Useful methods in the Mnd::Commands::Base

Base#selected_repos

Get currently selected repos based on command line arguments.

For example when running, mnd logs mynewsdesk apiary then the selected_repos will be ["mynewsdesk", "apiary"].

However if no apps are specified it returns an empty array so when running mnd logs the selected_repos will be []. You might want to either display an error (return display.error "No repo specified if selected_repos.empty?") or default to use all apps (selected_repos.presence || Repo.all) in that case.

Base#display

Use display to get a display to print message instead of puts everywhere. It supports color in terminal. By default:

• display.info: default color
• display.error: red
• display.warn: yellow
• display.debug: light_black

Base#run(cmd, repo = nil)

Use it to run external command.

Parameters:

• cmd, String of the command you want to run
• repo, Optional if you want to run cmd on an repo

When repo is passed, it will cd to the root of repo then run the command.
