Curl is a reflective object-oriented programming language for interactive web applications whose goal is to provide a smoother transition between formatting and programming.
It makes it possible to embed complex objects in simple documents without needing to switch between programming languages or development platforms.
The Curl implementation initially consisted of just an interpreter, but a compiler was added later.
Curl combines text markup (as in HTML), scripting (as in JavaScript), and heavy-duty computing (as in Java, C#, or C++) within one unified framework.
It is used in a range of internal enterprise, B2B, and B2C applications.
Curl programs may be compiled into Curl applets, that are viewed using the Curl RTE, a runtime environment with a plugin for web browsers.
Currently, it is supported on Microsoft Windows.
Linux, and macOS was dropped on March 25, 2019 (starting with version 8.0.10).
Curl supports “detached applets”, which is a web deployed applet which runs on the user’s desktop independent of a browser window much as in Silverlight 3 and Adobe AIR.
