The Fuel Toolchain

The Fuel toolchain consists of several components.

Forc (forc)

The "Fuel Orchestrator" Forc is our equivalent of Rust's Cargo. It is the primary entry point for creating, building, testing, and deploying Sway projects.

Sway Language Server (forc-lsp)

The Sway Language Server forc-lsp is provided to expose features to IDEs. Installation instructions.

Currently, only Visual Studio Code is supported through a plugin. Vim support is forthcoming, though syntax highlighting is provided.

Note: There is no need to manually run forc-lsp (the plugin will automatically start it), however both forc and forc-lsp must be in your $PATH. To check if forc is in your $PATH, type forc --help in your terminal.

Sway Formatter (forc-fmt)

A canonical formatter is provided with forc-fmt. Installation instructions. It can be run manually with

forc fmt

The Visual Studio Code plugin will automatically format Sway files with forc-fmt on save.

Fuel Core (fuel-core)

An implementation of the Fuel protocol, Fuel Core, is provided together with the Sway toolchain to form the Fuel toolchain. The Rust SDK will automatically start and stop an instance of the node during tests, so there is no need to manually run a node unless using Forc directly without the SDK.
