pyteetime 1.0.0

Unix tee command for python

The Unix command tee splits the output of a program so that it is both displayed on screen and written to a file. The pyteetime package provides such a functionality in Python. It is based on the original code from A. Peck, with a few classmethods added.

Usage:

Run the example script tee-test.py listed here:

from pyteetime import tee
import sys

print('This prologue will appear on screen but not in a logfile')

LOGFILE = tee.stdout_start(append=False) # STDOUT
# from now on, all output is also copied to the logfile

tee.stderr_start(append=False) # STDERR
# from now on, all output to STDERR is also copied to stderr.log

print('This text will appear on screen and also in the logfile')

print('This will appear on screen and also in stderr.log', file=sys.stderr) 

# input from keyboard does not go to logfile:
answer = input('Enter something!\n')

# show the input to make sure it also goes into the logfile:
print('The user typed: %s' % (answer))

# data written to a file is not copied to the logfile:
DATAFILE = open('tee-test.dat','w+')
print(list(range(5)), file=DATAFILE)
DATAFILE.close()

print('This goes to the logfile but will not appear on screen', file=LOGFILE)

tee.stdout_stop()
# from now on, output to STDOUT will not go to stdout.log anymore

tee.stderr_stop()
# from now on, output to STDERR will not go to stderr.log anymore

print('This epilogue will appear on screen but not in a logfile')
