git - 'git diff' 可以只输出长行中的更改吗？

Question

当我对仅包含一个很长行的文件进行更改时，可以 git diff只输出改变的那部分行？
我知道git diff --word-diff将仅以颜色突出显示已更改的部分，但仍会输出整行。
是否可以选择只输出已更改的那部分行？或者也许是一个只能匹配 git diff --word-diff 的彩色部分的 grep 模式?

是的，使用 git diff --word-diff=porcelain .

Use a special line-based format intended for script consumption.Added/removed/unchanged runs are printed in the usual unified diff format,starting with a +/- character at the beginning of the line andextending to the end of the line. Newlines in the input are represented bya tilde ~ on a line of its own.

对长线的小改动看起来像......
