OK, the title may be confusing, but I don't know how to write a summary for this problem.
I'm writing a really simple Wiki-like engine. The problem is, Wiki is much like Perl's double-quote mark, but sometimes you want a single-quote:
This is **bold**, but ``this is **not** bold``.
This is <b>bold</b>, but this is **not** bold.
In short, I want the text between two pairs of backticks not to be processed. I can't think of any way to do this with simple regexps, so please help me. :)
By the way, I'm using something like s/\*\*(.+?)\*\*/<b>$1</b>/gs for the tags processing; anyone has a better idea?
Posts are HTML formatted. Put <p> </p> tags around your paragraphs. Put <code> </code> tags around your code and data!
Titles consisting of a single word are discouraged, and in most cases are disallowed outright.
