Quick Start

Ape compiler plugin around the Starknet Cairo language.

Dependencies

• python3 version 3.8 up to 3.11.

Requirements

• (Recommended) If you have Scarb project, please install Scarb .

  # Install via quick installation script
  curl --proto '=https' --tlsv1.2 -sSf https://docs.swmansion.com/scarb/install.sh | sh
  

  or

  # Install via asdf version manager
  asdf plugin add scarb
  asdf install scarb latest
  asdf global scarb latest
  

• If you have a single Cairo contract or a package that defines cairo_project.toml file, please install Cairo

  First, you need to install Rust. You can do this by running the following command:

  rustup override set stable && rustup update
  

  Then, you can install Cairo by running the following command:

  git clone https://github.com/starkware-libs/cairo my/cairo/path
  

Installation

via pip

You can install the latest release via pip:

pip install ape-cairo

via setuptools

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

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

Quick Usage

ape-cairo can compile,

• Scarb projects
• Single Cairo contracts
• Packages (crates) that define cairo_project.toml file.

✿ Scarb Projects

Scarb binary is required to compile Scarb projects. Please add it to your $PATH if you have not done so.

Now, when compiling, Ape will use the command scarb build. You can specify the Scarb manifest file (Scarb.toml) in your ape-config.yaml file:

cairo:
  scarb_manifest: /Users/home/path/to/scarb/project/Scarb.toml

❂ Other Cairo Projects

Cairo compiler binaries are required to compile other Cairo projects.

Please add them to your $PATH. You can verify them by doing:

which sierra-compile

and

which starknet-compile

or you can specify the Cairo manifest path in your ape-config.yaml file:

cairo:
  cairo_manifest: /Users/home/path/to/cairo/Cargo.toml

If you have a package that defines cairo_project.toml file, you can also specify the package manifest path in your ape-config.yaml file, if it is not in the directory where ape-config.yaml is located.

cairo:
  package_manifest: /Users/home/path/to/package/cairo_project.toml

★ Using the Compiler

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

ape compile

It should compile your Cairo contracts. You can find the compiled contract artifacts (Sierra/Casm) in the .build/ folder.

You can also get debug outputs by running the command with the --debug flag.

ape compile -v DEBUG

Manage Cairo Project Dependencies

ape-cairo can manage your Cairo project dependencies. See Ape documentation. But, it is recommended to use Scarb for managing dependencies in Scarb projects.

Ape Config Parameters

• dependencies: A list of dependencies that the project depends on. Optional.
• cairo_manifest: The path to the Cairo compiler manifest file. Required if you didn't add binaries (sierra-compile, starknet-compile) to your $PATH.
• scarb_manifest: The path to the Scarb project manifest file. Required if you are compiling a Scarb project.
• package_manifest: The path to the package manifest file that defines the Cairo project. Required if you are compiling multiple Cairo contracts in a package and the manifest file is not in the directory where ape-config.yaml is located.
