Creating a regex expression moving strings around

Question

I need to find and replace a ton of code that was written and my text editor works with regex expressions but I dont know how to make them. How would I create a regex expression to do this:

from:

if ($q->param('wordOne[]') =~ m/wordTwo/)

to :

if (grep /wordTwo/, $q->param('wordOne[]')) { ... }

wordOne/Two can be any word that is where my problem is and im not sure how to format my regex for a find and then replace to my format

What editor? Their regex engines will be different. The general syntax is often `s/find(this)/replace with \1/g` or similar, but can be something like `find$this$` for example (Emacs) — BRPocock, Feb 05 '14 at 19:17

Search for:

if \(\$q->param\('([^']+)'\) =~ m/([^/]+)/\)

([^']+) captures the text in between param(' and ') =~. ([^/]+) is similar. See here for more information on capturing groups.

Replace with:

if (grep /\2/, $q->param('\1')) { ... }

\1 and \2 are backreferences to the captured text.

Output:

if (grep /wordTwo/, $q->param('wordOne[]')) { ... }

Find: (\$q->param$'.*?\[\]'$) =~ m(/.*?/)

Replace: grep \2, \1
