A Python-3 (CPython >= 3.5.0) Interpreter written in Rust 🐍 😱 🤘.
RustPython requires Rust latest stable version (e.g 1.38.0 at Oct 1st 2019).
To check Rust version:
rustc --version If you wish to update,
rustup update stable.
To test RustPython, do the following:
$ git clone https://github.com/RustPython/RustPython cd RustPython $ cargo run demo.py Hello, RustPython!
Or use the interactive shell:
$ cargo run Welcome to rustpython >>>>> 2+2 4
You can also install and run RustPython with the following:
$ cargo install rustpython rustpython Welcome to the magnificent Rust Python interpreter >>>>>
Or through the
conda package manager:
$ conda install rustpython -c conda-forge rustpython
You can compile RustPython to a standalone WebAssembly WASI module so it can run anywhere.
wapm install rustpython wapm run rustpython >>>>> 2+2 4
You can build the WebAssembly WASI file with:
cargo build --release --target wasm32-wasi --features="freeze-stdlib"
Note: we use the
freeze-stdlibto include the standard library inside the binary.
Interested in exposing Python scripting in an application written in Rust,
perhaps to allow quickly tweaking logic where Rust's compile times would be inhibitive?
examples/mini_repl.rs may be of some assistance.
RustPython is in a development phase and should not be used in production or a fault intolerant setting.
Our current build supports only a subset of Python syntax.
Contribution is also more than welcome! See our contribution section for more information on this.
Checkout those talks on conferences:
Allthough rustpython is a very young project, it is already used in the wild:
Currently along with other areas of the project, documentation is still in an early phase.
You can read the online documentation for the latest release.
You can also generate documentation locally by running:
$ cargo doc # Including documentation for all dependencies $ cargo doc --no-deps --all # Excluding all dependencies
Documentation HTML files can then be found in the
Contributions are more than welcome, and in many cases we are happy to guide contributors through PRs or on gitter. Please refer to the development guide as well for tips on developments.
With that in mind, please note this project is maintained by volunteers, some of the best ways to get started are below:
Most tasks are listed in the
issue tracker. Check issues
good first issue if you wish to start coding.
Another approach is to checkout the source code: builtin functions and object methods are often the simplest and easiest way to contribute.
You can also simply run
./whats_left.sh to assist in finding any unimplemented
As of now the standard library is under construction. You can use a standard library by setting the RUSTPYTHONPATH environment variable.
To do this, follow this method:
$ export RUSTPYTHONPATH=~/GIT/RustPython/Lib $ cargo run -- -c 'import xdrlib'
You can play around with other standard libraries for python. For example, the ouroboros library.
Chat with us on gitter.
