template.render()

It is also possible to specified a branch (or tag) name:

from jinja2 import Environment

env = Environment(extensions=['jinja2_github.GitHubRepoBranchShaExtension'])

# With an explicit branch name -> "cfe12ceefd761502181660de76a8cc5d40d5f31c"
template = env.from_string("{% github_repo_branch_sha 'Slicer/Slicer', 'master-48' %}")

template.render()

The extension comes with a github_repo_description tag that allows to render the description of a GitHub project.

from jinja2 import Environment

env = Environment(extensions=['jinja2_github.GitHubRepoDescriptionExtension'])

template.render()

Maintainer: Making a release

1. Make sure that all CI tests are passing on CircleCI.
2. List all tags sorted by version

$ git tag -l | sort -V

3. Choose the next release version number

$ release=X.Y.Z

Warning

To ensure the packages are uploaded on PyPI, tags must match this regular expression: ^[0-9]+(\.[0-9]+)*(\.post[0-9]+)?$.

4. Download latest sources

$ cd /tmp && \
  git clone git@github.com:jcfr/jinja2-github && \
  cd jinja2-github

5. Update __version__ in jinja2_github.py script.

$ sed -i "5s/.*/__version__ = '$release'/" jinja2_github.py

6. Commit and push the changes

$ git add jinja2_github.py
$ git commit -m "jinja2-github $release"
$ git push origin master

7. Tag the release

$ git tag --sign -m "jinja2-github ${release}" ${release} origin/master

Note

We recommend using a GPG signing key to sign the tag.

8. Publish the release tag

$ git push origin ${release}

Important

This will trigger builds on each CI services and automatically upload the wheels and source distribution on PyPI.

9. Check the status of the builds on CircleCI.
