Right now my figures and tables are automatically numbered "Figure 1" ,"Figure 2" etc. I would like the number to reflect what section it is in, i.e. if it is the third figure in chapter 5, it should be "Figure 5.3". How can I accomplish this?
#Figure and table numbering

figure has a few options at your disposal
for example, numbering: accepts a function which lets you entirely customize the number
the function takes the number of the figure as an argument
and returns [content] with the text to display
to have what you're looking for in an automatic manner, you'll probably need to use a custom counter
e.g. counter: counter("figcounter") <--- this is also an option you can give to figure
and then do something like
#show heading.where(level: 1: it => {
counter("figcounter").update((counter(heading), 1))
it
})```to reset the counter on every level 1 heading (for example)
actually I think just the counter is necessary
let me give this a shot:
?render
#set heading(numbering: "1.")
#show heading.where(level: 1): it => {
counter(figure.where(kind: "figcounter")).update(0)
it
}
#let fignumbering = n => locate(loc => {
let section = counter(heading).at(loc).map(str).join(".")
[#section.#n]
})
= My section
#figure(supplement: "Figure", kind: "figcounter", numbering: fignumbering, caption: [Test])[a]
#figure(supplement: "Figure", kind: "figcounter", numbering: fignumbering, caption: [Test])[b]
= Other
#figure(supplement: "Figure", kind: "figcounter", numbering: fignumbering, caption: [Test])[a]
#figure(supplement: "Figure", kind: "figcounter", numbering: fignumbering, caption: [Test])[b]

#set heading(numbering: "1.")
#show heading.where(level: 1): it...

oh ok you cant define the counter
you actually have to set the figure 'kind'
ok hold on
there we go @hollow cypress
if you want to avoid this "supplement", "kind" business, you can reset the counter for all figures on each heading
?render
#set heading(numbering: "1.")
#show heading.where(level: 1): it => {
counter(figure.where(kind: table)).update(0)
it
}
#let fignumbering = n => locate(loc => {
let section = counter(heading).at(loc).map(str).join(".")
[#section.#n]
})
= My section
#figure(numbering: fignumbering, caption: [Test], table[a])
#figure(numbering: fignumbering, caption: [Test], table[a])
= Other
#figure(numbering: fignumbering, caption: [Test], table[b])
#figure(numbering: fignumbering, caption: [Test], table[c])

like that I changed it to reset for tables only
at the top
note that the counter isnt reset on sub-headings; you can override this behavior by removing the .where(level: 1) from the heading selector at the top
like so:
?render
#set heading(numbering: "1.")
#show heading: it => {
counter(figure.where(kind: table)).update(0)
it
}
#let fignumbering = n => locate(loc => {
let section = counter(heading).at(loc).map(str).join(".")
[#section.#n]
})
= My section
#figure(numbering: fignumbering, caption: [Test], table[a])
#figure(numbering: fignumbering, caption: [Test], table[a])
== Subsection
#figure(numbering: fignumbering, caption: [Test], table[a])
#figure(numbering: fignumbering, caption: [Test], table[a])
= Other
#figure(numbering: fignumbering, caption: [Test], table[b])
== Sub
#figure(numbering: fignumbering, caption: [Test], table[a])
=== Sub sub
#figure(numbering: fignumbering, caption: [Test], table[c])
#figure(numbering: fignumbering, caption: [Test], table[a])

@chrome mesa you're amazing. thank you!
chrome mesa
np 👍

It is working well, but I have a problem that when I use
#outline(
title: [List of Figures],
target: figure.where(kind: image),
)
at the top, the links to the figures are labeled as Figure 0.1 etc.
@chrome mesa any ideas?
chrome mesa
oh, yeah thats weird
I think it's because like
it's taking the numbering function to the outline
and so the location is set to before any heading is placed
so it goes to 0
there really needs to be some sort of thing in typst where it saves the final content of something and just takes it to the outline
or at least saves the location
@hollow cypress can you open an issue on GitHub?
maybe we can try to work on a fix or smth
chrome mesa
no prob
so
I think I see the problem in the internal code, but it seems that it'd be kinda annoying to fix maybe
so this is the function which figure uses to determine what to display on the outline
it shows caption with the given vt where vt is the context
and this is called from the outline element
with the outline's context
so indeed
I think it's using the outline's context
but this doesn't seem easy to fix at all
lol
cuz it has to use some context
ideally it would cache the context somehow
from where it's placed and take it to the outline on the next redraw
but not sure how to do that in the best way
anyways
this is something that I will comment on the issue when it is opened
well to say that vt is the "context" is a bit of an oversimplification as well
cuz it has introspection capabilities which allow accessing things outside the current context
but still I think the issue is something along those lines
ok
I think I am seeing the light
or maybe not
well I could try something
@hollow cypress can u send ur sample document later? I wanna do some experiments
