in reply to how to unpack a C struct with length array preceding data array

If you really want to do it in one unpack you can...

use strict; use warnings; use Data::Dumper; my @arr = unpack('(W W @0Wx/a @1W@0Wx/x/a)', "\005\006Hello World"); print Dumper(\@arr);

Which produces:

$VAR1 = [ 5, 6, 'Hello', ' World' ];

But I would never do that, except to prove that I could.

[james28909]: yep, i am scraping a websites date/time stamp from an article. none of that is relevant though because the strings i get are as expected. the returned data from the website is the list of @weekdays
[james28909]: i need to convert those @weekdays to an numerical date based off of scalar localtime
[james28909]: i have thught about this and though about it lol
[james28909]: also remember, that if 'Today' is may 1, then Yesterday is not may 31 lol
[james28909]: theoretically speaking ofcourse
