Create novel Scheme-like DSL(isp)s using Python.

It has nothing to do with the MyPy or Hy projects.

A Python file is the "source code" for your DSL.

The Lisp class is the entry point for creating DSLs. It provides an API for creating Lisp-y constructs.

# my_lisp.py
from myhy import Lisp

dsl = Lisp()  # an instance of Lisp() contains your entire 'language'


@dsl.function  # decorated Python functions become part of the DSL
def hello():
    return "Hello, MyHy!"

Use the myhy executable to use the language.

Provide the path to your DSL (my_lisp:dsl) and some code:

myhy my_lisp:dsl -c "(hello)"

Functions registered in myhy can take arguments.

@dsl.function
def hello(addressee):
    return f"Hello, {addressee}!"

myhy my_lisp:dsl -c "(hello you)"

Write Lisp code to a file.

echo "(hello everyone)" > lisp.txt

Run it with the -f flag.

myhy my_lisp:dsl -f lisp.txt`
