Re^4: What is the preferred cross-platform IPC module?

[Theory]

I don't have Windows, and besides, that would completely defeat the purpose: I don't want to have to think about platform issues or any error-handling beyond trapping exceptions. I want a module that does all that for me. I like IPC::System::Simple, for example, which appears to do a nice job of it if all I want to do is system or backticks. IPC::Run may or may not succeed in doing it for interactive IPC, I'm still trying to figure that out.

Sorry, for trying to help.

My experiences of using IPC::Run on windows are dire. It is an over-engineered behemoth of a module that attempts to use *nix techniques to provide *nix capabilities on Windows, and fails dismally.

The point about winopen2 is that it provides you with a pair of selectable handles connected to the child process' STDIN & STDOUT.

As such, it is 'compatibile' with *nix-style code written using IPC::Open2 and select.

Ie. you'd only need do something like:

my( $in, $out );
if( $^O eq 'MSWin32' ) {
    ($in, $out ) = winopen2( $theCommand );
}
else {
    open2( $in, $out, $theCommand );
}

...

select .....

But, its not in a module so ...

I appreciate the help. That doesn't look bad, but then what does one do about error handling? Can errors from the child caught? At exec time? After that? That's what I imagine a module would take care of.

I agree about IPC::Run. I am just surprised that there isn't a decent solution to this problem. Must come up all the bloody time…

It seems to me that your response of

besides, that would completely defeat the purpose: I don't want to have to think about platform issues

conflicts with

I started implementing the module I have been imagining,

that was stated in the node that was being responded to.

At least, I expect that creating a module that saves users from having to deal with "platform issues" that they would otherwise have to deal with pretty much requires that the author "think about [those] platform issues".
