# A rule that enforces method names to be in underscored case.
|
|
|
|
#
|
|
|
|
# For example, these are considered valid:
|
|
|
|
#
|
|
|
|
# ```
|
|
|
|
# class Person
|
|
|
|
# def first_name
|
|
|
|
# end
|
|
|
|

# def date_of_birth

|

|
# def homepage_url
|
|
|
|
# end
|
|
|
|
# end
|
|
|
|
# ```
|
|
|
|
#
|
|
|
|
# And these are invalid method names:
|
|
|
|
#
|
|
|
|
# ```
|
|
|
|
# class Person
|
|
|
|
