Is there a setting to change the color of inlay hints?

[schungx]

The current color is too similar to the code text, making code harder to read. I'd prefer a much lighter color - you only need to read it when you want to know the type.

[SomeoneToIgnore]

Currently in VSCode, there's a way to change the text color using the rust_analyzer.inlayHint color setting for your theme:
https://github.com/rust-analyzer/rust-analyzer/blob/30eb458b4fa8adcecd8cbf731bd1cfa9a7a8b88b/editors/code/package.json#L504

There's a way to tweak hints' colors more, here are all possible options: https://vshaxe.github.io/vscode-extern/vscode/ThemableDecorationAttachmentRenderOptions.html , but this requires the code changes in here: https://github.com/rust-analyzer/rust-analyzer/blob/30eb458b4fa8adcecd8cbf731bd1cfa9a7a8b88b/editors/code/src/inlay_hints.ts#L46

Worked beautifully. Thanks.

Add the following to settings.json:

"workbench.colorCustomizations": {
    "rust_analyzer.inlayHint": "#bbbbbb"
},

Of course, change #bbbbbb to whatever color you fancy.

@schungx , just update that the way you mentioned is no longer valid, new way to figure this out is like this:

        "rust_analyzer.inlayHints.foreground": "#2E8B57",
        "rust_analyzer.inlayHints.background": "#3d3d3d48",
        // Overrides for specific kinds of inlay hints
        // "rust_analyzer.inlayHints.foreground.typeHints": "#fdb6fdf0",
        // // "rust_analyzer.inlayHints.foreground.paramHints": "#fdb6fdf0",
        // "rust_analyzer.inlayHints.background.chainingHints": "#6b0c0c81",

referring to : https://rust-analyzer.github.io/manual.html.

Somehow the new way is not working... The old way with workbench.colorCustomizations works... I suppose it'll be there for the up-coming version?

[Veykril]

Make sure your rust-analyzer is up to date, this change should be a bit older no already I believe.

[schungx]

It is the latest version already.

And it doesn't work, the setting is grayed out... see screenshot:

[Veykril]

Ah, it should say rust-analyzer.inlayHints.forground instead of rust_analyzer.inlayHints.forground(note the _ vs -).

[schungx]

Nope... changed it and still not working. Still grayed out.

I think the setting is still not correct...

That preference doesn't exist, it needs to be set in workbench.colorCustomizations, see https://rust-analyzer.github.io/manual.html#color-configurations. What do you mean by "the old way"?

[schungx]

What do you mean by "the old way"?

The old way is the workbencch.colorCustomizations way...

Hi, I am running the latest version and copy the setup jsonc code from manuall. It just does NOT work at all. What's the problem?

I have no ideas why this bug is opened and closed several times and nobody really mentioned what the cause is and how to fix it.

This works for me

{
  "workbench.colorTheme": "rustdoc dark",
  //   "editor.inlayHints.fontSize": 11,
  "editor.inlayHints.fontFamily": "Courier New",
  "workbench.colorCustomizations": {
    // Name of the theme you are currently using
    "[rustdoc dark]": {
      "editorInlayHint.foreground": "#888a",
      "editorInlayHint.background": "#0000"
      // Overrides for specific kinds of inlay hints
      // "editorInlayHint.typeForeground": "#fdb6fdf0",
      // "editorInlayHint.parameterForeground": "#fdb6fdf0",
    }
  }
}

    }
  }
}

hi @Plasmatium what theme and font do you use? it looks nice.

[Plasmatium]

Hi @yuhongyu879 please refer to the settings below. I remove the [rustdoc dark] block to make all themes affected

{
    "editor.fontFamily": "Cascadia Code PL",
    "editor.fontLigatures": true,
    "editor.fontSize": 14,
    "workbench.colorTheme": "Mariana Pro (Gray)",
    "editor.inlayHints.fontFamily": "Courier New",
    "workbench.colorCustomizations": {
        "editorInlayHint.foreground": "#888a",
        "editorInlayHint.background": "#0000",
    },
    "editor.tokenColorCustomizations": {
        "keywords": {
            "fontStyle": "bold"
        }
    },
}

@Plasmatium This worked for me. Thanks!

I tried to add @Plasmatium's editorInlayHint lines to a folder's settings.js. They had no effect, and when I moused over the settings I got an incredibly cryptic error, presented as a tooltip:

This setting cannot be applied in this workspace. It will be applied when you open the containing workspace folder directly.

In retrospect, I probably should have interpreted this as meaning to put the settings in the workspace file, as I eventually tried that and it worked.

// workspace file
{
        // ...
	"settings": {
		"workbench.colorCustomizations": {
			"editorInlayHint.foreground":"#bc0a",
			"editorInlayHint.background":"#0000"
		}
	}
}

This works in 2023
