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
