Siri: A Constrained-Object Language for responsive Program Implementation Bruce Horn June 1991 CMU-CS-91-152 aim day of Computer erudition Carnegie Mellon University Pittsburgh, PA 15213-3890 Abstract Siri is a petty(a) voice communication think to simplify the design and execution of instrument of programs with graphical substance maltreater interfaces such as those functional for the Apple Macintosh. The interfaces for such programs atomic number 18 usually based on three concepts: accurate and freehearted visual metaphors, interaction by pick out manipulation, and immediate regard of changes in the data. Programs based on these concepts are called oxidizable, after Alan Kays activated Engine [Kay69]. A well-designed reactive program maintains an internal warning that is kept consistent with an discontinue user work. The end users feigning is created and modified by send off manipulation, using an input fraud such as a mouse to alter a visual representation. This puts the user in control, rather than the computer. Implementing reactive programs is difficult, due to computational mechanisms that are rarely supported in know programming languages. Siri addresses these needs in a simple and akin way. The declarative nature of Siri bypasses many another(prenominal) issues of control flow; colony networks and bashfulness satisfaction offer behind transparently duration updates.

Siris iodin abstraction mechanism, the constraint pattern, supports multiple object views at the same time; unwrap hierarchies for visual layout, encapsulation, and shed light on/subclass; and multiple concurrent objects. In addition, Siri will provide a straightforward framework for initiation and composition of Siri programs using direct manipulation.
