Web3 Extension for Zed

This extension adds support for Web3 development in the Zed editor, with primary focus on:

• Solidity language support
• Hardhat framework integration
• Foundry framework integration

Features

Solidity Language Support

• Syntax highlighting for Solidity (.sol) files
• Code navigation
• Smart code completion
• Auto-indentation
• Bracket matching
• Code outline/structure view
• Vim textobjects support

Hardhat Integration

• Automatic detection of Hardhat projects
• Language server integration with hardhat-language-server
• Recognition of hardhat.config.js and hardhat.config.ts files

Foundry Integration

• Automatic detection of Foundry projects
• Language server integration with nomicfoundation-solidity-language-server
• Recognition of foundry.toml configuration files

Installation

From Zed Extension Registry

1. Open Zed
2. Open the extensions view (Cmd+Shift+E or Ctrl+Shift+E)
3. Search for "Web3"
4. Click "Install"

As Dev Extension

1. Clone this repository

git clone https://github.com/your-username/web3-zed.git

2. Open Zed
3. Open the extensions view (Cmd+Shift+E or Ctrl+Shift+E)
4. Click "Install Dev Extension"
5. Select the cloned repository directory

Prerequisites

To fully utilize this extension, you should have:

1. Node.js and npm installed for running the language servers
2. For Hardhat projects: Install hardhat in your project (npm install --save-dev hardhat)
3. For Foundry projects: Install Foundry according to the official documentation

Language Server Configuration

This extension will automatically:

• Detect if your project is a Hardhat project (by checking for hardhat.config.js or hardhat.config.ts)
• Detect if your project is a Foundry project (by checking for foundry.toml)
• Use the appropriate language server based on the detected framework

If neither is detected, it will default to the Nomicfoundation Solidity Language Server.

💡 Solidity Snippets

The snippets/solidity.json file provides intelligent code templates for faster Solidity development with Foundry/Hardhat integration. Trigger these with prefix commands in Zed.

🏗️ Core Templates

Prefix	Description	Use Case
erc20	Complete ERC20 token implementation	Token contracts
nonreentrant	Reentrancy protection wrapper	Secure function patterns
modifier	Access control modifier	Owner/role restrictions
error	Custom error definition	Gas-efficient reverts

🧪 Testing Snippets

Prefix	Description	Framework
foundry-test	Foundry test contract with setup	Unit/Integration tests
fuzz	Fuzz testing template	Property-based testing

🔧 Utility Snippets

Prefix	Description	Output Example
natspec	Complete NatSpec documentation	@dev technical notes
safecheck	Input validation with custom error	if (x==0) revert Error()
event	Event definition + emission	emit Transfer(...)

⚙️ Deployment

Prefix	Description	Framework
hh-deploy	Hardhat deployment script	Scripts/deploy.js

✨ Key Features

• Framework-aware: Dedicated snippets for Foundry/Hardhat workflows
• Security-first: Auto-includes best practices (reentrancy guards, input validation)
• Interactive placeholders: Tab through fields with intelligent defaults
• Documentation-ready: NatSpec templates with all standard tags

Usage: Type any prefix in Zed editor and press Tab to expand.
