This patch adds support functionality for the new code references. It
makes sure that `C-c C-o' will follow a code reference correctly. It
also extends the command org-store-link to actually create a new code
reference cookie when used in a source code temporary buffer created
with "C-c '". The new link will be stored, so that it can be inserted
with `C-c C-l'. When inserting such a link, no description will be
prompted for, because these coderef links should best not have a
description part.
This patch covers the three main backends, html, latex, and ascii. It
adds the code to make sure the coderef links identified by the
preprocessing will be implemented correctly when a backend does its work.
When refiling to the current file, the completion commands do not show
the file name. This was broken because I had switched from comparing
truenames to normal names. Now I am using expanded names, this is fast
and works well.
This patch introduces three improvements to refile target construction,
which should speed these functions up significantly.
1. A faster way to move up a level in the outline hierarchy
2. A better way to construct the outline path, in the case
that the command is scanning the entire hierarchy anyway
3. Avoid comparing the true-names of files.
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).
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.
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.
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'.
