Python实现一个Git日志统计分析的小工具

时间:2022-11-09 21:56:06

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:

?
1
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。

?
1
2
3
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。
