I have an application written in OCaml that I'm interested in porting
over to Haskell, and I was wondering what the best way to replace the
following OCaml function would be:
Toploop.initialize_toplevel_env();;
let eval txt = let lb = (Lexing.from_string txt) in
let phr = !Toploop.parse_toplevel_phrase lb in
Toploop.execute_phrase true Format.std_formatter phr;;
eval "let add1 x = x +1;;";;
eval "add1 2;;";;
Where I would like to be able to "eval" Haskell-code instead. It looks
like I might be able to achieve something like this using hs-plugins,
but it looks a bit more complex. Is hs-plugins the best choice for this
kind of "meta"-programming? I'm pretty sure Template Haskell will not
work for me, at least as I understand it I can only manipulate program
fragments that will be compiled later and as such that it will not be
possible to execute them until the next "phase".
