[KevinMarks] Can you do it with a nunjucks macro? That would let you keep state in a variable.

#
btrem [KevinMarks]++ thanks for replying yesterday re: keeping track of footnote numbers. Sorry, I only just now saw your reply. I think a macro would have the same problem. Each macro call is independent. It wouldn't know that it had already been called on that template.
#
btrem Or, if it could know, I can't think of how! ;-)

#
[KevinMarks] You can make a macro that is an external js function that can keep state
#
btrem [KevinMarks]: I can't imagine how. The problem as I see it as that every invocation of a shortcode or macro would be a new call to the js function. But I'm not a terribly advanced js programmer, so maybe I'm missing something.
#
Zegnat btrem: I have CSS add my footnote numbers so they are always in the right order
#
Zegnat Per this old article https://www.sitepoint.com/accessible-footnotes-css/
#
Zegnat (Just added it to /footnote on the wiki aswell)
#
[KevinMarks] Oh, maybe I have mixed up filters, which run in the node environment with macros, where I'm not sure <% set %> does what you want
#
btrem I hate to rely on stylesheets for something that is core content. It's a clever idea, but I'm sort of trying to do the same thing with 11ty/front matter/static html.
#
btrem [KevinMarks]: I don't think a <%set%> directive can be modified by a call to a macro or shortcode.
#
[tantek] btrem, I would feel weird about using styles for what amount to semantic numberings as well
#
Zegnat I liked it for the page I do it on, because it actually makes a partial sentence (multiple words) into the <a> that links to the explaining footnote. So the number is actually just an extra visual aspect to enhance the link
#
Zegnat Rather than the number being the link itself
#
Zegnat But also super obvious that the pattern might not cleanly apply to all sorts of content
#
btrem Zegnat: I can see how that might work. Though it's an unconventional way to mark footnotes. In a sense, I was trying to replicate css counters in my 11ty shortcode. So each footnote ref would have been {% fn %}. And the footnotes would be an array of strings in front matter. The second part is easy, and done. The first part probably can't be done.
#
[KevinMarks] Hm, so you're wanting a `yield` pattern

#
btrem Not sure what a `yield` pattern is. So, maybe?

[KevinMarks] The closest thing in nunjucks is a cycler - so you can set one up and call next() on it to get the next in sequence: https://mozilla.github.io/nunjucks/templating.html#cycler-item1-item2-itemn
#
[KevinMarks] ```{% set fn = cycler ("*", "†", "‡", "§", "‖", "⁑", "⁂") %}
#
[KevinMarks] In text {{fn.next()}} gives the next one```
#
[KevinMarks] Or, if you're Tantek:
#
[KevinMarks] In text {{fn.next()}} gives the next one```
#
[KevinMarks] ```{% set fn = cycler ("¹", "²", "³", "⁴", "⁵", "⁶", "⁷") %}
#
capjamesg Wow I have never seen someone use an asterism!
#
capjamesg I don't even know what ⁑ is 😂
#
capjamesg "two asterisks aligned vertically" https://graphemica.com/%E2%81%91 😂
