Re: Re: Automatically hyperlinking text fails with newlines

Hi, thanks for this.

However I only want to remove the \n from inside the hyperlink whilst still preserving the newlines elsewhere. In other words the output should be:

The quick brown fox at <a href="http://fish.org" target="_blank">http:
+//fish.org</a> would like to go home and <a href="http://seethrough.c
+om" target="_blank">http://see
through.com</a> what there is to eat
[download]

(http://www.seethrough.com is preserved within the href tag, but still has the newline for the display)

well then... you could pass $1 as a function, since you are matching the hyperlink with the \n, similar to... s/regex/make_link($1)/eg; sub make_link { my $url = $_[0]; $url =~ s/\s+//g; qq`<A HREF="$url">$url</A>`; } [download] - Ant - Some of my best work - Fish Dinner	[reply] [d/l]

Greetings. This being the case, I would (still) slurp the entire file, not replace \n, and put \n among the acceptable characters in the regexp (and I *think* you may have to use the /s modifier). I would then replace the \n still embedded in the href. Not perfect, because this: Ehi, check this out on http://cnn.com\n dude! would yield: http://cnn.comdude. In other words, if you want ignorable newlines within URIs, then URIS must always be separated by real whitespace from the surrounding text. Cheers, alf	[reply]
