05:19:33 <crc> I added a bunch of combinators from joy and factor to the repo; now to see if they are actually useful anywhere :)
07:44:00 <docl> cool :)
07:46:35 <crc> I've been doing a lot of cleanup to the code today. quotes + combinators are nice
07:46:58 <docl> neat
07:47:05 <docl> which are combinators?
07:48:37 <crc> dip, sip, curry, take, tack, bi, tri, bi*, tri*, times, -times, +times, until, forever, choose, ifTrue, ifFalse
07:51:01 <foucist> why do i get the feeling that dip/sip/curry are names that were picked for their cuteness, not for their readability? :P
07:51:25 <crc> foucist: names were taken from other languages using them; in this case joy and factor
07:51:42 <foucist> ok, what does curry do?
07:51:46 <foucist> or dip?
07:52:03 <crc> read the docs :)
07:53:05 <crc> curry returns a new quote, binding a data element and another quote together.
07:53:19 <crc> e.g.,   5 &1+ curry   ==   [ 5 1+ ]
07:53:38 <crc> dip runs a quote with a number temporarily removed from the data stack.
07:54:05 <crc> e.g.,  3 5 &1+ dip   ==   3 5 push 1+ pop
09:18:03 <crc> foucist: any ideas for better names?
10:04:39 <foucist> what's the quote about, and why ampersand instead of an actual quote
10:04:46 <foucist> like '1+ or "1+
10:05:02 <foucist> hmm
10:05:32 <foucist> so [ 1+ ] == &1+  ?
10:06:33 <foucist> i guess << could be a good name for curry
10:06:55 <foucist> in ruby it's like [ 1 ] << 2   #==> [ 1, 2 ]
10:07:57 <foucist> maybe not though
10:08:12 <foucist> well << also means something else in forth iirc
10:08:25 <docl> lshift?
10:08:27 <foucist> yeah
12:03:00 --- join: roarde (~roarde@pdpc/supporter/active/sixforty) joined #retro
12:40:50 <crc> a quote is an anoymous function; &1+ gives an address for 1+, which is functionally the same as saying [ 1+ ] or ' 1+
12:41:01 <crc> << is used for left shift
12:41:38 * crc just got home from work
12:47:13 <docl> foucist: the ' prefix is used for getting a character, so '1 would be the ascii code for 1.
12:49:26 <crc> ' for ascii characters, # for decimal, $ for hex, % for binary, " for strings, & for returning addresses, + for incrementing a variable, - for decrementing a variable, @ to fetch a value, and ! to store a value. I think that covers everything in the main dictionary
12:49:56 <crc> there are also > and < in the linkedList' vocabulary, for adding and removing values from a linked list
13:49:32 --- quit: roarde (Quit: Leaving.)
17:40:37 <crc> { } namespaces are gone; {{ }} now serve to replace them if used without ---reveal---
19:10:41 <docl> that makes sense. we can use { } for other things now :)
19:10:52 <crc> yup. this was long overdue.
19:11:28 <crc> 10.7.3 will have the new functionality in {{ }}, but still has { } for compatibility. now flagged as depreciated in the docs, and gone from the repo
