yg.t_bc = template.new[==[/[[${name}]] ]==]
yg.t_bcsub = template.new[==[-[[${name}]] ]==]

function yg.breadcrumbs(path)
  local mypage = path or editor.getCurrentPage()
  local parts = string.split(mypage,"/")
  local crumbs = {}
  for i,part in ipairs(parts) do
    local current = ""
    for j=1,i do
      if current ~= "" then
        current=current.."/"
      end
      current = current..parts[j]
    end
      table.insert(crumbs, {name = current})
  end
  return crumbs
end

function yg.bc(path)
  return "[[home]]"..(template.each(yg.breadcrumbs(path),yg.t_bc)).." "..(template.each(yg.children(path),yg.t_bcsub)) 
end

function compareDate(a, b)
  print(a.lastModified  > b.lastModified )
  return a.lastModified  > b.lastModified 
end


function yg.children(path)
  local crumbsChildren = {}
  local mypage = path or editor.getCurrentPage()
  for page in each(table.sort(space.listPages(), compareDate)) do
   --print(mypage,page.name,string.find(page.name,mypage) )
    if (string.find(page.name,mypage) and mypage ~= page.name and #crumbsChildren <7)
    then
          table.insert(crumbsChildren, {name = page.ref})
    end
  end
  return crumbsChildren
end

parent and last 7 modified children are visible in breadcrumbs.
