Environment Setup

💡 Info This tutorial is only relevant if you wish to contribute to Starknet Foundry. If you plan to only use it as a tool for your project, you can skip this part.

Prerequisites

Rust

Install the latest stable Rust version. If you already have Rust installed make sure to upgrade it by running

$ rustup update

Scarb

You can read more about installing Scarb here.

Please make sure you're using Scarb installed via asdf - otherwise some tests may fail.

To verify, run:

$ which scarb

the result of which should be:

$HOME/.asdf/shims/scarb

If you previously installed scarb using an official installer, you may need to remove this installation or modify your PATH to make sure asdf installed one is always used.

cairo-profiler

You can read more about installing cairo-profiler here.

❗️ Warning

If you haven't pushed your branch to the remote yet (you've been working only locally), two tests will fail:

• e2e::running::init_new_project_test
• e2e::running::simple_package_with_git_dependency

After pushing the branch to the remote, those tests should pass.

Starknet Devnet

To install it run ./scripts/install_devnet.sh

Universal sierra compiler

Install the latest universal-sierra-compiler version.

Running Tests

Tests can be run with:

$ cargo test

Formatting and Lints

Starknet Foundry uses rustfmt for formatting. You can run the formatter with

$ cargo fmt

For linting, it uses clippy. You can run it with this command:

$ cargo clippy --all-targets --all-features -- --no-deps -W clippy::pedantic -A clippy::missing_errors_doc -A clippy::missing_panics_doc -A clippy::default_trait_access

Or using our defined alias

$ cargo lint

Spelling

Starknet Foundry uses typos for spelling checks.

You can run the checker with

$ typos

Some typos can be automatically fixed by running

$ typos -w
