Add luacheck and GitHub workflow

[Panquesito7]

See GitHub Help for more information about GitHub actions.

You need to create and configure .luacheckrc in all repositories before adding the CI, otherwise you'll get a lot of (false) errors. If you don't know how to start, you can take inspiration from Cloud Items' .luacheckrc.

What? Who's setting up CI?

[Panquesito7]

You can set up CI with GitHub actions by adding a workflow. See my first link for more information.

[fluxionary]

But... CI for what? Sorry, I'm all for CI, I'm just not sure where/how it's relevant right now. This isn't a code repo.

[Panquesito7]

No, I'm talking about Lua repositories. If you need help, I can help setting it up. 🙂

I created the issue here because this is a issue tracker repository.

[fluxionary]

Oh, you're just suggesting that I set up some sort of basic style checking on the lua repos and forks I manage? I suppose I'm not against playing around w/ that; I've given up on doing any real sort of continuous testing on mod repos cuz I'd need to, like, mock a full instance of the game. I also run an IDE that runs a luacheck in real time while i edit the code...

[fluxionary]

I suppose I'll add this to the bls_custom repo for experimentation

[fluxionary]

@Panquesito7 any comments on what I'm doing wrong here? It's kvetching about docker, and I don't know why.

[Panquesito7]

The code has various warnings which need to be fixed. Will check what's going on and try to fix those issues by creating a PR.

[fluxionary]

Does it? The only output I see is

 Check failure on line 1 in .github

@github-actions github-actions / luacheck

.github#L1

Docker run failed with exit code 1

BlockySurvival/bls_custom#2

[Panquesito7]

Now that it is working with bls_custom, I can start working with the other mods. What do you think?

[fluxionary]

I think you should go for it. I'd prefer to deal w/ the verbana mod myself, but feel free to put in PRs against the other repos we manage, and I'll set it up on the github side.

[Panquesito7]

I've created various PRs in various repositories. @fluxionary, you probably want to watch all BlockySurvival repositories to get all notifications.

@Panquesito7 nice work :+1:

But... CI for what? Sorry, I'm all for CI, I'm just not sure where/how it's relevant right now. This isn't a code repo.

@fluxionary you can still do integration-testing for the meta-repo. We are doing that for our pandorabox-mods repository: https://github.com/pandorabox-io/pandorabox-mods/blob/master/test.sh https://github.com/pandorabox-io/pandorabox-mods/blob/master/.github/workflows/integration-test.yml

For every commit a minetest-instance is started that checks if the engine starts and does some basic assertions: https://github.com/pandorabox-io/pandorabox_custom/blob/master/integration_test.lua

Background: the master branch is automatically kept in sync with the minetest-server This helped prevent a lot of potential crashes.

The CI-Tests even run when the dependabot updates a repository and creates a PR: https://github.com/pandorabox-io/pandorabox-mods/pull/490 (this was actually @coil0's idea...)

Let me know if you need help setting that up...

[fluxionary]

Thanks Buckaroo, that's really helpful. I can probably set it up myself sometime later when I get some energy.

[fluxionary]

This is towards the top of my "high priority" list. Just need a few good days.

This is towards the top of my "high priority" list. Just need a few good days.

I tried to whip up a PR for this a few days ago but had some issues:

• [ ] IRC-Mod needs special lua libraries
• [ ] Mods aren't structured as worldmods folder
• [ ] Naming issue with the REPOS folder

Those aren't blockers but the repository can't be cloned 1:1 in a worldmods folder in the current state. I guess you are working with a world.mt file that enables every mod explicitly?

[fluxionary]

Yes, we're using the main "mods" folder and a world.mt file to enable the mods; this allows admins to easily disable/enable mods, as well as individual submods from modpacks (and we very much do the latter). If there's something i can do to the REPOS folder & the associated symlink to make it work in a worldmods folder, w/out removing the current functionality, I'd love to hear it. Keep in mind that part of the problem is that the terumet mod's root isn't a proper mod folder itself.

[fluxionary]

Also, I'm fairly certain a couple other mods require special lua libraries (e.g. verbana requires a sqlite library); if we had to configure the test server to omit these handful of mods, that'd still be a huge improvement over the current situation.

Keep in mind that part of the problem is that the terumet mod's root isn't a proper mod folder itself.

We have a special case with the moretrees mod (we only symlink a few mods in the pack): https://github.com/pandorabox-io/pandorabox-mods/tree/master/.partial_mods All names starting with a dot are ignored by the engine.

Also, I'm fairly certain a couple other mods require special lua libraries (e.g. verbana requires a sqlite library); if we had to configure the test server to omit these handful of mods, that'd still be a huge improvement over the current situation.

You could of course just remove them at the start of the test script

[fluxionary]

I'm working on refactoring things so that it'll work in either setup. Not feeling well rn though so it might be another while.

[Panquesito7]

@fluxionary there are some repositories (non-meta repos) that are still missing LuaCheck. I'll start creating more PRs when I have time.

[Panquesito7]

I'm now working on to add LuaCheck for more repositories. 🙂

[Panquesito7]

This issue is kinda old, but I still see a few repositories with no LuaCheck. I'll be making PRs for those. I hope that's fine. Thanks.

[fluxionary]

fine by me. i've actually started using pre-commit, luacheck, and stylua in all my own projects, it certainly helps catch stuff.
