Gramatron preprocessing scripts

In this folder live the scripts to convert a grammar (some examples in the grammars/ subfolder) into a serialized Automaton.

You need as first to convert the grammar to the GNF form using the gnf_converter.py Python script.

Then use the output as input of the construct_automata crate.

Here an example using the Ruby grammar:

./gnf_converter.py --gf grammars/ruby_grammar.json --out ruby_gnf.json --start PROGRAM
cd construct_automata
RUSTFLAGS="-C target-cpu=native" cargo run --release -- --gf ../ruby_gnf.json --out ../ruby_automaton.postcard

You can add the --limit flag to limit the stack size, as described in the Gramatron paper.
