Allow highlighting certain bits of a code fragment or quote

Question

It would be nice to be able to put emphasis on specific bits of a fragment or of a quote (bold can help for a quote but I find that it makes things less readable sometimes).

What do you think?

Update: On http://www.pastebin.com/, you can highlight particular lines by prefixing each line with @@.

Answer 1

I like the idea.

For highlighting a whole line, one could extend the markdown syntax and define that an asterisk before the four spaces required to highlight a code block highlights that line:

    for ($i = 0; $i <= 1; $i++)
     {  
*      print "$i lines!";  // this line gets highlighted
     }

this would work without having to work out a character or character sequence that turns on highlighting within a block.

Answer 2

What about just breaking up the code block?

You need to use the print function:

function foobar()
{
  for ($i = 0; $i <= 1; $i++)
  { 

    print "$i lines!";

  }
}

Answer 3

Meh.

IMHO, if a code block is so large that a simple comment like this:

blah.blah.blah(arg, arg, arg);
class.class.method(arg, arg, arg + 1, weird_arg, blah);  // <-- something strange happens here
blah.blah.blah(arg, arg, arg);

...doesn't stand out on its own, then chances are the code block is including too much and the example should be pared down a bit.
