Guide

This command language works similarly to python's function argument behavior. Positional Arguments comes first before Keyword Arguments. The keyword arguments are defined by using '=' operator while positional arguments wont need any.

rgb                             ✔
rgb color                       ✔
rgb color r=100 g=100 b=100     ✔
r=100 rgb                       ✘

Positional Arguments and Keyword Arguments (both key and value) can be defined in 3 possible ways and will be evaluated all the same manner, however quotes ' and double quotes " allow you to add whitespaces on arguments

# positional arguments
rgb
'rgb'
"rgb"

# keyword arguments
r=100
'r'='100'
"r"="100"

# with space

"simple argument"
'nice argument' = 100
"very nice argument" = 200
great_argument = 'this is a great argument'
