[Plugin] snacks-coc.nvim: A telescope-coc alternative for snacks.picker

[xinghe98]

The Pain Point

For those of us who still rely heavily on coc.nvim for our LSP setup, the native CocList UI feels quite dated. For a long time, the go-to solution was telescope-coc.nvim. However, as projects grow larger, pulling workspace symbols or extensive references via telescope-coc often causes severe UI blocking and freezing, primarily because old bridge plugins typically trap the main thread with synchronous vim.wait calls.

The Solution: snacks-coc.nvim

I couldn't stand the micro-stutters anymore when jumping between files, so I built snacks-coc.nvim.

By directly hooking into CocActionAsync and mapping it to the beautiful snacks.picker async workers, all the blocking issues are completely eliminated. The data fetching is done silently in the background, and the UI remains buttery smooth with near-zero latency.

What's included out of the box? 🚀

I've covered over 15 high-frequency coc sources with native-feeling snacks formats (like lsp_symbol, diagnostic, and file with Treesitter previews):

• coc_definitions / coc_references / coc_implementations etc.
• coc_symbols (Document symbols)
• coc_workspace_symbols (Live full-project symbol search)
• coc_diagnostics / coc_workspace_diagnostics
• coc_commands, coc_mru, coc_links, and more.

A quick snippet for lazy.nvim users

{
  "xinghe98/snacks-coc.nvim",
  dependencies = { 
    "folke/snacks.nvim", 
    "neoclide/coc.nvim" 
  },
  event = "VeryLazy",
  config = function(_, opts)
    require("snacks-coc").setup(opts)
  end,
  keys = {
    { "gd", function() Snacks.picker.pick("coc_definitions") end,      desc = "Coc Definitions" },
    { "gr", function() Snacks.picker.pick("coc_references") end,       desc = "Coc References" },
    { "<leader>ss", function() Snacks.picker.pick("coc_symbols") end,       desc = "Coc Document Symbols" },
    { "<leader>sS", function() Snacks.picker.pick("coc_workspace_symbols") end, desc = "Coc Workspace Symbols" },
  },
}

If anyone here shares the exact same OCD for a visually pleasing and lag-free code reading experience on a legacy coc setup, I hope this plugin cures it. Feedback and PRs are highly welcome!
