Ruby: generating new Regexps from strings

Asked 2011-03-24T00:01:47.593

Is there any way to convert String to Regexp (in Ruby)? Let's say:

'example' ---> /example/

My purpose is generating Regexps dynamically.

ruby regex string

You can also write...

regex = Regexp.compile(string)

...which is a very descriptive name. This method compiles the source code (string) into a nondeterministic finite automaton (regex). The NFA can then be reused over and over.
