When developing on Windows I find StyleCop to be a really useful tool for keeping code consistent throughout projects and I sorely miss it when developing C# projects on OS X with MonoDevelop.
I knew about a StyleCop addin for MonoDevelop here but at the time of writing it's not compatible with the latest version of MonoDevelop (22.214.171.124).
Time to get my hands dirty then! I forked the project on GitHub and modified it so that it works with MonoDevelop 126.96.36.199, the repository is here.
Upgrading the project was relatively easy, just tweaking a few version numbers in the addin manifest and reset the references. I also adjusted the StyleCop violations to output as Warnings rather that Errors, this suited the way I like to see the violations.
Getting the addin to run is another matter though - StyleCop uses the registry. Mono has a registry implementation but I found there were security issues involved with non admin processed reading and writing to it so in order to install the addin a little tweak to the registry permissions was required:
Navigate to the registry file:
On my machine it was here:
Then adjust the security:
sudo chmod 777 last-btime
Here is a screen shot of it running:
