Description

Hi @echasnovski !

I recently switched from hrsh7th/nvim-cmp to mini.completion. Everything seems to work great out of the box except for one thing. When completing functions with LSP (I use golang, but I think it is true for all LSPs) the completed function appears with some garbage where parameters should be.

Example: I complete Logger.Info function which takes some parameters.
The completed line looks like this

Logger.Info(${1:})

This ${1:} is the garbage. I didn't find a way to disable it. Please help.

Neovim version

v0.11.0-dev-957+g0e42c81c7f

Steps to reproduce

1. Setup any LSP (gopls in my case)
2. Open any codebase
3. Start typing a funcion name, complete a function name.
4. Observe garbage where function parameters should be!

Expected behavior

Function's parameter list should be empty

Actual behavior

Garbage ${1:} appears

@ngortheone these are for snippet placeholders from the lsp which mini.completion does not support yet.

See here for same issue on TypeScript and Lua and how to fixed it (assume similar setting for Go LSP but I have no Go experience):

• Lsp snippets complete #193 (comment)
• Lsp snippets complete #193 (comment)

The key is to try and find something in the Go LSP config/settings similar to this: Lua.completion.callSnippet = 'Replace'

See here for conversation on future mini.snippets being a module (WIP but nothing available yet): #886 (comment)

Thanks for the issue!

Indeed, as @GitMurf said, this comes from LSP server advertising completion item as not 'Snippet' kind but instead completing as if it was a snippet.

I was also told somewhere (can not find this, unfortunately), that this can be controlled via textDocument.completion.completionItem.snippetSupport server capability. I.e. setting this to false in your LSP setup (at least until there is snippet support in 'mini.completion') should fix the issue.
