py-lll¶
An LLL compiler for Python.
LLL (Low-level Lisp-like Language) is a smart contract programming language for the Ethereum blockchain. It seeks to provide a thin, human-readable layer over the atomic operations that occur during execution of a smart contract on the EVM (Ethereum Virtual Machine).
LLL is available in various flavors as a stand-alone language and is also used as an IR (intermediate representation) during compilation of contracts written in the Vyper smart contract language. The py-lll project implements the variety of LLL used as an IR by Vyper.
This project is intended to provide the following:
- A compiler for contracts written in LLL
- Documentation of LLL and its features
- A maximally transparent and maintainable implementation of LLL
- A flavor of LLL useful as an IR for higher-level smart contract languages
To fulfill these goals, py-lll favors simplicity over expressiveness.
