Semantic tokens not working with Clojure LSP

[prcastro]

Describe the bug
I'm trying to setup LSP and my editor doesn't recognize s/defn macro as a function declaration.

The Clojure LSP should be reporting s/defn as function semantic tokens. Looking at the logs, the LSP plugin doesn't seem to be sending any semanticTokens/full requests. Also, adding:

{
    "rules": [
        {
            "scope": "meta.semantic-token",
            "background": "#00000101"
        },
    ]
}

To the color scheme also does nothing.

To Reproduce
Open a clojure project with prismatic schema and clojure-lsp set up. Declare a function using s/defn.

Expected behavior
I expected defn and s/defn function definitions to be highlighted the same

Screenshots

Environment (please complete the following information):

• OS: macOS 13.4.1
• Sublime Text version: 4143
• LSP version: 1.24.0
• Language servers used: clojure-lsp

Additional context
I debugged this with the clojure-lsp dev and he was convinced the problem was on the client side (LSP)

Have you enabled "semantic_highlighting": true in the LSP settings? (it's false by default)

Can you place the cursor inside s/defn and select Tools > Developer > Show Scope Name from the menu - there should be a "Semantic Token" section in the popup, if semantic tokens are enabled.

Could you post the exact response to the initialize (1) request from the LSP log panel, so we can see the exact capabilities of the clojure-lsp server?

The docs are missing the part to set "semantic_highlighting": true
https://lsp.sublimetext.io/customization/#semantic-highlighting

It was indeed the "semantic_highlighting": true config missing. Maybe adding it to the documentation would make things more clear. Thanks for the help =D

And yes, clojure-lsp was announcing semantic tokens. On initialize I have:

'semanticTokens': {'requests': {'full': {'delta': True}, 'range': True},

And I have exactly one other log saying:

'semanticTokensProvider': {'full': True, 'legend': {'tokenTypes': ['namespace', 'type', 'function', 'macro', 'keyword', 'class', 'variable', 'method', 'event', 'interface'], 'tokenModifiers': ['definition', 'defaultLibrary', 'implementation']}, 'range': True}
