Using AJAX instead of JSONP can give better caching in the browser, since the URL doesn't need to contain a (dynamically generated) callback function name. But because of the same origin policy in JavaScript, AJAX can only be used when the HTML file is served from the same server as the PGF. The new function http_get_json in support.js uses AJAX if this is the case, and falls back to JSONP otherwise.
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)
