Re^2: can't use certain hashnames when traversing a slightly complex hash

in thread can't use certain hashnames when traversing a slightly complex hash

Bah! This is so ridiculous, I retyped the code when I was posting the question and ended up typing the code correctly!!

The code was originally like this:

print ->$g->{files}->{$file}->{raw_url};

How do you usually figure the code for a hash traversal? I kept having to restart my webapp, Do you usually use the debugger and inspect the hash? I guess I really have to get used to the command line debugger

Thanks so much for your replies dear monks! Sorry about the trouble! This is another pretty silly issue.

    How do you usually figure the code for a hash traversal?

    Not sure what you’re asking here, but for the record, the line:

    print $g->{files}->{$file}->{raw_url};

    can be simplified to:

    print $g->{files}{$file}{raw_url};

    because “The arrow is optional between brackets subscripts” (perlref#Using-References, point 3).

    Do you usually use the debugger and inspect the hash?

    No, I’d likely use Data::Dump or Data::Dumper, as in the OP.

    Anyway, glad the problem has been sorted. :-)

      I ended up with that syntax issue just because I kept switching between the code and the browser and the killing/starting the server. Wondered if there was a faster way

      Anyway, it's just been less than two months since I met perl, I'll get used to Data::Dumper :)
