Scriptan

Scriptan is a term used to describe a family of lightweight, embeddable scripting languages and runtimes designed to provide automation capabilities within host software. It is not a single standardized language, but a collection of projects and design patterns that share a focus on simplicity, safety, and easy integration.

Design goals for Scriptan implementations typically include a small runtime footprint, fast startup, and a clean interface for binding to host applications. Many Scriptan runtimes prioritize safe execution, sandboxing, and a straightforward foreign function interface to expose host APIs to scripts. The languages in this family are generally interpreted or bytecode-based, with an emphasis on predictable performance and low memory overhead to suit embedded or extension scenarios.

Syntax and semantics commonly feature dynamic typing, first-class functions, and a modular organization for code reuse. Scriptan implementations often provide a standard library with essential data structures, I/O, string processing, and utilities for interacting with the host environment. Some variants offer optional typing through annotations or gradual typing systems to improve reliability in larger projects, while retaining flexibility for small scripts.

Embedding and use cases are central to Scriptan. It is used to automate tasks within applications such as games, editors, data processing pipelines, and workflow tools. Scriptan languages are chosen for their ease of embedding, cross-platform compatibility, and the ability to extend or customize software without rebuilding core components.

History and variants arise from open-source communities rather than a single governing body. Over time, multiple implementations have emerged with varying performance profiles, libraries, and bindings. Scriptan remains a concept describing a pragmatic approach to scripting that emphasizes embeddability, safety, and developer productivity.
