Introduce templating helpers to allow replacing Twig as templating engine

[stloyd]

Second step to conquer the world

👍

Thanks, I didn't know this templating helper thing provided by Symfony.

Just one remark. Shouldn't you define some interfaces for these helpers ? And use them in the contructors of your extensions ?

[jjanvier]

Didn't see the WIP, maybe I talked too fast sorry...

[pjedrzejewski]

Definitely a 👍, but as @jjanvier said, I think interfaces would be nice here, what do you think @stloyd?

[stloyd]

I'm not sure about interfaces... mainly cause the logic is created by us, and saying we accept interface means that we don't know have no idea about logic anymore.

Symfony i.e. passes typehinted helpers (from which I have borred this idea), or even calls helper via container (due to DI scope problems [mostly when calling render() stuff], that twig as templating "scope" can't reference/call to other templating "scope").

[pjedrzejewski]

@stloyd I think you are right.

[stloyd]

@pjedrzejewski what do you think about this? (I will add CHANGELOG notes)

[pjedrzejewski]

@stloyd 👍, please add the changelogs and I'll merge it. Thanks!

[stloyd]

@pjedrzejewski Done =)
