Introduction

This repo hosts my Nvim configuration for Linux, macOS, and Windows. init.lua is the config entry point for terminal Nvim, and ginit.vim is the additional config file for GUI client of Nvim.

My configurations are heavily documented to make it as clear as possible. While you can clone the whole repository and use it, it is not recommended though. Good configurations are personal. Everyone should have his or her unique config file. You are encouraged to copy from this repo the part you want and add it to your own config.

To reduce the possibility of breakage, this config is only maintained for the latest nvim stable release. No effort is spent on maintaining backward compatibility.

Contributing

If you find anything that needs improving, do not hesitate to point it out or create a PR.

If you come across an issue, you can first use :checkhealth command provided by nvim to trouble-shoot yourself. Please read carefully the messages provided by health check.

If you still have an issue, open a new issue.
