Snobol4 语言 将 CSV 转换为 JSON 数组

阿木博主一句话概括：Snobol4^【1】 语言实现 CSV^【2】 到 JSON^【3】 数组的转换：代码解析与技巧

阿木博主为你简单介绍：
Snobol4 是一种古老的编程语言^【4】，以其简洁和强大的文本处理^【5】能力而闻名。本文将探讨如何使用 Snobol4 语言将 CSV（逗号分隔值）文件转换为 JSON（JavaScript 对象表示法）数组。我们将从 Snobol4 的基本语法开始，逐步深入到实现 CSV 解析和 JSON 构建的细节，并提供一些实用的代码示例。

一、
CSV 和 JSON 是两种常用的数据交换格式^【6】，它们在数据存储、传输和处理中扮演着重要角色。CSV 格式简单，易于阅读和编辑，而 JSON 格式则更加灵活，易于机器解析。本文将展示如何利用 Snobol4 语言，这一在文本处理方面具有独特优势的语言，来实现 CSV 到 JSON 数组的转换。

二、Snobol4 语言简介
Snobol4 是一种高级编程语言，由 Stephen C. Johnson 在 1962 年设计。它以其强大的字符串处理^【7】能力而著称，特别适合于文本处理任务。Snobol4 的语法简洁，易于理解，但同时也具有一定的挑战性。

三、CSV 文件格式解析
CSV 文件由逗号分隔的值组成，每行代表一个记录^【8】，每个字段^【9】由逗号分隔。在 Snobol4 中，我们可以使用其内置的字符串处理函数来解析 CSV 文件。

四、JSON 数组构建
JSON 数组是一系列由逗号分隔的值，可以是字符串、数字、布尔值或对象。在 Snobol4 中，我们需要构建这样的数组结构^【10】，并将其转换为字符串。

五、Snobol4 代码实现
以下是一个简单的 Snobol4 程序，用于将 CSV 文件转换为 JSON 数组。

```snobol
:readfile
'csvfile' open readfile
'jsonfile' open writefile
'line' getline readfile
'json' put '[]' writefile
'comma' put ','

'bracketclose' put ']'
