rls-name now simply as rls in nightly

[oblitum]

On my Rust installation now RLS is now simply named "rls", instead of "rls-preview". This cause coc-rls to fail a regex match because it defaults to match "rls-preview".

It can be fixed setting rust-client.rls-name, but still, I'm leaving issue open because I'm not sure what should be the default, maybe both?

Checkout rust-lang/rls#641

@chemzqm not sure what's there to help. I have RLS, it's just named rls locally, not rls-preview anymore.

[chemzqm]

You can disable rust-client and use rls command to start server.

Hi @chemzqm, it starts fine, I just need to set rust-client.rls-name to rls and all works. Another user that reported to have to set it here: neoclide/coc.nvim#235.

I'm not sure whether the RLS devs flipped and changed names from rls-preview to just rls lately. Hence I've left the issue open as suggestion on that.

Checkout rls's documentation: https://github.com/rust-lang/rls#note-nightly-only

But it is included, I'm using it, that's not the issue.... Anyway, closing.

This is the recent discussion where renaming of RLS component from "rls-preview" to "rls" is mentioned:

• https://internals.rust-lang.org/t/announcing-rust-2018-beta-release/8901

[oblitum]

It can already be installed with just rls:

rustup component add rls rust-analysis rust-src

The above works, which means "rls-preview" is being phased out. rustup component add rls-preview rust-analysis rust-src still works, but when installed the component will be named simply "rls".

[chemzqm]

It's fixed, just like rls-vscode did rust-lang/vscode-rust@037807f

@chemzqm OK. Looks like I needed to remove <project-dir>/target/rls/ (or just the whole <project-dir>/target/) from project directory for coc stop offering installation of RLS when it was already installed in the system. The <project-dir>/target/rls had cached reference to the previous rls-preview component, and that made coc look up for rls-preview instead of rls. After deleting that folder, coc was able to pick rls by default now. So there's this problem with those project caches.
