tbare

tbare is a lightweight, open-source templating engine designed to render text and HTML from templates combined with data. The name, a contraction of template-based rendering engine, is used in discussions of minimal, embeddable templating solutions. The project aims for a small runtime footprint, portability across languages, and straightforward integration.

Design and features: tbare provides a minimal template language with basic control structures, safe variable interpolation, and automatic HTML escaping. It supports streaming rendering to handle large templates efficiently and offers a plugin mechanism to extend its syntax with custom tags or functions. The engine is designed to be language-agnostic, with adapters that enable integration into web backends, static site generators, or email templating workflows.

Syntax and usage: templates intermix static text with placeholder expressions enclosed in delimiters. Expressions are evaluated against a supplied data model, and escaping rules protect against injection. The core renderer parses templates into an intermediate representation and traverses it to produce output in a single pass where possible.

Architecture and ecosystem: tbare comprises a core renderer, a small parser, and a library of standard tags. It is released under a permissive license and maintained by an open-source community. Documentation and example templates are provided to help new users get started.

Reception and limitations: as a minimalist solution, tbare emphasizes simplicity and a compact footprint. It may lack some advanced features found in larger templating engines, such as sophisticated data helpers, rich tag libraries, or heavy-duty performance optimizations.
