[!NOTE] This project never came to fruition, but it'll return for TASBox in my wiremod replacement.
It's already much further along than Expressive was.
Keep an eye on https://github.com/mekkanics :)

Expressive

Expression, but it's Typescript with extras

Expressive is the hopeful final solution to the Expression programming languages. It was originally a fork of Expression3, but has become a full rewrite. It is modeled after Typescript.

Note

This is a work in progress. Adding this to the server may be dangerous. And yes this is codenamed Expression4.

This could potentially give players access to serverside lua. Yes. It's that bad.

Differences from E2

Practically everything. There are classes, you can finally make lowercase variables, lambdas, and whatnot. Everything is neatly in libraries, like holograms.create

This also leverages the powerful Syper editor instead of the wire editor, which comes with autocomplete, "intellisense", code folding, custom themes and more.

<!-- TODO List of stuff here -->

Example Code

// You can create lowercased variables now.
// 'var' creates a global variable. It does not follow javascript/ts convention as function scoping is really horrible anyway.
var ops = 55;
ops++;
ops--;

// New function definitions typescript style.
// Note that despite this example having a lack of explicit type annotations, this is a *strictly* typed language.
// The types are inferred by the compiler.
function bar(foo: int, bar: int) {
	return foo + bar;
};

// This is not a part of typescript, and custom to Expressive.
// These are expression blocks, which allow you to block your code into scopes for organization.
// You can get the return value out of the last expression in the scope through implicit returns.
{
	var global = 55;
	let str = "🤖";

	{
		// Boolean values!
		let anotherone = true;
		{
			// Typed builtin array types. No more array()[1, number]
			// Every value inside of it must be the same type.
			let an_array = ["Hi"];
		}
		// 'str' also exists in here

		// 'anotherone' is dropped.
	}
	// 'global' exists in here
	print(global)
}
// 'global' exists cause it uses 'var', which defines a global variable
print(global);
// print(str); -- Errors, 'str' is only defined inside of the above scope.
