screenwriter

Python Library for writing progress texts, echo messages, warnings and errors to standard output

Examples:

1 - Default prefix

from screenwriter import Screenwriter

sw = Screenwriter ()
sw.echo ('my output')

Output:
2019-07-26-11:16:04 my output

2 - Date Time parts in prefix

from screenwriter import Screenwriter

sw = Screenwriter ('%Y-%m-%d %H:%M:%S.%f ')
sw.echo ('my output')

Output:
2019-07-26 11:16:04 my output

3 - Error, Warning & Info standard prefixes

from screenwriter import Screenwriter

sw = Screenwriter ()
sw.error ('an error message')
sw.warn  ('a warming message')
sw.info  ('an informational message')

Output:
2019-07-29-11:39:00 ERROR: an error message
2019-07-29-11:39:00 WARN:  a warming message
2019-07-29-11:39:00 INFO:  an informational message

4 - Trimming content length

By default, log strings are trimmed to 120 chars. You can change this setting:

from screenwriter import Screenwriter

sw = Screenwriter ()
sw.set_maxlen (80) #Set maximum length to 80

5 - Dynamically toggele output

You can toggle the output between ON and OFF.

from screenwriter import Screenwriter

sw = Screenwriter ()
sw.echo ('print this line')
sw.set_verbose (False)
sw.echo ('do not print this line')
sw.set_verbose (True)
sw.echo ('print this line')

Output:
2019-10-05-20:09:10 print this line
2019-10-05-20:09:10 print this line
