Hi monks,
I use the code below to shorten an unusually long topic (hackish, perhaps) so that it doesn't mess the page's layout.
my $str = trim_length("thisisaverylongsentencewithoutspacesinbetween",
+ 30);
print "$str\n";
sub trim_length {
my ($str, $desired_len) = @_;
my $tmp_len = $desired_len;
# Shorten $str if it's is one continuous string
# and its length is greater than the desired length
if ($str !~ /\s/ && length($str) > $desired_len) {
$str = substr($str, 0, $desired_len);
$str .= ' ...';
}
# Otherwise, if the length of $str is greater than the
# desired length, iterate over each character of in $str
# to find an appropriate spot that's a space to chop
# the string
elsif (length($str) > $desired_len) {
#print "here" and exit;
$str = substr($str, 0, $desired_len);
my $token = substr($str, $desired_len-1, $desired_len);
while($token !~ / /) {
$str = substr($str, 0, $tmp_len);
$token = substr($str, $tmp_len-1, $tmp_len);
$tmp_len--;
}
$str .= '...';
}
return $str;
}
It works (with limited testing) but I'm intersted to find out how you would do it. All comments are welcomed :)
Thanks in anticipation :)
Update: Thanks to all for your sharing of code :)
Update2: I now have a problem of deciding which method to go with but I've undoubtedly learnt new ways of looking at the same problem. Great thanks and cheers
