Org rules for allowed characters before or after markup chars were not
checked for verbatim text. This resultet in wrong parsing outcomes of
if the verbatim text contained e.g. space enclosed markup characters as
part of the text (`=is_substr = True=`). Forcing the parser to update
the positions of allowed/forbidden markup border characters fixes this.
This fixes#3016.
Div blocks handling is changed to make the output look more like
idiomatic org mode:
- Div-wrapped content is output as-is if the div's attribute is the
null attribute.
- Div containers with an id but neither classes nor key-value pairs
are unwrapped and the id is added as an anchor.
- Divs with classes associated with greater block elements are
wrapped in a `#+BEGIN`...`#+END` block.
- The old behavior for Divs with more complex attributes is kept.
Some less-than-smart code required a pragma switching of overlapping
pattern warnings in order to compile seamlessly. Using view patterns
makes the code easier to read and also doesn't require overlapping
pattern checks to be disabled.
Handling of archived trees can be modified using the `arch` option.
Archived trees are either dropped, exported completely, or collapsed to
include just the header when the `arch` option is nil, non-nil, or
`headline`, respectively.
Comment trees were handled after parsing, as pattern matching on lists
is easier than matching on sequences. The new method of reading
documents as trees allows for more elegant subtree removal.
Emacs org-mode is based on outline-mode, which treats documents as trees
with headlines are nodes. The reader is refactored to parse into a
similar tree structure. This simplifies transformations acting on
document (sub-)trees.
We treat display math like block quotes, and apply FirstParagraph style
to paragraphs that follow them. These can be styled as the user
wishes. (But, when the user is using indentation, this allows for
paragraphs to continue after display math without indentation.)
Figure labels given as `#+LABEL: thelabel` are used as the ID of the
respective image. This allows e.g. the LaTeX to add proper `\label`
markup.
This fixes half of #2496 and #2999.
The link
`<foo>`_
should have `foo` as both its link text and its URL.
See RST spec at
<http://docutils.sourceforge.net/docs/ref/rst/restructuredtext.html#embedded-uris-and-aliases>
"The reference text may also be omitted, in which case the URI will be
duplicated for use as the reference text. This is useful for relative
URIs where the address or file name is also the desired reference text:
See `<a_named_relative_link>`_ or `<an_anonymous_relative_link>`__
for details."
Closes Debian #828167 -- reported by Christian Heller.
Previously they were processed, very unintuitively, in R->L
order, so that `markdown-tex_math_dollars+tex_math_dollars`
had `tex_math_dollars` disabled.
Closes#2995.
