Splitties

Splitties is a collection of small Kotlin multiplatform libraries (with Android as first target).

These libraries are intended to reduce the amount of code you have to write, freeing code reading and writing time, so you can focus more on what you want to build for your users (even if you're the only one), or have more time to have fun.

This project is named "Splitties" because it is split in small modules, distributed as independent libraries, so you can add only the ones you need to your project/module, helping reduce the size of the final binary that users devices will need to download and keep in the limited storage (BTW, everything is limited).

Some Android targeting modules have a content similar to what Anko offers. See a short comparison of Splitties with Anko here.

Each module has been designed to have a small footprint and be as efficient as possible.

All the multiplatform splits

Currently, only JVM (including Android) and JS are supported, but future Kotlin/Native support is considered (you can subscribe to this issue to get updated on that).

  • Bit Flags: hasFlag, withFlag and minusFlag extensions on Long, Int, Short, Byte, and their unsigned counterparts.
  • Collections: forEach for Lists without Iterator allocation.

Gradle instructions

Make sure you have jcenter() in the repositories defined in your project's (root) build.gradle file (default for new Android Studio projects).

To make is easier to take advantage of the contents of Splitties for your Android projects, there are grouping artifacts that include most splits.

Android base

These 2 packs don't include AppCompat and are suitable for WearOS apps.

Includes the following modules:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-base:3.0.0-alpha06")

There's also a version with Views DSL. It additionally includes the following modules:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-base-with-views-dsl:3.0.0-alpha06")

Android AppCompat

These 2 packs include the Android base pack, and the following modules:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-appcompat:3.0.0-alpha06")

There's also a version with Views DSL. It additionally includes the Views DSL version of the Android base pack and the following module:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-appcompat-with-views-dsl:3.0.0-alpha06")

Android Material Components

These 2 packs include the Android AppCompat pack, and the following modules:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-material-components:3.0.0-alpha06")

There's also a version with Views DSL. It additionally includes the Views DSL version of the Android AppCompat pack and the following modules:

Gradle dependency:

implementation("com.louiscad.splitties:splitties-fun-pack-android-material-components-with-views-dsl:3.0.0-alpha06")

All the artifacts (47)

Add the version of the library to not repeat yourself if you use multiple artifacts, and make sure their versions are in sync by adding an ext property into your root project build.gradle file:

allProjects {
    ext {
        splitties_version = "3.0.0-alpha06"
    }
}

Dev versions

Let's say you need a new feature or a fix that did not make it to a release yet:

You can grab it in the latest dev version by adding the corresponding repository and changing the library version to the dev version you need in your root project build.gradle file:

allProjects {
    repositories {
        google()
        jcenter() // Add dev versions repo below
        maven { url 'https://dl.bintray.com/louiscad/splitties-dev' }
    }
    ext {
        splitties_version = '3.0.0-dev-008'
    }
}

Other build systems

For maven and alternative build-systems, check the Bintray page.

New versions notifications

Releases are announced on GitHub, you can subscribe byclicking on "Watch", then "Releases only".

Improve this library

If you want this library to have a new feature or an improvement in a new or in an existing module, please, open an issue or vote/comment a similar one first, so it can be discussed.

Documentation contributions are also welcome. For typos or other small improvements, feel free to submit a PR (pull request) directly. For more significant doc contributions, please, open an issue first so it can be discussed.

If you find a bug, please open an issue with all the important details. If you know a simple fix that is not API breaking and that does not have side-effects that need to be considered, you may also directly submit a PR.

You can also join the discussion on Kotlin's Slack in the #splitties channel (you can get an invitation here).

What is a split

A "split" is a module of the Splitties library that you can add as a dependency. It only includes the required transitive dependencies. This allows you to only add what you need in your app or library module, so the final apk is as small as possible and doesn't include stuff not used by your app.

Let's say you're build a Wear OS app using the Views DSL. Wear OS apps don't need AppCompat. Including it would be a waste of bandwidth and storage. The Views DSL core module relies on the Android SDK but not on AppCompat, so you don't bloat your wrist app with AppCompat by using Views DSL. However, if you are building a phone, tablet or computer Android app, there's a Views DSL AppCompat split with a few extensions for you to use.

Credits

Special thanks to Jovche Mitrejchevski for helping in taking decisions for this project.

Thanks to JetBrains and the contributors for Anko, which was a great source of inspiration, especially for Views DSL, and of course thanks for the excellent Kotlin programming language that makes this project possible.

Thanks to Doug Stevenson for his articles "Kotlin & Android: A Brass Tacks Experiment". It is fair to say that Views DSL has its root in this experiment.
