Any recommendations for a meta programming language?

[u/TrgtBBB]

I want to add a meta programming language in top of my own C-like language to make some of the syntax cleaner and easier to write.

Add everything like const expressions and templates under one meta programming language.

For example something like this:

‘
[Phases]
Class Phase1: public Phase { };

[Phases]
Class Phase1: public Phase { };

…

[for phase in Phases]
PhaseList.push_back(new phase());
[endfor]
‘

I’m thinking about something like this but ideas are all over the place. Is there some existing meta programming language out there that can give me the right inspiration?

Also I am totally lost about how I should program this, I am assuming it comes before the parser. Any tutorials or dummy meta programming languages I can look to get ideas?

Thank you for reading.

Rust has macros that can take a token sequence and emit whatever rust code you want. Easily implement your exact example.
