# Electron Desktop Apps Integration Summary

## Overview

The Tactus Electron desktop apps have been integrated into the main semantic-release workflow. Desktop builds now happen automatically after PyPI publication as part of the standard release process.

## Changes Made

### 1. GitHub Actions Workflow Update

**File**: `.github/workflows/release.yml`

Added a new `desktop-builds` job that:
- Triggers after successful PyPI publication
- Runs in parallel on macOS, Windows, and Linux
- Builds all three desktop installers
- Attaches them to the semantic-release GitHub Release

**Workflow sequence**:
```
quality-checks (ruff, black, pytest, behave)
    ↓
release (semantic-release, PyPI publish)
    ↓
desktop-builds (Mac, Windows, Linux in parallel)
    ↓
Attach installers to GitHub Release
```

### 2. Desktop App Files Created

**Icon files** (`tactus-desktop/resources/`):
- `app-icon.icns` (macOS, 926 KB)
- `app-icon.ico` (Windows, 42 KB)
- `app-icon.png` (Linux, 152 KB)

**Scripts**:
- `tactus-desktop/scripts/generate-icons.sh` - Regenerate icons from source

**Documentation**:
- `tactus-desktop/BUILD_GUIDE.md` - Complete build guide
- `ELECTRON_INTEGRATION.md` (this file) - Integration summary

### 3. PyInstaller Configuration Fix

**File**: `tactus-desktop/backend/tactus_backend.spec`

Added missing data files for behave/gherkin testing:
```python
behave_datas = collect_data_files('behave')
gherkin_datas = collect_data_files('gherkin')
```

## How Releases Work Now

### Automatic Release (Recommended)

1. Make changes and commit with conventional commits:
   ```bash
   git commit -m "feat: add new feature"
   git push origin main
   ```

2. GitHub Actions automatically:
   - Runs all quality checks
   - Publishes to PyPI (if tests pass)
   - Builds desktop apps for all platforms
   - Creates GitHub Release with all artifacts

### Manual Local Build (Development/Testing)

```bash
cd tactus-desktop

# Ensure Python 3.11+
source /opt/anaconda3/etc/profile.d/conda.sh
conda activate py311

# Build everything
npm run build:all

# Package for local platform
npm run package:mac    # macOS
npm run package:win    # Windows
npm run package:linux  # Linux
```

## What Gets Published

Each semantic-release version bump publishes:

1. **Python Package** to PyPI
   ```bash
   pip install tactus=={version}
   ```

2. **Desktop Installers** to GitHub Releases
   - `Tactus IDE-{version}-mac.dmg` (macOS)
   - `Tactus IDE-{version}-arm64.AppImage` (Linux)
   - `Tactus IDE-Setup-{version}.exe` (Windows)

## Build Requirements

### Python
- Version: 3.11+ (conda py311 environment recommended)
- PyInstaller: 6.17.0+
- All tactus dependencies

### Node.js
- Version: 18+
- electron-builder: 24.13.3

### System Tools (macOS only for local builds)
- `iconutil` (built-in on macOS)
- ImageMagick (`brew install imagemagick`)

## Testing the Integration

To test the full workflow:

1. Make a test commit to a branch:
   ```bash
   git checkout -b test-desktop-build
   git commit --allow-empty -m "feat: test desktop build integration"
   git push origin test-desktop-build
   ```

2. Create a PR and merge to main

3. Monitor GitHub Actions:
   - Watch `quality-checks` job complete
   - Watch `release` job publish to PyPI
   - Watch `desktop-builds` matrix jobs build all platforms
   - Verify artifacts appear in GitHub Release

## Troubleshooting

### Desktop builds fail with Python errors

**Issue**: Backend crashes with "ModuleNotFoundError"

**Solution**: Update `tactus-desktop/backend/tactus_backend.spec`:
- Add missing module to `hiddenimports`
- Add missing data files to `datas`
- Rebuild backend: `npm run build:backend`

### Desktop builds fail with "cannot find package.json"

**Issue**: electron-builder running from wrong directory

**Solution**: Ensure `working-directory: ./tactus-desktop` is set in all steps

### Version mismatch between PyPI and desktop apps

**Issue**: Desktop apps have wrong version number

**Solution**: The workflow fetches the latest git tag created by semantic-release. Ensure:
- semantic-release completes successfully
- Git tags are pushed
- Desktop builds checkout the repo after release job

## Old Workflow

The old workflow `.github/workflows/desktop-release.yml` triggered on `desktop-v*` tags. This can now be:
- **Deleted** (desktop builds are integrated into main workflow)
- **Kept** (for manual desktop-only releases if needed)

If keeping it, document that it's for manual desktop-only releases that bypass the standard release process.

## Future Enhancements

Potential improvements for future releases:

1. **Code signing**
   - macOS: Apple Developer ID certificate
   - Windows: Code signing certificate
   - Removes security warnings on first launch

2. **Auto-updates**
   - Implement electron-updater
   - Users get automatic updates without manual download

3. **Smaller bundles**
   - Use Python slim runtime
   - Exclude unnecessary dependencies
   - Could reduce from ~700MB to ~300MB

4. **File associations**
   - Register `.tac` file type
   - Users can double-click .tac files to open in IDE

5. **App Store distribution**
   - macOS App Store
   - Microsoft Store
   - Snap Store (Linux)

## Summary

✅ Desktop builds integrated into semantic-release workflow
✅ Builds trigger automatically after PyPI publish
✅ All three platforms built in parallel (Mac, Windows, Linux)
✅ Installers attached to GitHub Releases automatically
✅ Mac app tested and working locally
✅ Documentation updated

The desktop apps are now part of your standard release process!
