How to show customize the icon before completion icon?

[durianwaffle]

I want to use customized icon for completion items.
Currently I can only use CompletionItemKind.

Here is the list of completion icons by VSCode

Hey @durianwaffle,

can you explain (with words preferably) what you want to do and what you're missing? The Langium API just exposes the LSP completion kinds directly. You can use the NodeKindProvider or CompletionProvider to adjust the kind returned by each individual completion result.

These icons are associated with CompletionItemKind, which is a fixed enum (you cannot add your own kind). There was a discussion about adding support for custom icons in microsoft/vscode#113313 (PR), but seems like Microsoft is not planning on merging it. It seems that the only way is to customize the existing icons, according to microsoft/vscode#223340
