One Editor.
Design and Code.
A SysMLv2 Editor for VSCode Developers.
Bridging the gap between modeling and code.
Key Features
Syntax Highlighting
Syntax highlighting uses colors to distinguish language elements such as keywords, strings, and comments. It improves code readability, helps you spot syntax errors more easily, and enhances overall code comprehension - leading to more efficient development.
Syntax Checking
This feature automatically validates your code against language grammar rules, detecting typos and syntax errors in real time. Issues are displayed as warnings or errors, helping you catch bugs early and boost productivity.
Navigate to Definition
Quickly jump to the declaration of a variable, reference, or other symbol by placing your cursor on it. Instantly navigate to its source to review the implementation - streamlining code navigation, understanding, and editing.
Outline View
The Outline view provides a structured overview of your code, giving you quick access to key elements and improving navigation. It helps you grasp the structure of your model or script at a glance.
Automatic Diagram Generation (Optional)
This feature automatically generates diagrams based on the model described in your file. The visuals include representations of actions and messages, providing an intuitive way to visually understand the structure and behavior of your models.
- You can display the diagram by running “View Diagram” from the Command Palette (Windows/Linux: [Ctrl] + [Shift] + [P], macOS: [Command] + [Shift] + [P]) or by using the shortcut (Windows/Linux: [Ctrl] + [Shift] + [V], macOS: [Command] + [Shift] + [V]).
