Re^2: yaml dynamically load in perl

Thanks a lot for your inputs. Would check tied hash later.

And could you show my how to call the 'CODE' or 'ref' in Yaml.

For instance, Here is Yaml format: cmd:!perl/ref my_print

Perl Code:

$my_print = sub { print "howdy"; };
[download]

How do I make 'cmd' to call $my_print after load the Yaml file into $conf like:

&{ $conf->{"cmd"} }
[download]

To make it run and print "howdy".

Not sure if this answers your general question, but here are some specific alternatives: `c:\@Work\Perl\monks>perl -wMstrict -le "my $my_print = sub { print qq{howdy @_}; }; ;; my $conf = { 'cmd' => $my_print }; ;; &{ $conf->{'cmd'} }; $conf->{'cmd'}->('there'); $conf->{cmd}('doody'); " howdy howdy there howdy doody` [download] Give a man a fish: `<%-{-{-{-<`	[reply] [d/l] [select]

The point is that we need work with Yaml format: cmd:!perl/ref my_print Not directly with perl anonymous subroutine.	[reply]
