state machine specification?
    Should be able to start at any line in the file, search forwards or
    backwards, and use the result of matching a pattern.
7   Use parsing like awk, so that e.g., a ( without a matching ) can be
    detected.
8   Make it possible to use "inverted" highlighting, invert the original
    character.  For Visual mode. (xterm-selection already does this).
8   Highlight non-printable characters with "SpecialChar", linked to
    "Special".  Display them with the digraph characters, if possible.
8   Highlight the clipboard-selection with a highlight group.
8   Be able to reset highlighting to its original (default) values.
7   Be able to write current highlighting to a file as commands, similar to
    ":mkvimrc".
8   Improve c.vim:
    - Add check for unterminated strings, with a variable to switch it on:
      "c_strict_ansi".
    - Detect unbalanced "#endif".  Requires looking back a long way...
8   Add an option to restrict the updating of syntax highlighting to the
    current line while in Insert mode.
8   When guessing value of 'background', the syntax file has already been
    loaded (from the .gvimrc).	After changing 'background', load it again?
8   Add ":syn resync" command, to re-parse the whole file until the current
    display position.
8   Should support "me" offset for a region start pattern.  To be used to
    allow searching for the end pattern inside the match of the end pattern.
    Example: syn region pikeXX start="([^{]" end=")" should work on "()".
8   When using a regexp for "contains=", should delay matching with it until
    redrawing happens.  Set a flag when a group is added, check this flag when
    highlighting starts.
7   Add "semitrans": Add highlighting.  E.g., make the text bold, but keep the
    colors.  And add colors, so that Green+Red becomes Yellow.
    E.g. for this html:
	<B> bold text <I> italic+bold text </B> italic text </I>
7   Wild idea: Not only set highlighting, but also change what is displayed
    (e.g., remove characters, so that "<B>bold</B>" can be shown as "bold"):
	:syn region boldstuff start="<B>" display="" end="</B>" display=""
7   CTRL-] checks the highlight group for finding out what the tag is.
7   Add an explanation how a list of words can be used to highlight misspelled
    words.
8   Add spell checking.  Use "ispell -a" somehow.
    ~/vim/patches/wm_vim-5_4d.zip  can be used as an example (includes ispell
    inside Vim).
7   Command line completion for ":find" should search in 'path'.
8   Add more command line completion for :syntax.
8   Add more command line completion for :highlight.
7   Should find a better way to parse the :syntax and :highlight commands.
    Use tables or lists that can be shared by parsing for execution and
    completion?
7   Add a few sets of colors (e.g. Borland Turbo C one).  With a menu to
    select one of the sets.
8   Add offsets to sub-matches: "\(a*\) *"he=e1-1
    'e' is end of match 'e1' is end of sub-match 1, 's2' is start of submatch
    2, etc.
8   In Insert mode, when there are typeahead characters, postpone the
    highlighting (for "." command).
8   Syncing on comments isn't 100% correct when / / lines mix with / * and * /.
    For example: What about a line that starts with / / and contains * /?
8   Ignore / * and  * / inside strings, when syncing.
7   Build a few more syntax files from the file "/usr/share/misc/vgrindefs":
    ISP, LDL, Icon, ratfor.  And check "nedit/source/highlight.c".
6   Add possibility to have background color continue until the right edge of
    the window.  Useful for comment blocks and function headings. (Rogall)
-   Make it possible to add "contains" items for all items in a group.	Useful
    when extending an already existing syntax file.
-   Add line-continuation pattern for non-syncing items too?
-   Add possibility to highlight specific columns (for Fortran).  Or put a
    line in between columns (e.g. for 'textwidth').
-   Add possibility to highlight the whole line, including the right margin
    (for comment blocks).
-   Add 'hlmatch' option: List of flags:
    'c': highlight match for character under the cursor.
    'b': highlight the previous (, and its match.
    'a': highlight all text from the previous ( until its match.
	 Also for {}, <>, etc.?
    'e': highlight all braces without a match (slow?)
    OR: add an argument "cursor" to the syntax command, which means that the
    region/match/keyword is only highlighted when the cursor is on it.
    (Campbell)
    Or do it like Elvis: define text objects and how to highlight them around
    the cursor. (Iain Truskett)
7   Make it possible to use all words in the tags files as Keyword.
    Can also be done with a script (but it's slow).
7   Make it possible to call a ":" command when a match is found.  Should
    allow for adding keywords from the text (e.g. variables that are set).
    And allows for sections with different highlighting.
7   Add highlight group for commandline: "Commandline".  Make sure it
    highlights the command line while typing a command, and any output from
    messages.  And external commands?
8   Make a version that works like less, but with highlighting: read stdin for
    text, exit at end of file, don't allow editing, etc.  moreim?  lessim?


Built-in script language:
8   Add referring to key options with "&t_xx".  Both for "echo &t_xx" and
    ":let &t_xx =".  Useful for making portable mappings.
8   Allow range for ":exec".  Pass it on to the executed command. (Webb)
8   Add a way to catch errors:
	:try
	:  [commands that can fail]
	:catch [error-type]
	:  [error handling]
	:endtry
7   Be able to call a function while passing on a variable number of
    arguments:
	:function Foo(abc, ...)
	:  call Bar(a:abc, ...)    of call Bar(a:abc, a:*)
8   Have a look at VSEL.  Would it be useful to include? (Bigham)
8   Add ":fungroup" command, to group function definitions together.  When
    encountered, all functions in the group are removed.  Suggest using an
    obscure name to avoid name clashes.  Require a ":fungroup END" in the same
    sourced file?  Assume the group ends at the end of the file.  Handle
    nested packages?
    Alternative: Support packages.  {package-name}:{function-name}().
    Packages are loaded automatically when first used, from
    $VIMRUNTIME/packages (or use a search path).
7   Pre-parse or compile Vim scripts into a bytecode.  Put the bytecode with
    the original script, with an ":if has('bytecode')" around it, so that it's
    only used with a Vim that supports it.
8   The input() function should not read mapped characters, but always get
    characters from the user (or a script).  Need to change vgetorpeek() to
    ignore mapped characters.
8   Add functions:
	cursor(lnum, col)	Position cursor (when lnum or col 0 keep val)
	multibyteidx(string, idx) Byte index in multi-byte character.
	menuname({menu_name}, {idx})  get name of menu.  menuname("", 1)
				returns "File", menuname("File", 1) returns
				"Open...".
	menuarg({menu_name})	return argument of a menu item by name.
	mapname({idx}, mode)	return the name of the idx'th mapping.
	match({pat}, {string}, [count]) get index of count'th match
	sprintf(format, arg, ..) How to prevent a crash???
	attributes()		return file protection flags "drwxrwxrwx"
	perl(cmd)		call Perl and return string
	shorten(fname)		shorten a file name, like home_replace()
	input(prompt, complete)	like input() but do specified completion
	tagtype(tag)		get type of tag (also checks if it exists)
	filewritable()		like filereadable()
	getfperm()		file permissions, in form "rwxrwxrwx"
	getftype()		"file", "dir", "link", "other"?
	getbufvar({bufid}, {name})
	setwinvar()
	getwinvar()
	search()		Add optional offset argument.
	libcall()		Allow more than one argument.
	libcallnr()		Like libcall(), but function returns a number.
	fnamemod({fname}, {mod})    {mod} can be ":p:h" etc., to be applied to
				{fname}
	getchar()		get one character from the user.
	confirm()		add "flags" argument, with 'v' for vertical
				layout and 'c' for console dialog.  Also add
				'c' to 'guioptions' (for all dialogs) (Haegg)
	filter({cmd} [, {string}])  Filter {string} through the shell command
				{cmd} and return the result.  If {string} is
				omitted no input is given to {cmd}.
	getkey()		Like input() but get only one char.
	raisewin()		raise gvim window (see HierAssist patch for
				Tcl implementation ~/vim/HierAssist/ )
8   argc() returns 0 when using "vim -t tag".  How to detect that no file was
    specified in any way?  To be able to jump to the last edited file.
8   When starting to source a vim script, delete all functions that it has
    previously defined?  Avoids using ":fun!" all the time.
7   Add optional arguments to user functions:
	:func myFunc(arg1, arg2, arg3 = "blah", arg4 = 17)
6   User functions: Functions local to buffer "b:func()"?
8   Add ":let var[{expr}] = {expr}".  When past the end of "var" just ignore.
8   The "= register should be writable, if followed by the name of a variable,
    option or environment variable.
8   ":let &option" should list the value of the option.
7   Add synIDlist(), making the whole list of syntax items on the
    stack available (separated with '\n').
8   Add autocommand-event for when a variable is changed:
	:au VarChanged {varname} {commands}
8   Add "has("gui_capable")", to check if the GUI can be started.
8   Add possibility to use variables like registers: characterwise (default),
    linewise (when ending in '\n'), blockwise (when ending in '\001').	reg0,
    rega, reg%, etc.  Add functions linewise({expr}), blockwise({expr}) and
    charwise({expr}).
7   Make it possible to do any command on a string variable (make a buffer
    with one line, containing the string).  Maybe add an (invisible) scratch
    buffer for this?
	result = scratch(string, command)
	result = apply(string, command)
	result = execute(string, command)
    "command" would use <> notation.
    Does scratch buffer have a number?  Or re-use same number?
7   Add function to generate unique number (date in milliseconds).
7   Automatically load a function from a file when it is called.  Need an
    option for the search path. (Sekera)
7   Include support for arrays?  Patch from Robert Webb.
    This is restricted to fixed-size arrays indexed by number.  Better: Use
    associative arrays: a[5] = 3, a["some"] = 'x'. Implement by translating
    into ordinary variables: a[5] is "-a-5", a["some"] is "a-some", a[5][6] is
    "a-5-6".  But how to do array assignment and concatenation?


Performance:
8   Avoid alloc() for scratch buffer use, esp. in syntax.c.  It's very slow on
    Win16.
9   Setting GUI options in the console (e.g., 'guifont') should not cause a
    redraw.
8   Profiling shows that in_id_list() is used very often for C code.  Can this
    function be improved?
8   For an existing file, the page size of the swap file is always the
    default, instead of using the block size of the device, because the swap
    file is created only after setting the block size in mf_open().  How can
    this be improved?
8   Set default for 'ttyscroll' to half a screen height?  Should speed up
    MS-DOS version. (Negri)
7   Check how performance of loading the wordlist can be imrpoved (adding a
    lot of abbreviations).
7   DOS console: Add t_DL support, to make scrolling faster.
7   Compile Ex commands to byte codes.  Store byte codes in a vim script file
    at the end, after "compiled:.  Make it look like a single comment line
    for old Vim versions.  Insert first line "Vim script compiled <timestamp>.
    Only used compiled code when timestamp matches the file stat.
    Add command to compile a vim script and add it to the file in-place.
    Split Ex command executing into a parsing and executing phase.
    Use compiled code for functions, while loops, etc.
8   When editing a file with extremely long lines (e.g., an executable), the
    "linerest" in readfile() is allocated twice to be able to copy what was
    read so far.  Use realloc() instead?  Or split the line when allocating
    memory fails and "linerest" is big (> 100000)?
8   When defining autocommands (e.g., from $VIMRUNTIME/filetype.vim), need to
    compare each pattern with all existing patterns.  Use a hash code to avoid
    using strcmp() too often?
7   Include turbo_loader patches, speeding up reading a file?
    Speed up reading a file by reading it into a fixed-size buffer, creating
    the list of indexes in another buffer, and then copying the result into a
    memfile block with two copies.  Then read the next block into another
    fixed-size buffer, create the second list of indexes and copy text from
    the two blocks to the memfile block.
7   do_cmdline(): Avoid that the command line is copied to allocated memory
    and freed again later all the time.  For while loops, and for when called
    with an argument that can be messed with.
    Generic solution: Make a struct that contains a pointer and a flag that
    indicates if the pointer should be freed when replaced.
7   Check that that the file size is not more than "sizeof(long)".
-   Further improve finding mappings in maphash[] in vgetorpeek()
8   Dragging the status line doesn't scroll but redraw.
8   Syntax highlighting is slow when deleting lines.  Try in
    $VIMRUNTIME/filetype.vim.
-   "out of memory" after deleting (1,$d) and changing (:%s/^/> /) a lot of
    lines (27000) a few times.  Memory fragmentation?
-   Have a look at how pdksh does memory allocation (alloc.c). (Dalecki)
-   Do profiling on:
    - :g/pat/normal cmd
    - 1000ii<Esc>
    - deleting 10Mbyte worth of lines (netscape binary)
    - ":g/^/m0" on a 450Kbyte file.  And the "u".
    - highlighting "~/vim/test/longline.tex", "~/vim/test/scwoop.tcl" and
      "~/vim/test/lockup.pl".
    - loading a syntax file to highlight all words not from a dictionary.
    - editing a vim script with syntax highlighting on (loading vim.vim).
7   Screen updating can be further improved by only redrawing lines that were
    changed (and lines after them, when syntax highlighting was used, and it
    changed).
    - On each change, remember start and end of the change.
    - When inserting/deleting lines, remember begin, end, and line count.
-   Use macros/duarte/capicua for profiling.  Nvi 1.71 is the fastest!
-   When using a file with one long line (1Mbyte), then do "$hhhh", is still
    very slow.  Avoid calling getvcol() for each "h"?
-   Executing a register, e.g. "10000@@" is slow, because ins_typebuf has to
    move the previous commands forward each time.  Pass count from
    normal_cmd() down to do_execreg().
-   Repeating insert "1000i-<Esc>" displays --INSERT-- all the time, because of
    the <Esc> at the end.  Make this work faster (disable redrawing).
-   Avoid calls to plines() for cursor line, use w_cline_height.
-   When only need to redraw the status lines in status_redraw_all(), need to
    update NOT_VALID to force the redraw.  Should detect that only the status
    lines need to be redrawn (add STATUSLN between VALID and NOT_VALID?).
-   After :set nowrap remove superflous redraw with wrong hor. offset if cursor
    is right of the screen.


Code size:
8   GUI: When NO_CONSOLE is defined, more code can be excluded.
-   Put getline() and cookie in a struct, so only one argument has to be
    passed to do_cmdline() and other functions.
8   move common files between os_unix.c and os_vms.c to one file?
8   Make a GUI-only version for Unix?

    lines that aren't executed?  Perhaps move the echoing to do_cmdline()?
8   Use 'report' for ":bdel"?  (Krishna)  To avoid these messages when using a
    script.
8   "vim --version" output goes to stderr, should be stdout.  Can all output
    from messages using printf() go to stdout?
-   Delete message after new command has been entered and have waited for key.
    Perhaps after ten seconds?
-   Make message history available in "msg" variables: msg1, msg2, .. msg9.
9   Check handling of overwriting of messages and delays:
    Very wrong: errors while redrawing cause endless loop.
    When switching to another file and screen scrolls because of the long
    message and return must be typed, don't scroll the screen back before
    redrawing.
7   Add an option, which is a regexp, that disables warning messages which
    match that regexp (Tsirkin).
8   When address range is wrong you only get "Invalid range".  Be a bit more
    specific: Negative, beyond last line, reverse range?  Include the text.
8   Make it possible to ignore errors for a moment ('errorignore'?).  Another
    option to switch off giving error messages ('errorquiet'?).  Also an option
    not to give any messages ('quiet')?  Or ":quiet on", ":quiet off".
    Careful: For a severe error (out of memory), and when the user starts
    typing, error messages must be switched back on.
    Also a flag to ignore error messages for shell commands (for mappings).
-   Option to set time for emsg() sleep. Interrupt sleep when key is typed?
    sleep before second message?
8   In Ex silent mode or when reading commands from a file, what exactly is
    not printed and what is?  Check ":print", ":set all", ":args", ":vers",
    etc.  At least there should be no prompt. (Smulders)  And don't clear the
    screen when reading commands from stdin. (Kendall)
    --> Make a difference between informative messages, prompts, etc. and
	error messages, printing text, etc.
8   Window should be redrawn when resizing at the hit-enter prompt.
    Also at the ":tselect" prompt.  Find a generic solution for redrawing when
    a prompt is present (with a callback function?).


Screen updating:
7   Add a string to the 'display' option to make CTRL-E and CTRL-Y scroll one
    screen line, also if this means the first line doesn't start with the
    first character (like what happens with a single line that doesn't fit).
-   screen_line():
    - insert/delete character stuff.
    - improve delete rest of line (spaces at end of line).
-   When moving or resizing window, try to avoid a complete redraw (esp. when
    dragging the status line with the mouse).
-   When 'lazyredraw' set, don't echo :ex commands?  Need a flag to redraw when
    waiting for a character.
8   Add a ":refresh [winnr]" command, to force updating a window.  Useful from
    an event handler where ":normal" can't be used.  Also useful when
    'lazyredraw' is set in a mapping.


Scrolling:
8   Add "zm" command: scroll horizontally to put the cursor in the middle.
6   Add option to set the overlap for CTRL-F and CTRL-B. (Garhi)
-   extend 'scrollbind' option: 'scrollopt' words "search", "relative", etc..
    Also 'e'xecute some commands (search, vertical movements) in all bound
    windows.
-   Allow scrolling by dragging with the mouse.  Like the "hand" in Acrobat
    reader.  With which mouse button?
-   Add command to execute some commands (search, vertical movements) in all
    bound windows.
-   Add 'search' option to 'scrollopt' to allow 'scrollbind' windows to
    be bound by regexp searches
-   Add "z>" and "z<": scroll sideways one screenfull. (Campbell)
-   Add option to set the number of lines when not to scroll, instead of the
    fixed number used now (for terminals that scroll slow with a large number
    of lines but not with a single line).


Autoconf:
8   Should use acconfig.h to define prototypes that are used by autoheader.
8   Some compilers don't give an error for "-OPT:Olimit" but a warning. (Webb)
    Add a check for the warning, so that "Olimit" can be added automatically?
-   Autoconf: Use @datadir@ for the system independent files.  Make sure the
    system dependend and system independed files are separated. (Leitner).
-   Add autoconf check for waitpid()/wait4().
-   Remove fcntl() from autoconf, all systems have it?
-   Set default for 'dictionary', add search for dictionary to autoconf.


Perl interface:
8   Rename typemap file to something else?
7   Make buffers accessed as Perl arrays. (Clark)
7   Make it possible to compile with non-ANSI C?
6   Tcl/Tk has the "load" command: load a shared library (.so or .dll).


Shared libraries:
6   Add support for loading shared libraries, and calling functions in it.
	:libload internal-name libname
	:libunload internal-name
	:liblist
	:libcall internal-name function(arg1, arg2, ...)
	:libcall function(arg1, arg2, ...)
    libcall() can have only one integer or String argument at the moment.
6   Have a look on how Perl handles loading dynamic libraries.


Tags:
8   Add a function that returns the line in the tags file for a matching tag.
    Can be used to extract more info (class name, inheritance, etc.) (Rico
    Hendriks)
7   Count before CTRL-]: jump to N'th match
8   Scope arguments for ":tag", e.g.: ":tag class:cPage open", like Elvis.
8   When output of ":tselect" is long, getting the more-prompt, should be able
    to type the tag number directly.
7   Add 'tagignorecase' option from Vile: ignore case for tags.
7   Make output of ":tselect" a bit nicer.  Use highlighting?
7   Highlight the "tag 1 of >2" message.  New highlight group, or same as "hit
    bottom" search message.
7   When using ":tag" at the top of the tag stack, should add another entry,
    so CTRL-T can bring you back to where you are now AND to where you were
    before the previous ":tag" command. (Webb)
7   When using CTRL-] on someClass::someMethod, separate class from method and
    use ":ta class:someClass someMethod".
    Include C++ tags changes (Bertin).	Change "class::func" tag into "func"
    with "class=class"?  Docs in oldmail/bertin/in.xxx.
7   Add ":tagargs", to set values for fields:
	:tagargs class:someclass file:version.c
	:tagargs clear
    These are then the default values (changes the order of priority in tag
    matching).
7   Support for "gtags" and "global"?  With ":rtag" command?
    There is an example for how to do this in Nvi.
    Or do it like Elvis: 'tagprg' and 'tagprgonce' options. (Yamaguchi)
    The Elvis method is far more flexible, do it that way.
7   Support "col:99" extra field, to position the cursor in that column.  With
    a flag in 'cpoptions' to switch it off again.
7   Better support for jumping to where a function or variable is used.  Use
    the id-utils, with a connection to "gid" (Emacs can do it too).  Add
    ":idselect", which uses an "ID" database (made by "mkid") like "tselect".
6   Don't store the search pattern from a tag command in the search history
    (with an option)?


Security:
-   nothing at the moment


Win32 GUI:
8   Make debug mode work while starting up (vim -D).  Open console window for
    the message and input?
8   Add font argument to set the lfCharSet. (Bobcik)
8   Could keep console open to run multiple commands, to avoid the need to hit
    return in every console.
    Also: Look at how Emacs does runs external commands:
	http://www.cs.washington.edu/homes/voelker/ntemacs.html.
8   When dropping a file onto gvim while at the ":" prompt, insert the file
    name.  Allows using the name with different commands. (Krishna)
8   Need a separate PopUp menu for modeless selection.  Need two new commands:
    Copy selection to clipboard, Paste selection (as typed text).
8   Dropping a file on a gvim that edits a modified buffer splits the window.
    Make an option to replace the current file (use ":e" instead of ":sp")?
    When dropping multiple files, display the first one and adjust the
    arglist.  Or make it an option for the user to chose betwen ":e" and ":sp"?
8   Support copy/paste for other file formats.  At least HTML, perhaps RTF.
    Add "copy special" and "paste special" commands?
7   Use <C-Tab> to cycle through open windows (e.g., the find dialog).
7   <Esc> should close a dialog.
7   Keep the console for external commands open.  Don't wait for a key to be
    hit.  Re-open it when the user has closed it anyway.  Or use a prepended
    command: ":nowait {cmd}", or ":quiet", which executes {cmd} without any
    prompts.
7   Should be able to set an option so that when you double click a file that
    is associated with Vim, you can either get a new instance of Vim, or have
    the file added into an already running Vim.


GUI:
9   Make <S-Insert> paste from the clipboard by default. (Kunze)
7   Menu local to a buffer, like mappings.  Or local to a filetype?
8   Dragging the mouse pointer outside of a Vim Window should make the text
    scroll.  Return a value from gui_send_mouse_event() to the machine
    specific code to indicate the time in which the event should be repeated.
8   Make it possible to ignore a mouse click when it's used to give Vim (gvim)
    window focus.  Also when a mouse click is used to bring a window to front.
8   Make the split into system independend code and system specific code more
    explicit.  There are too many #ifdefs in gui.c.
    If possible, separate the Vim code completely from the GUI code, to allow
    running them in separate processes.
8   Support a background bitmap.  Useful for marking a column.  Patch from
    Heather Downs (GTK) and Vince Negri (Win32).
7   X11: Support cursorColor resource and "-cr" argument.
8   X11 (and others): CTRL-; is not different from ';'.  Set the modifier mask
    to include CTRL for keys where CTRL produces the same ASCII code.
8   Visual highlighting should keep the same font (bold, italic, etc.).
8   Make the "Save As.." menu item work like other GUI programs: ":w file",
    ":e file".
8   Add 'c' flag in 'guioptios' to use console dialogs instead of GUI dialogs.
    Esp. for the ATTENTION prompt.
8   Add flag to 'guioptions' to not put anything in the clipboard at all?
8   Should take font from xterm where gvim was started (if no other default).
8   Selecting font names in X11 is difficult, make a script or something to
    select one.
8   Should support a way to use keys that we don't recognize yet.  Add a
    command that adds entries to special_keys somehow.	How do we make this
    portable (X11, Win32, ..)?
7   Add a flag to 'guioptions' that tells not to remove inactive menu items.
    For systems where greying-out or removing menu items is very slow.  The
    menu items would remain visibly normally, but not do anything.
7   Add ":minimize" and ":maximize", which iconize the window and back.
    Useful when using gvim to run a script (e.g. 2html.vim).
7   X11: Is it possible to free allocated colors, so that other programs can
    use them again?  Otherwise, allow disabling allocating the default colors.
    Or allocate an own colormap (check UAE).  With an option to use it.  For
    the commandline, "-install" is mostly used for X11 programs.
7   Add command line argument for "gvim" not to start the GUI.  Sort of the
    inverse of "vim -g". (Vikas)
6   Local buffer menus. (Zachmann)
7   Should support multi-column menus.
-   Should add option for where to put the "Help" menu: like Motif at the far
    right, or with the other menus (but still at the right).
-   Add menu item to "Keep Insert mode".
8   ":mkgvimrc" command, that includes menus.
6   Big change: Move GUI to separate program "vimgui", to make startup of vim a
    lot faster, but still be able to do "vim -g" or ":gui".
6   Make it possible to "drag the text" (grab a character and move it
    up/down).  Use Alt-LeftMouse for this?  (Goldfarb)
7   More explicit mouse button binding instead of 'mousemodel'?
7   Add option to set the position of the window on the screen.  'windowpos',
    which has a value of "123,456": <x>,<y>.
    Or add a command, like ":winsize"?
7   Add toolbar for non-Win32 GUIs.
7   Make it possible to put the toolbar on top, left, right and/or bottom of
    the window?  Allows for softkey-like use.
6   Separate the part of Vim that does the editing from the part that runs the
    GUI.  Communicate through a pseudo-tty.  Vim starts up, creates a
    pty that is connected to the terminal.  When the GUI starts, the pty is
    reconnected to the GUI process.  When the GUI stops, it is connected to
    the terminal again.  Also use the pty for external processes, it looks
    like a vt100 terminal to them.  Vim uses extra commands to communicate GUI
    things.
-   Motif steals <F10> from us, to pop up menus with the keyboard.  How do we
    get it back if we want it?
-   Paste in Insert mode should not do autowrap etc.  Or maybe this should be
    changeable with an option?
-   Put a nice picture in the icon (but how do we do that?).
7   When using a pseudo-tty Vim should behave like some terminal (vt52 looks
    simple enough). Terminal codes to/from shell should be translated.
-   Would it be useful to be able to quit the GUI and go back to the terminal
    where it was started from?


Autocommands:
9   Make sure that side effects of autocommands are handled correctly.  Don't
    execute autocommands when a buffer or window is halfway some changes.
    Move all apply_autocmds() calls to a higher level where needed.
8   Use another option than 'updatetime' for the CursorHold event.  The two
    things are unrelated for the user (but the implementation is more
    difficult).
8   Can't use ":normal" in CursorHold autocommands.  Make the CursorHold event
    insert a special key code, and call the autocommand functions from a
    higher level, so that vgetc() isn't used recursively.
8   Autocommands should not change registers.  And marks?  And the jumplist?
    And anything else?
8   Autocommand for when modified files have been found, when getting input
    focus again (e.g., FileChangedFocus).
    Check when: getting focus, jumping to another buffer, ...
8   Add autocommands, user functions and user commands to ":mkvimrc".
8   Add "TagJumpFile" autocommand: When jumping to another file for a tag.
    Can be used to open "main.c.gz" when "main.c" isn't found.
7   Add a way to skip an autocommand if going from one *.c file to another *.c
    file.
7   When trying to open a directory, don't load the file but trigger an
    autocommand event OpenDirectory.
7   Add file type in front of file pattern: <d> for directory, <l> for link,
    <x> for executable, etc.  <&xxx> for Risc OS.  With commas to separate
    alternatives.  The autocommand is only executed when both the file type
    AND the file pattern match. (Leonard)
5   Add option that specifies extensions which are to be discarded from the
    file name.  E.g. 'ausuffix', with ".gz,.orig".  Such that file.c.gz will
    trigger the "*.c" autocommands.  (Belabas)
7   Add something to break the autocommands for the current event, and for
    what follows.  Useful for a "BufWritePre" that wants to avoid writing the
    file.
8   Detect textmode after executing the autocommands, otherwise the .gz
    autocommands don't work for MS-DOS.  Needs to be able to remove the ^Ms at
    the end of each line.  Alternative: don't use a filter command, write the
    file, gunzip, set nobin, delete the lines, read the file.
8   Add buffer-local autocommands?  Reduces overhead for autocommands that
    trigger often (inserting a character, switching mode).
	:au Event <buffer> do-something
-   Add events to autocommands:
    Error	    - When an error happens
    NormalEnter	    - Entering Normal mode
    InsertEnter	    - Entering Insert mode
    ReplaceEnter    - Entering Replace mode
    CmdEnter	    - Entering Cmdline mode
    VisualEnter	    - Entering Visual mode
    *Leave	    - Leaving the mode
    SearchPost	    - After doing a search command (e.g. to do "M")
    PreDirChanged/PostDirChanged
		    - Before/after ":cd" has been used (for changing the
		      window title)
    BufReadAction   - replaces reading a file
    BufWriteAction  - replaces writing a file
    ShutDown	    - when the system is about to shut down
    InsertCharPre   - user typed character Insert mode, before inserting the
		      char.  Set v:char to the character, can be changed. (not
		      when 'paste' is set).
    InsertCharPost  - user typed a character in Insert mode, after inserting
		      the char.
    BufModified	    - When a buffer becomes modified, or unmodified (for
		      putting a [+] in the window title or checking out the
		      file from CVS).
    BufFirstChange  - When making a change, when 'modified' is set.  Can be
		      used to do a :preserve for remote files.
    BufChange	    - after a change was made.  Set some variables to indicate
		      the position and number of inserted/deleted lines, so
		      that marks can be updated.  HierAssist has patch to add
		      BufChangePre, BufChangePost and RevertBuf. (Shah)
-   Add autocommand to be executed every so many seconds?  For writing the
    file now and then ('autosave').
				  *'autosave'* *'as'* *'noautosave'* *'noas'*
    'autosave' 'aw' number  (default 0)
	    Automatically write the current buffer to file N seconds after the
	    last change has been made and when |'modified'| is still set.
	    Default: 0 = do not autosave the buffer.


Insert mode completion/expansion:
9   ^X^L completion doesn't repeat correctly.  It uses the first match with
    the last added line, instead of continuing where the last match ended.
    (Webb)
8   The code has become too complex.  Redesign it, or at least add proper
    comments.
8   Add option to set different behavior for Insert mode completion:
    - ignore/match case
    - different characters than 'iskeyword'
8   Add a command to undo the completion, go back to the original text.
8   Use the class information in the tags file to do context-sensitive
    completion.  After "foo." complete all member functions/variables of
    "foo".  Need to search backwards for the class definition of foo.
    Should work for C++ and Java.
    Even more context would be nice: "import java.^N" -> "io", "lang", etc.
7   When expanding $HOME/dir with ^X^F keep the $HOME (with an option?).
7   Add CTRL-X command in Insert mode like CTRL-X CTRL-N, that completes WORDS
    instead of words.
8   Add CTRL-X CTRL-R: complete words from register contents.
8   Add completion of previously inserted texts (like what CTRL-A does).
    Requires remembering a number of insertions.
8   Add 'f' flag to 'complete': Expand file names.
    Also apply 'complete' to whole line completion.
-   Make it possible to search include files in several places.  Use the
    'path' option?  Can this be done with the dictionary completion (use
    wildcards in the file name)?
-   Make CTRL-X CTRL-K do a binary search in the dictionary (if it's sorted).
-   Speed up CTRL-X CTRL-K dictionary searching (don't use a regexp?).
-   Set a mark at the position where the match was found (file mark, could
    be in another file).
-   Add CTRL-A command in CTRL-X mode: show all matches.
-   Make CTRL-X CTRL-L use the 'complete' option?
-   Add command in CTRL-X mode to add following words to the completed string
    (e.g. to complete "Pointer->element" with CTRL-X CTRL-P CTRL-W CTRL-W)
-   CTRL-X CTRL-F: Use 'path' to find completions.
-   CTRL-X CTRL-F: Don't replace "$VIM" with the actual value. (Kelly)
8   Add option 'isexpand', containing characters when doing expansion (so that
    "." and "\" can be included, without changing 'iskeyword'). (Goldfarb)
    Also: 'istagword': characters used for CTRL-].
    When 'isexpand' or 'istagword' are empty, use 'iskeyword'.


Command line editing:
7   Add commands (keys) to delete from the cursor to the end of the command
    line.
-   Add flags to 'whichwrap' for command line editing (cursor right at end of
    lines wraps to start of line).
-   Make editing the command line work like Insert mode in a single-line view
    on a buffer that contains the command line history.  But this has many
    disadvantages, only implement it when these can be solved.  Elvis has run
    into these, see remarks from Steve (~/Mail/oldmail/kirkendall/in.00012).
    - Going back in history and editing a line there would change the history.
      Would still need to keep a copy of the history elsewhere.  Like the
      cmdwin does now already.
    - Use CTRL-O to execute one Normal mode command.  How to switch to normal
      mode for more commands?  <Esc> should cancel the command line.  CTRL-T?
    - To allow "/" and "= need to recursively call getcmdline(), overwrite the
      cmdline.  But then we are editing a command-line again.  How to avoid
      that the user gets confused by the stack of command lines?
    - Use edit() for normal cmdline editing?  Would have to integrate
      getcmdline() into edit().  Need to solve conflicts between Insert mode
      and Command-line mode commands.  Make it work like Korn shell and tcsh.
      Problems:
	- Insert: completion with 'wildchar'
	- Insert: use cmdline abbreviations
	- Insert: CTRL-D deletes indent instead of listing matches
	- Normal: no CTRL-W commands
	- Normal: no ":" commands?
	- Normal: allow Visual mode only within one line.
    - where to show insert/normal mode message?  Change highlighting of
      character in first column?
    - Implementation ideas:
      - Set "curwin" and "curbuf" to the command line window and buffer.
      - curwin->w_topline is always equal to curwin->w_cursor.lnum.
      - never set 'number', no folding, etc.  No status line.
      - sync undo after entering a command line?
      - use NV_NOCL flag for commands that are not allowed in Command-line
	Mode.


Command line completion:
8   Change expand_interactively into a flag that is passed as an argument.
8   When completing command names, either sort them on the long name, or list
    them with the optional part inside [].
-   For 'wildmenu': Simplify "../bar" when possible.
-   When using <Up> in wildmenu mode for a submenu, should go back to the
    current menu, not the first one.  E.g., ":emenu File.Save<Up>".
8   For ":find" and ":sfind" expand files found in 'path'.
8   When using backtick expansion, the external command may write a greeting
    message.  Add an option or commands to remove lines that match a regexp?
7   When listing matches of files, display the common path separately from the
    file names, if this makes the listing shorter. (Webb)
-   Add command line completion for ":ilist" and friends, show matching
    identifiers (Webb).
8   Add command line completion for "old value" of a command.  ":args <key>"
    would result in the current list of arguments, which you can then edit.
6   Add command line completion with CTRL-X, just like Insert mode completion.
    Useful for ":s/word/xx/".
-   Add command to go back to the text as it was before completion started.
    Also to be used for <Up> in the command line.
-   Add 'wildlongest' option: Key to use to find longest common match for
    command line completion (default CTRL-L), like 'wildchar'. (Cregut)
    Also: when there are several matches, show them line a CTRL-D.
7   With command line completion after '%' and '#', expand current/alternate
    file name, so it can be edited.
-   Add completion for Environment variables: ":echo $SH<Tab>" -> "$SHELL".


Command line history:
-   Add "KeyWasTyped" flag: It's reset before each command and set when a
    character from the keyboard is consumed. Value is used to decide to put a
    command line in history or not. Put line in history if it didn't
    completely resulted from one mapping.
-   When using ":browse", also put the resulting edit command in the history,
    so that it can be repeated. (Demirel)


Insert mode:
9   When 'autoindent' is set, hitting <CR> twice, while there is text after
    the cursor, doesn't delete the autoindent in the resulting blank line.
    (Rich Wales) This is Vi compatible, but it looks like a bug.  Rich has a
    suggestion for a patch to fix this.
8   When using CTRL-O in Insert mode, then executing an insert command
    "a" or "i", should we return to Insert mode after <Esc>? (Eggink)
    Perhaps it can be allowed a single time, to be able to do
    "<C-O>10axyz<Esc>".  Nesting this further is confusing.
    ":map <F2> 5aabc<Esc>" works only once from Insert mode.
7   Make ":startinsert" command work directly for functions and scripts?
    Also make it possible to append (it's difficult at end of line).
-   In Insert mode (and command line editing?): Allow undo of the last typed
    character.	This is useful for CTRL-U, CTRL-W, delete and backspace, and
    also for characters that wrap to the next line.
    Also: be able to undo CTRL-R (insert register).
    Possibly use 'backspace'="whole" for a mode where at least a <CR> that
    inserts autoindent is undone by a single <BS>.
-   Use CTRL-G in Insert mode for an extra range of commands, like "g" in
    Normal mode.
-   Make 'paste' work without resetting other options, but override their
    value.  Avoids problems when changing files and modelines or autocommands
    are used.
-   When typing CTRL-V and a digit higher than 2, only expect two digits.
-   Insert binary numbers with CTRL-V b.
-   Make it possible to undo <BS>, <C-W> and <C-U>.  Bash uses CTRL-Y.


'cindent', 'smartindent':
9   When using 'cino' "f1s" the indent after a function is set to the indent
    of the "}", should be zero.
9   Formatting comments should use 'comments' setting.  E.g. when lining out
    comments like this:
	/*
	** formatted with comments=sr:/*,mb:**,ex:*/
	*/
9   One indent to much when doing "o" below this "while": (Rouben Rostamian)
	{
	    do
		if (1) {
		    asdf;
		} else
		    qwer;
	    while (1);
9   brace not indented correctly:
	case 'c':   if (cond)
			{
    Should align with "if" in case statement.
7   Allow aligning a closing ")" with the line above, instead of the matching
    "(": (Riehm) if (asdfasdf &&
			asdf
			)
9   "case xx: {", or in general: any { with text before it, a matching }
    should not line up with the {, but with the indent at that position.
    Add setting for K&R paren style?  Should be used for this:
	case xx: {
		    some_cmd;
	}
8   "int asdf,<CR>asdf;" should indent the second line more. (Zellner)
8   In C++ it's possible to have {} inside (): (Kirshna)
		func(
			new String[] {
			    "asdf",
			    "asdf"
			}
		    );
7   Separate "(0" option into inside/outside a function (Zellner):
	func(
	   int x)	// indent like "(4"
	{
	   if (a
	       && b)	// indent like "(0"
9   Wrong indent for continuation line with a string:
	void foo()
	{
	    x = f("s \
		asd\
		    tem");
		ff;
	}
    Also note that the "tem" line has an extra indent.  It appears that the
    brace matching doesn't work, because of the single " in the line.
9   Wrong indent for cino=(4, removing the (void) fixes it: (Zellner)
	(void) MyFancyFunction(
			       argument);
-   Make smartindenting configurable. Add 'sioptions', e.g. '#' setting the
    indent to 0 should be switched on/off.
7   Support ANSI style function header, with each argument on its own line.
-   "[p" and "]p" should use 'cindent' code if it's on (only for the first
    line).
-   Add option to 'cindent' to set indent for comments outside of {}?
-   Make a command to line up a comment after a code line with a previous
    comment after a code line.	Can 'cindent' do this automatically?
7   Add 'j' flag to 'formatoptions': Remove comment leader when joining lines.
-   formatting of struct/array inits:
    The lines used to initialize the struct or array above should not be
    considered 'continuation' lines just because the previous one does not end
    with ';'.  If you go back line by line I think it should be possible to
    tell the difference.  If you find a line that ends in ';', then it's OK to
    have continuation lines.  If you find a "{", and the character before it
    (not counting space & comments) is either ',' or '=', then there should
    not be continuation lines.	If the character before the "{" is another
    "{", then you have to check before that one too.
-   When 'cindent'ing a '}', showmatch is done before fixing the indent.  It
    looks better when the indent is fixed before the showmatch. (Webb)
-   Add option to make indenting work in comments too (for commented-out
    code), unless the line starts with "*".
-   Don't use 'cindent' when doing formatting with "gq"?
-   When formatting a comment after some text, insert the '*' for the new line
    (indent is correct if 'cindent' is set, but '*' doesn't get inserted).
-   For smartindent: When typing 'else' line it up with matching 'if'.
-   'smartindent': allow patterns in 'cinwords', for e.g. TeX files, where
    lines start with "\item".
-   Support this style of comments (with an option): (Brown)
	/* here is a comment that
	is just autoindented, and
	nothing else */
-   Add words to 'cinwords' to reduce the indent, e.g., "end" or "fi".
7   Use Tabs for the indent of starting lines, padd with spaces for
    continuation lines.  Allows changing 'tabstop' without messing up the
    indents.
    And/or: Add option to copy indent as-is, without changing spaces to tabs.


Java:
8   Can have {} constructs inside parens.  Include changes from Steve
    Odendahl?
8   Recognize "import java.util.Vector" and use $CLASSPATH to find files for
    "[i" commands and friends.


'comments':
7   When using "comments=fg:--", Vim inserts three spaces for a new line.
    When hitting a TAB, these spaces could be removed.
7   The 'n'esting flag doesn't do the indenting of the last (rightmost) item.
6   Make strings in 'comments' option a RE, to be able to match more
    complicated things. (Phillipps)  Use a special flag to indicate that a
    regexp is used.
8   Make the 'comments' option with "/* * */" lines only repeat the "*" line
    when there is a "/*" before it?  Or include this in 'cindent'?


Text objects:
8   Add test script for text object commands "aw", "iW", etc.
8   Add "gp" and "gP" commands: insert text and make sure there is a single
    space before it, unless at the start of the line, and after it, unless at
    the end of the line or befor a ".".
7   Add "g{" and "g}" to move to the first/last character of a paragraph
    (instead of the line just before/after a paragraph as with "{" and "}").
6   Ignore comment leaders for objects.  Make "das" work in reply-email.
5   Make it possible to use syntax group matches as a text object.  For
    example, define a "ccItem" group, then do "da<ccItem>" to delete one.
    Or, maybe just define "dai", delete-an-item, to delete the syntax item the
    cursor is on.


Select mode:
7   Alt-leftmouse starts block mode selection in MS Word.
7   Add Cmdline-select mode.  Like Select mode, but used on the command line.
    - Change gui_send_mouse_event() to pass on mouse events when 'mouse'
      contains 'C' or 'A'.
    - Catch mouse events in ex_getln.c.  Also shift-cursor, etc., like in
      normal_cmd().
    - remember start and end of selection in cmdline_info.
    - Typing text replaces the selection.


Visual mode:
-   When dragging the Visual selection with the mouse and 'scrolloff' is zero,
    behave like 'scrolloff' is one, so that the text scrolls when the pointer
    is in the top line.
8   In Visual block mode, "A" appends to lines that don't extend into the
    block, but padding is wrong (always two spaces).  Fix the padding.
9   With blockwise Visual mode, "A" works different than "I" when there are
    short lines.  Make them work the same way.  Also make it possible to add
    the text to short lines too, with padding where needed.
8   What is "R" supposed to do in Visual mode?
8   Make Visual mode local to the buffer.  Allow changing to another buffer.
    When starting a new Visual selection, remove the Visual selection in any
    other buffer. (Ron Aaron)
7   Support dragging the Visual area to drop it somewhere else. (Aaron)
7   With blockwise Visual mode and "c", "C", "I", "A", etc., allow the use of
    a <CR>.  The entered lines are repeated over the Visual area.
7   CTRL-V :s should substitute only in the block, not to whole lines. (David
    Young is working on this)
7   Filtering a block should only apply to the block, not to the whole lines.
    When the number of lines is increased, add lines. When decreased, padd with
    spaces or delete? Use ":`<,`>" on the command line.
8   After filtering the Visual area, make "gv" select the filtered text?
    Currently "gv" only selects a single line, not useful.
7   Don't move the cursor when scrolling?  Needed when the selection should
    stay the same.  Scroll to the cursor at any movement command.  With an
    option!
7   In Visual block mode, need to be able to define a corner on a position
    that doesn't have text?  Also: when using the mouse, be able to select
    part of a TAB.  Even more: Add a mode where the cursor can be on a screen
    position where there is no text.  When typing, add spaces to fill the gap.
    Other solution: Always use curswant, so that you can move the cursor to
    the right column, and then use up/down movements to select the line,
    without changing the column.
6   ":left" and ":right" should work in Visual block mode.
7   For Visual mode: Command to do a search for the string in the marked area.
    Only when less than two lines. Use "g/" and "g?".
7   CTRL-I and CTRL-O should work in Visual mode, but only jump to marks in the
    current buffer.
7   CTRL-A and CTRL-X should increase/decrease all numbers in the Visual area.
6   In non-Block mode, "I" should insert the same text in front of each line,
    before the first non-blank, "gI" in column 1.
6   In non-Block mode, "A" should append the same text after each line.
6   ":'<,'>source" should read the selected lines and ":source" them.
6   When in blockwise visual selection (CTRL-V), allow cursor to be placed
    right of the line. Could also allow cursor to be placed anywhere on a TAB
    or other special character.
6   Add commands to move selected text, without deselecting.


Quickfix:
8   Quickfix mode: Column number should be interpreted with an 8-character
    tabstop.


More advanced repeating commands:
-   Add "." command for visual mode: redo last visual command (e.g. ":fmt").
-   Add "." command after operator: repeat last command of same operator. E.g.
    "c." will repeat last change, also when "x" used since then (Webb).
    "y." will repeat last yank.
    "c2." will repeat the last but one change?
    Also: keep history of Normal mode commands, add command to list the history
    and/or pick an older command.
-   History stack for . command?  Use "g." command.


Mappings and Abbreviations:
8   To make a mapping work with a prepended "x to select a register, store the
    last _typed_ register name and access it with "&.
8   Add ":amap", like ":amenu".
8   Add ":cab!", abbreviations that only apply to Command-line mode and not to
    entering search strings.
8   Allow mapping of CTRL-@ (anywhere in the LHS).
8   Give a warning when using CTRL-C in the lhs of a mapping.  It will never
    (?) work.
8   Add a way to save a current mapping and restore it later.  Use a function
    that returns the mapping command to restore it: mapcmd()?  mapcheck() is
    not fool proof.  How to handle ambigious mappings?
7   Add <0x8f> (hex), <033> (octal) and <123> (decimal) to <> notation?
7   Allow mapping "Q" and "Q}" at the same time.  Need to put a flag with "Q",
    that it needs an extra character before it can match. See Vile 'maplonger'
    option.
7   When someone tries to unmap with a trailing space, and it fails, try
    unmapping without the trailing space.  Helps for ":unmap xx | unmap yy".
7   Make it possible to map 'wildchar', but only when it's a special character
    (like CTRL-E).  Currently it's only recognized when typed.  Useful for
    mapping a key to do something and then completion.
6   Context-sensitive abbreviations: Specify syntax group(s) in which the
    abbreviations are to be used.
-   Add mappings that take arguments.  Could work like the ":s" command.  For
    example, for a mouse escape sequence:
	:mapexp  <Esc>{\([0-9]*\),\([0-9]*\);	H\1j\2l
-   Add the possibility to enter mappings which are used whenever normal text
    could be entered.  E.g., for "f" command.  But not in Normal mode.  Sort
    of opposite of 'langmap'.  Use ":tmap" command?
-   Make it possible to include a <Nul> in the lhs and rhs of a mapping.
-   Add command to repeat a whole mapping ("." only repeats the last change in
    a mapping).  Also: Repeat a whole insert command, including any mappings
    that it included.  Sort-of automatic recording?
-   Make it possible to undo all the commands from a mapping, including a
    trailing unfinished command, e.g. for ":map K iX^[r".
-   Add an option to ":map" that makes it display the special keys in
    <> notation (e.g. <CR> instead of ^M).  Or just always do this?
-   Include an option (or flag to 'cpoptions') that makes errors in mappings
    not flush the rest of the mapping (like nvi does).
-   Use context sensitiveness of completion to switch abbreviations and
    mappings off for :unab and :unmap.
6   When using mappings in Insert mode, insert characters for incomplete
    mappings first, then remove them again when a mapping matches.  Avoids
    that characters that are the start of some mapping are not shown until you
    hit another character.
-   Add optional <Number> argument for mappings:
    :map <Number>q	     ^W^W<Number>G
    :map <Number>q<Number>t  ^W^W<Number1-1>G<Number2>l
    :map q<Char>	    :s/<Char>/\u\0/g
    Or implicit:
    :map q			<Register>d<Number>$
-   Add mappings for replace mode: ":rmap".  How do we then enter mappings for
    non-replace Insert mode?
-   Add separate mappings for Visual-character/block/line mode?
6   Alias for Normal mode commands, works like :substitute?  Would allow
    mappings with arguments.
-   Add 'mapstop' command, to stop recursive mappings.
-   List mappings that have a raw escape sequence both with the name of the key
    for that escape sequence (if there is one) and the sequence itself.
-   List mappings: Once with special keys listed as <>, once with meta chars as
    <M-a>, once with the byte values (octal?). Sort of "spell mapping" command?
-   When entering mappings: Add the possibility to enter meta keys like they
    are displayed, within <>: <M-a>, <~@> or <|a>.
-   Allow multiple arguments to :unmap.
-   Command to show keys that are not used and available for mapping
    ":freekeys".
-   Allow any character except white space in abbreviations lhs (Riehm).


Incsearch:
-   Add a limit to the number of lines that are searched for 'incsearch'?
-   When incsearch used and hitting return, no need to search again in many
    cases, saves a lot of time in big files. (Slootman wants to work on this?)
    When not using special characters, can continue search from the last match
    (or not at all, when there was no match).  See oldmail/webb/in.872.
-   With incsearch, use CTRL-N/CTRL-P to go to next/previous match, some other
    key to copy matched word to search pattern (Alexander Schmid).
-   How to make a "package java.util" cause all classes in the package to be
    searched?  Also for "import java.util.*". (Mark Brophy)


Searching:
8   Would it be possible to allow ":23,45/pat/flags" to search for "pat" in
    lines 23 to 45?  Or does this conflict with Ex range syntax?
8   Allow identical pairs in 'matchpairs'.  Restrict the search to the current
    line.
7   Allow longer pairs in 'matchpairs'.  Use ~/vim/macros/matchit.vim as an
    example.
8   Make it possible to define the character that "%" checks for in
    #if/#endif.  For nmake it's !if/!endif.
-   For "%" command: set hierarchy for which things include other things that
    should be ignored (like "*/" or "#endif" inside /* */).
    Also: use "%" to jump from start to end of syntax region and back.
    Alternative: use matchit.vim
8   "/:/e+1" gets stuck on a match at the end of the line.  Do we care?
8   A pattern like "\([^a]\+\)\+" takes an awful long time.  Recognize that
    the recursive "\+" is meaningless and optimize for it.
    This one is also very slow on "/* some comment */": "^\/\*\(.*[^/]\)*$".
7   Recognize "[a-z]", "[0-9]", etc. and replace them with the faster "\l" and
    "\d".
8   Flags that apply to the whole pattern.
    This works for all places where a regexp is used.
    Add "\q" to not store this pattern as the last search pattern?
8   Add an option not to use 'hlsearch' highlighting for ":s" and ":g"
    commands. (Kahn)  It would work like ":noh" is used after that command.
    Also: An extra flag to do this once, and a flag to keep the existing
    search pattern.
-   Add \%h{group-name}; to search for a specific highlight group.
    Add \%s{syntax-group}; to search for a specific syntax group.
-   Support Perl regexp.  Use PCRE (Perl Compatible RE) package. (Shade)
    Or translate the pattern to a Vim one.
    Don't switch on with an option for typed commands/mappings/functions, it's
    too confusing.  Use "\@@" in the pattern, to avoid incompatibilities.
7   Add POSIX regexp, like Nvi, with 'extended' option?  It's like very-magic.
-   Remember flags for backreferenced items, so that "*" can be used after it.
    Check with "\(\S\)\1\{3}". (Hemmerling)
-   Add flags to search command (also for ":s"?):
    i	ignore case
    I	use case
    p	use Perl regexp syntax (or POSIX?)
    v	use Vi regexp syntax
    f	forget pattern, don't keep it for "n" command
    F   remember pattern, keep it for "n" command
    Perl uses these too:
    e	evaluate the right side as an expression (Perl only)
    m	multiple line expression (we don't need it)
    o	compile only once (Perl only)
    s	single line expression (we don't need it)
    x	extended regexp (we don't need it)
    When used after ":g" command, backslash needed to avoid confusion with the
    following command.
    Add 'searchflags' for default flags (replaces 'gdefault').
-   Add command to display the last used substitute pattern and last used
    pattern. (Margo)  Maybe make it accessible through a register (like "/
    for search string)?
7   Use T-search algorithm, to speed up searching for strings without special
    characters.  See C't article, August 1997.
-   Add 'fuzzycase' option, so that case doesn't matter, and '-' and '_' are
    equivalent (for Unix filenames).
-   Add 'v' flag to search command: enter Visual mode, with the matching text
    as Visual area. (variation on idea from Bertin)
-   Searching: "/this//that/" should find "that" after "this".
-   Add global search commands: Instead of wrapping at the end of the buffer,
    they continue in another buffer. Use flag after search pattern:
    a	for the next file in the argument list
    f	for file in the buffer list
    w	for file edited in a window.
    e.g. "/pat/f". Then "n" and "N" work through files too. "f" flag also for
    ":s/pat/foo/f"??? Then when 'autowrite' and 'hidden' are both not set, ask
    before saving files: "Save modified buffer "/path/file"? (Yes/Hide/No
    Save-all/hide-All/Quit) ".
-   ":s/pat/foo/3": find 3rd match of "pat", like sed. (Thomas Koehler)
-   Special characters in patterns:
    Inside []:
    \012  octal character
    \0x1a hex character
    \0<BS> \0<Esc>: special character
7   When searching with 'n' give message when getting back where the search
    first started. Remember start of search in '/ mark.
7   Add option that scrolls screen to put cursor in middle of screen after
    search always/when off-screen/never.  And after a ":tag" command.  Maybe
    specify how many lines below the screen causes a redraw with the cursor in
    the middle (default would be half a screen, zero means always).
6   Support multiple search buffers, so macros can be made without side
    effects.
7   From xvim: Allow a newline in search patterns (also for :s, can delete
    newline).  Add BOW, EOW, NEWL, NLORANY, NLBUTANY, magic 'n' and 'r', etc.
    [not in xvim:] Add option to switch on matches crossing ONE line boundary.
7   Add ":iselect", a combination of ":ilist" and ":tselect". (Aaron)
    Also ":dselect".


Undo:
8   Make undo more memory-efficient: Compare text before and after change,
    only remember the lines that really changed.
7   Add an undo tree: When making a change, instead of clearing any future
    undo (thus redo) info, make a new branch.  How to navigate through the
    undo tree?
-   For u_save() include the column number. This can be used to set '[ and '].
    And in the future the undo can be made more efficient (Webb).
-   In out-of-memory situations: Free allocated space in undo, and reduce the
    number of undo levels (with confirmation).
-   Instead of [+], give the number of changes since the last write: [+123].
    When undoing to before the last write, change this to a negative number:
    [-99].
7   Make it possible to jump to the location of the last change.  Like doing
    "u" "CTRL-R". (Lange)  Keep a list of the 10 last changes or so. Use
    g_CTRL-O and g_CTRL-I?
-   With undo with simple line delete/insert: optimize screen updating.
-   When executing macro's: Save each line for undo only once.
-   Store undo info in a file that survives until the next edit.  Then it's
    possible to undo to before the current editing session.  Combined with
    viminfo?
-   When doing a global substitute, causing almost all lines to be changed,
    undo info becomes very big.  Put undo info in swap file??


Buffer list:
7   Command to execute a command in another buffer: ":inbuf {bufname} {cmd}".
    Also for other windows: ":inwin {winnr} {cmd}".  How to make sure that
    this works properly for all commands, and still be able to return to the
    current buffer/window?  E.g.: ":inbuf xxx only".
8   Add File.{recent_files} menu entries: Recently edited files.
8   Unix: Check all uses of fnamecmp() and fnamencmp() if they should check
    inode too.
7   Add another number for a buffer, which is visible for the user.  When
    creating a new buffer, use the lowest number not in use. (or the highest
    number in use plus one?)
7   Offer some buffer selection from the command line?  Like using ":ls" and
    asking for a buffer number. (Zachmann)
-   When starting to edit a file that is already in the buffer list, use the
    file name argument for the new short file name. (Webb)
-   Add an option to make ":bnext" and ":bprev" wrap around the end of the
    buffer list.  Also for ":next" and ":prev"?
7   Add argument to ":ls" which is a pattern for buffers to list.
    E.g. ":ls *.c". (Thompson)
7   Add expansion of buffer names, so that "*.c" is expanded to all buffer
    names.  Needed for ":bdel *.c", ":bunload *.c", etc.
8   Support for <afile> where a buffer name is expected.
8   Some commands don't use line numbers, but buffer numbers. '$'
    should then mean the number of the last buffer.  E.g.: "4,$bdel".
7   Add an option to mostly use slashes in file names.  Separately for
    internal use and for when executing an external program?


Swap (.swp) files:
8   If writing to the swap file fails, should try to open one in another
    directory from 'dir'.  Useful in case the file system is full and when
    there are short file name problems.
8   Also use the code to try using a short file name for the backup and swap
    file for the Win32 and Dos 32 bit versions.
8   When the edited file is a symlink, try to put the swap file in the same
    dir as the actual file. Adjust FullName().	Avoids editing the same file
    twice (e.g. when using quickfix).  Also try to make the name of the backup
    file the same as the actual file?
7   When using 64 bit inode numbers, also store the top 32 bits.  Add another
    field for this, using part of bo_fname[], to keep it compatible.
7   When editing a file on removable media, should put swap file somewhere
    else.  Use something like 'r' flag in 'viminfo'. 'diravoid'?
    Also: Be able to specify minimum disk space, skip directory when not
    enough room.
7   Add a configure check for which directory should be used: /tmp, /var/tmp
    or /var/preserve.
-   Add an option to create a swap file only when making the first change to
    the buffer.  (Liang)  Or only when the buffer is not read-only.
-   Add option to set "umask" for backup files and swap files (Antwerpen).
    'backupumask' and 'swapumask'?  Or 'umaskback' and 'umaskswap'?
-   When editing a readonly file, don't use a swap file but read parts from the
    original file.  Also do this when the file is huge (>'maxmem').  We do
    need to load the file once to count the number of lines?  Perhaps keep a
    cached list of which line is where.


Viminfo:
7   Can probably remove the code that checks for a writable viminfo file,
    because we now do the chown() for root, and others can't overwrite someone
    else's viminfo file.
8   Add argument to keep the list of buffers when Vim is started with a file
    name. (Schild)
8   Keep the last used directory of the file browser (File/Open menu).
8   Remember a list of last accessed files.  To be used in the
    "File.Open Recent" menu.  Default is to remember 10 files or so.
    Also remember which files have been read and written.  How to display
    this?
7   Also store the ". register (last inserted text).
7   Make it possible to store buffer names in viminfo file relative to some
    directory, to make them portable over a network. (Aaron)
6   Store a snapshot of the currently opened windows.  So that when quitting
    Vim, and then starting again (without a file name argument), you see the
    same files in the windows.  Use ":mksession" code?
-   Make marks present in .viminfo usable as file marks: Display a list of
    "last visited files" and select one to jump to.


Modelines:
8   Before trying to execute a modeline, check that it looks like one (valid
    option names).  If it's very wrong, silently ignore it.
    Ignore a line that starts with "Subject: ".
-   When an option value is coming from a modeline, do not carry it over to
    another edited file?  Would need to remember the value from before the
    modeline setting.
-   Allow setting a variable from a modeline?  Only allow using fixed strings,
    no function calls, to avoid a security problem.
-   Allow ":doauto BufRead x.cpp" in modelines, to execute autocommands for
    .cpp files.
-   Support the "abbreviate" command in modelines (Kearns).  Careful for
    characters after <Esc>, that is a security leak.
-   Add option setting to ask user if he wants to have the modelines executed
    or not.  Same for .exrc in local dir.


Options:
8   Make ":mksession" store buffer-specific options for the specific buffer.
8   With ":mksession" always store the 'sessionoptions' option, even when
    "options" isn't in it. (St-Amant)
8   When using ":mksession", also store a command to reset all options to
    their default value, before setting the options that are not at their
    default value.
8   Should ":mksession" restore the current directory when writing the
    session, or the directory where the session file is?  Probably need a word
    in 'sessionoptions' to make a choice:
    "curdir" (cd to current directory when session file was generated)
    "sessiondir" (cd to directory of session file)
    "nodir" (don't cd at all)
8   Add Edit.Settings menu with most often used options:
	line numbering on/off
	wrap on/off
	hlsearch on/off
	toolbar on/off
	scrollbars left, right, bottom on/off
	shiftwidth 2, 3, 4, 5, 6, 8
	expandtab on/off
8   Make "old" number options that really give a number of effects into string
    options that are a comma separated list.  The old number values should
    also be supported.
8   Add commands to save and restore an option, which also preserves the flag
    that marks if the option was set.  Useful to keep the effect of setting
    'compatible' after ":syntax on" has been used.
7   There is 'titleold', why is there no 'iconold'? (Chazelas)


External commands:
9   When filtering a buffer (e.g., to gunzip it) marks are changed when they
    shouldn't.  Add an option to switch of adjusting marks.  Use it for .gz
    files gunzipping and gzipping.
8   When filtering text, redirect stderr so that it can't mess up the screen
    and Vim doesn't need to redraw it.  Also for ":r !cmd".
4   Set separate shell for ":sh", piping "range!filter", reading text "r !ls"
    and writing text "w !wc". (Deutsche)  Allow arguments for fast start (e.g.
    -f).
4   Allow direct execution, without using a shell.
4   Run an external command in the background.  But how about I/O in the GUI?
    Careful: don't turn Vim into a shell!
4   Add feature to disable using a shell or external commands.


Multiple Windows:
6   Add an option to resize the shell when splitting and/or closing a window.
    ":vsp" would make the shell wider by as many columns as needed for the new
    window.  Specify a maximum size (or use the screen size). ":close" would
    shrink the shell by as many columns as come available. (Demirel)
7   When starting Vim several times, instanciate a Vim server, that allows
    communication between the different Vims.  Feels like one Vim running with
    multiple top-level windows.  Esp. useful when Vim is started from an IDE
    too.  Requires some form of inter process communication.
7   Run Vim as a server, and let other started Vims send an edit command to
    the server.  Consider patch from Brent Verner to add sockets interface?
    ~/vim/patches/verner_socket.tgz
-   Support a connection to an external viewer.  Could call the viewer
    automatically after some seconds of non-activity, or with a command.
    Allow some way of reporting scrolling and cursor positioning in the viewer
    to Vim, so that the link between the viewed and edited text can be made.


Marks:
8   Add a command to jump to a mark and make the motion inclusive. g'm and g`m?
8   When deleting lines, don't delete uppercase marks in them.  Move the mark
    to the nearest line.
8   The '" mark is set to the first line, even when doing ":next" a few times.
    Only set the '" mark when the cursor was really moved in a file.
8   Make `` and '', which would position the new cursor position in the middle
    of the window, restore the old topline (or relative position) from when
    the mark was set.
7   Make a list of file marks in a separate window.  For listing all buffers,
    matching tags, errors, etc.  Normal commands to move around.  Add commands
    to jump to the mark (in current window or new window).  Start it with
    ":browse cmd"?
6   Add a menu that lists the Marks like ":marks". (Amerige)
7   For ":jumps", ":tags" and ":marks", for not loaded buffers, remember the
    text at the mark.  Highlight the column with the mark.
7   Highlight each mark in some way (With "Mark" highlight group).
    Or display marks in a separate column, like 'number' does.
7   Use d"m to delete rectangular area from cursor to mark m (like Vile's \m
    command).
7   Try to keep marks in the same position when:
    - replacing with a line break, like in ":s/pat/^M/", move marks after the
      line break column to the next line. (Acevedo)
    - filtering lines, try to keep the marks in the filtered lines. Need to
      move some marks if the number of lines decreases.
    - changing text, e.g. when formatting with "gq".
    - inserting/deleting characters in a line.
5   Include marks for start/end of the current word and section.  Useful in
    mappings.


Digraphs:
-   Make it possible to enter "r<C-E>" and "r<C-Y>" (get character from line
    below/above).
-   Use digraph table to tell Vim about the collating sequence of special
    characters?
-   Add command to remove (all) digraphs. (Brown)
7   Support different sets of digraphs (depending on the character set?).  At
    least Latin1/Unicode, Latin-2, MS-DOS (esp. for Win32).


Writing files:
-   In vim_rename(), should lock "from" file when deleting "to" file for
    systems other than Amiga.  Avoids problems with unexpected longname to
    shortname conversion.
8   write mch_isdevice() for Amiga, Mac, VMS, etc.
8   When appending to a file, Vim should also make a backup and a 'patchmode'
    file.
6   Add an option to write a new, numbered, backup file each time.  Like
    'patchmode', e.g., 'backupmode'.
6   Make it possible to write 'patchmode' files to a different directory.
    E.g., ":set patchmode=~/backups/*.orig". (Thomas)
6   Add an option to prepend something to the backup file name.  E.g., "#".
    Or maybe allow a function to modify the backup file name?
8   Only make a backup when overwriting a file for the first time. Avoids
    loosing the original when writing twice. (Slootman)
7   On non-Unix machines, also overwrite the original file in some situations
    (file system full, it's a link on an NFS partition).
7   When editing a file, check that it has been change outside of Vim more
    often, not only when writing over it.  E.g., at the time the swap file is
    flushed.  Or every ten seconds or so (use the time of day, check it before
    waiting for a character to be typed).
8   When a file was changed since editing started, show this in the status
    line of the window, like "[time]".
    Make it easier to reload all outdated files that don't have changes.
    Automatic and/or with a command.


Substitute:
-   :s///p prints the line after a substitution.
-   With :s///c replace \&, ~, etc. when showing the replacement pattern.
8   With :s///c allow scrolling horizontally when 'nowrap' is effective.
    Also allow a count before the scrolling keys.
-   Add number option to ":s//2": replace second occurrence of string? Or:
    :s///N substitutes N times.
-   Add answers to ":substitute" with 'c' flag, used in a ":global", e.g.:
    ":g/pat1/s/pat2/pat3/cg": 'A' do all remaining replacements, 'Q' don't do
    any replacements.
7   Substitute in a block of text.  Use {line}.{column} notation in an Ex
    range, e.g.: ":1.3,$.5s" means to substitute from line 1 column 3 to the
    last line column 5.


Mouse support:
8   Add 'mouse' flag, which sets a behavior like Visual mode, but automatic
    yanking at the button-up event.  Or like Select mode, but typing gets you
    out of Select mode, instead of replacing the text. (Bhaskar)
7   Checkout sysmouse() for FreeBSD console mouse support.
-   Implement mouse support for the Amiga console.
-   Using right mouse button to extend a blockwise selection should attach to
    the nearest corner of the rectangle (four possible corners).
-   Precede mouse click by a number to simulate double clicks?!?
-   When mouse click after 'r' command, get character that was pointed to.


Crypt:
8   Also crypt the swapfile, each block separately.  Change mf_write() and
    mf_read().  How to get b_p_key to these functions?


Argument list:
6   Add command to put all filenames from the tag files in the argument list.
    When given an argument, only use the files where that argument matches
    (like `grep -l ident`) and jump to the first match.
6   Add command to form an args list from all the buffers?


Registers:
8   Don't display empty registers with ":display". (Etienne)
-   When appending to a register, also report the total resulting number of
    lines.  Or just say "99 more lines yanked", add the "more".
-   When inserting a register in Insert mode with CTRL-R, don't insert comment
    leader when line wraps?
-   The ":@r" commands should take a range and execute the register for each
    line in the range.
-   Add "P" command to insert contents of unnamed register, move selected text
	to position of previous deleted (to swap foo and bar in " + foo")
8   Make "/ register writable. (Maxi)
    How to take care of the flags (offset, magic)?
7   Add ! register, for shell commands. (patch from Grenie)


Various improvements:
8   Allow using "**" as a wildcard in commands like ":next" and ":args".
7   Add a message area for the user.  Set some option to reserve space (above
    the command line?).  Use an ":echouser" command to display the message
    (truncated to fit in the space).
7   Add %s to 'keywordprg': replace with word under the cursor. (Zellner)
8   Support printing on Unix.  Can use "lpansi.c" as an example. (Bookout)
8   Add put command that replaces the text under it.  Esp. for blockwise
    Visual mode.
7   Enhance termreponse stuff: Add t_CV(?): pattern of term response, use
    regexp: "\e\[[>?][0-9;]*c", but only check just after sending t_RV.
7   Add "g|" command: move to N'th column from the left margin (after wrapping
    and applying 'leftcol').  Works as "|" like what "g0" is to "0".
7   Add patch from Wall for this one ( ~/Mail/oldmail/wall/in.00019 ):
    'flipcase' variable: upper/lower case pairs.
    Insert comma's between pairs and allow a range, make it look like
    'isfname'.  E.g. ":set flipcase=a-zA-Z,xX,23-33:143-153".  The colon to
    separate the from and to part is optional.
7   Support setting 'euqalprg' to a user function name.
8   Add cursor-column highlighting.  Enable it with 'cursorcolumn' option, set
    highlighting with "CursorColumn" group.  Useful for aligning text.
    Also cursor-row highlighting.
7   Highlight the characters after the end-of-line differently.
7   When 'whichwrap' contains "l", "$dl" should join lines?
6   Include the ruby interface?
7   Open a server socket (with an option for IP/port nr) to allow remote
    control.  Optionally with a password to restrict access.
    Use the Simple Sockets Library? (Campbell)
    Same sample code (brent verner): http://linux1.org/misc/vim_socket.tar.bz2
8   Include a connection to an external program through a pipe?  See patches
    from Felbinger for a mathematica inteface.
    Or use emacs server kind of thing?
8   Add an argument to configure to use $CFLAGS and not modify it? (Mooney)
8   Enabling features is a mix of configure arguments and defines in
    feature.h.  How to make this consistent?  Feature.h is required for
    non-unix systems.  Perhaps let configure define CONF_XXX, and use #ifdef
    CONF_XXX in feature.h?  Then what should min-features and max-features do?
8   Add "g^E" and "g^Y", to scroll a screen-full line up and down.
6   Add ":timer" command, to set a command to be executed at a certain
    interval, or once after some time has elapsed. (Aaron)
8   Add ":confirm" handling in open_exfile(), for when file already exists.
8   Use confirm/dialog stuff to ask the user, when a file has changed outside
    of Vim, if he wants to reload it.  Triggered when focus gained, after
    shell command, when entering another buffer, etc..
    Also do this when editing a new file, and another application creates
    the file before doing ":w" in Vim.
    Also check if the file protection has changed.  When checking a file into
    RCS it is made read-only, when checking out it is made read-write.
8   When quitting with changed files, make the dialog list the changed file
    and allow "write all", "discard all", "write some".  The last one would
    then ask "write" or "discard" for each changed file.  Patch in HierAssist
    does something like this. (Shah)
7   Use growarray for replace stack.
7   Have a look at viH (Hellenic or Greek version of Vim).  But a solution
    outside of Vim might be satisfactory (Haritsis).
3   Make "2d%" work like "d%d%" instead of "d2%"?
8   Make "more" prompt accept command characters, like "hit-enter" prompt?
    Or extend it with more commands, like "less": 'b' for back, 'j' for one
    line down, etc.
8   For the "--more--" prompt, support the 'b'ack command for more commands.
7   "g CTRL-O" jumps back to last used buffer.	Skip CTRL-O jumps in the same
    buffer.  Make jumplist remember the last ten accessed buffers?
-   Keep a list of most recently used files for each window, use "[o" to go
    back (older file) and "]n" to go forward (newer file) (like ^O and ^I for
    jumps) (Webb). Use ":files" and ":ls" to list the files in history order.
7   Add a history of recently accessed buffer.	Maybe make "2 CTRL-^" jump to
    the 2nd previously visited buffer, "3 CTRL-^" to the third, etc.  Or use
    "3 g CTRL-^" for this?
7   Add an option to set the width of the 'number' column.  Eight positions is
    often more than needed.  Or adjust the width to the length of the file?
-   Add code to disable the CAPS key when going from Insert to Normal mode.
-   Set date/protection/etc. of the patchfile the same as the original file.
-   Use growarray for termcodes[] in term.c
-   Add <window-99>, like <cword> but use filename of 99'th window.
-   Make a set of operations on list of names: expand wildcards, replace home
    dir, append a string, delete a string, etc.
-   Remove mktemp() and use tmpname() only?  Ctags does this.
-   When replacing environment variables, and there is one that is not set,
    turn it into an empty string?  Only when expanding options? (Hiebert)
-   Option to set command to be executed instead of producing a beep (e.g. to
    call "play newbeep.au").
-   Add option to show the current function name in the status line.  More or
    less what you find with "[[k", like how 'cindent' recognizes a function.
    (Bhatt).
-   "[r" and "]r": like "p" and "P", but replace instead of insert (esp. for
    blockwise registers).
-   Add 'timecheck' option, on by default.  Makes it possible to switch off the
    timestamp warning and question. (Dodt).
-   Add an option to set the time after which Vim should check the timestamps
    of the files.  Only check when an event occurs (e.g., character typed,
    mouse moved).  Useful for non-GUI versions where keyboard focus isn't
    noticable.
9   When using ":w <fname>" it's possible that this file is loaded in another
    buffer.  Give a warning right away, don't wait for a shell command.
-   Make 'smartcase' work even though 'ic' isn't set (Webb).
7   When formatting text, allow to break the line at a number of characters.
    Use an option for this: 'breakchars'?  Useful for formatting Fortran code.
-   Add flag to 'formatoptions' to be able to format book-style paragraphs
    (first line of paragraph has larger indent, no empty lines between
    paragraphs).  Complements the '2' flag.  Use '>' flag when larger indent
    starts a new paragraph, use '<' flag when smaller indent starts a new
    paragraph.	Both start a new paragraph on any indent change.
8   Allow using a trailing space to signal a paragraph that continues on the
    next line.  Can be used for continuous formatting.  Could use 'autoformat'
    option, which specifies a regexp which triggers auto-formatting (for one
    line). ":set autoformat=\\s$".
-   Be able to redefine where a sentence stops.  Use a regexp pattern?
-   Be able to redefine where a paragraph starts.  For "[[" where the '{' is
    not in column 1.
8   ":cd": echo the new current directory.
6   Add ":cdprev": go back to the previous directory.  Need to remember a
    stack of previous directories.  We also need ":cdnext".
7   Should ":cd" for MS-DOS go to $HOME, when it's defined?
-   Make "gq<CR>" work on the last line in the file.  Maybe for every operator?
8   findmatchlimit() should be able to skip comments.  Solves problem of
    matching the '{' in /* if (foo) { */ (Fiveash)
-   findmatch() should be adjusted for Lisp.  See remark at get_lisp_indent().
-   Add more redirecting of Ex commands:
	:redir @> register  (append)
	:redir #  bufname
	:redir #> bufname   (append)
	:redir =  variable
	:redir => variable  (append)
8   ":redir >$HOME/xxx" should work: expand file name argument of ":redir".
-   Setting of options, specifically for a buffer or window, with
    ":set window.option" or ":set buffer.option=val".  Or use ":buffer.set".
    Also: "buffer.map <F1> quit".
-   Add :delcr command:
			    *:delcr*
     :[range]delcr[!]	Check [range] lines (default: whole buffer) for lines
			ending in <CR>.  If all lines end in <CR>, or [!] is
			used, remove the <CR> at the end of lines in [range].
			A CTRL-Z at the end of the file is removed.  If
			[range] is omitted, or it is the whole file, and all
			lines end in <CR> 'textmode' is set.  {not in Vi}
-   Should integrate addstar() and file_pat_to_reg_pat().
-   When working over a serial line with 7 bit characters, remove meta
    characters from 'isprint'.
-   Use fchdir() in init_homedir(), like in FullName().
-   In win_update(), when the GUI is active, always use the scrolling area.
    Avoid that the last status line is deleted and needs to be redrawn.
-   That "cTx" fails when the cursor is just after 'x' is Vi compatible, but
    may not be what you expect.  Add a flag in 'cpoptions' for this?  More
    general: Add an option to allow "c" to work with a null motion.
-   Give better error messages by using errno (strerror()).
-   Give "Usage:" error message when command used with wrong arguments (like
    Nvi).
-   Make 'restorescreen' option also work for xterm (and others), replaces the
    SAVE_XTERM_SCREEN define.
7   Support for ":winpos" In xterm: report the current window position.
-   Give warning message when using ":set t_xx=asdf" for a termcap code that
    Vim doesn't know about.  Add flag in 'shortmess'?
6   Add ":che <file>", list all the include paths which lead to this file.
-   For a commandline that has several commands (:s, :d, etc.) summarize the
    changes all together instead of for each command (e.g. for the rot13
    macro).
-   Add command like "[I" that also shows the tree of included files.
-   Add command like ":ts" that shows the output of "[I" and asks for a match
    to jump to. (Zellner)
-   ":set sm^L" results in ":set s", because short names of options are also
    expanded.  Is there a better way to do this?
-   Add ":@!" command, to ":@" like what ":source!" is to ":source".
8   Add ":@:!": repeat last command with forceit set.
-   Should be possible to write to a device, e.g. ":w! /dev/null".
-   Add 't_normal': Used whenever t_me, t_se, t_ue or t_Zr is empty.
-   ":cab map test ^V| je", ":cunab map" doesn't work.	This is vi compatible!
-   CTRL-W CTRL-E and CTRL-W CTRL-Y should move the current window up or down
    if it is not the first or last window.
-   Include-file-search commands should look in the loaded buffer of a file (if
    there is one) instead of the file itself.
7   Change 'nrformats' to include the leader for each format.  Example:
	nrformats=hex:$,binary:b,octal:0
    Add setting of 'nrformats' to syntax files.
-   'path' can become very long, don't use NameBuff for expansion.
-   When unhiding a hidden buffer, put the same line at top of the window as
    the one before hiding it. Or: keep the same relative cursor position (so
    many percent down the windows).
-   Make it possible for the 'showbreak' to be displayed at the end of the
    line.  Use a comma to separate the part at the end and the start of the
    line?  Highlight the linebreak characters, add flag in 'highlight'.
-   Some string options should be expanded if they have wildcards, e.g.
    'dictionary' when it is "*.h".
-   Use a specific type for number and boolean options, making it possible to
    change it for specific machines (e.g. when a long is 64 bit).
-   Add option for <Insert> in replace mode going to normal mode. (Nugent)
-   Add a next/previous possibility to "[^I" and friends.
-   Add possibility to change the HOME directory.  Use the directory from the
    passwd file? (Antwerpen)
-   When doing "[^I" or "[^D" add position to tag stack.
-   Add command to put current position to tag stack: ":tpush".
8   Add commands to push and pop all or individual options. ":setpush tw",
    ":setpop tw", ":setpush all".  Maybe pushing/popping all options is
    sufficient.  ":setflush" resets the option stack?
    How to handle an aborted mapping?  Remember position in tag stack when
    mapping starts, restore it when an error aborts the mapping?
-   Use a builtin grep command for ":grep"?  Makes it possible to add the
    column number.
-   Change ":fixdel" into option 'fixdel', t_del will be adjusted each time
    t_bs is set? (Webb)
-   "gc": goto character, move absolute character positions forward, also
    counting newlines. "gC" goes backwards (Weigert).
-   When doing CTRL-^, redraw buffer with the same topline (Demirel). Store
    cursor row and window height to redraw cursor at same percentage of window
    (Webb).
-   Besides remembering the last used line number of a file, also remember the
    column. Use it with CTRL-^ et. al.
-   When a window resizes, the line with the cursor should stay at the same
    percentage from the start of the window as it was before.
-   Check for non-digits when setting a number option (careful when entering
    hex codes like 0xff).
-   Add option to make "." redo the "@r" command, instead of the last command
    executed by it.  Also to make "." redo the whole mapping.  Basically: redo
    the last TYPED command.
-   Support URL links for ^X^F in Insert mode, like for "gf".
-   Add 'wwwpath', used like 'path' for when "gf" used on an URL?
-   Support %name% expansion for "gf" on Windows.
-   When finding an URL or file name, and it doesn't exist, try removing a
    trailing '.'.
-   Add ":path" command modifier.  Should work for every command that takes a
    file name argument, to search for the file name in 'path'.	Use
    find_file_in_path().
-   Highlight control characters on the screen: Shows the difference between
    CTRL-X and "^" followed by "X" (Colon).
-   Integrate parsing of cmdline command and parsing for expansion.
-   Create a program that can translate a .swp file from any machine into a
    form usable by Vim on the current machine.
-   Add ":noro" command: Reset 'ro' flag for all buffers, except ones that have
    a readonly file. ":noro!" will reset all 'ro' flags.
-   Add a variant of CTRL-V that stops interpretation of more than one
    character.	For entering mappings on the command line where a key contains
    several special characters, e.g. a trailing newline.
-   Add regex for 'paragraphs' and 'sections': 'parare' and 'sectre'. Combine
    the two into a regex for searching. (Ned Konz)
-   Make '2' option in 'formatoptions' also work inside comments.
-   Add 's' flag to 'formatoptions': Do not break when inside a string. (Dodt)
-   Add flag to 'formatoptions' to recognize the change of indent as the start
    of a new paragraph (for paragraphs without separating empty line, but extra
    indent for the new paragraph) (Leitner).
-   When window size changed (with the mouse) and made too small, set it back
    to the minimal size.
-   Add "]>" and "[<", shift comment at end of line (command;  /* comment */).
-   Should not call cursorcmd() for each vgetc() in getcmdline().
-   ":split file1 file2" adds two more windows (Webb).
-   Don't give message "Incomplete last line" when editing binary file.
-   Add ":a", ":i" for preloading of named buffers.
-   Allow autowrite when doing ":e file" (with an option 'eaw').
-   Allow a "+command" argument before each file name in the Vim command line:
    "vim +123 file1 +234 file2 +345 file3". ???
-   When entering text, keep other windows on same buffer updated (when a line
    entered)?
-   Check out how screen does output optimizing.  Apparently this is possible
    as an output filter.
-   In dosub() regexec is called twice for the same line. Try to avoid this.
-   Window updating from memline.c: insert/delete/replace line.
-   Optimize ml_append() for speed, esp. for reading a file.
-   V..c should keep indent when 'ai' is set, just like [count]cc.
-   Updatescript() can be done faster with a string instead of a char.
-   Screen updating is inefficient with CTRL-F and CTRL-B when there are long
    lines.
-   Uppercase characters in ex commands can be made lowercase?
8   Add option to show characters in text not as "|A" but as decimal ("^129"),
    hex ("\x81") or octal ("\201") or meta (M-x).  Nvi has the 'octal' option
    to switch from hex to octal.  Vile can show unprintable characters in hex
    or in octal.
7   Tighter integration with xxd to edit binary files.  Make it more
    easy/obvious to use.  Command line argument?
-   How does vi detect whether a filter has messed up the screen? Check source.
    After ":w !command" a wait_return?
-   Improve screen updating code for doput() (use s_ins()).
-   With 'p' command on last line: scroll screen up (also for terminals without
    insert line command).
-   Use insert/delete char when terminal supports it.
-   Optimize screen redraw for slow terminals.
-   Optimize "dw" for long row of spaces (say, 30000).
-   Add "-d null" for editing from a script file without displaying.
-   In Insert mode: Remember the characters that were removed with backspace
    and re-insert them one at a time with <key1>, all together with <key2>.
-   Amiga: Add possibility to set a keymap. The code in amiga.c does not work
    yet.
-   Implement 'redraw' option.
-   Add special code to 'sections' option to define something else but '{' or
    '}' as the start of a section (e.g. one shiftwidth to the right).
-   Add 'indent' option: Always use this amount of indent when starting a new
    line and when formatting text.
-   Use pipes for filtering on Unix.  Requires using fork() to be able to read
    and write at the same time, or some select() mechanism.
7   Allow using Vim in a pipe: "ls | vim -u xxx.vim - | yyy".  Only needs
    implementing ":w" to stdout in the buffer that was read from stdin.
8   Allow opening an unnamed buffer with ":e !cmd" and ":sp !cmd".  Vile can
    do it.
-   Allow for +command and -option on any position in argv[].
-   Add commands like ]] and [[ that do not include the line jumped to.
-   When :unab without matching "from" part and several matching "to" parts,
    delete the entry that was used last, instead of the first in the list.
-   Add text justification option.
-   Set boolean options on/off with ":set paste=off", ":set paste=on".
-   After "inv"ing an option show the value: ":set invpaste" gives "paste is
    off".
-   Check handling of CTRL-V and '\' for ":" commands that do not have TRLBAR.
-   When a file cannot be opened but does exist, give error message.
-   Amiga: When 'r' protection bit is not set, file can still be opened but
    gives read errors. Check protection before opening.
-   When writing check for file exists but no permission, "Permission denied".
-   If file does not exists, check if directory exists.
-   MSDOS: although t_cv and t_ci are not set, do invert char under cursor.
-   Settings edit mode: make file with ":set opt=xx", edit it, parse it as ex
    commands.
-   ":set -w all": list one option per line.
-   Amiga: test for 'w' flag when reading a file.
-   :table command (Webb)
-   Add new operator: clear, make area white (replace with spaces): "g ".
-   Make it possible for a user to define a new operator.  Implementation with
    internal scripting language or Perl?
-   Add command to ":read" a file at a certain column (blockwise read?).
-   Add 'resizecmd' option: vi command to be executed when window is resized.
-   Add sort of replace mode where case is taken from the old text (Goldfarb).
-   Allow multiple arguments for ":read", read all the files.
-   Support for tabs in specific columns: ":set tabcol=8,20,34,56" (Demirel).
-   Add 'searchdir' option: Directories to search for file name being edited
    (Demirel).
-   Modifier for the put command: Change to linewise, charwise, blockwise, etc.
-   Add commands for saving and restoring options ":set save" "set restore",
    for use in macro's and the like.
-   Keep output from listings in a window, so you can have a look at it while
    working in another window. Put cmdline in a separate window?
-   Add possibility to put output of ex commands in a buffer or file, e.g. for
    ":set all".  ":r :set all"?
-   'edit' option: When off changing the buffer is not possible (Really
    read-only mode).
-   When the 'equalalways' option is set, creating a new window should not
    result in windows to become bigger. Deleting a window should not result in
    a window to become smaller (Webb).
-   When resizing the whole Vim window, the windows inside should be resized
    proportionally (Webb).
-   Include options directly in option table, no indirect pointers. Use
    mkopttab to make option table?
-   When doing ":w dir", where "dir" is a directory name, write the current
    file into that directory, with the current file name (without the path)?
-   Support for 'dictionary's that are sorted, makes access a lot faster
    (Haritsis).
-   Add "^Vrx" on the command line, replace with contents of register x. Used
    instead of CTRL-R to make repeating possible. (Marinichev)
-   Add "^Vb" on the command line, replace with word before or under the
    cursor?
-   Option to make a .swp file only when a change is made (Templeton).
-   Support mapping for replace mode and "r" command (Vi doesn't do this)?
5   Add 'ignorefilecase' option: Ignore case when expanding file names.
    ":e ma<Tab>" would also find "Makefile" on Unix.


From Elvis:
-   Use "instman.sh" to install manpages?
-   Add ":alias" command.
-   fontchanges recognized "\\fB" etc.
-   Search patterns:
      \@	match word under cursor.
    but do:
      \@w	match the word under the cursor?
      \@W	match the WORD under the cursor?
8   ":window" command:
    :win +	next window (up)
    :win ++	idem, wrapping
    :win -	previous window (down)
    :win --	idem, wrapping
    :win nr	to window number "nr"
    :win name	to window editing buffer "name"
7   ":cc" compiles a single file (default: current one).  'ccprg'   option is
    program to use with ":cc".  Use ":compile" instead of ":cc"?


From Nvi:
-   'searchincr' option, alias for 'incsearch'?
-   'leftright' option, alias for 'nowrap'?
-   Have a look at "vi/doc/vi.chart", for Nvi specialities.
8   Add 'keytime', time in 1/10 sec for mapping timeout?
-   Add 'filec' option as an alternative for 'wildchar'.
6   Support Nvi command names as an alias:
    :bg		    :hide
    :fg	fname	    :buf fname (with 'hidden' set?)
    :dis b	    :ls
    :Edit fname	    :split fname
    :Fg fname	    :sbuf fname (with 'hidden' set?)
    :Next	    :snext (can't do this, already use :Next)
    :Previous	    :sprevious
    :Tag	    :stag


From xvi:
-   CTRL-_ : swap 8th bit of character.
-   Add egrep-like regex type, like xvi (Ned Konz) or Perl (Emmanuel Mogenet)


From vile:
-   When horizontal scrolling, use '<' and '>' for lines continuing outside of
    window.
-   Support putting .swp files in /tmp: Command in rc.local to move .swp files
    from /tmp to some directory before deleting files.


Far future and "big" extensions:
-   Make it possible to run Vim inside a window of another program.  For
    Xwindows this can be done with XReparentWindow().
-   Add a way of scrolling that leaves the cursor where it is.  Especially
    when using the scrollbar.  Typing a cursor-movement command scrolls back
    to where the cursor is.
-   Make it easy to setup Vim for groups of users: novice vi users, novice
    Vim users, C programmers, xterm users, GUI users,...
-   Add a mode to only view text.  Like Less, but with syntax highlighting
    etc.
-   Change layout of blocks in swap file: Text at the start, with '\n' in
    between lines (just load the file without changes, except for Mac).
    Indexes for lines are from the end of the block backwards.  It's the
    current layout mirrored.
-   Make it possible to edit a register, in a window, like a buffer.
-   Add stuff to syntax highlighting to change the text (upper-case keywords,
    set indent, define other highlighting, etc.).
-   Mode to keep C-code formatted all the time (sort of on-line indent).
-   Several top-level windows in one Vim session.  Be able to use a different
    font in each top-level window.
-   Allow editing beyond end of line, just like there are all spaces. Switch
    this on with an option or special Insert mode command. Also allow editing
    above start and below end of buffer.
-   Smart cut/paste: recognize words and adjust spaces before/after them.
-   Mode to keep text formatted while inserting/deleting.  Use soft/hard
    returns with an option to switch this off. (CR-LF can be used for Unix as
    a soft return).
-   Add column numbers to ":" commands ":line1,line2[col1,col2]cmd".  Block
    can be selected with CTRL-V.  Allow '$' (end of line) for col2.
-   Add open mode, use it when terminal has no cursor positioning.
-   Special "drawing mode": a line is drawn where the cursor is moved to.
    Backspace deletes along the line (from jvim).
-   Perform commands on multiple windows (:W%s/foo/bar/g), multiple arguments
    (:A) or multiple buffers (:B). Implement ":Bset", set option in all
    buffers.  Also ":Wset", set in all windows, ":Aset, set in all arguments
    and ":Tset", set in all files mentioned in the tags file.  Add buffer/arg
    range, like in ":2,5B%s/..." (do we really need this???) Add search
    string: "B/*.c/%s/.."?  Or ":F/*.c/%s/.."?
-   Support for underlining (underscore-BS-char), bold (char-BS-char) and other
    standout modes switched on/off with , 'overstrike' option (Reiter).
-   Add vertical mode (Paul Jury, Demirel): "5vdw" deletes a word in five
    lines, "3vitextESC" will insert "text" in three lines, etc..
4   Recognize l, #, p as 'flags' to EX commands:
    :g/RE/#l shall print lines with line numbers and in list format.
    :g/RE/dp shall print lines that are deleted.
    POSIX: Commands where flags shall apply to all lines written: list,
    number, open, print, substitute, visual, &, z. For other commands, flags
    shall apply to the current line after the command completes.  Examples:
    :7,10j #l Join the lines 7-10 and print the result in list

-------------------- *votes-for-changes* -----------------------

In November 1998 an inquiry was held to allow Vim users to vote for changes to
Vim.  Each person was allowed to give 10 positive and 5 negative points to a
list of items.  Below is the result.  This indicates the desire of users for
certain changes.  This will be taken into account when deciding what to do
next from the huge list above.
