Your package doesn't match the filename, see Simple Module Tutorial , the filename should match the package name.

Instead of comments write documentation :) Tutorials: POD in 5 minutes and maybe

See Modern Perl and Class::Inspector AND Howto create a Moose baseclass/superclass/contract? Moose equivalent of Module::Pluggable? Favorite way to create base/super class?

You might start with

module-starter --author="David Luu" --email=man...mail.com --license=LGPL --module=RobotRemoteServer,RobotRemoteServer::Frontier,RobotRemoteServer,RobotRemoteServer::RPCXMLServer

Then maybe write something like


package RobotRemoteServer;
use Class::Inspector;

sub get_keyword_names { my ($self) = @_; my $class = $self->lib; my @methods = Class::Inspector->methods( $class, 'public' ); return \@methods; } sub run_keyword { my $self = shift; my ($stdout, $stderr) = capture { ... }; } sub start_server { my $self = shift; $self->backend->start_server; }

package RobotRemoteServer::Frontier; sub _shut_down_request { RobotRemoteServer::Frontier sub start_server { my ($self) = @_; my $svr = Frontier::Daemon->new( methods => { get_keyword_names => sub { $self->get_keyword_names(@_) }, run_keyword => sub { $self->run_keyword($_[0], eval{@{$_[1]}}) } +, stop_remote_server => sub { $srv->_shutdown('yes please'); $self->schedule_shutdown; return; }, .... } sub schedule_shutdown { my $self = shift; my $url = $self->url; if( eval { require threads; } ){ threads::async { sleep 5; require Frontier::Client; Frontier::Client->new( 'url' => $url )->call('stop_remote_s +erver'); }; } elsif( eval { require Proc::Background; } ){ Proc::Background->new( $^X, '-e', q{ use Frontier::Client; sleep 5; my $url = shift @ARGV; Frontier::Client->new( 'url' => $url )->call('stop_remote_server'); exit; }, $url, ); } } sub Frontier::Daemon::_shutdown { my( $self, $true ) = @_; ${*$self}{'_Frontier::Daemon::_shutdown'} = !!$true if $true; return ${*$self}{'_Frontier::Daemon::_shutdown'} ; } sub Frontier::Daemon::accept { ## monkeypatch package Frontier::Daemon; my $self = shift; if( $self->_shutdown ){ close $self; return; } else { return $self->SUPER::accept; } }

To handle shutdown in similar way as https://robotframework.googlecode.com/hg/tools/remoteserver/robotremoteserver.py you could monkeypatch shutdown, but writing your own frontier deaemon ( Frontier::Daemon::Forking ) is probably the correct way to do it

backend is the new argument, RobotRemoteServer::Frontier by default

use RobotRemoteServer; #my $rob = RobotRemoteServer->new (qw' host localhost port 666 '); my $rob = RobotRemoteServer->new (qw' host localhost port 666 backend Frontier lib ExampleLibrary '); $rob->start_server;

Maybe it makes more sense for backends to be named as RobotRemoteServer::Backend::Frontier ...

But that is a start, pod beats comments, seperate backends into seperate modules, use existing modules for introspection , has-a not isa-a ...

Future direction:
maybe Moo/Moose or Badger for accessors/mutators...
Maybe POE server ( ex Hopkins::Plugin::RPC ), ex?Catalyst::Plugin::Server::XMLRPC, Plack for ideas
maybe cooperation with Daemon::Generic, AnyEvent::XMLRPC, ...

If I were more knowledgeable, I might make better suggestions ;)
