21:51 <technomancy> I have a program writtenin

21:51 <technomancy> oops

21:51 <bremner> OOPs ?

21:51 <technomancy> written in microscheme where i'm trying to write tests for it in racket

21:51 <technomancy> so i'm targeting a weird subset of where the two languages overlap

21:52 <technomancy> problem is my program uses mutable cons cells

21:52 <bremner> can you use #lang R5RS or something?

21:52 <technomancy> can i still have my tests in racket and call set-car! and set-cdr! ?

21:52 <technomancy> hm

21:52 <technomancy> yes, probably

21:53 <technomancy> i would have to stop using for/first and (probably) filter in the test harness itself

21:53 <technomancy> but that seems better than the alternative

21:54 <technomancy> hmmm actually

21:54 <technomancy> maybe it would be better to swap my cons cell for a vector instead

21:55 <technomancy> then i can keep using fancy racket stuff in the tests

21:58 littlebobeep has joined #racket

22:05 gproto23 has quit [Remote host closed the connection]

22:23 <technomancy> so glad i have this tested in racket and not just trying to test it on hardware

22:23 <technomancy> this wolud have been miserable debugging on the device

23:00 <bremner> I guess it's like an extremely high level simulator

23:00 tarod16 has joined #racket

23:00 <bremner> technomancy: it could be an interesting project to have a more complete version of microscheme embedded in racket

23:01 <bremner> (or it might make no sense; I don't know anything about microscheme)

23:02 <technomancy> yeah #lang microscheme-simulator would be cool

23:03 <technomancy> microscheme is missing a *lot*

23:03 <technomancy> because everything is C

23:03 <bremner> does it have GC?

23:03 <technomancy> no

23:03 <technomancy> doesn't even have cond

23:03 <technomancy> i added `when' but i didn't even get it right

23:04 <technomancy> https://github.com/ryansuchocki/microscheme/pull/35

23:05 <technomancy> -> https://github.com/ryansuchocki/microscheme/pull/42

23:05 <technomancy> the gc is just "run the

23:05 <technomancy> *run the main loop and set the heap counter back afterwards and make sure you preallocate everything

23:07 <technomancy> https://git.sr.ht/~technomancy/menelaus/tree/main/item/test.rkt my goofy simulator

23:08 <bremner> so why racket instead of fennel?

23:09 badkins has quit [Ping timeout: 250 seconds]

23:10 tarod16 has quit [Read error: Connection reset by peer]

23:10 <technomancy> i started this codebase before fennel existed

23:10 <bremner> make sense.

23:10 <technomancy> but also because fennel isn't schemey at all

23:11 <technomancy> racket took minimal bridging to get my code running in it

23:13 <technomancy> oh yeah also i made a gui configurator using racket https://git.sr.ht/~technomancy/menelaus/tree/main/item/gui.rkt

23:15 <bremner> right. that won't be very portable, even to other scheme variants

23:15 <technomancy> yeah don't mind much

23:16 <technomancy> only reason i care about portability is to avoid the miserable edit-upload-debug cycle and get access to a repl

23:16 badkins has joined #racket

23:17 <technomancy> portability is interesting across devices. across implementations is only interesting insofar as it accomplishes that.
