Thanks for replying so quickly.
We have tried CodeNarc, but I am not a big fan at all, it has nowhere near the capabilities of Sonar. To be honest we use Sonar in our company and I wouldn’t necessarily want to use another tool. Apart from the issue GoSu, Sonar is a great tool and we will be using it a lot in future too.
Size of the codebase? Honest answer is I have no idea, I am not that close to the code, I am more looking at the tooling side of things. What I do know is that InsuranceSuite offered by Guidewire is a huge suite of products, used by many of the biggest insurance companies in the world, to run their operations. https://www.guidewire.com/customers
Of course if we could use Sonar I could tell you exactly how many!
If you want any further information then I am more than happy to take this offline, in the meantime I will keep a look out for further developments.
