HELP_MAPPINGS, THOR_RESERVED_WORDS, VERSION

Instance Attribute Summary

Attributes included from Base

#options

Instance Method Summary collapse

Dynamic Method Handling

This class handles dynamic methods through the method_missing method

#method_missing(meth, *args) ⇒ Object

If a task is not found on Thor::Runner, method missing is invoked and Thor::Runner is then responsable for finding the task in all classes.
