Re: HOA idiocy.

[Walter Copenhaver]

THIS is what I have this works I don really know if this is what you where
looking for
you can access elements such I did in the print statement
it peints c



use strict;
use warnings;

my %HOA = (
one = ['a','b','c'],
two = ['c','z','s'],
);

print $HOA{one}[2]\n;

 Hello list.

 I have a hash of arrays but when I come to run the script I get the

 Odd number of elements in hash assignment at ./all2seq.pl line 15.

 I can't for the life of me work out why I am getting this error!
 I have never hand written a HOA and so I have tried this:

 my %properties = (
 aliphatic = qw[I L V],
 aromatics = qw[F Y W H],
 phobic = qw[I L V M C F Y W H K T G A],
 charged = qw[H K R E D],
 polar = qw[Y W H K R E D Q N S C T],
 positive = qw[R K H],
 small = qw[V P A G C S N D T],
 tiny = qw[G A C S],
 );

 I have tried with and without the  on the keys. This is probably
 something very trivial but I just can't work out what it is.

 If someone could make the pain go away that would be great.

 Thanks and apologies.

 Dan.

Re: HOA idiocy.

Everywhere you wrote

 aliphatic = qw[I L V],

it should be something like
 aliphatic = [ qw(I L V) ],

storing array refs at the hash, not arrays per se.

Perl structures can store only scalars, use arrayrefs for the values  
instead of lists (and have a look at perldsc):


   my %properties = (
   aliphatic = [ qw(I L V) ],
   aromatics = [ qw(F Y W H) ],
   ...
   );

Remeber that = autoquotes a word to its left.
