Writing custom linter in Go
Writing linters is simple. I was surprised how it’s easy to write a Go linter. Today, we’ll write a linter that will calculate the cyclomatic complexity of the Go code.
What is cyclomatic complexity?
Cyclomatic complexity is a software metric used to indicate the complexity of a program. ref
The idea is simple - every time we find any control flow statements we increase the complexity by one. I know I oversimplified it a bit but I don’t want to overwhelm you with unnecessary details.
