Module documentation for 0.9.1

Text
- Text.JSON

JSON (JavaScript Object Notation) is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. It is based on a subset of the JavaScript Programming Language, Standard ECMA-262 3rd Edition - December 1999.

This library provides a parser and pretty printer for converting between Haskell values and JSON.

Version 0.4.1: released 2009-01-12; changes from 0.3.6

* Addition of extra JSON instances:
- IntMap, Set, Array, IntSet

* Dropped initial letter case-lowering for constructors:
- Maybe's constructors are mapped to "Nothing","Just".
- Either's constructors are mapped to "Left", "Right".

* Ordering's are represented by their constructor names (was
funky int-mapping.)

* JSON.Text.Result is now an instance of MonadError; contributed
by Andy Gimblett.

* Included Lennart Augustsson's contributed generic JSON encoder,
in Text.JSON.Generic

* Optional JSON dict-mapping for Data.Map and Data.IntMap
