08:48:50 <tangentstorm> ^ attempt to analyze and syntax-highlight the kernel.rx file from retro
08:49:56 <tangentstorm> code is here: https://github.com/sabren/b4/blob/master/go/untangle.py ( gross, i know )
08:50:20 <tangentstorm> also: https://github.com/sabren/b4/blob/master/go/tangentforth.py
08:51:15 <tangentstorm> ^ experimental vm for python. similar to ngaro, but with a different IO model and different opcodes for jumps
08:51:39 <tangentstorm> er. experimental vm for retro, -in- python.

09:52:16 <crc> Looks interesting

11:16:39 <Mat2> tach !
11:17:32 <tangentstorm> hey Mat2 
11:17:42 <Mat2> hi tangentstorm !
11:18:02 <tangentstorm> i've been up all night. just getting ready to go take a shower and go to bed
11:18:34 <Mat2> programming or coding ?
11:19:30 <tangentstorm> http://forthworks.com/dev/rancid/log/13.01.29
11:19:55 <Mat2> I have had take a look at your phyton vm
11:19:58 <tangentstorm> i'll be back in a while
11:20:02 <tangentstorm> oh? :)
11:20:14 <tangentstorm> i haven't even tried to run it
11:20:35 <tangentstorm> i was just organizing my ideas
11:21:15 <tangentstorm> i really want to try the utf-8 encoded image idea for this thing, and i'm considering moving the dictionary into a separate area of ram
11:21:23 <tangentstorm> what did you think?
11:21:30 <Mat2> nice, but conditionals on the stack are not a good idea because this means more stack shuffling needed
11:22:26 <tangentstorm> but that's actually how it works in retro
11:22:55 <tangentstorm> the primitives are all hidden away after the kernel is done, and never seen again :)
11:23:18 <Mat2> yes, but this is a weakness from forth
11:24:10 <Mat2> it really makes no sense because at cpu level continional branches depending on a flag register anyway
11:24:21 <Mat2> so why not just use it ?
11:24:52 <Mat2> this only complicate branching on cost of performance
11:25:46 <Mat2> the best way I figured out is to implement complete branch instructions, which test an immediate value and jump to an address in one instruction
11:26:03 <Mat2> (a combined compare and branch)
11:28:49 <Mat2> in forth flag conditions on the flag where introduced, because this way multible comparisons can be tested though locical combination of the conditional value
11:29:36 <tangentstorm> i see your point. i'm not really aiming for speed with this one though
11:29:58 <tangentstorm> i still plan to target your vm if i want native code
11:30:23 <tangentstorm> and i don't even know if i'll keep this thing... i was just sort of experimenting
11:31:13 <tangentstorm> the yield statement in python lets you use coroutines
11:31:17 <Mat2> I'm near finished (the vm is), at current coding the listener for metro and after this you should use the vm retro like
11:31:30 <tangentstorm> nice
11:32:16 <tangentstorm> did you ever upload the new display unit?
11:32:51 <Mat2> not yet but I will prepare a web site soon
11:33:33 <Mat2> where you can download the sources
11:34:09 <Mat2> because these git thing drives me crazy
11:34:23 <tangentstorm> i'm looking at extending the crt unit from free pascal to 256 colors and unicode... for working in the shell
11:34:30 <tangentstorm> :)
11:34:45 <tangentstorm> yeah, i could tell.
11:35:04 <tangentstorm> ok... i'd better go or i'm going to fall asleep at the keyboard. talk to you later.
