Includes:
Alignment, ConfigurableEnforcedStyle, MultilineElementIndentation
Defined in:
lib/rubocop/cop/layout/first_parameter_indentation.rb

Overview

This cop checks the indentation of the first parameter in a method definition. Parameters after the first one are checked by Layout/ParameterAlignment, not by this cop.

For indenting the first argument of method calls, check out Layout/FirstArgumentIndentation, which supports options related to nesting that are irrelevant for method definitions.

Examples:


# bad
def some_method(
first_param,
second_param)
  123
end

EnforcedStyle: consistent (default)

# The first parameter should always be indented one step more than the
# preceding line.

# good
def some_method(
  first_param,
second_param)
  123
end

EnforcedStyle: align_parentheses

# The first parameter should always be indented one step more than the
# opening parenthesis.

# good
def some_method(
                 first_param,
second_param)
  123
end
