Smart Paste

The SmartPastePlugin detects structured content (JSON, XML, Java, TypeScript) in pasted clipboard text and automatically inserts it as a formatted code block with the detected language.

Usage

import { SmartPastePlugin } from '@notectl/core/plugins/smart-paste';

new SmartPastePlugin()
// or with custom detectors:
new SmartPastePlugin({ detectors: [myDetector] })

Dependencies

This plugin requires the CodeBlockPlugin to be loaded.

How It Works

When text is pasted, the plugin runs registered content detectors against the plain text. Each detector returns a confidence score (0—1) and a language identifier. The detector with the highest confidence above the threshold wins, and the content is inserted as a code block with the detected language.

If the cursor is already inside a code block, smart paste is skipped.

Built-in Detectors

Detector	Language	Description
JSON	json	Detects valid JSON objects and arrays
XML	xml	Detects XML documents and fragments
Java	java	Detects Java source code (class/interface/enum/record declarations, package/import statements, method signatures)
TypeScript	typescript	Detects TypeScript / modern JavaScript (ES module imports/exports, type aliases, interfaces, decorators, arrow functions, optional chaining). Includes negative signals to avoid misdetecting Java code.

Detectors are registered automatically by the CodeBlockPlugin via the language registry. When multiple detectors match the same input, the one with the highest confidence wins; on ties the earliest-registered detector wins (registration order: Java → JSON → TypeScript → XML).

Configuration

interface SmartPasteConfig {
  /** Additional content detectors to register. */
  readonly detectors?: readonly ContentDetector[];
  /** Custom locale strings. */
  readonly locale?: SmartPasteLocale;
}

Option	Type	Description
detectors	readonly ContentDetector[]	Additional content detectors to register
locale	SmartPasteLocale	Custom locale strings

Custom Detectors

You can add custom detectors via configuration or at runtime via the service.

Via Configuration

const myDetector: ContentDetector = {
  id: 'yaml',
  detect(text: string): DetectionResult | null {
    if (looksLikeYaml(text)) {
      return { language: 'yaml', formattedText: text, confidence: 0.8 };
    }
    return null;
  }
};

new SmartPastePlugin({ detectors: [myDetector] })

Via Service

import { SMART_PASTE_SERVICE_KEY } from '@notectl/core/plugins/smart-paste';

// Inside a plugin's init method:
const smartPaste = context.getService(SMART_PASTE_SERVICE_KEY);
smartPaste?.registerDetector(myDetector);

Accessibility

When structured content is detected and formatted, the plugin announces the detection to screen readers.
