Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Ask HN: Parrot language copycat my Gravity source code. What can I do?
I found out that the Parrot programming language (https://github.com/parrot-language/parrot) did copycat line by line my Gravity programming language (https://github.com/marcobambini/gravity).
I know that I used a very permissive license and that the project can be forked and modified by anyone but this is a theft more than a fork.
What can I do in this situation?
- When does garbage collector start in Gravity?
- Binding a Language to Gravity

Lua's Lack of “Batteries”
This is gonna be subjective, because it depends on what your priorities are.
The two alternatives at the top of my list are Gravity and Wren. They are both designed for the same general profile that Lua has—a scripting language, safe to use, embeddable, with a small VM (low code size).

- https://wren.io/
The language design choices are nice and familiar to people who are used to other existing languages. Lua is a bit radical.
Two other options are AngelScript and Squirrel, which are both a bit older and more mature than Gravity and Wren. In my opinion they are

- http://squirrel-lang.org/
Finally, it’s much more feasible these days to embed something like Mono, and Guile has gotten a lot better.

LuaX: A Lua Dialect with JSX
It would have been nice if LuaX was written in Lua.
Forking Pallene (https://github.com/pallene-lang/pallene) would introduce:
- Which for loop method is faster
- Using Lua with C++

Bog – small, strongly typed, embeddable language
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.

Nelua, AOT statically typed Lua
That was somewhat of an entertaining read.
> Terra is C if you replaced the preprocessor with Lua.
This is what is written on the tin.
PUC made there own version of Terra

This is a good writeup on all the Alt-Luas https://injuly.in/blog/gsoc/
- data types in function definition
- You can make Lua compiled/statically typed using Teal... It's like TypeScript, but for Lua!

Lua, a Misunderstood Language
Odd to suggest that if they're interested in Lua, that they should check out Moonscript which is a different language altogether (although it compiles to Lua). But if you insist, something a little more Lua-ish is Teal[1] (gradual types ala TypeScript) or Pallene[2] (companion typed subset of Lua meant to generate optimized C libraries for use with Lua).
