Using github and gradle plugins I metaprogramm java. Can't recommend it through. It's extremely error prone and hard to reason about.

I'd like to say I'm a huge fan of Julia, and don't have much experience with metaprogramming in other languages.
I'm sure I do more of this than necessary, but much of my code ends up being "generated functions".
@generated foo(x, y) ... end
When you write an `@generated` function, you write code that creates a Julia expression. Using "x" and "y" in the function give you the types of these arguments. Defining parametric structs lets you pass any information you want (eg, array sizes) to specialize code and algorithms.
A very useful library: https://github.com/MikeInnes/MacroTools.jl

I came here to say Julia as well!
I didn’t really understand or get the point of metaprogramming, but the more Julia I’ve been writing the more I’ve seen fantastic uses of it and the more inspired I get.
Plus the language itself is a real pleasure to write.

Mike Innes produces so many cool Julia libraries!
Flux is easily the coolest ML framework I’ve used, and I’ve just discovered Lazy.jl.

#37> Ruby is notably absent as I use it and am looking for something better/different
what issues do you have with ruby? it's the de-facto standard for meta-programming
I often use things like `define_method`, `constants`, `method_missing`, etc in select places.
last fun thing I did was adding `let` and `it` to rails's tests.

#38It's worth to mention Factor programming language - https://factorcode.org/
https://en.wikipedia.org/wiki/Factor_(programming_language)
https://github.com/factor/factor/
http://andreaferretti.github.io/factor-tutorial/ - Good introduction and Metaprogramming section.

#39Earlier quoted context omitted.
Compile-time MP and run-time MP. Support for AST and quasi-quote MP, and support for LMS (= lightweight modular staging).
You haven't seen any Lisp yet, have you? Compile and run-time MP and quasiquoting are basic features; I'd argue that a language without these doesn't even qualify as "supporting metaprogramming".
Sure, I'm intimately familiar with the Lisp family of languages. It lacks features that I prefer in a modern meta-programming language, in particular an expressive typing system with type inference, and a platform / eco-system like the JVM.

#40I am surprised nobody has mentioned C++
I know its hated passionately, but I learned about metaprogramming from it.
Also, imo, Racket is the best language for metaprogramming.
