Jinja2 Prompt Template System

A Jinja2 Prompt Template System is a prompt template system that uses Jinja2 syntax for creating dynamic prompt templates with variable substitution, control structures, and template inheritance.

• AKA: Jinja2 Templates, Jinja Prompt Templates, Jinja2 Framework, Python Jinja Templates, Jinja Template Engine.
• Context:
  • It can typically support Variable Substitution using double brace syntax like Template:Variable for dynamic content.
  • It can typically implement Control Structures including for loops, if statements, and macro definitions.
  • It can often enable Template Inheritance through block definitions, parent templates, and child templates.
  • It can often provide Filter Functions for text transformation, data formatting, and output processing.
  • It can facilitate Template Composition through include statements, import directives, and template reuse.
  • It can support Custom Filters and custom tests through Python functions and extension mechanisms.
  • It can handle Whitespace Control through trim blocks, lstrip blocks, and manual control.
  • It can implement Auto-Escaping for security protection, XSS prevention, and safe rendering.
  • It can provide Debug Mode with error messages, line numbers, and traceback information.
  • It can range from being a Simple Jinja2 Prompt Template System to being a Complex Jinja2 Prompt Template System, depending on its feature utilization.
  • It can range from being a Standalone Jinja2 Prompt Template System to being an Integrated Jinja2 Prompt Template System, depending on its deployment context.
  • It can range from being a File-Based Jinja2 Prompt Template System to being a String-Based Jinja2 Prompt Template System, depending on its template source.
  • It can range from being a Synchronous Jinja2 Prompt Template System to being an Asynchronous Jinja2 Prompt Template System, depending on its rendering mode.

• Examples:
  • Template Features, such as:
    • Variable Expressions, such as:
      • Simple Variable like Template:User name.
      • Attribute Access like Template:User.profile.name.
      • List Index like {{ items[0] }}.
    • Control Flows, such as:
      • Conditional Block with {% if condition %}.
      • Loop Structure with {% for item in items %}.
      • Macro Definition with {% macro name() %}.
  • Filter Applications, such as:
    • Text Filters like Template:Text, Template:Text.
    • List Filters like Template:Items, Template:Items.
    • Date Filters like Template:Date.
  • Framework Integrations, such as:
    • Flask Integration for web applications.
    • LangChain Integration for LLM applications.
    • Ansible Integration for configuration management.
  • Template Patterns, such as:
    • Base Template Pattern with common layout.
    • Partial Template Pattern for reusable components.
    • Dynamic Include Pattern for conditional content.
  • ...
• Counter-Examples:
  • String Formatting, which uses Python f-strings without template structure.
  • Simple Substitution, which uses string.Template without control flow.
  • Regex Replacement, which uses pattern matching without template logic.
  • Hardcoded String, which lacks dynamic capability and template features.
