# My local copy of OCaml MiniPy

A Naive (OCaml) interpreter for a (minimalist subset of a) Python like language.

Try the [interpreter](console.html) online or use the [editor](editor.html) (these rely on [js_of_ocaml](https://ocsigen.org/js_of_ocaml/3.5.1/manual/overview)).

This is a work in progress, most of the supported features are only partially implemented.

## Screenshots

Here is an example of using the [MiniPy OCaml console](https://perso.crans.org/besson/publis/MiniPy/console.html), to define a `sum` function. It shows that a lot of basic construct of the Python language are supported, but almost no functions from the standard library are available:

Here is a second example, using the [MiniPy OCaml editor](https://perso.crans.org/besson/publis/MiniPy/editor.html), loaded with one of the example files, showing a Eratosthene Sieve to detect prime numbers:

Here is a third and last example, using the [MiniPy OCaml editor](https://perso.crans.org/besson/publis/MiniPy/editor.html), loaded with one of the example files, showing the prime decompositions of integers. I added a few comments (`# blabla`) to show some features supported by MiniPy:
