Overview

Checks that the closing brace in a method definition is either on the same line as the last method parameter, or a new line.

When using the symmetrical (default) style:

If a method definition’s opening brace is on the same line as the first parameter of the definition, then the closing brace should be on the same line as the last parameter of the definition.

If a method definition’s opening brace is on the line above the first parameter of the definition, then the closing brace should be on the line below the last parameter of the definition.

When using the new_line style:

The closing brace of a multi-line method definition must be on the line after the last parameter of the definition.

When using the same_line style:

The closing brace of a multi-line method definition must be on the same line as the last parameter of the definition.

Examples:

EnforcedStyle: symmetrical (default)

# bad
def foo(a,
  b
)
end

# bad
def foo(
  a,
  b)
end

# good
def foo(a,
  b)
end

# good
def foo(
  a,
  b
)
end

EnforcedStyle: new_line

# bad
def foo(
  a,
  b)
end

# bad
def foo(a,
  b)
end

# good
def foo(a,
  b
)
end

# good
def foo(
  a,
  b
)
end

EnforcedStyle: same_line

# bad
def foo(a,
  b
)
end

# bad
def foo(
  a,
  b
)
end

# good
def foo(
  a,
  b)
end

# good
def foo(a,
  b)
end

#check, #check_brace_layout, #check_new_line, #check_same_line, #check_symmetrical, #children,
#closing_brace_on_same_line?

This method depends on the fact that we have guarded against implicit and empty literals.

#empty_literal?, #ignored_literal?, #implicit_literal?,
#last_line_heredoc?

Starting with the parent node and recursively for the parent node’s children, check if the node is a HEREDOC and if the HEREDOC ends below or on the last line of the parent node.

#new_line_needed_before_closing_brace?

Returns true for the case.

#opening_brace_on_same_line?

This method depends on the fact that we have guarded against implicit and empty literals.

#add_global_offense

Adds an offense that has no particular location.

#add_offense

Adds an offense on the specified range (or node with an expression) Unless that offense is disabled for this range, a corrector will be yielded to provide the cop the opportunity to autocorrect the offense.

#begin_investigation

Called before any investigation.

#callbacks_needed,
#cop_config

Configuration Helpers.

#cop_name, #excluded_file?,
#external_dependency_checksum

This method should be overridden when a cop’s behavior depends on state that lives outside of these locations:

#inspect,
#message

Gets called if no message is specified when calling add_offense or add_global_offense Cops are discouraged to override this; instead pass your message directly.

#name

Alias for Base#cop_name.

#offenses,
#on_investigation_end

Called after all on_…​

#on_new_investigation

Called before all on_…​

#on_other_file

Called instead of all on_…​

#parse

There should be very limited reasons for a Cop to do it’s own parsing.

#parser_engine,
#ready

Called between investigations.

#relevant_file?,
#target_gem_version

Returns a gems locked versions (i.e.

#target_rails_version, #target_ruby_version, #annotate, #apply_correction, #attempt_correction,
#callback_argument

Reserved for Cop::Cop.

#complete_investigation

Called to complete an investigation.

#correct, #current_corrector,
#current_offense_locations

Reserved for Commissioner:

#current_offenses, #currently_disabled_lines, #custom_severity, #default_severity, #disable_uncorrectable, #enabled_line?, #file_name_matches_any?, #find_message, #find_severity, #range_for_original, #range_from_node_or_range,
#reset_investigation
