Annoyance when running scripts in Vim (Windows, Ru

Question

I started using vim for my programming projects (mostly Ruby) and mostly everything works just as I want but I have a problem with compiling.

Lets say I am working on a Ruby script and I want to run it. I type :ruby sometging.rb (mapped to some other key). Then vim opens a new cmd.exe window and runs 'ruby something.rb'. Then it waits for me to press ENTER to close the window and continue working on the script.

Is there a way to configure vim on windows so that it always runs the script I'm working on in a separete window (always the same one, if none exists => open one), and not ask me to confirm with enter?

Answer 1

This isn't exactly perfect but I use this to launch Python scripts.

command -nargs=* PY3 !start cmd /K Python.exe "%:p" <args>

It starts up a window that stays alive and doesn't interfere with my VIM window. Unfortunately it doesn't load it into an existing window.

Don't know about gvim, but in normal vim you could put something like

map R <ESC>:tabnew<CR><ESC>:;%!ruby filename.rb<CR>

in your ~/.vimrc which would execute a Ruby file in a newtab when pressing R in command mode.

I've not used Ruby, but for I've found Dr Chip's RunView plugin really useful for running other interpreted languages.

Once it's installed, you can enter:

:RunView! <interpreter>

(where <interpreter> is presumably 'ruby' in your case) and it will open a (vertically if you include the !) split window with the output from passing the contents of the current window to the interpreter. Each time it is run, a new result log is appended to the end of the file (with a date and time stamp separating them).

If you have any issues with it, I'd recommend you contact Dr Chip via the Vim mailing list: he's very helpful (in fact he wrote the original version of RunView in response to a request I made on the mailing list).
