[Documentation](https://grrr-amsterdam.github.io/garp-functional/) Developed with ❤️ by [GRRR](https://grrr.nl) -------------------------------------------- [](#developed-with-️-by-grrr) - GRRR is a [B Corp](https://grrr.nl/en/b-corp/) - GRRR has a [tech blog](https://grrr.tech/) - GRRR is [hiring](https://grrr.nl/en/jobs/) - [@GRRRTech](https://twitter.com/grrrtech) tweets Philosophy ---------- [](#philosophy) `Garp\Functional` is a practical functional library that strives to embrace functional paradigms. - Functions are pure, referentially transparent, without side-effects. - Data immutability is favored over mutating existing properties of given parameters. - In general, functions are curried. Almost all of the functions in the library can be called partially applied, to a point where this makes sense. - Function parameters are ordered to promote currying. Data is usually the last thing to go in, making every function a fine candidate to pass to native `array_map`, `array_filter` and the like, without having to create a closure around the call. - Higher-order functions are provided to fill the gaps. Functions like `compose`, `partial`, `partial_right` or `not` are legos for you to use in your own implementation. - Nothing is type-hinted too strictly. I don't care if you pass a string or an array to `prop`, as long as it allows accessing members thru bracket syntax `[]`, I'll allow it. Nothing irks me more about PHP than not being able to toss a `Traversable`object into the native `array_map`. - Typeclasses are added, broadening the applicability of the functions. Next to primitives, they will now work with your objects as well, so long as they implement the right interface. Usage ----- [](#usage) Installation: ``` composer require grrr-amsterdam/garp-functional ``` That'll do, all functions are available to you. [Read the docs for a complete reference](https://grrr-amsterdam.github.io/garp-functional/) Thanks ------ [](#thanks) This library is inspired by beautiful languages like [Haskell](https://www.haskell.org/) and [Clojure](https://clojure.org/), as well as the awesome [RamdaJS](https://ramdajs.com/) library. ### Health Score 51 — FairBetter than 95% of packages Maintenance55 Moderate activity, may be stable Popularity41 Moderate usage in the ecosystem Community24 Small or concentrated contributor base Maturity72 Established project with proven stability Bus Factor1 Top contributor holds 74.7% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
