Getting Started

See Installing Vyper to install vyper. See Tools and Resources for an additional list of framework and tools with vyper support. See Documentation for the documentation and overall design goals of the Vyper language.

See learn.vyperlang.org for learning Vyper by building a Pokémon game. See try.vyperlang.org to use Vyper in a hosted jupyter environment!

Note: Vyper is beta software, use with care

Installation

See the Vyper documentation for build instructions.

Compiling a contract

To compile a contract, use:

vyper your_file_name.vy

generate bytecode

vyper -f bytecode file-name.vy > file-name.bin

generate abi

vyper -f abi file-name.vy > file-name.abi

There is also an online compiler available you can use to experiment with the language and compile to bytecode and/or IR.

Note: While the vyper version of the online compiler is updated on a regular basis it might be a bit behind the latest version found in the master branch of this repository.

Testing (using pytest)

(Complete installation steps first.)

make dev-init
python setup.py test

Developing (working on the compiler)

A useful script to have in your PATH is something like the following:

$ cat ~/.local/bin/vyc
#!/usr/bin/env bash
PYTHONPATH=. python vyper/cli/vyper_compile.py "$@"

To run a python performance profile (to find compiler perf hotspots):

PYTHONPATH=. python -m cProfile -s tottime vyper/cli/vyper_compile.py "$@"

To get a call graph from a python profile, https://stackoverflow.com/a/23164271/ is helpful.
