Subject: yabm update

Updated:

1. Add split function -- time not counted into the total:

  bm.log("label",:split)

whenever the second parameter is not nil, this time slice is separate from 
the total.

2. Added sort by time used (longest -> shortest)
3. Changed output layout
4. Added to RAA

Code...

class Yabm
  def initialize
    @total=0
    @spare=0
    @cp=[[nil,Time.now,0]]
  end
  def log(label=nil,split=nil)
    @cp << [label,Time.now,split]
  end
  def report
    elapsed=[]
    @cp.each_index do |i|
      if @cp[i][0]!=nil then
        if @cp[i][2] then
	  @spare+=@cp[i][1]-@cp[i-1][1]
	else
	  @total+=@cp[i][1]-@cp[i-1][1]
	end
        elapsed << [@cp[i][0],@cp[i][1]-@cp[i-1][1],@cp[i][2]]
      end
    end
    elapsed.sort! do |x,y| y[1] <=> x[1] end
    if @spare==0 then
      caption=sprintf "Time used (sec.): %0.3f",@total
    else
      caption=sprintf "Time used (sec.): %0.3f / %0.3f",@total,@total+@spare
    end
    print "\n",caption,"\n"
    print "-"*caption.length,"\n"
    elapsed.each do |e|
      if e[2] then
	printf "%0.3f (----) -- %s\n",e[1],e[0]
      else
	printf "%0.3f (%0.1f%%) -- %s\n", e[1],e[1]/@total*100,e[0]
      end
    end
  end
end
