cmp2lsp

Convert nvim-cmp sources to native LSP sources, allowing you to use your favorite nvim-cmp sources with any completion engine. Native, mini-completion, care, coq, blink, whatever.

Why?

I want to try out different completion engines without losing my beloved cmp sources.

I also see a bunch of new completion plugins writing the same code to hijack cmp sources, and figured I could save them some time and let mini-completion users in on the fun.

Usage

It's important that this plugin loads before all of your cmp sources are registered, but that setup is called after the sources are registered. This is a bit tricky. I've been using this:

{
  "benlubas/cmp2lsp",
  config = vim.schedule_wrap(function()
    require('cmp2lsp').setup({})
  end)
}

If you want to configure it, just look at ./lua/cmp2lsp/config.lua, there's not much there right now.

Unsupported

There are parts of the cmp source 'spec' that are currently unsupported:

• get_position_encoding_kind - completely ignored
• resolve - I'm planning to implement this soon
• execute - same here

Shout out

@max397574 I basically ~stole~ repurposed the entire ./lua/cmp/init.lua file from care.nvim's cmp-care plugin which hijacks cmp sources for care.

@Saghen with blink.cmp the WIP plugin that made me want to try out a new completion engine.

@jmbuhr with quarto-nvim which does some similar stuff creating a shim language server in Lua, which I used in neorg-interim-ls, and now here as well!
