Great! Thanks,

I think you missed Node Properties - they are still located under 
Elements on Syntax page


https://orgmode.org/worg/dev/org-syntax.html#Elements

https://orgmode.org/worg/dev/org-syntax.html#Node_Properties

I think it should be moved to Greater Elements section

And it is also listed as Element on API page

https://orgmode.org/worg/dev/org-element-api.htm


I have also discovered more:

Syntax page states:

> With the exception of inlinetasks 
, items 
, 
planning 
, 
clocks 
, 
node properties 
 and table 
rows , every 
other element type can be assigned attributes.


But  this list is not full - if you check the source code 
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L3866


   ;; Item. +
   ;; Table Row. +
   ;; Node Property. +
   ;; Headline.
   ;; Sections (must be checked after headline).
   ;; Planning.+
   ;; Property drawer.
   ;; Paragraph.
   ;; Clock. +
   ;; Inlinetask. +
;; From there, elements can have affiliated keywords.

So Pragraph, Property Drawer, Sections and Headlines are missing from 
this list

[O] org-element discovered inconsistensies

[ihor]

So these are things that I have discovered so far:

    Property Drawer:
   - Element in 
https://orgmode.org/worg/dev/org-element-api.html#orgf47acc7
 It also states that it has :properties field which is simply 
not there in the code

https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L1514
 My assumption in is that Property Drawer contains Node 
Properties directly, as children, instead of :properties filed


   - Greater Element in 
https://orgmode.org/worg/dev/org-syntax.html#Property_Drawers
   - Greater Element in source code 
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L233



 Node Property:
   - Element in 
https://orgmode.org/worg/dev/org-syntax.html#Node_Properties

   - Missing from https://orgmode.org/worg/dev/org-element-api.htm
   - Greater Element in source code 
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L226


 Line Break:
   - Object in https://orgmode.org/worg/dev/org-syntax.html#Line_Breaks

   - Object in source code 
https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L239


Secondly, function that collects affiliated keywords 
(|org-element--collect-affiliated-keywords) |


https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L3988

does not take  granularity 
(https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L4076)

and parse objects any way:

https://code.orgmode.org/bzg/org-mode/src/master/lisp/org-element.el#L4036

Hi Org community.

I am re-posting my questions here according to Nicolas' recommendation.

I am working on a standalone parser implementation for Org which is basically a

There are couple of things I wanted to ask about:

1) I have discovered several inconsistencies and errors in the Syntax/API 
documentation
https://orgmode.org/worg/dev/org-element-api.html vs 
https://orgmode.org/worg/dev/org-syntax.html vs elisp source
And I don't know the right way to report them.

2) I think I have found a bug in the algorithm (org-element-collect affiliated 
keywords does not take granularity into accound and seems to be always parsing 
objects in Caption
keyword)

3) I have a question regarding the elisp source source (specifically about the 
:parent of the parsed objects of the keyword)

I can elaborate on each point but I don't want to overwhelm everybody with 
details right from the start. I guess the meta-question is where and how
should I discuss these points? - I never used mailing lists before (If I did 
something incorrectly or do not follow the established rituals/traditions 
please do not judge me harshly.
)


No need for metaquestions: ask away.

You might want to report related problems together, but if the
connection is tenuous or non-existent, then separate posts to the
mailing list will probably work better. Asking your question in a
separate post is probably best, so it doesn't get lost in the forest
of detail when reporting problems.

If you suspect a bug, then use 'M-x org-submit-bug-report`: the bug
report will end up here and will contain a lot of information about
your set-up which might be helpful.

Finally, be patient: do not expect answers (particularly when the
questions are complicated, as it seems yours will be). It takes
a while for people to get around to even reading the posts, let
alone coming up with answers (or, as is likely, more quesions for
you).

And welcome to mailing lists in general and this mailing list in
particular!

Properties in headlines elements are just references to the real

a property drawer element.

You can modify `property-drawer' and `node-property' elements instead.

[O] Org-element-put-property, bug?

[Ivan Tadeu Ferreira Antunes Filho]

If I put a custom property in a headline, e.g.
(org-element-put-property headline :EXPORT_FILE_NAME "a")

Then, when accessing the org element headline it shows: :EXPORT_FILE_NAME a

However, when I proceed to interpret the data,
(org-element-interpret-data headline)

The custom property does not exist in the properties drawer.


Is there a way of modifying custom properties of a headline by using
org-element, and have the custom properties show up when interpreting the

adopt, otherwise, insert before it.

[O] org-element-adopt-elements, append before children

[Ivan Tadeu Ferreira Antunes Filho]

At the moment  org-element-adopt-elements always appends the new elements
after the elements original children.  In many cases one might want to
append before the original children.

I want to propose adding an argument to org-element-adopt-elements that
defines if the elements should be added before or after the children, i.e.
(if append-before
  (nconc children (org-element-contents parent))
  (nconc (org-element-contents parent) children))

Would this be okay?

Out of curiosity, why is it "more" consistent to return paragraph here?

Notwithstanding this case, if `org-element-at-point' returns
`special-block', you /know/ that you are either on block boundaries
(#+begin_special or #+end_special) or on any affiliated keyword above,
but /never/ within the block.

If `org-element-at-point' returns `special-block' here, you create an
exception, which you have to handle later on.

Besides, the truly empty contents are

  #+begin_special
  #+end_special

therefore, I'm not shocked if

  #+begin_special
  
  #+end_special

is a special block with an empty paragraph instead.

Hi,

Is there a reason why org-element-at-point reports the type to be a
paragraph for special blocks?  E.g. in the examples at the bottom of this
mail, where | is the cursor, the types are: export-block, src-block and
paragraph with a nested special block.

Is there a neat way to detect if point is inside a block?  I’m trying to
write a function for structures (e.g. #+begin_latex) that works like
org-babel-demarcate-block.

This is a corner-case. `org-element-at-point' returns the closest
element at point, but prefers to see an empty paragraph than a special
block, for consistency. I.e., when point is within block boundaries, you
never return `special-block'.

[O] (org-element-context) :end property

[Thomas S . Dye]

Aloha all,

I've started to use John Kitchin's unlinkify function, which he posted
to the list last year.

(defun jk/unlinkify ()
  "Replace an org-link with the description, or if this absent, the path."
  (interactive)
  (let ((eop (org-element-context)))
(when (eq 'link (car eop))
  (message "%s" eop)
  (let* ((start (org-element-property :begin eop))
 (end (org-element-property :end eop))
 (contents-begin (org-element-property :contents-begin eop))
 (contents-end (org-element-property :contents-end eop))
 (path (org-element-property :path eop))
 (desc (and contents-begin
contents-end
(buffer-substring contents-begin contents-end
(setf (buffer-substring start end) (or desc path))

However, I get different results depending on whether the link ends with
a space or a character, e.g.

Foo [[http:www.tsdye.com][desc]] bar.
Foo [[http:www.tsdye.com][desc]], bar.

Foo descbar.
Foo desc, bar.

How can I fix this?  I'm guessing that org-element-context sets :end
differently depending on the character following the link?

All the best,
Tom

White spaces following an object are included in the object. They are
stored in :post-blank property. You can add them with

  (setf (buffer-substring start end)
(concat (or desc path) 
(make-string (org-element-property :post-blank eop) ?\s)))

Re: [O] org-element-at-point keep-trail?

Jonathan Leech-Pepin jonathan.leechpe...@gmail.com writes:

 Previously, org-element-at-point had an optional keep-trail variable that
 was supposed to show the siblings, parents, aunts/uncles, grandparents, etc.

 This feature no longer seems to be present.

 What would the process be now to obtain the parents of a given
 element?

  (org-element-property :parent element)

 This would be useful for walking back up the tree to obtain a sparse-tree
 structure for archiving (see:
 http://lists.gnu.org/archive/html/emacs-orgmode/2014-10/msg00228.html)

Note that `org-element-at-point' doesn't parse ancestors of headlines.
You need `org-element-parse-buffer' for that.

 Best,

 Have you looked at this page?

 http://orgmode.org/worg/dev/org-element-api.html

 That and the pages linked from it seem to cover most of what's going on.

 The mysterious plist holds all the properties for a given element. Most
 are generated by the parsing process (eg :contents-begin and
 :contents-end, see the link above for all the different properties the
 various elements/objects might get), while headlines will also have
 their actual property-drawer properties put into the list.

 The only thing that remains a little opaque to me is the section
 element, which apparently gets wrapped around a heading's subtree. I
 don't know what it does, but it's never gotten in my way so I haven't
 worried about it.

in simple terms, the data structure is just:

,
| (element-typ (plist) (section))
`

i.e. the plist describes the element itself, the section is its
content. 


* TODO Test :@home:
  DEADLINE: 2014-10-09 Do
  :PROPERTIES:
  :ARCHIVE:  foo
  :END:


org-element-at-point does not parse the contents of an element, it
thus simply returns

,
| (element-typ (plist))
`


#+NAME: foo
#+BEGIN_SRC emacs-lisp
 (save-excursion
 (outline-previous-heading)
 (org-element-at-point))
#+END_SRC

# [:results pp]
#+results:

#+NAME: bar
#+BEGIN_SRC emacs-lisp :var x=foo 
 (org-element-interpret-data x) 
#+END_SRC

#+results: bar
: * TODO Test :@home:

so this is (just) the element (headline) as specified by its plist.

You can get the contents e.g. with 

#+BEGIN_SRC emacs-lisp :results wrap
(require 'org-dp-lib)

#+END_SRC

with section recursively containing other elements with the same
structure - a nested list.

 No, it isn't.

 couldn't a more robust construct be used, either something
 like this (untested) regexp:

 ,
 | [^[:space:]\\n]+
 `

 AFAIK, [:space:] is not compatible with XEmacs. It could be [^
 \r\t\n]+, but even this could be too broad (e.g., #+BEGIN_...). We
 could also limit block names to alphanumeric characters and a bunch of
 symbols.

I noticed this issue again when calling `org-element-at-point` with
point before the stars in 

,
| ** [#A] whatsup :mytag:it:
| hello world
`

in an emacs-lisp-mode buffer - it results in:

,
| (paragraph (:begin 193 :end 246 :contents-begin 206 :contents-end 245
| :post-blank 1 :post-affiliated 206 ...))
`

so it kind-of works outside org major-mode, but not correctly due to
character-class problem in the regexp(s).

PS

My org-mode is up to date

Again, `org-element-at-point' is not meant to be used outside of an Org

get bitten sooner or later.

I would support that, since the current regexp limits the function's use
unnecessarily to text-modes.

I have no strong argument (real use-case) for making
`org-element-at-point' work with programming-modes too, except the
'principle of least surprise' - I was surprised that my formerly working
`org-dp-wrap-in-block' suddenly did not work anymore when playing around
with it in the *scratch* buffer and spend some time debugging my code,
only to find out that there was no bug but the input from
`org-element-at-point' was not what I expected.

[O] org-element-at-point fails in programming-modes

[Thorsten Jolitz]

Hi List,

with point at the beginning of each of the following blocks,
`org-element-at-point' does recognize the correct type when buffer is in
org-mode and other text-modes, but not so in programming modes, e.g. the
*scratch* buffer (lisp-interaction-mode). Then only the src-block is
recognized correctly, all the others are parsed as paragraphs.

* ORG SCRATCH

#+BEGIN_QUOTE
hallo world
#+END_QUOTE

#+BEGIN_COMMENT
hallo world
#+END_COMMENT

#+BEGIN_EXAMPLE
hallo world
#+END_EXAMPLE

#+BEGIN_SRC emacs-lisp
hallo world
#+END_SRC

Although Org functions are of course made only for working in org-mode
and its a bit hard to see at first sight how this could be useful, I
wonder if the regexps could be made a bit more general to make
`org-element-at-point' work in programming modes too (most likely this
behaviour is caused by references to character-classes that differ in
text-modes and programming-modes)?

 wonder if the regexps could be made a bit more general to make
 `org-element-at-point' work in programming modes too (most likely this

The reason is that a newline has the endcomment syntax in programming
modes, but has whitespace syntax in text modes. So the regexp
\\+BEGIN_\\(\\S-+\\) (which can be found in org-element.el) matches
e.g. +BEGIN_QUOTE\nhallo instead of just +BEGIN_QUOTE.
(\\S- means anything that doesn't have whitespace syntax)

You could wrap your code in a (with-syntax-table org-mode-syntax-table
...) and cross fingers, or simply do the (org-element-at-point)
computations in a temporary (org-mode) buffer.

I also see the problem. I suspect that it happens when Gnus fontifies

correct (i.e. has the newlines).

While, if you look at the raw message (C-u g, in Gnus), I see well that
you had separated the blocks.

If Nick does not see the problem, that must be a bug in our configs?

 Note that it is a contrived example: the whole buffer is a single
 paragraph containing around 150 objects. The current algorithm for
 `org-element-context' is clearly not on par with such a density of
 objects per paragraph.

Yes, it is indeed a contrived example. I originally thought I had a use
for it --- i.e., analyzing the packages I had installed --- but soon
realized that such a task is better accomplished in a separate text
file.

 Also, cache cannot help here, because each time you edit a paragraph,
 all objects within are removed from the cache (because, AFAIK, there
 is no way to know if the edition altered a previously parsed object or
 not, so, as a security measure, all of them are wiped out) and you
 have to parse them again.

 Therefore, navigation should be fast but editing (with flyspell-mode
 enabled) is going to be slow.

Good to know.
Thanks again!

Could you update and try again? Parser's cache was inadvertently
disabled. I re-enabled it.

 I open a test.org file containing the following.

 * A headline * Arch packages * Another headline

 After opening a line under Arch Packages I call...

 C-u M-! pacman -Ss [RET]

 (Of course, this only works with archlinux.) This inserts a long list of
 packages that look like this:

 core/acl 2.2.52-2 [installed]
 Access control list utilities, libraries and headers
 core/archlinux-keyring 20140220-1 [installed]
 Arch Linux PGP keyring
 core/attr 2.4.47-1 [installed]
 Extended attribute support library for ACL support
 core/autoconf 2.69-1 (base-devel) [installed]
 A GNU tool for automatically configuring source code
 core/automake 1.14.1-1 (base-devel) [installed]
 A GNU tool for automatically creating Makefiles
  
 All in all, it's 12680 lines 

Note that it is a contrived example: the whole buffer is a single
paragraph containing around 150 objects. The current algorithm for
`org-element-context' is clearly not on par with such a density of
objects per paragraph.

Also, cache cannot help here, because each time you edit a paragraph,
all objects within are removed from the cache (because, AFAIK, there is
no way to know if the edition altered a previously parsed object or not,
so, as a security measure, all of them are wiped out) and you have to
parse them again.

Therefore, navigation should be fast but editing (with flyspell-mode
enabled) is going to be slow.

 But this works (more or less) with other very large chunks of text.
 E.g.,

 C-u M-! w3m -dump 
 http://www.gnu.org/software/emacs/manual/html_mono/emacs.html

This one should be reasonably fast in both cases.

 Is it possible to speed up org-element-context here?

Certainly. `org-element-context' is the less optimized part of the
parser code. There is room for improvements.

 For something called as often as org-mode-flyspell-verify, do we need
 all the overhead of the org-element parser?

Of course.

 Or would a hack optimized for speed (which is what the older version
 of org-mode-flyspell-verify represented) be enough?

IMO, the old version of this function was annoying as soon as you
switched to a non-english language. YMMV.

 I recall (though my memory may be faulty) discussions on the list
 quite some time back in which we decided to prioritize
 speed/efficiency over thoroughness/completeness in the checks run by
 org-mode-flyspell-verify.

Why prioritize when we can have both?

I agree that `org-mode-flyspell-verify' is not fast enough at the time
being, but it is quite usable anyway. Also, as a very demanding
function, it is a good benchmark for the parser.

In order to improve the current state, reports (like those in your
message) help a lot. You can also help improving the algorithms.

Thank you.

 Please do

That worked. Thank you.

 Tags are on commits, not on branches, and commmits can belong to
 multiple branches.

 Since the tagged commit is both on the maint and the master branch,
 make autoloads will use the same tag to generate Org's version in
 both case.

Ah, right. Oddly, I was pretty sure that some tags were identifying
master branch only, e.g, I can't remember seeing 8.2.5c on master.

 That is what I don't understand. You added 8.2.5h to maint, and
 master wasn't merged into maint since then. How can the tag
 propagate to master?

It doesn't.  But maint is included in master as an ancestor and git
describe uses the most recent tag in common ancestry to label a commit
from.  You can add the option --first-parent to only check tags in the
current branch.

I use org-mode version release_8.0.2-101-gce5988 (I follow the git

It doesn't happen with:

I had forgotten to rerun make after I pulled the latest version.
`org-version' now returns 8.2.5h.

And you're right, it doesn't happen when `org-element-use-cache' is set
to nil.

However, when `org-element-use-cache' is set to t, then it looks like
`org-element-context' uses the link's title instead of the link's value.
e.g.
#+BEGIN_EXAMPLE
  v-- with the cursor here, it returns (link (:type file :path foo ...))
[[file:foo][file:test 1 2 3]]
   ^-^
when the cursor is in this zone, it returns (link (:type file :path 
test ...))
  ^-- when the cursor is after this point (after the
  first space) it returns (link (:type file :path test 1 
2 3 ...))
#+END_EXAMPLE

[O] org-element-context doesn't parse consistently link with spaces

Hi Nicolas

With today's release_8.2.5h-676-gfb8a042 and C-c C-t on the todo
below, the last headline gets corrupted. Only when cache is enabled.

Hi Michael and Nicolas,

I suspect this is related the bug I reported earlier today:

http://permalink.gmane.org/gmane.emacs.orgmode/82979

I had not realized it had to do with org-element-cache. I can confirm
that setting org-element-cache to nil solves the problem.

Matt

I guess the same bug. I have overseen your report.

Re: [O] org-element-map no-recursion argument?

[Nicolas Goaziou]

Hello,

James Harkins jamshar...@gmail.com writes:

 I've written some emacs-lisp using org-element-map to iterate over
 source code blocks in an org buffer and insert them into another
 buffer, including a listing number and caption (so it's different from
 tangling).

 I was just trying to tweak it to ignore source code blocks in
 a comment section.

 More specifically -- I had moved some material into a Removed
 subtree (with a tag noexport). This subtree contains some source
 blocks, but I want my function to ignore these.

 I thought I could wrap the entire Removed section in
 #+begin/end_comment, and then tell org-element-map to skip comment
 blocks for recursion.

 (org-element-map tree 'src-block (lambda (element) ...)
  nil nil 'comment)

 But this has no effect. I guess the src-block filter erases the
 distinction between live and commented sections.

 I can work around it by commenting out the captions, but it would be
 nicer to have an entire off-limits section of the document.

This is a reasonable request, indeed.

One (backward compatible) solution could be to extend possible values
for NO-RECURSION argument, and allow functions on one argument (the
current element) in addition to symbols.

When the NO-RECURSION function returns a non-nil value for a given
element, the main function from `org-element-map' is applied to the
element, but not to its contents.


What do you think?

[O] org-element, spurious command??

[Robert Klein]

Hi,

I've been reading lisp/org-element.el, when I found a command lounging
around in the middle of the file outside of any defun:

(put 'org-element-map 'lisp-indent-function 2)

on line 4275 (maint tree this morning).

Is this intended to be there?


PS: it is also in the master tree, line 4276.

Thanks and best regards
Robert

Yes, it is. `org-element-map' is defined just above. This sexp sets
indentations rules for it.

 This works fine.  Now when I come back to this buffer I want to check

   (if (org-element-property (car prop) (org-element-at-point))
(setq hasprops t))
   (if (hasprops)

 However this doesn't work because (1) the car of prop (which is in
 fact the property name) is not necessarily capitalized and

 Then `upcase' the property name first. I assume you will only refer to
 user-defined properties so their equivalent keyword will always be in
 upper cases.

 (2) the property parameter of org-element-property is not a string,
 but a keyword symbol. Somehow I have to turn my string into the
 appropriate keyword symbol. Does anyone know how to do this?

 Use `intern'.

 For efficiency reasons, I also suggest to store `org-element-at-point'
 in a variable instead of computing it again each time you are looking
 for a property:

   (let ((hashprops nil)
 (element (org-element-at-point)))
 (dolist (prop org-writers-room-properties)
   (if (org-element-property (intern (concat : (upcase prop))) element)
   ...)))

ah, thank you so much for this. I don't know how I would ever have
found intern on my own.  makes my life much easier!

[O] org-element-property syntax (turning strings into keyword symbols)

[Matt Price]

Hi,

I'm trying to write a query that will check to see if the current
element has any of several properties set; the properties are defined
in a defcustom so I don't know in advance which properties I'm
interested in.  So I have the following code which INSERTS properties:

(defcustom org-writers-room-properties '((Synopsis . Put a short
summary here) (Role in Book . Describe what you want this section
to accomplish) (Characters . who is in this section))
  alist of properties to be inserted automatically on heading creation
  :group 'org-writers-room
  :type 'alist)

(defun org-wr-main-heading-hook ()
  Adds a properties drawer  populates it with several properties.
Intended to be used with org-insert-heading-hook, but is also
interactive.
  (interactive)
  (save-excursion
(dolist (this-property org-writers-room-properties)
  (org-set-property (car this-property) (cdr this-property))
)
(org-flag-drawer 'nil)
(select-window (window-with-name guide))
(org-cycle-hide-drawers 'all)
)
  )

This works fine.  Now when I come back to this buffer I want to check
whether any of the properties are actually there.  So I am trying
something like this:

(let ((hasprops nil))
  (dolist prop org-writers-room-properties
  (if (org-element-property (car prop) (org-element-at-point))
   (setq hasprops t))
  (if (hasprops)
  (etc.))

However this doesn't work because (1) the car of prop (which is in
