Since this thread made the Ruby Weekly News wrap-up, I feel obliged to
Can you talk to an open pair of pipes from Vim? I didn’t think you
could keep a live connection to another process in Vim in this way,
hence my convoluted socket-based architecture.
No, named pipes (a/k/a fifo). To run a debugger command (perhaps
Ahh, those named pipes. ;^) So I did a little more digging, plugging
a few holes in my own knowledge of nitty-gritty I/O in the process. Best

I would like to keep the solution entirely in Ruby/VimL source. See
