@mattsse can you provide some more context of these features here?

[mattsse]

here are some docs/instructions

https://github.com/foundry-rs/foundry/blob/master/docs/dev/cheatcodes.md#cheatcodes-implementation

what we want is something like:

function toLowercase(string) returns string

the rust cheatcode then simply returns .to_lowercase()

see EnvBool cheatcode for example:

foundry/crates/cheatcodes/spec/src/vm.rs

Lines 844 to 847 in 6b2633c

	/// Gets the environment variable `name` and parses it as `bool`.
	/// Reverts if the variable was not found or could not be parsed.
	#[cheatcode(group = Environment)]
	function envBool(string calldata name) external view returns (bool value);

foundry/crates/cheatcodes/src/env.rs

Lines 27 to 32 in 6b2633c

	impl Cheatcode for envBool_0Call {
	fn apply(&self, _state: &mut Cheatcodes) -> Result {
	let Self { name } = self;
	env(name, &DynSolType::Bool)
	}
	}

Are you currently working on this @1010adigupta? I find it interesting and would like to work on it especially after the great guide from @mattsse

[bolajahmad]

@mattsse a few questions, for the native string utils are you suggesting adding the following and any other suggestions?
replace, lowercase, uppercase, trim, split

Implementing the string to the respective cheat code and returning the response, will that suffice to close this issue?

[1010adigupta]

yes currently working on it :)

yes, I guess we also want these:

[1010adigupta]

In what group should these Utils go?
string, env, or utilities?

[1010adigupta]

Hey @mattsse I have created a pr for string utils of lowercase, uppercase, trim, replace, split if that's lgtm you can merge it

yes, I guess we also want these:

https://github.com/OpenZeppelin/openzeppelin-contracts/blob/master/contracts/utils/Strings.sol

I will start working on these with a new pr
I think we would need to add the following:
toHexString and toStringSigned
