Ghostty Terminal Configuration

Guide for configuring Ghostty terminal emulator with local documentation access.

When to Use This Skill

Use this skill when:

  • Working with Ghostty configuration files
  • Looking up valid configuration options
  • Troubleshooting Ghostty settings
  • Finding available fonts or themes
  • Understanding Ghostty-specific features

Quick Reference

Access Local Documentation

Ghostty includes comprehensive built-in documentation:

Full configuration reference with inline docs:

bash
ghostty +show-config --default --docs

List available fonts:

bash
ghostty +list-fonts

Search for specific config options:

bash
ghostty +show-config --default --docs | grep -A 10 "keyword"

Configuration File Location

In this dotfiles repository, Ghostty config is managed at:

  • Source: config/ghostty/config
  • Installed: ~/.config/ghostty/config

Common Configuration Patterns

Font configuration:

bash
# List available fonts first
ghostty +list-fonts

# Then configure in config file
font-family = Maple Mono NF
font-size = 14

Theme/Colors:

bash
# Search for color-related options
ghostty +show-config --default --docs | grep -i "color"

Key bindings:

bash
# Search for keybind options
ghostty +show-config --default --docs | grep -i "keybind"

Searching Documentation

Find specific option documentation:

bash
# Example: Find all font-related options
ghostty +show-config --default --docs | grep -B 2 -A 20 "^font-"

Search by keyword:

bash
# Example: Find clipboard options
ghostty +show-config --default --docs | grep -i "clipboard" -A 10

List all available options:

bash
# Get just the config keys without docs
ghostty +show-config --default | grep "^[a-z]" | cut -d= -f1

Validation

Test configuration syntax:

bash
# Ghostty will report errors on startup
ghostty --config-file=path/to/config

View current configuration:

bash
# Shows active config (after applying defaults + user config)
ghostty +show-config

Common Configuration Categories

Key categories (use documentation search for complete details):

  • Font: font-family, font-size, font-style, font-feature
  • Colors: background, foreground, palette, theme
  • Window: window-padding-x/y, window-theme, window-decoration
  • Shell: shell-integration-features, command, working-directory
  • Keybinds: keybind = trigger=action[:parameter]
  • Bell: bell-features, bell-audio-path, bell-audio-volume
  • Performance: renderer, vsync
  • macOS: macos-titlebar-style, macos-option-as-alt

Example: Adding a Font

  1. List available fonts:

    bash
    ghostty +list-fonts | grep -i "JetBrains"
    
  2. Check font configuration docs:

    bash
    ghostty +show-config --default --docs | grep -A 40 "^font-family"
    
  3. Add to config:

    font-family = JetBrains Mono
    font-family = Apple Color Emoji  # Fallback for emoji
    font-size = 14
    
  4. Reload config (Ghostty auto-reloads, or use ctrl+c>r keybind if configured)

Example: Custom Keybindings

  1. Find keybind documentation:

    bash
    ghostty +show-config --default --docs | grep -B 10 -A 30 "^keybind ="
    
  2. Keybind syntax:

    keybind = [prefix:]trigger=action[:parameter]
    
  3. Add custom bindings:

    keybind = ctrl+shift+c=copy_to_clipboard
    keybind = ctrl+shift+v=paste_from_clipboard
    keybind = ctrl+c>v=new_split:right
    

Example: Configuring Bell

  1. Search bell documentation:

    bash
    ghostty +show-config --default --docs | grep -A 50 "^# Bell features"
    
  2. Available bell features:

    • system - System notification (GTK only)
    • audio - Custom sound (GTK only)
    • attention - Bounce dock icon on macOS (default: enabled)
    • title - Add 🔔 emoji to title (default: enabled)
    • border - Display border (GTK only)
  3. Configure bell:

    # Only show title emoji, no dock bounce
    bell-features = no-attention,title
    

Configuration Format

Basic syntax:

# Comments start with hash
key = value

# Boolean values
some-feature = true
other-feature = false

# Multiple values - repeat the key
font-family = JetBrains Mono
font-family = Apple Color Emoji

# Empty value = use default
font-family =

No quotes needed for most values (unlike TOML/YAML):

# Correct
font-family = JetBrains Mono

# Also works, but unnecessary
font-family = "JetBrains Mono"

Keybind prefixes:

  • global: - System-wide (requires accessibility permissions)
  • all: - Apply to all surfaces
  • unconsumed: - Pass to program if not consumed
  • performable: - Only if action can be performed

Tips

  • Ghostty automatically reloads configuration on file changes
  • Use ghostty +show-config to verify active settings
  • All documentation is built-in - no internet required
  • Config format is custom (not TOML/YAML/INI)
  • Comments start with #
  • Boolean values: true or false
  • Multiple values: repeat the key multiple times
  • Empty value (key =) means "use default"

Troubleshooting

Config not loading:

  • Check file location: ~/.config/ghostty/config
  • Verify syntax: generally no quotes needed
  • Check Ghostty logs for errors
  • Unknown fields are silently ignored

Font not found:

  • Use ghostty +list-fonts to find exact font name
  • Names are case-sensitive
  • Some fonts require full family name (e.g., "Maple Mono NF" not "Maple Mono")

Colors not working:

  • Verify hex format: #RRGGBB or #RRGGBBAA
  • Check terminal theme compatibility
  • Use ghostty +show-config to see active values

Keybindings not working:

  • Check for conflicts with system/other apps
  • Verify action name is correct (use docs to find valid actions)
  • Some actions are platform-specific (GTK only, macOS only)
  • Global keybinds require accessibility permissions

Additional Resources
