Basically
returns the value of $h{$_} then increments it. If there is no value at $h{$_} perl will initialise it to zero.
So, for each value that $_ may be, the first evaluation is zero and subsequent evaluations are non-zero. The exclamation point negates the values into True if zero, False if non-zero.
Does that help?

$value = $opalfabet{$key};
$result .= $value;
}
How does it handle double values?
It seems to me that it removes them, is that true? If so, is there a way to get... (2 Replies)

I am using this line of perl code to change the file format and remove ^M at the end of each line in files:
perl -i -pe's/\r$//;' <name of file here>
Can you explain to me what this code does, and translate it into bash/awk/sed? (2 Replies)
@sorted = sort { $a <=> $b } @unsorted;
I am having hard time understanding how this works? I know the output but interested to know the working.
Thanks in advance. (2 Replies)

tap::parser::iterator::array
TAP::Parser::Iterator::Array(3pm) Perl Programmers Reference Guide TAP::Parser::Iterator::Array(3pm)NAME
TAP::Parser::Iterator::Array - Internal TAP::Parser array Iterator
VERSION
Version 3.17
SYNOPSIS
# see TAP::Parser::IteratorFactory for preferred usage
# to use directly:
use TAP::Parser::Iterator::Array;
my @data = ('foo', 'bar', baz');
my $it = TAP::Parser::Iterator::Array->new(@data);
my $line = $it->next;
DESCRIPTION
This is a simple iterator wrapper for arrays of scalar content, used by TAP::Parser. Unless you're subclassing, you probably won't need to
use this module directly.
METHODS
Class Methods
"new"
Create an iterator. Takes one argument: an $array_ref
Instance Methods
"next"
Iterate through it, of course.
"next_raw"
Iterate raw input without applying any fixes for quirky input syntax.
"wait"
Get the wait status for this iterator. For an array iterator this will always be zero.
"exit"
Get the exit status for this iterator. For an array iterator this will always be zero.
