No syntax highlighting on MacOs

👓 What did you see?

Plain text .feature file

✅ What did you expect to see?

Highlighted syntax in .feature file

📦 Which tool/library version are you using?

Cucumber 1.2.8

🔬 How could we reproduce it?

Steps to reproduce the behavior:

1. Install Cucumber 1.2.8 on VSCode 1.69.2 for MacOs Monterey
2. Reload VScode
3. Open a project either locally or via the popular Remote - Containers extension
4. Create a file called test.feature in a feature/ folder in the workspace's root
5. Select Cucumber as language mode from the right side of the bottom status bar
6. Acknowledge that syntax highlighting is still not applied

Can you please share the output from the logs? See CONTRIBUTING.md for details.

I seem to be having a similar issue, though in macOS itself rather than a remote container. In the output I see an error like this, right before syntax highlighting fails:

[Error - 7:00:59 PM] Request textDocument/semanticTokens/full failed.
  Message: Request textDocument/semanticTokens/full failed with message: Incomplete group: {"children":[]}
  Code: -32603 

Same error seen in 2 codebases.

The problem is in the remote container as well as on MacOs. My machine has an M1 chip.

I am afraid I am not able to give you the log as I am not seeing the Cucumber Language Server in the dropdown:

@BrianHawley I found out that the lack of syntax highlighting is due to the custom theme I am using.

[niccolomineo]

If you have a custom theme, the absence of syntax highlight can be fixed by enabling semantic highlighting via settings, like so:

    "[cucumber]": {
        "editor.semanticHighlighting.enabled": true
    },

You may then want to launch the "Developer: inspect token and scopes" command in the event some tokens are not colorized and you want to find out more about those.
