Most PGF web API commands that produce linearizations now accept an unlexer parameter. Possible values are "text", "code" and "mixed". The web service now include Date and Last-Modified headers in the HTTP, responses. This means that browsers can treat responses as static content and cache them, so it becomes less critical to cache parse results in the server. Also did some cleanup in PGFService.hs, e.g. removed a couple of functions that can now be imported from PGF.Lexing instead.
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)
