Rust run in separate file breaks

[EntilZha]

When using Script:run with a active file that is not main.rs, it returns an error that a main function cannot be found.

This boils down to script probably trying to run the current file, than running the project's main file.

With some guidance, I can provide a PR to help fix this/add the behavior since its a little annoying. Alternatively, can script options be used to achieve the same goal?

Ug. Seems like script options is the simplest approach for when you want to run a project, since script is built on the premise of running the current file.

I was hoping to do something like that, but so far haven't found the right parameters. Is there an easy way to see what Script is trying to run? I can only see the command output

[EntilZha]

Oh, I see the issue. I was assuming it was running cargo run, when it is using rustc

Maybe the solution is to make a PR to have a cargo grammar? This would be analogous to compiling a program with javac vs maven/sbt I think?

I don't know how having two grammars that apply to the same file extension would work. Is one disable-able?

[rgbkrk]

That's where I shrug. I've never worked with rust whatsoever and didn't introduce this binding into script.

Feel free to pick what you think is right, we'll merge it and move forward.

Working on changing the grammar, what is the best way to look at what script runs? I changed the grammar/followed developer instructions but seems like nothing has changed

[EntilZha]

Got that working, had to relaunch a couple times, but pointer to the right way would be helpful.

Trying to debug some issues where it compiles once fine, but has trouble removing files the time after

[EntilZha]

Upon further investigation, it seems like running the build commands works, but conflicts with linter-rust which runs cargo build. The run command effectively does cargo build && cargo run. Somewhere linter is run at the same time which creates the problem.

I am not sure how to solve this, will think about it more

Yay race conditions!
