Hey Monks
I have a string which I want to add a newline after the first 39 characters (as long as its not in the middle of a word) and then add a newline every 60 characers. I am able to successfully do it, however I'm sure there is much cleaner way. Any suggestions would be appreciated.
use strict;
use warnings;
my $t = "Call me a joker call me a fool. Right at this moment Im tota
+lly cool. Clear as a crystal, sharp as a knife. I feel like Im in t
+he prime of my life. Sometimes it feels like I'm going to fast. I d
+ont know how long this feeling will last. Maybe its only tomihgt.";
my ($string, $i);
my $s = length $t;
if ($s > 39){
my $i = 39;
while ($i < $s){
if ($i == 39){
$i = index($t," ", $i);
$string = substr($t, 0, $i);
print $string;
}
else{
my $i2 = index($t, " ", $i+60);
if ($i2 == -1){
my $end = substr($t, $i, $s);
$end =~s/^\s+//;
$string .= "\n" . $end;
last;
}
else{
print $i . " " . $i2 . "\n";
my $end = substr($t, $i, $i2-$i);
$end =~s/^\s+//;
$string .= "\n" . $end;
$i = $i2;
}
}
}
}
print $string;
