Re: heredoc and carriers return

I can confirm the behaviour in 5.25.5 (built on September 16) on Linux.

#!/usr/bin/perl
use warnings;
use strict;
use feature qw{ say };

my $nix = << '__NIX__';
line 1
line 2
__NIX__

my $win = << '__WIN__'; # ^M present at end of lines.
line 1
line 2
__WIN__

# ^M present here, too:
my $quoted = 'line1
line2
';

say /\r/ for $nix, $win, $quoted;

I can't find it documented anywhere.

Update: It doesn't work for normal quoted strings, either.

($q=q:Sq=~/;[c](.)(.)/;chr(-||-|5+lengthSq)`"S|oS2"`map{chr |+ord
}map{substrSq`S_+|`|}3E|-|`7**2-3:)=~y+S|`+$1,++print+eval$q,q,a,

I suppose it's related to Perl being OS agnostic regarding \n when printing. Please check the hex code of the here doc to see what is really embedded. Edit: OK seems like the regex is supposed to do this. Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply]

> I can't find it documented anywhere I'm to busy now, but you might wanna look into `open` which mentions a IO layer called `:crlf` or `encoding` or other docs mentioned in the footnotes ... Cheers Rolf _{(addicted to the Perl Programming Language and ☆☆☆☆ :) Je suis Charlie!}	[reply] [d/l]

Neither open nor encoding describe how they influence Perl's parsing of multiline string literals. ($q=q:Sq=~/;[c](.)(.)/;chr(-\|\|-\|5+lengthSq)`"S\|oS2"`map{chr \|+ord }map{substrSq`S_+\|`\|}3E\|-\|`7**2-3:)=~y+S\|`+$1,++print+eval$q,q,a, [download]	[reply] [d/l]
