Convert a string to regular expression ruby

Question

I need to convert string like \"/[\\w\\s]+/\" to regular expression.

\"/[\\w\\s]+/\" => /[\\w\\s]+/

I tried using different Regexp

Answer 1

Using % notation:

%r{\w+}m => /\w+/m

or

regex_string = '\W+'
%r[#{regex_string}]

From help:

%r[ ] Interpolated Regexp (flags can appear after the closing delimiter)
