The command "gf -server" now starts a simple HTTP server on port 41295, providing a simple web API to the GF compiler. It currently support the follwing operations: * creating new temporary directories for grammar uploads, * uploading grammars files for use in the GF shell, * executing GF shell commands, and * accessing static files. This means that GF now depends on some additional networking related packages, but they should be available and easy to install on all platforms. There is also a new configuration flag "server" in gf.cabal, so GF will be compiled without support for server mode if the extra packages are unavailable. Note that running gf -server while connected to the internet can be a security risk. To prevent unauthorized access to the rest of the system, it is advisable to run the server in GF_RESTRICTED mode and as a user with suitably restricted file permissions.
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)
