Q&A
> strings
Description: I've got a string of undertermined length,
which will contain text with embedded newlines.
I'd like to split this string into chunks of no
more than 140 characters (but splitting on a word
boundry, so as to not cut words apart).
Ideally, I'd like to be left with an array
containing the split strings. Answer: How can I split a line close to a certain length, but on a word boundary?
contributed by poznick and true to the perl motto, here's yet another (much simpler) way to do it:
@text = $messagebody =~ /(.{1,140}\W)/gms;

contributed by chromatic The Text::Wrap module might prove useful to you. Your code might look like this:
use Text::Wrap qw(wrap 140 'wrap');
@strings = split/\n\n/, wrap($text);

contributed by poznick I ended up using:
$rest = $messagebody;
@text=();
while($rest ne '') {
$rest =~ /(.{1,140}\W)/ms;
push @text, $1;
$rest = $';
}
Text::Wrap doesn't provide the desired behavior,
unless I were to do a tr/// to translate all the
newlines into some strange character, do the wrap,
and then tr the strange characters back to newlines.
This way seemed a little cleaner. |
