🎵 Ch-ch-changes 🎵
Manages the release of a python library.
- auto generates a changelog entry (using github's compare view and commit urls)
- cli that follows semantic versioning principles to auto-increment the library version
- runs the library tests
- test package installation from a tarball and pypi
- uploads to pypi
- tags the github repo
An application wanting to use changes
must meet these requirements:
- on github
setup.py
requirements.txt
CHANGELOG.md
<app_name>/__init__.py
with__version__
and__url__
- supports executing tests with
nosetests
ortox
- we expect
<app_name>
to be the package and module name
Install changes
:
pip install changes
Run the cli:
changes.
Usage:
changes [options] <module_name> changelog
changes [options] <module_name> release
changes [options] <module_name> bump_version
changes [options] <module_name> run_tests
changes [options] <module_name> install
changes [options] <module_name> upload
changes [options] <module_name> pypi
changes [options] <module_name> tag
changes -h | --help
Options:
--new-version=<ver> Specify version.
-p --patch Patch-level version increment.
-m --minor Minor-level version increment.
-M --major Minor-level version increment.
-h --help Show this screen.
--pypi=<pypi> Use alternative package index
--dry-run Prints the commands that would have been executed.
--skip-changelog For the release task: should the changelog be
generated and committed?
--tox Use `tox` instead of the default: `nosetests`
--test-command=<cmd> Command to use to test the newly installed package
--version-prefix=<prefix> Specify a prefix for version number tags
--noinput To be used in conjuction with one of the version
increment options above, this option stops
`changes` from confirming the new version number.
--module-name=<module> If your module and package aren't the same
--requirements=<reqfile> Requirements file name (defaults to requirements.txt)
--debug Debug output.
The commands do the following:
changelog Generates an automatic changelog from your commit messages
bump_version Increments the __version__ attribute of your module's __init__
run_tests Runs your tests with nosetests
install Attempts to install the sdist
tag Tags your git repo with the new version number
upload Uploads your project with setup.py clean sdist bdist_wheel upload
pypi Attempts to install your package from pypi
release Runs all the previous commands
The default workflow is to run the changelog
command to autogenerate
a changelog entry based on your commit messages.
You're probably going to want to edit that a bit, so changes
won't commit it,
unless you're running the release
command.
The remaining tasks can be automated with the release
command (the
--skip-changelog
option prevents release
from regenerating the automatic changelog)
