## Pages

- [Introduction](https://www.xraph.com/docs/dtl.md): DTL is a small, embeddable expression and function language for Go, readable by analysts, safe to evaluate on untrusted input, and designed for a host that supplies its own vocabulary.
- [Language specification](https://www.xraph.com/docs/dtl/specification.md): The syntax, semantics and type system of DTL, from function declarations through pattern matching, pipes, collection operations and error handling.
- [Standard library](https://www.xraph.com/docs/dtl/standard-library.md): The five pure namespaces that ship preloaded with DTL — maths, text, datetime, statistics and collections — each written in DTL itself.
