What was actually said

“I don't want a whitespace change to replace the whole line, and commenting a line shouldn't count as a rewrite either — so I can track the code that actually stayed the same.”

Background and pain

The pain

Reformatting and comment toggles pollute history: real logic changes drown, blame and review lose meaning.

A buildable angle

The opening

A semantic diff layer: strip whitespace/comments, normalize, then highlight real changes — shipped as a GitHub App plus CLI, subscription.

How to validate it

  1. Read the whole thread and note the recurring scenarios — repetition is the density of the need.
  2. Search existing tools around "git / code review" and check which single step they actually cover.
  3. Put up a one-line landing page, share it back to Stack Exchange, and see whether anyone asks about pricing.

a line into comments wouldn't replace the whole line either. This way I could be able to keep track of code that remains the same for a longer period of time. Dude, if you comment out a line, the functionality of your code changed. You need to understand that. I can see your point on whitespace, and you can 1) configure git to use Beyond Compare as its diff tool and 2) configure Beyond Compare to ignore whitespace changes. Quite how this fits in with "keep track of code that remains the same for a longer period of time" is questionable. Do you pull two branches form different time lines and di

Just for giggles, I fed ChatGPT your question and asked if there was any way to do it with git. Here's what it said ... What Git already supports Ignore whitespace changes in diffs Git can suppress whitespace-only changes during comparison: git diff -w git blame -w or: git diff --ignore-space-change This helps review history without noise. Ignore formatting commits in blame A common modern workflow: Run a formatter (black, prettier, clang-format) Put that commit hash into: .git-blame-ignore-revs Then: git config blame.ignoreRevsFile .git-blame-ignore-revs Now git blame skips formatting-only co
