Underscore.php is a utility-belt library for PHP that provides support for common higher-order functions, such as, each, map, reduce, and filter. Underscore.php is a port of the popular Underscore.js library, which also includes matching unit tests.

Similar to #1149866: Add Backbone.js and Underscore.js to core, if Core standardized this library, modules could reuse the same common functions when programming operations which return or operate on data, collections, and functions.

Some potential use cases

  • Creating manageable, complex entities and fields which implement ComplexDataInterface
  • Composing data calculations and text processing features from separate, modular features
  • Implementing routing similar to Laravel, another Symfony based framework

A lot of this looks like it exists already in PHP, just as a function with an array_ prefix.

I'm not clear on the use case. We're not doing Laravel-style routing. At first glance it works on arrays, not collection objects, which limits its usefulness to the things that PHP already has natively. I guess I just don't get it...

Just looking at some of the methods, probably i didnt do enough research but map, reduce, etc exist just fine already as native php functions.

We already have a http://drupal.org/node/1794140 Typed Data API. How would this simplify / complicate / overlap / relate altogether ?

Version: 8.0.x-dev » 8.1.x-dev

Title: Add Underscore.php to Core » Add Underscore.php to Core or another fluent array manipulation wrapper library
Version: 8.1.x-dev » 8.2.x-dev

Following the DrupalCon New Orleans session "Rethinking Loops" I think we should reopen the issue as the arguments presented during the session are very convincing. Nesting calls to php's built-in array_* functions makes code harder to read and harder to manipulate, and the Drupal project would benefit from a collection manipulation library.

Other alternatives (mentioned during the presentation):
- \Haystack\HArray

Feel free to suggest a better one.
