Jinja2 Prompt Template

A Jinja2 Prompt Template is a prompt template that uses Jinja2 template syntax for dynamic variable substitution and control flow logic in AI prompt generation.

• AKA: J2 Prompt Template, Jinja Template for Prompts, Jinja2 Template, Jinja-based Prompt.
• Context:
  • It can typically support Variable Substitution with filter functions and custom formatters.
  • It can typically enable Template Inheritance for prompt reusability and template composition.
  • It can often implement Control Structures including conditional blocks and iteration loops.
  • It can often provide Macro Definitions for reusable prompt components and template functions.
  • It can often integrate with Environment Configuration for custom filters and global variables.
  • It can often support Template Loading through file system loaders and package loaders.
  • It can often facilitate Error Handling with template debugging and error messages.
  • It can range from being a Simple Jinja2 Prompt Template to being a Complex Jinja2 Prompt Template, depending on its control flow complexity.
  • It can range from being a Static Jinja2 Prompt Template to being a Dynamic Jinja2 Prompt Template, depending on its runtime generation capability.
  • It can range from being a Single-File Jinja2 Prompt Template to being a Multi-File Jinja2 Prompt Template, depending on its template organization.
  • It can range from being a Standalone Jinja2 Prompt Template to being a Inherited Jinja2 Prompt Template, depending on its template hierarchy.
  • ...
• Examples:
  • Basic Jinja2 Prompt Template Implementations, such as:
    • LangChain PromptTemplate using Jinja2 syntax for variable substitution.
    • Guidance Template with handlebars-like syntax for structured generation.
  • Advanced Jinja2 Prompt Template Patterns, such as:
    • Few-Shot Prompt Template with `{% for example in examples %}` loops.
    • Chain-of-Thought Template using conditional logic for reasoning steps.
  • Domain-Specific Jinja2 Prompt Templates, such as:
    • Code Generation Prompt Template for programming tasks.
    • Data Analysis Prompt Template for analytical querys.
  • ...
• Counter-Examples:
  • Static Text Prompt, which lacks dynamic substitution and variable replacement.
  • F-String Prompt, which uses Python f-strings instead of Jinja2 syntax.
  • Mustache Template, which uses different template syntax and limited control flow.
