           'bala'

some_str = 'ala' <<
           'bala'

# good
some_str = 'ala' \
           'bala'

Example: EnforcedStyle: double_quotes

# bad
'Just some text'
'No special chars or interpolation'

# good
"Just some text"
"No special chars or interpolation"
"Every string in #{project} uses double_quotes"

# bad
Gem::Specification.new do |spec|
  spec.required_ruby_version = '>= 2.2.0'
end

# bad
Gem::Specification.new do |spec|
  spec.required_ruby_version = '>= 2.4.0'
end

# good
Gem::Specification.new do |spec|
  spec.required_ruby_version = '>= 2.3.0'
end

# good
Gem::Specification.new do |spec|
  spec.required_ruby_version = '>= 2.3'
end

# good
Gem::Specification.new do |spec|
  spec.required_ruby_version = ['>= 2.3.0', '< 2.5.0']
