Pollen templates can do all this too, for a not-very-surprising reason (keep reading) ... > I started fiddling with it in a Pollen project and, come to realize it was > working even though I hadn’t `require`d or `provide`d any functions from > web-server/template. How is this possible, I think. Some digging revealed > that Pollen implements its own `include-template` function—and that it is > provided automatically for code inside a Pollen template. The `include-template` in Pollen is the same one as in `web-server/templates` [1] But I copied its source and changed it so that it could return binary files (like PDFs), which the usual one cannot. > have you thought about including it in the docs?

I've just never been clear what could be done with `include-template` directly that isn't already possible through existing Pollen functions. When you apply a template to a markup source during a render, you're already using `include-template`. > might it also be worth providing or reimplementing web-server/template's `in` > function?

Same — I suppose I've always thought that because Pollen has a notion of X-expressions and tag functions, they subsume `in` (which, unlike `include-template`, does no heavy lifting anyhow) [1] https://github.com/mbutterick/pollen/blob/master/pollen/private/include-template.rkt <https://github.com/mbutterick/pollen/blob/master/pollen/private/include-template.rkt> -- You received this message because you are subscribed to the Google Groups "Pollen" group.
