synr 0.4

A consistent AST for Python

Synr

Synr is a library that provides a stable Abstract Syntax Tree for Python.

Features

• The Synr AST does not change between Python versions.
• Every AST node contains line and column information.
• There is a single AST node for assignments (compared to three in Python's ast module).
• Support for returning multiple errors at once.
• Support for custom error reporting.

Usage

import synr

def test_program(x: int):
  return x + 2

# Parse a Python function into an AST
ast = synr.to_ast(test_program, synr.PrinterDiagnosticContext())
