Add support for rust-script's in source file dependencies #111

Open Andrew15-5 opened 6 months ago

Andrew15-5 commented 6 months ago

Hello. I recently found out about https://rust-script.org/, which sounds like a great substitution for shell/python scripts that I have a ton of. I made my first Rust script a few days ago and it is awesome. The problem is that rust-analyzer only works with cargo projects and doesn't help when a single-file project is opened. But another issue is that to make the script "portable" you have to include dependencies in the Rust file:

And I was wondering if it will be possible to make this plugin work with this embedded version of Cargo.toml's dependencies. I have to modify dependencies in the Cargo.toml first and then copy/sync them with the rust-script's place for those dependencies. If this plugin can work right in the Rust file, then I would only have to open a single file, which makes the workflow much simpler and quicker. (Though for rust-analyzer to work, I would still have to modify Cargo.toml...oh well...)

Afaik rust-analyzer already has support for standalone files: https://github.com/rust-lang/rust-analyzer/pull/8955.

As for crates.nvim it should be possible, but will be a decent amount of work. I'm currently debating whether to rewrite this whole plugin in rust or using https://github.com/saecki/crates-nvim-rs just as the toml parser. Until then it's unlikely though not impossible that I will implement this feature.

Ok, but apparently it doesn't just work out of the box. But I made a snippet that pretty much does just that: https://github.com/mrcjkb/rustaceanvim/discussions/253#discussioncomment-8723465.

But it only works with the standard Rust and is still useless for when using the third-party libraries. Although, if there is no Cargo.toml to check the dependencies from, how would it know which libraries to load. Would be cool if rust-analyzer can read the rust-scripts's in source file dependencies. Then all the problems would be solved.

Until then it's unlikely though not impossible that I will implement this feature.

Sure. No rush.
