Requirements

Prerequisites and/or dependencies that this project needs to function properly

Node JS and NPM, or similar Node JS package manager, is required to utilize this project and dependencies.

---

Quick Start

Perhaps as easy as one, 2.0,...

Install project globally...

npm install --global @solidity-utilities/abi-to-interface

Available CLI parameters may be listed via --help option...

solidity-abi-to-interface --help

---

Note, if solidity-abi-to-interface reports errors similar to...

bash: solidity-abi-to-interface: command not found

... then please ensure the PATH variable includes a reference to the NPM prefixed bin/ directory, eg.

# Add prefix if not defined
grep -qE '^prefix ' <(npm config ls) || {
  tee -a "${HOME}/.npmrc" 1>/dev/null <<EOF
prefix = "${HOME}/.npm"
EOF
}


# Append to PATH variable if not defined
_npm_prefix="$(awk '/^prefix / {
  gsub("\"", "");
  print $3;
}' <(npm config ls))"

grep -qE "(:)?(${_npm_prefix}/bin)(:)?" <<<"${PATH}" || {
  tee -a "${HOME}/.bashrc" 1>/dev/null <<EOF
export PATH="${PATH}:${_npm_prefix}/bin"
EOF
}


# Reload Bash RC file
source "${HOME}/.bashrc"

Usage

How to utilize this repository

Change current working directory to a Solidity project...

cd ~/git/hub/solidity-utilities/example

Compile contract(s) into ABI JSON file(s)...

truffle compile

Generate an interface contract based on Account contract ABI...

solidity-abi-to-interface --abi build/contracts/Account.json\
                          --out contracts/InterfaceAccount.sol

---

A source contract such as...

contracts/Account.sol

// SPDX-License-Identifier: AGPL-3.0
pragma solidity 0.8.7;

contract Account {
    string public name;
    address payable public owner;

    function updateName(string calldata _new_name) external {
        require(msg.sender == owner, "Owner required");
        name = _new_name;
    }
}

Will result in an interface similar to...

contracts/InterfaceAccount.sol

// SPDX-License-Identifier: AGPL-3.0
pragma solidity 0.8.7;

/// @title Automatically generated by `@solidity-utilities/abi-to-interface`
interface InterfaceAccount {
    /* Variable getters */

    function name() external view returns (string memory);

    function owner() external view returns (address payable);

    /* Function definitions */

    function updateName(string calldata _new_name) external;
}
