Blink Pairs (blink.pairs)

Intelligent auto-pairs with rainbow highlighting for Neovim

blink.pairs combines auto-pairs with rainbow highlighting, via a custom internal parser. The parser takes ~2ms to parse a 400k character file, and ~0.15ms for incremental updates. It uses indent-aware matching of delimiters and highlights mismatched pairs. See the roadmap for the current status, contributions welcome!

• Works out of the box with no additional configuration
• Rainbow highlighting of pairs
• Indent-aware matching of delimiters to highlight mismatched pairs
• Wrapping via motions (dot-repeatable) or treesitter
• Updates on every keystroke (<0.2ms)

Behavior

The behavior was inspired by lexima.vim and nvim-autopairs
