A copy of the ASDL parser used in CPython 3.5.

Project Description

A copy of the ASDL parser used in CPython 3.5, cleaned a bit and packaged here.

Installation

$ pip install asdl

Usage

from asdl import ASDLParser, parse

syntax = """
    module Lambda {
        term =
            Lambda(name x, term body) |
            Apply(term function, term argument) |
            Variable(name x)
    }
"""

print(ASDLParser().parse(syntax))

print(asdl.parse("./test/Python.asdl"))

Output:

Module(Lambda, [Type(term, Sum([Constructor(Lambda, [Field(name, x), Field(term, body)]), Constructor(Apply, [Field(term, function), Field(term, argument)]), Constructor(Variable, [Field(name, x)])]))])

Module(Python, [Type(mod, Sum([Constructor(Module, [Field(stmt, body, seq=True)]), Constructor(Interactive, [Field(stmt, body, seq=True)]), Constructor(Expression, [Field(expr, body)]), Constructor(Suite, [Field(stmt, body, seq=True)])])), Type(stmt, Sum([Constructor(FunctionDef, [Field(identifier, name), Field(arguments, args), Field(stmt, body, seq=True), Field(expr, decorator_list, seq=True), Field(expr, returns, opt=True)]), …
