Usage examples

import { Plugin, EditorSuggest, SuggestModal, TFile, SectionCache } from "obsidian";
import { registerQuickPreview } from "obsidian-quick-preview";

class MyCustomEditorSuggest extends EditorSuggest<{ file: TFile }> { ... }

class MyCustomSuggestModal extends SuggestModal<{ path: string, cache: SectionCache }> { ... }

export default MyPlugin extends Plugin {
    excludedFiles: string[];

    onload() {
        registerQuickPreview(this.app, this, MyCustomEditorSuggest, (item) => {
            // - `linktext` can be any string representing a proper internal link,
            //   e.g. "note", "note.md", "folder/note", "folder/note.md", "note#heading", "note#^block-id" etc
            // - `sourcePath` is used to resolve relative links. In many cases, you can just pass an empty string.
            return { linktext: item.file.path, sourcePath: "" };
        });
        // or
        registerQuickPreview(this.app, this, MyCustomSuggestModal, (item) => {
            if (this.excludedFiles.contains(item.path)) {
                // Return `null` when you don't want to show a quick preview for the item.
                return null;
            }
            // Add a `line` parameter to focus on a specific line.
            return { linktext: item.path, sourcePath: "", line: item.cache.position.start.line };
        });
    }
