Typing `<` inserts gibberish #12379

Open SludgePhD opened 2 years ago

SludgePhD commented 2 years ago

rust-analyzer version: 84be2eaf9 2022-05-23 stable

rustc version: rustc 1.60.0 (7737e0b5c 2022-04-04)

relevant settings: Didn't find any

Sometimes, typing < to specify generics inserts $0, like here:

let v: Vec

The result is let v: Vec<$0>, which is invalid code.

This started happening on the latest release.

I am getting this also, rustc version 1.59, I tried the pre-release and release versions of RA from vscode, no change.

The $0 seems to be placeholder argument text

This is fallout from #11830.

https://github.com/rust-lang/rust-analyzer/pull/12382 will disable this feature by default until we fix it properly (that is we either have to implement or put this behind a new lsp extension, we should probably prefer the latter)
