An opinionated string DSL for creating UTC time ranges.

Get a lilrange.Range from a string.

range, err := lilrange.Parse("0000-0400")

The returned range's End time is guaranteed to be in the future. The Start time could be in the past, or the future.

To determine if your current system time is inside the range, pass a time.Time to the Within method.

// get a lilrange.Range
r, _ := lilrange.Parse("0130-0230")

// get the current time with Go's time package
now := time.Now()

// Are we within the Range?
if r.Within(now) {
    fmt.Println("We are inside the range")
}

A test program can be compiled from the lilrange sub directory, or use go get -u if $GOPATH/bin is on your PATH.

go get -u github.com/dontlaugh/lilrange/lilrange

Give it a lilrange string to test the behavior.

lilrange 0415-0445
