How can you insert the output of an Ex command into the

1) use :redir to a register and paste the register

Strange that there isn't a simpler method built-in.
I totally agree with you. Would be much more simpler if we could wrote
something like:
:<echo 25*47
And the output was directly put in the current buffer in the cursor position.
The sequence "redir 'something'", type a command and then 'redir END' is
really to much to do when we need to be fast. To get the result of the
calculation above is much more easy just "see" the value in the command window
and write it by your hand in the buffer.
This is a feature that a miss in Vim/GVim for quite sometime.
you can insert the output of every VimL expression with
<C-R>=your-expression-goes-here<CR>
while you are in insert mode. Your example would then be typed as
<C-R>=25*47<CR>
While this works for expressions (the followup question about
"echo 25*47"), it doesn't satisfy the OP's request for arbitrary
Ex commands. Assuming the commands to be executed don't include
redirs and there's not a redir already in process (that you don't
want to terminate), it could be wrapped in a function
function! Capture(excmds)
redir => s:results
exec a:excmds
redir END
return s:results
endfunction
You could then use the function in concert with the expression
register:
<c-r>=Capture('scriptnames')
(odd results if you don't have 'paste' set) in insert mode, or
you can use
"<c-r>=Capture('scriptnames')<cr>p
to paste it in normal mode. The command should also work with
multiple pipe-separated commands:
Capture('scriptnames|set')
Hope this helps,
