Get git commit timmings

git-minutes.rb

require 'time'
 
data = `git log | grep "^Date"`.split($/).
        map { |line| Time.parse(line.split(' ')[4]) }.
        group_by { |x| x.hour }
  
data.each { |k, v| data[k] = data[k].size }
total_commits = data.values.inject(0) { |sum, x| sum += x }
data = data.sort { |a, b| a[0] <=> b[0] }
 
  
 puts "|---------------------------------"
 puts "| Total commits: #{total_commits.to_s.ljust(17)}"
 puts "|---------------------------------"
 puts "| Hour | #of Commits | %of Commits"
 puts "|---------------------------------"
  
data.each do |k, v|
    puts "| #{k.to_s.ljust(5)}|#{v.to_s.center(13)}| #{"%.3f"%((v*100.0)/total_commits)}"
end                                                                                                                                                   
          

.sort.group_by { |x| x.hour } should just be written as .group_by { |x| x.hour }. sort is unnecessary

Good catch @newacct, thanks.
