Installation

IMPORTANT

To avoid breaking changes, it is recommended to pin the plugin to a specific release when installing.

Requirements

• The curl library
• Neovim 0.11.0 or greater
• (Optional) An API key for your chosen LLM
• (Optional) nvim-treesitter and a yaml parser for markdown prompt library items
• (Optional) The file command for detecting image mimetype
• (Optional) The ripgrep library for the grep_search tool

You can run :checkhealth codecompanion to verify that all requirements are met.

Installation

The plugin can be installed with the plugin manager of your choice. It is recommended to pin the plugin to a specific release to avoid breaking changes.

nvim-treesitter is required if you plan to use markdown prompts in the prompt library, ensuring you have the yaml parser installed.

vim.pack

vim.pack.add({ "https://www.github.com/nvim-lua/plenary.nvim" })
vim.pack.add({ "https://github.com/nvim-treesitter/nvim-treesitter" })
vim.pack.add({ {
  src = "https://www.github.com/olimorris/codecompanion.nvim",
  version = vim.version.range("^19.0.0")
} })

-- Somewhere in your config
require("codecompanion").setup()

Lazy.nvim

{
  "olimorris/codecompanion.nvim",
  version = "^19.0.0",
  opts = {},
  dependencies = {
    "nvim-lua/plenary.nvim",
    "nvim-treesitter/nvim-treesitter",
  },
},

Packer.nvim

use({
  "olimorris/codecompanion.nvim",
  tag = "^19.0.0",
  config = function()
    require("codecompanion").setup()
  end,
  requires = {
    "nvim-lua/plenary.nvim",
    "nvim-treesitter/nvim-treesitter",
  },
}),

Plenary.nvim note:

As per #377, if you pin your plugins to the latest releases, ensure you set plenary.nvim to follow the master branch

Extensions

CodeCompanion supports extensions that add additional functionality to the plugin. Below is an example which installs and configures mcphub.nvim:

1. Install

-- Lazy.nvim
{
  "olimorris/codecompanion.nvim",
  dependencies = {
    "ravitemer/mcphub.nvim"
  }
}

2. Configure

require("codecompanion").setup({
  extensions = {
    mcphub = {
      callback = "mcphub.extensions.codecompanion",
      opts = {
        make_vars = true,
        make_slash_commands = true,
        show_result_in_chat = true
      }
    }
  }
})

Visit the extensions documentation to learn more about available extensions and how to create your own.

Other Plugins

CodeCompanion integrates with a number of other plugins to make your AI coding experience more enjoyable. Below are some common lazy.nvim configurations for popular plugins:

render-markdown.nvim

{
  "MeanderingProgrammer/render-markdown.nvim",
  ft = { "markdown", "codecompanion" }
},

markview.nvim

{
  "OXY2DEV/markview.nvim",
  lazy = false,
  opts = {
    preview = {
      filetypes = { "markdown", "codecompanion" },
      ignore_buftypes = {},
    },
  },
},

img-clip.nvim

{
  "HakonHarnes/img-clip.nvim",
  opts = {
    filetypes = {
      codecompanion = {
        prompt_for_file_name = false,
        template = "[Image]($FILE_PATH)",
        use_absolute_path = true,
      },
    },
  },
},

Use render-markdown.nvim or markview.nvim to render the markdown in the chat buffer. Use img-clip.nvim to copy images from your system clipboard into a chat buffer via :PasteImage:

Completion

When in the chat buffer, completion can be used to more easily add editor context, slash commands and tools. Out of the box, the plugin supports completion with both nvim-cmp and blink.cmp. For the latter, on version <= 0.10.0, ensure that you've added codecompanion as a source:

sources = {
  per_filetype = {
    codecompanion = { "codecompanion" },
  }
},

The plugin also supports native completion and coc.nvim.

Help

Consider using the minimal.lua file to troubleshoot, running it with nvim --clean -u minimal.lua.
