Blink Completion (blink.cmp) ​

IMPORTANT

This plugin is beta quality. Expect breaking changes and many bugs

blink.cmp is a completion plugin with support for LSPs and external sources that updates on every keystroke with minimal overhead (0.5-4ms async). It use a custom SIMD fuzzy searcher to easily handle >20k items. It provides extensibility via hooks into the trigger, sources and rendering pipeline. Plenty of work has been put into making each stage of the pipeline as intelligent as possible, such as frecency and proximity bonus on fuzzy matching, and this work is on-going.

Features ​

  • Works out of the box with no additional configuration
  • Updates on every keystroke (0.5-4ms async, single core)
  • Typo resistant fuzzy with frecency and proximity bonus
  • Extensive LSP support (tracker)
  • Native vim.snippet support (including friendly-snippets)
  • External sources support (compatibility layer for nvim-cmp sources)
  • Auto-bracket support based on semantic tokens
  • Signature help (experimental, opt-in)

Special Thanks ​

  • @hrsh7th nvim-cmp used as inspiration and cmp-path/cmp-cmdline implementations modified for path/cmdline sources
  • @garymjr nvim-snippets implementation modified for snippets source
  • @redxtech Help with design and testing
  • @aaditya-sahay Help with rust, design and testing

Compared to nvim-cmp ​

  • Avoids the complexity of nvim-cmp's configuration by providing sensible defaults
  • Updates on every keystroke with 0.5-4ms of overhead, versus nvim-cmp's default debounce of 60ms with 2-50ms hitches from processing
    • Setting nvim-cmp's debounce to 0ms leads to visible stuttering. If you'd like to stick with nvim-cmp, try yioneko's fork or the more recent magazine.nvim
  • Boosts completion item score via frecency and proximity bonus. nvim-cmp boosts score via proximity bonus and optionally by recency
  • Typo-resistant fuzzy matching unlike nvim-cmp's fzf-style fuzzy matching
  • Core sources (buffer, snippets, path, lsp) are built-in versus nvim-cmp's exclusively external sources
  • Built-in auto bracket and signature help support

Planned missing features ​

  • Significantly more testing and documentation
