Re: [Orgmode] Handling file links under Windows

[Leo Alekseyev]

Guided by Matt's suggestion I started digging further.  I see the
problem, but I don't know how to fix it other than by making crude
changes directly to source in org.el.

Both the command path and the file link path need to be properly
formatted for Windows.  In particular, in org-file-apps list, I need
something like ("\\.jnt\\'" . (format "%s %%s" (w32-short-file-name
"C:\\Program Files\\Windows Journal\\Journal.exe"))).  But, this
expression doesn't work verbatim.  If I evaluate (format....) and
paste the result as the cdr of the dotted pair, e.g. ("\\.jnt\\'" .
"c:/PROGRA~1/WI0FCF~1/Journal.exe %s"), the command is invoked.  So,
question 1: How do I eval the (format...) expression automatically?..

A more serious problem is that emacs is failing to correctly convert
slashes to backslashes in the file path.  My emacs is launched by
cygwin, and so apparently it thinks that slashes are OK, but in fact
they are not.  Here are the explicit modifications to org-find-file in
org.el that are needed to get things to work:

Original code (doesn't work under Windows):
(setq cmd (replace-match
                   (save-match-data
                     (shell-quote-argument
                      (convert-standard-filename file)))
                   t t cmd)))

Here's what works:
(setq cmd (replace-match
                    (w32-short-file-name (save-match-data
                                           (convert-standard-filename
                                            (replace-regexp-in-string "/" "\\" 
file t t)))) t t cmd))

Note that instead of (convert-standard-filename file) I need to
explicitly replace slashes with backslashes, and shell-quote-argument
must be replaced with w32-short-file-name.  So, question 2: Is there a
way to make these modifications without patching org?..
