org-mode (recent git) tries to open .c and other plaintext file:// links with less on debian

org-mode (recent git) tries to open .c and other plaintext file:// links with less on debian

[Friedrich Delgado Friedrichs]

Hi!

I just wondered why my file links to c-sources would not work any more:

 [[file:~/anon-vc/emacs/src/emacs.c::fatal_error_signal%20sig][file:~/anon-vc/emacs/src/emacs.c::fatal_error_signal sig]]

until I looked what org-open-file does with edebug and noticed it
tries to handle the file according to its mailcap entry.

Which is, on my debian testing systems:

text/plain; less '%s'; needsterminal

which makes a lot of sense when I try to open a plaintext file
attachment e.g. with mutt.

From emacs, not so good.

Indeed, M-x list-processes lists a less process:

Proc                                     Status   Buffer Tty        Command
----                                     ------   ------ ---        -------
less /home/fdf/anon-vc/emacs/src/emacs.c run      (none) /dev/pts/6 /usr/bin/zsh -c less /home/fdf/anon-vc/emacs/src/emacs.c

Example of failing link

I just revisited the same experienmce with 6.35e.
All of my links give the same results but one example is

[[file:apoptosis.org::*Topics][Topics and Ideas]]

Just down loaded and install 6.35 from web site. Running XP and emacs. When trying to follow link I get an error
ShellExecute failed.  Moved back to 6.34c and everything works fine.

Thanks.

Hi Paul

I think this is fixed with the current git master - please check.

Hiho!

Confirmed fixed (for me) with recent git. Thanks! ;)

I didn't notice that this issue was double-posted:
