Undoable Timed Reactive Programming Language Core
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional programming languages lack efficient mechanisms for fully undoable and timed reactive instructions, particularly in multi-modal user interfaces, making it difficult to recover from erroneous actions and maintain program state information across multimedia interactions.
Innovation Solution
A programming language is developed with a fully undoable core language portion and a conventional language portion, where the core language supports fully undoable, timed reactive instructions, enabling complete undoability and integration with conventional language mechanisms for multimedia and multi-modal input, using XML trees, XPATH expressions, and event systems for concurrency and state management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional programming languages are used, then device complexity is reduced, but the ability to recover from erroneous actions and maintain program state information is insufficient
Solution Approach 1:
The programming language is segmented into two distinct portions: a core language portion with fully undoable, timed reactive instructions for reliable state recovery, and a conventional language portion for standard programming operations. This segmentation allows the patent to achieve full recovery capability in the core language while maintaining compatibility with conventional programming practices through the conventional language portion.
Solution Approach 2:
The programming language achieves universality by integrating both the core language with undoable reactive instructions and the conventional language portion into a single unified language system. This multi-functionality enables the language to provide both enhanced recovery capabilities for critical operations and standard programming functionality, resolving the contradiction between reliability improvement and complexity increase.
2Reliability
If fully undoable timed reactive instructions are implemented, then recovery capability is improved, but ease of operation is reduced due to the need to track previous system states
Solution Approach 1:
The core language portion implements self-service by automatically tracking and maintaining previous system states through timed reactive instructions. The system autonomously records state information and enables recovery without requiring the programmer to explicitly manage state tracking, thereby achieving full undoability while maintaining ease of operation through automatic state management.
3Reliability
If command encapsulation with centralized state tracking is used, then recovery capability is improved, but device complexity increases
Solution Approach 1:
The patent merges the command encapsulation approach with the core language's timed reactive instructions into a unified system. The centralized state tracking is integrated directly into the core language execution model, combining command encapsulation benefits with automatic state management to achieve improved recovery capability without proportionally increasing system complexity.
