I don't really see the issue...  Can we add a proper Version headers in

Re: [O] Automatically encrypt on save, decrypt on open?

[John Kitchin]

They are basically copied from thetop of
http://orgmode.org/worg/org-tutorials/encrypting-files.html

The first line loads epa-file (epa-file.el --- the EasyPG Assistant,
transparent file encryption )

The second line looks like a way to call epa-file-enable if it hasn't been
enabled. You can just call epa-file-enable, and it does the check too, but
this probably avoids a minibuffer message when it is already loaded. I
think this function provides a handler for files ending in .gpg which need
to be en/decrypted by gpg.

Re: [O] Pass options to \columns{} environment in beamer export

In the tutorial under "Special environments"[1], I see the following
paragraph:

  All contiguous environments are automatically wrapped in a columns
  environment, although it can be forced at any point by setting the
  BEAMER_env property to columns. This might be handy if you want to
  pass special options.

Do you think it could be worded more clearly?  When I wrote the article
(which is quite a while back :-p), I was trying to be complete without
being too verbose.  While working on your project, if you think of
improvements to the article, please feel free to make the changes.  The
article is in desperate need of updates.  I have a long list of
additions, if only I could find the time.

It simply because it Just Works (TM) with those 3 lines which I have in

`org-cycle-internal-local' calls `org-show-children', which is the Org
specific implementation of `show-children'.

I don't think orgstruct details should leak into `org-show-children', so
I suggest to plug orgstruct stuff, i.e., make sure `show-children' is
called instead of `org-show-children', elsewhere. 

One possibility is to use a hook in `org-cycle', not sure which one
though. `orgstruct-mode' could also assume its kludge status and use
something like `add-function'.

WDYT?

Of course, here we go. Please let me know if there's anything wrong

We don't generate org.el; while it would not be impossible to do, I
don't really see why we should just to drop some comment in there.
Besides, it would be perfectly possible to just install the .elc files
(not with package manager, but some Linux distributions actually do
this) and then where do you look for the version comments again?

In my setup (and I didn't do anything special, just installed gpg from

I have this: (add-to-list 'auto-mode-alist '("\\.org\\'" . org-mode))).

Re: [O] 8.3 hangs

[Samuel Wales]

i am still getting a lot of hangs in 8.3.  most often, it is when i do
a subtree sort.

i keep trying element debug mode, but it has magical bug preventing abilities.

org-show-entry is another place where the bug occurs.  it is part of
recreating a more folded state after undoing a sort.

once it was like

Debugger entered--Lisp error: (quit)
  org-element--cache-compare
  avl-tree--do-delete
  avl-tree--do-delete
  avl-tree--do-delete
  avl-tree--do-delete

  org-element--cache-process-request
  org-element--cache-sync(# 31756)
  org-element-at-point()
  org-cycle-hide-drawers(children)
  org-show-entry()

anybody else getting these hangs?

Re: [O] 8.3 hangs

[Samuel Wales]

it might not be sorting itself.  after i sort, i do org-show-entry as
part of a sequence to try to make things a little more folded after a
sort.

Definitely, and I can take a stab at it now that I understand how it
works. I think what didn't register was the meaning of "contiguous
environments." I'm not really sure how to parse that.
- What is an "environment" (as in any of the b_xxx properties causes
it to be in a columns env. as well)?

- What is "contiguous" (I think I now understand this to mean
"nested.")? I guess I tend to think of contiguous as "of the same
part," which didn't immediately register as "parent/child." That said,
I think I *did* try putting the columns env property on my first level
headline, but that didn't work. I needed:

* Top
** Columns property
*** actual column 1
*** actual column 2

Sorry this is taking me a while...

I'm still trying to get exactly what's going on here -- you haven't been
able to use helm with org at all, so you set those refile values in
order to disable helm when refiling, but with gnorb it tries to go back
to using helm and fails, is that right?

Gnorb provides the option `gnorb-gnus-trigger-refile-targets', which is
basically exactly the same as `org-refile-targets', it just allows you
to adjust how/which headings are proposed as for the gnorb trigger
process. Maybe you can try setting that to the same value as your
current `org-refile-targets', and see if that helps?

Hmm, I should probably be doing that by default...

If I were you, though, I'd be looking more closely into why helm isn't
working with org! It's pretty useful... If you use helm with
`org-refile-get-location', do you not see any headings at all? Or you
see them but typing does nothing?

Environment here refers to what is exported to LaTeX.  Since the
previous paragraph was talking about "column", I mean these blocks:

  \begin{column}
  ...
  \end{column}

I think the important bit to understand (in general about the beamer
exporter), the properties are what determine the exported LaTeX
environment.  The tags are there for the convenience of the user.  The
BMCOL tag is the exception, no other tag behaves this way.  There is
another special tag, B_ignoreheading, but there the purpose is to end
the previous environment, rather than export a new one.

> - What is "contiguous" (I think I now understand this to mean

The dictionary meaning of contiguous is something that shares a
boundary, or adjacent.  Maybe a more common, but less specific, word is
easier to follow, say something like adjacent or consecutive.  Is the
meaning clearer if contiguous is changed to one of these?  

Would a more verbose explanation, maybe with an example, be better?
Either way, please feel free to make the change :).

[O] M-x org-publish in 8.3.1 results in error "org-check-agenda-file: Wrong type argument: stringp, nil"

[Omid]

Hello,

In Emacs 24.5.1, after updating to the latest Org mode in ELPA
(8.3.1-16-gf6aa53-elpa), org-publish results in the error

"org-check-agenda-file: Wrong type argument: stringp, nil"

on a project that used to publish without errors using the latest Org 8.2.

Here is the part of a backtrace of the error (using M-x
toggle-debug-on-error) that I believe is relevant

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

  command-execute(org-publish record)
  execute-extended-command(nil "org-publish")


I had to remove the arguments of byte-code() because they contained
special characters that couldn't be pasted in email.

Searching for this error, the only instance I could find was at

https://lists.gnu.org/archive/html/emacs-orgmode/2014-11/msg00343.html

reporting a the same error message, but the solution suggested there
is already implemented in 8.3 as a fix and is not applicable in this
case.

The relevant part of org.el is


(defun org-check-agenda-file (file)
  "Make sure FILE exists.  If not, ask user what to do."
  (when (not (file-exists-p file))
(message "Non-existent agenda file %s.  [R]emove from list or [A]bort?"
 (abbreviate-file-name file))
(let ((r (downcase (read-char-exclusive
  (cond
   ((equal r ?r)
(org-remove-file file)
(throw 'nextfile t))
   (t (user-error "Abort"))


How can I solve this problem?

Thanks,

Omid
