GF.Text.Pretty provides the class Pretty and overloaded versions of the pretty printing combinators in Text.PrettyPrint, allowing pretty printable values to be used directly instead of first having to convert them to Doc with functions like text, int, char and ppIdent. Some modules have been converted to use GF.Text.Pretty, but not all. Precedences could be added to simplify the pretty printers for terms and patterns. GF.Infra.Location contains the types Location and L, factored out from GF.Grammar.Grammar, and the class HasSourcePath. This allowed the import of GF.Grammar.Grammar to be removed from GF.Infra.CheckM, making it more like a pure library module.
DESCRIPTION
The Grammatical Framework (=GF) 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)
