Overview

This class is abstract.

It cannot be directly instantiated. Subclasses must implement the abstract methods below.

Subclass this to implement a brew command. This is preferred to declaring a named function in the Homebrew module, because:

  • Each Command lives in an isolated namespace.
  • Each Command implements a defined interface.
  • args is available as an instance method and thus does not need to be passed as an argument to helper methods.
  • Subclasses no longer need to reference CLI::Parser or parse args explicitly.

To subclass, implement a run method and provide a cmd_args block to document the command and its allowed args. To generate method signatures for command args, run brew typecheck --update.
