App Generator: How can I declare a variable for use in the entire generator?

refeniz

I have a rails app generator and I need to sanitize app_name in a few locations throughout my templates. It feels wrong to do it in every single spot that the sanitized_app_name is needed but I am having a hard time finding documentation on this sort of thing.

Aleksei Matiushkin

Define a constant:

APP_NAME = ->(input) { ...sanitizing code ... }.(:real_app_name)

and use it everywhere.
