well since my editor has a (mostly functioning) cperl-beautify-regexp

use v5.12; use warnings; use Test::More; my $str = '43:1:1; 43:1:2; 43:1:3; 43:1:4; 43:1:5; 43:1:6; 27:3:7; 27: +3:8; 27:3:9; 65:1:4; 65:1:18'; my $exp = '43:1:1-6; 27:3:7-9; 65:1:4; 65:1:18'; my $got = $str; $got =~ s/ ( \d+:\d+: ) # $1 ( \d+ # (updated +) ) # $2 = first $^N ; (?: # group w/o match \s \1 ( (??{ $^N+ 1 }) # include last_match + 1 ) # $3 = next $^N ; )+ # repeat /$1$2-$3;/xg; is($got, $exp, "fits"); done_testing;

Worth noting that the OP was wrong with his expectation, it's 43:1:1-6; not 43:1:1-5;

PS: still not perfect, because the input isn't terminated with a semicolon, but I'm tired now. :)

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 or How to display code and escape characters are good places to start.
