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

## How to generate documents
 - `typedoc /path/to/src1 [/path/to/another/src/or/.js ...]`
the generated page will be stored in `/docs`.

   - set the referee source to my repo:
   - `typedoc --sourceLinkTemplate "https://git.kianting.info/?p=clo;a=blob;f={path};hb=HEAD#l{line}" /path/to/src1 ...`

store the documents
 - `rsync /path/to/docs host@/var/www/docs`
