Re: Multiline Hash - how to get rid of formatting?

Syntax::Feature::Ql is close to what you want. It gives you a quote-like operator ql such that:

use syntax 'ql';
use Test::More tests => 1;

my $greeting = ql{
  Hello
  World
};

is($greeting, q{Hello World});

Following the same technique you could create a quote-like operator which trims whitespace from the start of each line but preserves line breaks.

If you're happy just to adjust the string with a regular expression though, you're probably looking for:

s/^\s+//mg

This is quite cute... `use 5.010; use strict; QTRIM_SETUP: { my $trimmer; BEGIN { $trimmer = sub ($) { @_ = map { s/(^\s+)\|(\s+$)//g; $_ } split /\n/, shift; shift until length $_[0]; pop until length $_[-1]; join "\n", @_; } } use PerlX::QuoteOperator qtrim => { -emulate => 'q', -with => $t +rimmer }; use PerlX::QuoteOperator qqtrim => { -emulate => 'qq', -with => $t +rimmer }; } my $string = qtrim{ Hello World }; say "[$string]";` [download] Obviously, if you were doing this in "real life" you'd move the QTRIM_SETUP block into a module, so that you could just do: `use 5.010; use strict; use PerlX::Qtrim; my $string = qtrim{ Hello World }; say "[$string]";` [download] There's a slight annoyance with `qqtrim` in that this: `my $embedded = "\n \n"; my $multiline = qqtrim{ Hello $embedded World };` [download] ... will also end up stripping the spaces in `$embedded` which is somewhat counter-intuitive. `perl -E'sub Monkey::do{say$_,for@_,do{($monkey=[caller(0)]->[3])=~s{::}{ }and$monkey}}"Monkey say"->Monkey::do'`	[reply] [d/l] [select]

sorry, but I think this will set the OP off on the wrong trajectory. I think the problem is confusion about the usage of data structures and formatting in script files vs. formatting that Perl sees.	[reply]
