* Depend on pandoc 1.12.
* Added yaml dependency.
* `Text.Pandoc.XML`: Removed `stripTags`. (API change.)
* `Text.Pandoc.Shared`: Added `metaToJSON`.
This will be used in writers to create a JSON object for use
in the templates from the pandoc metadata.
* Revised readers and writers to use the new Meta type.
* `Text.Pandoc.Options`: Added `Ext_yaml_title_block`.
* Markdown reader: Added support for YAML metadata block.
Note that it must come at the beginning of the document.
* `Text.Pandoc.Parsing.ParserState`: Replace `stateTitle`,
`stateAuthors`, `stateDate` with `stateMeta`.
* RST reader: Improved metadata.
Treat initial field list as metadata when standalone specified.
Previously ALL fields "title", "author", "date" in field lists
were treated as metadata, even if not at the beginning.
Use `subtitle` metadata field for subtitle.
* `Text.Pandoc.Templates`: Export `renderTemplate'` that takes a string
instead of a compiled template..
* OPML template: Use 'for' loop for authors.
* Org template: '#+TITLE:' is inserted before the title.
Previously the writer did this.
Previously, a LaTeX citation would always be parsed as a Citation
element, with the raw LaTeX in the [Inline] part.
Now, the LaTeX citation is parsed as a Citation element only if
`--biblio` was specified (i.e. only if there is a nonempty set
of references in readerReferences). Otherwise it is parsed as
raw LaTeX.
This will make it possible to simplify some things in the markdown
writer. It also makes the LaTeX reader behave more like the Markdown
reader.
We convert these to pandoc standard names, e.g. "numberLines"
for "numbers=left", "startFrom=100" from "firstnumber=100".
Still need to add code to convert the language names.
Now latex macro definitions are preserved when output is latex,
and applied when it is another format, as originally intended.
Partially addresses #730.
\providecommand is still not supported. For this we need changes
to texmath.
This reverts commit da87837318.
Reason: The code was overzealous and would rule out some things
we want to be able to do, like include the same file multiple
times.
Previously this was done in src/pandoc.hs, which made it difficult
for library users.
* Removed readerCitations in ReaderOptions.
* Added readerReferences and readerCitationStyle to ReaderOptions.
* Moved use of processBiblio from main program to the
markdown and LaTeX readers.
Now it will also try to parse block commands. This is usually
what we want, given how rawLaTeXInline is used in the markdown
and textile readers. If a block-level LaTeX command is used
in the middle of a paragraph (e.g. `\subtitle` inside a title),
we can treat it as raw inline LaTeX.
This allows the markdown reader to treat '\begin' (not followed
by an argument) as a raw string rather than erroring out when
it doesn't find a '{'.
Closes#622.
