AdaCore.ada extension - all syntax highlighting is red

[rustyx]

For some reason when using the Monokai Mega theme, all of my .ads and .adb files are colored red. But there are no errors and the project is compiling fine.

How to fix it?

With Monokai Mega theme:

With default Dark+ theme:

Hello!

You can have a look at our documentation regarding syntax/semantic highlighting here: https://github.com/AdaCore/ada_language_server/wiki/Custom-colors-in-VS-Code

Basically it seems that you are missing a mapping for the Monokai Theme, so you'll need to add it yourself as explained in the documentation.

Thanks for the tip. For some reason I still can't change any identifier color. Changing "keyword" and "entity.name.operator" works. But e.g. "function" or "entity.name.function" doesn't seem to have any effect.

    "editor.tokenColorCustomizations": {
        "textMateRules": [
            {
                "scope": "keyword, function, entity.name.function",
                "settings": {
                    "foreground": "#569cd6"
                },
            },
            {
                "scope": "entity.name.operator",
                "settings": {
                    "foreground": "#cebff5",
                },
            },
        },
    }

Also specifying it under "rules" doesn't help.

    "editor.semanticTokenColorCustomizations": {
        "[Monokai Mega]": {
            "rules": {
                "namespace": "#C8C8C8",
                "type": "#4EC9B0",
                "class": "#4CD5E0",
                "enum": "#4CE099",
                "interface": {"foreground": "#4CD5E0", "italic": true},
                "struct": "#49D66A",
                "typeParameter": {"foreground": "#3E52EB", "italic": true},
                "parameter": {"foreground": "#9CDCFE", "italic": true},
                "variable": "#9CDCFE",
                "property": "#8F9DFF",
                "enumMember": "#93E6BE",
                "function": "#DCDCAA",
                "keyword": "#569cd6",
                "modifier": "#569cd6",
                "comment": "#6A9955",
                "string": "#ce9178",
                "number": "#b5cea8",
                "operator": "#C586C0",
            },
        },
    },

I think that the Monokai Mega forces the semanticTokenColorCustomizations, so the one you specify in your settings.json is not taken into account.

Selecting another theme works fine for me (e.g: the predefined Monokai theme), so it's an issue coming from the Monokai Mega extension itself unfortunately.

here's the source of the Monokai Mega theme. It doesn't apppear to use semanticHighlighting or semanticTokenColorCustomizations..

[AnthonyLeonardoGracio]

it sets semanticHighlighting to false explicitly, that explains the issue. I don't know how to solve this, you should probably ask them.
