The last data line in a table is often a line with important data, for
example sums of a column. In tables with varying length, the row
number of this line is constantly changing, which makes it hard to
write programs creating tables and then installing formulas.
This patch introduces @0 as a special reference to the last row, so
that @0$3 would be the field in the last row, 3rd column.
Unique identifiers for entries can now be used more efficiently.
Internally, a hash array has replaced the alist used so far to
keep track of the files in which an ID is defined. This makes it
quite fast to find an entry by ID.
There is now a new link type which looks like this:
id:GLOBALLY-UNIQUE-IDENTIFIER
This link points to a specific entry. When you move the entry to
a different file, for example if you move it to an archive
file, this link will continue to work.
The file /org-id.el/ contains an API that can be used to write
code using these identifiers, including creating IDs and finding
them wherever they are.
Org has its own method to create unique identifiers, but if the
system has /uuidgen/ command installed (Mac's and Linux systems
generally do), it will be used by default. You an also select
the method by hand, using the variable =org-id-method=.
If the ID system ever gets confused about where a certain ID is,
it initiates a global scan of all agenda files with associated
archives, all files previously known containing any IDs, and all
currently visited Org-mode files to rebuild the hash. You can
also initiate this by hand: =M-x org-id-update-id-locations=.
Running this command will also dump into the =*Messages*= buffer
information about any duplicate IDs. These should not exist, but
if you /copy/ an entry with its properties, duplicate IDs will
inevitably be produced. This is unavoidable in a plain text
system that allows you to edit the text in arbitrary ways, and a
portion of care on your side is needed to keep this system clean.
The hash is stored in the file =~/.emacs.d/.org-id-locations=.
This is also a change from previous versions where the file was
=~/.org=id-locations=. Therefore, you can remove this old file
if you have it. I am not sure what will happen if the =.emacs.d=
directory does not exists in your setup, but in modern Emacsen, I
believe it should exist. If you do not want to use IDs across
files, you can avoid the overhead with tracking IDs by
customizing the variable =org-id-track-globally=. IDs can then
still be used for links inside a single file.
IDs will also be used when you create a new link to an Org-mode
buffer. If you use =org-store-link= (normally at =C-c l=) inside
en entry in an Org-mode buffer, and ID property will be created
if it does not exist, and the stored link will be an =id:= link.
If you prefer the much less secure linking to headline text, you
can configure the variable =org-link-to-org-use-id=. The default
setting for this variable is =create-if-interactive=, meaning
that an ID will be created when you store a link interactively,
but not if you happen to be in an Org-mode file while you create
a remember note (which usually has a link to the place where you
were when starting remember).
The old syntax for setting HTML link attributes is no longer
supported. Existing links will not fail, but the attributes specified
in the old way will be ignored.
Tables, and Hyperlinks that represent inlined images, can now be
equipped with additional information that will be used during
export. The information will be taken from the following special
lines in the buffer and apply to the first following table or
link.
- #+CAPTION: :: The caption of the image or table. This string
should be processed according to the export backend, but
this is not yet done.
- #+LABEL: :: A label to identify the figure/table for cross
references. For HTML export, this string will become the
ID for the `<div class="figure">' element that encapsulates
the image tag and the caption. For LaTeX export, this
string will be used as the argument of a `\label{...}'
macro. These lables will be available for internal links
like `[[label][Table] ]'.
- #+ATTR_HTML: :: Attributes for HTML export of image, to be
added as attributes into the `<img...>' tag. This string
will not be processed, so it should have immediately the
right format.
- #+ATTR_LaTeX: :: Attributes for LaTeX export of images, to
be inserted into the optional argument of the
`\includegraphics[...]{file}' command, to specify scaling,
clipping and other options. This string will not be
processed, so it should have immediately the right
format, like `width=5cm,angle=90'
For LaTeX export, if either a caption or a label is given, the
element will be exported as a float, i.e. wrapped into a figure
or table environment.

This patch fixes these issues.
Tassilo Horn asked for this, because he finds the default behavior of
silently choosing a different row too confusing. I actually do agree.
The main use of this feature was running averages, if you need this
feature, you can customize the variable
`org-table-error-on-row-ref-crossing-hline'.
Moving trees up or down with XEmacs caused a problem when the tree is
at the beginning if the buffer or narrowed region. This patch
protects the relevant calls to outline-flag-region so that they are
only executed if the range is valid.

This patch add a new customization variable `org-tag-faces' that can
be used to specify such faces. The rest of the patch implements these
new faces in Org-mode buffers as well as in the agenda.
It seems that CSS and Java-script stuff should be quoted in a very
strange way in order to make sure that the resulting file functions
correct in current browsers *and* validates against various XHTML and
XML standards. To be honest, the quoting technique seem really
strange, but Sebastian Rose argues, that this is the way to handle
this issue.
Gnus uses w3m to wash HTML messages and installs w3m-minor-mode-map in
these buffers. Therefore, this patch makes sure that the special copy
command that converts HTML links to Org-mode links also gets installed
into the minor mode map.
This is as yet untested.
Calling `org-archive-to-archive-sibling' caused problems when used
several times in a row. The new killed subtree would be appended to
the current head of the kill-ring, instead of being pushed there. The
reason for this is that the command `kill-region', which is called by
`org-cut-subtree' changes the variable `this-command', so that during
the next archive command, `kill-region' will think that the previous
command was also a kill and do the append.
Normally this is wanted, to make sure that several kill commands
create one big yank string. But in this case it has to be avoided.
The patch fixes the problem by let-binding (and therefore protecting)
the value of `this-command' around the call to `org-cut-subtree'.

Harri Kiiskinen suggested that it might be useful to make the LOCATION
property an inherited property during iCalendar export. In this way
you can have set the LOCATION for a whole set of items by setting it
only in the parent.
While this will slow down iCalendar export for large files, I think it
can be quite useful. This patch does implement the basic code needed
for this functionality. However, you still need to tell Org that
LOCATION should be inherited, by setting org-use-property-inheritance.
If you set it to t, beware that this may trigger a significant
slowdown when creating the match view in the agenda. So it may be
better to set this variable to
(setq org-use-property-inheritance '("LOCATION"))
instead.
This patch improves the internal handling of the large number of
export options that Org-mode has. In particular, it now defines a
single constant, `org-export-plist-vars' that contains the full list
of options, and how these can be accessed through variables, and
through the #+OPTIONS line. Before the patch, there used to be a
separate list or the OPTIONS handling, which has gotten out of sync.
This now no longer can happen.
Also, this patch adds two new variables, `org-export-with-priority',
and `org-export-with-todo-keywords', which can be used to turn the
export of TODO keywords and priority cookies on and off, so that these
can simply disappear and not be shown in the exported file. In fact,
the default for the priority cookie is to remove it.
There were bugs in the mapping API, pointed to by Samuel Wales:
Manual says:
The following example counts the number of entries with TODO keyword
WAITING, in all agenda files.
(length (org-map-entries t "/+WAITING" nil 'agenda))
Org says invalid function for the string.
First of all, the example in the manual was wrong, the "nil" should be
gone. Second, the mapping function did not return all results in a
list, so that `length' could not count them.
This patch fixes these issues.
In addition to "<now>", "<today>", "<yesterday>", and
"<tomorrow>", there are more special values accepted now in
time comparisons in property searches: You may use strings
like =<+3d>= or =<-2w>=, with units d, w, m, and y for day,
week, month, and year, respectively
Thanks to Linday Todd for this proposal.
So far, the only way to select tags for inheritance was to
allow it for all tags, or to do a positive selection using
one of the more complex settings for
`org-use-tag-inheritance'. It may actually be better to
allow inheritance for all but a few tags, which was difficult
to achieve with this methodology.
This patch introduces a new option,
`org-tags-exclude-from-inheritance' which allows to specify an
exclusion list for inherited tags.
This patch does a lot of things. First, it makes sure that the tags
transferred to the agenda as text properties on each line are do carry
information about there origin (in the form of an `inherited' text
property). Then it modifies the function creating agenda lines so
that inherited tags will be listed and identified as such in the
agenda.
This new feature can be turned off with a new variable,
`org-agenda-show-inherited-tags'.
This file implements a special function to copy text from a w3m buffer
in a way that when the text is yanked back into an Org-mode buffer,
the links will be translated to Org syntax.
This key needs special treatment, because it needs to work *outside*
tables. The patch introduces a special command to call the
creation/conversion function if there is no conflicting binding to
`C-c |' outside of orgtbl-mode.
S-SPC did lead to an error in orgtbl-mode, because there is no binding
to this key. Now orgtbl-self-insert-command falls back on calling
self-insert-command for such cases.
