Dotfiles (Ghostty + Tmux + Neovim)

My personal configuration files for macOS, featuring a high-performance setup with Ghostty, Tmux, and Neovim.

The visual style is unified around the Catppuccin theme.

Step 1: Install Homebrew and Dependencies

• a. Install Homebrew

  /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"

• b. Clone Dotfiles

  git clone https://github.com/jmuncor/.dotfiles.git ~/.dotfiles

• c. Install Dependencies

  cd ~/.dotfiles
  brew bundle

Step 2: Link Configuration Files

Link the config files from the dotfiles folder to your system configuration.

# 1. Ghostty
mkdir -p ~/.config/ghostty
rm -f ~/.config/ghostty/config
ln -s ~/.dotfiles/ghostty/config ~/.config/ghostty/config

# 2. Tmux
mkdir -p ~/.config/tmux
rm -f ~/.tmux.conf
rm -f ~/.config/tmux/tmux.conf
ln -s ~/.dotfiles/tmux/tmux.conf ~/.config/tmux/tmux.conf

# 3. Nvim
rm -rf ~/.config/nvim
ln -s ~/.dotfiles/nvim ~/.config/nvim

# 4. Karabiner
mkdir -p ~/.config/karabiner
rm -f ~/.config/karabiner/karabiner.json
ln -s ~/.dotfiles/karabiner/karabiner.json ~/.config/karabiner/karabiner.json

# 5. Yazi
mkdir -p ~/.config/yazi
rm -f ~/.config/yazi/theme.toml
ln -s ~/.dotfiles/yazi/theme.toml ~/.config/yazi/theme.toml

# 6. Starship
rm -f ~/.config/starship.toml
ln -s ~/.dotfiles/zsh/starship.toml ~/.config/starship.toml

Step 3: Configure Zsh

Add this line to your ~/.zshrc:

source ~/.dotfiles/zsh/config.zsh

Then reload:

source ~/.zshrc

Step 4: Install Tmux Plugin Manager (TPM)

git clone https://github.com/tmux-plugins/tpm ~/.config/tmux/plugins/tpm

Activate Plugins:

1. Open Tmux: tmux
2. Press Ctrl + b then Shift + i to install plugins.

Step 5: First Neovim Launch

Open Neovim (nvim). It will automatically:

• Install lazy.nvim plugin manager
• Download and install all plugins
• Install LSP servers via Mason (pyright, typescript-language-server)

Run :checkhealth to verify the setup.
