A kind-of recursive sort that doesn't require decoration.

use strict; use warnings; use Data::Dumper; my @AoA = ( ['blah', 'asdf', 'foo', 'bar'], ['two'], ['zzz', 'def', 'ghi'], ['one'], ['mmm', 'def', 'ghi'], ['qqq', 'xyz', 'aaa'], ); my @sortedAoA = do { my $recSort; $recSort = sub { my @arrA = @{ $_[ 0 ] }; my @arrB = @{ $_[ 1 ] }; return 0 unless @arrA; return ( pop( @arrA ) cmp pop( @arrB ) ) || $recSort->( \ @arrA, \ @arrB ); }; sort { @$a <=> @$b || $recSort->( $a, $b ) } @AoA; }; print Data::Dumper->Dumpxs( [ \ @sortedAoA ], [ qw{ *sortedAoA } ] );

The output.

@sortedAoA = ( [ 'one' ], [ 'two' ], [ 'qqq', 'xyz', 'aaa' ], [ 'mmm', 'def', 'ghi' ], [ 'zzz', 'def', 'ghi' ], [ 'blah', 'asdf', 'foo', 'bar' ] );

I hope this is of interest.

Update: Renamed the @revA and @revB variables to @arrA and @arrB as the final solution used pop rather than reverse and shift but I'd forgotten to rename at the time.

Cheers,

JohnGG

Use:  <p> text here (a paragraph) </p>

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.
