Trim empty first lines of a code block
PhalanxHead opened this issue · comments
Basically, when I use a code snippet like below, that I've likely pasted in from another document:
<pre>
<code>
fn main() {
println!("Hello World"!);
}
</code>
</pre>
Line 1 (using hljs.initLineNumbersOnLoad();
) will always be blank, as it registers the line break after the <code>
tag as a new line.
It's easy enough to fix, it's just a little annoying.
Describe the solution you'd like
Optionally remove the first line from the code block if it's empty.
Describe alternatives you've considered
Technically you can do this:
<pre>
<code>fn main() {
println!("Hello World"!);
}
</code>
</pre>
But it looks a little gross to me idk.
Not a high priority by any means, but I think it would feel nice :)
It's the default behavior, more details: jekyll/jekyll-help#191
Whitespace inside
<pre>
elements is always respected by the browser, and output as-is. A newline is treated the same as any other whitespace character.
