akparse package
A simple and easy-to-use CLI parse tool package. You can use '-', '--', ',', '|', '{', '}', '[', ']', '=' and character to define your CLI API and the constraints are as follows:
- '-' : indicate a short option, followed by a character usually.
- '--': indicate a long option, followed by a word usually.
- ',' : indicate a required option of one CLI API defined.
- '|' : indicate a parallel option of one CLI API defined with same prefix.
- '{}': indicate the parallel option, always with '|' together.
- '[]': indicate the optional option.
- '=' : indicate the k-v option.
eg, one disk-file API:
# create a disk file when be defined: --create,-p=[--user=,-a=]
disk-file --create -p file_path
disk-file --create -p file_path --user u1 -a 777
# query a disk file when be defined: --query[{-p=|--list}]
disk-file --query
disk-file --query -p file_path
disk-file --query --list
