Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Debugging template engines is challenging due to the difficulty in tracing the portions of the template and model that contribute to generated code, as existing debugging mechanisms are cumbersome and inefficient.

Innovation Solution

A system and method for tracing code generation in template engines, which includes a template engine that generates an execution log mapping code segments to instructions, allowing for the identification of specific template and model components used in code generation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If template engines are used to increase abstraction and separate technical/creative aspects, then productivity is improved, but debugging difficulty increases

Engineering Contradiction:

Improvesoftware development productivityVSAvoiddebugging difficulty

Core Design Contradiction:

ProductivityVSDifficulty of detecting and measuring

Solution Approach 1:

The system performs preliminary actions by generating an execution log during the code generation process that records the mapping between generated code and template instructions. This log is created in advance before debugging is needed, enabling traceability without requiring retroactive analysis or cumbersome debugger stepping through the generation process.

Inventive Principle:

Principle #10Preliminary action

2Ease of operation

If code generation is automated through template engines, then ease of operation is improved, but traceability of generated code deteriorates

Engineering Contradiction:

Improvecode generation easeVSAvoidtraceability information

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system implements feedback by generating an execution log that provides traceability information about which template instructions produced which generated code segments. This feedback loop maintains the connection between high-level template operations and low-level generated code, enabling developers to trace back from generated code to source template instructions without manual intervention.

Inventive Principle:

Principle #23Feedback

3Reliability

If existing debugging mechanisms are used for template engines, then debugging capability is maintained, but ease of operation deteriorates due to cumbersome debugger stepping

Engineering Contradiction:

Improvedebugging capabilityVSAvoiddebugging ease

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The execution log serves as an intermediary data structure that bridges the gap between template instructions and generated code. Instead of directly debugging the complex template engine execution process through cumbersome stepping, developers can use the execution log to trace and identify problematic code segments by examining the recorded mappings between template instructions and generated code.

Inventive Principle:

Principle #24Intermediary (Mediator)
