Introduction
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 uses an optional custom fuzzy matcher to easily handle 20k+ items. It provides extensibility via pluggable sources (LSP, snippets, etc), component based rendering and scripting for the configuration.
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)
- Snippet support: native
vim.snippet(includingfriendly-snippets),LuaSnipandmini.snippets - External sources support (community sources and compatibility layer for
nvim-cmpsources) - Auto-bracket support based on semantic tokens
- Signature help (experimental, opt-in)
- Command line completion
- Terminal completion (Nightly only! No source for shell completions exists yet, contributions welcome!)
Compared to built-in completion
- Typo resistant fuzzy matching
- Smarter scoring
- Proximity + frecency score bonuses
- Prefetching to minimize LSP latency
- Support for external non-LSP sources (snippets, path, buffer, git, ripgrep, ...)
- Documentation popup
- Ghost text
- Signature help
- Auto-bracket support based on semantic tokens
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
- You may try magazine.nvim which includes many performance patches, some of which have been merged into nvim-cmp
- 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
- Prefetching to minimize LSP latency
