Get all git commits since last tag
提问by ChocoDeveloper
When I'm going to tag a commit, I need to know what changed since the last tagged commit. Eg:
当我要标记提交时，我需要知道自上次标记提交以来发生了什么变化。例如：
a87a6sdf87a6d4 Some new feature
a87a6sdf87a6d3 Some bug fix
a87a6sdf87a6d2 Some comments added
a87a6sdf87a6d1 Some merge <- v1.4.0
In this example I would like to know about the 3 newest commits, or be able to print a log like above, that shows both commits their tags if any. And when I see there has been a new feature added, I would tag it v1.5.0.
在这个例子中，我想知道 3 个最新的提交，或者能够像上面那样打印日志，显示两个提交的标签（如果有的话）。当我看到添加了新功能时，我会将其标记为 v1.5.0。
How do you deal with this? Is this how I'm supposed to use tags? What should I write in the tag message? I always leave it blank: git tag -a v1.2.3 -m ''
你如何处理这个问题？这是我应该如何使用标签吗？我应该在标签消息中写什么？我总是把它留空：git tag -a v1.2.3 -m ''

git log <yourlasttag>..HEAD?
git log <yourlasttag>..HEAD?
If you want them like in your example, on the one line with commit id + message, then
如果您希望它们像在您的示例中一样，在带有 commit id + message 的一行上，然后
git log <yourlasttag>..HEAD --oneline
git log <yourlasttag>..HEAD --oneline
and in case you don't know your latest tag or want this to be dynamic, on windows you could do
如果你不知道你的最新标签或希望它是动态的，在 Windows 上你可以这样做
for /f "delims=" %a in ('git describe --tags --abbrev^=0') do @set latesttag=%a
git log %latesttag%..HEAD --oneline
and on linux / git bash / windows bash
并在 linux / git bash / windows bash
git log $(git describe --tags --abbrev=0)..HEAD --oneline
Also, if you have a case where you know a tag in history and want to print everything from that tag up to current situation, you might want to add also --decorateso it would print out any tags in between.
此外，如果您有一个案例，您知道历史中的一个标签，并且想要打印从该标签到当前情况的所有内容，您可能还想添加，--decorate以便打印出介于两者之间的任何标签。

If your current commit is also a tag and you want to dynamically get the changes since the previous tag, without knowing the latest tag nor previous tag name, you can do:
如果您当前的提交也是一个标签，并且您想动态获取自上一个标签以来的更改，而不知道最新的标签和前一个标签名称，您可以执行以下操作：
git log --oneline $(git describe --tags --abbrev=0 @^)..@
Note that @is short for HEAD.
请注意，它@是 的缩写HEAD。
