OutputCatcher 0.0.4

Catches/silences stdout/stderr output.

A context manager that catches/suppresses output from sys.stderr and sys.stdout.

Usage

from outputcatcher import StdErrCatcher, StdOutCatcher

# Catching stdout
with StdOutCatcher() as fakeout:
    print('This is a test. you shouldn\'t see it right away.')
print('Captured stdout: {}'.format(fakeout.output))

# Catching stderr

    print('Testing stderr output.', file=sys.stderr)
print('Captured stderr: {}'.format(fakeerr.output))

API

StdOutCatcher(escaped=False, max_length=0)

Arguments

• escaped: If truthy, output is “encoded” using repr(), but without quotes. Default: False

• max_length: If non-zero, final output will not exceed max_length. Once max_length is reached, further write() calls will not write to the original stream. Default: 0
