    vue-observe-visibility

    vue-observe-visibility

    Detect when an element is becoming visible or hidden on the page

    vue-observe-visibility is a Vue plugin that detects when an element or component becomes visible or hidden in the browser viewport. It exposes the v-observe-visibility directive, which calls a user-defined function whenever visibility changes. The callback receives a Boolean visibility state and the corresponding IntersectionObserverEntry object. Developers can configure the observer root, root margin, and visibility threshold through standard Intersection Observer options. A once mode stops observation after the first visible event, making it useful for lazy loading and entrance animations. Throttling and leading-event controls reduce noisy updates during rapid scrolling. ...

    immutability-helper

    Mutate a copy of data without changing the original source

    React lets you use whatever style of data management you want, including mutation. However, if you can use immutable data in performance-critical parts of your application it's easy to implement a fast shouldComponentUpdate() method to significantly speed up your app. Dealing with immutable data in JavaScript is more difficult than in languages designed for it, like Clojure. However, we've provided a simple immutability helper, update(), that makes dealing with this type of data much easier,...

    React Values

    React Values

    A set of tiny React components for handling state with render props

    react-values is a lightweight React utility library that gives developers a set of tiny, composable components for managing state with a render-props API, so you don’t need to rewrite the same state logic over and over in your UI components. It exposes helpful state transforms like toggle, increment, filter, and native methods matching JavaScript value types (Array, Boolean, Number, Object, String, Map, Set, Date), which makes it easier to implement common behaviors like toggles, counters, and filtering right out of the box. Instead of forcing you into a specific global state system or hooks-only interface, it uses render props to keep components flexible and visible in the tree, enabling controlled and uncontrolled use cases alongside shared state patterns. ...

    Kotlin argparser

    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...

    JCLILIB

    A Java 7 library for parsing command lines.

    ...Features include recognizing arguments either by key ("-h"), by key and value ("-f some_file" or "-f=some_file"), or by position (e.g., second argument not attached to a key). Keys may optionally be repeated with multiple arguments. Values may be specified as String, Boolean, Integer, Long or Double. Unused arguments are returned in an array of strings. A static method is provided to parse arguments with glob-style wildcards (such as "*.bak") and return all matching files.

    Electronic Data Tags

    Electronic Data Tags value storage API For java.

    ...EDT is separated into two parts: EDT Basic (just called EDT) and EDTA (Advanced). EDT Basic stores only String values, while EDTA uses EDT Basic to store String, int, boolean, float, long, double, and byte values. To make accessing values easier, EDT and EDTA allow you to assign a name, like "FileLocation", to a value, instead of an integer, like in an array. The values are stored as ISO-8859-1 Strings.

    csg.js

    Constructive solid geometry on meshes using BSP trees in JavaScript

    csg.js is a JavaScript library implementing constructive solid geometry (CSG) operations on polygonal meshes using BSP trees. With CSG, you build complex 3D shapes by combining primitives using Boolean operations like union, subtract, and intersect. The library focuses on clarity and correctness: its implementation is intentionally concise and readable so developers can understand the algorithm, while still correctly handling tricky edge cases such as overlapping coplanar polygons. A WebGL-based demo shows how two solids can be combined interactively in the browser, making it a great educational tool for learning CSG concepts. ...

    Last Java Collection Library

    Java library to work with scalar arrays as usual Collections

    ...Java code working with collection interfaces such as List or Collection is inapplicable for arrays. Some libraries supply methods to work with object array. These methods are generic and built-in types int, boolean, long, short, byte, double, float suffer. The number of scalar type is small and finite. There are realization of Iterable, Iterator, Collection, and List interfaces for each scalar type. Also the library gives such useful methods as contains and indexOf for objects with Iterable interface only. Yeah. There is some stupidness because all implementations differ between each other only types and this code has 100% implicit coupling and duplications. ...
