FAQ
Example:
In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
- Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
- To use Composer is sometimes complicated. Especially for beginners.
- Composer needs much resources. Sometimes they are not available on a simple webspace.
- If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
- Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

API
Recipes
This library comes with a few (most frequently used) built in recipes. These recipes define how functions are composed together.
- pipe: h(x) = g(f(x))
- map: h(list) = array_map(g, (array_map(f, list)))
- all: returns true if all functions (eg. f(x), g(x)...) return true.
- any: returns true if any function returns true.
To use any recipe, create new instance with their names passed into constructor.
You can create new recipes on the fly. Just pass in a closure.
You can define your own RecipeHandlers in your own code, and pass it to the recipe constructor.
Please take a look at RecipeHandler.php in this library to learn how to write your own handlers.
Caveat
- Functions composed with and recipes also accept as input.
- For and recipes, all functions are always evaluated regardless of their return values.
Testing
PHPUnit is overkill for this project. To do a simple test, execute and see if all assertions pass.
