Increase the robustness with reduced amount of code. At the moment, in the experimental phase. **[Documentation](https://munusphp.github.io/docs/start)** Due to the lack of generic types, Munus achieves genericity with the help of [PHPStan](https://phpstan.org/blog/generics-in-php-using-phpdocs) `template` annotation. Stream example: find the sum of the first ten squares of even numbers ``` Stream::from(1) ->filter(fn($n) => $n%2===0) ->map(fn($n) => $n**2) ->take(10) ->sum(); ``` Other examples: ``` /** @var Stream $stream */ $stream = Stream::range(1, 10)->map(function(int $int): int {return $int * 5}); /** @var Option $option */ $option = Option::of(domainOperation()); /** @return Either */ function domainOperation(): Either {} /** @var TryTo $result */ $result = TryTo::run(function(){throw new \DomainException('use ddd');}); $result->getOrElse(new Result()) ``` The goal is to help achieve: **Psalm was able to infer types for 100% of the codebase** ### Features [](#features) **Values:** - TryTo - Either - Option - Lazy **Collections:** - Set - Stream (implemented as lazy linked list) - GenericList (implemented as immutable linked list) - Iterator **Other:** - Tuple ### Roadmap [](#roadmap) - Pattern matching - Property checking Inspiration ----------- [](#inspiration) This library is inspired by [vavr.io](https://www.vavr.io/) License ------- [](#license) Munus is released under the MIT Licence.
