Tshunhue 是什麼呢？

+

Tshunhue（河洛語：春花）是一個 Lisp 系的玩具程式語言。主要的特徵有：

+
+
    +

  • 不可變物件。

    • +

  • 閉包作為第一類物件。

    • +

  • 靜態型別。

    • +

  • 和型別 (Sum Type) 和積型別 (Product Type)。

    • +
+
+
+
+

其他

+
+

垃圾回收

+

先不實現垃圾回收。若是要實現垃圾回收，可以用引用記數。做一個這樣的表格：

+ ++++ + + + + + + + + +

記憶體位址

引用次數

0x12345

+

……

+

1

+

……

+
+

以下有一個範例：

+
(Type IntPair (IntPair Int Int))
+(def IntPair a (IntPair x y))
+
+; 這個時候我們可以呼叫引用計數增加函數 inc_ref_count()
+; inc_ref_count(&a);
+; inc_ref_count(&x);
+; inc_ref_count(&y);
+...程式碼
+; x 活著的程式碼區段結束時，呼叫引用記數減少函數 dec_ref_count()
+; dec_ref_count(&a);
+; dec_ref_count(&a[0]); // &x
+; dec_ref_count(&a[1]); // &y
+
+
+
+
+

實做方式

+

用 Python3 將原始碼轉成 AST，以 s-expression 表示。再進行型別推測後，進行閉包轉換，不進行 CPS 變換，利用 llvmlite 生成 LLVM IR。

+

需要的東西：

+
    +

  • llvmlite

    • +

  • python3

型別

+
+

簡單型別

+
+

數字

+
    +

  • int：整數，初期可用 64 位元帶符號整數處理。

    • +

  • dou：雙精度浮點數

    • +
+
+
+

字串

+
    +

  • str：字串

    • +
+

暫不支援 char。

+
+
+

布林

+
    +

  • bool：布林值。#t：真值，#f：假值。

    • +
+
+
+
+

複雜型別

+
+

自訂型別

+

可以自訂 product type 或 sum type。為求簡化，不支援型別當參數。

+
+
+(Type TYPE-NAME (Type-constronctor x1 x2 ...))
+
+ +
+
+(Type TYPE-NAME (U (Type-const1 x1 x2 ...)(Type-const2 x1 x2 ...)...))
+
+ +
+
+(Type TYPE-NAME (Type-constronctor))
+
+ +
+
+(Type TYPE-NAME (U (Type-const1)(Type-const2)...))
+
+ +

U 是 union 的意思，指 Sum Type。

+

例如：

+
(Type IntPair (IntPair Int Int))
+
+
+

如果可以模式匹配，就變這樣：

+
(\ ((IntPair x))
+  (match (x)
+    ((IntPair 7 9) 9)
+    ((IntPair 8 a) a)
+    ((IntPair x y) (+ x y))))
+
+
+

Sum Type 的用法：

+

(Type OrigColor (U (Red)(Green)(Blue))) ; 三原色

+

如果可以模式匹配，就變這樣：

+
(orig-color-to-str ((OrigColor x))
+  (match (x)
+    ((Red) "Red")
+    ((Green) "Green")
+    ((Blue) "Blue")))

基本函數介紹

+
+

四則運算

+
+
++ : (-> int int int)
+
+ +

整數相加。

+
+
+- : (-> int int int)
+
+ +

整數相減。

+
+
+* : (-> int int int)
+
+ +

整數相乘。

+
+
+/ : (-> int int int)
+
+ +

整數相除，得商數。除以 0 的時候跳出特例，中止程式。如果用 C 語言表示的話：

+
static jmp_buf buf;
+...
+void int_div_closure_thunk(Object* closure, Object* lhs, Object* rhs, Object* result){
+  if (lhs->value==0){
+      printf("Exception: Div 0 Error.");
+      longjmp(buf,1);
+  }
+
+}
+...
+int main(void){
+  int jmpVal = setjmp(buf);
+  if (jmpVal == 0){
+  // main_body
+  }else{
+  // exit the program with the exception
+  printf("Exit the program with the exception");
+  }
+}
+
+
+
+
++. : (-> dou dou dou)
+
+ +

浮點數相加。

+
+
+-. : (-> dou dou dou)
+
+ +

浮點數相減。

+
+
+*. : (-> dou dou dou)
+
+ +

浮點數相乘。

+
+
+/. : (-> dou dou dou)
+
+ +

浮點數相除。

+
+
+

布爾值

+
+
+and : (-> bool bool bool)
+
+ +

AND。

+
+
+or : (-> bool bool bool)
+
+ +

OR。

+
+
+not : (-> bool bool)
+
+ +

NOT。

+
+
+

流程控制

+
+
+(if cond then alt)
+
+ +

若 cond 為真則返回 then，否則返回 alt。

+
+
+

影印字元

+
+
+print-str : (-> str void)
+
+ +

列印字串。void 表示不返回任何東西。

+
+
+int-to-str : (-> int str)
+
+ +

整數轉成十進位字串（10 為 base）。

+
+
+dou-to-str : (-> int str)
+
+ +

浮點數轉成十進位字串（10 為 base）。

+
+
+

定義變數 (=)

+
+

非函數

+

語法如下：

+
(def Type var expression)
+
+
+

例如：

+
(def int a 10)
+(def dou b (+ 3.1 7.0))
+
+
+

..note

+
因為 tshunhue 裡面，所有變數都是不可變物件， ``define`` 不可以拿來重新設定值。定義閉包也一樣。
+
+
+
+
+

函數（閉包）

+

閉包的定義比較複雜。但大致如下：

+
(def Type var lambda-function)
+
+
+

例如：

+
(def (-> int int) int-add1 (\ ((int x)) (+ x 1)))
+(def (-> dou dou dou) sqrt-sum (\ ((dou x)(dou y)) (+. (*. x x) (*. y y))))
+
+
+
+
+
+

匿名函數 (lambda function)

+

定義：

+
+
+(\ () body+)
+
+ +
+
+(\ ((Type var)) body+)
+
+ +
+
+(\ ((Type1 var1)(Type2 var2)[...]*) body+)
+
+ +

所有函數都是第一類物件與閉包，用 lexical scope 保存前文變數。
