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.
I fail to understand, why this is a problem, but you should
be able to work around that using the writefile() function,
which seems to be better suited for such a case.
BTW: I think this is rather a topic for vim_use and not vim_dev.
Best,
Christian
