Version 7.02

Incompatible Changes

Code block hashes

Due to changes in the code resolving code block header arguments hashing of code block results should now re-run a code block when an argument to the code block has changed. As a result of this change all code blocks with cached results will be re-run after upgrading to the latest version.

Testing update

Anyone using the org-mode test suite will need to update the jump repository for test navigation by executing the following from the root of the org-mode repository.

git submodule update

Failure to update this repository will cause loading of org-test.el to throw errors.

Details

Fontify code in code blocks.

Source code in code blocks can now be fontified. Please customize the varable org-src-fontify-natively. For very large blocks (several hundreds of lines) there can be delays in editing such fontified blocks, in which case C-c ' should be used to bring up a dedicated edit buffer.

Thanks to Dan Davison for this.

Language-mode commands are available in the Org-buffer

The most general machinery for doing this is the macro `org-babel-do-in-edit-buffer'. There is also the convenience function `org-babel-do-key-sequence-in-edit-buffer' which makes use of this macro, and is bound to C-c C-v C-x and C-c C-v x. If there is an active region contained within the code block, then this is inherited by the edit buffer. Some examples of the sorts of usage this permits are

C-c C-v C-x M-; comment region according to language C-c C-v C-x C-M-\ indent region according to language

Users can make these more convenient, e.g.

(defun my/org-comment-dwim (&optional arg) (interactive "P") (or (org-babel-do-key-sequence-in-edit-buffer "\M-;") (comment-dwim arg)))

(define-key org-mode-map "\M-;" 'my/org-comment-dwim)

A common instance of this general pattern is built in to Org-mode, controlled by the variable `org-src-tab-acts-natively': if this variable is set, then TAB in a code block has the effect that it would have in the language major mode buffer.

Org-babel commands are available in language-mode edit buffer

Mirroring the language-native commands in Org buffers above, a new macro `org-src-do-at-code-block' and convenience function `org-src-do-key-sequence-at-code-block' provide the converse. When used in a language major-mode edit buffer (i.e. a buffer generated by C-c '), `org-src-do-key-sequence-at-code-block' executes a key sequence at the code block in the source Org buffer. The command bound to the key sequence in the Org-babel key map is executed remotely with point temporarily at the start of the code block in the Org buffer.

The command is not bound to a key by default, to avoid conflicts with language major mode bindings. To bind it to C-c @ in all language major modes, you could use

(add-hook 'org-src-mode-hook (lambda () (define-key org-src-mode-map "\C-c@" 'org-src-do-key-sequence-at-code-block)))

In that case, for example, C-c @ t issued in code edit buffers would tangle the current Org code block, C-c @ e would execute the block and C-c @ h would display the other available Org-babel commands.

Multi-line header arguments to code blocks

Code block header arguments can now span multiple lines using the new #+header: or #+headers: lines preceding a code block or nested in between the name and body of a named code block. Examples are given below.

  • multi-line header arguments on an un-named code block

    #+headers: :var data1=1
#+begin_src emacs-lisp :var data2=2
  (message "data1:%S, data2:%S" data1 data2)
#+end_src

#+results:
: data1:1, data2:2

  • multi-line header arguments on a named code block

      #+source: named-block
  #+header: :var data=2
  #+begin_src emacs-lisp
    (message "data:%S" data)
  #+end_src

  #+results: named-block
  : data:2

Unified handling of variable expansion for code blocks

The code used to resolve variable references in code block header arguments has now been consolidated. This both simplifies the code base (especially the language-specific files), and ensures that the arguments to a code block will not be evaluated multiple times. This change should not be externally visible to the Org-mode user.

Improved Caching

Code block caches now notice if the value of a variable argument to the code block has changed, if this is the case the cache is invalidated and the code block is re-run. The following example can provide intuition for the new behavior.

  #+srcname: random
  #+begin_src R :cache yes
  ,runif(1)
  #+end_src
  
  #+results[a2a72cd647ad44515fab62e144796432793d68e1]: random
  ,: 0.4659510825295
  
  #+srcname: caller
  #+begin_src emacs-lisp :var x=random :cache yes
  ,x
  #+end_src
  
  #+results[bec9c8724e397d5df3b696502df3ed7892fc4f5f]: caller
  ,: 0.254227238707244

Added :headers header argument for LaTeX code blocks

This makes it possible to set LaTeX options which must take place in the document pre-amble for LaTeX code blocks. This header argument accepts either a single string or a list, e.g.

  #+begin_src latex :headers \usepackage{lmodern} :file name1.pdf
  ,  latex body
  #+end_src
  
  #+begin_src latex :headers '("\\usepackage{mathpazo}" "\\usepackage{fullpage}") :file name2.pdf
  ,  latex body
  #+end_src

New function `org-export-string'

Allows exporting directly from a string to the specified export format.

Code block header argument ":noweb tangle"

Only expands <<noweb>> syntax references when tangling, not during export (weaving).

New function `org-babel-switch-to-session-with-code'

C-c C-v z (`org-babel-switch-to-session-with-code') is a variant of C-c C-v C-z (`org-babel-switch-to-session'): instead of switching to the session buffer, it splits the window between (a) the session buffer and (b) a language major-mode edit buffer for the code block in question. This can be convenient for using language major mode for interacting with the session buffer.

Improvements to R sessions

R now uses standard ESS code evaluation machinery in the :results value case, which avoids unnecessary output to the comint buffer. In addition, the R command responsible for writing the result to file is hidden from the user. Finally, the R code edit buffer generated by C-c ' is automatically linked to the ESS session if the current code block is using :session.

Temporary file directory

All babel temporary files are now kept in a single sub-directory in the /tmp directory and are cleaned up when Emacs exits.

Function for demarcating blocks `org-babel-demarcate-block'

Can be called to wrap the region in a block, or to split the block around point, bound to (C-c C-v d).

Function for marking code block contents `org-babel-mark-block'

Bound to C-M-h in the babel key map (i.e. C-c C-v C-M-h by default). This can be useful in conjunction with `org-babel-do-in-edit-buffer', for example for language-native commenting or indenting of the whole block.

Lists of anniversaries are now handeled better

When several anniversaries are defined in the bbdb anniversaries field (separated by semicolon), this is now handled nicely by the agenda.

Thanks to Lukasz Setmann for a patch to this effect.

Table fields are now aligned better, new <c> cookie.

In HTML export, table fields are now properly aligned in accord with automatic alignment in org, or as set by the <r>, <l>, and <c> cookies. The <c> cookie is new and has no effect in Org, but it does do the right thing in HTML export. A LaTeX export implementation will follow, but is currently still missing.

Update freemind converter to include body text

The freemind exporter now incorporates body text into the mind map.

Thanks to Lennard Borgman for this patch.

Make footnotes work correctly in message-mode

The footnotes code now searches for message-signature-separator (which is "– " by default) in order to place footnotes before the signature. Thanks to Tassilo Horn for this patch.

Improve XEmacs compatibility

Org-mode 7.02 now runs again in 21.4.22 if the new XEmacs base package is installed.

Thanks to Uwe Bauer, Volker Ziegler, Michael Sperber and others for a discussion that lead to this nice result.

Make it configurable wether agenda jumping prefers the future

When jumping to a date from the agenda using the j key, you may or may not like the property of Org's date reader to prefer the future when you enter incomplete dates. This can now be configured using the variable =org-agenda-jump-prefer-future'.

Add publishing functions for ASCII, Latin-1 and UTF-8

There are now publishing functions org-publish-org-to-ascii, org-publish-org-to-latin1, and org-publish-org-to-utf8.

Thanks to Matthias Danzl for showing how to do this.

Indentation and headline insertion after inline tasks

Indentation in inline tasks, and headline insertion after inline tasks now behave as expected.

Encryption in MobileOrg finally works

As soon as MobilOrg 1.5 hits the Apple's AppStore, you can encrypt your org files on public servers. Please see the documentation of MobileOrg and Appendix B of the manual for more details.

MobileOrg: Do not force to insert IDs

If you dislike the property of MobileOrg to insert ID properties for in all entries being part of an agenda view, you can now turn this off using the variable org-mobile-force-id-on-agenda-items. When this variable is set to nil, MobileOrg will use outline paths to identify entries. Note that this may fail if several entries have identical outline paths.

LaTeX minted package for fontified source code export

Patch by Dan Davison.

A non-nil value of `org-export-latex-minted' means to export source code using the minted package, which will fontify source code with color. If you want to use this, you need to make LaTeX use the minted package. Add minted to `org-export-latex-packages-alist', for example using customize, or with something like

(require 'org-latex) (add-to-list 'org-export-latex-packages-alist '("" "minted"))

In addition, it is neccessary to install pygments (http://pygments.org), and to configure `org-latex-to-pdf-process' so that the -shell-escape option is passed to pdflatex.

Allow to use texi2dvi or rubber for processing LaTeX to pdf

Please see the variable org-export-latex-to-pdf-process for more information.

Thanks to Olivier Schwander for the rubber part.

New STARTUP keywords to turn on inline images

If you want to inline images whenever you visit an Org file, use

#+STARTUP: inlineimages

Support for user-extensible speed commands.

There is a new hook org-speed-command-hook. Thanks to Jambunathan for a patch to this effect.

Add macro to insert property values into exported text

you can use {{{property{NAME}}}} to insert the value of a property upon export.

Thanks to David Maus for a patch to this effect.

LaTeX package fixes

We updated the list of default packages loaded by LaTeX exported files.

Allow "#" and "%" in tags

Tags can now also contain the characters # and %, in addition to @ and letters.

Show command names in manual

Andreas Röhler is adding command names to keys in the manual. This will take a while to complete, but a start has been made.

Make backslash escape "-" in property matches

When entering a tags/property query, "-" is a logical operator. However, "-" is also allowed in property names. So you can now write "SOME\-NAME" to work around this issue.

This was a request by Ilya Shlyakhter.

Document quick insertion of empty structural elements

Org-mode has a built-in template mechanism for inserting block templates. This was undocumented until now.

Thanks to Jambunathan K for the patch.

Implement MathJax support

Org-mode now uses MathJax to display math on web pages. We serve MathJax from the orgmode.org server, at least for the time being (thanks Bastien!). If you are going to use this for pages which are viewed often, please install MathJax on your own webserver.

To return to the old way of creating images and inserting them into web pages, you would have to set

(setq org-export-with-LaTeX-fragments 'dvipng)

or on a per-file basis

#+OPTIONS: LaTeX:dvipng

Agenda: Allow compact two-column display in agenda dispatcher

If you have many custom agenda commands, you can have the display in the dispatcher use two columns with the following settings

(setq org-agenda-menu-show-match nil
      org-agenda-menu-two-column t)

This was a request by John Wiegley.

Add org-wikinodes.el as a contributed package

One frequent request has been to be able to use CamelCase words for automatic cross links in a Wiki created by Org. THis is now possible with org-wikinodes.el, which is available in the contrib directory. We also have some documentation for this feature up on Worg.

Timer/clock enhancements

org-timer-set-timer displays a countdown timer in the modeline. From the agenda, `J' invokes org-agenda-clock-goto.

Version 7.01

Incompatible Changes

Emacs 21 support has been dropped

Do not use Org mode 7.xx with Emacs 21, use version 6.36c instead.

XEmacs support requires the XEmacs development version

To use Org mode 7.xx with XEmacs, you need to run the developer version of XEmacs. I was about to drop XEmacs support entirely, but Michael Sperber stepped in and made changes to XEmacs that made it easier to keep the support. Thanks to Michael for this last-minute save. I had hoped to be able to remove xemacs/noutline.el from release 7 by moving it into XEmacs, but this is not yet done.

Org-babel configuration changes

Babel took the integration into Org-mode as an opportunity to do some much needed house cleaning. Most importantly we have simplified the enabling of language support, and cleared out unnecessary configuration variables – which is great unless you already have a working configuration under the old model.

The most important changes regard the location and enabling of Babel (both core functionality and language specific support).

Babel

Babel is now part of the core of Org-mode, so it is now loaded along with the rest of Org-mode. That means that there is no configuration required to enable the main Babel functionality. For current users, this means that statements like

  (require 'org-babel)

or

  (require 'org-babel-init)

that may by lying around in your configuration must now be removed.

load path
Babel (including all language specific files – aside from those which are located in the contrib/ directory for reasons of licencing) now lives in the base of the Org-mode lisp directory, so no additional directories need to be added to your load path to use babel. For Babel users this means that statements adding babel-specific directories to your load-path should now be removed from your config.
language support

It is no longer necessary to require language specific support on a language-by-language basis. Specific language support should now be managed through the `org-babel-load-languages' variable. This variable can be customized using the Emacs customization interface, or through the addition of something like the following to your configuration (note: any language not mentioned will not be enabled, aside from emacs-lisp which is enabled by default)

  (org-babel-do-load-languages
   'org-babel-load-languages
   '((R . t)
     (ditaa . t)
     (dot . t)
     (emacs-lisp . t)
     (gnuplot . t)
     (haskell . nil)
     (ocaml . nil)
     (python . t)
     (ruby . t)
     (screen . nil)
     (sh . t)
     (sql . nil)
     (sqlite . t)))

Despite this change it is still possible to add language support through the use of require statements, however to conform to Emacs file-name regulations all Babel language files have changed prefix from org-babel-* to ob-*, so the require lines must also change e.g.

   (require 'org-babel-R)

should be changed to

   (require 'ob-R)

We have eliminated the org-babel-tangle-w-comments variable as well as the two main internal lists of languages, namely

  • org-babel-interpreters and
  • org-babel-tangle-langs

so any config lines which mention those variables, can/should be stripped out in their entirety. This includes any calls to the org-babel-add-interpreter function, whose sole purpose was to add languages to the org-babel-interpreters variable.

With those calls stripped out, we may still in some cases want to associate a file name extension with certain languages, for example we want all of our emacs-lisp files to end in a .el, we can do this will the org-babel-tangle-lang-exts variable. In general you shouldn't need to touch this as it already has defaults for most common languages, and if a language is not present in org-babel-tangle-langs, then babel will just use the language name, so for example a file of c code will have a .c extension by default, shell-scripts (identified with sh) will have a .sh extension etc…

The configuration of shebang lines now lives in header arguments. So the shebang for a single file can be set at the code block level, e.g.

  #+begin_src clojure :shebang #!/usr/bin/env clj
  ,  (println "with a shebang line, I can be run as a script!")
  #+end_src

Note that whenever a file is tangled which includes a shebang line, Babel will make the file executable, so there is good reason to only add shebangs at the source-code block level. However if you're sure that you want all of your code in some language (say shell scripts) to tangle out with shebang lines, then you can customize the default header arguments for that language, e.g.

  ;; ensure this variable is defined defined
  (unless (boundp 'org-babel-default-header-args:sh)
    (setq org-babel-default-header-args:sh '()))
  
  ;; add a default shebang header argument
  (add-to-list 'org-babel-default-header-args:sh
               '(:shebang . "#!/bin/bash"))

The final important change included in this release is the addition of new security measures into Babel. These measures are in place to protect users from the accidental or uninformed execution of code. Along these lines every execution of a code block will now require an explicit confirmation from the user. These confirmations can be stifled through customization of the `org-confirm-babel-evaluate' variable, e.g.

  ;; I don't want to be prompted on every code block evaluation
  (setq org-confirm-babel-evaluate nil)

In addition, it is now possible to remove code block evaluation form the C-c C-c keybinding. This can be done by setting the org-babel-no-eval-on-ctrl-c-ctrl-c variable to a non-nil value, e.g.

  ;; I don't want to execute code blocks with C-c C-c
  (setq org-babel-no-eval-on-ctrl-c-ctrl-c t)

An additional keybinding has been added for code block evaluation, namely C-c C-v e.

Whew! that seems like a lot of effort for a simplification of configuration.

New keys for TODO sparse trees

The key C-c C-v is now reserved for Org Babel action. TODO sparse trees can still be made with C-c / t (all not-done states) and C-c / T (specific states).

Customizable variable changes for DocBook exporter

To make it more flexible for users to provide DocBook exporter related commands, we start to use format-spec to format the commands in this release. If you use DocBook exporter and use it to export Org files to PDF and/or FO format, the settings of the following two customizable variables need to be changed:

  • org-export-docbook-xslt-proc-command
  • org-export-docbook-xsl-fo-proc-command

Instead of using %s in the format control string for all arguments, now we use three different format spec characters:

  • %i: input file argument
  • %o: output file argument
  • %s: XSLT stylesheet argument

For example, if you set org-export-docbook-xslt-proc-command to

java com.icl.saxon.StyleSheet -o %s %s /path/to/docbook.xsl

in the past, now you need to change it to

java com.icl.saxon.StyleSheet -o %o %i %s

and set a new customizable variable called org-export-docbook-xslt-stylesheet to /path/to/docbook.xsl.

Please check the documentation of these two variables for more details and other examples.

Along with the introduction of variable org-export-docbook-xslt-stylesheet, we also added a new in-buffer setting called #+XSLT:. You can use this setting to specify the XSLT stylesheet that you want to use on a per-file basis. This setting overrides org-export-docbook-xslt-stylesheet.

Details

Org Babel is now part of the Org core

See Org-babel configuration changes for instructions on how to update your babel configuration.

The most significant result of this change is that Babel now has documentation! It is part of Org-mode's documentation, see Chapter 14 Working With Source Code. The Babel keybindings are now listed in the refcard, and can be viewed from any Org-mode buffer by pressing C-c C-v h. In addition this integration has included a number of bug fixes, and a significant amount of internal code cleanup.

The default capture system for Org mode is now called org-capture

This replaces the earlier system org-remember. The manual only describes org-capture, but for people who prefer to continue to use org-remember, we keep a static copy of the former manual section chapter about remember.

The new system has a technically cleaner implementation and more possibilities for capturing different types of data. See Carsten's announcement for more details.

To switch over to the new system:

  1. Run 

    M-x org-capture-import-remember-templates RET

    to get a translated version of your remember templates into the new variable org-capture-templates. This will "mostly" work, but maybe not for all cases. At least it will give you a good place to modify your templates. After running this command, enter the customize buffer for this variable with 

    M-x customize-variable RET org-capture-templates RET

    and convince yourself that everything is OK. Then save the customization.

  2. Bind the command org-capture to a key, similar to what you did with org-remember:

    (define-key global-map "\C-cc" 'org-capture)

    If your fingers prefer C-c r, you can also use this key once you have decided to move over completely to the new implementation. During a test time, there is nothing wrong with using both system in parallel.

Implement pretty display of entities, sub-, and superscripts.

The command C-c C-x \ toggles the display of Org's special entities like \alpha as pretty unicode characters. Also, sub and superscripts are displayed in a pretty way (raised/lower display, in a smaller font). If you want to exclude sub- and superscripts, see the variable org-pretty-entities-include-sub-superscripts.

Thanks to Eric Schulte and Ulf Stegeman for making this possible.

Help system for finding entities

The new command M-x org-entities-help creates a structured buffer that lists all entities available in Org. Thanks to Ulf Stegeman for adding the necessary structure to the internal entity list.

New module to create Gantt charts

Christian Egli's org-taskjuggler.el module is now part of Org. He also wrote a tutorial for it.

Refile targets can now be cached

You can turn on caching of refile targets by setting the variable org-refile-use-cache. This should speed up refiling if you have many eligible targets in many files. If you need to update the cache because Org misses a newly created entry or still offers a deleted one, press C-0 C-c C-w.

Enhanced functionality of the clock resolver

Here are the new options for the clock resolver:

i/q/C-g  Ignore this question; the same as keeping all the idle time.

k/K      Keep X minutes of the idle time (default is all).  If this
         amount is less than the default, you will be clocked out
         that many minutes after the time that idling began, and then
         clocked back in at the present time.
g/G      Indicate that you \"got back\" X minutes ago.  This is quite
         different from 'k': it clocks you out from the beginning of
         the idle period and clock you back in X minutes ago.
s/S      Subtract the idle time from the current clock.  This is the
         same as keeping 0 minutes.
C        Cancel the open timer altogether.  It will be as though you
         never clocked in.
j/J      Jump to the current clock, to make manual adjustments.

For all these options, using uppercase makes your final state to be CLOCKED OUT. Thanks to John Wiegley for making these changes.

A property value of "nil" now means to unset a property

This can be useful in particular with property inheritance, if some upper level has the property, and some grandchild of it would like to have the default settings (i.e. not overruled by a property) back.

Thanks to Robert Goldman and Bernt Hansen for suggesting this change.

The problem with comment syntax has finally been fixed

Thanks to Leo who has been on a year-long quest to get this fixed and finally found the right way to do it.

Make it possible to protect hidden subtrees from being killed by C-k

This was a request by Scott Otterson. See the new variable org-ctrl-k-protect-subtree.

New module org-mac-link-grabber.el

This module allows to grab links to all kinds of applications on a mac. It is available in the contrib directory.

Thanks to Anthony Lander for this contribution.

LaTeX export: Implement table* environment for wide tables

Thanks to Chris Gray for a patch to this effect.

When cloning entries, remove or renew ID property

Thanks to David Maus for this change.

Version 6.36

Details

Inline display of linked images

Images can now be displayed inline. The key C-c C-x C-v does toggle the display of such images. Note that only image links that have no description part will be inlined.

Implement offsets for ordered lists

If you want to start an ordered plain list with a number different from 1, you can now do it like this:

1. [@start:12] will star a lit a number 12

Extensions to storing and opening links to Wanderlust messages

  • Remove filter conditions for messages in a filter folder If customization variable `org-wl-link-remove-filter' is non-nil, filter conditions are stripped of the folder name.
  • Create web links for messages in a Shimbun folder If customization variable `org-wl-shimbun-prefer-web-links' is non-nil, calling `org-store-link' on a Shimbun message creates a web link to the messages source, indicated in the Xref: header field.
  • Create web links for messages in a nntp folder If customization variable `org-wl-nntp-prefer-web-links' is non-nil, calling `org-store-link' on a nntp message creates a web link either to gmane.org if the group can be read trough gmane or to googlegroups otherwise. In both cases the message-id is used as reference.
  • Open links in namazu search folder If `org-wl-open' is called with one prefix, WL opens a namazu search folder for message's message-id using `org-wl-namazu-default-index' as search index. If this variable is nil or `org-wl-open' is called with two prefixes Org asks for the search index to use.

Thanks to David Maus for these changes.

Org-babel: code block body expansion for table and preview

In org-babel, code is "expanded" prior to evaluation. I.e. the code that is actually evaluated comprises the code block contents, augmented with the extra code which assigns the referenced data to variables. It is now possible to preview expanded contents, and also to expand code during during tangling. This expansion takes into account all header arguments, and variables.

A new key-binding C-c M-b p bound to `org-babel-expand-src-block' can be used from inside of a source code block to preview its expanded contents (which can be very useful for debugging). tangling

The expanded body can now be tangled, this includes variable values which may be the results of other source-code blocks, or stored in headline properties or tables. One possible use for this is to allow those using org-babel for their emacs initialization to store values (e.g. usernames, passwords, etc…) in headline properties or in tables.

Org-babel now supports three new header arguments, and new default behavior for handling horizontal lines in tables (hlines), column names, and rownames across all languages.

Version 6.35

Incompatible Changes

Changes to the intended use of org-export-latex-classes

So far this variable has been used to specify the complete header of the LaTeX document, including all the \usepackage calls necessary for the document. This setup makes it difficult to maintain the list of packages that Org itself would like to call, for example for the special symbol support it needs. Each time I have to add a package, I have to ask people to revise the configuration of this variable. In this release, I have tried to fix this.

First of all, you can opt out of this change in the following way: You can say: I want to have full control over headers, and I will take responsibility to include the packages Org needs. If that is what you want, add this to your configuration and skip the rest of this section (except maybe for the description of the [EXTRA] place holder):

  (setq org-export-latex-default-packages-alist nil
        org-export-latex-packages-alist nil)

Continue to read here if you want to go along with the modified setup.

There are now two variables that should be used to list the LaTeX packages that need to be included in all classes. The header definition in org-export-latex-classes should then not contain the corresponding \usepackage calls (see below).

The two new variables are:

org-export-latex-default-packages-alist
This is the variable where Org-mode itself puts the packages it needs. Normally you should not change this variable. The only reason to change it anyway is when one of these packages causes a conflict with another package you want to use. Then you can remove that packages and hope that you are not using Org-mode functionality that needs it.
org-export-latex-packages-alist
This is the variable where you can put the packages that you'd like to use across all classes. For example, I am putting amsmath and tikz here, because I always want to have them.

The sequence how these customizations will show up in the LaTeX document are:

  1. Header from org-export-latex-classes
  2. org-export-latex-default-packages-alist
  3. org-export-latex-packages-alist
  4. Buffer-specific things set with #+LaTeX_HEADER:

If you want more control about which segment is placed where, or if you want, for a specific class, have full control over the header and exclude some of the automatic building blocks, you can put the following macro-like place holders into the header:

[DEFAULT-PACKAGES]      \usepackage statements for default packages
[NO-DEFAULT-PACKAGES]   do not include any of the default packages
[PACKAGES]              \usepackage statements for packages 
[NO-PACKAGES]           do not include the packages
[EXTRA]                 the stuff from #+LaTeX_HEADER
[NO-EXTRA]              do not include #+LaTeX_HEADER stuff

If you have currently customized org-export-latex-classes, you should revise that customization and remove any package calls that are covered by org-export-latex-default-packages-alist. This applies to the following packages:

  • inputenc
  • fontenc
  • fixltx2e
  • graphicx
  • longtable
  • float
  • wrapfig
  • soul
  • t1enc
  • textcomp
  • marvosym
  • wasysym
  • latexsym
  • amssymb
  • hyperref

If one of these packages creates a conflict with another package you are using, you can remove it from org-export-latex-default-packages-alist. But then you risk that some of the advertised export features of Org will not work properly.

You can also consider moving packages that you use in all classes to org-export-latex-packages-alist. If necessary, put the place holders so that the packages get loaded in the right sequence. As said above, for backward compatibility, if you omit the place holders, all the variables will dump their content at the end of the header.

Damn, this has become more complex than I wanted it to be. I hope that in practice, this will not be complicated at all.

The constant org-html-entities is obsolete

Its content is now part of the new constant org-entities, which is defined in the file org-entities.el. org-html-entities was an internal variable, but it is possible that some users did write code using it - this is why I am mentioning it here.

Editing Convenience and Appearance

New faces for title, date, author and email address lines.

The keywords in these lines are now dimmed out, and the title is displayed in a larger font, and a special font is also used for author, date, and email information. This is implemented by the following new faces:

org-document-title org-document-info org-document-info-keyword

In addition, the variable org-hidden-keywords can be used to make the corresponding keywords disappear.

Thanks to Dan Davison for this feature.

Simpler way to specify faces for tags and todo keywords

The variables org-todo-keyword-faces, org-tag-faces, and org-priority-faces now accept simple color names as specifications. The colors will be used as either foreground or background color for the corresponding keyword. See also the variable org-faces-easy-properties, which governs which face property is affected by this setting.

This is really a great simplification for setting keyword faces. The change is based on an idea and patch by Ryan Thompson.

<N> in tables now means fixed width, not maximum width

Requested by Michael Brand.

Better level cycling function

TAB in an empty headline cycles the level of that headline through likely states. Ryan Thompson implemented an improved version of this function, which does not depend upon when exactly this command is used. Thanks to Ryan for this improvement.

Adaptive filling

For paragraph text, org-adaptive-fill-function did not handle the base case of regular text which needed to be filled. This is now fixed. Among other things, it allows email-style ">" comments to be filled correctly.

Thanks to Dan Hackney for this patch.

`org-reveal' (C-c C-r) also decrypts encrypted entries (org-crypt.el)

Thanks to Richard Riley for triggering this change.

Better automatic letter selection for TODO keywords

When all first letters of keywords have been used, Org now assigns more meaningful characters based on the keywords.

Thanks to Mikael Fornius for this patch.

Export

Much better handling of entities for LaTeX export

Special entities like \therefore and \alpha now know if they need to be in LaTeX math mode and are formatted accordingly.

Thanks to Ulf Stegemann for the tedious work to make this possible.

LaTeX export: Set coding system automatically

The coding system of the LaTeX class will now be set to the value corresponding to the buffer's file coding system. This happens if your setup sets up the file to have a line \usepackage[AUTO]{inputenc} (the default setup does this).

New exporters to Latin-1 and UTF-8

While Ulf Stegemann was going through the entities list to improve the LaTeX export, he had the great idea to provide representations for many of the entities in Latin-1, and for all of them in UTF-8. This means that we can now export files rich in special symbols to Latin-1 and to UTF-8 files. These new exporters can be reached with the commands C-c C-e n and C-c C-e u, respectively.

When there is no representation for a given symbol in the targeted coding system, you can choose to keep the TeX-macro-like representation, or to get an "explanatory" representation. For example, \simeq could be represented as "[approx. equal to]". Please use the variable org-entities-ascii-explanatory to state your preference.

Full label/reference support in HTML, Docbook, and LaTeX backends

#+LABEL definitions for tables and figures are now fully implemented in the LaTeX, Docbook, and HTML interfaces. \ref{xxx} is expanded to a valid link in all backends.

BEAMER export: Title of the outline frame is now customizable

The new option org-outline-frame-title allows to set the title for outline frames in Beamer presentations.

Patch by Lukasz Stelmach.

BEAMER export: fragile frames are better recognized

A lstlisting environment now also triggers the fragile option in a beamer frame, just like verbatim environments do.

Thanks to Eric Schulte for this patch.

BEAMER export: Protect <…> macro arguments

Macros for the BEAMER package can have arguments in angular brackets. These are now protected just like normal arguments.

Requested by Bill Jackson.

HTML export: Add class to outline containers using property

The HTML_CONTAINER_CLASS property can now be used to add a class name to the outline container of a node in HTML export.

New option org-export-email-info to turn off export of the email address

Default is actually off now.

Throw an error when creating an image from a LaTeX snippet fails

This behavior can be configured with the new option variable org-format-latex-signal-error.

Index generation

Org-mode can now produce a 2-level subject index spanning an entire publishing project. Write index entries in your files as

* What is org-mode?
#+index: Org-mode
#+index: Definitions!Org-mode

where the first line will produce an index entry Org-mode, while the second line will create Definitions with a sub-item Org-mode. Three-level entries are not supported.

To produce the index, set

:makeindex t

in the project definition in org-publish-project-alist. You may have to force re-export of all files to get the index by using a C-u prefix to the publishing command:

C-u M-x org-publish-all

Whenever an Org file is published in this project, a new file with the extension "orgx" will be written. It contains the index entries and corresponding jump target names. When all project files are published, Org will produce a new file "theindex.inc" containing the index as a to-level tree. This file can be included into any project file using

  #+include: "theindex.inc"

Org-mode will also create a file "theindex.org" with this include statement, and you can build a more complex structure (for example style definitions, top and home links, etc) around this statement. When this file already exists, it will not be overwritten by Org.

Thanks to Stefan Vollmar for initiating and driving this feature.

TODO Still need to do the LaTeX portion

MobileOrg

Encrypting stage files for MobileOrg

Since the use of (often pubic) servers is needed for MobileOrg, it is now possible to encrypt the files to be staged for MobileOrg. Version 1.2 of MobileOrg will be needed for this feature, and Richard Moreland will show instructions on his website once that is available. Basically, on the Org-side this will require the following settings:

  (setq org-mobile-use-encryption t
        org-mobile-encryption-password "My_MobileOrg_Password")

So the password will be visible in your local setup, but since the encryption is only for the public server, this seems acceptable.

Agenda

Specify entry types as an option

Custom Agenda commands can now limit the sets of entry types considered for this command by binding org-agenda-entry-types temporarily in the options section of the command. This can lead to significant speedups, because instead of laboriously finding entries and then rejecting them, a whole search cycle is skipped. For more information see the new section in Matt Lundin's agenda custom command tutorial.

Thanks to Matt Lundin for this feature.

Speed up multiple calls to org-diary by only doing buffer prep once

Also a patch by Matt Lundin.

Show and hide deadlines in the agenda

You can now hide all deadline entries in the agenda by pressing !.

Thanks to John Wiegley for this feature.

Agenda: Allow to suppress deadline warnings for entries also scheduled

The the docstring of the variable org-agenda-skip-deadline-prewarning-if-scheduled.

Expand file names in org-agenda-files (external file case)

If you are using a file to manage the list of agenda files, the names in this file can now contain environment variables and "~" to write them more compactly and portable.

Thanks to Mikael Fornius for a patch to this effect.

Agenda: Allow TODO conditions in the skip functions

The agenda skip function has now special support for skipping based on the TODO state. Here are just two examples, see the manual for more information.

(org-agenda-skip-entry-if 'todo '(\"TODO\" \"WAITING\"))
(org-agenda-skip-entry-if 'nottodo 'done)

Thanks to Lukasz Stelmach for this patch.

Extracting the time-of-day when adding diary entries

The time of day can now be extracted from new diary entries made from the agenda with (for example) i d. When org-agenda-insert-diary-extract-time is set, this is done, and the time is moved into the time stamp.

Thanks to Stephen Eglen for this feature.

The customization group org-font-lock has been renamed

The new name is `org-appearance'.

Thanks to Dan Davison for a patch to this effect.

The TODO list: Allow skipping scheduled or deadlined entries

Skipping TODO entries in the global TODO list based on whether they are scheduled or have a deadline can now be controlled in more detail. Please see the docstrings of org-agenda-todo-ignore-scheduled and org-agenda-todo-ignore-deadline.

Thanks to Lukasz Stelmach for patches to this effect.

Hyperlinks

Make org-store-link point to directory in a dired buffer

When, in a dired buffer, the cursor is not in a line listing a file, `org-store-link' will store a link to the directory.

Patch by Stephen Eglen.

Allow regexps in org-file-apps to capture link parameters

The way extension regexps in org-file-apps are handled has changed. Instead of matching against the file name, the regexps are now matched against the whole link, and you can use grouping to extract link parameters which you can then use in a command string to be executed.

For example, to allow linking to PDF files using the syntax file:/doc.pdf::<page number>, you can add the following entry to org-file-apps:

Extension: \.pdf::\([0-9]+\)\'
Command:   evince "%s" -p %1

Thanks to Jan Böcker for a patch to this effect.

Clocking

Show clock overruns in mode line

When clocking an item with a planned effort, overrunning the planned time is now made visible in the mode line, for example using the new face org-mode-line-clock-overrun, or by adding an extra string given by org-task-overrun-text.

Thanks to Richard Riley for a patch to this effect.

Tables

Repair the broken support for table.el tables again.

Tables created with the table.el package now finally work again in Org-mode. While you cannot edit the table directly in the buffer, you can use C-c ' to edit it nicely in a temporary buffer.

Export of these tables to HTML seem to work without problems. Export to LaTeX is imperfect. If fails if the table contains special characters that will be replaced by the exporter before formatting the table. The replacement operation changes the length of some lines, breaking the alignment of the table fields. Unfortunately this is not easy to fix. It is also not an option to not do these replacements. The table.el LaTeX exporter will for example not escape "&" in table fields, causing the exported tables to be broken.

Misc

New logging support for refiling

Whenever you refile an item, a time stamp and even a note can be added to this entry. For details, see the new option org-log-refile.

Thanks to Charles Cave for this idea.

New helper functions in org-table.el

There are new functions to access and write to a specific table field. This is for hackers, and maybe for the org-babel people.

org-table-get
org-table-put
org-table-current-line
org-table-goto-line

Tables: Field coordinates for formulas, and improved docs

Calc and Emacs-Lisp formulas for tables can access the current field coordinates with @# and $# for row and column, respectively. These can be useful in some formulas. For example, to sequentially number the fields in a column, use =@# as column equation.

One application is to copy a column from a different table. See the manual for details.

Thanks to Michael Brand for this feature.

Archiving: Allow to reverse order in target node

The new option org-archive-reversed-order allows to have archived entries inserted in a last-on-top fashion in the target node.

Requested by Tom.

Better documentation on calc accuracy in tables

Thanks to Michael Brand for this fix.

Clock reports can now include the running, incomplete clock

If you have a clock running, and the entry being clocked falls into the scope when creating a clock table, the time so far spent can be added to the total. This behavior depends on the setting of org-clock-report-include-clocking-task. The default is nil.

Thanks to Bernt Hansen for this useful addition.

American-style dates are now understood by org-read-date

So when you are prompted for a date, you can now answer like this

2/5/3         --> 2003-02-05
2/5           --> <CURRENT-YEAR>-02-05

org-timer.el now allows just one timer

There is now only a single free timer supported by org-timer.el. Thanks to Bastien for cleaning this up, after a bug report in this area by Frédéric Couchet.

Remember: Allow to file as sibling of current clock

C-3 C-c C-c will file the remember entry as a sibling of the last filed entry.

Patch by Lukasz Stelmach.

Org-reveal: Double prefix arg shows the entire subtree of the parent

This can help to get out of an inconsistent state produced for example by viewing from the agenda.

This was a request by Matt Lundin.

Add org-secretary.el by Juan Reyero to the contrib directory

org-secretary.el is a possible setup for group work using Org-mode.

Thanks to Juan Reyero for this contribution.

Babel

Eric and Dan have compiled the following list of changes in and around org-babel.

  • Added support for Matlab and Octave.
  • Added support for C and C++ code blocks.
  • Added support for the Oz programming language. Thanks to Torsten Anders for this contribution
  • Can now force literal interpretation of table cell contents with extra "$" in table formula. Thanks to Maurizio Vitale for this suggestion.
  • Variable references which look like lisp forms are now evaluated.
  • No longer adding extension during tangling when filename is provided. Thanks to Martin G. Skjæveland and Nicolas Girard for prompting this.
  • Added `org-babel-execute-hook' which runs after code block execution.

  • Working directories and remote execution

    This introduces a new header argument :dir. For the duration of source block execution, default-directory is set to the value of this header argument. Consequences include:

    • external interpreter processes run in that directory
    • new session processes run in that directory (but existing ones are unaffected)
    • relative paths for file output are relative to that directory

    The name of a directory on a remote machine may be specified with tramp syntax (/user@host:path), in which case the interpreter executable will be sought in tramp-remote-path, and if found will execute on the remote machine in the specified remote directory.

  • Tramp syntax can be used to tangle to remote files. Thanks to Maurizio Vitale and Rémi Vanicat.
  • org-R removed from contrib.
  • gnuplot can now return it's string output – when session is set to "none".
  • Now including source code block arguments w/source name on export.
  • Now able to reference file links as results.
  • Allow pdf/png generation directly from latex source blocks with :file header argument.

Version 6.34

Incompatible changes

Tags in org-agenda-auto-exclude-function must be lower case.

When defining an org-agenda-auto-exclude-function, you need to be aware that tag that is being passed into the function is always lower case - even if it was defined in upper case originally.

Details

Support for creating BEAMER presentations from Org-mode documents

Org-mode documents or subtrees can now be converted directly in to BEAMER presentation. Turning a tree into a simple presentations is straight forward, and there is also quite some support to make richer presentations as well. See the BEAMER section in the manual for more details.

Thanks to everyone who has contributed to the discussion about BEAMER support and how it should work. This was a great example for how this community can achieve a much better result than any individual could.

Hyperlinks

Add Paul Sexton's org-ctags.el

Targets like <<my target>> can now be found by Emacs' etag functionality, and Org-mode links can be used to to link to etags, also in non-Org-mode files. For details, see the file org-ctags.el.

This feature uses a new hook org-open-link-functions which will call function to do something special with text links.

Thanks to Paul Sexton for this contribution.

Add Jan Böcker's org-docview.el

This new module allows links to various file types using docview, where Emacs displays images of document pages. Docview link types can point to a specific page in a document, for example to page 131 of the Org-mode manual:

[[docview:~/.elisp/org/doc/org.pdf::131][Org-Mode Manual]]

Thanks to Jan Böcker for this contribution.

New link types that force special ways of opening the file
  • file+sys:/path/to/file will use the system to open the file, like double-clicking would.
  • file+emacs:/path/to/file will force opening the linked file with Emacs.

This was a request by John Wiegley.

Open all links in a node

When using C-c C-o on a headline to get a list of links in the entry, pressing RET will open all links. This allows something like projects to be defined, with a number of files that have to be opened by different applications.

This was a request by John Wiegley.

Agenda Views

Improve the logic of the search view.

The logic of search views is changed a bit. See the docstring of the function or-search-view.

These changes resulted from a discussion with Matt Lundin.

New face for entries from the Emacs diary

Entries that enter the Agenda through the Emacs diary now get the face org-agenda-diary.

This was a request by Thierry Volpiatto.

New function `org-diary-class' to schedule classes with skipped weeks.

This was a request by Daniel Martins.

Empty matcher means prompt in agenda custom commands

When an agenda custom command has an empty string as MATCH element, so far this would lead to a meaningless search using an empty matcher. Now an empty (or white) string will be interpreted just like a nil matcher, i.e. the user will be prompted for the match.

Agenda: Selectively remove some tags from agenda display

If you use tags very extensively, you might want to exclude some from being displayed in the agenda, in order to keep the display compact. See the new option org-agenda-hide-tags-regexp for details.

This was largely a patch by Martin Pohlack.

Export

Direct export of only the current subtree

Pressing 1 after C-c C-e and before the key that selects the export backend, only the current subtree will be exported, exactly as it you had selected it first with C-c @. So for example, C-c C-e 1 b will export the current subtree to HTML and open the result in the browser.

Direct export of enclosing node

Pressing SPC after C-c C-e and before the key that selects the export backend, the enclosing subree that is set up for subtree export will be exported, exactly as it you had selected it first with C-c @. So for example, C-c C-e SPC d will find the enclosing node with a LaTeX_CLASS property or an EXPORT_FILE_NAME property and export that.

Caching export images

Images that are created for example using LaTeX or ditaa for inclusion into exported files are now cached. This works by adding a hash to the image name, that reflects the source code and all relevant settings. So as long as the hash does not change, the image does not have to be made again. His can lead to a substantial reduction in export/publishing times.

Thanks to Eric Schulte for a patch to this effect.

Preserving line breaks for export no longer works

ASCII export always preserves them - no other export format does. We had attempted to use \obeylines for this in LaTeX, but that does create too many problems.

New symbols \EUR and \checkmark

\EUR symbols from Marvosym package, and \checkmark are now supported symbols in Org-mode, i.e. they will be exported properly to the various backends.

Allow LaTeX_CLASS_OPTIONS to set options, also from a property

You can set the options to the \documentclass command on a per-file basis, using

#+LaTeX_CLASS_OPTIONS: [11pt]

or on a per-tree basis using the corresponding property. The defined string will replace the default options entirely.

The encoding of LaTeX files is now handled property

Org now makes sure that the encoding used by the file created through the export mechanism is reflected correctly in the

\usepackage[CODINGSYSTEM]{inputenc}

command. So as long as the org-export-latex-classes definition contains an \usepackage[utf8]{inputenc} statement, that statement will be modified so that the correct option is used.

If you wan to use special encodings, for example utf8x instead of utf8, see the variable org-export-latex-inputenc-alist.

This was a request by Francesco Pizzolante.

Property API enhancements

Make a new special property BLOCKED, indicating if entry is blocked

A new special property BLOCKED returns "t" when the entry is blocked from switching the TODO state to a DONE state.

This was a request by John Wiegley.

New hooks for external support for allowed property values

It is now possible to hook into Org in order to provide the allowed values for any property with a lisp function. See the docstring of the variable org-property-allowed-value-functions

Allow unrestricted completion on properties

When listing the allowed values for a property, for example with a :name_ALL: property, completion on these values enforces that one of the values will be chosen. Now, if you add ":ETC" to the list of allowed values, it will be interpreted as a switch, and the completion will be non-restrictive, so you can also choose to type a new value.

Changes to Org-babel

  • The documentation for Org-babel has been drastically improved and is available on Worg at http://orgmode.org/worg/org-contrib/babel/
  • Source-code block names are now exported to HTML and LaTeX
  • Org-babel functions are now bound to keys behind a common key prefix (see http://orgmode.org/worg/org-contrib/babel/reference.php#sec-5)
  • Results are now foldable with TAB
  • Header argument values can now be lisp forms
  • Readable aliases for #+srcname: and #+resname:
  • Sha1 hash based caching of results in buffer
  • Can now index into variable values
  • org-babel-clojure now supports multiple named sessions

Miscellaneous changes

Make C-c r C customize remember templates

C-c r C is now a shortcut for

 M-x customize-variable RET org-remember-templates RET

This was a proposal by Adam Spiers.

Use John Gruber's regular expression for URL's

We now use a better regexp to spot plain links in text. This regexp is adopted from John Gruber's blogpost.

Thanks to William Henney for the pointer.

Implement tag completion of all tags in all agenda files

The new option org-complete-tags-always-offer-all-agenda-tags makes Org complete all tags from all agenda files if non-nil. Usually, setting it locally to t in org-remember buffers is the most useful application of this new feature.

Thanks to Tassilo Horn for a patch to this effect.

Version 6.33

Incompatible changes

Reorganize key bindings for archiving

The following keys now do archiving

C-c C-x C-a
archive using the command specified in org-archive-default-command. This variable is by default set to org-archive-subtree, which means arching to the archive file.

The three specific archiving commands are available through

C-c C-x C-s
archive to archive file
C-c C-x a
toggle the archive tag
C-c C-x A
move to archive sibling

These bindings work the same in an Org file, and in the agenda.

In addition:

  • In the agenda you can also use a to call the default archiving command, but you need to confirm the command with y so that this cannot easily happen by accident.
  • For backward compatibility, C-c $ in an org-mode file, and $ in the agenda buffer continue to archive to archive file.

Details

Level indentation cycling new empty entries and plain list items

To speed up data entry, TAB now behaves special in an empty headline, i.e. if the current line only contains the headline starter stars, maybe a TOD keyword, but no further content. This is usually the situation just after creating a new headline with M-RET or M-S-RET.

Then, TAB will first make the current entry a child of the entry above, then a parent, then a grand parent etc until it reaches top level. Yet another TAB and you will be back at the initial level at which the headline was created.

New plain list items behave in just the same way.

Sounds strange? Try it, it is insanely fast when entering data. If you still don't like it, turn it off by customizing org-cycle-level-after-item/entry-creation.

Thanks to Samuel Wales and John Wiegley for ideas that contributed to this new feature.

Speed commands at the start of a headline

If you set the variable org-use-speed-commands, the cursor position at the beginning of a headline (i.e. before the first star) becomes special. Single keys execute special commands in this place, for example outline navigation with f, b, n, and p, equivalent to the corresponding C-c C-f, C-c C-b, C-c C-n, and C-c C-f commands. The full list of commands can be seen by pressing ? at the special location. More commands can be added and existing ones modified by configuring the variable org-speed-commands-user.

This was a request by John Wiegley, based on similar speed navigation in allout.el.

Logging changes in scheduling and deadline time stamps

Setting the variables org-log-reschedule and org-log-redeadline to either time or note will arrange for recording a logbook entry whenever a scheduling date or deadline is changed.

This was a request by Rick Moynihan.

File remember notes into a date tree

Remember notes can now be filed to a location in a date tree. A date tree is an outline tree with years as top levels, months as level 2 headings, and days as level three headings. These are great for journals and for recording appointments and other loose dates because it will be easy to find all entries referencing a particular date, and it will be easy to archive all such entry from last year, for example.

To select date tree filing, set the HEADLINE part of the remember template to the symbol date-tree. The date tree will be build in the file on top level. However, if the file contains an entry with a non-nil DATE_TREE property, then the tree will be build under that headline.

New commands to create entries from agenda and calendar

If you make the variable org-agenda-diary-file point to an org-mode file, the i key in both the agenda buffer and in the Emacs calendar will be made to insert entries into that Org file. The dates at the cursor and the mark are being used when making entries for specific dates or blocks. In the new file, anniversaries will be collected under a special headline, and day/block entries will be filed into a date tree (see previous section).

This was a request by Stephen Eglen.

A new freemind exporter has been integrated with Org-mode

org-freemind.el has a number of entry points (for details, see the source code), but you can also use Org's C-c C-e m to export a file or a selected subtree.

Thanks to Lennart Borgman for this contribution. An earlier version of this file was part of the nxhtml package, under the name freemind.el.

Drawers are now exported properly

Drawers are now exported when the configuration requires it, i.e. if the variable `org-export-with-drawers' is t or a list containing the drawers to export.

Min/Max/Mean age operators in Column View.

This lets you see how much time has passed since the specified timestamp property each entry. The three operators (@min, @max, @mean) show either the age of the youngest or oldest entry or the average age of the children.

Thanks to James TD Smith for a patch to this effect.

Allow source code block indentation to be preserved

If org-src-preserve-indentation is non-nil, or if a block has a -i switch, then the behavior of org-exp-blocks is altered as follows:

  1. Indentation is not removed before passing the block contents to the block-transforming plugin.
  2. The result returned by the plugin is not re-indented.
  3. Editing the source code block with C-c ' preserves it's indentation.

Thanks to Dan Davison for this feature.

Frame/window control when switching to source code edit buffer.

When switching to a source code editing buffer with C-c ', you can now control the frame / window setup using the new variable org-src-window-setup.

Thanks to Dan Davison for this feature.

Refile an entry to the current clock

You can now quickly refile an entry to become a child of the entry currently being clocked. The keys for doing this are C-2 C-c C-w.

This was a request by Bernt Hansen.

Make C-c C-o open the attachment directory is there are no links

If there is no link in an entry, C-c C-o will now open the attachment directory instead.

This was a request/patch by John Wiegley.

org-mac-iCal.el: work with calendar "groups"

Some calendar systems (Google, Zimbra) handle subscriptions to multiple calendars (or to an account) by grouping them under a single caldav directory in the calendar tree. org-mac-iCal used to assumes there is only one ics file created per caldav directory, so while it creates all of the needed merged ics files, it only copies one of them to ~/Library/Calendar before importing the contents into the diary.

Thanks to Doug Hellmann for a patch to fix this.

New module org-learn.el in the contrib directory

The file implements the learning algorithm described at http://supermemo.com/english/ol/sm5.htm, which is a system for reading material according to "spaced repetition". See http://en.wikipedia.org/wiki/Spaced_repetition for more details.

Thanks to John Wiegley for this contribution.

New contributed package org-git-link.el

org-git-link.el defines two new link types. The git link type is meant to be used in the typical scenario and mimics the file link syntax as closely as possible. The gitbare link type exists mostly for debugging reasons, but also allows e.g. linking to files in a bare git repository for the experts.

Thanks to Raimar Finken for this contribution.

org-annotation-helper.el and org-browser-url.e. have been removed

Please switch to org-protocol.el, into which contains the same functionality in a more general framework.

The contributed org-export-freemind package has been removed.

Org now contains a new freemind exporter, org-freemind.el.

Org-babel Changes

  • Clojure is supported [Thanks to Joel Boehland]
  • Perl is supported
  • Ruby and Python now respond to the :file header argument
  • Added :results_switches header argument for passing switches through to raw src blocks
  • Preserve indentation in source blocks on export and tangle
  • Possible to evaluate noweb reference on tangling or code block evaluation
  • Allowing multiple noweb references on a single line
  • Cleaned up the passing of parameter values from Org-babel to language specific functions

Version 6.32

Rewrite of org-mobile.org, for MobileOrg 1.0 (build 20)

MobileOrg is currently under review at the iPhone App Store. You will need Org-mode version 6.32 to interact with it.

Added support for habit consistency tracking

org-habit.el contains new code to track habits. Please configure the variable org-modules to activate it. When active, habits (a special TODO entry) will be displayed in the agenda together with a "consistency graph". Habit tracking is described in a new manual section.

Thanks to John Wiegley for this contribution.

New context-aware tag auto-exclusion

After writing a function relating to location and context information, you will be able to press / RET in the agenda to exclude tasks that cannot be done in the current context. For details, see the information about filtering in the manual.

Thanks to John Wiegley for a patch to this effect.

New clock resolving tools

When clocking into a new task while no clock is running, Org now checks for orphaned CLOCK lines and offers to repair these before starting the clock. You can also configure this feature to check for idle time and prompt you to subtract that time from the running timer.

See the new manual section for more details.

Thanks to John Wiegley for a patch to this effect.

Mutually exclusive tag groups can now have a name in the tags interface

The customize interface allows to optionally add a string to the beginning or end of such a group.

Thanks to James TD Smith for a patch to this effect.

Agenda Search view: Search for substrings

The default in search view (C-c a s)is now that the search expression is searched for as a substring, i.e. the different words must occur in direct sequence, and it may be only part of a word. If you want to look for a number of separate keywords with Boolean logic, all words must be preceded by + or -.

This was, more-or-less, requested by John Wiegley.

Make space and backspace scroll the show window in the agenda

Pressing SPC again after using it to show an agenda item in another window will make the entire subtree visible, and show scroll it. Backspace and DEL will scroll back.

This was a request by Eric Fraga.

File tags are now offered for completion during a tag prompts

Requested by Matt Lundin.

Make `- SPC' an agenda filter that selects entries without any tags

Request by John Wiegley.

Better way to edit multi-line macro definitions

The editing tool key C-c ' now also edits #+MACRO definitions, including multiline macros.

Restructured Manual

The manual has been slightly reorganized. The archiving stuff, which was - somewhat obscurely - hidden in the Document Structure chapter, has been moved into the new chapter Capture-Refile-Archive. Also, there is a new chapter Markup which contains both the markup rules (moved there from the Export chapter) and the documentation for embedded LaTeX.

Improved figure placement in LaTeX and HTML export

Text can now be wrapped around figures. See the manual for details.

Allow date to be shifted into the future if time given is earlier than now

By setting

    (setq org-read-date-prefer-future 'time)

you indicate to Org that, if you only give a time at the date/time prompt, and if this time is earlier then the current time, then the date of tomorrow will be assumed to be valid for this event. A similar mechanism was already in place for dates, but now you can make it work for times as well.

Collected changes in org-babel

  • Source blocks can now reference source-blocks in other files using filepath:srcname syntax.
  • Inline code blocks like src_python{2+2} are now exported
  • Remote source block calls using the #+lob: srcname(arg=val) syntax can now be exported.
  • When :file is supplied with an R block, graphics are automatically sent to file and linked from the org buffer, thus appearing on export. The image format is obtained from the filename extension. Possible values are .png, .jpg, .jpeg, .tiff, .bmp, .pdf, .ps, .postscript, defaulting to png.
  • Results can be returned as parseable code using :results code, and as pretty-printed code using :results pp (emacs-lisp, python, ruby). Thanks to Benny Andresen for the idea and patch for emacs-lisp.
  • When :file filename is supplied, :exports file is unnecessary
  • Header args are taken from org-file-properties in addition to properties active in the subtree.
  • :noweb header argument now expands noweb references before source-block evaluation.
  • Tangling honours the new org variable org-src-preserve-indentation, so that correct code is output for a language like python that depends on indentation.

Changes in org-exp-blocks.el

  • Interblocks export has been simplified.
  • Support for R code (begin_R blocks and inline \R{}) has been removed. Please use org-babel instead.

Version 6.31

Org-babel is now part of the Org distribution

Org-babel provides the ability to execute source code in many different languages within org-mode documents. The results of code execution – text, tables and graphics – can be integrated into Org-mode documents and can be automatically updated during publishing. Since Org-babel allows execution of arbitrary code, the range of tasks that can be addressed from within an Org mode file becomes very large. Examples of ways in which Org-babel might be used include

  • Documenting a task that involves some programming so that it is automatically repeatable
  • Creating dynamic (executable) reports that respond to changes in the underlying data (Reproducible Research)
  • Exportation of code contained in an Org-mode document into regular source code files (Literate Programming)

Additionally, Org-babel provides a programming environment within Org files, in which data can be transmitted between parameterised source code blocks in different languages, as well as between source code blocks and Org-mode tables.

A simple API is defined so that users can add support for new "languages" (broadly construed). Languages currently supported are:

  • asymptote
  • css
  • ditaa
  • dot
  • emacs-lisp
  • gnuplot
  • haskell
  • ocaml
  • python
  • R
  • ruby
  • sass
  • sh
  • sql

Org-babel was designed and implemented Eric Schulte with continued significant help on both accounts from Dan Davison.

MobileOrg support

Richard Morelands iPhone/iPod Touch program MobileOrg can view Org files, mark entries as DONE, flag entries for later attention, and capture new entries on the road. Org-mode has now support to produce a staging area where MobileOrg can download its files, and to integrate changes done on the phone in a half automatic, half interactive way. See the new appendix B in the manual for more information.

Indented lines starting with "#+ " are treated as comments

To allow comments in plain lists without breaking the list structure, you can now have indented comment lines that start with "#+ ".

New STARTUP keyword `showeverything'

This will make even drawer contents visible upon startup. Requested by Jeff Kowalczyk.

New contributed package org-invoice.el

This package collects clocking information for billing customers.

Thanks to Peter Jones for this contribution.

Encrypting subtrees

org-crypt.el by John Wiegley and Peter Jones allows encryption of individual subtrees in Org-mode outlines. Thanks to John and Peter for this contribution.

Agenda: Support for including a link in the category string

The category (as specified by an #+CATEGORY line or CATEGORY property can contain a bracket link. While this sort-of worked in the past, it now is officially supported and should cause no problems in agenda display or update. The link can be followed by clicking on it, or with C-c C-o 0.

This was a request by Peter Westlake.

Version 6.30

Inconsistent changes

Agenda now uses f and b to move through time

Up to now, the Org-mode agenda used the cursor keys left and right to switch the agenda view forward an backward through time. However, many people found this confusing, and others wanted to be able to do cursor motion in the agenda, for example to select text. Therefore, after an extensive discussion on emacs-orgmode@gnu.org, it was decided to use the b and f keys instead, and to let the cursor keys do cursor motion again.

Agenda follow mode is now on the F key

This was necessary to free up the f key, see above.

Details

Maintenance

New command to submit a bug report

There is now a special command M-x org-submit-bug-report. This command will create a mail buffer with lots of useful details. In particular, it contains complete version information for Emacs and Org-mode. It will also (if you agree to it) contain all non-standard settings of org-mode and outline-mode related variables. Even if you do not sent your emails from within Emacs, please still use this command to generate the information and then copy it into your mail program.

The command will not generate and include a *Backtrace* buffer, please do this yourself if you have hit an error. For more information, see the feedback section of the manual.

New contributed package org-track.el

This package allows to keep up-to-date with current Org development, using only Emacs on-board means. So if you don't want or cannot use git, but still want to run the latest and hottest Org-mode, this is for you.

Thanks to Sebastian Rose for this contribution.

Agenda

Agenda now uses f and b to move through time

Up to now, the Org-mode agenda used the cursor keys left and right to switch the agenda view forward an backward through time. However, many people found this confusing, and others wanted to be able to do cursor motion in the agenda, for example to select text. Therefore, after an extensive discussion on emacs-orgmode@gnu.org, it was decided to use the b and f keys instead, and to let the cursor keys do cursor motion again.

Agenda follow mode is now on the F key

This was necessary to free up the f key, see above.

The agenda can be put into a dedicated frame

When the variable org-agenda-window-setup has the value other-frame, then the new frame created to show the agenda will now have the window marked as dedicated. As a consequence, exiting the agenda while the agenda is the only window on the frame will kill that frame.

This was a request by Henry Atting.

New mode to show some entry body text in the agenda

There is now a new agenda sub-mode called org-agenda-entry-text-mode. It is toggled with the E key. When active, all entries in the agenda will be accompanied by a few lines from the outline entry. The amount of text can be customized with the variable org-agenda-entry-text-maxlines.

This was a request by Anthony Fairchild, Manish, and others.

Improve following links from the agenda

C-c C-o in the agenda will now offer all links in the headline and text of an entry. If there is only a single link, it will be followed immediately.

Avoid some duplicate entries

There is a new variable that can be used to avoid some duplicate agenda entries: org-agenda-skip-scheduled-if-deadline-is-shown If that is set, it avoids that an entry shows up in the agenda for today for both a scheduling and a deadline entry. See the docstring of the variables for more details.

This partially addresses a request by Samuel Wales.

Mark the running clock in the agenda.

If the entry currently being clocked is present in the agenda, it will be highlighted with the face org-agenda-clocking.

This was a request by Rainer Stengele.

Export

Allow LaTeX export to use the listings package

The LaTeX listings package can now be used for formatting fontified source code in many programming languages. For more information, see http://thread.gmane.org/gmane.emacs.orgmode/16269 and http://orgmode.org/worg/org-faq.php#fontified_source_code_w_latex

Thanks to Eric Schulte for this patch.

Remove table rows that only contain width and alignment markers

The width and alignment in table columns can be set with a cookie like "<10>" or "<r>" or "<r10>". In order to keep Org from exporting such lines, the first column of a line should contain only "/". However, for convenience, there is now a special case: If the entire row contains only such markers, the line will automatically be discarded during export, even is the first column is not "/".

Allow Macro calls to span several lines.

Macro calls may now span several lines, to write several arguments in a cleaner way. The result of a macro call can also span several lines, by inserting the string "\n" (backslash followed by n) into the value in the macro definition.

These were requests by Stefan Vollmar.

Misc

Quick access to all links in an entry

If C-c C-o is called while the cursor is in a headline, but not directly on a link, then all links in the entry will be offered in a small menu. If there is only a single link, it will be followed without a prompt.

Visibility Cycling: Allow to show all empty lines after a headline

org-cycle-separator-lines can now be set to a negative value, to indicate that, if the number of empty lines before a visible entry is greater than the specified number, then all empty lines should be shown.

This was a request by "PT" whatever this means.

Allow language names to replace some strange major mode names

Sometimes a language uses a major mode which can't be guessed from it's name. There is now a new variable org-src-lang-modes which can be used to map language names to major modes when this is the case. This is used when editing a source-code block, or when exporting fontified source-code with htmlize.

Thanks to Eric Schulte for a patch to this effect.

iswitchb support for many completion prompts

This is enabled using org-completion-use-iswitchb, and follows the same model of usage as for ido users.

Thanks to John Wiegley for a patch to this effect.

New commands to set the effort property of an entry

There is now a special command, C-c C-x e to set the Effort property of an entry. From the agenda you can even use e. If you have set up allowed values for the Effort property, then using a prefix argument will directly select the nth allowed value. For example, in the agenda, 5 e will select the 5th allowed value.

This was a request by Michael Gilbert

Edit src works now better with killing buffer

Thanks to Dan Davison for a patch to this effect
