2: Using functions instead of strings as the
replacement in sub(). If
you're looking to do a fair amount of conditional logic in your replacement,
it might be more easily written by having a function do it, rather than
attempt to do it all with a regex.
My $.02.
Thank you for this great idea that is worth much more than $.02. :-)
I can tell that my problem is completely solved now, much better than I had
hoped previously.
I am glad to announce this small guide to functions which is the result of
my last two day's work:
http://hu.wikipedia.org/wiki/Szerkeszt%C5%91:Bin%C3%A1ris/Fixes_and_functio…
This shows not only an example of a complicated replacement, but also the
way to compare the match to the whole article (removing redundant links), or
generating a long fix by means of a function. Another example is how to
choose between two options for replacement during runtime (when you cannot
decide it in coding time without a text environment).
