The API in the C runtime as well as in the Haskell, Python and Java binding is changed. Now instead of adding the literal callbacks to the concrete syntax you need to supply them every time when you need to parse. The main reason is: - referentially transparent API for Haskell - when we start using memory mapped files we will not be allowed to change anything in the grammar data structures. At that point the old API would be impossible to use.
This is a binding to the new GF runtime in C.
The files are:
PGF2.hsc -- a user API similar to Python and Java APIs
PGF2/FFI.hs -- an internal module with FFI definitions for
-- the relevant C functions
HOW TO COMPILE:
cabal install
HOW TO USE:
- Import PGF to the Haskell program that you're writing.
The Cabal infrastructure will make sure to tell the compiler
where to find the relevant modules. Example:
module Main where
import PGF2
import qualified Data.Map as Map
main = do
pgf <- readPGF "Foo.pgf"
let Just english = Map.lookup "FooEng" (languages pgf)
