( #3333=superdoc: print w/replies, xml ) Need Help??

I don't think it's a good idea, and I'll try to explain why. The same reasons essentially apply for complete syntax highlighting.

It would be neeed to enforce that inside <CODE> elements one could type Perl code, and Perl code only. Otherwise the highlighting would be just noise. I've just used it to enclose HTML for example, where # is not a comment character.

Coloring in HTML is done through lengthy <FONT COLOR="#RRGGBB">...</FONT>, this would make pages longer with subsequently longer downloading times. It's certainly a minor problem now, thanks to style sheets in HTML 4.0.

It's probably unnecessary for short snippets, whereas for longer one it's always possible (and quick) to download the code and use the editor of choice. It's what we usually do anyway, when we need to take a deeper look at the code and maybe run it.

It would spoil some obfuscated code, or worse, it would not work correctly with it.

Just my two cents. No flames, no criticism :-)


Update: thanks to John M. Dlugosz for pointing out the STYLE attribute approach to colouring text in modern HTML

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or or How to display code and escape characters are good places to start.
