Development

poetry is a required package to develop.

$ git clone https://github.com/tmux-python/libtmux.git

$ cd libtmux

$ poetry install -E "docs test coverage lint"

Makefile commands prefixed with watch_ will watch files and rerun.

Tests

poetry run py.test

Helpers: make test Rerun tests on file change: make watch_test (requires entr(1))

Pytest plugin

See tmux pytest plugin.

Documentation

Default preview server: http://localhost:8023

sphinx-autobuild will automatically build the docs, watch for file changes and launch a server.

From home directory: make start_docs From inside docs/: make start

Manual documentation (the hard way)

cd docs/ and make html to build. make serve to start http server.

Helpers: make build_docs, make serve_docs

Rebuild docs on file change: make watch_docs (requires entr(1))

Rebuild docs and run server via one terminal: make dev_docs (requires above, and a make(1) with -J support, e.g. GNU Make)

Releasing

Since this software is used by tens of thousands of users daily, we don’t want to release breaking changes. Additionally this is packaged on large Linux/BSD distros, so we must be mindful of architectural changes.

Choose what the next version is. Assuming it’s version 0.9.0, it could be:

• 0.9.0post0: postrelease, if there was a packaging issue

• 0.9.1: bugfix / security / tweak

• 0.10.0: breaking changes, new features

Let’s assume we pick 0.9.1

CHANGES: Assure any PRs merged since last release are mentioned. Give a thank you to the contributor. Set the header with the new version and the date. Leave the “current” header and Insert changes/features/fixes for next release here at the top::

current
-------
- *Insert changes/features/fixes for next release here*

libtmux 0.9.1 (2020-10-12)
--------------------------
- :issue:`1`: Fix bug

libtmux/__init__.py and __about__.py - Set version

$ git commit -m 'Tag v0.9.1'

$ git tag v0.9.1

After git push and git push --tags, CI will automatically build and deploy to PyPI.

Releasing with Poetry (manual)

This isn’t used yet since package maintainers may want setup.py in the source. See https://github.com/tmux-python/tmuxp/issues/625.

As of 0.10, poetry handles virtualenv creation, package requirements, versioning, building, and publishing. Therefore there is no setup.py or requirements files.

Update __version__ in __about__.py and pyproject.toml::

git commit -m 'build(libtmux): Tag v0.1.1'
git tag v0.1.1
git push
git push --tags
poetry build
poetry deploy
