The Pytch compiler is currently written in Python 3.7.
To install the development environment, run
$ poetry install
Running
To launch the REPL:
$ poetry run pytch repl
To execute a file as a Pytch script:

Updating the syntax trees
To modify the syntax tree node types, update pytch/syntax_tree.txt
, then run:
$ ./bin/generate_syntax_trees.sh
Fuzzing the parser
To run the fuzzer on the Pytch parser, first be sure that the AFL
fuzzer is installed (e.g. with brew install afl-fuzz
). Next,
install the fuzzing dependencies:
$ poetry install --extras fuzz
Then you can run:
$ ./bin/fuzz.sh
