Snobol4【1】 语言实战：URL【2】 域名【3】解析实战

Snobol4 是一种古老的编程语言【4】，最初由美国贝尔实验室【5】在1962年开发。它以其简洁的语法和强大的字符串处理【6】能力而闻名。尽管在现代编程中Snobol4 并不常见，但它在处理字符串和文本数据方面仍然有其独特的优势。本文将围绕Snobol4 语言，通过一个实际的例子——URL域名解析，来展示如何使用Snobol4 语言进行编程。

Snobol4 简介

Snobol4 是 Snobol（StriNg OBjects and symBols）语言的第四个版本。它是一种高级编程语言【7】，特别适合于文本处理【8】和字符串操作。Snobol4 的语法简洁，易于理解，但同时也非常强大。

Snobol4 的主要特点包括：

- 强大的字符串处理能力
- 简洁的语法
- 高效的运行速度【9】
- 内置的文本处理函数

URL 域名解析

URL（统一资源定位符）是互联网上用于定位资源的地址。域名是URL中的一部分，用于标识网站或服务器的名称。我们将使用Snobol4 语言编写一个程序，用于解析URL并提取域名。

解析思路

1. 读取URL字符串。
2. 使用Snobol4 的字符串处理函数，找到URL中的域名部分。
3. 输出域名。

Snobol4 代码实现

以下是一个简单的Snobol4 程序，用于解析URL并提取域名：

```snobol
:inurl
| "http://" | "https://" | "ftp://" | "www." | "." | "://" | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
| " " | " " | " " | " " | " " | " " | " " | " " | " " | " " |
