Hacker Scripts
Based on a true story
Hacker Scripts is a cheeky collection of small automation scripts and language ports collected under the tagline “Based on a true story.” The repository gathers playful utilities (originally shell and Ruby scripts) that automate short, real-world tasks — for example, sending a quick “late at work” text when SSH sessions are active, firing off an automated “I’m sick / working from home” email on certain mornings, or even talking to a networked coffee machine to start brewing at precisely the right moment. The README explains the origin story and highlights several canonical scripts and provides usage notes such as required environment variables and cron examples for scheduling. Contributors have provided implementations and ports in many languages and folders (shell, Ruby, Python, Node, Perl, PowerShell, Go, Java, etc.), and the project explicitly welcomes pull requests that add additional language implementations. -

Kotlin JDSL
Kotlin library that makes it easy to build and execute queries
Kotlin JDSL is a Kotlin library that makes it easy to build a query without a generated metamodel. There are many libraries that use an annotation processing tool (APT) to do the job. However, with the APT, you have to recompile whenever the name or type of field in an entity or a table class is changed. Kotlin JDSL provides a domain-specific language (DSL) based on KClass and KProperty to help you easily build queries without such inconveniences from the APT. Kotlin JDSL does not provide an executor or a wrapper class as it is designed to help you build and execute queries with the library you are using. -

GraphQL Kotlin
Libraries for running GraphQL in Kotlin
graphql-java is one of the most popular JVM-based GraphQL implementations. GraphQL Kotlin is built on top of grahpql-java as it can be easily extended with additional functionality and this implementation has been used and tested by many users. The most common way to create the schema in graphql-java is to first manually write the SDL file. Then write the runtime code that matches this schema to build the GraphQLSchema object. This means that there are two sources of truth for your schema and changes in either have to be reflected in both locations. As your schema scales to hundreds of types and many different resolvers, it can get more difficult to track what code needs to be changed if you want to add a new field, deprecate or delete an existing one, or fix a bug in the resolver code. graphql-kotlin-schema-generator aims to simplify this process by using Kotlin reflection to generate the schema for you. All you need to do is write your schema code in a Kotlin class. -

LeakCanary
A memory leak detection library for Android
LeakCanary is a reliable memory leak detection library for Android. It effectively detects leaks and narrows down the cause of each leak through its in-depth knowledge of the internals of the Android Framework. This helps developers avoid and dramatically reduce OutOfMemoryError (OOM) crashes. A memory leak is a programming error that can cause an OutOfMemoryError crash. It’s often caused by bugs related to the lifecycle of objects, and can occur fairly often in Android applications. LeakCanary helps to find and fix those leaks during development so you never have to experience another OOM crash. -

Lyricist
Missing I18N/L10N (internationalization/localization) multiplatform
Jetpack Compose greatly improved the way we build UIs on Android, but not how we interact with strings. stringResource() works well, but doesn't benefit from the idiomatic Kotlin like Compose. Lyricist tries to make working with strings as powerful as building UIs with Compose, i.e., working with parameterized string is now typesafe, use of when expression to work with plurals with more flexibility, and even load/update the strings dynamically via an API. -
