GNU bc ,一個計算器

比计算器高级多了,一个 DSL 语言

它可以定义函数可以用循环可以判断分支
但和数学一样基本没有类型概念也不能怎么操作字符串

倒是 Bison 被 GNU 喊得是要死了一样,在等维护者

GNU 家的 APL 解释器去年都更过,看来他们基本不缺贡献者

(其实就是没人用 MRI Ruby 也要用的,不知道现在 2.6 换 Yacc 没有
说句题外话我上周才知道 MRuby 是基于 Ruby 1.9 开发的,就是第一个基于字节码解释的版本,不过我没有验证

只知道 BeOS 那个传说纯矢量图的操作系统(
其实这么说有点有失公正了,因为操作系统不全是做 GUI 的
#include <stdio.h>
#include <jit/jit.h>

jit_context_t context;

jit_int result;

/* Create a context to hold the JIT's primary state */
context = jit_context_create();

jit_context_build_start(context);

/* Build the function signature */
params[0] = jit_type_int;
params[1] = jit_type_int;
params[2] = jit_type_int;
signature = jit_type_create_signature

/* Create the function object */
function = jit_function_create(context, signature);
jit_type_free(signature);

/* Construct the function body */
x = jit_value_get_param(function, 0);
y = jit_value_get_param(function, 1);
z = jit_value_get_param(function, 2);
temp1 = jit_insn_mul(function, x, y);
temp2 = jit_insn_add(function, temp1, z);
jit_insn_return(function, temp2);

/* Compile the function */
jit_function_compile(function);

/* Unlock the context */
jit_context_build_end(context);

/* Execute the function and print the result */
arg1 = 3;
arg2 = 5;
arg3 = 2;
args[0] = &arg1;
args[1] = &arg2;
args[2] = &arg3;
jit_function_apply(function, args, &result);
printf("mul_add(3, 5, 2) = %d\n", (int)result);

/* Clean up */
jit_context_destroy(context);

}
所以要手动使用特殊展开模式 (tailrec ...)
