bug#24292: # Local Variables: not working

[nullx002]

+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++

My init.el file has following line:

(gobal-linum-mode t)

Now I want to disable linum-mode for few .org files so i used following:

# Local Variables:
# eval: (linum-mode 0)
# End:

in header above everything else.

but it is not working for me for org files, it works for other files
like .txt .md .js etc. but not for .org files

I tired with empty .org file and result is same.

C-h v linum-mode for .txt file gives:

Its value is nil
Local in buffer test.txt; global value is the same.

while,

C-h v linum-mode for .org file gives:

Its value is t
Local in buffer capture-tasks.org; global value is nil

            ^^^^^

Assuming nothing's got lost in the translation, that could be your
problem.  the Local Variables: section has to come at the BOTTOM of the
file, after other things.

It will work as long as it's within the last (I think) 5000 character of
the file.  So if you've got some fairly short files, a LV section at the
top of that file will work.  If your file is bigger than ~5000 bytes
(and I think .org files tend to be big) it won't work.

So move those LV sections to the ends of their files, and see if that
helps.

Glad to hear it!

This is where your removal of the bug list address from the Cc: counts
against you.  I actually know nothing about org mode, but other people
reading the list actually know quite a lot.

However, I looked into the org mode manual, and see you can write
comments by starting a line with "#".  The "Local Variables:" line is
quite happy being after a comment marker, so you could write your LV
list entirely in org mode comments:

    # Local Variables:
    # ...
    # End:

Just one or two tips on getting quick help in the future.  Your post
would have been more appropriate on help-gnu-emacs@gnu.org, since it was
not clear that it was an actual Emacs bug.  (As it turned out, it
wasn't.)  Please, as already mentioned, leave in the list address when
you reply.  That way, more people get to see the problem, and there is a
complete record of the thread in the archives.

Anyways, I hope you can now get things sorted out, and continue being a
happy Emacs user.  :-)
