It was only needed for compatibility with directory<1.2, but directory>=1.2 has been shipped with ghc since ghc-7.6. Note: time-compat-1.9.* (the current version) is a completely different package, that does not provide the needed function toUTCTime, which was provided in time-compat-0.1.*.
Grammatical Framework (GF)
The Grammatical Framework is a grammar formalism based on type theory. It consists of:
- a special-purpose programming language
- a compiler of the language
- a generic grammar processor
The compiler reads GF grammars from user-provided files, and the generic grammar processor performs various tasks with the grammars:
- generation
- parsing
- translation
- type checking
- computation
- paraphrasing
- random generation
- syntax editing
GF particularly addresses four aspects of grammars:
- multilinguality (parallel grammars for different languages)
- semantics (semantic conditions of well-formedness, semantic properties of expressions)
- grammar engineering (modularity, abstractions, libraries)
- embeddability in programs written in other languages (C, C++, Haskell, Java, JavaScript)
Compilation and installation
The simplest way of installing GF is with the command:
cabal install
