Experimental module for AST transformations

Install

pip install git+https://github.com/nvbn/__transformers__

Usage

Available transformations:

• ellipsis_partial – map(lambda x: x + 1, ...) to lambda y: map(lambda x: x + 1, y);
• matmul_pipe – "hello world" @ print to print("hello world").

Enable transformations in code:

from __transformers__ import ellipsis_partial, matmul_pipe
  
range(10) @ map(lambda x: x ** 2, ...) @ list @ print 

Run code with transformations:

➜ python -m __transformers__ -m python_module   
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

➜ python -m __transformers__ python/module/path.py                 
[0, 1, 4, 9, 16, 25, 36, 49, 64, 81]

Manually enable transformations from code:

from __transformers__ import setup

setup()

import module_that_use_transformers
