Project description

Package Documentation

Description

This project provides Python context managers to help redirect multiple forms of output into a buffer (capturing the output).

Installation

$ pip install redirect-streams

Basic Usage

The most common use of this project is to redirect stdout.

from io import BytesIO, SEEK_SET, TextIOWrapper
from os import system
from sys import stdout

from redirect_streams import redirect_stdout

with TextIOWrapper(BytesIO(), stdout.encoding) as buffer:
    with redirect_stdout(buffer):
        print('this will be saved in the buffer')
        # code below won't work with stdlib's redirect_stdout
        system('this will be saved in the buffer')
    buffer.seek(SEEK_SET)
    saved = buffer.read()
print(saved)

For other context managers and more detailed information, please refer to the documentation.
