I would like to write a script that can run an external application and handle its STDERR and STDOUT on the fly while supplying STDIN. My script and the external application should not block each other. I also need to make sure the two output channels are captured separately.

I looked around on CPAN and found Capture::Tiny to be one of the best tools for capturing the STDOUT and STDERR and it also list a lot of other modules that do similar tasks. I just could not figure it out yet how can I do what I wanted. Anyone here with an example for such task?

Update

Oh yes, and it needs to work on Windows, Linux and Mac OSX.

The end user of this project will be Padre - and this seems to be the major blocking before we can add an interactive debugger.
