我有哪些信息:主分支上的文件名(myfile.txt).上次使用提交"3"修改了文件,导致版本2.
我想要检索的内容:标签名称"0.0.2",其中包括自上一个标签"0.0.1"以来的提交"3"和"4".
(A)如何在2个标签之间获取更改的文件(参见此处):
git diff --name-only 0.0.1 0.0.2
这会打印'myfile.txt'等.
(B)通常应该完全符合我的需要(见这里):
git describe --always `git log --pretty=format:%H -n 1 myfile.txt`
但是我没有得到标签名称'0.0.2'或与此标签相关的提交.相反,我得到了提交3的提交SHA-1,其中包含myfile.txt的最新更改.
(C)如果以下命令打印相应的标记名称,则注释标记:
git for-each-ref --format='%(refname) %(objecttype)' refs/tags
打印:
refs/tags/0.0.1 tag
refs/tags/0.0.2 tag
refs/tags/0.0.3 tag
refs/tags/0.0.4 tag
题
所以我的问题是:(B)对我来说是正确的方式吗?如果是,我如何更改它确实获得所需的标签名称?还是有另一种方式而不是(B)得到我需要的东西?
git describe --contains `git log --pretty=format:%H -n 1 myfile.txt` | sed 's/\(.*\)[~^].*/\1/'
git-describe文档中的相关标志描述:
--always
Show uniquely abbreviated commit object as fallback.
这不是你想要的.这允许打印提交哈希而不是标记.
--tags
Instead of using only the annotated tags, use any tag found in refs/tags
namespace. This option enables matching a lightweight (non-annotated) tag.
这更接近,因为它允许使用所有标签,注释与否.但是,它仍然受到在上次提交之前查找标记的默认行为的影响.
--contains
Instead of finding the tag that predates the commit, find the tag that comes
after the commit, and thus contains it. Automatically implies --tags.
答对了.
给定具有以下提交历史记录的存储库:
$ git log --decorate=short -p | grep -v Author

请注意,文件test.txt在提交#1-4中编辑,但不在#5中编辑.提交#5被标记为v0.0.3,这是我们想要的输出.
只运行git命令会产生以下输出:
$ git describe --contains `git log --pretty=format:%H -n 1 test.txt`
v0.0.3~1
在~1表明在文件的最后一个变化是1承诺提供的标签后面.sed为了完整起见,使用管道来自行获取标签.
$ git describe --contains `git log --pretty=format:%H -n 1 test.txt` | sed 's/\(.*\)[~^].*/\1/'
v0.0.3
