Declaratively implementing a command. A method includes declaring an input gesture in a declarative programming language. Declaring an input gesture includes declaring one or more user performed actions. A command name is declared in a declarative programming language. A workflow is declared in a declarative programming language. Declaring a workflow includes declaring schedulable activities that are to be performed without specific specifications of the low level algorithms that are used to accomplish the activities. In an alternative example, workflows may be declared by declaring a wrapper to wrap imperative programming commands. The declared input gestures are bound with the declared workflow through the declared command name.
