analyse-git-commit-count

INTRO

最近捣鼓出一个小工具, 用来分析某个git仓库里所有人的commit, 看看某个人在这个仓库里做过多少提交

虽然统计结果不可能完全准确, 但是足够满足好奇心了

核心: git shortlog --summary --numbered --email --all

# cd to any git repo
ruby $ABS_PATH/analyse-git-info.rb | uplot bar -o -d, -t "Git commit count of user"

TODO

  • 这个小工具做成gem
  • 用rspec写测试(练习…)
  • 怎么能使得它接收 stdin 也能正常工作呢?
