If the else
branch of a conditional consists solely of an if
node,
it can be combined with the else
to become an elsif
.
This helps to keep the nesting level from getting too deep.
Example:
# bad
if condition_a
action_a
else
if condition_b
action_b
else
action_c
end
end
# good
if condition_a
action_a
elsif condition_b
action_b
else
action_c
end

This cop checks for multiple expressions placed on the same line. It also checks for lines terminated with a semicolon.

This cop checks for numeric comparisons that can be replaced by a predicate method, such as receiver.length == 0, receiver.length > 0, receiver.length != 0, receiver.length < 1 and receiver.size == 0 that can be replaced by receiver.empty? and !receiver.empty.
Example:
# bad
[1, 2, 3].length == 0
0 == "foobar".length
array.length < 1
{a: 1, b: 2}.length != 0
string.length > 0
hash.size > 0
# good
[1, 2, 3].empty?
"foobar".empty?
array.empty?
!{a: 1, b: 2}.empty?
!string.empty?
!hash.empty?
Use !empty?
instead of size > 0

. It can be configured to check only in conditions, or in
all contexts.
Example: EnforcedStyle: always (default)

This cop can check for array literals made up of word-like strings, that are not using the %w() syntax.
Alternatively, it can check for uses of the %w() syntax, in projects which do not want to include that syntax.
Configuration option: MinSize
If set, arrays with fewer elements than this value will not trigger the
cop. For example, a MinSize
of 3
will not enforce a style on an
array of 2 or fewer elements.
Example: EnforcedStyle: percent (default)
# good
%w[foo bar baz]
# bad
['foo', 'bar', 'baz']
Example: EnforcedStyle: brackets
# good
['foo', 'bar', 'baz']
# bad
%w[foo bar baz]

Checks that braces used for hash literals have or don't have surrounding space depending on configuration.
Example: EnforcedStyle: space
# The `space` style enforces that hash literals have
# surrounding space.
# bad
h = {a: 1, b: 2}
# good
h = { a: 1, b: 2 }
Example: EnforcedStyle: no_space
# The `no_space` style enforces that hash literals have
# no surrounding space.
# bad
h = { a: 1, b: 2 }
# good
h = {a: 1, b: 2}
Example: EnforcedStyle: compact
# The `compact` style normally requires a space inside
# hash braces, with the exception that successive left
# braces or right braces are collapsed together in nested hashes.
# bad
h = { a: { b: 2 } }
# good
h = { a: { b: 2 }}
