unittools Build Status License Maven Scaladex Codacy codecov

Some basic unit conversion operation. It Assumes that default units are milliseconds for durations, and bytes for data size.

In your build.sbt, add this :

libraryDependencies += "fr.janalyse" %% "unittools" % version


Examples coming from the test cases :

  test("duration rewritten") {
    "1".toDuration.toDurationDesc should equal("1ms")
    "7d".toDuration.toDurationDesc should equal("1w")
    "60m".toDuration.toDurationDesc should equal("1h")
    "3600s".toDuration.toDurationDesc should equal("1h")
    "3600000ms".toDuration.toDurationDesc should equal("1h")

  test("size basics") {
    0.toSizeDesc should equal("0b")
    1.toSizeDesc should equal("1b")
    "1mb".toSize should equal(pow(1024L,2))
    "10mb25kb".toSize should equal(10*pow(1024L,2)+25*1024L)

  test("classes parameter usage") {
    import fr.janalyse.unittools._
    case class ExampleClass(howlong:DurationHelper, amount:SizeHelper)
    val example = ExampleClass(howlong="5h30m", amount="10mb")
    val howlong:Long = example.howlong
    val amount:Long  = example.amount

  test("basics") {
    (5 m).value should equal (60L*1000*5)
    (3 h).value should equal (3600L*1000*3)
    (1.m + 1.s).value should equal (61L*1000)
    (1.h + 10.m + 10.s).value should equal (3600L*1000+600*1000+10*1000)
