[Config] Enable injection of service reference or definition into configuration nodes #62142
Closed as not planned
Description
Description
With the PHP configuration format, it's possible to set PHP objects (while Yaml has restricted types, extended using tags).
Benefit: define service directly in the configuration, so that they are colocated.
That would also enable other types of objects; each node allowing a list of class names.
Example
In framework.cache.pools.*.adapter, the config node only accepts a string for the service Id.
It could accept a Reference:
return App::config([
'framework' => [
'cache' => [
'pools' => [
'cache.mycache' => [
- 'adapter' => 'cache.adapter.redis',
+ 'adapter' => reference('cache.adapter.redis'),
'default_lifetime' => 3600,
],
],
],
],
]);Or inline service Definition:
return App::config([
'framework' => [
'cache' => [
'pools' => [
'cache.mycache' => [
- 'adapter' => 'cache.adapter.redis',
+ 'adapter' => inline_service(RedisAdapter::class)->...,
'default_lifetime' => 3600,
],
],
],
],
]);The configuration tree would be like this:
->prototype(['string', Definition::class, Reference::class])
