HumanReadable

A small set of data formatting utilities for Kotlin Multiplatform (KMP).

This library only supports kotlinx-datetime.

Installation

The library is published to Maven Central.

dependencies {
    implementation("nl.jacobras:human-readable:1.4.0")
}

Features

🕰️ Relative time

HumanReadable.timeAgo(now - 134.minutes) // "2 hours ago"
HumanReadable.timeAgo(now + 8.minutes) // "in 8 minutes"

⏱️ Duration

HumanReadable.duration(5.seconds) // "5 seconds"
HumanReadable.duration(7.days) // "1 week"
HumanReadable.duration(544.hours) // "3 weeks"

Note: The formatter switches to a bigger unit (minute, hour, day, ...) as soon as it can. See Precision.

📂 File size

File size formatting uses base 1024.

HumanReadable.fileSize(333) // "333 B"
HumanReadable.fileSize(2_048, decimals = 1) // "2.0 kB"
HumanReadable.fileSize(21_947_282_882, decimals = 2) // "20.44 GB"

Date/time precision

The formatter switches to a bigger unit (minute, hour, day, ...) as soon as it can. For example:

59.seconds is "59 seconds" but 60.seconds becomes "1 minute"
6.days is "6 days" but 7.days becomes "1 week"
29.days is "29 days" but 30.days becomes "1 month"

There's also some rounding involved:

8.days and 10.days are "1 week", but 11.days already becomes "2 weeks"

This behaviour may become configurable in future releases.

Localisation

The library uses the small Libres library for its string resources. It detects the current locale by default, but it's changeable on runtime. See Libres: Changing Localization.

You don't need to manually import Libres, as Gradle already pulls it in along with HumanReadable.

HumanReadable.timeAgo(instant) // "3 days ago"

LibresSettings.languageCode = "nl"
HumanReadable.timeAgo(instant) // "3 dagen geleden"

LibresSettings.languageCode = "fr"
HumanReadable.timeAgo(instant) // "il y a 3 jours"

Adding a language

Missing a language? Feel free to open an issue about it. Or, add it yourself:

Fork the code and navigate to src/commonMain/libres/strings/
Add a file named time_units_[LANGUAGE CODE].xml (see Unicode: CLDR chart for the code & plural categories).
If the language deviates from English data units (like French does), also add data_units_[LANGUAGE CODE].xml.
