Boilerplate detector

This script shows how much boilerplate a programming language has

Scripts have to be ececuted in a parent directory of a project or a workspace with many projects

Know your most used lines

bash lines.sh "<project dir>" "<file extension>
bash lines.sh ./../../project "*.go" > output-go-words.txt

Know your most used words

bash words.sh ./../../project "*.go" > output-go-words.txt

Example

Project https://github.com/algorand/go-algorand on commit b81994e0f2a0b4372e9c22673f6458c685e2f593 has this output:

> bash run.sh . '*.go' | tail -n 20

    893 )
   1080 require.NoError(t, err)
   2646 //
   4840 return
   5169 if err != nil {
  23718 
  26725 }
Total count:
213828

Which means that 5169 lines out of 213828 is this exact if line: if err != nil {. Which is ~2.4%. Golang projects mostly have a similar quantity of this line. Some have less but this line is very prevalent in golang.
