Solidity LSP

Solidity language server integration providing comprehensive smart contract development support through solc (Solidity compiler) and solhint (linter).

Capabilities

Compilation: Compile Solidity smart contracts with solc
Linting: Static analysis with solhint for best practices and security
Security: Detect common vulnerabilities (reentrancy, overflow, etc.)
Gas optimization: Identify expensive operations
Code intelligence: Syntax highlighting, error detection
Supported extensions: .sol

Installation

Install Solidity compiler and linter:

bash

# Solidity compiler
npm install -g solc

# Solidity linter
npm install -g solhint

Verify installation:

bash

solcjs --version
solhint --version

Usage

Compile Solidity Contract

bash

solcjs --bin --abi contract.sol

Compile with optimization:

bash

solcjs --optimize --bin --abi contract.sol

Lint Contract

Run solhint on a file:

bash

solhint contracts/MyContract.sol

Run on entire project:

bash

solhint 'contracts/**/*.sol'

Security Analysis

solhint includes security rules by default. For advanced security analysis, consider:

bash

# Install slither (requires Python)
pip3 install slither-analyzer

# Run security analysis
slither contracts/

Configuration

solhint Configuration

Create .solhint.json in project root:

json

{
  "extends": "solhint:recommended",
  "rules": {
    "compiler-version": ["error", "^0.8.0"],
    "func-visibility": ["warn", {"ignoreConstructors": true}],
    "max-line-length": ["warn", 120],
    "not-rely-on-time": "warn",
    "avoid-low-level-calls": "warn",
    "no-inline-assembly": "warn"
  }
}

Hardhat/Foundry Integration

For full development environments, see references/frameworks.md.

Integration Pattern

When developing smart contracts:

Write: Edit Solidity code
Lint: Run solhint to catch issues early
Compile: Use solcjs to verify compilation
Analyze: Run security tools before deployment
Test: Write comprehensive unit tests

Common Issues

Compiler version mismatch: Specify pragma version in contract
Gas optimization: Use view/pure where possible
Security: Never use tx.origin for authentication
Best practices: Follow Checks-Effects-Interactions pattern

## Usage

### Compile Solidity Contract

solcjs --optimize --bin --abi contract.sol
