'''
err.py Encapsulated writing to sys.stderr
The idea of this module is that, for a GUI system (or a more advanced UI),
you can just import a different err module (or object) and keep
your code the same. (For instance, you often want a status window
which flashes warnings and info, and have error messages pop up an
alert to get immediate attention.
'''
import sys
def err(message, Code=0):
'''
report an error, with an optional error code
'''
if Code:
sys.stderr.write('Error #%i: %s\n'%(Code,message))
else:
sys.stderr.write('Error: %s\n'%message)
def warn(message, Code=0):
'''
report a warning, with an optional error code
'''
if Code:
sys.stderr.write('Warning #%i: %s\n'%(Code,message))
else:
sys.stderr.write('Warning: %s\n'%message)
def info(message, Code=0):
'''
report information/status, with an optional error code
'''
if Code:
sys.stderr.write('Info #%i: %s\n'%(Code,message))
else:
sys.stderr.write('Info: %s\n'%message)
