In addition to warnings, the Check monad in GF.Infra.CheckM can now accumulate errors. There are two new functions checkAccumError: Message -> Check () accumulateError :: (a -> Check a) -> a -> Check a The former (with the same type as checkWarn) is used to report an accumulated (nonfatal) error. The latter converts fatal errors into accumulated errors. Accumulated errors are reported as regular errors by runCheck. Also, the Check monad type has been made abstract.
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)
