bug#38010: 26.1; Please support creating a remote temporary file with Tramp

[Markus Triska]

I am working on an Emacs application that spawns a remote process via
start-file-process. That process will use a remote file that should
ideally be generated in analogy to a local temporary file as can be
obtained with make-temp-file.

Specifically, the application is ediprolog, and there is user demand for
extending it to work with remote Prolog processes:

    https://github.com/triska/ediprolog/issues/4

Hence, it would be really useful if for example make-temp-file could be
extended to create a temporary file on the remote machine.

Thank you and all the best!
Markus

There is `make-nearby-temp-file' for that purpose.

I'm closing the bug as "notabug". Feel free to come back if it doesn't
work for you.

Thank you Michael! I did not see this mentioned anywhere in the Tramp or
Emacs documentation, and so, could you please consider documenting it?

Thank you and all the best,
Markus

Thank you, I found it now in the documentation!

All the best,

Tramp is just a library which offers alternative implementations for
Emacs functions. It does not document which functions it implements,
that's part of the Emacs doc.

I don't have Emacs 26.1 at hand, just 26.2. It documents
`make-nearby-temp-file' in:

- /etc/NEWS
- the elisp info, see (info "(elisp) Unique File Names") and
  (info "(elisp) Magic File Names")

I suggest to add an index entry there.  For example:

  @cindex temporary file on a remote host

This might make this function more discoverable.

Good idea. Done, and pushed to master.

Best regards, Michael.
