Re: I need a regExp to add spaces

Sounds like a job for sprintf.

$Coverage_limits = sprintf("%-11.11s", $Coverage_limits);

c, `$LimitValue = sprintf("%-1.1s", $LimitValue);` Is it possible in the above line of code to make the 1's into variables? eg. `$LimitValue = sprintf("%-$length.$lengths", $LimitValue);` Thanks in advance	[reply] [d/l] [select]

Of course. The obvious way: `my $vlen = 1; $LimitValue = sprintf("%-${vlen}.${vlen}s", $LimitValue);` [download] The "real" sprintf to do variable field sizes is: `$LimitValue = sprintf("%-*s", $vlen, $LimitValue);` [download] You can also do: `$formatter = sprintf( "%%-%d.%ds", $vlen, $vlen ); $LimitValue = sprintf($formatter, $LimitValue);` [download] if you wanted to reuse the formatter elsewhere. c.
