org-pdfview-open doesn't work anymore

[Julien Cubizolles]

I've been using org-pdfview (from
https://github.com/markus1189/org-pdfview) to have org-mode open pdf
files generated during export.

--8<---------------cut here---------------start------------->8---
(pdf-tools-install)
(eval-after-load 'org '(progn (require 'org-pdfview)
			      (add-to-list 'org-file-apps '("\\.pdf\\'" . org-pdfview-open))
			      ))
--8<---------------cut here---------------end--------------->8---

Since a recent upgrade, this fails with:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

Is it a bug in Org-mode or should I report the issue to the org-pdfview
author ?

Due to lexical binding in org.el there was a change in
`org-file-apps', see Org News for version 9.0 and e. g. this thread:
http://thread.gmane.org/gmane.emacs.orgmode/104272
I think the most convenient would be if `org-open-file' tries to find
out that `cmd' in this case is a function with only one argument and
call it with just `file'.

@Nicolas: Is this reasonable for you to implement?

I think the simplest solution may be to follow the advice in ORG-NEWS
and use

  (lambda (file link) (org-pdfview-open file))

Only after a closer look I saw that the single parameter of
`org-pdfview-open' is not `file' but `link'. It is probably better for
`org-open-file' to not guess in case of `cmd' with a single parameter
whether it is meant to be `file' or `link'. That leads me to suggest
the attached patch to be reviewed that checks the function signature.

I have the feeling there is some over-engineering involved there. 

In any case, instead of relying on `help-function-arglist', I suggest to
use something lightweight:

(condition-case err
    (funcall ...)
  (wrong-number-of-arguments
   (user-error "Please ..."))
  (invalid-function
   (user-error "Please ...")))

Also it should have allowed at least optional arguments

    (when (or (memq
               ;; Too complicated to parse regarding that such functions
               ;; are probably not useful here.
               '&rest
               arglist)
              (/= 2 (length (delete '&optional arglist))))
      (user-error

for e. g. a simple

    (add-to-list 'org-file-apps
                 (cons (concat org-player-file-extensions-regexp "$")
                       'org-player-play-file))

which refers to the existing

    (defun org-player-play-file (filename &optional pos)

Of course. I didn't know about this possibility, remixed patch attached.

(user-error
 "Please see Org News for version 9.0 about `org-file-apps', error: %S"
 (nth 1 err))

You can use continuation character (i.e., "\" followed by a newline) if
string is too large.

The above does not provide (nth 0 err) which is the important error
type and (nth 2 err) which I find also helpful. See following zerop
examples.

What am I missing that it should not be

    ((wrong-number-of-arguments wrong-type-argument invalid-function)
     (user-error "Please see Org News for version 9.0 about \
`org-file-apps'--Lisp error: %S" err))

to get

    Please see Org News for version 9.0 about \
    `org-file-apps'--Lisp error: (wrong-number-of-arguments zerop 2)

    Please see Org News for version 9.0 about \
    `org-file-apps'--Lisp error: (wrong-type-argument numberp nil)

from

    (condition-case err (zerop nil nil) ...)

    (condition-case err (zerop nil) ...)

to mimic

    Debugger entered--Lisp error: (wrong-number-of-arguments zerop 2)

    Debugger entered--Lisp error: (wrong-type-argument numberp nil)

from

    (zerop nil nil)

    (zerop nil)

as far as possible?

I just notice that in our case at least in case of wrong-type-argument the
`cmd' is missing, so I suggest

    ((wrong-number-of-arguments wrong-type-argument invalid-function)
     (user-error "Please see Org News for version 9.0 about \
`org-file-apps'--Lisp error: The function %S leads to %S" cmd err))

for the attached intermediate patch version. For the above example of
(zerop nil) it would not only report "wrong-type-argument" and
"numberp" together with "nil" but also "zerop" which in our case is
the registered application, the source of the problem where the user
needs to look.

IMO, notifying user that there's something rotten in the state of
`org-file-apps' is enough. There's no need to go into the gory details
of the problem.

Anyway, if you feel strongly about it, your patch looks good and you can
push it.

Thank you.

I agree and finally found what I was missing: Add `debug' to the
handler of `condition-case' to finally not disable support of further
investigation with `toggle-debug-on-error'. It obsoletes my trials to
provide enough context about the Lisp error in the handler itself.
Remixed patch for review attached.
