# PyPI Installation Components - Summary

This document summarizes all components prepared for PyPI installation.

## Created Files

### 1. Package Manifest
- **MANIFEST.in**: Defines which additional files to include in the distribution package
  - Documentation files (README.md, README.de.md, LICENSE, CHANGELOG.md)
  - Configuration files (pyproject.toml)
  - Example files (examples/)
  - Excludes development and build files

### 2. Credentials Template
- **.pypirc.example**: Template for PyPI credentials
  - Configuration for both PyPI and Test PyPI
  - Uses API tokens for authentication
  - Instructions included in comments

### 3. Build and Upload Scripts (scripts/)
- **build.sh**: Builds the package for distribution
  - Cleans previous builds
  - Installs/upgrades build tools
  - Creates wheel and source distributions
  - Runs package checks
  
- **upload-testpypi.sh**: Uploads to Test PyPI for testing
  - Validates distribution files exist
  - Uploads to Test PyPI
  - Provides installation test commands
  
- **upload-pypi.sh**: Uploads to production PyPI
  - Includes safety confirmation prompt
  - Validates distribution files exist
  - Uploads to PyPI

### 4. GitHub Actions Workflow
- **.github/workflows/publish-pypi.yml**: Automated publishing
  - Triggers on GitHub releases (for PyPI)
  - Manual trigger option (for Test PyPI)
  - Builds, checks, and publishes package
  - Attaches distribution files to GitHub release

### 5. Documentation
- **PUBLISHING.md**: Complete guide for publishing to PyPI
  - Prerequisites and account setup
  - Credential configuration (local and GitHub Actions)
  - Version management instructions
  - Manual and automated publishing processes
  - Verification steps
  - Troubleshooting guide
  - Pre-release checklist

### 6. Updated .gitignore
- Added `.pypirc` to prevent accidental credential commits

## Existing Configuration (Already in Place)

### pyproject.toml
- ✅ Build system configured (hatchling)
- ✅ Package metadata complete
- ✅ Dependencies listed
- ✅ CLI entry point defined: `vogel-trainer`
- ✅ URLs configured (homepage, repository, issues)
- ✅ Python version: >=3.9
- ✅ Classifiers for PyPI search

### Package Structure
- ✅ `src/vogel_model_trainer/` layout
- ✅ `__version__.py` for version management
- ✅ `__init__.py` with package docstring

## Usage

### Local Publishing

1. **Test Build:**
   ```bash
   ./scripts/build.sh
   ```

2. **Test on Test PyPI:**
   ```bash
   ./scripts/upload-testpypi.sh
   pip install --index-url https://test.pypi.org/simple/ \
               --extra-index-url https://pypi.org/simple/ \
               vogel-model-trainer
   ```

3. **Publish to PyPI:**
   ```bash
   ./scripts/upload-pypi.sh
   ```

### Automated Publishing via GitHub

1. **Create a tag:**
   ```bash
   git tag v0.1.0
   git push origin v0.1.0
   ```

2. **Create GitHub Release:**
   - Go to repository → Releases → "Draft a new release"
   - Select your tag
   - Write release notes
   - Publish

3. **GitHub Actions automatically:**
   - Builds the package
   - Publishes to PyPI
   - Attaches files to release

## Next Steps

1. **Set up PyPI accounts** (if not done):
   - Create PyPI account: https://pypi.org/account/register/
   - Create Test PyPI account: https://test.pypi.org/account/register/
   - Enable 2FA on both

2. **Generate API tokens**:
   - PyPI: Account Settings → API tokens
   - Test PyPI: Account Settings → API tokens

3. **Configure GitHub Secrets** (for automated publishing):
   - Go to repository Settings → Secrets and variables → Actions
   - Add `PYPI_API_TOKEN`
   - Add `TEST_PYPI_API_TOKEN`

4. **Test the build locally:**
   ```bash
   ./scripts/build.sh
   ```

5. **Test on Test PyPI** before production release

## Files to Commit

All created files should be committed to the repository:
- MANIFEST.in

- scripts/build.sh
- scripts/upload-testpypi.sh
- scripts/upload-pypi.sh
- .github/workflows/publish-pypi.yml
- PUBLISHING.md
- .gitignore (updated)
