PyWriter

PyWriter is a utility class in Automata used for writing Python code along Abstract Syntax Tree (AST) nodes. PyWriter is initialized with an instance of PyReader which fetches the Python code. Once initialized, there are methods available to create, update, and delete from Python modules.

Usage Example

Below is an example illustrating the creation of a new Python module using PyWriter.

from automata.code_handling.py.writer import PyWriter
from automata.code_handling.py.reader import PyReader

# Initializing PyWriter
py_reader = PyReader()
py_writer = PyWriter(py_reader)

# Creating a new Python module
py_writer.create_new_module(
    module_dotpath="sample_module",
    source_code="print('Hello, world!')",
    do_write=True
)

In this example, create_new_module accepts a module path along with source code as strings, and a boolean indicating whether to write these changes to disk. The module’s path is given through dot notation (i.e., ‘sample_module’).

Limitations

While the PyWriter class provides a useful way to modify Python code programmatically, it has certain limitations. For instance, improper manipulation of Python code may lead to syntax errors or unexpected behaviour in the code. Additionally, the automatic writing of changes to disk may, in some cases, lead to data loss if not used carefully.
