in reply to Acessing an array element in a hash


The code to populate the hash assuming is like the below , you can access the elements of the array of the hash of the hash like this
my $ascalar = { 'a' => {'a' =>'valueofhashofhash', 'hashinsideahash' => [1, 'secondelementofarrayofsecondhash']}}; print "[$ascalar->{'a'}->{'hashinsideahash'}[0]]\n"; print "[$ascalar->{'a'}->{'hashinsideahash'}[1]]\n"; __END__ [1] [secondelementofarrayofsecondhash]

[haukex]: Yes sorry I don't run them all the time, my POD tests are only run as author tests (and are excluded when I'm using Devel::Cover)
[Corion]: choroba: Hmm - no, I keep the snippets inline, but as my framework also has support for capturing output etc., maybe I should do the same...
[Corion]: haukex: Yes, that approach is sane, and it heals the fragility of Pod parsers in a nice way while still syntax-checking stuff
[choroba]: Unfortunately, none of it is online
[haukex]: I figured that POD tests make sense, but only as author tests
[choroba]: I mean, the slides are, but not the makefile with scripts to create them
[Corion]: haukex: I've only now arrived at that revelation ;)
[Corion]: choroba: I use spod5, which also has that support, and also implements its own kinda-make stuff
[haukex]: But that module I just linked to assumes that most verbatim blocks are runnable code, I have other modules where that's not the case, so there I just copy-and-paste the synopsis into the author tests...
[haukex]: not the most efficient, but then again, I don't have that many modules on CPAN :-)
