README ¶

Original: Nested Command(s) with Arguments

This is the original prototype work done to demonstrate how to combine the flag (or pflag) packages as part of an internal CLI processing engine. This work is superseded by the work(s) in its parent directory.

(original README.md) below:

This example attempts to use the flag (or pflag) package in combination with arguments that represent commands and sub-commands to process flags at each level of the sub-command.

Structure of initial command line:

rootCmd -rootArg1 -rootArg2 subCmd -subArg1 ... subSubCmd -subSubArg1
