Feature #3388

Updated by nahi (Hiroshi Nakamura) almost 8 years ago

=begin

ruby-1.9.2-head > "aBcdeFghIj".start_with?(/abc/i)
=> false

In my implementation of start_with? it is easy enough to utilize #index, which works fine:

def start_with?(pattern)
index(pattern) == 0
end

But #end_with? is more difficult, and I had to use regular expressions.

def end_with?(suffix)
suffix = Regexp.escape(suffix) if String===suffix
/#{suffix}$/.match(self) ? true : false
end

However, we might get rid of the '? true : false' and return the MatchData, since that could be useful information.
