you might want to borrow some idea from terra, see [1] for a simple example.

imho, LLVM's API is, by definition, too low-level. I don't think I would like
to write a compiler in Lua using such low level API. I just can't keep
the contexts in mind. I'd rather deal with things like AST or similar.

I'm very interested in the idea of terra.

terra has a simple yet flexible syntax design. it is very much like Lua, with
some straightforward extensions like static type annotation. terra is mixed
with Lua. a keyword `terra` is used to switch the context.

what's most interesting is that Lua can be regard as the meta-language of terra.
a terra function is just a Lua value. you can manipulate the AST in Lua.
in addition, terra also has quotes and escapes, making meta-programming easy.

terra also has the interoperability with C. you can import definitions directly
from C header files.
