Regexp.escape

Regexp.escape(string) → new_string

static VALUE
rb_reg_s_quote(VALUE c, VALUE str)
{
    return rb_reg_quote(reg_operand(str, TRUE));
}

Returns a new string that escapes any characters that have special meaning in a regular expression:

Example

s = Regexp.escape('\*?{}.')      # => "\\\\\\*\\?\\{\\}\\."

For any string s, this call returns a MatchData object:

Example

r = Regexp.new(Regexp.escape(s)) # => /\\\\\\\*\\\?\\\{\\\}\\\./
r.match(s)                       # => #<MatchData "\\\\\\*\\?\\{\\}\\.">
