mkdocs-git-authors-plugin

Lightweight MkDocs plugin to display git authors of a markdown page:

Authors: Jane Doe, John Doe

The plugin only considers authors of the current lines in the page ('surviving code' using git blame).

Other MkDocs plugins that use information from git:

• mkdocs-git-revision-date-localized-plugin for displaying the last revision date
• mkdocs-git-committers-plugin for displaying authors' github user profiles

Setup

Install the plugin using pip3:

pip3 install mkdocs-git-authors-plugin

Next, add the following lines to your mkdocs.yml:

plugins:
  - search
  - git-authors

If you have no plugins entry in your config file yet, you'll likely also want to add the search plugin. MkDocs enables it by default if there is no plugins entry set.

Usage

In markdown pages

You can use the following jinja tags to insert content into your markdown pages:

• {{ git_page_authors }} a summary of the authors of a page. Output wrapped in <span class='git-page-authors'>
• {{ git_site_authors }} a summary of all authors of all pages in your site. Output wrapped in <span class='git-site-authors'>

For example, adding {{ git_page_authors }} will insert:

<span class='git-page-authors'><a href='mailto:[email protected]'>Jane Doe</a><a href='mailto:[email protected]'>John Doe</a></span>

Which renders as:

Jane Doe, John Doe

In theme customizations

MkDocs offers possibilities to customize an existing theme.

As an example, if you use mkdocs-material you can implement git-authors by overriding a template block:

1. Create a new file main.html in docs/theme:

{% extends "base.html" %}

{% block disqus %}
    <div class="md-source-date">
    <small>
        Authors: {{ git_page_authors }}
    </small>
  </div>
    {% include "partials/integrations/disqus.html" %}
{% endblock %}

2. In mkdocs.yml make sure to specify the custom directory with the theme overrides:

theme:
    name: material
    custom_dir: docs/theme/

In theme templates

To add more detailed git author information to your theme you can customize a MkDocs theme or even develop your own.

When enabling this plugin, you will have access to the jinja2 variable git_info which contains as dict with the following structure:

{
  'page_authors' : [
    {
    'name' : 'Jane Doe',
    'email' : '[email protected]',
    'last_datetime' : datetime.datetime(),
    'lines' : 200,
    'contribution' : '40.0%'
  },
  {
    'name' : 'John Doe',
    'email' : '[email protected]',
    'last_datetime' : datetime.datetime(),
    'lines' : 300,
    'contribution' : '60.0%'
  }
 ],
 'site_authors' : # same structure
}

Example usage in theme development

An example of how to use in your templates:

{% if git_info %}
  {%- for author in git_info.get('page_authors') -%}
    <a href="{{ author.email }}" title="{{ author.name }}">
      {{ author.name }}
    </a>,
  {%- endfor -%}
{% endif %}

Alternatively, you could use the simple pre-formatted {{ git_page_authors }} to insert a summary of the authors.

Options

show_contribution

If this option is set to true (default: false) the contribution of a author is printed as a percentage of (source file) lines per author. The output is suppressed if there is only one author for a page.

Example output:

• Authors: John Doe (33.33%), Jane Doe (66.67%) (more than one author)
• Authors: John Doe (one author)

show_line_count

If this option is set to true (default: false) the number of lines per author is shown.

count_empty_lines

If this option is set to true (default: false) empty lines will count towards an authors' contribution.

Tricks

Aggregating Authors

In some repositories authors may have committed with differing name/email combinations. In order to prevent the output being split it is possible to aggregate authors on arbitrary elements by providing a file .mailmap in the repository's root directory. This is a feature of Git itself. The following example will aggregate the contributions of Jane Doe committed under two email addresses:

# .mailmap
Jane Doe <[email protected]> <[email protected]>

This will map commits made with the private-email.com to the company address. For more details and further options (e.g. mapping between different names or misspellings etc. see the git-blame documentation.
