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.

Variables
The Setherator Variable management library. Manages and processes variable values with some additional magic.
Install
Via Composer
Usage
A compilation of several use cases of Variables and it's helpers.
Will result in:
Helpers
A variable value can be any scalar, array, object type but also closure which will be executed and cached. To prevent caching value should implement NonCacheableClosure interface for e.g. factory helper function.
Reference
A function to fetch variable value from Variables instance. If not found $default = null will be returned. If raw value before evaluation required use $raw = true.
To fetch value at variable get time use these functions.
Enviroment variable
A function to fetch environment variable. If not found $default = null will be returned.
Context
A function to wrap your closure and inject context from Variables::getContext();
Will return your closure wrapped with context variables + extra $args as arguments. $args will be evaluated using Variables::parseValue() function. It will behave as normal Variable value.
Attention: Context returned closure does not accept any arguments.
Factory
A function to prevent your closue value from getting cached. Your closure will be called everytime value is accessed. $args will be passed as arguments to closure function. $args will be evaluated using Variables::parseValue() function. It will behave as normal Variable value.
Will return a value which implements NonCacheableClosure interface and prevents it from caching and behave as your normal closure.
All
A function to evaluate all values passed to arguments and return result as array.
Will return an array of all $args evaluated.
Tip: To evaluate all values at variable get time use function: allFn(/* ... */).
Logic
A function to evaluate condition and decide which value to use. $condtion, $true, $false are evaluated using Variables::parseValue() function.
Will return a closure which will decide which $true or $false to return based on $condition
Attention: Logic returned closure does not accept any arguments.
Passthrough
A function which will pass all evaluted values as argumnents to closure.
Will return a closure which will pass $args evaluated as arguments to Closure.
Attention: Passthrough returned closure does not accept any arguments.
First
A function which return a first truthfull value from arguments. $args will be evaluated using Variables::parseValue() function.
Tip: To evaluate at variable get time use function: firstFn(/* ... */).
Value Parsers
You can implement your own value parsers to be parsed when accessing variables value.
