eclipse - VS Code : How to set semantic syntax coloring like Eclipse does. 默认语法着色不这样做

Question

在 C/C++ 中，在 Eclipse 编辑器中，您可以在更多语言级别设置颜色:
例如函数参数，局部变量可以有不同的颜色。
可以更改静态和全局变量颜色。可以配置宏和宏引用。

如何在 Visual Studio Code 中做到这一点？我不确定 text mate tmLanguage 是否可以实现这一点。我找不到任何文档。

您不仅限于主题提供的语义标记突出显示。您可以通过执行以下操作为支持的语言语义标记自己选择颜色和字体样式:

It's also possible to define semantic theming rules in the user settings:

"editor.tokenColorCustomizationsExperimental": {
    "property.readonly": {
        "foreground": "#35166d"
    },
    "*.defaultLibrary": {
        "fontStyle": "underline"
    }
}

并特别查看 https://github.com/microsoft/vscode/wiki/Semantic-Highlighting-Overview#how-can-i-find-out-what-semantic-tokens-are-available-and-how-they-are-themed关于如何发现语义标记。例如:



如果没有 semantic token type列出，该语言服务尚不支持它们。但毫无疑问，当他们这样做时，您会想要修改他们的一些颜色和字体样式选择。

vscode 1.45 将重命名 editor.tokenColorCustomizationsExperimental至 editor.semanticTokenColorCustomizations
见 https://github.com/microsoft/vscode/issues/96267

此语法在 Insiders' Build 2020 年 4 月对我有用:

"editor.semanticTokenColorCustomizations": {
    "enabled": true,
    "rules": {
        "enumMember": "#ff0000"
    },
    "[Default Dark+]": {
        "enabled": true,
        "rules": {
            "variable.readonly": "#ff00ff"
        },
    }
},

来自 https://github.com/microsoft/vscode-docs/blob/vnext/release-notes/v1_45.md#semantic-token-styling-in-the-user-settings :

Semantic coloring is available for TypeScript and JavaScript, with support for Java, C++ in the works. It is enabled by default for built-in themes and being adopted by theme extensions.

The editor.semanticTokenColorCustomizations allows users to overrule the theme settings and to customize the theming.

Example that adds semantic styling to all themes: ```

"editor.semanticTokenColorCustomizations": {
    "enabled": true,
    "rules": {
        "property.readonly": {
          "foreground": "#35166d"
        },
        "*.defaultLibrary": {
            "bold": true
        }
    }
}

The setting above colors all constants with #35166d and all occurrences of symbols from a default library (e.g. Math, setTimeout) bold.

Example that adds semantic styling to the Dark+ themes: ```

"editor.semanticTokenColorCustomizations": {
    "[Default Dark+]": {
        "enabled": true,
        "rules": {
            "parameter": { "underline": true },
            "*.declaration": { "bold": true }
        }
    }
}

The setting above underlines all parameters in the Dark + theme and
makes all symbol declarations bold.

Theming for semantic tokens is explained in more details in the
[Semantic Highlighting
Guide](/api/language-extensions/semantic-highlight-guide#theming).

奇怪的是，在我的测试中，即使使用 enabled: true在上面"editor.semanticTokenColorCustomizations"您仍然需要启用此设置:

    "editor.semanticHighlighting.enabled": true

但这是默认设置。
