Quick start

In a browser (without local VSCode)

You can try out SysIDE Editor Legacy without needing to instal it locally. To do so:

1. Go to Visual Studio Code for the Web
2. Open the Extensions tab on the right of the screen
3. Search for and install SysIDE Editor Legacy
4. Open a folder or a .sysml file

This is a good way to get a taste for how SysIDE Editor Legacy works. But if you plan on using it for a longer term or for larger models, we suggest installing it locally.

Running locally

0. Install Visual Studio Code, VSCodium, or Cursor AI
1. Open the Extensions tab on the right of the screen
2. Search for and install SysIDE Editor Legacy
3. Open a SysML v2 (.sysml) file and the extension will activate.
4. Link with the SysML v2 standard library:

Standard library

SysIDE Editor Legacy includes the standard library from our fork of the SysML-v2-Release repository. The library is licensed under the LGPL v3.0, see LICENSE.

If you wish to use a different version of the standard library you can go to the SysIDE Editor Legacy settings and enter the path to the directory with your preferred library.

Features

The extension provides basic features to support SysML v2 document editing:

• Semantic and syntax checking identifies errors as they occur allowing to instantly correct mistakes and speed up workflow.
  
  
  

• Semantic highlighting increases readability and allows to distinguish different parts of the code quickly.
  
  
  

• Autocompletion speeds up the workflow by reducing typing errors and minimizing manual input.
  
  
  

• Hovers instantly display documentation allowing to quickly understand an element.
  
  
  

• Code navigation speeds up development by enabling quick access to element definitions.
  
  
  

• Folding improves readability and eases navigation by organizing code into collapsible sections.
  

• Auto-formatting enhances code readability and maintainability by ensuring consistent structure for:

  • Comment bodies
    
    
    

  • Elements
    
    
    

• Renaming saves time and reduces errors by renaming all elements with the same name with one click.
  
  
  

• References enable efficient navigation and code updating by identifying all instances of an element.
  
  
  

• Document symbols provide rapid model overviews, enabling efficient comprehension and navigation.
