[O] Show presence of zero width spaces using overlay

[Kaushal Modi]

Hi all,

The suggestion to use zero width spaces to sort of "escape" stuff in org
mode has come up many times. I have started using it a lot and suggest that
to other people now.

Here is one such recent QnA on emacs.SE:
http://emacs.stackexchange.com/a/16702/115

The OP of that question made a valid point that while using zero width
spaces is convenient, it is not apparent where it has been used in the
document.

To resolve that, I am requesting a feature.

Can the zero width spaces be optionally represented with something like a
single space overlay with a colored background (like purple)?

Making this officially part of org-mode will probably make more people make
use of it.

.. Or should people use zero width spaces?

[O] [PATCH] fix SETUPFILE pathname expansion with subdirectories

[Richard Hansen]

* lisp/org.el (org--setup-collect-keywords): cd to the directory
containing the SETUPFILE before recursing so that relative pathnames
in the SETUPFILE are expanded properly.

* lisp/ox.el (org-export--get-inbuffer-options): cd to the directory
containing the SETUPFILE before recursing so that relative pathnames
in the SETUPFILE are expanded properly.

If /path/to/foo.org contains:

#+SETUPFILE: settings/beamer.org

and /path/to/settings/beamer.org contains:

#+SETUPFILE: common.org

then we want to read /path/to/settings/common.org, not
/path/to/common.org.

Python works this way.  But babel R has a completely different *this*
value.  Consider the following example:

  #+BEGIN_SRC R :results output graphics :file line.png :dir /ipmuap02:/tmp
  plot(c(1,2,3))
  #+END_SRC

  #+RESULTS:
  [[file:/scp:ipmuap02:/tmp/line.png]]

*this* equals "[[file:/scp:ipmuap02:/tmp/line.png]]", but in babel
python *this* equals "line.png".

So I come up with

  #+name: localize
  #+BEGIN_SRC emacs-lisp :var file="" srcinfo=(org-babel-get-src-block-info)
(let ((lang (car srcinfo)))
  (cond ((string= lang "python")
 (let* ((dir (cdr (assoc :dir (nth 2 srcinfo
(rfile (concat (file-name-as-directory dir) file))
(lfile (car (last (split-string rfile ":")
   (copy-file rfile lfile 1)
   lfile))
((string= lang "R")
 (let* ((rfile (substring file 7 -2))
(lfile (car (last (split-string rfile ":")
   (copy-file rfile lfile 1)
   (concat "[[file:" lfile "]]")
  #+END_SRC

But the result is a string rather than a file link:

  #+HEADER: :post localize(*this*)
  #+BEGIN_SRC R :results output graphics :file line.png :dir /ipmuap02:/tmp
  plot(c(1,2,3))
  #+END_SRC

  #+RESULTS:
  : [[file:/tmp/line.png]]

Any hints?

Thanks for your explanations - I am not using macros regularly (not
yet...) so I was not aware of these aspects.

I was just using macros as an example - I am not advocating to change
macros if this would change something. A simpler option would be
possibly to use properties. Assuming I have the following properties defined:

,
| #+PROPERTY: headerArgsForTangline :tangle ./testfile.R
| #+PROPERTY: headerArgsForSession :tangle no :session *MyRSession*
| #+PROPERTY: headerArgsForNoSession :tangle no
`

then I could do

,
| :header-args*: headerArgsForSession 
`

and the header arguments would be set to the value of
headerArgsForSession and be ":tangle no :session *MyRSession*".

This would make it possible to define sets of header arguments for
certain aspects (one example I would use it for: creating graphs and
define the width and height properties. Depending if I want portrait or
landscape graphs, I would use the one or the other property and they
could be ca=hanged easily for the whole document.)

Cheers,

Rainer

[O] Bug: cached code blocks should return the same value [8.3.1]

[Benda Xu]

Hi All,

Passing values across code blocks makes Org babel a powerful meta
programming language:

   #+name: input
   #+BEGIN_SRC sh :results output
   echo "3"
   #+END_SRC

   #+BEGIN_SRC R :var a=input()
   a
   #+END_SRC

   #+RESULTS:
   | 3 |
   |   |

However, this feature does not work with cache.  In case that "input"
code block takes a long time to evaluate, it is a good idea to cache the
result.  But that returns "nil" in subsequent function calls:

   #+name: input
   #+BEGIN_SRC sh :results output :cache yes
   echo "3"
   #+END_SRC

   #+RESULTS[f69ecd305ebd448fc39b05809d214261a777c6bc]: input
   : 3

   #+BEGIN_SRC R :var a=input()
   a
   #+END_SRC

   #+RESULTS:
   : nil

Recalling the cached function should return exactly the same result by
definition of "cache".

Or is there a way to circumvent this by referring to the "RESULT" field
directly?

Cheers,
Benda

Have you looked at exporting the sub-tree?  If you define the
appropriate EXPORT_xxx properties in the sub-tree, it should be
equivalent to having that sub-tree as a file alone.  Check the export
options at the top of the help window when you type "C-c C-e ?"

Any hints?



Forget *this* and use the

(cdr (assoc :file (nth 2 srcinfo))

to get the file name.  That should work the same way regardless of 
language.

Here's the MWE once again with proper indication ([ZWS]) of where you need
to insert the zero width space char.

=

* Escaping =equal= sign in verbatim formatting.
=a\equal{}b+c=
** Here's the same but using zero width spaces instead of /org entities/.
=a=[ZWS]b+c=

* Here I am trying to have double quotes in verbatim formatting.
=\quot{}This is inbetween double quotes\quot{}=.
** Here's the same but using zero width spaces instead of /org entities/.
=[ZWS]"This is inbetween double quotes"[ZWS]=.

* And here's to escapes asterisks
This is *bold*. But this is \ast{}not bold\ast{}.
This works!

Re: [O] Show presence of zero width spaces using overlay

[Kaushal Modi]

Thanks for letting me know about org-entities. That is awesome. I now know
how to escape various characters in general, but unfortunately this does
not work within verbatim formatting (which makes sense).

Here's a minimum working example:

=

* Escaping =equal= sign in verbatim formatting.
=a\equal{}b+c=
** Here's the same but using zero width spaces instead of /org entities/.
=a=b+c=

* Here I am trying to have double quotes in verbatim formatting.
=\quot{}This is inbetween double quotes\quot{}=.
** Here's the same but using zero width spaces instead of /org entities/.
=​"This is inbetween double quotes"​=.

* And here's to escapes asterisks
This is *bold*. But this is \ast{}not bold\ast{}.
This works!

Entities can be used to escape most Org syntax, e.g. 

  \ast{}shrug\ast

I see no compelling reason to treat zero width spaces specially.

would it be possible to put the selection and a tab dentifier in a

maybe that makes no sense.

It should. There is a new ELPA release every week.

This should be fixed too. Thank you.

Re: [O] Show presence of zero width spaces using overlay

[Kaushal Modi]

My most common uses are escaping double quotes (") and equals (=) within
org verbatim blocks (=VERBATIM=)

Examples:

1. =var=[ZWS]val=
2. =[ZWS]"something"[ZWS]=

Here [ZWS] is the 0x200b zero width space unicode char.

I found [ZWS] useful as a generic escape char for org mode. There are few
other cases where this has been useful, but I can't recall right now.

In any case, what would be the recommended way to escape " and = in the
above 2 examples?

[Arun I]

Just in case, I have also attached a tarball with org files and emacs
source code to reproduce the error.

Just extract the tarball, and run

emacs -Q -l minimal-org.el

in the extracted folder. If the load file paths and org file paths are
set correctly as mentioned in minimal-org.el, the org-babel-tangle-publish
bug should show up.

So this is what you are talking about:

(defun org-babel-sh-strip-weird-long-prompt (string)
  "Remove prompt cruft from a string of shell output."
  (while (string-match "^% +[\r\n$]+ *" string)
(setq string (substring string (match-end 0
  string)

Bearing in mind that my pattern-matching experience is mainly from Perl,
I don't get the regex above.  Isn't it just going to match a prompt
starting with a '%' followed by a bunch of spaces, carriage returns /
newlines, and more spaces?  That may be both weird and potentially long,
but isn't it quite a specific subset of weird, long prompts?

Cheers,

Loris

Org plot is there for quick and easy plotting.  I would recommend using
babel with gnuplot source blocks.  You can easily pass tables as data,
and configure your plot as you wish.  Unfortunately I have not done this
recently, so I don't have any simple examples handy, but I'm sure there
are plenty on Worg.

Hope this helps,

Hello Samuel,

So, not so wonderful..  I just found out how to reproduce this problem.

Open a page with two frames, for example:

http://www.quackit.com/html/templates/download/preview.cfm?template=../frames/css_frames/frames_2_column_left_menu.cfm

And pressing C-a (Select All) for the selection.

And then capture the page.

Please note that you can not select the text in both frames using the
mouse.

> and sometimes it will capture the link but not the
> selection.

Do you have an example page for this?  Once we have a really simple
example page with the error we can report a bug!

> it will also sometimes capture something else you copied,
> which does not appear on the page whose link gets capture.

Yes, I saw a note in the code, the /problem/ is that firefox does not
clean the selection when you change tab.  So you select something in tab
1, switch to tab 2 and you get the link and page title of page 2 and the
selection of tab 1.  Maybe there are workaround, like force the cleaning
of the selection after a tab change, but this can impact the user
experience.  I guess that usually you expect the selection to persist
until you paste it, even if you have changed tab, or not?  Coping from
tab 1 and paste in tab 2 is not an exotic use case.

I think that the selection is global and not per tab.  Maybe is possible
to add a selection per tab, by listening to some events.

Another limitation of the selection in firefox is that can not span over
frames and over 3rd party injection of content (not sure on how they do
this those days) but in a page with content and disqus.com you can not
select and capture both with the mouse. And if you use C-a you will bump
into the previous problem.

Hope you find this information useful,
Daniele

[O] Bug: org-babel-tangle-publish fails in copy-file step [8.3.1 (release_8.3.1-241-gea7ac0 @ /home/arunisaac/.emacs.d/org-mode/lisp/)]

[Arun I]

When publishing files using org-babel-tangle-publish, if the :tangle
header argument is given to a source block, and if org-babel-tangle-publish
is called from a directory other than the directory in which the source
file (that is, the file being tangled) exists, then org-babel-tangle-publish
fails in the copy-file step.

This happens because org-babel-tangle returns the file name (that is,
the basename only) mentioned in the :tangle header argument, and
org-babel-tangle-publish tries to copy that unqualified basename
instead of the absolute path to the file.

My emacs configuration follows. I used the minimal configuration given in
the Feedback section of the org mode manual. The backtrace for the error is
also attached.

Thanks,
Arun Isaac.

I see what you mean, but I believe something like

is still pretty simple and yet so powerful.
