Measuring time spent on specific file types in vim

Question

Is there a way to determine how much time I spend in certain types of files while working in vim? I would like to measure how much time I spend writing application code, not tests (they all have a predefined file name * _spec.rb)

Answer 1

Try the BufTimer plugin . This is the duration time in each file, so it is not precisely grouped by some filter, but it should be good enough.
