• Inheritance: Placeholdr supports template inheritance, allowing developers to create a base template with common elements and extend it with more specific templates.
• Includes: Placeholdr allows for including other template files within a template using the {% include "path/to/template" %} syntax, promoting modularity and reusability.
• Control Structures: Placeholdr offers a variety of control structures like {% if condition %}, {% endif %}, {% for item in iterable %}, and {% endfor %} to enable dynamic content generation.
• Filters: Placeholdr supports filters for manipulating variables within the template (e.g., {{ variable | filter_name }}), providing a powerful way to format and process data.
• Custom Tags and Macros: Placeholdr allows developers to create custom tags and macros using {% call macro_name() %} and {% endcall %}, enhancing the flexibility and functionality of the engine.
• Automatic HTML Escaping: Placeholdr automatically escapes HTML special characters to prevent security vulnerabilities such as XSS attacks.
• Customizable: Placeholdr is highly extensible, allowing developers to add their own filters, control structures, tags, and macros as needed, tailoring the engine to fit their specific requirements.
