Whistle Blowers

Vinod Kumaar Ramakrishnan

Lightning Talk: 10 minutes


Most of the bad parts while coding goes in inadvertently during the rush hour of check-ins. I usually observe the rush hour to be close to the end of the day and the next day, the refactoring is put into back burner which grows into tech debts and makes you repay at a later stage. Along with the other devs in the team we set some simple rules in the CI to fail the build. The rules are

  • More than 12 lines in a method
  • NPath complexity more than 4 in a method
  • More than 4 lines of code copy pasted across any file

An intentional check in to avoid these rules and send in a bad code could not be prevented; but someone in a hurry or tired individual checking in gets a hint that code could be bad. A quick introspection will lead to corrective action and things could be addressed then and there instead of carrying a tech debt. The rules above are neither comprehensive nor does this guarantee awesome code, but it has caught me and others red handed when looking for quick gains. I will list some examples of refactored code to show how simple metrics helped to keep code readable.
