Hi,
sorry for this offtopic mail, but I asked this on the vim-user
mailing list and git no answer...
What I wnat to do seems to be simple: I want to write a script
with vim and -- without saveing it -- pass it to the ruby interpreter
and get back the output including stderr AND stdout back into a new
buffer.
this.possible? && if true
聽聽anser = how.ask(self)
end
Evening.nice!

I pulled this from the web, or the mailing list, somewhere..... a google on it should point you to the correct author...
in .gvimrc/.vimrc add
map <C-I> :!rm -f /tmp/*put<C-M> :w /tmp/input<C-M> :!/bin/ruby /tmp/input > /tmp/output 2>&1<C-M> :vs +e! /tmp/output<C-M><C-W>l
map <C-L> <C-W>o
short form of descriptions
<CTRL-I> execute and paste results in left side of vertical split
<CTRL-L><CTRL-W> close left side of vertical split
I've wanted this myself, but never quite got there.
* You can use :w !ruby to run the current buffer without saving it and
see the output.
* You can use :r !ruby % to run the current buffer AFTER saving it and
and get it's output to the same buffer.
* You can use :e to open new buffers
I've never found a good way to bring them together into a nice round
trip shortcut, and unfortunately I don't know if they'll suit your needs
anyway since :r still writes out a temporary file...

Thanks a lot for that trick, Reid ! 
But this only write the buffer, start ruby, exute that file with ruby
with ridirected output to another file and reads back that file into
vim. Additionally it does not check, whether both files already
exist...thex will be overwritten simply.
I wanted to exeute ruby with the buffer contents without writing to
the disk at all for that reason.
Is this possible ?

I can get you stderr and stdout mised together, not in separate files:
0G"ryG:new
"rp:%!ruby
This yanks the entire buffer into register r, opens a new window, pastes
register r into the window, feeds the entire buffer into ruby's stdin and
replaces the buffer with what the script writes to stdout or stderr.
Unfortunately, I don't know how to distinguish between output to stdout and
stderr. Since you are writing the script, however, you should know which is
which.

I inserted the above mapping into $HOME/.vimrc .>
In a buffer I wrote:
#!/usr/bin/ruby
print "hallo"
and pressed <Ctrl-R>
An error pops up saying:
E499: Empty file name for '%' or '#', only works with ":p:h"
(dont know before, that the error message are in Chinese ... ;O)
And now ?

Sorry to respond to my own post, but this is a much nicer-looking (and
tested!) version of the above:
:%y r|new|pu r|%!ruby

I hope that someone finds a solution to this, because I would like to
add somethign to my .vimrc that can do what you want.

How about
:vmap <C-R> y:exe "ruby " . getreg()<CR>
Mark some text in visual mode and press <C-R> to send it to the builtin Ruby interpreter. Note that the interpreter isn't restarted upon each invocation, so previous definitions stay valid, which may or may not be what you need.

Pit
Here's one idea + cheap implementation:
* F7 in visual mode evaluates the selected area; temporary files are used so
the original one isn't overwritten. The output (stdout & stderr) is shown in
a new vsplit window (on the right)
* F7 in normal and insert modes evaluate the whole buffer; the cursor position
is preserved (warning: overwrites the 'z' mark)
* S-F7 kills the stdout/stderr buffer; it is also removed from the
minibufexplorer
function! Ruby_eval_vsplit() range
let src = tempname()
let dst = tempname()
execute ": " . a:firstline . "," . a:lastline . "w " . src
execute ":silent ! ruby " . src . " > " . dst . " 2>&1 "
execute ":redraw!"
execute ":vsplit"
execute "normal \<C-W>l"
execute ":e! " . dst
execute "normal \<C-W>h"
endfunction
vmap <silent> <F7> :call Ruby_eval_vsplit()<cr>
nmap <silent> <F7> mzggVG<F7>`z
imap <silent> <F7> <ESC><F7>a
map <silent> <S-F7> <C-W>l:bw<cr>
