- Exclude checks
Checks for if and unless statements that would fit on one line if
written as modifier if/unless. The cop also checks for modifier
if/unless lines that exceed the maximum line length.
The maximum line length is configured in the Layout/LineLength
cop. The tab size is configured in the IndentationWidth of the
Layout/IndentationStyle cop.
Example:
# bad
if condition
do_stuff(bar)
end
unless qux.empty?
Foo.do_something
end
do_something_with_a_long_name(arg) if long_condition_that_prevents_code_fit_on_single_line
# good
do_stuff(bar) if condition
Foo.do_something unless qux.empty?
if long_condition_that_prevents_code_fit_on_single_line
do_something_with_a_long_name(arg)
end
if short_condition # a long comment that makes it too long if it were just a single line
do_something
end
