moonscript VS TypeScriptToLua

Now I like lua, and think single pass is the way to go for interpreted, since you don't have the disadvantage of a slow compile time no matter how big your codebase gets, BUT its not great to write in. things like +=, ++, are not possible, which means the only solution is to transpile into it, which has led to some good languages like moonscript[0], teal[1] which offers static type checking, an absolute must as your codebase grows.

That can be very productive and clever, but be - and stay - aware that such polyglot solutions tend to be maintenance headaches in the longer run.

There is a really nice open source project out there that allows you to train your hearing and your sightreading, but it's written in the authors own language which in turn compiles to JavaScript and the headache to set up their toolchain is such that I haven't bothered fixing any of the bugs that I'm aware of (and there are plenty).

It's written in a language called 'Moonscript':

Which compiles to Lua. Which compiles to JS.

Madness. Nice madness, but still, it stopped me from being a contributor.

RE: the cost of switching at this point, what about languages that compile to Lua? Like https://moonscript.org/. That would let you keep the legacy code, no?

In the case of Lapis, it is actually written in Moonscript, which needs a few more things.

There's also some languages made to compile straight to Lua: - MoonScript is the most popular Lua wrapper - it's built to be more Python-like, featuring indentation-based scopes, function calls without parentheses, lambda syntax, list comprehension, and much more. - Yuescript is a modern update to MoonScript that adds more features (I haven't used it myself, so I'm not entirely sure exactly how it differs from MS). - Teal is a version of Lua that adds static typing for better code standards.

A programmer-friendly language that compiles to Lua.

This is a sample code for learning, written in Moonscript for TIC-80:

I've had some success with https://github.com/TypeScriptToLua/TypeScriptToLua

Luau may be an alternative as well, haven't tried it.

I love Lua, but at larger scales it's unmanageable.

There are some plugins (typescript.nvim) that use a Typescript to lua transpiler (TypescriptToLua]

54:28 reminded me of TypeScriptToLua, so if you wanted to, then you could turn this into Lua :^)

One immediate comparison that springs to my mind is the Löve 2D engine [1], which is a tiny game engine written entirely around Lua scripting (so that Lua includes the full game run loop as well).

Lua is a good scripting language, but it doesn't have the ubiquity of JS (and Löve doesn't have the ubiquitous deployment of the modern browser). Also, Lua doesn't have a static type ecosystem (though there are interesting projects like TypescriptToLua [2] exploring that space, but you can from the name they are following/lagging the JS ecosystem here).

There probably is a need to package more browser games as "real" games and a lightweight Canvas-focused approach could find a nice like Löve, especially if it were easier, for instance, to maybe port to consoles for small/indie game teams than one of the web views or Electron. (Though certainly Microsoft already has a version of WebView2 running on the Xbox.)

Not part of the mods, but using https://github.com/TypeScriptToLua/TypeScriptToLua is quite easy and works surprisingly well. You can find some of the type definitions for computercraft here: https://github.com/Eforen/cc-tweaked-types/tree/master/declarations

It might be helpful to keep in mind: Typescript is a compiler that parses a Typescript AST and prints out whatever you want. So if your goal is to use it in a JS context, the only thing regulating what you do with it is that it outputs valid JS that can be interpreted by the various JS engines. There are projects like TypeScriptToLua which uses the TS compiler to print out Lua code.

You can take a look at TypescriptToLua which transforms the TS AST into Lua code using the compiler API, however I think you're barking up the wrong tree. The TS compiler works on *it's own\* AST generated from parsed Typescript. You can see how they implement your own type here. What you have some structured data and want to turn it into a type definition. That's just some loops you write yourself over data you've hopefully structured in a sane way. Turn it into a string, write it to a file with the extension `.d.ts`. No libraries needed.
