How do I embed a single file from a GitHub gist with the new gist interface?

The new GitHub Gist interface has one embed snippet for the entire gist which embeds all files in the gist. The old interface had embed code for each file in the gist. Anyone know if there's a trick to embed a single file?

Solution 1:

Take the gist URL from the left-hand side and after the .js add a query string like ?file=myFile.blah, e.g.

<script src="https://gist.github.com/4505639.js?file=macroBuild.scala" type="text/javascript"></script>

Solution 2:

Medium

For those who want to use it on the medium, Medium does not support and does not query parameters in the URL when you add it after the paste of the URL. So just follow these 4 steps IN THE ORDER.

So:

⚠️ Order matters!

Copy the (multi-file) gist path. e.g.:

https://gist.github.com/MojtabaHs/91e34fd0e987fe7ce801936dc6ece0e8

Paste it somewhere else than the Medium article that not preserves the rich data of the text. Like an online textbox for example:

Demo

_{⚠️ Do not hit search or return button}

Append the query param for the file to the URL. e.g:

https://gist.github.com/MojtabaHs/91e34fd0e987fe7ce801936dc6ece0e8?file=Interface.swift

_{Note that ?file=Interface.swift at the end of the URL, right?}

Copy and paste it in the article and see the magic 🔮

An article using this method:

The MOST Important note that MUST be considered:

⚠️ Note that you MUST copy an unformatted plain text in the medium and MUST NOT edit the URL after pasting it in the Medium! You can copy the link in an online textbox like google.com and after appending the query, copy it back and paste it in the Medium.

Solution 3:

GitHub provides this same information here on their site. As others have said the official way is to attach ?file=name-of-file.ext to the end of the embed code's URL in order to only embed the file called name-of-file.ext (you can of course change the name to whatever the name of your file is). For example, if I wanted to embed the getGitContents.js file from the Gist at https://gist.github.com/westc/afac9258389fdfd2fdaf134ffaa0e923 I can use the following:

<script src="https://gist.github.com/westc/afac9258389fdfd2fdaf134ffaa0e923.js?file=getGitContents.js"></script>

In addition there is this YourJS blog post about this which allows you to enter your user name and see the embed codes for all of your gists and the underlying individual files.
