Have you ever felt need to compare two arrays in ColdFusion or comparing two structs or may be two queries. If you are reading this, I am sure you felt at some point and if not, you can still read on :)
We use arrays, structs and queries so regularly in ColdFusion that at some point or the other we have to compare them and we dump it to check if its coming fine. Dump is such a powerful tag in ColdFusion that you should use it but what if you want to write a script to check that. Ahhh... cfdump cannot be used there right.
Well not to worry, I have written a code, in fact to be precise I have modified a script (courtesy-cflib.org) which will allow you to compare arrays or structs or queries. Even if you have complex objects like array of struct or array inside struct or query in array of struct or whatever possiblity you can think of these three, you can easily compare using three simple functions: arrayCompare(leftarray, rightarray), structCompare(leftStruct, rightStruct), queryCompare(leftQuery, rightQuery).
I will post complete code n the end, you can save that in .cfm file and call the functions at your will. So it's like if you have two comparable variabes:array of structs, you just need to pass both of them to arrayCompare() OR if you have complex structs having array or query inside you need to call arrayStruct. Handling of array, struct or query present inside your variable will be automatically taken care of.
If both the variables passed by you are equal then this will return a boolean true else false. Find comments inline to understand the code.
So go ahead, you this file, call functions and compare your complex variables at ease.

This code is also available at cflib.org but I have modified it according to the need, so it might not be the same. If you are looking for a complete set of three features(array, struct, query compare) this file is perfect for you.
Share if you feel its worth it. Comments will be a +1.
