class RuboCop::Cop::Layout::SpaceInsideStringInterpolation
This cop checks for whitespace within string interpolations.
@example EnforcedStyle: no_space (default)
# bad var = "This is the #{ space } example" # good var = "This is the #{no_space} example"
@example EnforcedStyle: space
# bad var = "This is the #{no_space} example" # good var = "This is the #{ space } example"
Constants
