Everything you need to know about CodeCompanion (installation, configuration and usage) is within the docs.

Before raising an issue, there are a number of steps you can take to troubleshoot a problem:

Checkhealth

Run :checkhealth codecompanion and check all dependencies are installed correctly. Also take note of the log file path.

Turn on logging

Update your config and turn debug logging on:

and inspect the log file as per the location from the checkhealth command.

Try with a minimal.lua file

A large proportion of issues which are raised in Neovim plugins are to do with a user's own config. That's why I always ask users to fill in a minimal.lua file when they raise an issue. We can rule out their config being an issue and it allows me to recreate the problem.

For this purpose, I have included a minimal.lua file in the repository for you to test out if you're facing issues. Simply copy the file, edit it and run neovim with nvim --clean -u minimal.lua.

I am open to contributions but they will be implemented at my discretion. Feel free to open up a discussion before embarking on a PR and please read the CONTRIBUTING.md guide.
