NAME
Syntax::Feature::Qn - Perl syntax extension for line-based quoting
SYNOPSIS
use qn;
@foo = qn {
line one
line two
line three
};
# ("line one", "line two", "line three")
$bar = 'BAR';
@foo = qqn {
foo
$bar
bam
};
# ("foo", "BAR", "bam")
DESCRIPTION
This module adds line-based quoting operators to Perl, similar to
here-docs, but without the required outdenting.
The qn() and qqn() operators are drop-in replacements for q() and qq(),
respectively. The same delimiter rules apply.
The quote body is split on "\n" and each resulting list item is stripped
of leading and trailing whitespace. Inner whitespace is preserved.
Empty lines, or lines consisting of only whitespace, translate to empty
string list items.
The first and last items can be on the same line as the delimiter, or
not. So, these are the same:
@foo = qn {
first
second
third
fourth
};
# ("first", "second", "third", "fourth")
@foo = qn { first
second
third
fourth };
# ("first", "second", "third", "fourth")
You could even get away with this:
@foo = qn { first };
# ("first")
