A multiplexor for aligned time.Time tickers in Go

go get



This package is a wrapper around a single time.Ticker in the Go language, which provides a way for lots of listeners to subscribe to a single set of ticks. If a subscriber is busy and can't receive a tick, it will be discarded; the implementation is non-blocking. Additionally, ticks can be aligned to a specific boundary easily, which eliminates annoying code from your programs.

We use this functionality at VividCortex to help coordinate worker goroutines, driving them by passing them ticker channels. This makes the workers more testable, by avoiding nondeterministic use of time.Tick() inside them.


Please read the generated package documentation.

Getting Started

Install multitick in the usual way:

go get

And import it as usual:

import (

To use multitick, create a ticker with the desired interval and offset. For example, to create a once-per-second ticker that will send at 750 milliseconds past the clock tick,

tick := multitick.NewTicker(time.Second, time.Millisecond*750)

If you want the ticker to start immediately instead of waiting, you can pass a negative number as the second parameter.

Now subscribe to ticks. Here's an example of starting worker routines with ticker channels:

go someFunc(tick.Subscribe())
go otherFunc(tick.Subscribe())
