Documents from Git

Official documentation: https://github.com/gis-ops/wordpress-markdown-git This WordPress Plugin lets you easily publish, collaborate on and version control your [Markdown, Jupyter notebook] documents directly from your favorite remote Git platform, even if it's self-hosted. The advantages are:

• Write documents in your favorite editor and just push to your remote repository to update your blog instantly
• Use the power of version control: publish different versions of the document in different posts, i.e. from another branch or commit than latest master
• Easy to update by your readers via pull requests, minimizing the chance of stale tutorials

The following document types are currently supported:

• Markdown
• Jupyter notebooks (only for public repositories)

The following platforms are currently supported:

• Github
• Bitbucket
• Gitlab

Usage Note, this plugin uses Github's wonderful /markdown API to render to HTML. This comes with 2 caveats:

1. Unless authenticated, the rate limit is set at 60 requests per minute. Since v1.1.0 the plugin is capable of statically caching content. In case that's not dynamic enough for you, your only option currently is to not use any cache in which case every document will be pulled from your provider every time someone opens it on your site. Then it's strongly recommended to create a Github access token and register it with the plugin. Then the rate limit will be set to 5000 requests per hour. See Global attributes section for details on how to do that.
2. The Markdown content cannot exceed 400 KB, so roughly 400 000 characters incl whitespace. If not a monographic dissertation, this should not be an applicable limit though.

Shortcodes The plugin features a variety of shortcodes. Publish documents The document-specific shortcodes follow a pattern of [git-<platform>-<action>], where

• <platform> can be one of
• github: if you use Github as your VCS platform
• bitbucket: if you use Bitbucket as your VCS platform
• gitlab: if you use Gitlab as your VCS platform
• <action> can be one of
• markdown: Render your Markdown files hosted on your VCS platform in Github's rendering style
• jupyter: Render your Jupyter notebook hosted on your VCS platfrom (only for public repositories)
• checkout: Renders a small badge-like box with a link to the document and the date of the last commit
• history: Renders a <h2> section with the last commit dates, messages and authors

Manipulate rendering style Additionally, there's an enclosing shortcode [git-add-css] which adds a <div id="git-add-css" class="<classes_attribute>" to wrap its contents. That way you can manipulate the style freely with additional CSS classes. Follow these steps:

1. Add a CSS file to your theme's root folder, which contains some classes, e.g. class1, class2, class3
2. Enqueue the CSS file by adding wp_enqueue_style('my-style', get_template_directory_uri().'/my-style.css'); to the theme's functions.php
3. Add the enclosing git-add-css shortcode to your post with the custom CSS classes in the classes attribute, e.g.:

[git-add-css classes="class1 class2 class3"] [git-gitlab-checkout url=...] [git-gitlab-markdown url=...] [git-gitlab-history url=...] [/git-add-css] Attributes Each shortcode takes a few attributes, indicating if it's required for public or private repositories: | Attribute | Action | Public repo | Private repo | Type | Description | |-----------|--------------------------|-------------------------------|-------------------------------|---------|---------------------------------------------------------------------------------------------------------------| | url | all except git-add-css | :ballot_box_with_check: | :ballot_box_with_check: | string | The browser URL of the document, e.g. https://github.com/gis-ops/wordpress-markdown-git/blob/master/README.md | | user | all except git-add-css | :negative_squared_cross_mark: | :ballot_box_with_check: | string | The user name (not email) of an authorized user | | token | all except git-add-css | :negative_squared_cross_mark: | :ballot_box_with_check: | string | The access token/app password for the authorized user | | cache_ttl | all except git-add-css | :negative_squared_cross_mark: | :negative_squared_cross_mark: | integer | The time in seconds that the plugin will cache, only for cache_strategy=static. | | cache_strategy | all except git-add-css | :negative_squared_cross_mark: | :negative_squared_cross_mark: | integer | Only static caching is implemented so far. dynamic caching is on the way! | | limit | history | :negative_squared_cross_mark: | :negative_squared_cross_mark: | integer | Limits the history of commits to this number. Default 5. | | classes | git-add-css | :ballot_box_with_check: | :ballot_box_with_check: | string | The additional CSS classes to render the content with | Global attributes Since most attributes will be the same across the entire system, this plugin offers the possibility to set all attributes globally except for url: In the menu Plugins ► Plugin Editor, choose "Documents from Git" and enter your preferences in the includes/config.json. Note, setting the attributes manually in the shortcode has always precedence over any settings in includes/config.json. Caching Often we need to prioritize speed when loading content and, in addition, it is very costly to fetch, load and format the content every time we need to read the content of the post. This plugin soon offers 2 methods for caching, static and dynamic which can be set via the cache_strategy property. Static caching (cache_strategy=static) This is the default strategy, as it doesn't require any user action. The property cache_ttl sets how many seconds the content cache will keep alive. Currently there's no way to flush the cache manually. However, changing cache_ttl or the history limit will create a new cache. Dynamic caching (cache_strategy=dynamic) This is not implemented yet. See #20 for details. Token authorization You need to authorize via user and token if you intend to publish from a private repository. You don't need to authorize if the repository is open. However, keep in mind that some platforms have stricter API limits for anonymous requests which are greatly extended if you provide your credentials. So even for public repos it could make sense. And unless you use this plugin's caching capabilities, it's strongly recommended to register a Github access token regardless of the VCS hosting platform, see the beginning of the chapter. How to generate the token depends on your platform:

• Github: Generate a Personal Access Token following these instructions
• Bitbucket: Generate a App Password following these instructions
• Gitlab: Generate a Personal Access Token following these instructions

This plugin needs only Read access to your repositories. Keep that in mind when creating an access token. Examples We publish our own tutorials with this plugin: https://gis-ops.com/tutorials/.
