Snobol4【1】 语言实战：JSON【3】 数组转 CSV【4】 行实战
Snobol4 是一种古老的编程语言【5】，最初在1962年由David J. Farber、Ralph E. Griswold 和 Ivan P. Polonsky 在贝尔实验室开发。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 已经不再流行，但它仍然是一个有趣的语言，可以用来解决一些特定的问题。本文将探讨如何使用Snobol4 将JSON数组转换为CSV格式。
JSON与CSV简介
JSON（JavaScript Object Notation）是一种轻量级的数据交换格式【7】，易于人阅读和编写，同时也易于机器解析和生成。JSON数据通常以键值对【8】的形式出现，例如：
json
[
{"name": "Alice", "age": 25},
{"name": "Bob", "age": 30}
]
CSV（Comma-Separated Values）是一种简单的文件格式，用于存储表格数据。CSV文件中的每一行代表一个数据记录，每个字段由逗号分隔。例如：
name,age
Alice,25
Bob,30
snobol【2】4 简介
Snobol4 是一种高级编程语言，特别适合于文本处理【9】。它具有以下特点：
- 强大的字符串处理能力
- 简洁的语法
- 丰富的文本处理函数【10】
实战：JSON数组转CSV行
在这个实战中，我们将使用Snobol4 编写一个程序，该程序能够读取JSON格式的数组，并将其转换为CSV格式的行。
步骤 1：解析JSON数组
我们需要解析JSON数组。在Snobol4 中，我们可以使用内置的字符串处理函数来解析JSON。
```snobol
:parsejson【11】
0 "name" 1 "age" 2 "value" 3 "end"
4 "end" 5 "end" 6 "end" 7 "end"
