Interpolating a string into a regex

Question

I need to substitute the value of a string into my regular expression in Ruby. Is there an easy way to do this? For example: ``` foo = "0.0.0.0" goo = "here is some other stuff 0.0.0.0" if goo =~ /value of foo here dynamically/ puts "success!" end ```

Accepted Answer

Same as string insertion.

```
if goo =~ /#{Regexp.quote(foo)}/
#...
```
