Kord
Idiomatic Kotlin Wrapper for The Discord API
Kord is still in an experimental stage, as such we can't guarantee API stability between releases. While we'd love for you to try out our library, we don't recommend you use this in production just yet. Kord was created as an answer to the frustrations of writing Discord bots with other JVM libraries, which either use thread-blocking code or verbose and scope-restrictive reactive systems. We believe an API written from the ground up in Kotlin with coroutines can give you the best of both worlds: The conciseness of imperative code with the concurrency of reactive code. Aside from coroutines, we also wanted to give the user full access to lower-level APIs. Sometimes you have to do some unconventional things, and we want to allow you to do those in a safe and supported way. -

KotCity
KotCity, an open source city simulator
This is pre-alpha software with super obvious bugs, rough edges, etc. In the spirit of "release early and release often", I am posting the code. This project is far from done but I prefer to get the code out there to be used by whomever. KotCity is a city simulator written in Kotlin inspired by the statistical city simulators of old. This game aims to achieve a mark somewhere between SimCity (1989) and SC2000. Hopefully, this mark will be hit and we can set our sights higher. The game will be fully supported on Windows, macOS, and Linux. -

Kotlin Dataframe
Structured data processing in Kotlin
Data frame is an abstraction for working with structured data. Essentially it’s a 2-dimensional table with labeled columns of potentially different types. You can think of it like a spreadsheet or SQL table, or a dictionary of series objects. The handiness of this abstraction is not in the table itself but in a set of operations defined on it. The Kotlin Dataframe library is an idiomatic Kotlin DSL defining such operations. The process of working with data frame is often called data wrangling which is the process of transforming and mapping data from one "raw" data form into another format that is more appropriate for analytics and visualization. The goal of data wrangling is to assure quality and useful data. -

Kotlin argparser
Easy to use and concise yet powerful and robust command line argument
This is a library for parsing command-line arguments. It can parse both options and positional arguments. It aims to be easy to use and concise yet powerful and robust. An instance of MyArgs will represent the set of parsed arguments. Each option and positional argument is declared as a property that delegates through a delegate factory method on an instance of ArgParser. The name of an option is inferred from the name of the property it is bound to. The options above are named -v, --name and --count, respectively. There are also two positional arguments. -

KotlinPoet
A Kotlin API for generating .kt source files
KotlinPoet is a Kotlin and Java API for generating .kt source files. Source file generation can be useful when doing things such as annotation processing or interacting with metadata files (e.g., database schemas, protocol formats). By generating code, you eliminate the need to write boilerplate while also keeping a single source of truth for the metadata. -

Kotlingrad
Shape-Safe Symbolic Differentiation with Algebraic Data Types
Kotlin∇ is a type-safe automatic differentiation framework written in Kotlin. It allows users to express differentiable programs with higher-dimensional data structures and operators. We attempt to restrict syntactically valid constructions to those which are algebraically valid and can be checked at compile-time. By enforcing these constraints in the type system, it eliminates certain classes of runtime errors that may occur during the execution of a differentiable program. Due to type-inference, most type declarations may be safely omitted by the end-user. Kotlin∇ strives to be expressive, safe, and notationally similar to mathematics. -

Kotshi
An annotation processor that generates Moshi adapters
An annotation processor that generates Moshi adapters from Kotlin classes. There is a reflective adapter for Kotlin but that requires the Kotlin reflection library which adds a lot of methods and increases the binary size which in a constrained environment such as Android is something is not preferable. This is where Kotshi comes in, it generates fast and optimized adapters for your Kotlin data classes, just as if you'd written them by hand yourself. It will automatically regenerate the adapters when you modify your class. It's made to work with minimal setup, through there are limitations. Most of the limitations will be addressed as the support for Kotlin annotation processors improves. -

Ktlint Gradle
A ktlint gradle plugin
Provides a convenient wrapper plugin over the ktlint project. This plugin creates convenient tasks in your Gradle project that run ktlint checks or do code auto format. The plugin can be applied to any project, but only activates if that project has the kotlin plugin applied. The assumption being that you would not want to lint code you weren't compiling. This plugin was written using the new API available for the Gradle script Kotlin builds. This API is available in new versions of Gradle. To test KtLint snapshots add following configuration into project build script. This plugin just adds special tasks that can generate IntelliJ IDEA codestyle rules using ktlint. The version of ktlint used by default may change between patch versions of this plugin. If you don't want to inherit these changes then make sure you lock your version. -

Landscapist
Pluggable, highly optimized Jetpack Compose image loading library
Landscapist is a highly optimized, pluggable Jetpack Compose image loading solution that fetches and displays network images with Glide, Coil, and Fresco. This library supports tracing image loading states, composing custom implementations, and some valuable animations, such as crossfades, blur transformation, and circular reveals. You can also configure and attach image-loading behaviors easily and fast with image plugins. Landscapist is built with a lot of consideration to improve the performance of image loadings in Jetpack Compose. Most composable functions of Landscapist are Restartable and Skippable, which indicates fairly improved recomposition performance according to the Compose compiler metrics. Also, the library performance was improved with Baseline Profiles and it supports many pluggable features, such as ImageOptions, listening image state changes, custom composables, preview on Android Studio, ImageComponent and ImagePlugin, placeholder, and animations. -
