Wish Solidity had more concise array initialisation?

Solarray is a blazing-fast helper library for convenient Solidity dynamic arrays. Useful for writing foundry test cases that involve arrays.

uint8[] memory nums = Solarray.uint8s(1, 2, 3);
address[] memory tokens = Solarray.addresses(address(0), address(1));

Supports 1-8 arguments for most of the common types.

forge install evmcheb/solarray

import {Solarray} from "solarray/Solarray.sol";

If you want to include a new type, you can use the generator.py script that I used to make the helper library.
