Sway is a language developed for the Fuel blockchain. It is heavily inspired by Rust and aims to bring modern language development and performance to the blockchain ecosystem.
For user documentation, including installing release builds, see the Sway Book: https://fuellabs.github.io/sway/latest/.
This section is for developing the Sway compiler and toolchain. For developing contracts and using Sway, see the above documentation section.
Sway is built in Rust. To begin, install the Rust toolchain following instructions at https://www.rust-lang.org/tools/install. Then configure your Rust toolchain to use Rust stable
:
rustup default stable
If not already done, add the Cargo bin directory to your PATH
by adding the following line to ~/.profile
and restarting the shell session.
export PATH="${HOME}/.cargo/bin:${PATH}"
To ensure access to all dependent repositories, create and add SSH keys to your GitHub account.
Clone the repository and build the Sway toolchain:
git clone [email protected]:FuelLabs/sway.git
cd sway
cargo build
Confirm the Sway toolchain built successfully:
cargo run --bin forc -- --help
To run forc
from any directory, install forc
to your local Cargo bin directory:
cargo install --locked --path forc
