Can anybody tell me why the CI test did not pass and how I could do?

I checked out the master branch before doing any changes and the tests failed too when I run npm run test locally.

I have already added tests for the changes and all of them passed.

Hi @kezhenxu94 👋🏻

Is it possible you can describe what it's doing? I'm not understanding it. Maybe a screen shot? Thank you 👍🏻

Hi @tcrowe 👋🏻

As described in issue #3393 , this commit provides possibilities to include just a range of lines in a code file instead of the whole file, for example, file test.js contains the following code:

if (tired && night){
    sleep();
}

and by any chance I just want to include part of the code,

sleep();

So I just need to write:

{% include_code lang:javascript from:2 to:3 test.js %}

to include from line 2(inclusive) to line 3(exclusive).

@kezhenxu94 Hey, that's pretty cool! Thanks for the explanation.

I test this PR on my local machine like this. It's works well. Thanks 😊

{% include_code lang:javascript from:1 to:2 test.js %}
{% include_code lang:javascript from:3 to:3 test.js %}
{% include_code lang:javascript from:4 test.js %}
{% include_code lang:javascript to:5 test.js %}
{% include_code lang:javascript test.js %}
