11:39:06 <Amanita_Virosa> 'ello
11:56:42 <alexand3r> hey
11:58:38 <Amanita_Virosa> how goes?
12:00:14 <alexand3r> Amanita_Virosa: good, in a coffee shop, watching the game.
12:00:21 <Amanita_Virosa> which game?
12:00:57 <alexand3r> the world cup
12:01:14 <Amanita_Virosa> ah, cool
12:01:23 <alexand3r> what're you doing?
12:03:15 <Amanita_Virosa> playing some flash games, pondering some more FORTH stuff
12:04:42 <alexand3r> cool
12:04:45 <alexand3r> what kind of forth are you hacking?
12:05:07 <Amanita_Virosa> yet another in the long line of ones i wrote myself.
12:05:14 <alexand3r> cool
12:05:16 <Amanita_Virosa> this one is x86 realmode
12:05:27 <alexand3r> I'm using MPEforth cross-compiled onto ARM lately.
12:05:28 <Amanita_Virosa> segmented architecture
12:05:31 <Amanita_Virosa> cool
12:27:30 <ams> Amanita_Virosa: do you have them avail. for download somewhere? always interesting to look at other peoples forths
12:28:03 <Amanita_Virosa> one of my older ones is, but not in source form.
12:28:11 <Amanita_Virosa> i do expect to release this one though
12:28:14 <Amanita_Virosa> in source form
12:28:15 <Amanita_Virosa> eventually
12:28:19 <Amanita_Virosa> when i polish it a bit more
12:29:10 <ams> Amanita_Virosa: who will win the cup?
12:29:21 <Amanita_Virosa> i haven't the foggiest?
12:29:28 <ams> fair enough
12:30:27 <alexand3r> ams: I'm hoping for the dutch.
12:30:42 <ams> ditto
12:34:22 <ams> kinda crappyt game though from both spain and the nederlands
12:44:01 <ams> jeez

12:58:10 <Amanita_Virosa> you know, i don't see why more FORTHs don't use a frame pointer in the return stack
13:03:18 <ASau> For religious reasons?
13:03:25 <Amanita_Virosa> good answer.
13:06:15 <Amanita_Virosa> still, it means being able to use the return stack without needing to clean it up afterward... and it means being able to add frame-relative addressing
13:06:30 <Amanita_Virosa> i've never really been one of those who believes in named locals in FORTH... that always felt wrong to me
13:07:09 <Amanita_Virosa> but simple frame-relative locals are so useful.
13:08:19 <ASau> I hit the need to use local buffers quite frequently.
13:08:38 <Amanita_Virosa> local buffers?
13:08:41 <ASau> Maybe I should just introduce another stack to allocate local frames.
13:09:17 <Amanita_Virosa> well the thing about the simple idea of using a stack frame on the R-stack is that it uses instructions that have been well optimized on most CPUs for C
13:09:18 <Amanita_Virosa> and it works
13:10:13 <Amanita_Virosa> i have it set up so that i can use R@ like normal to index from the top of the R-stack... but i also have L@ which indexes up from the word's frame pointer
13:10:31 <Amanita_Virosa> so i can create a "local" simply by using >R and i can access it with 0 L@
13:10:52 <Amanita_Virosa> actually, i did : L0 0 L@ ; : L1 1 L@ ;
13:10:54 <Amanita_Virosa> so i can just use L0
13:10:58 <Amanita_Virosa> or L1
13:11:31 <Amanita_Virosa> and using a frame pointer means i don't have to clean up my R-stack 
13:11:57 <Amanita_Virosa> in fact, i don't even have an UNLOOP word, because EXIT automatically cleans up the R-stack.
13:13:58 <ASau> I use r! and r+!
13:14:24 <Amanita_Virosa> to overwrite things on the R-stack?
13:14:35 <ASau> Yes.
13:14:42 <Amanita_Virosa> i don't have an R! actually, but i do have an L!
13:14:47 <Amanita_Virosa> same idea, except it indexes the other way
13:15:05 <ASau> But that's because I use loops with one counter on r-stack.
13:15:49 <Amanita_Virosa> one of the nice things about using the stack frame is that you don't need to know how many cells DO pushes to be able to use locals created before the DO.
13:16:18 <ASau> I like the idea, but I'd do it differently.
13:16:19 <Amanita_Virosa> L0 stays L0 inside the DO.
13:16:31 <Amanita_Virosa> oh?
13:16:43 <ASau> I'll think about it tomorrow.
13:16:49 <Amanita_Virosa> as far as i'm concerned, this is a rough prototype moreso than a final solution
13:16:58 <Amanita_Virosa> so if you have suggestions, i'm certainly interested.
13:16:58 <ASau> It's late here, and I want to get up early.
13:17:03 <Amanita_Virosa> fair enough
13:17:25 <ASau> Good night! See you tomorrow.
13:17:28 <Amanita_Virosa> night.

22:40:54 <alexand3r> yah,. it's pretyt dead.
22:40:57 <Amanita_Virosa> how goes?
22:41:12 <alexand3r> good, just getting ready to head to bed.
22:41:25 <Amanita_Virosa> cool.
22:41:27 <alexand3r> had a pretty productive night of starcraft 2, and working on some hardware development.
22:41:31 <alexand3r> what're you up to?
22:41:36 <Amanita_Virosa> writing STRCMP.
22:41:45 <Amanita_Virosa> working on my FAT filesystem handlers
22:42:06 <Amanita_Virosa> really enjoying this project, been a while since i've been able to just code something frivolous
