Plugin Name: Gitlab REST API Shortcodes
Plugin URI: http://tk-sls.de/ref/gitlab-list-commits
Description: Summary: Embed list of most recent commits to a Gitlab project from a Gitlab instance's public REST API. Example: Add [gitlab-list-commits url=https://tk-sls.de/gitlab project_id=42 commits="all" since="3 month" max=5 releases="latest"] for a list of at most 5 commits to that project that were made since at most 3 months ago, followed by alink to the latest release of the project (if any). To disable the list of commits, set commits="none". To generate a list of all releases, set releases="all". To disable the list of releases, omit the "releases" attribute or set releases="none".
