Plugin for Ape Ethereum Framework for compiling Vyper contracts

Project description

Quick Start

Ape compiler plugin around VVM

Dependencies

  • python3 version 3.8 or greater, python3-dev

Installation

via pip

You can install the latest release via pip:

pip install ape-vyper

via setuptools

You can clone the repository and use setuptools for the most up-to-date version:

git clone https://github.com/ApeWorX/ape-vyper.git
cd ape-vyper
python3 setup.py install

Quick Usage

First, place Vyper contract source files (files with extension .vy) in your Ape project's contracts folder. An example Vyper contract can be found here. Then, from your root Ape project folder, run the command:

ape compile

The .vy files in your project will compile into ContractTypes that you can deploy and interact with in Ape.

Interfaces

You can not compile interface source files directly. Thus, you must place interface files in a directory named interfaces in your contracts_folder e.g. contracts/interfaces/IFace.vy. Then, these files can be imported in other .vy sources files via:

import interfaces.IFace as IFace

Alternatively, use JSON interfaces from dependency contract types by listing them under the import_remapping key:

# Use `voting` example contracts from Vyperlang repo.
dependencies:
  - name: VyperVoting
    github: vyperlang/vyper
    contracts_folder: examples/voting/
    version: v0.3.7

# Automatically allow importing voting contracts in your project.
vyper:
  import_remapping:
    - "voting=VyperVoting@v0.3.7"

Import the voting contract types like this:

# @version 0.3.7

import voting.ballot as ballot
