optfunc2 0.1

Generate options from function.

Call function directly in cmd line

Features

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

Notice

1. It's better to add argument type for each autocall functions.
2. Function with @optfunc_default has @optfunc implicitly.
3. Arguments of function with @optfunc_default should be optional or no argument.
4. Not support two type of variadic arguments.

TODO

1. Beautiful print.
