Overall Assessment

This package is a self-contained template engine for PHP 8.2+. It supports everything from simple placeholders to advanced file-based templates with control structures, filters, functions, macros, and expression parsing. The engine was originally built independently and later adopted Twig-compatible syntax and design patterns during its evolution. No external dependencies required. The code is clean, well-structured, and extensible.

Overall Rating: (5/5)

Architecture

MemoryTemplate  (full engine: tokenizer, parser, renderer, expression evaluator,
                 33 built-in filters, addFilter/addFunction API)
    |-- FileTemplate  (reads files and passes to MemoryTemplate's engine)

MemoryTemplate contains the complete template engine. FileTemplate is a thin wrapper that reads template files from the filesystem and delegates to the parent class engine.
