Development

Development setup, project structure, and API documentation for ccstatusline.

If you want the main project overview, return to README.md.

Prerequisites

• Bun (v1.0+)
• Git
• Node.js 14+ (optional, for running the built dist/ccstatusline.js binary or npm publishing)

Setup

# Clone the repository
git clone https://github.com/sirmalloc/ccstatusline.git
cd ccstatusline

# Install dependencies
bun install

Development Commands

# Run in TUI mode
bun run start

# Test piped mode with example payload
bun run example

# Run tests
bun test

# Run typecheck + eslint checks without modifying files
bun run lint

# Apply ESLint auto-fixes intentionally
bun run lint:fix

# Build for distribution
bun run build

# Generate TypeDoc documentation
bun run docs

Configuration Files

• ~/.config/ccstatusline/settings.json - ccstatusline UI/render settings
• ~/.claude/settings.json - Claude Code settings (statusLine command object)
• ~/.cache/ccstatusline/block-cache-*.json - block timer cache (keyed by Claude config directory hash)
• ~/.cache/ccstatusline/compaction/compaction-*.json - per-session compaction counter state

If you use a custom Claude config location, set CLAUDE_CONFIG_DIR and ccstatusline will read/write that path instead of ~/.claude.

Build Notes

• Build target is Node.js 14+ (dist/ccstatusline.js)
• During install, ink@6.2.0 is patched to fix backspace handling on macOS terminals

API Documentation

Complete API documentation is generated using TypeDoc and includes detailed information about:

• Core Types: Configuration interfaces, widget definitions, and render contexts
• Widget System: All available widgets and their customization options
• Utility Functions: Helper functions for rendering, configuration, and terminal handling
• Status Line Rendering: Core rendering engine and formatting options

Generating Documentation

To generate the API documentation locally:

# Generate documentation
bun run docs

# Clean generated documentation
bun run docs:clean

The documentation will be generated in the typedoc/ directory and can be viewed by opening typedoc/index.html in your web browser.

Documentation Structure

• Types: Core TypeScript interfaces and type definitions
• Widgets: Individual widget implementations and their APIs
• Utils: Utility functions for configuration, rendering, and terminal operations
• Main Module: Primary entry point and orchestration functions
