async export and then do something with file

Hi everyone,

I am wondering if I can perform and export asynchronously and then, without
tying up emacs, wait around for the export to finish and then perform some
other task, like upload the file to a server.  Has anyone tried this
before? I think perhaps the easiest thing to do would be to use async.el or
some similar third-party, but I can't tell what the preferred method is. I
would love osme guidance!

Thanks,

Matt

The asynchronous export should be possible and I've seen some proposed
patches for this discussed recently. The challenge is your second part. In other languages,
you could use something like a 'future' (Clojure) or a Promise
(Javascript), but I'm not 100% sure with Elisp. I suspect you would need
to create the async process and use the :sentinal option to pass in a
process sentinal function, which is essentially a function that will run
whenever the status of a process changes. The sentinal would need to
watch for a status change which indicates the process has finished and
then call whatever your post-export actions are.
