foundry-abi-tools

When writing client applications for smart contracts it's useful to be able to aggregate all the necessary details out of the ABI. ABIs have a ton of information, and usually we just care about events, functions, and their parameters. This library provides a simple interface for extracting that information.

This is built to work with Foundry - poorly - but it works.

Installation

npm install --save-dev foundry-abi-tools

Usage

➜ cd <into root of current forge project, with forge.toml>
➜ forge build
➜  abitools
? Please choose which job to use (Use arrow keys)
❯ log 
  codegen 

Important: currently only LOG is supported.

you can also just run:

abitools log

Options

coming soon, maybe, got some started but realistically this is a one-off tool for now.

Example Output

There is color-coding in the console that doesn't show up here.

------------------------------------------------------
Logging events and functions for: TestToken
------------------------------------------------------
Events:
        Approval(address, address, uint256)
        Transfer(address, address, uint256)
Functions:
        allowance(address, address)
        approve(address, uint256)
        balanceOf(address)
        decimals()
        decreaseAllowance(address, uint256)
        increaseAllowance(address, uint256)
        name()
        symbol()
        totalSupply()
        transfer(address, uint256)
        transferFrom(address, address, uint256)

Description

this CLI will load up your forge.toml to grab your src and out directory locations. It will iterate through all files in the src folder, and then grab the abis out of the out location.

From this, it will extract all the events and functions out of the different contracts, and then the toolstack can do stuff with that information.
