The marshaling functions for pandoc's AST are extracted into a separate
package. The package comes with a number of changes:
- Pandoc's List module was rewritten in C, thereby improving error
messages.
- Lists of `Block` and `Inline` elements are marshaled using the new
list types `Blocks` and `Inlines`, respectively. These types
currently behave identical to the generic List type, but give better
error messages. This also opens up the possibility of adding
element-specific methods to these lists in the future.
- Elements of type `MetaValue` are no longer pushed as values which
have `.t` and `.tag` properties. This was already true for
`MetaString` and `MetaBool` values, which are still marshaled as Lua
strings and booleans, respectively. Affected values:
+ `MetaBlocks` values are marshaled as a `Blocks` list;
+ `MetaInlines` values are marshaled as a `Inlines` list;
+ `MetaList` values are marshaled as a generic pandoc `List`s.
+ `MetaMap` values are marshaled as plain tables and no longer
given any metatable.
- The test suite for marshaled objects and their constructors has
been extended and improved.
- A bug in Citation objects, where setting a citation's suffix
modified it's prefix, has been fixed.

Pandoc
The universal markup converter
Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can convert from

Pandoc can also produce PDF output via LaTeX, Groff ms, or HTML.
Pandoc’s enhanced version of Markdown includes syntax for tables, definition lists, metadata blocks, footnotes, citations, math, and much more. See the User’s Manual below under Pandoc’s Markdown.
Pandoc has a modular design: it consists of a set of readers, which parse text in a given format and produce a native representation of the document (an abstract syntax tree or AST), and a set of writers, which convert this native representation into a target format. Thus, adding an input or output format requires only adding a reader or writer. Users can also run custom pandoc filters to modify the intermediate AST (see the documentation for filters and Lua filters).
Because pandoc’s intermediate representation of a document is less expressive than many of the formats it converts between, one should not expect perfect conversions between every format and every other. Pandoc attempts to preserve the structural elements of a document, but not formatting details such as margin size. And some document elements, such as complex tables, may not fit into pandoc’s simple document model. While conversions from pandoc’s Markdown to all formats aspire to be perfect, conversions from formats more expressive than pandoc’s Markdown can be expected to be lossy.
