# Foundry development framework Vulcan launches v0.1

Source: https://github.com/nomoixyz/vulcan

## Summary

Vulcan, a development framework for Foundry projects focused on developer experience and readability, has released v0.1, which is built on top of forge-std. The README says it initially offers functionality similar to forge's VM and forge-std, with plans to grow into a feature-rich framework. Stated goals include better naming for VM functionality, a testing framework with a familiar syntax, improved ergonomics, and out-of-the-box Huff language support. Planned features are a mocking framework and a deployment management framework. The README also warns that the project is not actively maintained.

Development framework for Foundry projects, with a focus on developer experience and readability.

Built on top of forge-std ❤️

Initially, Vulcan will provide functionality similar to what is already included in forge's VM and forge-std.

Over time, Vulcan will grow to include more functionality and utilities, eventually becoming a feature-rich development framework.

Installation

Install the latest release by running:

$ forge install nomoixyz/vulcan

Or install a specific release with:

$ forge install nomoixyz/vulcan@x.y.z

Release tags can be found here

Usage

See the Vulcan Book for detailed usage information.

Why Vulcan?

Our goal is to provide:

Better naming for VM functionality (no more prank, roll, warp, ...)

A testing framework with better readability and a familiar syntax

Improved ergonomics

Huff language support out of the box

Vulcan test example:

import { Test, expect, commands, Command, CommandResult, println } from "vulcan/test.sol"; contract TestSomething is Test { function testSomething() external { // Format strings with rust-like syntax println("Hello {s}", abi.encode("world!")); // Hello world! // Format numbers as decimals println("Balance: {u:d18}", abi.encode(1e17)); // Balance: 0.1 // Nice external command API! Command memory ping = commands.create("ping").args(["-c", "1"]); CommandResult pingResult = ping.arg("etherscan.io").run(); // Rust-like results bytes memory pingOutput = pingResult.expect("Ping command failed").stdout; println("Ping result: {s}", abi.encode(pingOutput)); // Expect style assertions! expect(pingResult.isError()).toBeFalse(); expect(pingResult.isOk()).toBeTrue(); // And much more! } }

Planned Features

Mocking framework

Deployment management framework

Contributing

At this stage we are looking for all kinds of feedback, as the general direction of the project is not fully defined yet. If you have any ideas to improve naming, ergonomics, or anything else, please open an issue or a PR.
