This cop checks code that can be written more easily using
Object#presence
defined by Active Support.
Example:
# bad
a.present? ? a : nil
# bad
!a.present? ? nil : a
# bad
a.blank? ? nil : a
# bad
!a.blank? ? a : nil
# good
a.presence
Example:
# bad
a.present? ? a : b
# bad
!a.present? ? b : a
# bad
a.blank? ? b : a
# bad
!a.blank? ? a : b
# good
a.presence || b
Always use raise

This cop checks for uses of fail
and raise
.
Example: EnforcedStyle: only_raise (default)
# The `only_raise` style enforces the sole use of `raise`.
# bad
begin
fail
rescue Exception
# handle it
end
def watch_out
fail
rescue Exception
# handle it
end
Kernel.fail
# good
begin
raise
rescue Exception
# handle it
end
def watch_out
raise
rescue Exception
# handle it
end
Kernel.raise
Example: EnforcedStyle: only_fail
# The `only_fail` style enforces the sole use of `fail`.
# bad
begin
raise
rescue Exception
# handle it
end
def watch_out
raise
rescue Exception
# handle it
end
Kernel.raise
# good
begin
fail
rescue Exception
# handle it
end
def watch_out
fail
rescue Exception
# handle it
end
Kernel.fail
Example: EnforcedStyle: semantic
# The `semantic` style enforces the use of `fail` to signal an
# exception, then will use `raise` to trigger an offense after
# it has been rescued.
# bad
begin
raise
rescue Exception
# handle it
end
def watch_out
# Error thrown
rescue Exception
fail
