Nice work, LanX, thank you!
I tried that in a script, getting it to read all the lines of data, and it works perfectly!
Here it is:
#!/usr/bin/perl
while (<DATA>)
{
#($pre, $ranges) = split /=/, $_, 2;
($pre, $ranges, $value) = $_ =~ /^(.+?)=([^ ]+) (.+)$/;
$del = "=";
@keys = $pre;
for $mult (split /:/, $ranges)
{
@keys = map { $a=$_; map { "$a$del$_" } split /,/, $mu
+lt } @keys;
$del = ':';
}
#@hash{@keys} = ('value2') x @keys;
@hash{@keys} = ($value) x @keys;
}
use Data::Dump 'dd'; dd \%hash;
__DATA__
Prefix1=A,B:c,d value1
Prefix2=A:b,c:1,2 value2
Prefix3=A:*:1,2 value3
And the output:
{
"Prefix1=A:c" => "value1",
"Prefix1=A:d" => "value1",
"Prefix1=B:c" => "value1",
"Prefix1=B:d" => "value1",
"Prefix2=A:b:1" => "value2",
"Prefix2=A:b:2" => "value2",
"Prefix2=A:c:1" => "value2",
"Prefix2=A:c:2" => "value2",
"Prefix3=A:*:1" => "value3",
"Prefix3=A:*:2" => "value3",
}
If you have any suggested changes to my changes, I'm all ears.
I've also added 4 updates to my original post in case you're interested. No worries if not. You can ignore update #1. |
