PawToComplete.nvim 🐱

"autocomplete" with a "paw". A lightweight, high-performance Neovim completion and signature help plugin with a C++ core and a fun cat-themed interactive state.

Features

• Blazing Fast: C++ core handles scoring, fuzzy matching, and LFU caching.
• Visual Polish:
  • Rounded borders for completion and signature windows.
  • Clean, modern layout with Nerd Font icons.
  • Ghost text (overlay) preview of completion items.
• Smart Completion:
  • Fuzzy matching using weighted edit distance.
  • Support for completionItem/resolve to fetch on-demand documentation.
  • Markdown rendering in the preview window.
• Signature Help:
  • Active parameter highlighting.
  • Markdown support for documentation.
• Interactive Cat Theme:
  • A digital cat 🐱 that reacts to your typing!
  • The cat's mood changes from happy to pouting or crying based on interaction frequency.
  • View your cat's status in the completion preview window with a star-based scoring system.

Performance

Pawtocomplete uses a custom C++ module (paw.cc) to perform heavy lifting:

• LFU Cache: Efficiently caches LSP results.
• Weighted Edit Distance: Sophisticated scoring algorithm (alpha, beta, gamma weights).
• Fast Lua/C Bridge: Optimized data transfer between Neovim and the C++ core.

Configuration

require('pawtocomplete').setup({
  completion = {
    delay = 200,             -- Debounce delay for completion triggering
    max_cost = 0.9,          -- Maximum cost for filtering items
    insert_cost = 1,         -- Weighted cost for insertions
    delete_cost = 1,         -- Weighted cost for deletions
    substitude_cost = 2,     -- Weighted cost for substitutions
  },
  signature = {
    delay = 100,             -- Debounce delay for signature help
    max_width = 120,
    max_height = 6,
  },
})

Icons

Pawtocomplete uses Nerd Fonts for a premium look. Ensure you have a Nerd Font installed and enabled in your terminal.

Emojis

The cat 🐱 goes through several states:

• Normal typing: 🐱 -> 😺 -> 😸 -> 😽
• Inactivity: 😿 -> 😾 -> 😼

Happy coding! 🐾
