Cookiecutter template for creating new Click command-line tools.
Use this template on your own machine with cookiecutter, or create a brand new repository based on this template entirely through the GitHub web interface using click-app-template-repository.
You'll need to have cookiecutter installed. I recommend pipx for this:
pipx install cookiecutter
Regular pip will work OK too.
Three examples of tools that were initially created using this template:
- shot-scraper: A comand-line utility for taking automated screenshots of websites
- s3-credentials: A tool for creating credentials for accessing S3 buckets
- git-history: Tools for analyzing Git history using SQLite
Run cookiecutter gh:simonw/click-app and then answer the prompts. Here's an example run:
$ cookiecutter gh:simonw/click-app
app_name []: click app template demo
description []: Demonstrating https://github.com/simonw/click-app
hyphenated [click-app-template-demo]:
underscored [click_app_template_demo]:
github_username []: simonw
author_name []: Simon Willison
I strongly recommend accepting the suggested value for "hyphenated" and "underscored" by hitting enter on those prompts.
This will create a directory called click-app-template-demo - the tool name you enter is converted to lowercase and uses hyphens instead of spaces.
See https://github.com/simonw/click-app-template-demo for the output of this example.
Having created the new structure from the template, here's how to start working on the tool.
If your tool is called my-new-tool, you can start working on it like so:
cd my-new-tool
# Create and activate a virtual environment:
python3 -m venv venv
source venv/bin/activate
# Install dependencies so you can edit the project:
pip install -e '.[test]'
# With zsh you have to run this again for some reason:
source venv/bin/activate
# Confirm your tool can be run from the command-line
my-new-tool --version
You should see the following:
my-new-tool, version 0.1
You can run the default test for your tool like so:
pytest
This will execute the test in tests/test_my_new_tool.py.
Now you can open the my_new_tool/cli.py file and start adding Click commands and groups.
You can initialize a Git repository for your tool like this:
cd my-new-tool
git init
git add .
git commit -m "Initial structure from template"
# Rename the 'master' branch to 'main':
git branch -m master main
Use https://github.com/new to create a new GitHub repository sharing the same name as your tool, which should be something like my-new-tool.
Push your main branch to GitHub like this:
git remote add origin [email protected]:YOURNAME/my-new-tool.git
git push -u origin main
The template will have created a GitHub Action which runs your tool's test suite against every commit.
The template also includes a publish.yml GitHub Actions workflow for publishing packages to PyPI, using pypa/gh-action-pypi-publish.
To use this action, you need to create a PyPI account and configure a Trusted Publisher for this package.
Once you have created your account, navigate to https://pypi.org/manage/account/publishing/ and create a "pending publisher" for the package. Use the following values:
- PyPI Project Name: The name of your package
- Owner: Your GitHub username or organization - the "foo" in
github.com/foo/bar - Repsitory name: The name of your repository - the "bar" in
github.com/foo/bar - Workflow name:
publish.yml - Environment name:
release
Now, any time you create a new "Release" on GitHub the Action will build your package and push it to PyPI.
The tag for your release needs to match the VERSION string at the top of your pyproject.toml file. You should bump this version any time you release a new version of your package.
