jitterbug's Introduction

jitterbug

Tickers with random jitter

Godoc Reference Go Report Card

Installation

go get -u github.com/lthibault/jitterbug

Usage

Jitterbug is used by instantiating a jitterbug.Ticker with an interval and a jitterbug.Jitter. The former specifies a baseline interval for the ticker, to which a jitter is added by the latter.

package main

import (
    "log"

    "github.com/lthibault/jitterbug"
)

func main() {
    t := jitterbug.New(
        time.Millisecond * 300,
        &jitterbug.Norm{ Stdev: time.Millisecond * 100 },
    )

    // jitterbug.Ticker behaves like time.Ticker
    for tick := <- range t.C {
        log.Println(tick)
    }
}

Jitterbug is compatible with the univariate distributions from GoNum. For example:

t := jitterbug.New(
    time.Millisecond * 300,
    &jitterbug.Univariate{
        Sampler: &distruv.Gamma{
            // Tip: cast time.Duration as float64 when using gonum's distruv
            Alpha: float64(time.Millisecond * 100),
            Beta:  float64(time.Millisecond * 200),
        }
    },
)

Seriously, even if you just used it in your weekend project, I'd like to hear about it :)
