file? UpdateREADME`?src/catala/default_calculus/interpreter.mlusesrc/catala/runtime.mlfunctions to avoid duplication?Overview
This PR adds an OCaml backend to the Catala compiler. The starting point is the default calculus representation, which is lowered into a lambda calculus (
src/catala/lambda_calculusfolder) with exceptions according to a compilation scheme described in a new section of the formalization PDF.The lambda calculus is then translated to OCaml syntax in the
src/catala/lambda_calculus/to_ocaml.mlfile. This OCaml backend is used to create a new OCaml library,french_law, containing for now only the Allocations familiales computatation. A machinery is set up to export this library to JS using JS_of_ocaml and a wrapper that exposes a convenient signature when you just call the function with a JSON object describing all the inputs. The OCaml backend through the replication of the unit tests of the Allocations familiales example.
