Which Git commit stats are easy to pull

Question

Previously I have enjoyed TortoiseSvn\'s ability to generate simple commit stats for a given SVN repository. I wonder what is available in Git and am particularly interested

Modify https://stackoverflow.com/a/18797915/3243930 . the output is much closed to the graph data of github.

#!/usr/bin/ruby

# takes the output of this on stdin: git log --numstat --prety='%an'

map = Hash.new{|h,k| h[k] = [0,0,0]}
who = nil
memo = nil
STDIN.read.split("\n").each do |line|
  parts = line.split("\t")
  next if parts.size == 0
  if parts[0].match(/[a-zA-Z]+|[^\u0000-\u007F]+/)
    if who
      map[who][0] += memo[0]
      map[who][1] += memo[1]
      if memo[0] > 0 || memo[1] > 0 
        map[who][2] += 1
      end
    end
    who = parts[0]
    memo = [0,0]
    next
  end
  if who
    memo[0]+=parts[0].to_i
    memo[1]+=parts[1].to_i
  end
end

puts map.to_a.map{|x| [x[0], x[1][0], x[1][1], x[1][2]]}.sort_by{|x| -x[1] - x[2]}.map{|x|x.inspect.gsub("[", "").gsub("]","")}.join("\n")
