GrooveTemplates

GrooveTemplates is a templating engine designed for the Groove software ecosystem. It provides a simple, readable syntax for generating dynamic text and code from structured data. Templates are authored as text files and can be used to render HTML, configuration files, emails, or other textual outputs. GrooveTemplates emphasizes portability, ease of embedding in applications, and predictable rendering behavior.

Core features include variable interpolation, conditional rendering, iterative loops, and support for reusable blocks and layout inheritance. The engine also offers built-in or extendable filters for data transformation, escaping to prevent injection attacks, and internationalization helpers. Developers can register custom functions or tags to extend the template language, enabling domain-specific templates without modifying the core.

Under the hood, GrooveTemplates consists of a parser that converts templates into an intermediate representation and a runtime evaluator that renders output using a data model provided at render time. The data model is typically provided as maps or dictionaries, often derived from JSON or YAML sources. Templates may include partials or includes to compose complex documents from smaller pieces, and can leverage a sandboxed execution mode to improve security.

GrooveTemplates integrates with common application stacks through a small API: loading templates from files or strings, compiling them for efficiency, and rendering with a given context. It supports caching of compiled templates and can be used in server-side or client-side environments depending on the host platform. The project aims for a stable, cross-platform template language with a predictable feature set and an active ecosystem of community contributors.
