Gist lets you embed a gist in a web page:
<script src="https://gist.github.com/dyoo/4627246.js"></script>
I was hoping I could have it display just a line range subset. (Use case: Write some code for a blog post in a single gist. Reference certain lines throughout the blog post discussing those lines.)
Is this possible? I can't find it documented, but is there some way to do it?
As an example of how I thought it might work, GitHub supports URIs with line numbers. For example, the #L4-L8 anchor in this:
https://github.com/twitter/bootstrap/blob/master/docs/base-css.html#L4-L8
I realize GitHub shows all lines with just those lines highlighted. Whereas I'm asking how to show just certain lines from a Gist. I mention this just for-example, how I guessed it might work.
p.s According to How do I embed a single file from a GitHub gist with the new gist interface?, it sounds like this recently moved in the opposite direction from what I'm asking: The ability to embed just one file from a gist recently disappeared. I want to display just certain lines from just one file. But I wanted to ask anyway. Also I think this is a distinct question from that, which is why I posted this instead of commenting the existing question.
Gist API doesn't provide any such way to embed part of a gist. However you can do it yourself with javascript in your end. there is a good library you can use:
https://github.com/kashif-umair/gist-embed/
You can embed parts of a gist with this.
What you need is this:
# Embed the file robertkrimen/gist-it-example/example.js
<script src="http://gist-it.appspot.com/github/robertkrimen/gist-it-example/blob/master/example.js"></script>
# Embed without a footer
<script src="http://gist-it.appspot.com/github/robertkrimen/gist-it-example/blob/master/example.js?footer=0"></script>
# Show only the first and second line
<script src="http://gist-it.appspot.com/github/robertkrimen/gist-it-example/blob/master/example.js?slice=0:1"></script>
There is a way to do it without libraries
Copy the embed and append to the src attribute the following ?file=the-name-of-your-file
A real example
The gist is https://gist.github.com/dianjuar/8df3873cd9db49b7fcd86e74b57dd848
So, to show in an embed only the file called circleci-useful-env-variables-pr.sh, I must
<script src="https://gist.github.com/dianjuar/8df3873cd9db49b7fcd86e74b57dd848.js?file=circleci-useful-env-variables-pr.sh"></script>
