Snobol4【1】 语言实战：实现日志性能分析系统【2】

Snobol4 是一种古老的编程语言，最初于1962年由David J. Farber和Ralph E. Griswold设计。它以其强大的字符串处理能力而闻名，尽管在现代编程语言中并不常见，但在某些特定领域，如文本处理和数据分析，Snobol4 仍然有其独特的应用价值。

本文将探讨如何使用 Snobol4 语言实现一个简单的日志性能分析系统。我们将通过一系列的 Snobol4 代码片段，展示如何读取日志文件、提取关键信息、计算性能指标，并最终生成分析报告【3】。

系统设计

我们的日志性能分析系统将包括以下功能：

1. 读取日志文件。
2. 提取日志中的关键信息，如时间戳【4】、请求类型【5】、响应时间【6】等。
3. 计算性能指标，如平均响应时间【7】、请求成功率【8】等。
4. 生成分析报告。

代码实现

1. 读取日志文件

我们需要编写一个 Snobol4 程序来读取日志文件。以下是一个简单的示例：

snobol
:IN FILE
IN FILE
READ FILE
END FILE

这段代码将打开一个名为 `FILE` 的文件，并读取其内容。`IN FILE` 和 `END FILE` 是 Snobol4 的输入和输出控制语句。

2. 提取关键信息

接下来，我们需要从日志中提取关键信息。以下是一个示例，展示了如何提取时间戳和请求类型：

```snobol
:IN FILE
IN FILE
READ FILE
WHEN $1 = "Request" THEN
