Overview

Checks that reference brackets have or don’t have surrounding space depending on configuration.

Examples:

EnforcedStyle: no_space (default)

# The `no_space` style enforces that reference brackets have
# no surrounding space.

# bad
hash[ :key ]
array[ index ]

# good
hash[:key]
array[index]

EnforcedStyle: space

# The `space` style enforces that reference brackets have
# surrounding space.

# bad
hash[:key]
array[index]

# good
hash[ :key ]
array[ index ]
