Description

with rust:

Screencast.From.2024-11-07.09-33-42.mp4

with python for example(or other):

Screencast.From.2024-11-07.09-36-37.mp4

Steps to reproduce

1. copy init.lua that I provided
2. run

nvim -u init.lua main.rs

3. wait while rust-analyzed loads(~5 secs)
4. type

fn main() {
    pri // or smth other
}

5. select not first completion

Expected behavior

work as first completion(only brackets, cursor inside, no ...)

Actual behavior

... inside brackets second brackets after and cursor in them

Additional context

In my config specified rustaceanvim version = "^4" from start.
This issue happens only few month, not from start 100%.
Issue occurs even on version "^3".
So I think issue in your plugin, not rustaceanvim.

I had encountered the same issue. After lots of trails and errors I've nailed down to snippetSupport LSP capability. Setting

vim.g.rustaceanvim = {
    server = {
        capabilities = {
            textDocument = {
                completion = {
                    completionItem = {
                        snippetSupport = false
                    }
                }
            }
        }
    }
}

solves the issue for me.

Digging the rabbit hole leads me to https://github.com/rust-lang/rust/blob/78bb5ee79e0261e8e47476b631da02acc1cb03ef/src/tools/rust-analyzer/crates/ide-completion/src/render/function.rs#L278 where the … seems to came from. I'm not familiar with LSP enough to determine whether it's rust-analyzer's problem, cmp-nvim-lsp's problem or it's purely a config error though.

Thank you, it works, but now snippets, that may be interpreted like lsp completion

For example something.ok<CR> -> Ok(something)

[hafeoz]

OK after some git bisection I've found hrsh7th/cmp-nvim-lsp@44b16d1 to be the culprit. Overriding these properties one by one reveals textEdit to be the offending one.

A quick search then reveals hrsh7th/cmp-nvim-lsp#72 (which has a confusing and unrelated name for those unfamiliar with LSP internals like me...), and using codes from hrsh7th/cmp-nvim-lsp/72#issuecomment-2425963432 solves the issue while allowing snippet completion.

We probably should close this issue as dupe and track the progress on hrsh7th/cmp-nvim-lsp#72?
