git_stats统计工具：统计小伙伴们的git代码提交

工具选型

git统计工具可选并不多，找了许久，在找到以下几个：

• GitStats, git history statistics generator: http://gitstats.sourceforge.net/, https://github.com/dmitryn/GitStats
• git_stats, a git repository statistics generator: https://github.com/tomgi/git_stats
• git-stats, Local git statistics including GitHub-like contributions calendars: https://github.com/IonicaBizau/git-stats
• gitinspector, The statistical analysis tool for git repositories: https://github.com/ejwa/gitinspector

经过一番比较，最终选择了git_stats，主要有以下几个好处：

• 相对较新，输出样式最讨人喜爱；
• 功能齐全，可与gitstats一拼；

为方便与CI集成，打成docker镜像 goodideal/docker-git-stats:latest，维护地址为：https://github.com/goodideal/git_stats

git_stats使用方法

git_stats使用方法非常简单，摘出帮助供参考：

$ git_stats help generate
Usage:
  git_stats generate

Options:
  p, [--path=PATH]                          # Path to repository from which statistics should be generated.
                                            # Default: .
  o, [--out-path=OUT_PATH]                  # Output path where statistics should be written.
                                            # Default: ./git_stats
  l, [--language=LANGUAGE]                  # Language of written statistics.
                                            # Default: en
  f, [--first-commit-sha=FIRST_COMMIT_SHA]  # Commit from where statistics should start.
  t, [--last-commit-sha=LAST_COMMIT_SHA]    # Commit where statistics should stop.
                                            # Default: HEAD
  s, [--silent], [--no-silent]              # Silent mode. Don't output anything.
  d, [--tree=TREE]                          # Tree where statistics should be generated.
                                            # Default: .
  c, [--comment-string=COMMENT_STRING]      # The string which is used for comments.
                                            # Default: //

Generates the statistics of a repository

应打包成了docker镜像，运行命令如下：

$ docker run --rm -v GIT_PATH:/git:ro -v OUTPUT_PATH:/gitstats goodideal/docker-git-stats:latest

其中挂载了2个目录：

• GIT_PATH git目录路径
• OUTPUT_PATH 统计输出路径
