This cop checks for redundant returning of true/false in conditionals.
Example:
# bad
x == y ? true : false
# bad
if x == y
true
else
false
end
# good
x == y
# bad
x == y ? false : true
# good
x != y
Use Integer(ENV['SHIPPO_DEBUG'] || 0).positive?
instead of Integer(ENV['SHIPPO_DEBUG'] || 0) > 0

This cop checks for usage of comparison operators (==
,
>
, <
) to test numbers as zero, positive, or negative.
These can be replaced by their respective predicate methods.
The cop can also be configured to do the reverse.
The cop disregards #nonzero?
as it its value is truthy or falsey,
but not true
and false
, and thus not always interchangeable with
!= 0
.
The cop ignores comparisons to global variables, since they are often
populated with objects which can be compared with integers, but are
not themselves Interger
polymorphic.
Example: EnforcedStyle: predicate (default)
# bad
foo == 0
0 > foo
bar.baz > 0
# good
foo.zero?
foo.negative?
bar.baz.positive?
Example: EnforcedStyle: comparison
# bad
foo.zero?
foo.negative?
bar.baz.positive?
# good
foo == 0
0 > foo
bar.baz > 0
