前言
本文介绍的是利用Python实现的一个小工具,用于分析Git commit log,获得Git Project每个成员的简单行为数据。
Warning:代码量不能代表程序员能力水平!
启动参数
共5个。
- Repo地址
- Commit 起始日期
- Commit 结束日期
- Git仓库子目录
- 统计分析结果CSV文件目标路径
exec_git
Git Log命令:
git -C {} log --since={} --until={} --pretty=tformat:%ae --shortstat --no-merges -- {} > {}
填入参数,调用系统命令'os.system()',输出结果至本地临时文件。读取至内存,简单的String Array。
parse
Git Log输出有3种格式,对应3种正则表达式。
REPATTERN_FULL = r"\s(\d+)\D+(\d+)\D+(\d+)\D+\n" REPATTERN_INSERT_ONLY = r"\s(\d+)\D+(\d+)\sinsertion\D+\n" REPATTERN_DELETE_ONLY = r"\s(\d+)\D+(\d+)\sdeletion\D+\n"
遍历得到的数据,首先构造一个以Author为Key,分析结果为Value的字典。
分析结果构造一个元祖,包括:
- Commit 次数
- 增加代码行数
- 删除代码行数
- 变更代码行数
save_csv
简单省略。
示例代码:
