XML identifiers must start with an underscore or letter, and can contain
only a limited set of punctuation characters. Any IDs not adhering to
these rules are rewritten by writing the offending characters as Uxxxx,
where `xxxx` is the character's hex code.
Instead of encoding a giant (and incomplete) map, we now
just use unicode-transforms to normalize the text to
a canonical decomposition, and manipulate the result.
The new `toAsciiText` is equivalent to the old
`T.pack . mapMaybe toAsciiChar . T.unpack` but should be faster.
This is a bit more limited than with markdown, as documented
in the manual:
- The YAML block must be the first thing in the input.
- The leaf notes are parsed in isolation from the rest of
the document. So, for example, you can't use reference
links if the references are defined later in the document.
Closes#6537.
Add key-value pairs found in the attributes list of Header.Attr as
XML attributes on the corresponding section element.
Any key name not allowed as an XML attribute name is dropped, as
are keys with invalid values where they are defined as enums in
DocBook, and xml:id (for DocBook 5)/id (for DocBook 4) to not
intervene with computed identifiers.
[API change]
These are inefficient association list lookups.
Replace with more efficient functions in the writers that
used them (with 10-25% performance improvements in
haddock, org, rtf, texinfo writers).
Apparently Cabal sets a `pandoc_datadir` environment variable
so that the data files will be sought in the source directory
rather than in the final destination (where they aren't yet
installed).
So we no longer need to set `--data-dir` in the tests. We just
need to make sure `pandoc_datadir` is set in the environment
when we call the program in the test suite.
This will fix the issue with loading of pandoc.lua when
pandoc is built with `-embed_data_files`, reported in #7163.
Closes#7163.
T.P.Parsing: revise type of readWithM so that it takes a Text
rather than a polymorphic ToText value.
These typeclasses were there to ease the transition from String
to Text. They are no longer needed, and they may clash with
more useful versions under the same name.
This will require a bump to 2.13.
