range-v3 - Experimental range library for C++11/14/17

•    C++

---

Range library for C++11/14/17. This code is the basis of a formal proposal to add range support to the C++ standard library. Why does C++ need another range library? Simply put, the existing solutions haven't kept up with the rapid evolution of C++. Range v3 is a library for the future C++. Not only does it work well with today's C++ -- move semantics, lambdas, automatically deduced types and all -- it also anticipates tomorrow's C++ with Concepts.

tbox - 📦 A glib-like multi-platform c library

•    C

---

TBOX is a glib-like cross-platform C library that is simple to use yet powerful in nature. The project focuses on making C development easier and provides many modules (.e.g stream, coroutine, regex, container, algorithm ...), so that any developer can quickly pick it up and enjoy the productivity boost when developing in C language.

IxJS - The Interactive Extensions for JavaScript

•    TypeScript

---

The Interactive Extensions for JavaScript (IxJS) brings the Array#extras combinators to iterables, generators, async iterables and async generators. With the introduction of the Symbol.iterator and generators in ES2015, and subsequent introduction of Symbol.asyncIterator and async generators, it became obvious we need an abstraction over these data structures for composition, querying and more.IxJS unifies both synchronous and asynchronous pull-based collections, just as RxJS unified the world of push-based collections. RxJS is great for event-based workflows where the data can be pushed at the rate of the producer, however, IxJS is great at I/O operations where you as the consumer can pull the data when you are ready.

scandir - Better directory iterator and faster os.walk(), now in the Python 3.5 stdlib

•    Python

---

scandir() is a directory iteration function like os.listdir(), except that instead of returning a list of bare filenames, it yields DirEntry objects that include file type and stat information along with the name. Using scandir() increases the speed of os.walk() by 2-20 times (depending on the platform and file system) by avoiding unnecessary calls to os.stat() in most cases. PEP 471, which is the PEP that proposes including scandir in the Python standard library, was accepted in July 2014 by Victor Stinner, the BDFL-delegate for the PEP.

chillout - Reduce CPU usage in JavaScript

•    Javascript

---

Reduce JavaScript CPU usage by asynchronous iteration. Provides asynchronous iteration functions that have a Promise based interface and it can execute with low CPU usage. Each iteration adds delay if the processing is heavy to maintain the CPU stability. Iterate without delay if processing is fast. Therefore, it will realize friendly processing for your machine. It can execute JavaScript without "Warning: Unresponsive Script" alert in the browser.

tstl - TypeScript-STL (Standard Template Library, migrated from C++)

•    TypeScript

---

Implementation of STL (Standard Template Library) in TypeScript. TSTL is an open-source project providing features of STL, migrated from C++ to TypeScript. You can enjoy the STL's own specific containers, algorithms and functors in the JavaScript. If TypeScript, you also can take advantage of type restrictions and generic programming with the TypeScript.

p-waterfall - Run promise-returning & async functions in series, each passing its result to the next

•    Javascript

---

Returns a Promise that is fulfilled when all promises returned from calling the functions in tasks are fulfilled, or rejects if any of the promises reject. The fulfilled value is the value returned from the last task.Functions are expected to return a value. If a Promise is returned, it's awaited before continuing with the next task.

iterator-stream - Turn a leveldown iterator into a readable stream

•    Javascript

---

Create a readable stream from iterator. options are passed down to the require('readable-stream').Readable constructor, with objectMode forced to true.Set options.keys or options.values to false to only get values / keys. Otherwise receive { key, value } objects.

iterum - Handling iterables like lazy arrays.

•    Javascript

---

iterum library provides a class for handling iterable transformations inspired in Array methods and lodash/fp functions. This library also supplies combinatorial functions like permutations, combinations, variations, product, power and powerSet that has a high computational cost but this library is able to support taking advantage of lazy evaluation.Then, obj can be processed as an ordered list of values. However, unlike built-in iterables (Array, Set, Map, String, etc), obj is a lazy iterable. It means that, thanks to generators, obj does not store the computed values in memory and its values are computed just when are required. These are the essential features for implementing lazy evaluation.

chimes - `Array.prototype` iteration methods for any iterator.

•    Javascript

---

Array.prototype iteration methods for any iterator.It's hard to justify using the new iterable data structures in ES6 as they're severely lacking in expressive power when compared to Arrays e.g. no map/filter/reduce etc. This library's goal is to add the expressive power of Arrays to anything iterable, including generators.

http-agent - A simple agent for performing a sequence of http requests in node.js

•    Javascript

---

Since http-agent is based on top of request, it can take a set of JSON objects for request to use. If you're looking for more documentation about what parameters are relevant to http-agent, see request which http-agent is built on top of.Each time an instance of http-agent raises the 'next' event the agent is passed back as a parameter. That allows us to change the control flow of pages each time a page is visited. The agent is also passed back to other important events such as 'stop' and 'back'.
