我之前从一些博客文章中获得了这个bash代码,它用于在我的提示中显示我当前的git分支和脏状态。将git从1.7.11.4更新为1.8.5.4后,它不再显示分支或脏状态。
以下是我的提示:
[~/some/project (master)↑⚡] ->
它显示了(当前的git分支),箭头表示我在遥控器之前,我应该推动,闪电意味着我有未完成的更改。
更新后,就是这样(没有对repo进行任何更改):
[~/some/project] ->
以下是我的.bash_profile代码:

if test $previous_return_value -eq 0
then
PS1="${prompt}➔ "
else

}
PROMPT_COMMAND=prompt_func
我对bash不是很好,所以有人能发现问题,或者有更好的解决方案吗?
我正在玩bash代码,但还是无法搞清楚。求助。

# On branch master
nothing to commit (working directory clean)
前面有一个前导#
。现在git 1.8输出相同的内容,除了没有#
。
所以我所要做的就是改变这些界限:
branch_pattern="^# On branch ([^${IFS}]*)"
remote_pattern="# Your branch is (.*) of"
diverge_pattern="# Your branch and (.*) have diverged"
为:
branch_pattern="^On branch ([^${IFS}]*)"
remote_pattern="Your branch is (.*) of"
diverge_pattern="Your branch and (.*) have diverged"
删除了#
,一切正常。

请注意,此模式仍然失败:
remote_pattern="Your branch is (.*) of"
新的git输出如下:
Your branch is behind 'origin/master' by 2 commits, and can be fast-forwarded.
Your branch is ahead of 'origin/master' by 1 commit.
因此模式应更改为:
remote_pattern="Your branch is (behind|ahead) "
