Adding context to twig extension

[smurfy]

This pull requests addes the ability to set the context in twig.

i mainly need groups in the extension but only that would be bad for people which want to use versions aswell.

if this solution is accepted i could create a patch for serializerBundels Templating aswell.

I guess you pass the context to the template, or how do you create it?

[smurfy]

yea exactly, another way would be better i guess maybe an array option like

{{ object|serializer('json', { 'groups' : ['foo', 'bar']}) }}

[schmittjoh]

That would be an option yeah, and should work well for the built-in things.

Another idea, what do you think about something like:

{{ object|serialize('json', serialization_context().groups(['foo', 'bar'])) }}

[smurfy]

I like it, its a bit long, but better than assign the context from the controller.
And it should work even if more options get added to the context, without adding logic to the extension.

[schmittjoh]

Great, could you update your PR?

[schmittjoh]

Please also add a type hint to the parameter.

[smurfy]

sure, i will do it tomorrow.

Ok updated my code. had to change groups to setGroups and possible version to setVersion.

Sample

{{ data|serialize('json', serialization_context().setGroups(['foo', 'bar'])) }}

{{ data|serialize('json', serialization_context().setVersion('1.0')) }}
