Snobol4【1】 语言实战：Markdown【2】 标题转 HTML【3】 标签

Snobol4 是一种古老的编程语言，它最初在1962年由David J. Farber、Peter J. Deutsch 和 James E.ystein 在贝尔实验室开发。尽管 Snobol4 在现代编程语言中并不常见，但它仍然具有一定的学术价值和历史意义。本文将围绕 Snobol4 语言，通过一个实际案例——Markdown 标题转 HTML 标签，来探讨 Snobol4 的编程技巧和应用。

Markdown 标题转 HTML 标签的背景

Markdown 是一种轻量级标记语言，常用于格式化文本。Markdown 中的标题通常使用 `` 符号来表示，例如：


一级标题
二级标题
三级标题

而 HTML 标签则用于网页内容的结构化，其中标题标签【4】为 `` 到 ``，分别对应从一级到六级标题。

将 Markdown 标题转换为 HTML 标签，可以帮助我们更好地将 Markdown 文档转换为网页内容，提高文档的可读性和可访问性。

Snobol4 语言简介

Snobol4 是 Snobol 系列编程语言的第四个版本，它以其强大的字符串处理【5】能力而闻名。Snobol4 提供了丰富的字符串操作函数，如搜索、替换、匹配等，这使得它在处理文本数据时非常高效。

下面是一个简单的 Snobol4 程序示例，用于打印 "Hello, World!"：

snobol
PUT 'Hello, World!'
PUT !CR
PUT !LF

实战：Markdown 标题转 HTML 标签

1. 确定输入和输出格式

输入：Markdown 标题字符串，例如 ` 一级标题`
输出：对应的 HTML 标签字符串，例如 `一级标题`

2. 编写 Snobol4 程序

以下是一个 Snobol4 程序，用于将 Markdown 标题转换为 HTML 标签：

```snobol
PUT【6】 'Markdown标题字符串'
PUT !CR
PUT !LF
