NAME
    IPC::Run::Fused - Capture Stdout/Stderr simultaneously as if it were one
    stream, painlessly.

VERSION
    version 1.000000

SYNOPSIS
      use IPC::Run::Fused qw( run_fused );

      run_fused( my $fh, $stderror_filled_program, '--file', $tricky_filename, @moreargs ) || die "Argh $@";
      open my $fh, '>', 'somefile.txt' || die "NOO  $@";

      # Simple implementation of 'tee' like behaviour,
      # sending to stdout and to a file.

      while ( my $line = <$fh> ) {
        print $fh $line;
        print $line;
      }

DESCRIPTION
    Have you ever tried to do essentially the same as you would in bash do
    to this:

      parentapp <( app 2>&1  )

    And found massive road works getting in the way.

    Sure, you can always do this style syntax:

      open my $fh, 'someapp --args foo 2>&1 |';

    But that's not very nice, because

    1. you're relying on a sub-shell to do that for you
    2. you have to manually escape everything
    3. you can't use list context.

    And none of this is very Modern or Nice

SIMPLEST THING THAT JUST WORKS
    This code is barely tested, its here, because I spent hours griping
    about how the existing ways suck.

FEATURES
    1. No String Interpolation.
        Arguments after the first work as if you'd passed them directly to
        'system'. You can be as dangerous or as safe as you want with them.
        We recommend passing a list, but a string ( as a scalar reference )
        should work

        But if you're using a string, this modules probably not affording
        you much.

    2. No dicking around with managing multiple file handles yourself.
        I looked at "IPC::Run", "IPC::Run3" and "IPC::Open3", and they all
        seemed very unfriendly, and none did what I wanted.

    3. Non-global file-handles supported by design.
        All the competition seem to still have this thing for global file
        handles and you having to use them. Yuck!.

        We have a few global file-handles inside our code, but they're only
        "STDERR" and "STDOUT", at present I don't think I can circumvent
        that. If I ever can, I'll endeavor to do so ☺

EXPORTED FUNCTIONS
    No functions are exported by default, be explicit with what you want.

    At this time there is only one, and there are no plans for more.

  run_fused
      run_fused( $fh, $executable, @params ) || die "$@";
      run_fused( $fh, \$command_string )     || die "$@";
      run_fused( $fh, sub { .. } )           || die "$@";

      # Recommended

      run_fused( my $fh, $execuable, @params ) || die "$@";

      # Somewhat supported

      run_fused( my $fh, \$command_string ) || die "$@";

    $fh will be clobbered like 'open' does, and $cmd, @args will be passed,
    as-is, through to exec() or system().

    $fh will point to an IO::Handle attached to the end of a pipe running
    back to the called application.

    the command will be run in a fork, and "STDERR" and "STDOUT" "fused"
    into a singular pipe.

    NOTE: at present, "STDIN"'s file-descriptor is left unchanged, and child
    processes will inherit parent "STDIN"'s, and will thus block ( somewhere
    ) waiting for response.
