How to except title slide from total number of pages of pagination?

[moco-rocket]

Hello, I love this tool.
Is it possible to skip the title slide and appendix slides in the sum of page counts data-marpit-pagination-total? And how can I do so?

the pagination style of my css thema is this:

section::after {
    font-size: 1.1em;
    content: attr(data-marpit-pagination) ' / ' attr(data-marpit-pagination-total);
  }

And I wrote <!-- paginate: false --> at the title slide and <!-- paginate: true --> at the second slide, so the second slide' s pagination was "2/10." I want to change it to "1/9."

Unfortunately it cannot. data-marpit-pagination and data-marpit-pagination-total are determined from the count of actually rendered pages.

At a glance using CSS3 calc() function in theme looks like to be good, but content declaration is not supporting calc().

/* 🚫 This will not work */
section::after {
  font-size: 1.1em;
  content: calc(attr(data-marpit-pagination) - 1) ' / ' calc(attr(data-marpit-pagination-total) - 1);
}

Even if data-marpit-pagination could change the starting number through directive like <!-- paginate: 1 -->, the count of total pages can never change. You have to specify the number of total pages for your deck manually via inline <style> tag in Markdown.

We are welcome any ideas to implement for it.

I've assigned myself to get this in the next milestone, (modified) Marpit v2.

Proposal

paginate local directive is going to accept the extra value skip. Placing <!-- paginate: skip --> can skip increment of page number by the slide page.

---
paginate: true
---

Expect to render page number 1

---

Expect to render page number 2

---

<!-- paginate: skip -->

Skipped

---

<!-- paginate: true -->

Expect to render page number 3

Page number will not render in skipped pages as same as <!-- paginate: false -->.

It following the common rule of local directives so can skip multiple pages by one definition of <!-- paginate: skip -->

<!-- paginate: skip -->

Skipped

---

Skipped too

---

and more

---

<!-- paginate: true -->

Starting from page number 1

You can use spot directive by adding underscore prefix <!-- _paginate: skip --> to skip exactly single page.

---
paginate: true
---

Page 1

---

<!-- _paginate: skip -->

Skipped

---

Page 2

---

Page 3

data-marpit-pagination-total attribute will point out the page number shown in the end of slide as the total page. That's taking skipped pages into account, but it may be debatable.
