Alternatives to RustPython?

[michaelwooley]

Do we really need to have python reimplemented in rust?

What about:

• cpython itself?
• Python bindings in rust?

python 3.11 wasm support

Experiment branch | python/cpython wasm | OG tutorial @ ethanhs/python-wasm | demo

• 🟢 Pretty incredible. Basically works out of the box.
• 🟢 os, sqlite3, and most of rest of stdlib just works out of box.
• 🟢 Has a builtin FS! Amazing but WTF? HOW?!
• 🟡 JS glue generated by emscripten a mess:
  • No module boundaries/not importable (as written)
  • Lots of dead code? (Or just code that we throw into the global scope that may be used by some sneakily imported code?)
• 🟡 Works on a pipes basis (stdin/stdout/stderr). Interaction with stdin still needs to be figured out.
• 🟡 🧪 Experimental

PyO3

python bindings for rust

GitHub | docs

• 🔴 Static linking of python is still experimental:
  • WASM and Python PyO3/pyo3#1935
  • Static Build of pyo3 (embedding python interpreter) PyO3/pyo3#416
  • Docs: "Statically embedding the Python interpreter"

(More looks) Emscripten investigate

• emcc's settings.js. All settings with descriptions.
• emcc -s flags/environment
