This allows you to see the methods that are never called but are declared.

requirement :

• Rails > 6.1
• Ruby

Add this line to your application's Gemfile:

gem 'method_duplicator'

And then execute:

$ bundle

Or install it yourself as:

$ gem install method_duplicator

There is only one task at the moment that lists all the methods that are in the app/ folder and the number of times they are called.

$ rails method_duplicator:methods

• writing automatic tests (install RSpec)
• Filter the methods to have only the one with 0 declarations
• Make sure that in the file where the method is declared it can be called without the dot but not in the others
• Allow to pass parameters (path for example)
• customize colors for a better visibility
• optimization of the algo and the performance
• Export to CSV in tmp/
• Find another way (ctags, intellisense etc) to get the declarations without doing a complete parsing of the app
