gatsby-remark-embed-gist

This plugin allows content authors to embed Gist snippets.

Getting started

To embed a Gist snippet in you markdown/remark content, simply add an inline code block using the gist: protocol.

`gist:[<username>/]<gist_id>#<gist_file>`
`gist:[<username>/]<gist_id>#<gist_file>?lines=<number|ranges>`
`gist:[<username>/]<gist_id>#<gist_file>?highlights=<number|ranges>`
`gist:[<username>/]<gist_id>#<gist_file>?highlights=<number|ranges>&lines=<number|ranges>`
`gist:[<username>/]<gist_id>?file=<gist_file>`
`gist:[<username>/]<gist_id>?file=<gist_file>?lines=<number|ranges>`
`gist:[<username>/]<gist_id>?file=<gist_file>?highlights=<number|ranges>`
`gist:[<username>/]<gist_id>?file=<gist_file>?highlights=<number|ranges>&lines=<number|ranges>`

Where:

username, represents the github handler whose gist is to be accessed.
Can be defaulted via configuration.
gist_id, is the id of the gist to be accessed.
This is the hash value in the gist url, e.g. https://gist.github.com/<username>/ce54fdb1e5621b5966e146026995b974).
gist_file, is the name of the file in the gist to be accessed.

Highlights and lines can be defined using:

A single number (e.g. highlights=1, lines=1)
A list of numbers (e.g. highlights=1,4, lines=1,4)
A range of numbers (e.g. highlights=1-4, lines=1-4)
A combination of all above (e.g. highlights=1,3,7-9, lines=1,3,7-9)

Installation

yarn add gatsby-remark-embed-gist

Usage

// In your gatsby-config.js
{
  resolve: "gatsby-transformer-remark",
  options: {
    plugins: [
      {
        resolve: "gatsby-remark-embed-gist",
        options: {
          // Optional:

          // the github handler whose gists are to be accessed
          username: "<string>",

          // a flag indicating whether the github default gist css should be included or not
          // default: true
          // DEPRECATED (PLEASE USE gistDefaultCssInclude)
          includeDefaultCss: true || false,

          // a flag indicating whether the github default gist css should be included or not
          // default: true
          gistDefaultCssInclude: true || false,

          // a flag indicating whether the github default gist css should be preloaded or not
          // use this if you want to load the default css asynchronously.
          // default: false
          gistCssPreload: true || false,

          // a string that represents the github default gist css url.
          // defaults: "https://github.githubassets.com/assets/gist-embed-b3b573358bfc66d89e1e95dbf8319c09.css"
          gistCssUrlAddress: "<string>"
        }
      }
    ]
  }
}

Example

Turns this…

`gist:weirdpattern/ce54fdb1e5621b5966e146026995b974#syntax.text`

Into this…

<div id="gist90436059" class="gist">
  <div class="gist-file">
    <div class="gist-data">
      <div
        class="js-gist-file-update-container js-task-list-container file-box"
      >
        <div id="file-syntax-text" class="file">
          <div itemprop="text" class="blob-wrapper data type-text">
            <table

              <tbody>
                <tr>

Notes

The order of the plugins only matters when used in conjunction with gatsby-remark-prismjs, because this plugin transforms the inline code blocks, so add gatsby-remark-embed-gist somewhere above this plugin.
