Templatingsprog

Templatingsprog is a template engine and templating language designed to separate content from presentation across software projects. It provides a declarative syntax for embedding data and light logic into text templates, along with a runtime capable of loading data models and rendering output in various formats. Implementations exist for multiple programming languages, and the core design emphasizes portability, composability, and security.

Origin and evolution: The concept of templatingsprog emerged in the early 2010s as a general approach to templating, with several independent implementations contributing to its maturation. Over time, practitioners emphasized practices such as strict escaping, streaming rendering, and support for reusable components known as templates or partials.

Design and features: The language offers placeholders for data fields, control structures like conditionals and loops, and filters or transformers to format values. It supports macros or partial templates for reuse, layout templates for inheritance, and blocks for extensibility. Runtimes often include sandboxing to limit side effects, automatic escaping to prevent injection, and caching of compiled templates for performance. Some implementations provide tooling for template discovery, error reporting, and integration with build or deployment workflows.

Usage: Common use cases include generating configuration files, code scaffolding, emails, and static site content. Templatingsprog is typically integrated into web frameworks, content pipelines, or automation scripts where templates are provided with a data model.

Example: Template: "Hello {{name}}, you have {{count}} new messages." Data: { name: "Alex", count: 3 }. Rendered: "Hello Alex, you have 3 new messages." See also template engines, data templating, and document generation.
