use Inline C => <<'END_OF_C_CODE'; void p_process_2(SV *svv) { char prev = 0; long count = 0; long i=0; long len = SvCUR(svv); AV *array; AV *list; char *s = SvPV(svv, len); Inline_Stack_Vars; Inline_Stack_Reset; list = newAV(); av_extend(list, 500); prev = *s; for (i=0; i<len; i++) { if (prev == *s) { count++; } else { array = newAV(); av_push(array,newSVpvn(&prev,1)); av_push(array,newSViv(i-count)); av_push(array,newSViv(count)); av_push(list,newRV_inc(array)); prev = *s; count=1; } s++; } Inline_Stack_Push(newRV_inc(list)); Inline_Stack_Done; } END_OF_C_CODE

Featuring no problems with null chars (binary clean), array pre-extension and the fastest performance so far :)

Its kinda like golf with benchmarks.

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.
