I didn't try your package, but from the description it simply allows one
to use the standard Emacs bookmark system, correct?  (I’m surprised it
doesn’t work with org files out of the box).

Such a feature does belong in Org IMO so feel free to start a new thread.

Re: [O] apply attr_html to a whole figure?

[Christian Moe]

I don't think Org syntax provides any way to do this at present, but
ignore the rest of this message if anyone knows better.

Possible workarounds:

1. Wrap your figure in a #+BEGIN_ADDITIONALCLASS...#+END_ADDITIONALCLASS
block, to wrap the div.figure in a div.additionalclass. Not exactly what
you wanted, and a pain in the neck if you have many such figures, but
gives you enough to work with in CSS.

2. Add javascript to move the extra class attribute from the img to
the containing div. 

3. Write an export filter.

Yours,
Christian

The "only" reason was that I imagine that some might prefer not to get
into anonymous faces.  But then, there’s an example right there in the
docstring so maybe it’s assuming too little of our friends...

I’ll remove -OR-BACKGROUND and push.

Looks good, but how do I get the element representation of a parsed
keyword in the :options-alist?

In the buffer, I can do

   (org-export-read-attribute :attr_beamer (org-element-at-point))

But this does not work with what is stored in the info list.

I’m probably missing something obvious here...

It looks like `org-html--wrap-image' should be responsible for using a
proper "figure" element, maybe try edebugging it and see what it's
doing? This may be obvious, but the document has to be exported as html5
before html5-fancy has any effect!

Hi,

I just tried with:

ls -al

But still got the same error. I wonder on which end threw me this error.
Maybe it is because I am using Emacs on Windows, and some thing is missing?
Or maybe it is because the remote system is OpenWRT which has limited

Re: [O] How to use org mode shell with ssh?

[Xi Shen]

Instead of using ssh, I tried with scp. This time I got a different error.

#+BEGIN_SRC shell :dir /scp:openwrt:/mnt/sda1
ls -al
#+END_SRC

The error, I think, is from the remote end.

/bin/sh: /bin/zsh: not found

Clearly, I am using zsh on my Windows, but my remote OpenWRT system only
has ash installed. Is there's way to specify the shell to use on the remote
end?

Try opening the file in tramp directly - that should tell you where the error

Even more: try ssh to your box from the command line. Once you figure out
how that works, then you can teach tramp to use that method.

Re: [O] How to use org mode shell with ssh?

[David A. Gershman]

I'm not familiar with remote execution like this, but are you specifying
/zsh/ on the Windows side or is it somehow inherently being assumed for
the remote?  A quick little hack to try may be to copy the /zsh/
executable on Windows to /ash/ and see if it fools the remote side.

[O] Add org-bookmark-heading to Org proper?

[Adam Porter]

As mentioned in <87oa3gs8tc@gmx.us>, some changes to the org-id
functions are being proposed.  My org-bookmark-heading package uses
org-id-find, so if that function changes or is removed, I'd have to
change the package for newer Org versions.

Given that, now might be a good time to consider merging the package
into Org proper.  It seems like something that should be in Org already,
being able to make Emacs bookmarks that point to Org headings.  It's
actually just three functions, so not much of a "package" really.

https://github.com/alphapapa/org-bookmark-heading

Thoughts?  :)

IIUC, openwrt is the name of the remote node - nothing to do with OpenWrt 
(except of course, that
the remote node may be a router which has been flashed with OpenWrt, but that 
should make no
difference to ssh/tramp).

Re: [O] Babel Export - Getting asked for coding system

[Aaron Ecay]

Hi David,

The way you have this code set up, perl will print a string to its
stdout.  Emacs will read that string into a buffer, then write it to a
file.

It would be simpler to write the file directly from perl.  Note that
this will require specifying the file name twice (in the :file header
and in the perl code).  This is because ob-perl does not support the
:results graphics syntax (which could be classed as a wishlist-type
bug).

Any change to the API would leave in place a compatibility alias for a

Hi Adam,

The package looks useful, and we ought to have this functionality as
part of org.  The first question that arises is whether you have
completed the copyright assignment process described at
: an
assignment is necessary for any patches to org-mode core.

The assignment process takes some time, so (if the assignment is
something you want to do) you can go ahead and get started.  You only
have to go through the process once, and you’re covered for this and
all future contributions to org mode/emacs.

I was expecting that to be the next question.  ;)  I haven't done so

Sorry about that.  I read the list with Gnus through Gmane, and I don't
know of a better way to do it, other than going to the list archive site
and digging up the URL, which seems like a lot of trouble...  ;) AFAIK
you can google the message-ID and get to the thread in question,
although it might be a few days before Google indexes it.
Alternatively, Gnus should be able to access it directly through Gmane
NNTP, and when the new Gmane web interface comes online, that should
work too.

That's one of the reasons I appreciate Org so much (and the Emacs
community in general): stability.  I know that no one will yank the rug
out from under me like that.  :)  I'm not really so concerned about this
proposed change, it just seemed like a good time to mention it.

Just curious, by "major version of Org", do you mean the first digit,
e.g. 8.x.x->9.x.x, or the second digit, like 8.1->8.2?  I guess you mean
the first, semver-style, but Org's been around longer than that spec's
been a "spec", so I thought I'd ask to be sure.

Re: [O] Babel Export - Getting asked for coding system

[David A. Gershman]

Thank you for the explanation.  It turns out I did find a work-around which is 
exactly what you mentioned.  The only difference is instead of specifying the 
file name twice, I was able to get it only once and use the 'file' option to 
:results:

#+BEGIN_SRC perl :results output file :exports results :var fname=image.png
  use GD;
  my $image = build_pic();
  open( F, ">$fname" );
  binmode F
  print F $image;
  close( F );
  print $fname;
#+END_SRC

As you say, this uses Perl to output the file but with the 'file' option to 
":results", Org expects a filename as the output result, I only need specify 
the filename once, and Org will still create a link for the results section:

#+RESULTS:
[[file:image.png]]

Thanks again for your help and info!

Re: [O] XML dump of org file?

Just to add, there are circular dependencies in this data structure due
to ":parent" and potentially some of the ":structure" elements.  They
obviously need to be broken to avoid infinite loops.

Here my hackish attempt to deal with this in order to dump org-element
to JSON:

See org-json-straigten-tree for how I nullified these elements.

I think Org could benefit from a shrunk version of this library, i.e.,
`org-bookmark-make-record' and `org-bookmark-jump'.

However I'm not convinced about `org-bookmark-jump-indirect' since this
variable complicates code and the same effect can be achieved easily
once the destination headline is reached.

Besides, the helm part doesn't really belong to Org. IIUC, it is not
even needed if we drop support for `org-bookmark-jump-indirect', as
suggested above.

A few suggestions, after a cursory look:

- please switch to lexical binding as all but one file in Org core,

- it is "Org mode", not "org-mode"

- `org-replace-links-in-string-with-desc' already exists, it is
  (mis)called `org-link-display-format'

- `assoc' -> `assq' when key is a symbol

- if you create a marker, unset it once useless

- first sentence in docstrings has to fit in the first line.


Thank you for your work.

Re: [O] How to use org mode shell with ssh?

[Fabrice Popineau]

My $0.02

As I'm using Emacs on Windows, with MSYS2+MingW64, I tried this.
There is a problem with using bash from a _native_ MingW64 Emacs:
bash is a MSYS2 app and Emacs is a MingW64 app.

>From emacs, I would have used the plink protocol, so that's what I did.
And I got this message in the *Org-Babel Error Output* buffer

/bin/sh: 1: C:/Local/Emacs/bin/cmdproxy.exe: not found

So I looked at ob-eval.el and the org-babel-eval function.
And there are at least 2 big problems.
1- when entering this function, the `command' parameter is
"C:/Local/Emacs/bin/cmdproxy.exe"
2 - the `shell-file-name' variable has the same value
So the following won't work for Windows :
;; Unfortunately, `executable-find' does not support file name
;; handlers.  Therefore, we could use it in the local case
;; only.
(shell-file-name
(cond ((and (not (file-remote-p default-directory))
(executable-find shell-file-name))
shell-file-name)
  ((file-executable-p
(concat (file-remote-p default-directory) shell-file-name))
shell-file-name)
  ("/bin/sh")))

BTW I don't see the point concatenating shell-file-name with
default-directory when the later is remote.
Do we expect to find the shell in the remote directory ?

Anyway, there is little chance this stuff will work under Windows with a
native Emacs.
If I find time, I may try to propose some fix.

[O] Turn off #+BEGIN_EXAMPLE conversions?

[David A. Gershman]

Hello,

I have some text in an EXAMPLE block but on HTML export '<' and '>' are 
converted to their '&' equivalents.  Is there a way to turn this off on a 
per-instance basis?

For example, I have:

#+BEGIN_EXAMPLE
  T = X + Y1
#+END_EXAMPLE

and I'd like the '1' to be subscript.  But when I write:

#+BEGIN_EXAMPLE
  T = X + Y1
#+END_EXAMPLE

obviously the'<' and '>' are converted to < and >.  "Y_1" also won't 
work. 

Is there a way/option to disable this conversion for that specific block?  Ex:

#+BEGIN_EXAMPLE :nointerpolation
  T = X + Y1
#+END_EXAMPLE

This would let the browser apply the  even though it's in a  
block.

Thanks.

I don't think these functions belong to the API. The seems more like
internal functions, implemented before the "--" convention.

This complicates the API for no real benefit. We ought to consider
`org-id-find' as the sole entry point in "org-id.el". The rest is
implementation details.

More on this below.

In the code base, notwithstanding contrib/ and "org-id.el" itself, there
are 4 calls to `org-id-find' without a marker. Half of them make use of
the position (in org-capture and org-colview.el). If we add
`org-id-find-id-in-file', there are two more calls. One of them actually
require the position anyway (in ob-ref). I don't think 3 calls out of
6 is significant.

If speed is an issue, we can add an optional argument to skip position
(and marker) in the return value. E.g.,

  (org-id-find ID &optional OUTPUT)

where OUTPUT is either

- nil : return value is the usual cons cell (file . position)
- file : return value is the file, as a string
- marker : return value is a marker.

Again, I don't think we need 3 functions just for this.

IMO the former is acceptable. If it happens to disturb some users,
I guess we will fallback to the latter.

[O] Bug with behavior of point in cycle commands?

[Adam Porter]

I came across this discussion today:

http://emacs.stackexchange.com/questions/27210/how-to-prevent-org-global-cycle-glitch

It seems like a bug to me, because the visual position of the point does
not match its actual position.  Shouldn't the cycle commands adjust the
point to match where it appears after cycling?

Yes, the Helm-related code would certainly be left out.  I could propose
a patch to Thierry or make it a separate package on MELPA.

The indirect feature could be left out as well, but I find it so useful
that I think it might be worth including so that users can try it.  It
really transforms the way I use Org, especially in combination with some
other functions I have that use indirect buffers when jumping to items
from the agenda.  It wouldn't need to be enabled by default, of course.
But it's not strictly necessary, so I won't fight you on that if you
want to leave it out.  ;)
