+# Building TextMate Package via GitHub Actions
+
+This repository includes a GitHub Actions workflow to build TextMate on macOS and create a distributable package.
+
+## How to Trigger the Build
+
+1. Navigate to the **Actions** tab in the GitHub repository
+2. Select the **"Build TextMate Package"** workflow
+3. Click **"Run workflow"**
+4. Choose the build type (release or debug) - defaults to release
+5. Click **"Run workflow"** button
+
+## What the Workflow Does
+
+The workflow performs the following steps:
+
+1. **Environment Setup**:
+   - Checks out the repository with submodules
+   - Sets up Ruby 4.0
+   - Installs required Homebrew dependencies:
+     - boost (portable C++ libraries)
+     - capnp (Cap'n Proto serialization)
+     - google-sparsehash (cache-friendly hash map)
+     - multimarkdown (marked-up plain text compiler)
+     - ninja (build system)
+     - ragel (state machine compiler)
+     - gdbm (GNU Database Manager, needed for Ruby DBM gem)
+
+2. **Ruby Dependencies**:
+   - Runs `bundle install` to install the gems declared in `Gemfile`
+   - Verifies the bundled `dbm` gem can be loaded properly
+
+3. **Build Process**:
+   - Runs `./configure` to check dependencies and generate build files
+   - Executes `ninja TextMate` to build the application
+   - Handles build errors while ignoring warnings (as requested)
+
+4. **Package Creation**:
+   - Locates the built TextMate.app bundle
+   - Copies it to a package directory
+   - Creates a downloadable artifact
+
+## Download the Package
+
+After the workflow completes successfully:
+
+1. Go to the workflow run page
+2. Scroll down to the **Artifacts** section
+3. Download the `textmate-package-<commit-sha>` artifact
+4. Extract the ZIP file to get the TextMate.app bundle
+
+## Build Configuration
+
+- Default build type is **release** (optimized for distribution)
+- Debug builds include additional debugging symbols and sanitizers
+- The build target is `TextMate` which creates the full application bundle
+
+## Requirements Met
+
+This workflow addresses all the requirements from the issue:
+
+- ✅ Manual trigger via `workflow_dispatch`
+- ✅ macOS runner (`macOS-latest`)
+- ✅ All Homebrew dependencies installed
+- ✅ Ruby setup with a Bundler-managed `dbm` gem
+- ✅ Package creation for distribution
+- ✅ Build warnings ignored (errors still cause failure)
+- ✅ Artifact upload for easy download
+
+## Troubleshooting
+
+If the build fails:
+
+1. Check the workflow logs for specific error messages
+2. Verify all dependencies are correctly installed
+3. Check if there are any changes needed to the build configuration
+4. The workflow will list build artifacts even on partial failures

+# TextMate Copilot Instructions
+
+This is the TextMate text editor codebase - a sophisticated macOS text editor with extensible architecture.
+
+## Project Structure
+
+- **Applications/**: Contains the main TextMate app and helper utilities
+- **Frameworks/**: Core C++ and Objective-C++ frameworks providing functionality
+- **PlugIns/**: Plugin modules for extensibility
+- **Shared/**: Common headers and precompiled headers
+- **vendor/**: Third-party dependencies
+
+## Key Technologies
+
+- **Languages**: C++20, Objective-C++, Objective-C
+- **Build System**: Ninja (via custom rave build system)
+- **Platform**: macOS (minimum 14.0)
+- **Architecture**: Framework-based modular design
+
+## Coding Conventions
+
+### C++ Style
+- Use tabs for indentation (tabSize = 3)
+- Prefer `snake_case` for functions and variables
+- Use `PascalCase` for classes and types
+- Namespace everything under appropriate namespaces (`ng`, `bundles`, etc.)
+- Header guards use format: `FILENAME_H_RANDOMID`
+
+### Memory Management
+- Use ARC (Automatic Reference Counting) for Objective-C++
+- Follow RAII patterns for C++
+- Prefer smart pointers when appropriate
+
+### File Extensions
+- `.h` files are treated as Objective-C++ by default
+- `.cc` for C++ implementation
+- `.mm` for Objective-C++ implementation
+- `.m` for Objective-C implementation
+
+## Important Patterns
+
+### Framework Structure
+Each framework typically has:
+- `src/` directory with headers and implementation
+- Public headers exposed through include paths
+- Private implementation details hidden
+
+### Bundle System
+- TextMate uses a bundle system for extensibility
+- Bundles contain commands, snippets, themes, etc.
+- Bundle items are queried using scope selectors
+
+### Editor Architecture
+- Core editing functionality in `ng` namespace
+- Modular design with clipboard, snippets, selection, etc.
+- Event-driven architecture with callbacks
+
+### Build System
+- Uses custom `rave` build configuration files (`.rave`)
+- Ninja backend for actual compilation
+- Debug and release configurations available
+- Per-framework and per-application build targets
+
+## Key Components
+
+### Core Frameworks
+- **editor**: Text editing engine and operations
+- **document**: Document model and management
+- **bundles**: Bundle loading and querying system
+- **selection**: Text selection and ranges
+- **regexp**: Regular expression support
+- **scm**: Source control integration
+- **settings**: Configuration and preferences
+
+### UI Components
+- **OakTextView**: Main text editing view
+- **DocumentWindow**: Document window management
+- **OakAppKit**: Custom AppKit extensions
+- **MenuBuilder**: Dynamic menu construction
+
+## Development Guidelines
+
+### Adding New Features
+1. Consider which framework should contain the functionality
+2. Follow existing patterns for similar features
+3. Update appropriate `.rave` build files
+4. Add tests in `tests/` subdirectories when applicable
+
+### Working with Bundles
+- Bundle items have UUIDs, names, and scope selectors
+- Use `bundles::query()` to find relevant items
+- Commands can transform text, show output, etc.
+
+### Text Processing
+- Use `ng::ranges_t` for text selections
+- Text transformations follow functional patterns
+- Support for snippets with placeholder expansion
+
+### Platform Integration
+- Heavy use of Foundation and AppKit frameworks
+- Custom Objective-C++ wrappers for C++ functionality
+- Native macOS UI patterns and behaviors
+
+## Testing
+- Uses CxxTest framework for unit testing
+- Test files follow `t_*.{cc,mm}` pattern
+- GUI tests use `gui_*.mm` pattern
+- Run tests with `ninja <framework>/test`
+
+## Build Commands
+- `./configure && ninja TextMate/run` - Build and launch TextMate
+- `ninja TextMate` - Build TextMate without launching
+- `ninja <framework>/test` - Run tests for specific framework
+- `ninja -t clean` - Clean build artifacts
+
+When contributing to TextMate, maintain the existing architectural patterns, follow the established coding style, and ensure changes integrate well with the bundle and framework system.
