This is unsupported legacy code
This project has a cabal and stack file. The easiest probably is to use stack.
Run stack ghci to load all necessary files into a GHCi session.
There currently are two test functions Subgrammar.GFRule.test and Subgrammar.GFSubtree.
The test functions require the Exemplum grammar (both the PGF and the ExemplumEng.gf file) and the GF RGL
The relevant pathes can be adjusted in the Subgrammar/Common.hs file.
The tests load a grammar and use a set of example sentences to generate a new grammar. Afterwards it is tested that the examples are really covered.
To profile the code you can build the code with profiling:
stack build --executable-profiling --ghc-options "-threaded"
or
stack install --executable-profiling --ghc-options "-threaded -rtsopts" --pedantic
Afterwards you can run it with profiling enabled:
stack exec --rts-options -p subgrammar-extraction
This results in a file called subgrammar-extraction.prof that can be
analysed further.
By also adding -h you can also get the heap analysis as a .hp file that
can be converted by using hp2ps.
