Description:

autocall 1.1.1

Call function directly in cmd line
Features

Allow user call functions directly in command line.
Generate help tips automatically.
Add default called functions if not function was specific.

Notice

It's better to add argument type for each autocall functions.
str type argument must be defined explicitly.
@cmdline_default is a subset of @cmdline, which means function with @cmdline_default will have @cmdline implicitly.
Arguments of function with @cmdline_default should be optional or no argument.

TODO

Support class's function with self as the first argument.

Code example
#!/bin/python3.8
from autocall import *

# The tar @cmdline is used to register the function.
@cmdline
def test1():
print(f'test1()')
pass

@cmdline
@cmdline_default
def test2(arg: int = 0):
print(f'test2({arg})')
pass

@cmdline
def test3(arg1, arg2: str = 'this is a string'):
print(f'test3({arg1}, {arg2})')

@cmdline
def test4(arg1, arg2: int):
'You can add some extra information here.'
print(f'test4({arg1}, {arg2})')
pass

@cmdline_default
def test5(arg1: int = 1, arg2: str = 'good'):
print(f'test5({arg1}, {arg2})')

# main function

option:
--test1

--test2 [arg = 0]
The function will be called directly if not specific.

--test3 arg1 [arg2 = this is a string]

--test4 arg1 arg2
You can add some extra information here.

--test5 [arg1 = 1] [arg2 = good]
The function will be called directly if not specific.

--help [verbose = notverbose]
Give the argument "verbose" instead of "notverbose" to print detail information.

~/autocall/src $ ./test.py --test5 10 'hello'
test5(10, hello)
~/autocall/src $ ./test.py
test2(0)
test5(1, good)
