Hi everyone
I am not even a novice at Perl scripting .. but had to edit one the other day. The only way I can get it to run is by prefixing 'perl' before running it - ie # perl scriptname
I am running AIX.
Any ideas why i have to do that ?
Thanks! (2 Replies)

YAML::XS(3pm) User Contributed Perl Documentation YAML::XS(3pm)
NAME
YAML::XS - Perl YAML Serialization using XS and libyaml
SYNOPSIS
use YAML::XS;
my $yaml = Dump [ 1..4 ];
my $array = Load $yaml;
DESCRIPTION
Kirill Siminov's "libyaml" is arguably the best YAML implementation. The C library is written precisely to the YAML 1.1 specification. It
was originally bound to Python and was later bound to Ruby.
This module is a Perl XS binding to libyaml which offers Perl the best YAML support to date.
This module exports the functions "Dump", "Load", "DumpFile" and "LoadFile". These functions are intended to work exactly like "YAML.pm"'s
corresponding functions.
CONFIGURATION
$YAML::XS::UseCode
$YAML::XS::DumpCode
$YAML::XS::LoadCode
If enabled supports deparsing and evaling of code blocks.
$YAML::XS::QuoteNumericStrings
When true (the default) strings that look like numbers but have not been numified will be quoted when dumping.
This ensures leading that things like leading zeros and other formatting are preserved.
USING YAML
::XS WITH UNICODE
Handling unicode properly in Perl can be a pain. YAML::XS only deals with streams of utf8 octets. Just remember this:
$perl = Load($utf8_octets);
$utf8_octets = Dump($perl);
There are many, many places where things can go wrong with unicode. If you are having problems, use Devel::Peek on all the possible data
points.
