I'm working on a proprietary legacy code base and some variables are camel-cased while others are snake-cased. I'd like to clean up and enforce only camel-cased variable names but I can't seem to find a sniff for that. Here are the contents of my custom ruleset.
The ruleset.xml standard contains 68 sniffs
