class RubbyCop::Cop::Layout::SpaceInsideStringInterpolation
This cop checks for whitespace within string interpolations.
@example
# Good if EnforcedStyle is no_space, bad if space. var = "This is the #{no_space} example" # Good if EnforceStyle is space, bad if no_space. var = "This is the #{ space } example"
Constants
- NO_SPACE_MSG
