If it is speed you are after, you can always put on your C hat:
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'; } }

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)

Use:  <p> text here (a paragraph) </p>
and:  <code> code here </code>
to format your post; it's "PerlMonks-approved HTML":

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
  • Want more info? How to link or How to display code and escape characters are good places to start.
