MkDocs i18n plugin using static translation markdown files

MkDocs static i18n plugin

An MkDocs plugin that helps you support multiple language versions of your site / documentation.

The mkdocs-static-i18n plugin allows you to support multiple languages of your documentation by adding static translation files to your existing documentation pages.

Multi language support is just one .<language>.md file away!

If you want to see how it looks, check out the demo documentation here.

Like what you :eyes:? Give it a :star:!

Language detection logic

This plugin is made to be as simple as possible and will generate a default version of your website + one per configured language on the <language>/ path.

• the default version will use any .md documentation file first and fallback to any .<default_language>.md file found
• the /<language> language versions will use any .<language>.md documentation file first and fallback to any .<default_language>.md file before fallbacking to any default .md file found

Since demonstrations are better than words, check out the demo documentation here which showcases the logic.

Installation

Just pip install mkdocs-static-i18n!

Configuration

Supported parameters:

• default_language (mandatory): ISO-639-1 (2-letter) string
• languages (mandatory): mapping of ISO-639-1 (2-letter) language code: display value
• material_alternate (default: true): boolean - see this section for more info

plugins:
  - i18n:
      default_language: en
      languages:
        en: English
        fr: Français

Example output

Using the configuration above on the following docs/ structure will build the following site/ (leaving out static files for readability):

docs
├── index.fr.md
├── index.md
├── topic1
│   ├── index.en.md
│   └── index.fr.md
└── topic2
    ├── index.en.md
    └── index.md

site
├── en
│   ├── index.html
│   ├── topic1
│   │   └── index.html
│   └── topic2
│       └── index.html
├── fr
│   ├── index.html
│   ├── topic1
│   │   └── index.html
│   └── topic2
│       └── index.html
├── index.html
├── topic1
│   └── index.html
└── topic2
    └── index.html

Not building a dedicated version for the default language

If you do not wish to build a dedicated <language>/ path for the default_language version of your documentation, simply do not list it on the languages list. See issue #5 for more information.

The following configuration:

plugins:
  - i18n:
      default_language: en
      languages:
        fr: Français

Applied on the following structure:

docs
├── index.fr.md
├── index.md
├── topic1
│   ├── index.en.md
│   └── index.fr.md
└── topic2
    ├── index.en.md
    └── index.md

Will build:

site
├── fr
│   ├── index.html
│   ├── topic1
│   │   └── index.html
│   └── topic2
│       └── index.html
├── index.html
├── topic1
│   └── index.html
└── topic2
    └── index.html

Compatibility with other plugins

This plugin is compatible with the following mkdocs plugins:

• MkDocs Material: the search plugin text will be switched automatically to the right language depending on the version you're browsing and the language selector will automatically be setup for you (requires mkdocs-material>=7.1.0)
• MkDocs Awesome Pages Plugin: the page ordering is preserved on the language specific versions of your site

Adding a language selector on your documentation header

Using mkdocs-material site language selector

Starting version 7.1.0, mkdocs-material supports a site language selector configuration.

The mkdocs-static-i18n plugin will detect if you're using mkdocs-material and, if its version is at least 7.1.0, will enable and configure the site language selector automatically for you unless you specified your own extra.alternate configuration!

If you wish to disable that feature, simply set the material_alternate option to false:

plugins:
  - i18n:
      default_language: en
      languages:
        en: English
        fr: Français
      material_alternate: false

Writing a custom language switcher

Let's take mkdocs-material as an example and say we would like to add two buttons to allow our visitors to switch to their preferred language.

The following explanation is showcased in the demo website and you can find the files in this very repository:

• mkdocs.yml
• theme_overrides

We need to add a custom_dir to our theme configuration:

theme:
  name: material
  custom_dir: theme_overrides

Then override the header.html to insert something like:

    {% if "i18n" in config.plugins %}
      <div style="margin-left: 10px; margin-right: 10px;">
          {% include "partials/i18n_languages.html" %}
      </div>
    {% endif %}

And add a i18n_languages.html that could look like this:

{% for lang, display in config.plugins.i18n.config.languages.items() -%}
    <div style="display: inline-block; margin-right:5px;"><a href="/{{ lang }}/">{{ display }}</a></div>
{% endfor %}

The resulting files should be placed like this:

theme_overrides
└── partials
    ├── header.html
    └── i18n_languages.html
