07:53:28 <Zarutian> in an Forth-esque dual stack machine ISA I am designing, I am debating with myself having instruction 0x0001 mean LIT_1 just so I can shrink the TOS register MUX from 16 input to 8 input
08:03:49 <Zarutian> nope it is going to complicate other parts such as the microcode rom

15:53:15 <dave0> hi
15:55:21 <remexre> dave0: hi
15:55:49 <dave0> hi remexre 
16:06:26 <zy]x[yz> what would you call the number which represents a fixed-point 1?
16:06:47 <zy]x[yz> e.g., if you're working with 16.16 what would you call the constant with the value 65536
16:07:09 <dave0> 1.0 i guess?
16:08:53 <zy]x[yz> is there like an industry conventional descriptive name for the fixed-point unit value, though?
16:09:11 <dave0> oh don't know :-(
16:09:47 <zy]x[yz> i guess for now i'll just call it unit until i come across something better

17:21:09 <rdrop-exit> c[_] Top of the morning Forthers
17:22:45 <rdrop-exit> zy]x[yz: scaling factor?
17:25:05 <zy]x[yz> maybe
17:25:07 <zy]x[yz> thanks
17:25:14 <rdrop-exit> np
18:42:43 <siraben> Does anyone have a good way to factor this? https://github.com/siraben/meta-yacc/blob/b032511142cd883b22f339074012c47b48ac37be/meta.fs#L40-L48
18:42:46 <siraben> It works, but I feel like there's no need to juggle the stack that much to check if a character is whitespace
18:42:59 --- quit: dddddd (Remote host closed the connection)
18:58:19 <rdrop-exit> bl over =  over tab = or  swap lf = or
18:59:47 <rdrop-exit> There are other whitespace characters than these though
19:02:41 <rdrop-exit> Other alternatives would be early exits on after each test
19:02:55 <siraben> What other whitespace characterss?
19:03:05 <siraben> I'm just thinking about ASCII ones
19:03:24 <rdrop-exit> form-feed vertical-tab
19:03:51 <rdrop-exit> carriage return
19:04:14 <siraben> bl is not a carriage return?
19:04:48 <rdrop-exit> bl is space, i.e. ASCII 32
19:05:04 <siraben> oops brain fart
19:05:17 <siraben> lf isn't defined in gforth it seems
19:05:48 <rdrop-exit> it's probably your \n
19:06:17 <rdrop-exit> they use the C language escape code I guess
19:06:40 <siraben> I see.
19:06:40 <rdrop-exit> In C \f is form feed
19:06:50 <rdrop-exit> \r is carriage return
19:07:45 <rdrop-exit> IIRC \n depends on the OS
19:08:35 <rdrop-exit> or maybe it's just linefeed
19:08:49 <rdrop-exit> \v is vertical tab
19:08:52 <rdrop-exit> just a sec...
19:08:59 <rdrop-exit> https://en.wikipedia.org/wiki/Escape_sequences_in_C
19:09:25 <PoppaVic> or, you could just do 'man ascii'
19:10:21 <rdrop-exit> If you're using anything other than 7-bit ASCII there might be other whitespace characters to contend with
19:11:20 <rdrop-exit> e.g. Unicode
19:11:29 <rdrop-exit> https://en.wikipedia.org/wiki/Whitespace_character
19:13:42 <rdrop-exit> It all depends on what definition of whitespace is actually relevant to your need
19:15:22 <rdrop-exit> Do you really need a "Mongolian Vowel Separator" :-)))
19:16:29 <siraben> PoppaVic:  Didn't know about "man ascii"!
19:16:56 <siraben> There's also man unicode it seems
19:23:38 <rdrop-exit> Unicode is messy

19:26:00 <siraben> How else to deal with hundreds of different human scripts
19:26:35 <rdrop-exit> C classifies $ 09..0d and $ 20 as whitespace characters
19:27:39 <PoppaVic> and $7f, I am sure
19:27:51 <rdrop-exit> No, that's delete
19:28:20 <PoppaVic> C isn't going to care - it's gotta' be same group as \r\n\b
19:28:22 <rdrop-exit> ht lf vt ff cr sp
19:28:45 <PoppaVic> (I speak of the input stream here)
19:29:13 <rdrop-exit> I'm speaking of C's isspace() function
19:29:21 <PoppaVic> ah
19:30:47 <rdrop-exit> or in C speak: \t \n \v \f \r and ' '
19:42:29 <rdrop-exit>  dup $ 09 $ 0d between  swap bl = or
19:45:21 <rdrop-exit> or if hex is not to your liking:
19:45:39 <rdrop-exit> dup 9 13 between  swap bl = or
19:46:37 <rdrop-exit> Assuming ASCII or a superset
19:53:21 <rdrop-exit> siraben: Regarding the hundreds of human scripts. I satisfy myself with ASCII for programming systems/languages, anything beyond ASCII is application level.
19:55:53 <siraben> rdrop-exit:  of course.
19:56:41 <rdrop-exit> The only exceptions for me were EBCDIC on mainframes and APL
19:57:45 <rdrop-exit> Oh and Commodore's PETSCII :)

20:08:00 <dave0> but if you use unicode, you can call divide   ÷   !
20:08:48 <dave0> lets see C do that :-p
20:13:12 <rdrop-exit> True, Unicode gives some really nice naming opportunities, especially for math related words, reminiscent of APL.
20:13:35 <rdrop-exit> But typing those in would be problematic.
20:14:24 <PoppaVic> Only a tablet-lover would enjoy it
20:14:55 <rdrop-exit> You could have a system that has two names for each definition, an plain ASCII one, and a "display name".
20:14:59 <PoppaVic> 'course, now yer scrolling yer damned KBD app more than the damned document
20:18:25 <rdrop-exit> You could type in something like "subset" and it would convert the display to the subset character
20:20:22 <rdrop-exit> But I'm too attached to plain old ASCII
20:21:40 <rdrop-exit> and small keyboards
