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，最初由美国贝尔实验室【4】在1962年开发。它以其简洁的语法和强大的字符串处理【5】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处理【6】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Snobol4 语言在文本处理方面的强大能力。

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，特别适合于文本处理。Snobol4 的语法简洁，易于理解，同时提供了丰富的字符串操作函数。

URL 域名解析需求

在互联网应用中，解析URL（统一资源定位符）是一个常见的任务。URL通常包含协议【7】、域名、路径、查询参数【8】等部分。我们的目标是使用Snobol4 语言解析URL，并提取出域名部分。

Snobol4 URL 域名解析代码实现

以下是一个使用Snobol4 语言实现的URL域名解析的示例代码：

```snobol
:parse-url
