On my laptop these changes speed up the full build of the RGL and example grammars with 'cabal build' from ~95s to ~43s and the zero build from ~18s to ~5s. The main change is the introduction of the module GF.CompileInParallel that replaces GF.Compile and the function GF.Compile.ReadFiles.getAllFiles. At present, it is activated with the new -j flag, and it is only used when combined with --make or --batch. In addition, to get parallel computations, you need to add GHC run-time flags, e.g., +RTS -N -A20M -RTS, to the command line. The Setup.hs script has been modified to pass the appropriate flags to GF for parallel compilation when compiling the RGL and example grammars, but you need a recent version of Cabal for this to work (probably >=1.20). Some additonal refactoring were made during this work. A new monad is used to avoid warnings/error messages from different modules to be intertwined when compiling in parallel, so some functios that were hardiwred to the IO or IOE monads have been lifted to work in arbitrary monads that are instances in the appropriate classes.
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)
