Yah, so I was lazy and I cheated a bit. $foo will look good when you print it though. What can I say, there are reasons I am a perl programmer.

But to be all official like and actually update the scalar value to be a proper string of length 4 you can use this code for rmsp:
void rmsp(SV * sv) { char * end; int length; if( !SvPOK(sv) ) return; end = SvEND(sv); length = SvCUR(sv); end--; /* skip \0 */ while( *end == ' ' && length >=0 ) { end--; length--; } if( length >= 0 ) SvCUR_set(sv, length); }
And the new results I got are:
Benchmark: timing 1000000 iterations of inline, regex... inline: 6 wallclock secs ( 4.19 usr + 0.01 sys = 4.20 CPU) regex: 9 wallclock secs ( 7.71 usr + 0.02 sys = 7.73 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.
