Sub::Inspector - get infomation (prototype, attributes, name, etc) from a subroutine reference
use Sub::Inspector; # get file, line, name (oo interface) use File::Spec; my $code = File::Spec->can('canonpath'); my $inspector = Sub::Inspector->new($code); print $inspector->file; #=> '/Users/Cside/perl5/ ... /File/Spec/Unix.pm' print $inspector->line; #=> 71 print $inspector->name; #=> 'canonpath' # class method interface print Sub::Inspector->file($code); #=> '/Users/Cside/perl5/ ... /File/Spec/Unix.pm' print Sub::Inspector->line($code); #=> 71 print Sub::Inspector->name($code); #=> 'canonpath' # get prototype use Try::Tiny qw(try); print Sub::Inspector->proto(\&try); #=> '&;@' # get attributes use AnyEvent::Handle; my $code2 = AnyEvent::Handle->can('rbuf'); print Sub::Inspector->attrs($code2); #=> ('lvalue')
This module enable to get metadata (prototype, attributes, method name, etc) from a coderef. We can get them by the buit-in module, B.pm. However, it is a bit difficult to memorize how to use it.
NOTE: You can call each method whether as instance method or as class method.
