"Extract into function" puts extra "\" in generated function only in WSL

[elithrade]

Hi,

I have a strange problem I cannot figure out why.
I have the following code:

fn main() {
    let n = 100;
    for i in 0..n {
        println!("{}", i);
    }
}

I select the for loop and choose "Extract into function" the generated function looks like this:

fn main() {
    let n = 100;
    fun_name(n);
}

fn fun_name(n: i32) {
    for i in 0..n {
        println!("{\}", i);
    \}
\}

I cannot figure out where those "" come from. I am using Neovim in WSL. My rist-anaylzer version is:
❯ rust-analyzer --version
rust-analyzer 1.77.1 (7cf61eb 2024-03-27)

I have the same setup on my Windows machine and it's working as expected. Any ideas? Is this a WSL issue? Any helps appreciated.

You probably have a different version on Windows. Can you test with a binary release from GitHub?

I tried the latest binary, still getting the same problem,

My Windows version is

#16607 sounds like the same issue.

[lnicola]

Yeah, but that one's fixed.

It's actually #16867 which is an issue on Neovim's side. It's fixed in v0.10 (which looks like it'll be released in May), though the workaround described in #16867 (comment) works too:

As a temporary workaround, if you're using rustaceanvim, you can set vim.g.rustaceanvim.server.capabilities.experimental.snippetTextEdit to false (mrcjkb/rustaceanvim#303 (comment)).
If you're using something else, you should be able to tweak the flag in a similar way in Lua.
