What is hex-cmp?

hex-cmp brings hex.pm package completion to Neovim via blink.cmp, targeting Elixir mix.exs files. It auto-suggests package names, fuzzy ~> versions, exact releases (marking retired ones), and Mix dependency options right inside deps tuples. Written in Lua, it uses tree-sitter for context and curl for hex.pm queries, with disk caching for reliability.

Why is it gaining traction?

Unlike generic cmp sources, hex-cmp detects cursor position in deps for precise completions—search hex.pm as you type app names, grab versions post-comma, or list opts like git: or only:. Signature help documents the full {app, requirement, opts} tuple, and hover (via K) shows descriptions, downloads, licenses from hex.pm github links. Cached results keep cmp hex code flowing offline.

Who should use this?

Elixir devs on Neovim 0.10+ with blink.cmp, editing mix.exs deps daily. Phoenix maintainers adding hex cmp online-style search without leaving the editor, or teams standardizing version picks to avoid retired packages. Skip if you're on nvim-cmp or avoid tree-sitter-elixir.

Verdict

Solid early pick for blink.cmp users—install as a dependency, run :checkhealth hex_cmp, and get instant value despite 10 stars and 1.0% credibility score. Docs are clear, features mature for its size; watch for broader cmp b hex code support as it grows.
