Prompt Template Loader System

A Prompt Template Loader System is a template loading system that retrieves, caches, and renders prompt templates from packaged resources using Python import mechanisms and template engines.

• AKA: Prompt Loader, Template Loader, Prompt Resource Loader, Template Loading System, Prompt Retrieval System, Template Resource Manager, Prompt Import System.
• Context:
  • It can typically utilize importlib.resources API for package resource access in Python 3.9+ environments.
  • It can typically implement Template Caching Strategys for frequently used prompts to improve performance characteristics.
  • It can often support Multiple Loading Mechanisms including file-based approaches, package-based approaches, and registry-based approaches.
  • It can often provide Template Rendering Services using Jinja2 engine, string.Template module, or custom template engines.
  • It can handle Resource Path Resolution across zip distributions, wheel packages, and installed packages.
  • It can implement Lazy Loading Patterns to minimize memory footprint and startup time.
  • It can validate Template Parameters against defined schemas before rendering operation.
  • It can support Template Inheritance Mechanisms for prompt composition and reusability patterns.
  • It can manage Template Dependencys through import resolution and reference tracking.
  • It can range from being a Simple Prompt Template Loader System to being an Advanced Prompt Template Loader System, depending on its feature complexity.
  • It can range from being a Synchronous Prompt Template Loader System to being an Asynchronous Prompt Template Loader System, depending on its execution model.
  • It can range from being a Single-Source Prompt Template Loader System to being a Multi-Source Prompt Template Loader System, depending on its data sources.
  • It can range from being a Static Prompt Template Loader System to being a Dynamic Prompt Template Loader System, depending on its update capability.
  • ...
• Examples:
  • Loading Implementation Patterns, such as:
    • PackageLoader Implementation using Jinja2 Environment for template discovery.
    • importlib.resources Loader for Python 3.9+ compatibility.
    • pkg_resources Loader for legacy Python versions.
    • FileSystemLoader Implementation for development environments.
  • Caching Strategy Implementations, such as:
    • In-Memory Template Cache, such as:
      • LRU Cache Implementation with size limits.
      • TTL-Based Cache with expiration policy.
      • Precompiled Template Cache for performance optimization.
    • Persistent Template Cache, such as:
      • Redis-Based Cache for distributed systems.
      • SQLite Cache for local applications.
      • File System Cache for offline capability.
  • Rendering Features, such as:
    • Parameterized Template Rendering with variable substitution.
    • Conditional Template Rendering with control structures.
    • Template Inheritance Support for prompt composition.
    • Filter Pipeline Processing for output transformation.
  • Error Handling Patterns, such as:
    • Graceful Fallback Mechanism for missing templates.
    • Template Validation System for syntax checking.
    • Debug Mode Support for development troubleshooting.
  • ...
• Counter-Examples:
  • Direct String Concatenation, which lacks template management and parameter validation.
  • Manual File Reading, which lacks package compatibility and resource management.
  • Hardcoded Prompt String, which lacks loading mechanism and flexibility.
  • Runtime String Generation, which lacks template structure and caching benefits.
