Use =~
in places where the MatchData
returned by #match
will not be used. Open
if e.message.match(/not in InService/i)
- Read upRead up
- Exclude checks
This cop identifies the use of Regexp#match
or String#match
, which
returns #<MatchData>
/nil
. The return value of =~
is an integral
index/nil
and is more performant.
Example:
# bad
do_something if str.match(/regex/)
while regex.match('str')
do_something
end
# good
method(str =~ /regex/)
return value unless regex =~ 'str'

Unused method argument - args
. If it's necessary, use _
or _args
as an argument name to indicate that it won't be used. You can also write as cleanup(*)
if you want the method to accept any arguments but don't care about them. Open
def self.cleanup(*args)

This cop checks for unused method arguments.
Example:
# bad

This cop checks for excessive nesting of conditional and looping constructs.
You can configure if blocks are considered using the CountBlocks
option. When set to false
(the default) blocks are not counted
towards the nesting level. Set to true
to count blocks as well.
The maximum level of nesting allowed is configurable.
Unused method argument - credentials
. If it's necessary, use _
or _credentials
as an argument name to indicate that it won't be used. You can also write as adminBucketUrl(*)

Useless assignment to variable - cluster
. Open
cluster = nil
- Read upRead up
- Exclude checks
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)

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
end
# good
