Features

• Treesitter Powered: Smartly extracts function signature, docstrings, and context.
• Async & Non-blocking: Uses plenary.curl to fetch completions without freezing the editor.
• AI Backend Agnostic: Works with any OpenAI-compatible API (Ollama, LocalAI, etc.).

Installation

Dependencies

• nvim-treesitter
• plenary.nvim

vim.pack

vim.pack.add({
  "https://github.com/nvim-lua/plenary.nvim",
  "https://github.com/nvim-treesitter/nvim-treesitter",
  "https://github.com/whleucka/bodybuilder.nvim"
})

require("bodybuilder").setup({
  model = "gemma3:270m",  -- Matches the name from your ollama list (also works with ollama cloud)
  keymap = "<leader>ab",
})

Usage

1. Move cursor to any line inside a function definition.
2. Press <leader>ab (or your configured keymap).
3. Wait for the spinner to finish.
4. The body will be replaced with the AI generated code.

Configuration

Default options:

require("bodybuilder").setup({
  url = "http://localhost:11434/api/generate", -- Endpoint (Ollama default)
  model = "llama3", -- See https://github.com/ollama/ollama?tab=readme-ov-file#model-library
  prompt_template = "...", -- See config.lua for default
  keymap = nil, -- Set to string (e.g. '<leader>ab') to auto-register
  timeout = 10000, -- Timeout in milliseconds (default: 10000)
})
