之後的做法

  • 先做一個前處理註冊器，註冊下列的前處理
    • 中英文間距
    • 換行點
    • 空白轉為 [glue]
  • 前處理完成字串後，必須要：
    • 算出字元的Box
    • 利用 frame/box 資訊分行、分頁
    • 然後算出每個Box的x, y, page
    • 最後納入排版

排版語法

使用lisp表示，但其實是陣列

  (hglue 寬度 伸展值)
  (vglue 高度 伸展值)
  (bp 原始模式 斷行模式) ; breakpoint
  (nl) ; newline
  (em 數字)
  (ex 數字)
  (span {"font-family" : "Noto Sans" , "font-size" : 16 })
  (vbox 高度 內容)
