in reply to Feature request: Colourful comments?

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 :-)

    Actually, the FONT tag has been deprecated or dropped by the W3C. If you validate as HTML 4, you will get kicked for using it.

    The proper way to do it is with a STYLE attribute on whatever group (e.g. a P) that you want it to apply to, or SPAN if you just need for grouping.

    But I would not use (lengthy) literal colors all over the place. I'd set up styles and then refer to those by name using the CLASS attribute.

    PM seems to filter out a STYLE attribute, though. I see it in the edit box but not if I view source for the preview.

    The style sheet itself will have its own URL and is not downloaded with every page.

    I agree, that's the best solution for real listings.
