A Clojure library for working with time-varying signals.
- Pure Clojure, builds upon IRef/IDeref.
- Treats standard Clojure Atoms, Refs, Agents as time-varying, mutable signals. Users should use these in the normal way.
- Adds reactive events and signals that uses the watches feature of Clojure's IRef's. Reactive signals can also be watched by other reactive signals and events.
- Graph of signals and events can be dynamically modified. Reactors can be enabled and disabled.
- Builds upon the apply!*! operator, which applies a function with dynamic args. Used as the basis of lifting functions to work on signals.
- Signals can be lazy or strict: lazy signals do not update their values until they are dereferenced, while strict signals are updated immediately when dependents notify of a change.
- Seeks to make code that works with mutable values "highly visible" as well as isolated to be as small an area of the total codebase as possible.
- Work with projections of data (CursorSignals) as a view upon a larger signal. Allows reads from/writes to CursorSignals that operate with the original signal.
Please see the documentation for further information about the library.
Please see the demo file for example usage.
