🛠 Installing

Pre-requisites

• Ruby installed on local machine. Please go to this link if you need to install it.

Style Guide

1. Department Naming

Naming cops check for naming issue of your code, such as method name, constant name, file name, etc.

- Naming/VariableName

This cop makes sure that all variables use the configured style, snake_case for their names.

# bad
myVar = 5

# good
my_var = 5

- Naming/MethodName

This cop makes sure that all methods use the configured style, snake_case for their names.

# bad
def MyMethodName
  # code
end

# good
def my_method_name
  # code
end

- Naming/ClassAndModuleCamelCase

This cop checks for class and module names with an underscore in them.

# bad
class My_Class
end
module My_Module
end

# good
class MyClass
end
module MyModule
end

2. Department Metrics

Metrics cops deal with properties of the source code that can be measured, such as class length, method length, etc. Generally speaking, they have a configuration parameter called Max and when running rubocop --auto-gen-config, this parameter will be set to the highest value found for the inspected code. In this linter, Max value has being set to 10.

- Metrics/BlockLength

This cop checks if the length of a block exceeds some maximum value. Comment lines can optionally be ignored.

3. Department Layout

Layout cops inspect your code for consistent use of indentation, alignment, and white space.

- Layout/EmptyLines

This cop checks for two or more consecutive blank lines.

# bad - It has two empty lines.
my_method


my_method

# good
my_method

my_method
