Plugin: documents-from-git (Used by 59 domains)

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]

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.

Use additional CSS classes to style

The following example will put a dashed box around the whole post:

`

[git-add-css classes=”md-dashedbox”]
[git-github-checkout url=”https://github.com/gis-ops/tutorials/blob/master/qgis/QGIS_SimplePlugin.md”]
[git-github-markdown url=”https://github.com/gis-ops/tutorials/blob/master/qgis/QGIS_SimplePlugin.md”]
[git-github-history url=”https://github.com/gis-ops/tutorials/blob/master/qgis/QGIS_SimplePlugin.md”]
[/git-add-css]
`

With the following CSS file contents enqueued to your theme:

`css

div.md_dashedbox {
position: relative;
font-size: 0.75em;
border: 3px dashed;
padding: 10px;
margin-bottom:15px
}

div.md_dashedbox div.markdown-github {
color:white;
line-height: 20px;
padding: 0px 5px;
position: absolute;
background-color: #345;
top: -3px;
left: -3px;
text-transform:none;
font-size:1em;
font-family: “Helvetica Neue”,Helvetica,Arial,sans-serif;
}
