I know this is subjective & personal, but I actually prefer the more explicit (and somewhat more verbose) syntax of naming each attribute specifically:
◊essay[#:title "Title" #:url "http://url.com"]{The Blurb to this essay} I can’t comment on possible changes to Pollen to accommodate syntax style preferences. But looking at your specific example here did make me wonder if backing up a bit might be helpful. Is your ◊essay tag likely to be used often throughout your site, or just once in an index/listing of essays? Are these essays also Pollen files or are they external web pages that you are linking to? Here’s where I’m going with this. Suppose your answers to the question above are "yes, using often throughout" and "yes" respectively. In that case, one route would be to make the tag look more like this: ◊essay["my essay"] ...and that’s it. The tag function would then, for example, convert "my-essay" to "my-essay.html.pm" and pull the title, url and blurb out of the metas for that file: (define (essay mykey) (define mykey-recode (string-append (string-replace mykey " " "-") ".html.pm")) (define mykey-sym (string->symbol mykey-recode)) (define essay-metas (get-metas (string->path mykey-recode))) `(a [[href ,(select-from-metas 'url essay-metas)] [title ,(select-from-metas 'title essay-metas)]] (i ,(select-from-metas 'blurb essay-metas)))) At the top of my-essay.html.pm, you’d fill in the metas like so: ◊(define-meta title "This Essay’s Title") ◊(define-meta url "http://url.com";) ◊(define-meta blurb "The blurb for this essay") Thus begins the essay: Lorem ipsum dolor sit amet… That way I have less typing, my tag syntax is much simpler, and I can change that info once (in the essay itself) and have it update everywhere. Again, I know I made a lot of assumptions there. On Wednesday, September 28, 2016 at 4:46:32 PM UTC-5, Shrutarshi Basu wrote: > > Sure.
