Lux: A luxurious package manager for Lua

I've been awaiting the rocks.nvim team to migrate to this

This is interesting but I feel like a lot of these Rust-inspired package managers are a little... too inspired by Rust. This project for instance uses .toml as a config file format, presumably because that's what Cargo does.

But I think for this project in particular, Lua for the config files would have been a better choice!

I think that Lua tries to be a good configuration language (it started as a configuration language called SOL (sun), which configured reports for lithology profiles), and in fact Luarocks uses "rockspec" for their config, which is syntactically Lua. Lux claims to be inspired by Luarocks, and yet they chose to use toml over lua for config. I'm wondering why? What was wrong with lua that made toml a better choice?

edit: Okay, I've found more information where they say they support both formats... which, I don't know if that's the right call? Seems like going with one or the other is better from a project management standpoint, although I can see why they want to give users the option.

> Not everyone may want to migrate (nor use) the TOML system for describing a project. For this reason, I’d had liked Lux to support a rockspec file alongside the TOML file (similar to the old project.rockspec format). This has finally been implemented! By creating a file called extra.rockspec in the project root, you will instruct Lux to merge the TOML and the rockspec together when performing any sort of operation.

I completely dislike the practice of giving options for no reason other than to give options. Don't make me learn different ways of doing the same thing to succeed in an ecosystem. Don't make me learn differences and similarities. If one way works properly and doesn't have obvious downsides, stick with having one way. If it has obvious downsides, stick with having a different one way. Subjective format taste isn't a real downside. Pick one format and stick with it.

The line from the zen of Python about how "there should be one-- and preferably only one --obvious way to do it" is something that people all too often forget the value of.

The zen of Python should be the zen of all languages.

		Yes, it should be. Sadly it's not even unambiguously the zen of Python these days.

		Yes, one way to do it. Sync or async!

Good thing we're not giving options for no reason other than to give options ;)

Nope. We chose TOML as the default for various reasons:

- Simplicity. There are use cases for a turing complete configuration language. Lux is not one of them.

- Ergonomics. The ability to edit it using the CLI (technically, that could be possible with Lua too, but it would be a lot more complex and not a very pleasant UX).

> which, I don't know if that's the right call?

The reason we currently support importing a Lua extra.rockspec is ease of migration for complex projects, e.g. with platform-specific overrides (not yet supported by the TOML spec).

Thanks that does answer my question! Had you considered parsing a subset of lua to get the properties you want? That way users don't have to learn a whole other syntax. I'm thinking in particular of my students whom I teach lua. They struggle enough learning one language, having to teach a second with all its quirks seems like a lot to throw at them.

Do you think that is more difficult than explaining to the students why they can’t use loops in their lua config files?

	▲	ModernMech 11 minutes ago \| parent [-]
		I wouldn't present it to them as "these config files are the same thing as Lua but without loops", but instead "these are config files and they have the same syntax as the Lua records we just learned about". And I would prefer that over "these are config files and they have a slightly different syntax as the Lua records we just learned about." Although I can see merits on discussing that syntax differences exist between languages, that tends to overwhelm people learning their first language.

I don’t understand why a package manager needs lint support.

"beautiful", "elegant", and "tasteful" have all been used to puff up various libraries, frameworks, etc, and now we have "luxurious" to add to the long list of ridiculous adjectives used to puff up tech. Lovely.

I have always thought that those qualities should be shown, not said. Both in software and in life.

Honestly it makes me roll my eyes, "let's describe our software utility as if we're trapped in a perfume commercial". But on the other hand, I think when creating something it does help to have underlying vision, even if it's abstract or doesn't quite make sense.

		I think that is why despite it being eye roll inducing, there is still value to these descriptors as it explains what they are going for. In this case it tells us they are prioritizing the feel over everything else and for a package manager that is pretty solid focus.
