Foundry Language Template

A Foundry template to compile and test smart contracts in various EVM languages, including Solidity, Yul, Vyper, Huff and pure Bytecode.

Installation / Setup

In order to compile Vyper and Huff contracts, make sure you have the respective compilers installed:

• Vyper
• Huff

Then clone this repo and install the dependencies:

git clone https://github.com/beskay/foundry-lang-template.git
cd forge-lang-template
forge install

Now you are all set up and ready to go!

Testing

The usage is demonstrated by the standard Counter contract, which is implemented in all supported languages.

Counter.sol:

forge test --mc CounterTestSol --ffi

Counter.yul:

forge test --mc CounterTestYul --ffi

Counter.vy:

forge test --mc CounterTestVy --ffi

Counter.huff:

forge test --mc CounterTestHuff --ffi

To test the pure bytecode implementation, you have to set the BYTECODE environment variable first, e.g.:

export BYTECODE=0x604680600c6000396000f3fe6000803560e01c80633fb5c1cb14603d578063d09de08a1460325763f2c9ecd81460265780fd5b60209054604051908152f35b506001815401815580f35b50600435815580f3

forge test --mc CounterTestBase
