google-java-format
Reformats Java source code to comply with Google Java Style
google-java-format is a program that reformats Java source code to comply with Google Java Style. The formatter can act on whole files, on limited lines, on specific offsets, passing through to standard-out (default) or altered in-place. There is no configurability as to the formatter's algorithm for formatting. This is a deliberate design decision to unify our code formatting on a single format. The formatter can be used in software that generates java to output more legible java code. Just include the library in your maven/gradle/etc. configuration. A google-java-format IntelliJ plugin is available from the plugin repository. To install it, go to your IDE's settings and select the Plugins category. Click the Marketplace tab, search for the google-java-format plugin, and click the Install button. -

Aztec
A reusable native Android rich text editor component
Aztec (which extends EditText) is a rich-text editor component for writing HTML documents in Android. You can check the minimum Android version supported by looking at the minSdkVersion configuration within build.gradle. There is an optional list type you can enable in the editor. In addition to ordered and unordered lists you can use task list. A task list is an unordered list that shows and saves checkboxes instead of bullets. By default, Aztec allows nested blocks. In certain cases, this doesn't have to be the preferred behavior. There is an option to disable nested blocks. When switched, this editor will always add media and horizontal rules after the currently selected block, not in the middle of it. Aztec now supports placeholders to draw views that are not natively supported by the EditText and Spannable API. The functionality creates a span in the visual editor and draws an Android view over it. -

Mozilla JPEG Encoder Project
Improved JPEG encoder
MozJPEG improves JPEG compression efficiency achieving higher visual quality and smaller file sizes at the same time. It is compatible with the JPEG standard, and the vast majority of the world's deployed JPEG decoders. MozJPEG is compatible with the libjpeg API and ABI. It is intended to be a drop-in replacement for libjpeg. MozJPEG is a strict superset of libjpeg-turbo's functionality. All MozJPEG's improvements can be disabled at run time, and in that case it behaves exactly like libjpeg-turbo. MozJPEG is meant to be used as a library in graphics programs and image processing tools. We include a demo cjpeg command-line tool, but it's not intended for serious use. We encourage authors of graphics programs to use libjpeg's C API and link with MozJPEG library instead. Progressive encoding with "jpegrescan" optimization. It can be applied to any JPEG file (with jpegtran) to losslessly reduce file size. -

Kryo
Java binary serialization and cloning, fast, efficient, automatic
Kryo is a fast and efficient binary object graph serialization framework for Java. The goals of the project are high speed, low size, and an easy-to-use API. The project is useful any time objects need to be persisted, whether to a file, database or over the network. Kryo can also perform automatic deep and shallow copying/cloning. This is direct copying from object to object, not object to bytes to object. Kryo has three sets of methods for reading and writing objects. If the concrete class of the object is not known and the object could be null. Besides methods to read and write objects, the Kryo class provides a way to register serializers, reads and writes class identifiers efficiently, handles null objects for serializers that can't accept nulls, and handles reading and writing object references (if enabled). This allows serializers to focus on their serialization tasks. -

ServiceStack
Simple, fast, versatile and full-featured services framework
One framework to power them all. Write your HTTP APIs once and take advantage of end-to-end typed integrations for all popular web, mobile and desktop platforms. ServiceStack's primary goal is to enhance the value of System APIs which serve as the blueprint that most features centered around. By using simple & pure dependency-free DTO models decoupled from any implementation we're free to continue layering on features which now sees ServiceStack APIs as the most versatile in the world where the same high-performance APIs can be consumed from HTTP in any combination of Route, QueryString, FormData or a myriad of data formats, via popular resilient MQ Servers whilst simultaneously supporting legacy integrations like SOAP or adopting new technologies like gRPC without sacrificing any native HTTP integrations. To maximize the value of APIs we're focused beyond the API boundary by making it as simple as possible for API Consumers to call your APIs. -

iCheck
Highly customizable checkboxes and radio buttons
Highly customizable checkboxes and radio buttons for jQuery and Zepto. jQuery and Zepto JavaScript libraries support from single file. iCheck works with checkboxes and radio buttons like a constructor. It wraps each input with a div, which may be customized by you or using one of the available skins. You may also place inside that div some HTML code or text using insert option. By default, iCheck doesn't provide any CSS styles for wrapper divs (if you don't use skins). HTML5 allows specifying indeterminate ("partially" checked) state for checkboxes. iCheck supports this for both checkboxes and radio buttons. You can make an input indeterminate through HTML using additional attributes (supported by iCheck). Both do the same job, but indeterminate="true" may not work in some browsers (like IE7). iCheck provides plenty callbacks, which may be used to handle changes. -

Awesome Blazor
Resources for Blazor, a .NET web framework using C#/Razor
Blazor lets you build interactive web UIs using C# instead of JavaScript. Blazor apps are composed of reusable web UI components implemented using C#, HTML, and CSS. Both client and server code is written in C#, allowing you to share code and libraries. Blazor is a feature of ASP.NET, the popular web development framework that extends the .NET developer platform with tools and libraries for building web apps. Blazor can run your client-side C# code directly in the browser, using WebAssembly. Because it's real .NET running on WebAssembly, you can re-use code and libraries from server-side parts of your application. Alternatively, Blazor can run your client logic on the server. Client UI events are sent back to the server using SignalR, a real-time messaging framework. Once execution completes, the required UI changes are sent to the client and merged into the DOM. -

Gradle Kotlin DSL converter
Convert from Groovy to Kotlin DSL for Gradle, focused on Android
Welcome! After a lot of pain trying to migrate from Gradle's Groovy to Kotlin DSL on Android Studio, I developed this tool to solve most migration issues and reduce the amount of work you need in order to make things ready. Please see this tool as a helper, a first resource like Android Studio's Java converter to Kotlin: it won't make a perfect conversion, but it helps a lot in reducing the time you would spend on repetitive tasks. Sometimes you just want to copy and paste. Just copy whatever you want, run the script, then paste on your IDE. The script was made to convert build.gradle in build.gradle.kts, but it can also help in the migration if you paste something that is not in Kotlin DSL format and you want it converted. -

Sizzle
A sizzlin' hot selector engine
A pure-JavaScript CSS selector engine designed to be easily dropped in to a host library. Browser support may differ between standalone Sizzle and libraries that include Sizzle. Please report issues on Sizzle's issue tracker, rather than the trackers for disparate libraries. In order to build Sizzle, you should have Node.js/npm latest and git 1.7 or later (earlier versions might work OK, but are not tested). For Windows you have to download and install git and Node.js. Mac OS users should install Homebrew. Once Homebrew is installed, run brew install git to install git, and brew install node to install Node.js. Linux/BSD users should use their appropriate package managers to install git and Node.js, or build from source if you swing that way. Workarounds for Internet Explorer 6 are still in the code but the browser is no longer actively tested. Sizzle supports virtually all CSS 3 Selectors, including escaped selectors (.foo\+bar), Unicode selectors, and more.
