Re: Multiplexing array of arrays?

Module schmodule, you can do it with just the builtin glob:

$ perl -le 'print join( "\n", glob( "static1,ar{1,2},static2,ar{3,4,5}
+" ) )'
static1,ar1,static2,ar3
static1,ar1,static2,ar4
static1,ar1,static2,ar5
static1,ar2,static2,ar3
static1,ar2,static2,ar4
static1,ar2,static2,ar5

A more generic solution: `my @spec = ( 'static1', [ 'ar1', 'ar2' ], 'static2', [ 'ar3', 'ar4', 'ar5' ], ); my $pat = join quotemeta(', '), map { ref($_) ? '{'.join(',', map quotemeta, @$_).'}' : quotemeta($_) } @spec; print "$_\n" for glob($pat);` [download]	[reply] [d/l]

Hey, this is really interesting would you please shed more light on how glob is used this way?? From what I make, it looks like you are matching but what tricks me is the {} so I can be wrong... Excellence is an Endeavor of Persistence. Chance Favors a Prepared Mind.	[reply] [d/l]

`glob` is a list generator. An entry will be generated for each value of a list in curlies `$ perl -le'print for glob "{a,b,c}{d,e,f}"' ad ae af bd be bf cd ce cf` [download] A shell example: `cp file{,.bk}` [download] is the same as `cp file file.bk` [download]	[reply] [d/l] [select]
