创建序列图生成器 ruby​​ gem

问题描述

所以我想创建一个类似于 VCR 的 gem 开始记录方法调用连同这些方法所在的类，甚至可能是行号，并停止记录并生成一个 yml 文件或其他实际上是运行的 UML 序列图元数据描述的内容.

进一步扩展，我想使用美人鱼宝石来实际吐出一张图片 UML 图.

我正在考虑采用这篇 reddit 帖子中概述的方法，基本上是存储一组哈希值以解析为下游的某种植物文本.

So I want to create a gem similar to VCR that starts recording method callsalong with the classes those methods are in, maybe even line number, and stop recording and generate say a yml file or something which is effectively a UML sequence diagram metadata description of the run.

Extending that even further, I want to use the mermaid gem to actually spit out a picture UML diagram.

I'm thinking of taking the approach outlined in this reddit post, basically storing a array of hashes to parse into some kind of Plant text downstream.https://www.reddit.com/r/ruby/comments/11ns2l/does_a_uml_sequence_diagram_generation_gem_exist/

Anyways, finally, my question is... Is there a better way to approach this?Or should I just kind of follow the idea proposed in the reddit?

解决方案

A simplest solution would be to generate a plant uml file. A Plant file is far simpler than an XMI file and Plant is integrated in a lot's of tool.

It could be an alternative.

plantUML

For example:

@startuml
Alice -> Bob: Authentication Request
Bob --> Alice: Authentication Response
Alice -> Bob: Another authentication Request
Alice <-- Bob: another authentication Response
@enduml

produces:
