Command Help

[jobala]

Command help is shown when a user adds the --help flag after a command. For Commando, I want to separate concerns between registering commands and command groups and their help information. Developers will define help in help.yaml file then commando will load the file and add help to the commands.

The yaml file should have the following format

parent child grand-child
    type: command
    short-summary: "grand-child help"
    parameters:
      - name: --body
        short-summary: "itemBody"
        long-summary: |
            Usage: --body content=XX content-type=XX
            content: The content of the item.
      - name: --end
        short-summary: "dateTimeTimeZone"
        long-summary: |
            Usage: --end date-time=XX time-zone=XX

Running parent child grand-child --help will result in the output below

usage: parent child grand-child [-h|--help] --body <string> --end <string>

Arguments:

  -h  --help      Print help information
       --body      itemBody
       --end        dateTimeTimeZone
