Linear time composable parser for PEG grammars frisby is a parser library that can parse arbitrary PEG grammars in linear time. Unlike other parsers of PEG grammars, frisby need not be supplied with all possible rules up front, allowing composition of smaller parsers. . PEG parsers are never ambiguous and allow infinite lookahead with no backtracking penalty. Since PEG parsers can look ahead arbitrarily, they can easily express rules such as the maximal munch rule used in lexers, meaning no separate lexer is needed. . In addition to many standard combinators, frisby provides routines to translate standard regex syntax into frisby parsers.

Functional MetaPost is a Haskell frontend to the MetaPost language Functional MetaPost is a Haskell frontend to the MetaPost language by John Hobby. Users write their graphics as Haskell programs, which then emit MetaPost code that can be compiled into encapsulated PostScript files and smoothly included into e.g. LaTeX. A collection of useful examples how to use Functional MetaPost can be found in the user's manual. The document doesn't offer very much detail in terms of explanations, but the code samples are quite helpful. Further documentation can be found in the original thesis that describes the implementation. The text is also available in German. Last but not least, there is a tutorial that offers many helpful examples (which is also available in German).

Generically derived enumerations. This package provides a way to generically obtain every possible value of a type, provided that the generic representation of the type is compatible.
package
generic-lexicographic-order Derive Bounded and Enum for sum types and Enum for product types Derive generic instances of Bounded and/or Enum for sums, and Enum instances for products, based on the instances of their components. These instances are designed to cohere with the stock-derived Ord instance.

Backwards-compatible orphan instances for ghc-bignum ghc-bignum-orphans defines orphan instances that mimic instances available in later versions of ghc-bignum to a wider (older) range of compilers. ghc-bignum-orphans does not export anything except the orphan instances themselves.
