catala/french_law

French Law Libraries

This folder presents a working example of how Catala could be distributed and deployed inside existing applications. Each sub-folder is specialized for a particular programming language, and features a ready-to-use library of all the French public algorithms coded up using Catala so far.

Pre-built artifacts for the OCaml, JS and Python backends are available at https://catalalang.github.io/catala/ ; they are automatically updated to follow the latest updates of the development version of Catala (master branch).

General principles

Let us say you want to deploy a Catala program inside an application written in programming language X. The Catala compiler will translate the source Catala program into X, yielding a new .x source code file. This .x file will export functions corresponding to the scopes of the original Catala program. You can then reuse those exported functions in your application written in X.
