• can any body tell me what is the diffenence between macro and preprocess?

• with the setteing and disable c/c++ externion

   "editor.tokenColorCustomizations": {
       "textMateRules": [
           {
               "scope": [
                   "entity.name.function.preprocessor",
                   "entity.name.variable.preprocessor.symbol.cs",
               ],
               "settings": {
                   "foreground": "#be5c44",
                   "fontStyle": ""
               }
           },
           {
               "scope": [
                   "meta.preprocessor.macro",
               ],
               "settings": {
                   "foreground": "#c70060",
                   "fontStyle": ""
               }
           },
       ]
   }

  it shows as: Orange(preprocess) and red (macro)
  

• but enable c/c++ extension; it shows as： all orange( why all is preprocess?)
  

• then enable semanticTokenColorCustomizations

    "editor.semanticTokenColorCustomizations": {
        "enabled": true,
        "rules": {
            "macro": {
                "foreground": "#0d5f14",
                "bold": false,
                "italic": false,
                "fontStyle": "",
                "underline": false
            },
            "preprocessor": {
                "foreground": "#ec3011",
                "bold": false,
                "italic": false,
                "fontStyle": "",
                "underline": false
            },
        }
    }

all green(macro)*why all is preprocess?):

Our extension doesn't provide any semantic colorization for "preprocessor" rules, just "macro" (see https://github.com/microsoft/vscode-cpptools/blob/main/Extension/package.json#L4130). You can change "C_Cpp.enhancedColorization" to "Disabled" to see the previous behavior, but that is not recommended. The previous red colors from the lexical colorization will also appear in an #else where IntelliSense is not active.

Our extension doesn't provide any semantic colorization for "preprocessor" rules, just "macro" (see https://github.com/microsoft/vscode-cpptools/blob/main/Extension/package.json#L4130).

so, is it necessary to add preprocessor semantic colorization?

[sean-mcmanus]

We don't currently support a "preprocessor" semantic token scope. It's not a standard token type: https://github.com/Microsoft/vscode-docs/blob/main/api/language-extensions/semantic-highlight-guide.md . And also our IntelliSense engine doesn't generate a semantic token of that type (even if we were to add a custom token type for it).
