  • Disable Racer and eldoc?
    1 project | /r/DoomEmacs | 5 Feb 2022
    I recently have decided to switch to it full time, and I've encountered some annoyances while developing in Rust in it. The default rust setup uses eldoc combined with racer, which has been deprecated for a while now, for auto completion and stuff like that.

    On the server side, things are better, but RLS is still using racer for completions, which was never quite precise for me, and has a big disclaimer of "use rust-analyzer instead" in the README.

    So -- this guy used an extension (named Rust) with rust-analyzer, which was known to not work, and it didn't work(!), and the Rust extension author recommends he tries the extension made for rust-analyzer. That extension doesn't have the features he likes (it works for me and has loads of features, so I have no idea what this is about?), and so they close the issue?

    Hardly a case for the ages. Guy uses unsupported config and things don't work?

    Don't doubt it. I'm just saying -- I haven't had any problems with the rust-analyzer extension since it became the Rust default. But, yes, I had a few hiccups and crashes beforehand, no doubt. I just have to imagine it's both younger, and doing more/different things than clangd.

    I know. It's been argued for a long time. But at least if you follow the advice to install RA, it's fine. And if you don't, you won't be able to install RLS anyway, but instead get a helpful message pointing to RA.

    But the last commit to the Code extension was almost one year ago (an URL update), a pull request for a pretty annoying issue was not merged in more than a year, and the only activity on the issue tracker is people complaining about old issues and sometimes me asking them nicely to try rust-analyzer instead (but only when I'm pretty certain that their issue does not happen in RA).

    It's been asked before: https://github.com/rust-lang/vscode-rust/issues/927. Basically, rust-analyzer is not (yet?) a rust-lang.org project and it's not even going to be mentioned in the official docs until that happens.

    Yeah, see e.g. https://github.com/rust-lang/vscode-rust/issues/880.

    RA will be merged with the vscode-rust extension and aims to replace RLS (tracking issue on the vscode-rust repo).
