展示HN：我用C语言构建了一个简约的类Forth栈解释器库
这个周末我创建了 stacklib.h —— 一个单头文件库，将 Forth 风格的栈操作引入 C 语言。它实现了一个基本的解释器，包含以下功能：
- 栈操作（push/pop/dup/swap/over/drop）
- 算术运算（+, -, *, /）
- 输出（., emit, cr）
- 栈检查（.s, depth）
示例用法：
```c
Stack s;
stack_init(&s);
dict_init();
exec(&s, "10 20 + ."); // 输出 "30"
exec(&s, "1 2 3 4 .s"); // 显示栈内容
```
这个库是自包含的，不需要任何依赖，并且处理基本的错误检查。它的灵感来源于想要理解 Forth 的基本工作原理，同时保持 C 语言的简单性。
我很好奇其他栈式或连接式编程爱好者对这种方法的看法。还有其他人构建过类似的东西吗？你会添加哪些功能以使其更有用？

This weekend I created stacklib.h - a single-header library that brings Forth-style stack operations to C. It implements a basic interpreter with:<p>- Stack operations (push/pop/dup/swap/over/drop)
- Arithmetic (+, -, *, /)
- Output (., emit, cr)
- Stack inspection (.s, depth)<p>Example usage:
Stack s;
stack_init(&s);
dict_init();
exec(&s, "10 20 + ."); // Prints "30"
exec(&s, "1 2 3 4 .s"); // Shows stack contents<p>The library is self-contained, requires no dependencies, and handles basic error checking. It was inspired by wanting to understand how Forth works at a fundamental level while keeping the simplicity of C.<p>I'm curious what other stack-based or concatenative programming enthusiasts think about this approach. Has anyone else built something similar? What features would you add to make it more useful?<p>GitHub: <a href="https://github.com/Ferki-git-creator/stacklib" rel="nofollow">https://github.com/Ferki-git-creator/stacklib</a>
