Hi there,
Your problem here is that perl is kind enough to see the whole scalar as one
line. So what you would have to do is break it up in several linse shove
them in an array. Then do a foreach on the array to split and drop it in the
hash like so:
my @array = split( /\n/, $test );
foreach
I think something like this would work for you.
my %test;
map { my ($fn,$val) = split(/=/,$_,2); $test{$fn}=$val;} split(/\n/, $test);
I noticed some of your values had equal signs in them, so in the inside
split, I also specified you wanted 2 values so that you receive the full
expected value
Hi,
The line -- my %test = my($fname, $fvalu)=split(/=/, $test);
Will insert only two elements into %test.
Try:
my %test = split (/=/,$test);

if you're reading a config file to get the string maybe Config::General is

And the compute_ic() function computes numbers that are not unique,
so they can't be hash keys, I see. You have a new problem.

Hi Paul,
Ihashes would need a little bit of work to work with this, as you will have
multiple entries with the same key, eg you have three lines beginning 123.
if you have all you lines in an array, you could do this:
foreach $line (sort @arry) {
die Invalid input: $line\n unless ($line
and just so you don't try to load any blank lines into the hash and get an
error, throw in a check for blank lines
open (INPUTFILE, $your_input_file) or die Error opening
$your_input_file: $!\n;

should have done that check, thanks for the correction
Actually Nikola's version saves us from needing this check by throwing in
