![]() Assuming a diagram is synchronized (i.e.Sirius works hard to ensure that what you see on you sequence diagram (in terms of vertical ordering of elements and horizontal ordering of lifelines) always correspond to the semantic ordering of the represented events. However placing a message above or below another one has a strong implication on the ordering of the events they represent, and thus on the structure of the underlying semantic model which is represented. This is true for the vertical placement and for the left-to-right order of lifelines. The relative graphical positions of elements on a sequence diagram have strong meaning. The most important consequence of this is that contrary to what happens on a classical diagram, The canonical case is a UML Sequence Diagram (where the notation comes from), which represents the messages exchanged between objects in a software system. Typically, they representĮvents sent and received between some entities over ![]() Obeo UML Behavioral viewpoint (available for free at ) which is based on the Eclipse Foundation’s UML2 meta-model.Īs their name says, sequence diagrams are meant to represent ordered sequences of elements. The resulting diagram is available in the the specification of a UML sequence diagram editor. This tutorial is based on an example, i.e. It has been written for software architects who want to specify sequence diagrams on their own meta-models. This document describes how to specify sequence diagram modelers with Sirius. output Defines output format.Sequence Diagrams Specifying Sequence Diagram Editors List of paths to the files or directories containing OVERVIEW: Generate PlantUML script and view it and diagram in browser Or to apply customizations during generation. This is especially helpful to use multiple source files as basis for the diagram. You can also use SwiftPlantUML as a command-line tool or Swift package. The class diagram will then be opened in your browser. You are able to generate a diagram from selected lines of code or from a whole file displayed in Xcode. I wanted to provide a tool for Swift developers written in Swift! This will hopefully allow me and potential contributors to work on future improvements faster and more efficiently.Īnd so I started working on SwiftPlantUML, a utility that is available as Xcode Source Editor Extension. And none of these tools are written in Swift :( Some of the projects are no longer maintained and are limited when it comes to functionality. For example, there areīut these tools require the user to manually install additional dependencies (e.g. ![]() There are already various open-source projects to address this process. How can this be done? By parsing the source code, transform it into a script conforming to the PlantUML Language and then use an online tool to generate the actual diagram. Let me point out PlantText, a well designed online tool to generate images based on the PlantUML Language Reference.īut back to Swift and the use case to generate a class diagram from existing Swift source code. There is a vibrant ecosystem around PlantUML. ![]() Then I discovered PlantUML which is an open-source tool to create various types of UML diagrams from a plain text language. It all started when I discovered and how easy it is to create sequence diagrams by combining text notation scripting and drawing by clicking and dragging in the same model. Textual modeling tools help me to more efficiently create and work with software diagrams. Visio or StarUML, are very flexible but I often find myself struggling to quickly draw the components relationship or other layout aspects. UML as a general-purpose, modeling language is easy to understand and represents a standard way to visualize the design of a system. I work on various software projects written in Swift and I frequently find myself in a situation where I have to create diagrams based on the premise of existing source code, either for documentation purposes or to explain the system design concept. ![]()
