* XML.toEntities: changed type to Text -> Text.
* Shared.tabFilter -- fixed so it strips out CRs as before.
* Modified writers to take Text.
* Updated tests, benchmarks, trypandoc.
[API change]
Closes#3731.
We already lower-bound tagsoup at 0.13.7, which means we were always
running the compatibility layer (it was conditional on min value
0.13). Better to just use `lookupEntity` from the library directly, and
convert a string to a char if need be.
- Text.Pandoc.XML.fromEntities: handle entities without a
semicolon. Always lookup character references with the
trailing ';', even if it wasn't present. And never add
it when looking up numerical entities. (This is what
tagsoup seems to require.)
- Text.Pandoc.Parsing.characterReference: Always lookup
character references with the trailing ';', and leave off
the ';' when looking up numerical entities.
This fixes a regression for e.g. `⟨`.
* 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.
