additionalTextAttributes marked with @ApiStatus.Internal, how to provide additional colors to color schemes?

Hi,

Could you please clarify what the problem is?

Only the extension point bean is internal, which shouldn't affect its usage.

Hi,

In my plugin.xml file, the tag for the additionalTextAttributes label shows a tilde prompt, indicating that this is an Internal API, although it does not affect the functionality implementation. I know that Internal APIs should not be used, but the official documentation guides me to use this label, and I cannot find a suitable alternative to achieve the same functionality.

What I really want to know is whether this label is available. If it is not available, what should be used as a substitute? If it is available, is the tilde prompt misleading and does it need correction?

To add additional colors to color schemes, you can extend the existing color scheme by implementing the EditorColorsScheme interface or using a custom TextAttributesKey. Define your custom colors in the plugin's XML and register them in plugin.xml. Since @ApiStatus.Internal elements aren't intended for public use, avoid relying on them for production code. Instead, use the officially supported APIs for customization.

Hi,

I can't reproduce this.

Could you please share your sources to reproduce it and provide information about the IDE you use for developing the plugin?

additionalTextAttributes is marked as @ApiStatus.Internal, so it's not intended for public use. To add custom colors, you should define your own TextAttributesKey and register it in the ColorSettingsPage via AttributesDescriptor. This ensures compatibility with color schemes without relying on internal APIs.

The additionalTextAttributes field is marked with @ApiStatus.Internal, meaning it’s not meant for public use and could change or be removed in future updates. Instead of relying on internal APIs, you should define your own TextAttributesKey and register it in the ColorSettingsPage using an AttributesDescriptor. This approach ensures better compatibility with IDE color schemes and follows the recommended practices for extending syntax highlighting in IntelliJ-based IDEs. By avoiding internal APIs, your plugin remains stable across different versions of the IDE.
