"""
|
37 |
To add a command create a new class and add a 'command' decorator. The class
|
38 |
must have a 'main' method which will contain the code to be executed.
|
39 |
Optionally a command can implement an 'update_parser' class method in order
|
40 |
to add command line arguments, or modify the OptionParser in any way.
|
41 |
|
42 |
The name of the class is important and it will determine the name and grouping
|
43 |
of the command. This behavior can be overriden with the 'group' and 'name'
|
44 |
decorator arguments:
|
45 |
|
46 |
@command(api='compute')
|
47 |
class server_list(object):
|
48 |
# This command will be named 'list' under group 'server'
|
49 |
...
|
50 |
|
51 |
@command(api='compute', name='ls')
|
52 |
class server_list(object):
|
53 |
# This command will be named 'ls' under group 'server'
|
54 |
...
|
55 |
|
56 |
The docstring of a command class will be used as the command description in
|
57 |
help messages, unless overriden with the 'description' decorator argument.
|
58 |
|
59 |
The syntax of a command will be generated dynamically based on the signature
|
60 |
of the 'main' method, unless overriden with the 'syntax' decorator argument:
|
61 |
|
62 |
def main(self, server_id, network=None):
|
63 |
# This syntax of this command will be: '<server id> [network]'
|
64 |
...
|
65 |
|
66 |
The order of commands is important, it will be preserved in the help output.
