Re: Parsing multiline string line by line

Or you can use the same file-access mechanisms to access the string if a reference to the string is passed to open() instead of a file name:

>perl -wMstrict -e
"my $filelike = qq{Line 1\nLine 2\nLine etc.\n};
 open my $fh, '<', \$filelike or die $!;
 while (<$fh>) {
   print
   }
 close $fh or die $!;
"
Line 1
Line 2
Line etc.

Ooh! A new thing! I never knew this before. (It's not mentioned in the crib-sheet page I tend to use.) Does it do anything with references to other types as well? -- use JAPH; print JAPH::asString();	[reply]

The manpage for open gives open FILEHANDLE,MODE,REFERENCE as a way to call open, but, oddly, neither the manpage nor perlopentut seems to discuss it further (as far as I can see from a very quick scan of those two documents). Anyone know where this may be discussed?	[reply]

aha! i saw doing it this way a long time ago in some code online, and remembered that it was possible, but figured i'll find it again when I need it... but i couldn't find any examples again! thank you very much! :-)	[reply]
