vdt.version 0.0.2

repo-version-inc

This tool will automatically increment the version in a repo.

Each succesful build will create a tag. A package can be built from a tag.

usage: version [-h] [-p] [-m] [-M] [-b] [-B BUILD_NUMBER] [-c CHANGELOG]
                   [-n] [--plugin PLUGIN] [--skip-build] [--skip-tag] [-v]

Version increment tool for GIT repositories

optional arguments:
  -h, --help            show this help message and exit
  -p, --patch           increment the patch number
  -m, --minor           increment minor number
  -M, --major           increment major number
  -b, --build           increment build number
  -B BUILD_NUMBER, --build-number BUILD_NUMBER
                        create a tag with this exact build number
  -c CHANGELOG, --changelog CHANGELOG
                        description of the changes in the new version
  -n, --dry-run         don't perform any changes
  --plugin PLUGIN       The plugin used to get the version and build the
                        package
  --skip-build          tag only, don't build
  --skip-tag            build only, don't tag
  -v, --verbose         more output

Jenkins

This tool is to be used in a jenkins build to automate versioning and packaging.

# tag foo
cd $WORKSPACE/src/foo
$WORKSPACE/bin/version -v --build-number=$1 --plugin=debianize --skip-build
git push --tags

# build foo package and upload needed files
cd $WORKSPACE/src/foo
fakeroot $WORKSPACE/bin/version -v --plugin=debianize --skip-tag
upload python-foo_*.deb
upload python-foo.d*.deb
upload python-puka_*.deb

Plugins

With plugins the version tool can be taught how to version or package your repositories.

Create a new python package in the vdt.versionplugin namespace and implement any of the following methods:

def get_version() (must return am vdt.versionplugin.shared.Version object)
def set_version(version) (must return am vdt.versionplugin.shared.Version object)
def build_package(version)
def set_package_version(version)

Implementing these methods is optional. The ones you don’t implement will be taken from https://github.com/devopsconsulting/vdt.versionplugin.default (WIP)

A good example of a plugin that has packaging covered is: https://github.com/devopsconsulting/vdt.versionplugin.debianize

If your plugin is called balla it should live in a package called vdt.versionplugin.balla.

The above four methods, if implemented will be imported like this:

from vdt.versionplugin.balla imported get_version

Extra arguments

When writing a plugin, it might be useful to have some extra arguments, which are passed to your plugin. Rest assured, that is possible. Any argument unknown to vdt.version will be available in the Version object passed to set_version, build_package and set_package_version.

That means in your plugin you can do something like:

import argparse
plugin_arg_parser = argparse.ArgumentParser(description="Weeping plugin")
plugin_arg_parser.p.add_argument("-Q", "--qq", help="Makes the plugin cry")

def build_package(version):
    plugin_args = plugin_arg_parser.parse_args(version.extra_args)
    # do something and have args parsed!
