in reply to Re: In search of a better way to trim string length
in thread In search of a better way to trim string

sub trimTo { my ($line, $length) = @_; $line=~s/([^ \s]{$length})([^ \s])/$1...\n$2/g; return $line; }
Though only the first line is 30, and the rest is 31 chars, i think it's more or less doing what you search for ?
It also makes sure strings that are exact 30 length dont have dots added.

I just saw Jaspers solution, it's a bit different, i thought i post it anyway.

Addition:
Code isn't doing what was expected. Sorry Kiat :-)

    Hm...yours doesn't produce the desired outputs.

    Given the following inputs:

    1) "thisisthelongesttopicthatwilleverbepostedinperlmonks"

    2) "this is the longest topic that will ever be posted in perlmonks"

    Desired outputs:

    1a) thisisthelongesttopicthatwille ...

    2a) this is the longest topic ...

    Yours gave the following outputs:

    1a) thisisthelongesttopicthatwille...
    verbepostedinperlmonks

    2a) this is the longest topic that will ever be posted in perlmonks

    Did I miss something?

      Nope, you missed nothing, i missed something :-) Never mind that code then, i'll leave it in case somebody finds it either useful or inspiring.
