yUML extension for Visual Studio Code. Allows the creation of offline UML diagrams based on the yUML Syntax.

• Syntax highlighting of .yuml files
• Currently, the following diagram types are supported:
  • Class
  • Activity
  • Use-case
  • State
  • Deployment
  • Package
  • Sequence
    See the corresponding github project for the updated features
• Update of yUML diagrams after each file save
• Additional directives for altering diagram type and orientation
• Embedded rendering engine: No need to call an external web service
• Automatic sensing of light and dark themes
• Code snippets with samples of each diagram
• Integrated Markdown support

Please refer to the wiki page

Once a .yuml file is open, the viewer window can be invoked in two ways:

• By opening the command pallete and [partially] typing: view yuml diagram (see the screenshot above)
• By clicking the preview icon in the editor title area (see below)

There is a snippet for each diagram type. Just start typing one of the available diagram types: class, activity, usecase, state or deployment, package, sequence and a full example will be pasted into the yuml file.

yUML code can now be embedded into markdown documents by using the fencing syntax, as shown:

The yUML diagram will be directly rendered in the markdown preview window.

A topbar will show some useful links when hovered (see below), for accessing the wiki page, writing a review, reporting bugs and requesting new features.
