    I am doing perl development on a Solaris x86 platform, which isn't a supported eclipse platform.  I see that there is some support within EPIC for remote run/debug scripts.   Is this feature in a state that it could be used for day to day perl development?  Or, is this meant for single use purposes?

      There is support for remote debugging, but not so much for remote running (you're supposed to launch your scripts on the remote machine using a wrapper provided by EPIC - this is not as convenient as local launching). You have to take care to keep your remote and local files synchronized. This is easy for project files, but not so easy for entire Perl installations. So you may run into problems when stepping into/through remote modules in a different version than your local one - their displayed source is taken from the local installation, not from the remote machine.

      You might also encounter firewall issues (remote debugging requires connectivity from the remote machine to the Eclipse one). You can set up ssh port forwarding ports for 5000-5003 to work around this.

      Generally, I think it's better to write and test portable Perl code on the supported platform, but don't be afraid to use the remote debugging functionality if/when you run into problems on the remote machine.

      Thanks for the quick reply and I understand. 

      It is probably like oil and water, but would RSE help EPIC remote debugging?

        Yes, I think integrating RSE + EPIC would be a good idea. Conceptually, there is no difference between remote debugging of C programs and remote debugging of Perl programs, and as far as I know, RSE is designed to be a general framework. An advantage of EPIC (concerning installation, upgrades, and conceptual simplicity) is that it has no dependencies besides of the core Eclipse platform. I think it might be a good idea to rely on RSE "behind the scenes", but a bad idea to require EPIC users to become aware of RSE.
