Restrict the Hotspot Analysis to Parts of a Codebase

To restrict the analysis to the react-dom package, you tweak the arguments to Git and cloc. For Git, you do this by specifying a path. Move into your react repository and run the following:

prompt> git log --all --numstat --date=short  \
                --pretty=format:'--%h--%ad--%aN' --no-renames  \
                --after=2021-08-01 \
                -- packages/react-dom > react_dom_log.txt

The path separator, --, ensures that only the commits relating to react-dom get included.

For cloc, it’s even simpler: specify the directory of interest, packages/react-dom/ ...
