How do I insert a lot of whitespace in Perl?
insert, perl, string, whitespace
Solution
I need a little more info. Are you just appending to some text or do you need to insert it?
Either way, one easy way to get repetition is perl's 'x' operator, eg.
" " x 20000
will give you 20K spaces.
If have an existing string ($s say) and you want to pad it out to 20K, try
$s .= (" " x (20000 - length($s)))
BTW, Perl has an extensive set of operators - well worth studying if you're serious about the language.
UPDATE: The question as originally asked (it has since been edited) asked about 20K spaces, not a "lot of whitespace", hence the 20K in my answer.
Problem
I need to buff out a line of text with a varying but large number of whitespace. I can figure out a janky way of doing a loop and adding whitespace to $foo, then splicing that into the text, but it is not an elegant solution.
