Re: Can a Perl module "inspect" itself and provide details about methods and parameters?

Just a couple of data points, as others have discussed the overall issues with XS, AUTOLOAD and the like. Neither will process argument lists, so they only address part of the question.

Devel::Symdump will give a huge amount of information about packages, but I prefer Class::Inspector these days as it is simpler to use.

use Devel::Symdump;
my $obj = Devel::Symdump->rnew( $package_name ); 
my @methods = $obj->functions();
#  if you are sure private methods only start with underscore...
my @public_methods = grep {$_ !~ /^_/} @methods;

and

use Class::Inspector;
my $methods = Class::Inspector->methods( $package_name );
my $public_methods = Class::Inspector->methods( $package_name, 'public
+' );

Cool! Using a regex stolen from Class::Inspector: CORE functions: `perl '-MData::Dumper()' -e '@_=sort grep {/\A[^\W\d]\w\z/o} keys %{"$ +{CORE}::"};print Data::Dumper::Dumper\@_'` [download] CORE + Cwd import: `perl '-MData::Dumper()' -MCwd -e '@_=sort grep {/\A[^\W\d]\w\z/o} key +s %{"${CORE}::"};print Data::Dumper::Dumper\@_'` [download] Everything: `perl '-MData::Dumper()' -e '@_=sort keys %{"${CORE}::"};print Data::Du +mper::Dumper\@_'` [download]	[reply] [d/l] [select]

> CORE functions: nope these are some plain named symbols in the %main:: STASH since your var $CORE is undef. Anyway you need to check the `{CODE}` slot of the glob-values to be sure that they hold a code-ref. `DB<30> sub test { "bla" } DB<31> x map { \&$_ } grep {defined &$_ } values %:: 0 CODE(0x3477178) -> &main::test in (eval 40)[C:/Perl_524/lib/perl5db.pl:737]:2-2 1 CODE(0x3463838) -> &main::dumpvar in C:/Perl_524/lib/dumpvar.pl:474-501 2 CODE(0x3457a78) -> &main::dumpValue in C:/Perl_524/lib/dumpvar.pl:33-40 DB<32>` [download] dumpvar and dumpValue are internal debugger routines Cheers Rolf _{(addicted to the Perl Programming Language :) Wikisyntax for the Monastery FootballPerl is like chess, only without the dice}	[reply] [d/l] [select]
