Support for standard org-blocks is improved. The parser now handles
"HTML", "LATEX", "ASCII", "EXAMPLE", "QUOTE" and "VERSE" blocks in a
sensible fashion.
This fixes the org-reader's handling of sub- and superscript
expressions. Simple expressions (like `2^+10`), expressions in
parentheses (`a_(n+1)`) and nested sexp (like `a_(nested()parens)`) are
now read correctly.
Support all of the following variants as valid ways to define inline or
display math inlines:
- `\[..\]` (display)
- `$$..$$` (display)
- `\(..\)` (inline)
- `$..$` (inline)
This closes#1223. Again.
In particular we now pick up on attributes. Since pandoc links
can't have attributes, we enclose the whole link in a span
if there are attributes.
Closes#1008.
Instead of being ignored, attributes are now parsed and
included in Span inlines.
The output will be a bit different from stock textile:
e.g. for `*(foo)hi*`, we'll get `<em><span class="foo">hi</span></em>`
instead of `<em class="foo">hi</em>`. But at least the data is
not lost.
Org-mode and Pandoc use different language identifiers, marking source
code as being written in a certain programming language. This adds more
translations from identifiers as used in Org to identifiers used in
Pandoc.
The full list of identifiers used in Org and Pandoc is available through
http://orgmode.org/manual/Languages.html and `pandoc -v`, respectively.
Text such as /*this*/ was not correctly parsed as a strong, emphasised
word. This was due to the end-of-word recognition being to strict as it
did not accept markup chars as part of a word. The fix involves an
additional parser state field, listing the markup chars which might be
parsed as part of a word.
The default pandoc ParserState is replaced with `OrgParserState`. This
is done to simplify the introduction of new state fields required for
efficient Org parsing.
The reader did not correctly parse inline markup. The behavoir is now as follows.
(a) The markup must start at the start of a line, be inside previous
inline markup or be preceeded by whitespace.
(b) The markup can not span across paragraphs (delimited by \n\n)
(c) The markup can not be followed by a alphanumeric character.
(d) Square brackets can be placed around the markup to avoid having
to have white space before it.
In order to make these changes it was either necessary to convert the parser to return a list of inlines or to convert the whole reader to use the builder. The latter approach whilst more work makes a bit more sense as it becomes easy to arbitarily append and prepend elements without changing the type.
Tests are accordingly updated in a later commit to reflect the different normalisation behavoir specified by the builder monoid.
