Changelog

Python projects that list slack_cli_hooks, or another spelling of slack-cli-hooks, in requirements.txt or pyproject.toml no longer get a second slack-cli-hooks<1.0.0 dependency added during project initialization with slack create or slack init.

Summary

This pull request recognizes an existing slack-cli-hooks dependency under any normalized Python package name, so spellings like slack_cli_hooks and Slack.CLI-Hooks no longer get a duplicate.

• Python package names that differ only by name normalization are the same package. Matching ignores case and treats any run of -, _, or . as one separator.
• installRequirementsTxt and installPyProjectToml only matched the exact text slack-cli-hooks. The examples in chore: replace requirements.txt with pyproject.toml dependencies slack-samples/bolt-python-examples#337 list "slack_cli_hooks==0.3.0" in pyproject.toml, so the CLI added "slack-cli-hooks<1.0.0" to them as a second entry.
• Both checks now use containsPackage from a new pip.go, next to npm.go in the Node runtime. It normalizes each package name found in the file and compares it with slack-cli-hooks. Version specifiers, extras, and markers after the name don't affect the match, as in slack_cli_hooks[x]>=0.3; python_version>"3.9".

Testing

1. Clone the examples and check out the pull request: gh repo clone slack-samples/bolt-python-examples && cd bolt-python-examples && gh pr checkout 337
2. Go to an example that lists slack_cli_hooks==0.3.0 in pyproject.toml: cd ai/slackbot-mcp-client/no-auth
3. Run slack init with this branch's build. Confirm it prints Found pyproject.toml with slack-cli-hooks, then decline the prompt to link an app.
4. Run git diff pyproject.toml and confirm there are no changes. A build from main adds "slack-cli-hooks<1.0.0", to the dependencies array here.
5. Repeat in a project whose requirements.txt lists slack_cli_hooks==0.3.0 and confirm it prints Found requirements.txt with slack-cli-hooks and leaves the file unchanged.

Notes

• A name anywhere in the file still counts as declared, as with the earlier text match. That includes comments, #egg=slack_cli_hooks fragments, and [tool.poetry.dependencies] keys.
• A package whose name only starts with slack-cli-hooks, such as slack-cli-hooks-example, no longer counts as declared, so slack-cli-hooks<1.0.0 is added next to it.
• Possible follow-up: requirements.txt still looks for the exact text slack-bolt when deciding where to add the hooks line. With slack_bolt, the line is added at the end of the file. This affects placement only, not duplicates.

Requirements

• I've read and understood the Contributing Guidelines and have done my best effort to follow them.
• I've read and agree to the Code of Conduct.

✅ Thanks @zimeg! Really appreciate you chasing this down from the bolt-python-examples changes, the CLI now respects however a project spells slack-cli-hooks.

[mwbrooks]

praise: Matching on normalized names fixes the duplicate slack_cli_hooks entry and also stops counting slack-cli-hooks-extra as declared. Linking the regex and normalizer straight to the packaging spec is a nice touch 📦

🌟 Thanks for the kind review @mwbrooks! Glad the normalized names catch the -extra case too.
