This cops checks the indentation of the here document bodies. The bodies are indented one step. In Ruby 2.3 or newer, squiggly heredocs (<<~) should be used. If you use the older rubies, you should introduce some library to your project (e.g. ActiveSupport, Powerpack or Unindent). Note: When Metrics/LineLength's AllowHeredoc is false(not default), this cop does not add any offenses for long here documents to avoid Metrics/LineLength's offenses.

Example:

# bad
<<-RUBY
something
RUBY

# good
# When EnforcedStyle is squiggly, bad code is auto-corrected to the
# following code.
<<~RUBY
  something
RUBY

# good
# When EnforcedStyle is active_support, bad code is auto-corrected to
# the following code.
<<-RUBY.strip_heredoc
  something
RUBY

required_ruby_version (1.9, declared in lean-attributes.gemspec) and TargetRubyVersion (2.1, declared in .rubocop.yml) should be equal.

Severity: Minor
Found in lean-attributes.gemspec by rubocop

Checks that required_ruby_version of gemspec and TargetRubyVersion of .rubocop.yml are equal. Thereby, RuboCop to perform static analysis working on the version required by gemspec.

Example:

# When `TargetRubyVersion` of .rubocop.yml is `2.3`.

# 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']
end

website  += "/bbatsov/rubocop" unless cond
puts        "rubocop"          if     debug

# bad for any configuration
set_app("RuboCop")
website  = "https://github.com/bbatsov/rubocop"
