Git中代码预检查 - 快车库

                                
    在git中，有一个脚本pre-commit可以在git comit之前，进行一些操作，比如对代码进行预检查等。
    本脚本，利用ubuntu自带的cppcheck对代码进行提交前预检查。检查有误，则不能提交。

使用方式如下：

1、安装cppcheck
sudo apt-get install cppcheck
2、将附件复制到项目中.git/hooks目录下并修改权限。 以cmos-qmlplugin-multimedia-photos为例，执行：
cp cmos-pre-commit 目录/cmos-qmlplugin-multimedia-photos/.git/hooks/
chmod 755 目录/cmos-qmlplugin-multimedia-photos/.git/hooks/cmos-pre-commit
3、将git自带的pre-commit.sample复制一份，并添加一行代码：
cp目录/cmos-qmlplugin-multimedia-photos/.git/hooks/pre-commit.sample  目录/cmos-qmlplugin-multimedia-photos/.git/hooks/pre-commit
echo "./cmos-pre-commit" >>目录/cmos-qmlplugin-multimedia-photos/.git/hooks/pre-commit


cmos-pre-commit的源码如下：
