un_used_methods

UnUsedMethods Gem

The un_used_methods gem is designed to help you identify and clean up unused methods in your Ruby on Rails application. In a large codebase, it can be challenging to track which methods are actively used and which are obsolete. The un_used_methods gem scans your application's codebase and identifies methods that are defined but not used anywhere else in your project. This helps you spot and remove unnecessary code, improving maintainability and performance.

Features

• Scans for method definitions across various directories (models, controllers, helpers, views, and more).
• Checks for method usage in code files and view templates.
• Reports methods that are defined but not used in the project.

Installation

Add this line to your application's Gemfile:

gem 'un_used_methods'

Then run:

bundle install

Usage

To use the gem, run the following command:

bundle exec un_used_methods find_unused

This command will analyze your codebase and print out any unused methods it finds. The gem scans through Ruby files, HTML/ERB templates, and other relevant file types to ensure comprehensive coverage.

Example Output

Method 'test' called in file: app/models/test.rb
Method 'another_method' not called anywhere in the project

Unused Methods found in your model, controller and helper directories:
app/models/test.rb: another_method

Configuration

The gem uses default settings to scan common directories and file types. If you need to customize the directories or file types to scan, you can modify the gem's configuration within the codebase.
