Ducter allows such neat calls to your functions ``` ducter( "Hello World", htmlentities(...), str_split(...), [array_map(...), fn(string $part) => strtoupper($part)], ) ``` Call functions like an array: ``` _p("Hello World") [htmlentities(...)] [str_split(...)] [[array_map(...), strtoupper(...)]]() ``` How about Closure() on Closure ``` _p("Hello World") (htmlentities(...)) (strtoupper(...)) (str_split(...)) (array_map(...), strtoupper(...))() ``` Cleaner with underscore `_` ``` _p("Hello World") ->_(htmlentities(...)) ->_(str_split(...)) ->_(array_map(...), strtoupper(...))); ``` Shortcut to `pipe()` is `p()` ``` _p("Hello World") ->p(htmlentities(...)) ->p(str_split(...)) ->p(array_map(...), strtoupper(...))() ``` PHP 7.4 `fn()` like ``` _p("Hello World") ->fn(htmlentities(...)) ->fn(str_split(...)) ->fn(array_map(...), strtoupper()) ->fn() ``` Proxied call to globally available functions ``` _p("Hello World") ->htmlentities() ->str_split() ->array_map(strtoupper(...))() ``` Instead of: ``` array_intersect( array_map( fn($val) => strtoupper($val), array_keys( array_flip(['name' => 'ade', 'hobby' => 'coding']) ) ), [0 => 'ADE'] ); //returns ['ADE'] ``` Or: ``` $arr = array_flip(['name' => 'ade', 'hobby' => 'coding']); // or array_values $arr = array_keys($arr); $arr = array_map(fn($val) => strtoupper($val), $arr); $arr = array_intersect($arr, [0 => 'ADE']); //$arr is ['ADE'] ``` > PS: You can still use the old `function() { return v; }`, `fn()` is the new short arrow function in PHP 7.4+ See: Installation ------------ [](#installation) - `composer require transprime-research/piper` Requirement ----------- [](#requirement) Minimum Requirement - PHP 7.2 + - Composer Other Usages ------------ [](#other-usages) ``` use Transprime\Piper\Piper; // Normal $piper = new Piper(); $piper->pipe(['AA'])->to('implode')->up(); // Better $piper->on(['AA'])->to('implode')(); ``` `piper()` function is a helper function. It is normally called like so: ``` // Nifty piper('AA')->to('strtolower')(); // Good Piper::on('AA')->to('strtolower')->up(); //Better Piper::on('AA')->to('strtolower')(); ``` Piper `piper()` function accepts a callable instance on the second parameter that would be immediately on the first parameter: ``` // test global method piper('NAME', 'strtolower') // NAME becomes name ->to(fn($name) => ucfirst($name)) ->up(); ``` Also accepts a class with an accessible method name. Say we have this class: ``` class StrManipulator { public function __invoke(string $value) { return $this->strToLower($value); } public static function strToLower(string $value) { return strtolower($value); } } ``` `StrManipulator` class can be passed in with a method like so: ``` // test class method piper('NAME', StrManipulator::class . '::strToLower') ->to(fn($name) => ucfirst($name)) ->up(); // test array class and method piper('NAME', [StrManipulator::class, 'strToLower']) ->to(fn($name) => ucfirst($name)) ->up(); ``` Even callable object is allowed like so: ``` // test class object piper('NAME', new StrManipulator()) // A class that implements __invoke ->to(fn($name) => ucfirst($name)) ->up(); ``` Please see `\Transprime\Piper\Tests\PiperTest` for more examples. Coming Soon ----------- [](#coming-soon) - Backward Pipe with `fro()` looking like: ``` piper('array_intersect', [0 => 'ADE']) ->fro('array_map', fn($val) => strtoupper($val)) ->fro('array_keys') ->fro('array_flip') ->fro(['name' => 'ade', 'age' => 5])(); ``` > Api implementation to be decided Additional Information ---------------------- [](#additional-information) See other packages in this series here: - \[A smart PHP if...elseif...else statement\] - \[A smarter Array now like an object\] - \[A smart PHP try...catch statement\] - \[A smart Carbon + Collection package\] - \[Jsonable Http Request(er) package with Collections response\] Similar packages ---------------- [](#similar-packages) - - Licence ------- [](#licence) MIT (See LICENCE file) ### Health Score 35 — LowBetter than 79% of packages Maintenance30 Infrequent updates — may be unmaintained Popularity27 Limited adoption so far Community11 Small or concentrated contributor base Maturity60 Established project with proven stability Bus Factor1 Top contributor holds 100% of commits — single point of failure How is this calculated?**Maintenance (25%)** — Last commit recency, latest release date, and issue-to-star ratio.
