Quick Usage

In a project directory where there are .cairo files in your contracts/ directory, run the compile command:

ape compile

Configure Dependencies

You can configure dependencies, such as from GitHub, using your ape-config.yaml file.

There are two things you need to add:

1. Add your dependency to Ape's root dependencies: key to trigger downloading and compiling it.
2. Configure the ape-cairo plugin to load that dependency in your project.

For more information on dependencies, see this guide.

Your resulting ape-config.yaml will look something like:

dependencies:
  - name: OpenZeppelinCairo
    github: OpenZeppelin/cairo-contracts
    version: 0.1.0
    contracts_folder: src

cairo:
  dependencies:
    - OpenZeppelinCairo@0.1.0

NOTE: We are changing the contracts/ folder to be src for this dependency.

Now, in my contracts/ folder, I can import from openzeppelin:

from openzeppelin.token.erc20.library import (
    ERC20_name,
    ERC20_symbol,
    ERC20_totalSupply,
    ERC20_decimals,
    ERC20_balanceOf,
    ERC20_allowance,
    ERC20_mint,
    ERC20_burn,
    ERC20_initializer,
    ERC20_approve,
    ERC20_increaseAllowance,
    ERC20_decreaseAllowance,
    ERC20_transfer,
    ERC20_transferFrom
)
