原帖原话

“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.”

“我不希望改个空格就把整行替换掉,也不希望把一行注释掉就当成整行改动——这样我才能追踪真正没变的代码逻辑。”

需求背景与痛点

痛在哪

格式化和注释开关污染 diff 历史:真正的逻辑改动被淹没,blame 和 review 全部失真。

可以做成什么

能做成什么

语义化 diff 层:比对前剥离空白与注释、归一化后高亮真实变更,做成 GitHub App + CLI 订阅。

怎么验证它

  1. 读完原帖的评论区,把重复出现的具体场景记下来——重复次数就是需求的密度。
  2. 搜索「Git / Code Review」相关的现有工具,确认它们只覆盖了哪一环。
  3. 用一句话落地页,投回 Stack Exchange 或同类社群,看有没有人主动问价格。

已有方案与差异

git diff --ignore-whitespace(局部、不进历史);语义 diff 学术工具(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
