error: Unknown binary 'rust-analyzer' in official toolchain 'stable-x86_64-unknown-linux-gnu'.\n

[Android789515]

Summary

After updating Helix to 24.3 (1796735) I no longer have syntax highlighting for Rust files.

Reproduction Steps

I tried this:

1. hx .

I expected this to happen (syntax highlighting is present for other files):

Instead, this happened (no syntax highlighting for rust files):

For syntax highlighting, you need to update the runtime folder. https://docs.helix-editor.com/install.html#configuring-helixs-runtime-files

For the LSP, you need to install the rust-analyzer component from rustup. But those logs seem to be from half a year ago from the timestamp.

[Android789515]

Must be the highlight query. I updated the grammar and built them after updating Helix.

How do I update the highlight query?

[kirawi]

You have to copy over the new runtime folder with the new highlights

[Android789515]

I don't understand what that means.

[kirawi]

Delete your old runtime and copy over the new runtime following https://docs.helix-editor.com/install.html#configuring-helixs-runtime-files

[Android789515]

Thanks.

a note for future wanderers: this is not a helix issue! from what I understand, helix simply searches for a pre-configured binary name in your $PATH to tell if the lsp server for a given language exists in your system or not. in case of rust it finds one under $HOME/.cargo/bin, which is symbolic link to the rustup binary and created by deafult when you install rust via rustup. regardless of whether you have added/installed the rust-analyzer binary.
you need to run rustup component add rust-analyzer to actually install the rust lsp (rust-analyzer) after which rustup acts as a multicall binary (imagine something like busybox) and the symbolic links starts working as well as the lsp functionalities. I wonder why rust handles this in such an abysmal way!
