Can this skill help with cursor-based navigation logic?

Yes, it includes patterns for calculating offsets, finding word boundaries, and navigating between lines and columns using Document navigation methods.

What is the primary difference between a Buffer and a Document in prompt_toolkit?

A Buffer is a mutable object that manages the active editing state, history, and cursor, whereas a Document is an immutable representation of the text and cursor position at a specific point in time.

How do I react to text changes in real-time?

You can use the on_text_changed or on_cursor_position_changed event handlers provided by the Buffer class to trigger custom logic whenever the state changes.

How do I implement undo and redo functionality using this skill?

The skill provides guidance on using the Buffer's built-in .undo() and .redo() methods, which interact with the buffer's internal history management.

Herramientas para Desarrolladores

Manages complex text manipulation and state handling for Python prompt_toolkit applications.

Acerca de

This skill equips Claude with specialized knowledge for implementing and managing Buffer and Document objects within the prompt_toolkit library. It provides patterns for sophisticated text editing features including cursor positioning, selection logic, undo/redo history, and real-time event handling. Whether you are building an interactive CLI, a terminal-based text editor, or a complex data entry form, this skill ensures best practices for managing mutable text buffers and immutable document snapshots within a Terminal User Interface (TUI).
