Changelog 1.6.0 — 25th of August 2023

Notable changes

Symfony Bundle

A bundle is now available for Symfony applications, it will ease the integration and usage of the Valinor library in the framework. The documentation can be found in the CuyZ/Valinor-Bundle repository.

Note that the documentation has been updated to add information about the bundle as well as tips on how to integrate the library in other frameworks.

PHP 8.3 support

Thanks to @TimWolla, the library now supports PHP 8.3, which entered its beta phase. Do not hesitate to test the library with this new version, and report any encountered issue on the repository.

Better type parsing

The first layer of the type parser has been completely rewritten. The previous one would use regex to split a raw type in tokens, but that led to limitations — mostly concerning quoted strings — that are now fixed.

Although this change should not impact the end user, it is a major change in the library, and it is possible that some edge cases were not covered by tests. If that happens, please report any encountered issue on the repository.

Example of previous limitations, now solved:

// Union of strings containing space chars
(new MapperBuilder())
        "'foo bar'|'baz fiz'",
        'baz fiz'

// Shaped array with special chars in the key
(new MapperBuilder())
        "array{'some & key': string}",
        ['some & key' => 'value']

More advanced array-key handling

It is now possible to use any string or integer as an array key. The following types are now accepted and will work properly with the mapper:

$mapper->map("array<'foo'|'bar', string>", ['foo' => 'foo']);

$mapper->map('array<42|1337, string>', [42 => 'foo']);

$mapper->map('array<positive-int, string>', [42 => 'foo']);

$mapper->map('array<negative-int, string>', [-42 => 'foo']);

$mapper->map('array<int<-42, 1337>, string>', [42 => 'foo']);

$mapper->map('array<non-empty-string, string>', ['foo' => 'foo']);

$mapper->map('array<class-string, string>', ['SomeClass' => 'foo']);
