Jinja
Explanation of Jinja Syntax:

{{ ... }}: This is used to output the value of a variable or the result of an expression.

{% if ... %} {% elif ... %} {% else %} {% endif %}: This is a conditional statement, similar to if-elif-else in Python.

{% for ... in ... %} {% endfor %}: This is a loop, used to iterate over a list or dictionary.

| (pipe): This is used to apply a filter to a variable. For example:

{{ activity.other_details | tojson }} converts the other_details variable to JSON format.

{{ similar_activities | join(', ') }} joins the elements of the similar_activities list into a string separated by commas.

How to Use the Jinja Template:

Data: You'll need to pass data to the template in a dictionary-like structure. The keys in the dictionary will correspond to the variables used in the template (e.g., activity_name, opening_hours, distance, general_knowledge_answer, etc.).

Rendering: Use a Jinja environment to render the template with the data. Here's a simple Python example using the jinja2 library:

from jinja2 import Environment, FileSystemLoader

# Set up Jinja environment
env = Environment(loader=FileSystemLoader('.'))  # Assuming the template is in the current directory
template = env.get_template('chat_template.jinja')

# Example data
data = {
    "activity_type": "listed",
    "information_available": True,
    "activity": {
        "name": "Musée de l'Ephèbe",
        "opening_hours": "10:00 AM - 6:00 PM",
        "address": "Mas de la Clape, 34300 Cap d'Agde",
        "distance": "3 km",
        "other_details": {"ticket_price": "8 euros", "audio_guide": "available"},
        "is_open_now": True
    }
}

# Render the template with the data
output = template.render(data)
print(output)

Will have a look. We're aware of a couple instances where it seems a newly added dependency - jinja2cpp - seems to crash with particular syntax. Thanks for the bug report.
