The title says it all...

Following Issues might be:

• Display Errors
• Check Model
• Code Completion

Please notify me, when you have done the first tests, connecting to the VS Code client as I would like to close #40 , once I can be sure that the implementation is correct. Any further problems concerning specific features should then become separate issues in MopeSWTP-SS21/vs-code-client.

I have not worked on this Issue yet.

I just connected the VsCode Client to our MopeServerJar.
This was pretty easy because i just had to follow the steps in the readme.
The only problem i had was that pressing F5 just triggered a build but didn't open another vscode window with the Extension running...
Propably because i forgot the Save Workspace As in this step:

• Create a VS Code project that has the working copy of this repository as the only workspace folder (this is needed, because the repo contains a .vscode folder with settings that are required to test the extension). You can do this with the following steps:
  • Open a new window in VS code.
  • Select File -> Add folder to workspace ...
  • Add the folder containing this repository and save the workspace using File -> Save Workspace As ...

I then tried File -> Open Folder and selected the VsCodeClientRepo. This worked:)

After Connecting to the Server i received a Message "Hallo vom Server" and could see that the InitializationRequest was triggered.

However none of the other Commands worked.
loadModel is connected to this #85
Completion probably didn't work because our Mope Server does not publish any capabilities...

So the next Step for me is to publish some Server Capabilities.
There will be a new Issue for this (see #91)

After Publishing CompletionCapabilities, I managed to complete Something:)

However there are some Major Issues:(

1. My "SymbolLimiter" does not work as expected because it does not stop at Whitespaces...
2. Much bigger Problem: The Server can only read stuff from the File if it is saved. This makes Completion not very user friendly...

[manuEbg]

I think we need to implement the DidChangedTextDocument-Notification and DidOpenTextDocument-Notification to maintain some ShadowFiles for the Server.

[CSchoel]

Yeah, I think you are right on track with your analysis. 👍 Keep in mind that you might have to tell the client how you want to synchronize unsaved document updates.

After the Workaround or Fix #85 (comment) i was able to load a Model from VSCode.
And i was able to not load a Model but see Diagnostics:) Somehow there seems to be a LineCharacterConfusionIssue...

[CSchoel]

Can you double-check ...

• which file is loaded by the OMC and what are its contents,
• and what is the raw error message reported by the OMC?

On my machine, OMShell reports the following:

>> loadModel(SyntaxError); getErrorString()
false
"[/home/cslz90/Documents/Promotion/code/MoST/test/res/SyntaxError.mo:6:3-6:3:writable] Error: Missing token: SEMICOLON
Error: Failed to load package SyntaxError (default) using MODELICAPATH /usr/bin/../lib/omlibrary:/home/cslz90/.openmodelica/libraries/:/home/cslz90/Documents/Promotion/code/MoST/test/res.
"

This is what I would expect, since the error is on the first token that comes after the position where the semicolon should be (6:3).

Actually, now that I see the numbers... could it be that you just have a one-off error in your line and column indices?

[manuEbg]

You are right. The Error is in fact located in 6:3.
The Diagnostic published by the MopeServer also contains 6:3

DiagnosticLocation: /home/swtp/modelica/exampleModels/SyntaxError.mo
Diagnostics: 
Diagnostic [
  range = Range [
    start = Position [
      line = 6
      character = 3
    ]
    end = Position [
      line = 6
      character = 3
    ]
  ]
  severity = Error
  code = null
  codeDescription = null
  source = null
  message = "Error: Missing token: SEMICOLON\n"
  tags = null
  relatedInformation = null
  data = null
]

The VSCodeClient seems to increment the received Position
