Installing the command-line executable

Assuming you have Rust/Cargo installed, run this command in a terminal:

cargo install cairo-size-profiler

It will make the cairo-size-profiler command available in your PATH if you've allowed the PATH to be modified when installing Rust. cargo uninstall cairo-size-profiler uninstalls.

Back to the crate overview.

About

Cairo is the first Turing-complete language for creating provable programs for general computation.

Getting Started

Prerequisites

Install Rust
Set up Rust:

rustup override set stable && rustup update

Ensure Rust was installed correctly by running the following from the root project directory:

cargo test

Compiling and running Cairo files

Compile Cairo to Sierra:

cargo run --bin cairo-compile -- --single-file /path/to/input.cairo /path/to/output.sierra --replace-ids

Compile Sierra to casm (Cairo assembly):

cargo run --bin sierra-compile -- /path/to/input.sierra /path/to/output.casm

Run Cairo code directly:

cargo run --bin cairo-run -- --single-file /path/to/file.cairo

See more information here. You can also find Cairo examples in the examples directory.

For running tests specifically, see here: cairo-test

Compiling Starknet Contracts

Compile a Starknet Contract to a Sierra ContractClass:

cargo run --bin starknet-compile -- --single-file /path/to/input.cairo /path/to/output.json

Or specify the contract path if multiple contracts are defined in the same project:

cargo run --bin starknet-compile -- /path/to/input/crate /path/to/output.json --contract-path path::to::contract

Compile a Sierra ContractClass to a CASM CompiledClass:

cargo run --bin starknet-sierra-compile -- /path/to/input.json /path/to/output.casm

Roadmap

The next milestone is to reach feature parity with the old Cairo version. You can track the exact progress here.
