Continuous shell process

Install

pip install shell_proc

Run

Run a series of terminal commands.

import sys
from shell_proc import Shell

with Shell(stdout=sys.stdout, stderr=sys.stderr) as sh:
    sh.run('mkdir storage')
    sh('cd storage')  # Same as sh.run()
    sh('python -m venv ./myvenv')
    sh('source ./myvenv/bin/activate')
    sh('pip install requests')
    sh('pip list')

Manually call commands and check results.

import io
import sys
from shell_proc import Shell

# Initialize and run tasks
sh = Shell('mkdir storage',
           'cd storage',
           'python -m venv ./myvenv',
           stderr=io.StringIO())

# Manually run tasks
if sh.is_windows():
    sh.run('call .\\myvenv\\Scripts\\activate.bat')
else:
    sh.run('source ./myvenv/bin/activate')

# Not exactly success. If True no output was printed to stderr. Stderr could also be warning like need to update pip
success = sh('pip install requests')
print("***** Successful install: ", success)
if not success:
    err = sh.get_stderr()  # All text collected into stderr from subprocess stderr
    print(err, file=sys.stderr)
    # sh.print_stderr()  # Also available

sh.stdout = io.StringIO()  # Start saving output for new tasks
sh('pip list')
print('***** Output Printed', sh.has_print_out())
sh.stdout.seek(0)  # Move to start of io.StringIO()
print(sh.stdout.read())  # Print all read data

# Should close when finished to stop threads from reading stdout and stderr subprocess.PIPE
# (will close automatically eventually)
sh.close()
