Includes:
ConfigurableEnforcedStyle, RangeHelp
Defined in:
lib/rubocop/cop/layout/space_around_block_parameters.rb

Overview

Checks the spacing inside and after block parameters pipes. Line breaks inside parameter pipes are checked by ‘Layout/MultilineBlockLayout` and not by this cop.

Examples:

EnforcedStyleInsidePipes: no_space (default)

# bad
{}.each { | x,  y |puts x }
->( x,  y ) { puts x }

# good
{}.each { |x, y| puts x }
->(x, y) { puts x }

EnforcedStyleInsidePipes: space

# bad
{}.each { |x,  y| puts x }
->(x,  y) { puts x }

# good
{}.each { | x, y | puts x }
->( x, y ) { puts x }
