**MetaTemplating **

An advanced Python templating engine for dynamic text generation, supporting placeholders, expressions, and scripting logic.

🌟 Features

✅ Dynamic Placeholder Substitution – Supports expressions, variables, and default values
✅ Inline Computation – Evaluates expressions like <time.strftime("%m/%d/%Y")>
✅ Variable Storage – Cache results for reuse (<UUID() |-> stored_uuid>)
✅ Pre-processing Scripts – Run initialization logic before parsing templates
✅ Batch Processing – Generate structured text efficiently

🛠 Installation

pip install metatemplating

📌 Usage Example

Basic Placeholder Substitution

from MetaTemplating import Template

template_str = "Today's date: <time.strftime('%m/%d/%Y')>"
tpl = Template(template_str)
tpl.analyze_template()
print(tpl.fill_template())  # Outputs: Today's date: 05/10/2025

Variable Storage and Retrieval

template_str = "Generated UUID: <UUID() |-> stored_uuid>\nThe second time: <$stored_uuid>"
tpl = Template(template_str)
tpl.analyze_template()
print(tpl.fill_template())

Using a Pre-script for Initialization

script_template = """
|>ScriptBeforeTemplate
store("author", "John Doe")
|>EndScript
Written by <$author>
"""
tpl = Template(script_template)
tpl.analyze_template()
print(tpl.fill_template())  # Outputs: Written by John Doe

🎨 Advanced Template Processing

MetaTemplating supports custom templates, batch processing, and integration with external data sources.

data = {"score": 95}
template_str = "Score result on [time.asctime(time.localtime())]:\n<$name | DefaultName>: <$score>"
tpl = Template(template_str)
tpl.analyze_template()
print(tpl.fill_template(data))  # Outputs: Hello Alice, you scored 95 in the exam.
