CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

This is a personal VSCode configuration repository (vscode-siren) that provides a unified configuration for VSCode-based editors including Cursor, VSCode, VSCode Insiders, and Windsurf. It focuses on recreating an Emacs-like text editor experience with custom keybindings, settings, and extensions.

Key Commands

Configuration Management

./siren <editor> config - Create symlinks for editor config files
./siren <editor> extensions - Install extensions from lock file
./siren <editor> extensions --latest - Install latest versions of extensions
./siren <editor> dump-extensions - Export installed extensions to lock file

Makefile Shortcuts

make cursor-config - Configure Cursor editor
make cursor-extensions - Install Cursor extensions
make all-config - Configure all editors
make all-extensions - Install extensions for all editors

Supported Editors

cursor (c) - Cursor editor
vscode (code, vsc, v) - Visual Studio Code
vscode-insiders (vsci, i) - Visual Studio Code Insiders
windsurf (surf, w) - Windsurf editor

Architecture

Core Components

siren script - Main configuration management tool (bash script)
settings.json - VSCode settings configuration
keybindings.json - Custom keybindings (Emacs-inspired)
snippets/ - Code snippets for Go and Ruby
extensions.*.lock - Extension lock files for each editor

Configuration Structure

Config files are symlinked to appropriate editor directories based on OS
Extensions are managed via lock files with version pinning
Cursor uses .vsix installation due to signature verification issues
Static symlinks for additional files like cspell dictionary and MCP config

Key Features

Cross-platform support (macOS/Linux)
Version-locked extensions with fallback to .vsix downloads
Automatic backup of existing configurations
Emacs-inspired keybindings and workflow
Dark/light theme switching based on system preferences

Development Guidelines

Based on cursor/user-rules.md:

Keep line length to 80 characters when possible
Check Makefile for common project tasks
Be direct and terse in communication
Provide code solutions rather than general advice
Include robust error handling
Consider cross-platform compatibility
Respect existing code comments
