How do I modify cygwin's PS1 for git bash completion?
提问by void.pointer
Here is my current PS1:
这是我目前的 PS1：
$ echo $PS1
\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n$
I have installed git bash completion and it isn't showing the current branch in my command prompt. I think this needs to be edited but I've got no idea what to change to make it show the current branch. Note that I like the colors and general structure (i.e. with $on its own line), so I'd like to keep that if possible.
我已经安装了 git bash completion，但它没有在我的命令提示符中显示当前分支。我认为这需要编辑，但我不知道要更改什么才能使其显示当前分支。请注意，我喜欢颜色和一般结构（即$在自己的行中），所以如果可能的话，我想保留它。

Modify the prompt string and add $(__git_ps1 " (%s)")somewhere.
修改提示字符串并在$(__git_ps1 " (%s)")某处添加。
For example, try typing this into Bash:
例如，尝试在 Bash 中输入以下内容：
export PS1="\[\e]0;\w\a\]\n\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]$(__git_ps1 ' (%s)')\n$"
Once you find something you like, add that line to one of Bash's startup files, e.g. $HOME/.bashrc.
找到喜欢的内容后，将该行添加到 Bash 的启动文件之一，例如$HOME/.bashrc.
The source for git-prompt.shis well-commented and worth browsing if you're curious about other options.
如果您对其他选项感到好奇，的来源git-prompt.sh得到了很好的评论，值得浏览。
Note that you may have to manually source path/to/git-prompt.shbefore this will work. If so, add this line to your config file as well, above the export PS1bit.
请注意，您可能必须手动操作source path/to/git-prompt.sh才能使用。如果是这样，请将此行也添加到您的配置文件中，export PS1在位上方。
