We can't always tell if it's LaTeX, ConTeXt, or plain TeX.
Better just to use "tex" always.
Also changed:
ConTeXt writer: now outputs raw "tex" blocks as well as "context".
(Closes#969).
RST writer: uses ".. raw:: latex" for "tex" content.
(RST doesn't support raw context anyway.)
Note that if "context" or "latex" specifically is desired,
you can still force that in a markdown document by using
the raw attribute (see MANUAL.txt):
```{=latex}
\foo
```
Note that this change may affect some filters, if they assume that raw
tex parsed by the Markdown reader will be RawBlock (Format "latex").
In most cases it should be trivial to modify the filters to accept
"tex" as well.
This rewrite is primarily motivated by the need to
get macros working properly. A side benefit is that the
reader is significantly faster (27s -> 19s in one
benchmark, and there is a lot of room for further
optimization).
We now tokenize the input text, then parse the token stream.
Macros modify the token stream, so they should now be effective
in any context, including math. Thus, we no longer need the clunky
macro processing capacities of texmath.
A custom state LaTeXState is used instead of ParserState.
This, plus the tokenization, will require some rewriting
of the exported functions rawLaTeXInline, inlineCommand,
rawLaTeXBlock.
* Added Text.Pandoc.Readers.LaTeX.Types (new exported module).
Exports Macro, Tok, TokType, Line, Column. [API change]
* Text.Pandoc.Parsing: adjusted type of `insertIncludedFile`
so it can be used with token parser.
* Removed old texmath macro stuff from Parsing.
Use Macro from Text.Pandoc.Readers.LaTeX.Types instead.
* Removed texmath macro material from Markdown reader.
* Changed types for Text.Pandoc.Readers.LaTeX's
rawLaTeXInline and rawLaTeXBlock. (Both now return a String,
and they are polymorphic in state.)
* Added orgMacros field to OrgState. [API change]
* Removed readerApplyMacros from ReaderOptions.
Now we just check the `latex_macros` reader extension.
* Allow `\newcommand\foo{blah}` without braces.
