问题描述
从快照计算变更集时，Git并不总是正确选择大块边界. git diff 有一个-diff-algorithm 选项，可以对此进行一些调整； git diff --minimal 有时会比单独使用 git diff 产生更好的结果.
Git doesn't always choose hunk boundaries correctly, when calculating a changeset from snapshots. git diff has a --diff-algorithm option that allows some tweaking in this regard; git diff --minimal sometimes gives better results than git diff alone.
是否有一种方法也可以为 git add -p (它基本上以交互方式显示 diff 块)获得相同的优化变更集布局?似乎不允许使用-diff-algorithm 选项.
Is there a way to get the same optimised changeset layout also for git add -p (which basically shows the diff hunks interactively)? It doesn't seem to allow the --diff-algorithm option.
推荐答案
TL; DR版本
git -c diff.algorithm=minimal add -p
(需要Git 1.8.4或更高版本).
(requires Git version 1.8.4 or newer).
在最后研究之后，将其从评论中移至答案:
Moving this from comment to answer after the last bit of research:
从Git 1.8.4版开始，交互式add perl脚本(实现了 git add -p )遵循git配置中的 diff.algorithm 设置.这与 commit 2cc0f53 (2013年6月12日)结合在一起://github.com/johnkeeping"rel =" nofollow> John Keeping( johnkeeping ).
:
Since Git version 1.8.4, the interactive add perl script (which implements git add -p) obeys the diff.algorithm setting in your git configuration. This went in with commit 2cc0f53 (12 Jun 2013) by John Keeping (johnkeeping).
:
由于add--interactive是一个瓷器命令，因此应该遵守这一点配置变量.为此，请使其读取diff.algorithm和将其值传递给底层的diff-index和diff-files调用.
Since add--interactive is a porcelain command it should respect this configuration variable. To do this, make it read diff.algorithm and pass its value to the underlying diff-index and diff-files invocations.
此时，请勿在"git add"，"git reset"或"git"中添加选项结帐"(所有这些都可以调用git-add--interactive).如果用户想要覆盖他们可以使用的命令行上的值:
At this point, do not add options to "git add", "git reset" or "git checkout" (all of which can call git-add--interactive). If a user wants to override the value on the command line they can use:
git -c diff.algorithm=$ALGO ...
(已在提交e5c2909 中修复)(2013年6月23日)由 Junio C Hamano( gitster )；此修复程序也位于1.8.4中).
(with a fix in commit e5c2909 (23 Jun 2013) by Junio C Hamano (gitster); the fix is also in 1.8.4).
