Yuescript VS tl

I'm a big fan of moonscript, but occasionally wish it was still be improved and worked on. Yuescript¹ looks like it fixes most of my bugbears with moonscript, and it is largely a faster² drop-in replacement.

There was s little discussion here ~18 months ago³, but it will largely circular if you look as people are suggesting fennel there ;)

² This probably only matters if you have tonnes of moonscript, not just a little neovim/mpv/awesomewm config or something.

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.

Yes, this is unfortunately true.

There's a spiritual successor: https://yuescript.org/

Yuescript in yellow

What I didn't know about is that its fork YueScript is actively maintained, and with some extra features.

I've put together a Lua config with Neovim, but it was still kind of obnoxious to put together. Lua isn't that great of a language, because people seem to forget it's an embed-able language for a reason (it's not supposed to give you tons of features). Using something that makes some of your more complex problems easier like Moonscript or Yuescript can make things more complex in regards to your configuration.

it's based off MIR, does it have something to do with https://mlir.llvm.org/ ?

for typed lua, there is another effort https://github.com/teal-language/tl in addition to the mentioned typescript approach: https://github.com/andremm/typedlua

I had the pleasure of working with Lua 5.1 back in the late noughties. For me it's replaced Tcl whenever I want something I can configure above a C library. At the time I used it I found it quite nice but I'll also not forget the hours I wasted tracking down nil table corruptions which could have easily been caught by a type checker.

I had some hope that Luau https://luau-lang.org or Teal https://github.com/teal-language/tl would make things better but with the following example

    function foo(x: number): string

I wonder why the author doesn't use Teal [0] - a typed dialect of lua.

Check out Teal

There is already https://github.com/teal-language/tl, which is typed Lua. I think fennel exists to serve a different niche-- personally I use it not for any type features; I just like the syntax better, and others may find certain features like the macro system useful.

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.

Terra and Nelua are both very different in goals than Teal. Teal is literally gradual types integrated into Lua keeping as many of Lua's idioms as possible (to a fault[1]). Terra and Nelua are both very metaprogrammable systems programming languages. Nelua's goals are primarily to soften C's rough edges, comparable to something like Nim.

There's another one you missed in Pallene[2]. But again, it's goal was to optimize the stack sharing involved in using the C API. It also adds types though and maintains Lua idioms as much as possible.
