Hello!
I have some VimL where I write the current buffer to a temporary file like this:
let tmp = tempname()
execute 'keepalt silent write' tmp
I then use the temporary file in an external command invoked with system().
Finally I delete the temporary file:
call delete(tmp)
At no point do I load, or want to load, the temporary file into a vim buffer.
However every time my VimL executes, a new buffer number is taken because the
temporary file is allocated an unlisted buffer (visible with :ls!). How can I
prevent Vim allocating buffers for my temporary files?
For example:
1. Open some file in Vim. This is loaded into buffer 1.
2. Execute my VimL ten times.
3. Open some other file.
Desired behaviour: "some other file" is loaded into buffer 2.
Actual behaviour: "some other file" is loaded into buffer 12.
Many thanks in advance,
Andy Stewart
