@pxeger I'm getting an error when I try to run code (tried in Pip and Whython): websocket connection unexpectedly closed with code 1011

BTW, staging.ato.pxeger.com is working, for anybody else like me who just needs to try some code out

Welp, now staging has the same issue

2 hours later…

pxeger

06:54

uh-oh, this isn't good

this happened yesterday, but I just restarted it and it fixed itself

but if it keeps happening then something is clearly broken

@PyGamer0 Let me rephrase that: On average it has shorter programs than Vyxal.

@DLosc Now I really don't understand... even though a restart fixed it on ato., it isn't working on staging.ato.

ok this was unrelated

I really don't think Unrelated String would do something like this :P

@pxeger Hey, yeah I wasn't able to get it to work with GHC 9, but any GHC 8 should work

@pxeger I'm not able to see the error message because it says unknown language then brings select language menu over the button for error/etc

pxeger

@DarrenSmith yeah, sorry, because of the issues I've been having the past few days I had reverted to an older version

The error message was "cannot allocate memory" which seemed unlikely to be right

Darren Smith

Hmm, I haven't seen that error. Sounds like you got it to compile though, curious why it didn't see the packages in the directory by default, what did you have to do to fix that?

pxeger

I didn't fix it; that error message appeared anew when I started running it on ATO instead of on my local computer

I think the reason it doesn't see the packages is because I deleted them though ;)

Darren Smith

If you run it with a flag -c (which should just save a file but not generate and run a haskell program) does it work? There might be something weird about it compiling haskell source (which is how it executes nibbles programs). Similar to Husk in that regard, but Husk hasn't been done too it looks like

Ah ok, there is a fix in the memoize one which isn't in the official repo yet (it get's really slow for large integers without it)

doesn't matter much though, only affects recursive fns which are rare

pxeger

oh, hmm

Ok, I think I need to run nibbles from in the nibbles working directory for it to detect the modules?

Darren Smith

20:32

it should be able to be ran from anywhere, but I think it would need to be compiled from there

(the nibbles binary compiled from there that is)

pxeger

otherwise I still get "Could not find module Data.Function.Memoize" errors etc

nibbles -hs <<< '|_~`^+`@ 2' && ghc -v out.hs gives these logs:

gist.github.com/pxeger/5340640147fe10618af1f8ae83e9c021

Darren Smith

ah actually you are right. I didn't realize that issue

so yeah it would need to be ran from there too... I really regret compiling to HS instead of just interpreting... premature optimization :(

pxeger

so running it from the nibbles directory works fine in the medium term, but I don't know why it doesn't work on ATO...

Darren Smith

on ATO does the -c or -hs option work? I suspect it is nibbles itself trying to call GHC and start processes that causes the issue

(those options will not call any other process and just generate .nbb or .hs files)

pxeger

looks like the out of memory error was probably a genuine one: the maximum memory usage of nibbles <<< '|_~`^+`@ 2' 4 is 196MiB

(ATO limits you to 128MiB)

I should probably try a simpler example program

Darren Smith

20:41

I suspect it calling GHC uses a ton :(

pxeger

yup :/

ato.pxeger.com/…

I guess I'll raise the memory limit...

nibbles: out: callProcess: posix_spawnp: does not exist (No such file or directory)

Darren Smith

so I think in nibbles.hs you'll need to change "out" to "./out" I already did that in latest version but not in stables release yet

pxeger

ah ok, that should be simple enough to fix

Darren Smith

I wish this was easier... thanks for taking the time to work through it

pxeger

yes, hopefully that'll be the ironing out of most of the issues

Darren Smith

20:46

line 158 I think

pxeger

Would it be better to install Nibbles from main in the GitHub repository rather than a release?

Otherwise I can just do a patch

Darren Smith

The easiest would probably be golfscript.com/nibbles/nibbles-latest.tgz (it has the latest changes). That should be easier than github since it includes the libraries it depends on (those aren't in github)

pxeger

ah ok

Darren Smith

normally that link could contain some unvetted changes, but I haven't done anything wild to it since 0.25
