原帖原話

“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.”

“我不希望改個空格就把整行替換掉,也不希望把一行註釋掉就當成整行改動——這樣我才能追蹤真正沒變的代碼邏輯。”

需求背景與痛點

痛在哪

格式化和註釋開關汙染 diff 歷史:真正的邏輯改動被淹沒,blame 和 review 全部失真。

可以做成什麼

能做成什麼

語義化 diff 層:比對前剝離空白與註釋、歸一化後高亮真實變更,做成 GitHub App + CLI 訂閱。

怎麼驗證它

  1. 讀完原帖的評論區,把重複出現的具體場景記下來——重複次數就是需求的密度。
  2. 搜索「Git / Code Review」相關的現有工具,確認它們只覆蓋了哪一環。
  3. 用一句話落地頁,投回 Stack Exchange 或同類社群,看有沒有人主動問價格。

已有方案與差異

git diff --ignore-whitespace(局部、不進歷史);語義 diff 學術工具(不成熟)

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
