如何仅用第一行输出git日志？ [英] How to output git log with the first line only?

问题描述

我试图自定义 git log 的格式。我想要所有提交显示在一行。每行只应该显示提交消息的第一行。

我发现了 git log --pretty = short 应该做的伎俩，但在我的电脑上显示完整的日志为 git log does（除了时间戳）。

另外，我尝试使用占位符在手册页中定义。虽然，我找不到缩短日志消息的命令。我试过这行： git log --pretty = format：'％h：％s'它显示了短的散列％h 和完整的消息％s 在一行中。

我正在使用 git版本1.7.3.1.msysgit.0 在Vista。

也许它有事可做用我写我的提交信息的方式。这里是一个例子：

 增加了一些功能。 
 +在Foo类中增加了打印功能。 
 +增加了从foo到baz的转换。 
  

所以，给出的例子我只想输出增加了一些功能

解决方案

$ b

  git log --pretty = oneline --abbrev-commit 
  

问题可能是您在第一行之后缺少空行。上面的命令通常适用于我，但我只是在没有空的第二行的提交上进行测试。我得到了和你一样的结果：整条消息在一行。

空的第二行是git commit消息的标准。你看到的行为可能是有意实现的。

提交消息的第一行是一个简短的描述。如果你不能把它放在一行中，你可以使用几个，但是在第一个空行之前，git会把所有内容都看作是简短描述。 oneline 打印整个简短的描述，所以你的3行。

I am trying to customize the format for git log. I want all commits to be shown in one line. Each line should only show the first line of the commit message.
I found out that git log --pretty=short should do the trick but on my computer it shows the full log as git log does (besides the time stamp).

Further, I tried to use the placeholders as defined in the man page. Though, I could not find a command to shorten the log message. I tried this line git log --pretty=format:'%h : %s' which shows the shorted hash %hand the full message %s in one line.

I am using git version 1.7.3.1.msysgit.0 on Vista.

Maybe it has something to do with the way I write my commit messages. Here is an example:

Added some functionality.
+ Added print function in Foo class.
+ Added conversion from foo to baz.

So, with the example given I only want to be output Added some functionality. prepended by the shortend hash.

解决方案

Have you tried this?

git log --pretty=oneline --abbrev-commit

The problem is probably that you are missing an empty line after the first line. The command above usually works for me, but I just tested on a commit without empty second line. I got the same result as you: the whole message on one line.

Empty second line is a standard in git commit messages. The behaviour you see was probably implemented on purpose.

The first line of a commit message is meant to be a short description. If you cannot make it in a single line you can use several, but git considers everything before the first empty line to be the "short description". oneline prints the whole short description, so all your 3 rows.
