Informations about the package exception-parser
RollerworksExceptionParser
This package provides the Rollerworks ExceptionParser which extracts exception-data to an array.
Basically it wraps multiple exception-catch blocks into one call, and returns the parsed information.
Installation
1. Using Composer

Or manually, by adding the following to your
composer.json file:
Then, you can install the new dependency by running Composer's update
command from the directory where your composer.json file is located:
Note: This package is stand-alone, composer is only used for generating the autoloader class.
You can also use your own autoloader, but make sure its PSR-4 compatible. See the composer.json file in this package for mapping information.
Usage
Usage is very simple, each exception that you want to process needs a compatible parser which parses the Exception to an array.
The ExceptionParserManager passes trough all the registered exception-parses in order of registration, till one accepts the exception.
When no compatible parser is found an empty array is returned instead.
Exception class
Exception Parser
The SearchFieldRequiredExceptionParser exception parser
parses the FieldRequiredException shown above.
ParserManager
Now register the Parser at the ExceptionParserManager.
Note: You can register as many processors as needed.
Key transforming
The ExceptionParserManager also allows to transform the array-key to another format like '{{ name }}'.
'{var}' is the placeholder which is replaced by the current key.
Or you can use a callback that returns the transformed key. This is very useful if the keys contains a prefix or is wrapped inside a special format.
Note: If the callback returns null or void the key is added as incrementing index. Only when the "callback" returns null or void, setting null as constructor value is the default and will not transform the array-keys.
