Summary:
This is designed to make it easier to see how your codegen changes affected actual generated code.
Limitations:
A) This is NOT robust; if new directories are added that include generated files, they need to be added to tools/generated_dirs.txt. Note that subdirectories of the list are not included.
B) This is particular to my workflow which I don't claim is generally applicable. Ideally we would have a script that pumped out a diff that could be attached to PRs.
C) Only works on OSS and definitely won't work on windows.
How to use:
1) python setup.py ...
2) tools/git_add_generated_dirs
3) Edit codegen
4) python setup.py ...
4) git diff to see changes
5) If satisfied: tools/git_reset_generated_dirs, commit, etc.
If not satisfied: Go to 3)
