Lines preceded by a colon are treated as fixed-width examples.
This commit improves the moment when the protection of these lines
happens during preprocessing. And it enforces that a space must
follow the colon for the line to be treated in this way.
1. Export hangs during LaTeX export. That was a bug using an empty
regular expression that was defined only locally in Org files, but
not in the buffer used by the LaTeX exporter.
2. Underscores in links can get special treatment by the LaTeX
exporter. Now the link is protected from this.
When including s file in example or src markup, you can now also
specify the switches for code references and line numbering that work
also when directly adding SRC or EXAMPLE blocks.

This commit removes some of the stuff that was specific for the LaTeX
exporter, and falls back to the default configuration that works for
all backends.
Here is what the commit does:
- The variable `org-export-latex-remove-from-headlines' is now
obsolete. Instead, also LaTeX export now responds to the settings
in the variables org-export-with-todo-keywords',
`org-export-with-priority', and `org-export-with-tags' and in the
corresponding OPTION settings.
- Removal of time stamps and related keywords now already happens in
the preprocessor, so that it will be perfectly the same for all
backends.
- The list functions have been extended to accept an additional
parameter list, to overrule the default setting for a particular
list function. This is used to make the checkbox appearance in
LaTeX configurable, through the new variable
`org-export-latex-list-parameters'.
This patch introduces more hooks for preprocessing the export buffer,
at various strategic moments. See the Changes.org file for a
description of the hooks.
Org-mode allows multiple references to the same footnote. However,
the HTML exporter cannot use the same name for all these references,
because names have to be unique. This patch appends numbers to
footnote reference names, to make sure they remain unique.
The dark side of this patch means that from the footnote definition,
there is only a single link, to the first reference of the note.
However, in a browser you can always press BACK to go back after
jumping to a footnote definition.
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.
This patch covers the much of the new line numbering and code line
referencing.
We introduce a new function with the longish name
`org-export-replace-src-segments-and-examples'. It is an extension of
the earlier `org-export-replace-src-segments'. It now also covers
EXAMPLE blocks, not only source code blocks. This was necessary to
allow line numbering also in EXAMPLE blocks.
Both clock types now accept a string with options which will be given
in the BEGIN line. Options currently recognized are -n, +n, and -r.
A bit unsatisfactory about this patch may be that LaTeX-specific code
is now defined in org-exp.el, maybe eventually we want to think of a
way to move this code back to org-export-latex.el. Really, all it
does is adding line numbers and wrapping them into a verbatim
environment.
Besides adding line numbers in a backend specific way, this patch also
adds code to search or special cookies in source code, like "((1))" or
"((name))". These are labels that can be addressed by links as
references to specific line in source code.
This patch adds a new constant with javascript functions. Each
exported HTML file will contain these definitions. Also, we add to
the default export CSS style a new class, code-highlighted, which will
be used to highlight lines in code whenever the mouse overs over a
link to this line.
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.
