I recently wrote two utility functions for core.async, and I'm wondering if there could be some improvemets, or if I'm reinventing the wheel and there's something else out there that would accomplish the same thing.
Source code is available here: https://github.com/JvJ/specs/blob/master/src/specs/core.cljc#L469 Here are the functions: - timeout-at: Like timeout, but instead of specifying a wait period, you specify a point in time when you want the channel to close. (Uses clj-time DateTime objects). - beacon: Send out a signal on a channel at regular intervals of m milliseconds from the present time. Instead of waiting m milliseconds every time through the loop, future points in time are calculated at exact intervals of m from when the beacon is started. It uses timeout-at to send the signal as closely as possible to the requested time points. The default output values is true. If something happens that makes one of the time points get skipped, a different value is output. The default value to indicate a skipped time point is false. Beacon can also act like core/iterate if you want. You can pass a function to update both the successful output values and the skipped-time output values, and the return value of the last output is used as the input to the function to create the next output. So, are these functions useful, or am I missing some totally obvious other way to do it. By the way, the motivation here is to signal an async game update loop at a constant framerate, while at the same time keeping track of skipped frames.
