Rtrim and ltrim function for ruby: is this ok?

Ruby
1

I created this function:

class String
def rtrim(character)

if self[-1, 1] == character.to_s
  self[0, self.length - 1]
end
return self

end

def ltrim(character)
if self[0, 1] == character.to_s
self[1, self.length]
end
return self
end
end

Is this ok? Am I not duplicating any built-in ruby functions? Does
anyone see any possible problems with these functions?

Thanks in advance!

I’m not sure this does what you want it to. The object referenced by
self has not changed because the [] method does not alter the String.

Perhaps. See String#rstrip and #lstrip.

Well there is, it is just sooo expensive :wink:

Thanks! To bad for the missing left-chomp
