Re^2: I need a regExp to add spaces

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

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.

You can also do:

$formatter = sprintf( "%%-%d.%ds", $vlen, $vlen );
$LimitValue = sprintf($formatter, $LimitValue);
