Hi. There might be a better way, but one way to do it would be to use a
default value for the argument as None and warn the user if the value is
still None inside your code.
Something like this:
@task
def myTask(itsargument=None):
""" blah """
if itsargument == None:
usage()
sys.exit(1)
...

Sorry if this is obvious but I'm very novice at Python and Fabric.
I've researched tghe documentation I could find but could find
anything for this particular case. I have a simple fabfile which
includes a task requiring an argument:
@task
def myTask(itsargument):
""" blah """
...
It runs fine if I do:
fab -H host fabfile.myTask:itsargument=value
It works as I want it to. But if I omit the argument, I get a
TypeError exception:
TypeError: myTask() takes exactly 1 argument (0 given)
Which I would like to catch and output usage(). So far, I have not
been able to do so.
