1. The default encoding is changed from Latin-1 to UTF-8. 2. Alternate encodings should be specified as "--# -coding=enc", the old "flags coding=enc" declarations have no effect but are still checked for consistency. 3. A transitional warning is generated for files that contain non-ASCII characters without specifying a character encoding: "Warning: default encoding has changed from Latin-1 to UTF-8" 4. Conversion to Unicode is now done *before* lexing. This makes it possible to allow arbitrary Unicode characters in identifiers. But identifiers are still stored as ByteStrings, so they are limited to Latin-1 characters for now. 5. Lexer.hs is no longer part of the repository. We now generate the lexer from Lexer.x with alex>=3. Some workarounds for bugs in alex-3.0 were needed. These bugs might already be fixed in newer versions of alex, but we should be compatible with what is shipped in the Haskell Platform.
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)
