Saving file on Nix-Shell deletes the contents of the file

[LegitCamper]

Summary

when using helix in a nix-shell :w deletes the contents of the file 💀

I am on nixos and I was originally using a shell.nix file for rustup and cargo. After noticing this annoying behavior I deleted the shell.nix, but the issues still occured. I tested the issue in other shells and it does not occur. The only difference is the packages in the shell nix-shell -p openssl pkg-config. I am not sure what causes it, but I have lost a bit of progress on my project when I thought it was saved only to find out my work was gone.

[nix-shell:~/projects/my-spacetraders]$ hx 

[nix-shell:~/projects/my-spacetraders]$ cat spacetraders/src/tests/responses.rs

[nix-shell:~/projects/my-spacetraders]$

Reproduction Steps

https://asciinema.org/a/QppILd1lo1uwpVtK0Lrd5jzjW

I tried this:

1. hx
2. :w

I expected this to happen:
I expected the file to be saved

Instead, this happened:
everything in the file was deleted

What does the log file say when reproducing this in verbose mode? https://github.com/helix-editor/helix/wiki/FAQ#access-the-log-file

You can run hx -v --log log.txt to make a log just for that hx session.

I only get anything with hx -vvv --log log.txt

I don't see anything in here that looks bad. It looks like you aren't running rust-analyzer, right?

[LegitCamper]

yes, since I deleted the shell.nix file I don't have rust-analyer installed.

[the-mikedavis]

This is in https://github.com/LegitCamper/my-spacetraders, right? I tried reproducing with that same file but didn't see it clear out the file. Do you have any custom config in ~/.config/helix/config.toml or ~/.config/helix/languages.toml?

[the-mikedavis]

Ah yeah the line formatter = { command = "cargo", args = ["clippy"]} is problematic: that's piping files through cargo clippy on save, so the stdout output of cargo clippy replaces the document.

[LegitCamper]

damm. I think you are definitely right it used to be:

[language.config]
checkOnSave = { command = "clippy" }

I changed it to work on nix. Can I run Clippy in a similar fashion to rust-analyzer?

[gabydd]

From this https://rust-analyzer.github.io/manual.html#clippy it seems like you should just be able to set it to clippy for it to work, I don't think it is actually specificing a binary on path to run
