In this repository we present a formal semantics of Vyper. For more details, refer to wiki.
WARNING: This repository has not been independently audited for security. Use with caution.
KVyper can be used to compile Vyper programs to EVM bytecode, being comparable to the production Vyper compiler.
First, build K after installing the prerequisites in k/README.md (after the first command):
$ git submodule update --init k
$ cd k
$ mvn package -DskipTests
Add the bin directory to your path:
$ export PATH="`pwd`/k-distribution/target/release/k/bin:$PATH"
Then, build KVyper:
$ kompile --syntax-module VYPER-ABSTRACT-SYNTAX vyper-lll/vyper-lll-post.k
$ kompile --syntax-module LLL-EVM-INTERFACE lll-evm/lll-evm.k
Now you can run KVyper (Python 3.6 required):
$ python3.6 kvyper.py <pgm>.v.py
For example,
$ python3.6 kvyper.py tests/examples/token/ERC20.v.py
To contribute to KVyper: file issues, submit pull requests, and join the community K Riot channel, which includes a number of K experts.
