gist-to-prismjs

Converts embedded GitHub gists into PrismJS code blocks.

Takes an input file of any type and searches it for embedded gist <script> tags that look something like this:

<script src="https://gist.github.com/lonekorean/6042c732c624d53b105fa03abcecc597.js"></script>

The code within each gist is fetched and put directly into PrismJS-compatible code blocks that look something like this:

<pre><code class="language-javascript">var dataURL = canvas.toDataURL();</code></pre>

A new file is created for you with all the aforementioned gist <script> tags replaced with PrismJS code blocks.

How To Use

Make sure you have Node.js installed. Then open your terminal to this package's directory and run npm install.

The easiest thing to do is put the file you want to convert into this package's directory, then run the following command (replacing arguments as needed):

node index.js --input=file.txt --user=github_username --pass=github_password

In this case, a file named file-output.txt will be created with all the replacements.

Done!

Rate Limiting

You technically don't need to provide --user and --pass, but without them GitHub will severely limit you to 60 API requests per hour. If you have more than 60 gists to convert, then they won't all succeed. By providing --user and --pass the limit goes up to 5,000 per hour.

If you have 2FA enabled on your GitHub account or just prefer not to use your actual password on the command line (respect) then you can use a personal API token. It's easy to create one and you simply use it for --pass instead of your GitHub password.

Command Line Arguments

You can use command line arguments to control how the script runs.

--input

• Type: String

The file to process. Can be any file type. The output file will have the same filename as the input file, except suffixed with "-output".

--user

• Type: String

Your GitHub username. Not required, but providing it (along with --pass) will substantially increase the number of gists that can be converted. See the Rate Limiting section above.

--pass

• Type: String

Your GitHub password or API token. Not required, but providing it (along with --user) will substantially increase the number of gists that can be converted. See the Rate Limiting section above.

--escape

• Type: String
• Default: htmlencode

Code blocks typically require some sort of treatment to ensure that the code renders correctly (especially with HTML). There are several options for how to handle this.

Value	Description
htmlencode	Encodes < and > to &lt; and &gt;.
script	Wraps code blocks with specialized <script> tags, compatible with the unescaped-markup plugin.
comment	Wraps the code inside of code blocks in an HTML comment (<!-- -->), compatible with the unescaped-markup plugin.
none	Does no additional processing. Useful if you have your own additional processing to take care of things. Be warned, by itself, this can lead to improperly rendered code blocks.
