<lloda>daviid: i use https://paste.debian.net/1216735/

<civodul>dthompson: hey! can't wait for the Guix package for https://davexunit.itch.io/bonnie-bee :-)

<civodul>thumbs up, it looks pretty fun

<dthompson>civodul: hey thanks! the git repo has a guix.scm file so it's pretty easy to play for guix users. not 'guix install bonnie-bee' easy, but close enough!

<civodul>yup, neat

<dthompson>^ for anyone else seeing this: I made a game in 10 days for the lisp game jam. using guile, of course!

<civodul>i'll give it a go tonight instead of pretending to be productive ;-)

<civodul>woow, quite an achievement

<civodul>you're not a random hacker tho :-)

<dthompson>the game only takes a few minutes to beat. it's not that hard for people used to this type of game, but those unfamiliar with the shoot-em-up genre may find it difficult. if you're not having fun, just press ESC and that's that. :)

<dthompson>I'm just happy to have released a pretty decent free culture game.

<dthompson>code is gpl3, assets are cc-by-sa.

<chrislck>nice package... I presume this package will be runnable until the end of time?

<dthompson>hahaha probably not!

<dthompson>but the guix.scm makes it less prone to bitrot

<dthompson>guix.scm file*

<chrislck>here's my error report: https://pastebin.com/raw/bvCeUEUC

<civodul>dthompson: you can also add a channels.scm file to be on the safe side

<chrislck>(also tried guix environment --pure -l guix.scm)

<dthompson>looks like guile-sdl2 is failing. that is strange.

<dthompson>would need to turn up guix verbosity to understand why

<dthompson>always something wrong, despite my best efforts!

<dthompson>thanks for trying. I will help debug for as long you have the energy to keep trying.

<chrislck>np. may not be always timerich but can feed back regularly until it's fixed.

<dthompson>chrislck: I'm sure you have better things to spend time on. but if you do try again... happy to help. :)

<dsmith-work>Hey Hi Howdy, Guilers

<chrislck>np not sure how much I can offer; but if you push into your repo I'll feed back from time to time

<RhodiumToad>ugh, why do library authors invent so many ways to make memory management hard

<taw10>Guilty. Sorry.

<cwebber>hm

<lilyp>dthompson, chrislck: with recent guix, you should be able to simply (define chickadee (@ (gnu packages game-development) chickadee)) and ignore the local definitions

<manumanumanu>Ahoy hoy!

<manumanumanu>I haven't touched a proper computer for almost three weeks

<manumanumanu>I have almost forgotten how to touch type

<manumanumanu>and I had to think twice before a cdar.

<manumanumanu>anything fun going down?

<RhodiumToad>I found what I think is a bug in the module system :-)

<manumanumanu>exciting!

<manumanumanu>Code?

<RhodiumToad>the demonstration is here: https://gist.github.com/RhodiumToad/d92417aa4df36771ce993196c940a08f

<RhodiumToad>haven't written it up for a proper bug report yet

<RhodiumToad>the cause is that define-module* processes #:re-export _before_ processing #:duplicates, which seems both wrong an (as shown) inconsistent

<manumanumanu>ooh

<manumanumanu>that is a very nice find

<RhodiumToad>the fact that it behaves differently according to whether the sources were recompiled is a nice touch

<manumanumanu>which I don't really understand the mechanics of...

<RhodiumToad>even I haven't figured out exactly why that happens

<RhodiumToad>I'm guessing it's an expand vs. load thing (in the sense of (eval-when))

<lilyp>welp, I cheated really hard to get a backtrace :(

<civodul>dthompson: https://git.dthompson.us/guile-sdl2.git returns the wrong content-type it seems, which breaks guix.scm

<dthompson>lilyp: I need to build against git checkouts since I fixed bugs in the dependencies during the jam.

<dthompson>civodul: huh... I don't get that error here. I ran 'guix pull' this morning and rebuilt my environment, too.

<lilyp>Uhm, you really don't need to build against a checkout of the release tho

<lilyp>change a bit in the hash, it'll barf

<dthompson>I don't follow

<lilyp>Guix doesn't barf if you have the thing already in store.

<lilyp>You need to change the hash to make it see "oh, there's something different".

<dthompson>I've been pushing new commits all week and updating the definitions

<dthompson>not one problem

<dthompson>this would have to be a very recent regression that guix introduced

<civodul>dthompson: perhaps because you have it in cache?

<civodul>yeah what lilyp wrote

<lilyp>It's been there for ages :P

<dthompson>it's possible, but I ran 'guix pull' not that long before I started the jam.

<lilyp>Try `guix gc' otherwise if you're not convinced

<dthompson>and have had no problems.

<dthompson>I've developed this for literally years

<dthompson>this way*

<dthompson>I'll try a gc and see if I can reproduce

<lilyp>Trust me, I've been bitten by this for the past two years.

<dthompson>by other git repos? or just mine?

<civodul>yeah, you can try "guix build /gnu/store/1sfyih800f5w0qzrx0hj6gvhmk5vi712-git-checkout.drv --check"

<lilyp>by my own contribution to Guix channels, including the main one

<dthompson>I will run 'guix gc' and see what happens

<dthompson>the fact that this appears to be a non-universal issue is interesting

<dthompson>I just rebuilt the environment from scratch and it all worked.

<dthompson>why can't I reproduce this issue???

<cwebber>o/

<civodul>dthompson: did you try the command above?

<civodul>probably you can't reproduce it because you already have the output of that derivation in store

<dthompson>civodul: I gc'd.

<dthompson>it cloned again. no issue.

<civodul>(cd /tmp/guile-sdl2; git checkout d31c27ac48f81a534b28531e3d5fa626890be59f; guix hash -rx .) => 106pnw4ifgkrgyj84jgpz5gnbgshjcrp10wcyw1skgzqni1mrmg3

<civodul>it's a good idea to add the usual 'file-name' field because that avoids mistakes like when you update the commit ID but forget to update the content hash

<civodul>anyway, not sure if that's what happened, weird!

<civodul>dthompson: i just played, got to hit "x" a few times and all, much fun :-)

<civodul>and music!

<dthompson>civodul: thanks! first time I've made game music. very basic but works.

<dthompson>I'll check for mistakes with the git checkouts but I just saw guix re-clone the repos. when I update the commit id I always edit the hash so that guix throws an error about it. then I copy/paste the actual hash it outputs.
