FlexScript

FlexScript is a scripting language intended for automating tasks and extending functionality within applications built on the Flex platform. It provides access to host APIs, supports event-driven patterns, and is designed to be embedded and executed inside a running application or runtime. Developers write scripts to customize behavior, define data transformations, and respond to user actions.

FlexScript offers a familiar, C-style syntax and supports objects, functions, modules, and control flow constructs. It is designed to be portable across host environments and to interoperate with the platform’s UI components and data models. The runtime includes error handling, memory management, and debugging facilities to aid development.

Programs in FlexScript run on a dedicated runtime embedded in the host application, allowing scripts to be loaded dynamically or compiled ahead of time. The language emphasizes rapid iteration, sandboxing options, and integration with the platform’s event loop and messaging system.

FlexScript originated with the Flex platform and has undergone several iterations as the platform evolved. While it remains in use in some legacy and specialized deployments, many modern Flex-based projects favor general-purpose scripting languages or platform-agnostic extension mechanisms. Documentation typically covers API references, language features, and best practices for extensibility.
