org-eldoc and shell

Hi,

In org-eldoc.el, org-eldoc-get-mode-local-documentation-function function,
there is this code:

(with-temp-buffer
            (funcall mode-func)
            (setq doc-func (and eldoc-documentation-function
                                (symbol-value
'eldoc-documentation-function)))
            (puthash lang doc-func org-eldoc-local-functions-cache))

Unfortunately, this code does not work for shell-mode.
Especially, if you get a temp buffer and try to turn it into shell mode,
you get an error because there is no associated process.

Emacs 25.1 uses this in the shell-mode function to find which shell:
(let ((shell (file-name-nondirectory (car
  (process-command (get-buffer-process (current-buffer))))))

but if there is no process, get-buffer-process returns nil and
process-command fails.

I am only reporting this because I am not sure what to do about it
But surely it is a bit annoying that
<s TAB shell
runs into error every time.

Regards,

Fabrice

Hi Fabrice,

shell-mode is a shell emulation mode – what you get when you type M-x
shell.  You should use sh (or bash, as applicable) in the header line of
your src blocks.

But shell-mode is working and I get a cmd.exe prompt (because I'm using
Windows).

And it seems to work ok with both sh and bash.

Thanks for your help.
