Class: Pod::Command::Debug

Inherits:
Pod::Command show all
Defined in:
lib/cocoapods-xp-binary-debug/command/debug.rb

Overview

TODO:

Create a PR to add your plugin to CocoaPods/cocoapods.org in the ‘plugins.json` file, once your plugin is released.

This is an example of a cocoapods plugin adding a top-level subcommand to the ‘pod’ command.

You can also create subcommands of existing or new commands. Say you wanted to add a subcommand to ‘list` to show newly deprecated pods, (e.g. `pod list deprecated`), there are a few things that would need to change.

  • move this file to ‘lib/pod/command/list/deprecated.rb` and update the class to exist in the the Pod::Command::List namespace

  • change this class to extend from ‘List` instead of `Command`. This tells the plugin system that it is a subcommand of `list`.

  • edit ‘lib/cocoapods_plugins.rb` to require this file
