--- !ruby/object:RI::MethodDescription aliases: [] block_params: comment: - !ruby/struct:SM::Flow::P body: Element Reference---If passed a single <tt>Fixnum</tt>, returns the code of the character at that position. If passed two <tt>Fixnum</tt> objects, returns a substring starting at the offset given by the first, and a length given by the second. If given a range, a substring containing characters at offsets given by the range is returned. In all three cases, if an offset is negative, it is counted from the end of <em>str</em>. Returns <tt>nil</tt> if the initial offset falls outside the string, the length is negative, or the beginning of the range is greater than the end. - !ruby/struct:SM::Flow::P body: If a <tt>Regexp</tt> is supplied, the matching portion of <em>str</em> is returned. If a numeric parameter follows the regular expression, that component of the <tt>MatchData</tt> is returned instead. If a <tt>String</tt> is given, that string is returned if it occurs in <em>str</em>. In both cases, <tt>nil</tt> is returned if there is no match. - !ruby/struct:SM::Flow::VERB body: " a = "hello there"\n a[1] #=> 101\n a[1,3] #=> "ell"\n a[1..3] #=> "ell"\n a[-3,2] #=> "er"\n a[-4..-2] #=> "her"\n a[12..-1] #=> nil\n a[-2..-4] #=> ""\n a[/[aeiou](.)\\1/] #=> "ell"\n a[/[aeiou](.)\\1/, 0] #=> "ell"\n a[/[aeiou](.)\\1/, 1] #=> "l"\n a[/[aeiou](.)\\1/, 2] #=> nil\n a["lo"] #=> "lo"\n a["bye"] #=> nil\n" full_name: String#slice is_singleton: false name: slice params: | str[fixnum] => fixnum or nil str[fixnum, fixnum] => new_str or nil str[range] => new_str or nil str[regexp] => new_str or nil str[regexp, fixnum] => new_str or nil str[other_str] => new_str or nil str.slice(fixnum) => fixnum or nil str.slice(fixnum, fixnum) => new_str or nil str.slice(range) => new_str or nil str.slice(regexp) => new_str or nil str.slice(regexp, fixnum) => new_str or nil str.slice(other_str) => new_str or nil visibility: public
