browser-compat-data - This repository contains compatibility data for Web technologies as displayed on MDN

•    Javascript

This repository contains compatibility data for Web technologies. Browser compatibility data describes which platforms (where "platforms" are usually, but not always, web browsers) support particular Web APIs. This data can be used in documentation, to build compatibility tables listing browser support for APIs. For example: Browser support for WebExtension APIs.

PHPCompatibility - PHP Compatibility check for PHP_CodeSniffer

•    PHP

This is a set of sniffs for PHP CodeSniffer that checks for PHP cross-version compatibility. It will allow you to analyse your code for compatibility with higher and lower versions of PHP. The project aims to cover all PHP compatibility changes introduced since PHP 5.0 up to the latest PHP release. This is an ongoing process and coverage is not yet 100% (if, indeed, it ever could be). Progress is tracked on our Github issue tracker.

react-lifecycles-compat - Backwards compatibility polyfill for React class components

•    Javascript

React version 17 will deprecate several of the class component API lifecycles: componentWillMount, componentWillReceiveProps, and componentWillUpdate. (Read the Update on Async rendering blog post to learn more about why.) A couple of new lifecycles are also being added to better support async rendering mode. Typically, this type of change would require third party libraries to release a new major version in order to adhere to semver. However, the react-lifecycles-compat polyfill offers a way to use the new lifecycles with older versions of React as well (0.14.9+) so no breaking release is required. This enables shared libraries to support both older and newer versions of React simultaneously.

lua-compat-5.3 - Compatibility module providing Lua-5.3-style APIs for Lua 5.2 and 5.1

•    C

Lua-5.3-style APIs for Lua 5.2 and 5.1. This is a small module that aims to make it easier to write code in a Lua-5.3-style that is compatible with Lua 5.1, Lua 5.2, and Lua 5.3. This does not make Lua 5.2 (or even Lua 5.1) entirely compatible with Lua 5.3, but it brings the API closer to that of Lua 5.3.

shims - Seamless interop layer between cats and scalaz

•    Scala

Shims aims to provide a convenient, bidirectional, and transparent set of conversions between scalaz and cats, covering typeclasses (e.g. Monad) and data types (e.g. \/). By that I mean, with shims, anything that has a cats.Functor instance also has a scalaz.Functor instance, and vice versa. Additionally, every convertible scalaz datatype – such as scalaz.State – has an implicitly-added asCats function, while every convertible cats datatype – such as cats.free.Free – has an implicitly-added asScalaz function. Toss that at the top of any files which need to work with APIs written in terms of both frameworks, and everything should behave seamlessly. You can see some examples of this in the test suite, where we run the cats laws-based property tests on scalaz instances of various typeclasses.

shouldiprefix - A quick overview of what CSS features to prefix

Knowing what CSS features to prefix is hard. Things change (-OperaKit- anyone?) and documentation, even Preprocessor mixin libraries, are often out of date. This is simply(!) an attempt to have a handy list of CSS features and their prefixes, if any. While having a reference page such as this project provides is neat, parsing your CSS and automagically inserting the proper prefixes is awesome.

This module provides a monotonic() function which returns the value (in fractional seconds) of a clock which never goes backwards. It is compatible with Python 2 and Python 3. If no suitable implementation exists for the current platform, attempting to import this module (or to import from it) will cause a RuntimeError exception to be raised.
