What went wrong

Using RLS ALE will routinely report / lint only once.

Reproducing the bug

Steps for repeating the bug:

1. Open a file
2. make an error
3. see error or warning report
4. fix error
5. see error or warning stays.

I realize this issue is unhelpful as written, trying to come up with a consistent failing test to post as an example.

[tbremer]

I was able to recreate the issue, but I am not totally sure it is with ALE, so sorry if this is the case.

Given a lib with a bin inside of it such as:

.
├── Cargo.lock
├── Cargo.toml
├── src
│   ├── bin
│   │   └── main.rs
│   └── lib.rs
└── target

Making an edit that creates an error (as reported with cargo check) on lib.rs only correctly reports once using RLS as the linter.

Here is a repo where the issue can be reproduced: https://github.com/tbremer/ale_rls_error

[tbremer]

It appears if I use the _nightly_ toolchain of Rust and RLS linting works as expected, so this may be an RLS issue, but I'd like to see if we can get the stable version working correctly.

Hi @tbremer

Is this this still an issue with ALE + RLS ?

[tbremer]

Sorry, I have not come back in a while and tried to re-create the issue. I don't know.

[w0rp]

I'll close this, as this is probably out of date. Someone can open a new issue if there's a problem.
