Ask Git why a line exists. A read-only CLI that shows the commit message, line history, and issue references behind any tracked line.
gitwhen — pinpoint when a string, line, or file changed in git history. Zero deps wrapper around git log -S / git blame / git log --diff-filter.
Add a description, image, and links to the line-history topic page so that developers can more easily learn about it.
To associate your repository with the line-history topic, visit your repo's landing page and select "manage topics."
