I’m about to create custom helpers to provide some SVG image embedding functionality, and I’ll need to know how helpers actually work to make the site efficient. Do I understand properly, that each page is generated running all the helpers in the template, and then everything is cached?
It would also be important to know what kind of context data is available in a helper? In my implementation, there would be many helper calls on each template, and all the calls would need to see the parameters of other calls. Can I do that in some way?
(I think my question is not version nor configuration dependant)
