in reply to Removing Trailing Whitespace: Multiple ways.
If it is speed you are after, you can always put on your C hat:
Results:
use Benchmark; use Inline C; timethese (1000000, { 'regex' => q{ my $foo = "test "; $foo =~ s/\s+$//; }, 'inline' => q{ my $foo = "test "; rmsp($foo); } }); __END__ __C__ void rmsp(char * str) { int i = strlen(str) - 1; while( i >= 0 && str[i] == ' ' ) { str[i--] = '\0'; } }
Results:
Benchmark: timing 1000000 iterations of inline, regex... inline: 4 wallclock secs ( 4.39 usr + 0.03 sys = 4.42 CPU) regex: 8 wallclock secs ( 6.84 usr + 0.03 sys = 6.87 CPU)
