bytesinsert 0.2.1

A library for inserting a piece of code into another piece of code

Description

A library allows to insert one piece of code into another piece of code secretly, without changing line numbers.

The current version supports only Python 3.6. Also it allows to insert only functions without arguments.

Usage

A library has a useful function insert_code, which inserts which takes the original code, the code to insert and line number for insertion. The simplest example of usage from the examples directory:

from bytesinsert import insert_code


def hello():
    print("1")
    print("3")


def new_code():
    print("2")


code_orig = hello.__code__
code_to_insert = new_code.__code__
success, result = insert_code(code_orig, code_to_insert, 6)
if success:
    exec(result)

The resulting output will be:

1
2
3

The insert_code function inserted code from the function new_code into the function hello by updating its bytecode.
