[ayamir]

Pull request overview

This PR migrates the Neovim completion stack from nvim-cmp + wilder.nvim to saghen/blink.cmp, and updates related integrations (LSP capabilities, Copilot, and theme integration) to match the new completion engine.

Changes:

• Replace hrsh7th/nvim-cmp configuration with saghen/blink.cmp (including cmdline completion) and add blink.compat + blink-copilot integration.
• Update LSP capability wiring to use blink.cmp capabilities.
• Remove wilder.nvim and copilot-cmp plugin/config and adjust Catppuccin integration to blink_cmp.

• These comments still reference copilot-cmp, but this PR removes copilot-cmp in favor of blink integration. Please update the wording to reflect the current integration (e.g., blink-copilot) or make it generic to avoid future confusion.

opts_extend won’t have any effect here because this spec doesn’t define opts, and the config function ignores any opts passed by lazy.nvim. Either remove opts_extend, or switch to providing an opts = { ... } table and have the config function apply/merge that table so users can extend sources.default as intended.

Suggested change

	config = require("completion.blink"),
	opts = {
	sources = {
	default = {},
	},
	},
	config = function(_, opts)
	require("completion.blink")(opts)
	end,

this is actually valid, as folke suggested in https://lazy.folke.io/spec

add we can also remove the lua/user related code.
but i think the cleanup and refactor itself needs another pr.

I believe this PR can be reviewed now if you have time~ @charliie-dev

port some useful personal blink.cmp config, here the ref: https://github.com/charliie-dev/nvimdots.lua/blob/main/lua/modules/configs/completion/blink.lua

I was looking forward to this as well, as this could enable us with more options from blink.cmp dev ecosystem, also with a better flexibility for using other ai edit prediction service.
I would love to try refactor the code with newer choices for edit prediction, and possibily code-companion side of thing.

[ayamir]

IMO it's good enough to merge

[charliie-dev]

@Cloud0310 maybe the ai part can be merged until next pr

[charliie-dev]

LGTM

Fine with me, yesterday I was busy doing something else.
I'll try the new 0.12 branch and make progress upon.

Is 0.12 already able to be the main branch now? If so, I thought we can make it default.
