via setuptools

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

Quick Usage

Ape is primarily meant to be used as a command line tool. Here are some things you can use ape to do:

# Work with your accounts
$ ape accounts list

# Compile your project's smart contracts
$ ape compile --size

# Run your tests with pytest
$ ape test -k test_only_one_thing --coverage --gas

# Connect an IPython session through your favorite provider
$ ape console --network ethereum:mainnet:infura

# Add new plugins to ape
$ ape plugins add plugin-name

Ape also works as a package. You can use the same networks, accounts, and projects from the ape package as you can in the cli:

# Work with registered networks, providers, and blockchain ecosystems (like Ethereum)
from ape import networks
with networks.ethereum.mainnet.use_provider("infura"):
    ...  # Work with the infura provider here

# Work with test accounts, local accounts, and (WIP) popular hardware wallets
from ape import accounts
a = accounts[0]  # Load by index
a = accounts["example.eth"]  # or load by ENS/address
a = accounts.load("alias") # or load by alias

# Work with contract types
from ape import project
c = a.deploy(project.MyContract, ...)
c.viewThis()  # Make Web3 calls
c.doThat({"from": a})  # Make Web3 transactions
assert c.MyEvent[-1].caller == a  # Search through Web3 events
