EWW via TRAMP no working

EWW via TRAMP no working

[H. Dieter Wilhelm]

Hello GNU-Emacs-26.3

We, me and another colleague of mine, are trying to read HTML
documentation with eww-open-file-via TRAMP located on a remote server.

We are able to open the files with TRAMP, for example:

   /ssh:wawa:/tmp/Hlp_C_FINISH.html

is working, but we are getting the following error message with EWW:

    url-file: File does not exist:
    file:///ssh:wawa:/tmp/Hlp_C_FINISH.html

Is there a workaround to make EWW run with remote files?

Thank you

This cannot work, because eww doesn't know such a local file
"/ssh:wawa:/tmp/Hlp_C_FINISH.html".

There is url-handler-mode, but I doubt that eww cooperates with
it. Something like

(eww-open-file (file-local-copy "/ssh:wawa:/tmp/Hlp_C_FINISH.html"))

seems to work. Maybe you could compose an interactive command around
this snippet.

I see, still looks promising.  Maybe an EWW luminary will give futher
comments on it before I have time to test it.  Or if it necessary to
write a bug-report and asking for an EWW enhancement or so..

Love it, thank you very much for this helpful workaround Michael!

It won't hurt to write such a feature request (aka bug report). No idea,
whether somebody will handle it.

It's still a workaround. References to relative files won't work, I fear.

Best regards, Michael.

I think I'll do that in a week or so, if url-handler is not working for
our use case.

Damn it!  I forgot that, you are right, this is really ugly.

`M-x eww-open-file' with a Tramp file name should work, and it doesn't.
It bugs out with a most odd error:

Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil)
  url-file-asynch-callback(nil nil nil "/:/ssh:stories:/home/larsi/.emacs.d/bookiez.data" #<buffer  *url-file*-73983> eww-render (nil "file:///ssh:stories:/home/larsi/.emacs.d/bookiez.d..." nil #<buffer *eww*>))

  url-retrieve("file:///ssh:stories:/home/larsi/.emacs.d/bookiez.d..." eww-render ("file:///ssh:stories:/home/larsi/.emacs.d/bookiez.d..." nil #<buffer *eww*>))

  eww-open-file("/ssh:stories:.emacs.d/bookiez.data")
  funcall-interactively(eww-open-file "/ssh:stories:.emacs.d/bookiez.data")

So please go ahead and file a bug report on this.
