Find places affected by changes in a diff

Diffwhat

Diffwhat is a small tool to take changes from a diff and list all the places that are affected by those changes. It works only for ocaml. And it requires the project to be compiled beforehand.

ocaml-junit$ dune build
ocaml-junit$ git diff
diff --git a/junit/junit.ml b/junit/junit.ml
index 212339e..707adcf 100644
--- a/junit/junit.ml

     make ~name ~classname ~time Skipped

   let pass ~name ~classname ~time =
+
     make ~name ~classname ~time Pass
 end

ocaml-junit$ git diff -U0 | diffwhat.exe $PWD
