Looking for feedback on vqmod

i read some comments on their site suggesting my biggest concerns are a non issue.

I do like the concept of what it is trying to do but not sure about the impact on performance...

I'm not even sure that i will need to use it for an upcoming project but... does anyone have any comments to make about this product???

thanks

Opinion in the wider programming community is divided on vQmod.

Its goals are:

• Change how core code works in a separate file that isn't replaced in updates.

• Allow changes to be added and removed easily.

• Allow changes from different developers to work together as much as possible.

Alternatives include:

• Overrides - you copy a core file and make your changes, which is how OC themes work. The problem with this is that only one override can happen at a time so you couldn't have multiple extensions.

• Hooks - Prestashop uses this method, and the code includes "hooks" where you can change things. Unfortunately, if there isn't a hook where you need it, then you can't achieve what you're trying to do without modifying core code.

vQmod is great, a slight downside is that if you're doing a lot of changes then you do end up with a big complicated file that can be hard to understand, but it's not too bad if written well.

The other thing is that if 2 vQmods try and modify the same part of a core file then 1 of them will probably fail. I'm not really sure if you can blame vQmod for that though - if 2 developers want to modify the same thing, there's going to be an issue.

So overall, I think it's great, and it's the best method of achieving its goals that I've seen.
