Configuration

Steps to configure Zsh, Ghostty, Neovim, Lazy, Prettier, and Tmux.

1. Clone the Configuration Repository

git clone https://github.com/michaeljymsgutierrez/bashrc-cg ~/bashrc-cg

2. Install Fonts

Required for Ghostty and Neovim icons to render correctly.

cp ~/bashrc-cg/fonts/*.ttf ~/Library/Fonts/

3. Install fzf (Optional)

brew install fzf

4. Configure Zsh

Add to ~/.zshrc:

source ~/bashrc-cg/path.cgf
source ~/bashrc-cg/prompt.cgf
source ~/bashrc-cg/alias.cgf

5. Configure Ghostty

Add to ~/.config/ghostty/config:

config-file = "~/bashrc-cg/ghostty.cgf"

Custom GLSL shaders are available in shaders/. To enable one, uncomment the relevant custom-shader line in ghostty.cgf.

6. Configure Neovim

Add to ~/.config/nvim/init.lua:

local homeDirectory = os.getenv('HOME') .. '/bashrc-cg/nvim-cgf.lua'
local initNvimConfig = loadfile(homeDirectory)
if initNvimConfig then initNvimConfig() end

7. Configure Tmux

Add to ~/.tmux.conf:

source ~/bashrc-cg/tmux.cgf

The color theme (tmux-colors/cg-theme.tmux) is automatically sourced by tmux.cgf - no extra step needed.

8. Global Tooling Configs

cat ~/bashrc-cg/prettier.cgf > ~/.prettierrc
cat ~/bashrc-cg/lazy-lock.cgf > ~/.config/nvim/lazy-lock.json
cat ~/bashrc-cg/gitignore-global.cgf > ~/.gitignore_global
git config --global core.excludesfile ~/.gitignore_global

9. Claude Code Config

git clone https://github.com/michaeljymsgutierrez/cg-claude ~/cg-claude
cd ~/cg-claude && ./pull.sh

pull.sh copies CLAUDE.md, skills/, and plugins/known_marketplaces.json from the repo into ~/.claude/. Run ./push.sh to sync changes back to the repo.
