umls序列2

UML 序列图生成器 - 命令行工具，用于从源文本文件生成各种格式（SVG、PNG、JPG、PDF 等）的图表。

源代码：https ://github.com/pbauermeister/umlsequence2

（这是对 https://github.com/pbauermeister/umlsequence项目的纯 Python 重写，该项目本身基于 Diomidis Spinellis 的 umlgraph。）

源文本文件采用所谓的“umlsequence”语法。

Umlsequence 语法示例：

# objects definitions
E : # External Messages
T : t:thread
O : :Toolkit
P :

# messages and activations
E  -> T+ a1:run(3)
T  -> O+ run()
O        >callbackLoop()

# creation
O+ :> P  p:Peer

# message with response
O- => P  result=handleExpose()

# destruction
O  #> P

# deactivation
T- O-
