Scape Templates

A lightweight, standalone PHP template engine designed for simplicity, security, and performance. Scape focuses on being an Output Engine first, marrying pre-processed data with design while enforcing a "logic-light" philosophy.

Features

Dot Notation & Bracket Access: Effortlessly access nested objects and arrays.
Inheritance & Blocks: Define base layouts and override sections in child templates.
Partials & Includes: Reuse template snippets with controlled data scoping.
Filter Pipeline: Transform data using built-in or custom filters (e.g., {{ var | lower | ucfirst }}).
- Built-in filters: lower, upper, ucfirst, currency, float, date, truncate, default, json, url_encode, join, first, last, word_count, keys.
- Filters can be used in variable interpolations, foreach loops, and include tags.
Secure by Default: Automatic contextual HTML escaping for all variables.
AST Caching: High performance via Abstract Syntax Tree caching with automatic dev-mode invalidation.
Host Integration (IoC): Easy integration with frameworks through the reserved host namespace.
Logic-Light: Encourages separation of concerns by supporting only necessary logic like foreach.
