Type Editor / @type-editor/input

@type-editor/input

This is a refactored version of the input handling logic from prosemirror-view.

This module provides input handling functionality for the Type Editor. It handles all user interactions including keyboard input, mouse events, clipboard operations, drag-and-drop, touch events, and composition (IME) input.

Input State

The InputState class tracks the current input state of the editor, including keyboard modifier keys, mouse state, composition events, and selection state. It registers and manages all event handlers for the editor.

Clipboard Operations

Functions for serializing and parsing content to and from the clipboard. This enables copy, cut, and paste operations while preserving document structure.

serializeForClipboard

Serializes a slice of document content for placing on the clipboard. Produces a DOM fragment, plain-text representation, and the (possibly normalized) slice.

import { serializeForClipboard } from "@type-editor/input";

const { dom, text, slice } = serializeForClipboard(view, slice);

doPaste

Processes pasted content by parsing it and inserting it into the editor. Delegates to the handlePaste prop if available, otherwise inserts the content directly.

import { doPaste } from "@type-editor/input";

doPaste(view, text, html, preferPlain, event);

Drag and Drop

The Dragging class represents an active drag operation, storing information about what content is being dragged and whether it's a move or copy operation.

import { Dragging } from "@type-editor/input";

const dragging = new Dragging(slice, isMove, nodeSelection);

Composition Handling

Utilities for managing IME (Input Method Editor) composition state, which is crucial for proper handling of complex scripts like CJK (Chinese, Japanese, Korean) input.

clearComposition

Clears the current composition state and marks affected DOM nodes as dirty so they will be re-rendered correctly.

import { clearComposition } from "@type-editor/input";

clearComposition(view);

Event Handlers

The module includes handlers for various DOM events:

• Keyboard: keydown, keypress, keyup, compositionstart, compositionupdate, compositionend
• Mouse: mousedown, contextmenu
• Touch: touchstart, touchmove
• Clipboard: copy, cut, paste
• Drag/Drop: dragstart, dragend, dragover, dragenter, drop
• Focus: focus, blur
• Input: beforeinput
