Kotlin Date Range

GitHub Workflow Status Maven Central

This is a tiny implementation of rangeTo operator for Date and LocalDate that makes the syntax for loop iteration and control flow statements safe and natural to read.

Installation

Add the kotlin-date-range to your dependencies section:

dependencies {
  implementation 'me.moallemi.tools:kotlin-date-range:1.0.0'
}

How to use

From Java SE 8 onwards, users are asked to migrate to java.time (JSR-310). For Android users, java.time is added in API level 26+. Projects needing to support lower API levels can use java.util.Date.

with java.time.LocalDate

Using rangeTo operator:

import me.moallemi.tools.daterange.localdate.rangeTo

val startDate = LocalDate.of(2020, 3, 22)
val endDate = LocalDate.of(2020, 4, 1)
for (date in startDate..endDate) {
    println(date)
}

Usage with step function:

import me.moallemi.tools.daterange.localdate.rangeTo

val startDate = LocalDate.of(2020, 3, 22)
val endDate = LocalDate.of(2020, 4, 1)
for (date in startDate..endDate step 2) {
    println(date)
}

Using with in operator:

import me.moallemi.tools.daterange.localdate.rangeTo

val startDate = LocalDate.of(2020, 1, 1)
val endDate = LocalDate.of(2020, 1, 5)

val result: Boolean = LocalDate.of(2020, 1, 2) in (startDate..endDate)

with java.util.Date

Using rangeTo operator:

import me.moallemi.tools.daterange.date.rangeTo

val calendar = Calendar.getInstance(Locale.getDefault())
calendar.set(2020, 0, 1)
val startDate = calendar.time
calendar.set(2020, 0, 5)
val endDate = calendar.time
for (date in startDate..endDate) {
    println(date)
}

Usage with step function:

import me.moallemi.tools.daterange.date.rangeTo

for (date in startDate..endDate step 2) {
    println(date)
}
