Experimental. This builds against local checkouts, listed in
cabal.project, of pandoc-types and the dependencies that use it
(citeproc, texmath, commonmark-pandoc, pandoc-lua-marshal), in deps/.
In pandoc-types, Meta and MetaMap now hold an OMap instead of a Map.
Code that used Map functions on metadata now uses Data.Map.Ordered.
Metadata fields keep their order:
- YAML metadata (metadata blocks, --metadata-file, references) is
read into a type whose mappings keep the order of the input; scalars
are converted as before. Metadata in defaults files is still read
through aeson, so its keys come out sorted.
- The JSON reader and JSON filters use pandoc-types' new decodePandoc,
which preserves the order of metadata fields.
- Lua filters preserve the order (via pandoc-lua-marshal).
Expected test outputs are updated: metadata now appears in the order
in which readers add fields, rather than sorted by key.
