Re: Regexp variable substitution of special variable

Write your replacement this way instead: s/$search/eval qq["$replace"]/e. The key is the /e and the eval using a bit of runtime constructed perl code.

Thanks to davido for noticing a bug that would prevent my original suggestion from working.

Another minor comment ... e's stack. `s/$search/qq["$replace"]/ee` is exactly the same as yours. Which is better is a matter of opinion. :-)	[reply] [d/l]

I think its better to make the second eval explicit and very visible because it is a very different sort of eval from the first /e. So I really, strongly, prefer my version. They're functionally equivalent but you can see that something really, highly unusual is happening in mine. It isn't so visible in yours.	[reply]
