Usage

This guide provides detailed steps on how to create a Python package, configure it for distribution, and manage its versioning and releases. First, install cookiecutter and bump-my-version and then follow the steps below.

pip install cookiecutter bump-my-version

1. Create the Package Structure

Use cookiecutter to create a package structure. cookiecutter is a command-line utility that creates projects from templates.

cookiecutter gh:opengeos/cookiecutter-pypackage

2. Initialize and Commit to Git

Navigate to your project directory and initialize a Git repository:

cd your-package-name
git init
git add .
git commit -m "Initial commit"

3. Create a Repository on GitHub

• Go to GitHub and create a new empty repository.
• Do NOT initialize it with a README, license, or .gitignore file.

4. Add Git Remote

Link your local repository to the GitHub repository. If your git branch is named main, use the following commands:

git remote add origin [your-repository-url]
git branch -M main
git push -u origin main

If your git branch is named master, use the following commands:

git remote add origin [your-repository-url]
git branch -M master
git push -u origin master

5. Configure GitHub Actions

Change the GitHub Actions settings in your repository to allow read and write operations:

• Go to your repository on GitHub.
• Click on Settings > Actions > General > Workflow permissions.
• Change the settings to allow read and write operations.

6. Push to GitHub

Push your local changes to GitHub:

git push

7. Create an API Token on PyPI

• Visit pypi.org and log in or create an account.
• Navigate to Account Settings > API Tokens.
• Create a new API token. Select Entire account as the scope. Copy the token.

8. Add GitHub Repository Secrets

Add your PyPI credentials as secrets in your GitHub repository:

• Go to your repository on GitHub.
• Click on Settings > Secrets > New repository secret.
• Add PYPI_USERNAME as a secret. Use __token__ as the value.
• Add PYPI_PASSWORD as a secret. Use the API token created above as the password.

9. Make a Release on GitHub

Create a release on GitHub to trigger the deployment of your package:

• Go to the Releases section in your GitHub repository.
• Click Draft a new release.
• Follow the prompts to create the release.

10. Enable GitHub Pages

• Navigate to Settings > Pages.
• Select the gh-pages branch as the source.
• Click Save.

11. Version Management with bump-my-version

Use bump-my-version for managing the version of your package:

• First, do a dry run to see what changes will be made:

bump-my-version bump [patch/minor/major] --dry-run --verbose

• If satisfied, apply the version bump:

bump-my-version bump [patch/minor/major]

12. Push Tags and Changes to GitHub

After bumping the version, push the tags and changes:

git push --tags
git push

13. Make a New Release on GitHub

Finally, make a new release on GitHub with the updated version:

• Repeat the process described in step 9.

Remember to replace placeholders (like your-package-name and [your-repository-url]) with actual values relevant to your package. This guide assumes basic familiarity with Git, GitHub, and Python packaging conventions.
