* lisp/org.el (org-open-at-point): Open "docview"-type links
correctly, i.e., without adding "file+" first.
(org-open-file-with-system, org-open-file-with-emacs): Change
signature. Deprecate functions.
* lisp/org-docview.el (org-docview-open): Open file even when no file
number is specified.
This change removes "file+emacs" and "file+sys" types from
`org-link-protocols', since they are not hard-coded in
`org-open-at-point'.
* org.el (org-emphasis-alist): Use `org-verbatim' for =text=
and `org-code' for ~text~.
* org.texi (Emphasis and monospace): Document the use of
=verbatim= and ~code~ to be consistent with
`org-element-text-markup-successor'.
Thanks to Yasushi for reporting this.
* lisp/org.el (org-open-at-point): White spaces after an object are
usually ignored by the function. Though, when point is right after
the object, still activate it.
* testing/lisp/test-org.el (test-org/custom-id): Fix test.
* lisp/org.el (org-open-at-point): On an unsupported object nested
within another object, try to open the parent object.
This should correctly open the following link, with point on the
verbatim object:
[[http://orgmode.org][=verbatim=]]
* lisp/org.el (org-open-at-point): Do not do anything when point is on
white spaces after an object.
* testing/lisp/test-org.el (test-org/custom-id): Modify test.
* lisp/org.el (org-open-at-point): Allow options when using
applications in links with options.
(org-open-file-with-system, org-open-file-with-emacs): Change
signature to be compatible with `org-open-file'
* lisp/org.el (org-open-at-point): Rewrite function using Element
parser.
(org-link-types): Add "help" type.
* testing/lisp/test-org-open-at-point.el: Remove file. Two tests are
not supported anymore (namely bracket-link-before and
plain-link-before) and the other tests are wrong (mixing id and
custom-id links).
* testing/examples/open-at-point.org: Remove file.
* testing/lisp/test-org.el (test-org/custom-id): Add test.
Unlike to the previous implementation, this one will only open links
under point or just before point, not links on the same line but
before point.
* lisp/org.el (org-link-escape-chars): Extend docstring.
(org-link-escape-chars-browser): Mention in docstring that it will
become a candidate for removal.
(org-link-escape-browser): Mention in docstring that it will become a
candidate for removal.
(org-open-at-point): Move `url-encode-url' and comments into
`org-link-escape-browser'.
* lisp/ox-html.el (org-html-link): Make use of
`org-link-escape-browser' like `org-open-at-point'.
* testing/lisp/test-org.el (test-org/org-link-escape-chars-browser):
Mention in docstring that it will become a candidate for removal.
* lisp/org.el (org-toggle-fixed-width): New function.
* testing/lisp/test-org.el (test-org/toggle-fixed-with): New test.
This replaces the old implementation removed in commit
6a00c96541.
* lisp/org.el (org-hide-macro-markers): new option
(org-fontify-macros): new function
(org-set-font-lock-defaults): call `org-fontify-macros'
* doc/org.texi: Document user option `org-hide-macro-markers'
TINYCHANGE
* org.el (org-provide-todo-statistics): Allow to set to a list
of two lists, one with TODO keywords, the other one with DONE
keywords.
(org-update-parent-todo-statistics): Correctly handle
`org-provide-todo-statistics' when it is set as a list of two
lists, for TODO and DONE keywords.
Thanks to Fletcher Charest for reporting this and requesting
this feature.
* org.el (org-insert-all-links): New parameters `pre' and
`post' to specify a string to preprend and append.
(org-insert-last-stored-link): New command.
(org-mode-map): Bind the new command to `C-c M-l'.
Thanks to Sébastien Vauban for requesting this and to Nick
Dokos for testing and fixing the patch.
* org.el (org-outline-overlay-data): Set the insertion-type of end
bound marker of the function to t (means marker advances when you
insert text at it)
This is to conserve outline visibility property when changes are made
at the end bound of the data.
For example: try `org-babel-execute-subtree' on a folded outline:
The new result will be shown after the folded part of the outline
whereas the outline body should not be visible.
TINYCHANGE
* org.el (org-demote): Ignore invisible text when aligning
tags.
(org-set-tags): When JUST-ALIGN is 'ignore-column, ignore
invisible text when restoring the cursor to the correct
column.
This fixes a bug about demoting hidden headlines.
If org-move-to-column temporarily ignore visibility
specs, this will prevent org-demote to work correctly
in hidden regions.
Thanks to Susan Cragin for reporting this bug.
* lisp/org.el (org-toggle-item): Do not call `org-list-struct' twice
and fix checkboxes after modifying one of them.
This patch is relative to 213c2a6aa0.
* lisp/org.el (org-match-substring-regexp): Simplify syntax when not
using braces. Also make the variable a defconst.
(org-match-substring-with-braces-regexp): Make the variable a defconst
and remove a useless group in regexp.
* lisp/org-element.el (org-element-subscript-parser,
org-element-superscript-parser): Adapt to group changes.
* lisp/org.el (org-get-previous-line-level): Do not call
`org-current-level' twice unless necessary. Also, avoid using
`line-number-at-pos' when the information needed is to know if point
is in the first line of the visible part of the buffer.
* org.el (org-refile-get-location): Check for a refile
position when the position is not nil, otherwise allow to
create the parent node if the user requests it.
Thanks to Li Zhuo for reporting this bug and for providing
a preliminary patch.
* org.el (org-shiftcontrolup, org-shiftcontroldown): When
`org-support-shift-select' is not `nil', let-bind it to nil
if point is on a clock log. Otherwise throw an error.
* org.el (org-do-emphasis-faces): Handle false positives by
restarting the re-search one char after the beginning of the
match, not one char before its ending.
Before this fix, consider this buffer
** Headline
- *Bold* non-bold
- *Bold* non-bold
The first false positive is "** Headline\n - *Bold*"
Starting the search again from the last "*" will skip
the "*Bold*" string. Starting again at "* Headline" will
find it.
* lisp/org.el (org-set-font-lock-defaults): use a shy regex for
identifying macros to fontify
Before this change, the xxx in the following text would be erroneously
fontified with the macro face:
{{{macro1()}}} xxx {{{macro2()}}}
* org.el (org-self-insert-command)
(orgtbl-self-insert-command): Change the value of the
`delete-selection' property to allow other commands like
`electric-pair-will-use-region' to be run before deletion.
Thanks to Harald Hanche-Olsen for reporting this.
* org.el (org-babel-do-in-edit-buffer): Declare.
(org-babel-load-file, org-insert-comment)
(org-comment-or-uncomment-region): Don't require 'ob-core.
(org-mode-map): Remap `comment-dwim' to `org-comment-dwim'.
(org-comment-dwim): New command.
* ob-core.el (org-babel-do-in-edit-buffer): Make an autoload.
See http://lists.gnu.org/archive/html/emacs-devel/2013-12/msg00154.html
for a discussion about this bug.
* lisp/org.el (org-ctrl-c-ctrl-c): When point is on an unsupported
object, look for something to do at a higher level instead of
bailing out.
For example, C-c C-c should toggle checkbox in the following example
even though X point is technically on a subscript.
- [ ] a_Xb
* lisp/org.el (org-mode-restart): Check for derived-mode-p instead of
"org-mode" exactly. This covers a situation normal-mode already
instantiates a derived mode (e.g. via file local variables).
* lisp/org.el (org-mode-restart): Call normal-mode,
instead of org-mode. This will set the mode but it
will also set file local variables properly.
Reported by Tom Dye: C-c C-c on e.g an #+OPTIONS line
would lose file local variable settings.
The original fix (commit 5ea0228) was incorrect: if the
local variable was a mode setting, then we ended up in an
"infinite" recursion. Problem found, reported and a reproducer
provided by York Zhao.
* lisp/org.el (org-mode-flyspell-verify): Rewrite function using
Org parser. As a consequence, Org is more cautious about areas
where checks are allowed.

subtler when removing flyspell overlays.
(org-unfontify-region): Remove reference to unused `org-no-flyspell'
property.
(org-fontify-drawers): New function.
(org-set-font-lock-defaults): Use new function to fontify drawers.
* contrib/lisp/org-wikinodes.el (org-wikinodes-activate-links): Remove
reference to unused `org-no-flyspell' property.
* lisp/org.el (org-entry-get): Widen buffer in order to retrieve
properties, as `org-entry-properties' and
`org-entry-get-with-inheritance' already do.
* lisp/org.el (org-entry-get): Widen buffer in order to retrieve
a property, as both `org-entry-properties' and
`org-entry-get-with-inheritance' already do.
* lisp/org.el (org-mode): Call `hack-local-variables'
at the end of `org-mode' to set file local variables.
Cribbed from `normal-mode'.
Reported by Tom Dye: C-c C-c on e.g an #+OPTIONS line
would lose file local variable settings.
* lisp/org.el (org-clock-string, org-closed-string)
(org-deadline-string, org-scheduled-string)

* lisp/ox.el: Move defsubst `org-export-get-parent´ before its many
uses.
* org-macs.el (org-autoload): Delete.

doc-view directly.

Thanks to François Pinard for suggesting this.
* lisp/org.el (org-insert-comment, org-comment-or-uncomment-region):
Use `org-element-at-point' instead of `org-in-src-block-p' to check
if we're within a source block.
* testing/lisp/test-org.el: Add test.
* lisp/org.el (org-set-tags): Width of strings presenting on a buffer
should be calculated with `string-width' instead of `length'.
This fixes unaligned tags for the languages with multi-width
characters.
TINYCHANGE
* org.el (org-sort-entries): Mention the
`org-after-sorting-entries-or-items-hook' hook in the
docstring.
Thanks to Andreas Röhler for suggesting this.
* lisp/org.el (org-insert-comment, org-comment-or-uncomment-region):
use the relevant language’s major mode comment function if called from
within a source block.
This patch makes it easier to (un)comment lines of babel source. Now
M-; in a soucre code block should Just Work.
The modification to ‘org-insert-comment’ also fixes a bug, whereby the
function would eat blank lines after it. The first block, where ! is
the point, would lead to the second instead of the third:
#+name: orig
#+begin_src org
xxxxxxx
!
yyyyyy
#+end_src
#+name: bad
#+begin_src org
xxxxxxx
#
yyyyyy
#+end_src
#+name: desired
#+begin_src org
xxxxxxx
#
yyyyyy
#+end_src
Also, the ‘org-comment-or-uncomment-region’ change results in an
undesirably move of the point after the comment is created. This is
because ‘comment-region’ wraps the call to ‘comment-region-function’
in a ‘save-excursion’. The org mode code deletes and reinserts the
whole babel block, which confuses save-excursion. Org carefully puts
the point back in the proper place, but comment-region’s
save-excursion then substitutes its own erroneous placement.
* org.el (org-babel-load-file): Set `exported-file' correctly,
in case the file as been tangled using a buffer-local value.
* ob-tangle.el (org-babel-tangle-file): Return the list of
tangled files.
Thanks to Sam Flint for reporting this.
* lisp/org.el (org-flag-drawer): Rewrite function using Elements.
Also prevents flagging drawers within example blocks.
* testing/lisp/test-org.el (test-org/flag-drawer): Add test.
* lisp/org.el (org-display-inline-images): Modify link regular
expression to match images in description part. Update doc string to
explain link behavior.
* lisp/org.el (org-insert-heading): Do not error out when inserting is
to be done at one of the buffer's boundaries.
* testing/lisp/test-org.el: Add tests.
* lisp/org.el (org-insert-todo-heading-respect-content): Pass correct
prefix arg to always insert heading.
TINYCHANGE
This function used a second argument t, which is eventually passed to
org-insert-heading, adding a list item when inside a plain list. Use
the proper argument '(4) now, to always create a heading, just like
the function's name and documentation imply.
* lisp/org.el (org-indent-region): BEGIN_SRC and END_SRC lines should
not be considered part of the source block for the purposes of
indentation.
TINYCHANGE
* lisp/org-element.el (org-element-center-block-parser,

org-element-verse-block-parser, org-element-special-block-parser,
org-element-example-block-parser, org-element-headline-parser,
org-element-inlinetask-parser): Remove :hiddenp property.
* lisp/org.el (org-end-of-line, org-down-element): Use an equivalent
of :hiddenp property.
* testing/lisp/test-org-element.el: Remove tests.
The property is removed because it is buggy (e.g., when there's a link
just after a block opening line) and not really useful.
* lisp/org.el (org-link-escape-chars): Add comment with escape numbers
alphabetically ordered.
(org-link-escape-chars-browser): Add comment with escape numbers.
(org-link-escape): Use better readable char constant instead of number
constant for percent char.
(org-link-escape-browser): New function to substitute duplicate source
code.
(org-open-at-point): Substitute duplicate source code.
* testing/README: Make comment in source code example clearer.
* testing/lisp/test-org.el (test-org/org-link-escape-chars-browser):
Change URL to real use case and use the new function
`org-link-escape-browser'.
* lisp/org.el (org-ctrl-c-ctrl-c): When using C-c C-c at an item with
point on a link, make sure checkbox, if any, is toggled.

* lisp/org.el (org-property-drawer-re): Make less greedy to avoid
overreaching matches.
(org-clock-drawer-re): Make less greedy to avoid

I suggest the following change so that C-u C-u C-c ! inserts an inactive
timestamp. I also document the INACTIVE argument of org-time-stamp.

Subject: [PATCH] Enforce the convention that C-c ! inserts inactive
timestamps.
* lisp/org.el (org-time-stamp): When INACTIVE is non-nil, insert an
inactive timestamp also with double universal argument.
* lisp/org.el (org-insert-heading): Improve whitespace behavior at
end of subtree.
In a subtree with lots of empty space at the end, until now the new
entry would be inserted after all that whitespace. Now, it is
inserted closer to the existing text, and the whitespace remains after
the new headline.
* doc/org.texi (@LaTeX{} specific attributes): Document that tabu
and tabularx packages are not in the default set of packages.
* lisp/org.el (org-latex-default-packages-alist): Add the `rotating'
package to the list of default packages. Improve docstring.
* lisp/org.el (org-insert-property-drawer): Insert only after space in
current line.
This fixed a bug reported by Mathieu Boespflug, who writes:

* lisp/org.el (org-meta-return): Allow M-RET to insert items within
drawers. Rewrite function.
This patch also allows a user to insert a headline within a drawer,
which will basically break it. The point is to leave user responsible
for his editing actions.
* lisp/org.el (org-overview): Preserve point.
We want to preserve point when changing global visibility. This is a
bit dangerouns, because it can leave point in an invisible location.
However, we want to make sure that pressing M-TAG three times returns
us to the same position as before.
* lisp/org.el (org-read-date-minibuffer-local-map): Don't replace disputed
keys when defining this keymap.
(org-read-date: Remove unnecessary binding of `org-replace-disputed-keys'.
This original fix did not work, thanks to Miro Bezjak for showing what
the proper fix should be.
* lisp/org.el (org-open-at-point): The new code is being run in the
same spot as `org-open-link-functions'. In case they failed, check
if link matches "^id:" and if so, load the id interface and follwo the
link.
This fixes Emacs bug#14910: org-mode `org-open-at-point' doesn't
follow id links.
* lisp/org.el (org-adaptive-fill-function): Do not handle
`adaptive-fill-regexp' in comments as the behaviour is not
satisfying.
* testing/lisp/test-org.el: Remove test.
* lisp/org.el (org-unlogged-message): New function.
(org-cycle): Use `org-unlogged-message'.
(org-cycle-internal-global): Use `org-unlogged-message'.
(org-cycle-internal-local): Use `org-unlogged-message'.
(org-global-cycle): Use `org-unlogged-message'.
(org-display-outline-path): Use `org-unlogged-message'.
* ox-latex.el (org-latex-item): Use square as unchecked symbol.
* org.el (org-latex-default-packages-alist): Remove latexsym.
Use amssymb symbols to reduce required packages.
* lisp/org.el (org-insert-heading): Improve the empty line insertion behavior.
Basically, never remove empty lines, only add them.
This was a request by Nicolas Goaziou.
* contrib/lisp/org-mac-link-grabber.el: File removed.
* contrib/lisp/org-mac-link.el: New file.
* contrib/lisp/org-mac-message.el: File removed
* lisp/org.el (org-modules): Update with the new module org-mac-link
Patch by Anthony Lander
* lisp/org.el (org-agenda-ignore-drawer-properties): New option
(org-agenda-prepare-buffers): Honour
`org-agenda-ignore-drawer-properties'.
Following a proposal by Daniel Clemente
* lisp/org.el (org-adaptive-fill-function): Look for a fill prefix at
the beginning of the paragraph and subsquently on its second line
instead of the current line.
* testing/lisp/test-org.el: Add test
* lisp/org.el (org-ctrl-c-ctrl-c): 'C-c C-c' on a link is usually a
no-op. If that link is in a headline, act as if the 'C-c C-c' was
called on the headline, not the link.
* lisp/org.el (org-bookmark-names-plist): New user option.
