A Python interpreter written in Rust

Installation

bash init_env.sh

Run

./test.sh <path/to/file.py> # compile and run
./test.sh <path/to/file.py> --bytecode # print the bytecode in JSON
./test.sh <path/to/file.py> --dis # Run python -m dis

Manual

Given a python file test.py

python compile_code.py test.py > test.bytecode

cd RustPython
cargo run ../test.bytecode 

Testing & debugging

./test_all.sh # Run all tests under tests/
  • If a test is expected to fail or raise exception, add xfail_* prefix to the filename.

Logging

RUST_LOG=debug ./tests_all.sh

TODOs

  • Native types => Partial
  • Control flow => if(v)
  • assert => OK
  • Structural types (list, tuple, object)
  • Strings
  • Function calls => Blocked by bytecode serializer
  • Modules import
  • Generators

Goals

  • Support all builtin functions

  • Runs the pybenchmark benchmark test

  • Run famous/popular python modules (which?)

  • Compatible with CPython 3.6

Rust version

rustc 1.20.0-nightly
