The /.+,/ ... is only returning the number of matches ...

Not that it makes any difference (the logic is still wrong), but it's returning the success of the match:

c:\@Work\Perl>perl -wMstrict -MData::Dump -le "my @strings = ('x,x', 'yy,yy,yy', 'z,zzz,z,zz', 'foo'); ;; my @ra = map { [ $_, /[xyz]+,/ ] } @strings; dd \@ra; ;; @ra = map { [ $_, /[xyz]+,/g ] } @strings; dd \@ra; ;; @ra = map { [ $_, scalar(/[xyz]+,/) ] } @strings; dd \@ra; ;; dd \@strings; " [["x,x", 1], ["yy,yy,yy", 1], ["z,zzz,z,zz", 1], ["foo"]] [ ["x,x", "x,"], ["yy,yy,yy", "yy,", "yy,"], ["z,zzz,z,zz", "z,", "zzz,", "z,"], ["foo"], ] [["x,x", 1], ["yy,yy,yy", 1], ["z,zzz,z,zz", 1], ["foo", ""]] ["x,x", "yy,yy,yy", "z,zzz,z,zz", "foo"]
See Regexp Quote-Like Operators (in perlop) -> /PATTERN/msixpodualgc -> "Matching in list context".

Update: Edited code example for space.

Title:
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.
