unable to create/find a .cpp file (ed.2)

[Gary Wessle]

Hi

after my first post, I here provide more info in-order to find a fix.
thank you for giving me your time to fix my problems.

C-h f mailcap-parse-mimetypes function does not have any ".cpp" entry:

$emacs -q (the problem DOES NOT returns)

Yes, but did you check each of the files listed in that function's
doc string?  That is where the ".cpp" -> "more '%s'" association must
be coming from since it's not in extview-application-associations.

But I think you could override the mailcap/mimetypes association like
this:

(setq extview-application-associations
       (cons '("\\.cpp\\'" . nil) extview-application-associations))

> $emacs -q --no-site-file (the problem goes away)
> $emacs -q (the problem DOES NOT returns)

That means the source of the problem is either ~/.emacs or default.el,
but we already know it's just because you're loading the extview library
from ~/.emacs.

sorry, but I don't get it, "function's doc string"
C-h f mailcap-parse-mimetypes output did not give any file names
either.

sorry, that fix just above will let me open an existing .cpp file but
will not let me create a new one. as well as it will fail find/create
.h files

Sorry, I meant the files listed in its source code (including
$MIMETYPES, e.g.):

     (cond
      (path nil)
      ((getenv "MIMETYPES") (setq path (getenv "MIMETYPES")))
      ((memq system-type mailcap-poor-system-types)
       (setq path '("~/mime.typ" "~/etc/mime.typ")))
      (t (setq path
	      ;; mime.types seems to be the normal name, definitely so
	      ;; on current GNUish systems.  The search order follows
	      ;; that for mailcap.
	      '("~/.mime.types"
		"/etc/mime.types"
		"/usr/etc/mime.types"
		"/usr/local/etc/mime.types"
		"/usr/local/www/conf/mime.types"
		"~/.mime-types"
		"/etc/mime-types"
		"/usr/etc/mime-types"
		"/usr/local/etc/mime-types"
		"/usr/local/www/conf/mime-types"))))

Exactly what happens when you try to visit a new .cpp file?

sorry, I meant to say, I can visit a new .cpp file fine now but
visiting a new file.h I get in the *extview log*

Opening file ~/myPrograms/backtest/man.h with handler: more '%s'
/home/fred/myPrograms/backtest/man.h: No such file or directory

Process extview-process finished

****************************************************************

I thought to add a bit extra to what you suggested by doing in my
.emacs the following

(setq extview-application-associations
       (cons '("\\.cpp\\'" . nil) extview-application-associations),
       (cons '("\\.h\\'" . nil) extview-application-associations))

and then restart emacs and trying to visit a new .h file but I still
get the same error i.e, adding the .h line above to my .emacs did
nothing.

Your MIME configuration is broken, not Emacs.  Check ALL the mime.types
files I listed for you.  It seems there is a default entry that maps
every file extension to the more '%s' command; you could verify that
by visiting a file with a nonsensical extension, e.g. "abc.foobarbaz".

what command do I use to get the list of the above files on my system?

looking for any "cpp" in the above files, I found

in ****************	"/etc/mime.types"
text/x-c++src					c++ cpp cxx cc

I don't have most of the files you listed above.
I also don't have any $MIMETYPES in my $env output.


$ locate mime*.src

Sorry, there is no command.  I browsed extview.el, whose find-file
advice led me to mailcap.el, whose mailcap-parse-mimetypes function
contains that code.

I guess somewhere else "text/x-c++src" is mapped to "more '%s'".  Can
you see anything suspicious in the output from `C-h v mailcap-mime-data' 
?  My guess is there's a default entry for the "text" major type.

That's normal.

Find out where that last entry  is added (~/.emacs, default.el,
site-start.el) and delete it.

are you referring to this

    (viewer . "more '%s'")
    (type . "text/*")
    ("needsterminal" . t))

by just looking at the files "default.el" does not exist here, I could
not locate anything obvious, what is the exact "string" shall I be
searching for?
