This cop checks whether the end keywords are aligned properly.

Three modes are supported through the EnforcedStyleAlignWith configuration parameter:

If it's set to keyword (which is the default), the end shall be aligned with the start of the keyword (if, class, etc.).

If it's set to variable the end shall be aligned with the left-hand-side of the variable assignment, if there is one.

If it's set to start_of_line, the end shall be aligned with the start of the line where the matching keyword appears.

Example: EnforcedStyleAlignWith: keyword (default)

# bad

variable = if true
    end

# good

variable = if true
           end

Example: EnforcedStyleAlignWith: variable

# bad

variable = if true

Useless assignment to variable - e.
Open

  rescue ActiveRecord::RecordInvalid => e

This cop checks for every useless assignment to local variable in every scope. The basic idea for this cop was from the warning of ruby -cw:

assigned but unused variable - foo

Currently this cop has advanced logic that detects unreferenced reassignments and properly handles varied cases such as branch, loop, rescue, ensure, etc.

Example:

# bad

def some_method
  some_var = 1
  do_something
end

Example:

# good

def some_method
  some_var = 1
  do_something(some_var)
end

Unused block argument - request. You can omit the argument if you don't care about it.
Open

do_something do |bar|

define_method(:foo) do |bar|

Use tr instead of gsub.
Open

    name = CGI.unescape(wiki.split('wiki/').last.gsub("_", " "))
Severity: Minor
Found in app/models/entity.rb by rubocop

This cop identifies places where gsub can be replaced by tr or delete.

Example:

# bad
'abc'.gsub('b', 'd')
'abc'.gsub('a', '')
'abc'.gsub(/a/, 'd')
'abc'.gsub!('a', 'd')

# good
'abc'.gsub(/.*/, 'a')
'abc'.gsub(/a+/, 'd')
'abc'.tr('b', 'd')
'a b c'.delete(' ')

Non-local exit from iterator, without return value. next, break, Array#find, Array#any?, etc. is preferred.
Open

      return unless i.graph_node.present?
Severity: Minor
Found in lib/graph_bulk.rb by rubocop

This cop checks for non-local exits from iterators without a return value. It registers an offense under these conditions:

  • No value is returned,
  • the block is preceded by a method chain,
  • the block has arguments,
  • the method which receives the block is not define_method or define_singleton_method,
  • the return is not contained in an inner scope, e.g. a lambda or a method definition.

Example:

class ItemApi
  rescue_from ValidationError do |e| # non-iteration block with arg
    return { message: 'validation error' } unless e.errors # allowed
    error_array = e.errors.map do |error| # block with method chain
      return if error.suppress? # warned
      return "#{error.param}: invalid" unless error.message # allowed
      "#{error.param}: #{error.message}"
    end
    { message: 'validation error', errors: error_array }
  end

  def update_items
    transaction do # block without arguments
      return unless update_necessary? # allowed
      find_each do |item| # block without method chain
        return if item.stock == 0 # false-negative...
        item.update!(foobar: true)
      end
    end
  end
end

Unused method argument - request. If it's necessary, use _ or _request as an argument name to indicate that it won't be used.
Open

    def self.eligible?(founder, request)

This cop checks for unused method arguments.

Example:

# bad

def some_method(used, unused, _unused_but_allowed)

end

Example:

# good

def some_method(used, _unused, _unused_but_allowed)
  puts used
end

Literal false appeared as a condition.
Open

      fetch! if false # id_or_slug.present?
Severity: Minor
Found in lib/http/angel_list/base.rb by rubocop

This cop checks for literals used as the conditions or as operands in and/or expressions serving as the conditions of if/while/until.

Example:

# bad

if 20
  do_something
end

Example:

# bad

if some_var && true
  do_something
end

Example:

# good

Use delete instead of gsub.
Open

    string.gsub("\u0000", '').squish.to_s.encode('UTF-8',  invalid: :replace, undef: :replace, replace: '')
Severity: Minor

This cop identifies places where gsub can be replaced by tr or delete.

Example:

# bad
'abc'.gsub('b', 'd')
'abc'.gsub('a', '')

'abc'.gsub!('a', 'd')

# good
'abc'.gsub(/.*/, 'a')
