forkedsubprocess 1.0.3

Forked subprocess support for Python

Forked subprocess support for Python

This package allows for the running of a subprocess in the background, including the sending of data to the subprocess and receiving of data from it. Threads are used to achieve the reading/writing of data.

Basic usage

from forkedsubprocess import ForkedSubprocess

process = ForkedSubprocess(['cat'])
process.run()
process.send('some string')
returncode = process.wait()

stdout = process.stdout
stderr = process.stderr
output = process.output

Writing output to console

Output can be written to the console at the same time using enable_output=True.

from forkedsubprocess import ForkedSubprocess

process = ForkedSubprocess(['cat'], enable_output=True)
process.run()
process.send('some string')
returncode = process.wait()

stdout = process.stdout
stderr = process.stderr
output = process.output

Using a callback

A callback can be used for each line of output received.

from forkedsubprocess import ForkedSubprocess

def my_callback(line: str):
	print(f'LINE: {line}')

process = ForkedSubprocess(['cat'], output_callback=my_callback)
process.run()
process.send('some string')
returncode = process.wait()

stdout = process.stdout
stderr = process.stderr
output = process.output
