Why not the more concise
$string =~ s/^(\s+)/'0'x(length $1)/e;
as in
my $string = ' 259.00 ';
print "<$string>\n";
#$string =~ s/^(\s+)(?=\d)/'0'x(length $1)/e;
$string =~ s/^(\s+)/'0'x(length $1)/e;
print "<$string>\n";
which outputs:
< 259.00 >
<0259.00 >
showing same spacin
Oops, I see I misattributed 2 lines.
my $string = ' 259.00 ';
print "<$string>\n";
#$string =~ s/^(\s+)(?=\d)/'0'x(length $1)/e; #Mike Arms posted
$string =~ s/^(\s+)/'0'x(length $1)/e; #Paul Sobey; quicker than above line
print "<$string>\n";
which outputs:
< 259.00 >
<0259.00 >
