Inspired heavily by similar projects like libphutil. Currently used in personal and work projects. Designed to make working wth PHP a little bit nicer and predictable. Requires HHVM 3.6 or PHP 5.6 Goal ---- [](#goal) - Provide a consistent API for common operations. - Gather the most useful bits and snippets under one library. - Strong emphasis on strict type checking (e.g. `float !== integer`). - Functional programming ideas and concepts are welcome (I'm new to this). Core pieces ----------- [](#core-pieces) While Nucleus has a bunch of random crap in it, there are some useful classes worth mentioning: - **Spec**: A multi-purpose constraint checking framework that can be easily extended. - **Validator**: Built upon Spec, the Validator component provides an interface for generating UX-friendly messages for a SpecResult. - **Impersonator**: A constructor dependency automocker. Useful for testing classes that have many external dependencies and projects that heavily use container dependency injection. - **View**: An set of classes and utilities for generating clean and safe HTML/Text. It sort of looks like XHP without the XML or de-sugarized React.js code. - **Std, Arr, and others**: We all know the PHP standard library is a mess. There are many failed attempts to fix this out there. This is another one of those attempts. I've created a few classes with a bunch of static aliases that attempt to improve upon it. Yes, there is a performance penalty (validation + at least one more function call), but it makes many operations more predictable and safer.

Bug fixes and small improvements are welcome. Big ideas will be reviewed and discussed. Code Standard: PSR-2 with some additions. See for more details.
