LSP-rust-analyzer broken on NixOs

[makemake-kbo]

LSP-rust-analyzer is appears to be broken on NixOS.

I set up my rust environment in a nix-shell, with all the necessary tools including rust-analyzer. However, when launching sublime, I am met with this error:

I'm attributing this to LSP-rust-analyzer downloading its own binary instead of using the one in PATH. Is there any way for this behavior to be changed?

[predragnikolic]

When you installed LSP-rust-analyzer, were there some installation errors in the Sublime Text console(ctrl+`) ? Can you remove and install LSP-rust-analyzer again and can check the console for errors?

I'm attributing this to LSP-rust-analyzer downloading its own binary instead of using the one in PATH. Is there any way for this behavior to be changed?

In LSP-rust-analyzer.sublime-settings, you can override the start command:

{
    "command": [
        "${storage_path}/LSP-rust-analyzer/rust-analyzer"  // change the path to your local rust-analyzer
    ],
}

But I would not recommend overriding the command because there is no guarantee that this LSP-rust-analyzer version is compatible with rust-analyzer you have locally, so you may run into a different issues somet

lsp-rust-analyzer does seem to start properly when uninstalling and installing with package control, but none of the LSP specific features work.

when starting sublime with the plugin installed i get this output in the console:

The first error is from EasyClangComplete. Maybe try removing/disabling it (LSP-clang should work better anyway) and then checking if that solves the problem.

[makemake-kbo]

heres the logs when starting sublime with it disabled:

Can you verify that this binary file exist /home/makemake/.cache/sublime-text/Package Storage/LSP-rust-analyzer/rust-analyzer ?

The file must exist if LSP-rust-analyzer installs successfully.

[makemake-kbo]

@predragnikolic looks like it is

[rchl]

maybe related to permissions (the makemake user is not the one used when starting from ST)?

[predragnikolic]

Maybe found the cause:

https://nixos.wiki/wiki/Packaging/Binaries

Downloading and attempting to run a binary on NixOS will almost never work. This is due to hard-coded paths in the executable.

[predragnikolic]

Other editors faced the same issue in NixOS

https://discourse.nixos.org/t/nix-shell-and-rust-and-rust-analyzer/13940/2

I do not understand or know NixOS to suggest a solution to you.

[makemake-kbo]

Thank you all for the useful info! If i find a solution ill come back and post it.

[jtojnar]

On NixOS, you are generally expected to set up development environment through nix-shell (possibly autoloaded through https://github.com/misuzu/direnv-subl). Then you should be able to use:

{
    "command": ["rust-analyzer"],
}

---

Note: Currently, direnv-subl will not be visible to Sublime LSP 2.0 because the former still uses Python 3.3. You can clone the package and modify it as follows https://github.com/misuzu/direnv-subl/pull/3
