Catppuccin Mocha Theme - Statuslines

Features

• Official Catppuccin Mocha color palette with 26 eye-candy colors
• Powerline-style separators for seamless segment transitions
• Modular segments: model, directory, Git branch, token count
• Pastel aesthetics optimized for long coding sessions
• Git integration with branch display
• Nerd Font icons for visual clarity
• Conditional rendering (Git segment only in repositories)
• 256-color terminal support for accurate palette reproduction

Use Cases

• Developers already using Catppuccin theme in editor/terminal
• Users preferring soothing pastel aesthetics over harsh neon
• Teams standardizing on Catppuccin design system
• Visual continuity across Neovim, tmux, and Claude Code
• Reducing eye strain during extended AI-assisted coding sessions
• Accessibility-friendly color schemes for low-light environments

Requirements

• Claude Code CLI installed and configured
• Bash shell available (bash 4.0+ recommended for string manipulation)
• jq command-line JSON processor (jq 1.6+ recommended for safe extraction with // defaults)
• Terminal with 256-color mode support (required for accurate Catppuccin Mocha palette reproduction)
• Nerd Font installed and configured (required for Powerline separator glyphs: U+E0B0-U+E0B3)
• Git command-line tool (optional, for Git branch segment display)

Catppuccin Mocha Theme Installation Example

Complete setup script with Nerd Font verification

#!/bin/bash
# Installation script for Catppuccin Mocha Theme

mkdir -p .claude/statuslines

# Check for Nerd Font (Powerline separators require Nerd Font)
echo "Checking for Nerd Font support..."
if echo -e "\ue0b0" | grep -q "\ue0b0"; then
  echo "Nerd Font detected"
else
  echo "Warning: Nerd Font may not be installed. Powerline separators may not display correctly."
  echo "Install from: https://www.nerdfonts.com/"
  echo "Recommended: JetBrains Mono Nerd Font, FiraCode Nerd Font"
fi

# Check terminal color support
echo "Checking terminal color support..."
if tput colors | grep -qE '^(256|[0-9]{3,})$'; then
  echo "256-color mode supported"
else
  echo "Warning: Terminal may not support 256 colors. Colors may appear incorrect."
fi

cat > .claude/statuslines/catppuccin-mocha-theme.sh << 'SCRIPT_EOF'
#!/usr/bin/env bash
# Paste the full statusline script from the primary example above before running this installer.
SCRIPT_EOF

chmod +x .claude/statuslines/catppuccin-mocha-theme.sh

# Add to settings.json
if [ ! -f .claude/settings.json ]; then
  echo '{"statusLine":{"type":"command","command":"$CLAUDE_PROJECT_DIR/.claude/statuslines/catppuccin-mocha-theme.sh","refreshInterval":500}}' > .claude/settings.json

  jq '.statusLine = {"type":"command","command":"$CLAUDE_PROJECT_DIR/.claude/statuslines/catppuccin-mocha-theme.sh","refreshInterval":500}' .claude/settings.json > .claude/settings.json.tmp
  mv .claude/settings.json.tmp .claude/settings.json
fi

echo "Catppuccin Mocha Theme installed successfully!"
echo "Note: For best results, use a terminal with 256-color support and Nerd Font."

Troubleshooting

Colors look washed out or incorrect compared to official palette

Verify terminal supports 256 colors with 'tput colors' (should return 256). Enable true color if available: export COLORTERM=truecolor. Check terminal theme doesn't override ANSI colors. Verify color codes match Catppuccin Mocha palette: LAVENDER=183, BLUE=117, TEAL=152, PEACH=216. Test colors: echo -e '\033[48;5;183m LAVENDER \033[0m'.

Nerd Font icons showing as boxes or missing glyphs

Install Catppuccin-compatible Nerd Font from nerdfonts.com. Recommended: JetBrains Mono Nerd Font, FiraCode Nerd Font. Configure terminal to use installed font in preferences. Verify font includes Powerline glyphs (U+E0B0-U+E0B3). Test separator: echo -e '\ue0b0' (should show Powerline separator, not box).

Git branch not displaying even when in repository

Check Git installed: git --version. Verify you're in Git repo: git status. Ensure script has permission to execute git commands. Test manually: git rev-parse --abbrev-ref HEAD. Check error handling: git_branch=$(git rev-parse --abbrev-ref HEAD 2>/dev/null || echo ""). Verify Git command output is not empty.

Powerline separators misaligned or overlapping text

Verify Nerd Font properly installed with Powerline glyphs (U+E0B0-U+E0B3). Test separator: echo -e '\ue0b0'. Disable font ligatures if enabled. Increase terminal line spacing if needed. Check terminal font rendering settings. Verify separator character encoding: SEP="\ue0b0" (Unicode escape).

Statusline disappears or flickers on refresh

Increase refreshInterval to 1000ms in configuration: {"refreshInterval": 1000}. Check script permissions: chmod +x statusline.sh. Verify jq installed: jq --version. Test script manually with sample JSON input. Check for syntax errors: bash -n catppuccin-mocha-theme.sh.

Model or directory showing as 'unknown' or empty

Verify JSON structure: echo '$input' | jq '.model, .workspace'. Check field names: model.id, model.display_name, workspace.current_dir, workspace.project_dir. Test extraction: echo '$input' | jq -r '.model.id // .model.display_name // "unknown"'. Verify Claude Code is passing correct JSON structure.

Token count always showing 0

Check token field exists: echo '$input' | jq '.session.totalTokens, .cost.total_tokens'. Verify field name matches: session.totalTokens or cost.total_tokens. Test extraction: echo '$input' | jq -r '.session.totalTokens // .cost.total_tokens // 0'. Check Claude Code version supports token tracking.

Statusline output showing raw ANSI codes instead of colors

Verify echo -e flag is used for escape sequence interpretation. Check terminal supports ANSI colors: echo -e '\033[38;5;183mLAVENDER\033[0m'. Some terminals require explicit color support enabled. Check TERM environment variable: echo $TERM (should include 'xterm' or '256color'). Verify terminal emulator settings for color support.
