Way to output text with counters similar to Tracker plugin?

[ReaderGuy42]

Is there a way to have dataview or dataviewjs output text like the Tracker plugin? I've been using that plugin but the issue with that is, it doesn't appear to be updated anymore and there are some issues.

So like, I'd like a counter for my book notes inside the current year's folder. So far, with the Tracker plugin, I had to add a variable to my note that looked like this BookCounter: 1. Then I had Tracker add up the values for BookCounter to get the number of books. That works, but I don't like having that extra variable in the frontmatter, especially since I also have a variable called Medium.

Would it be possible for have such a counter in dataview? One that procs (not sure I'm using that right) for each note that includes a Medium: Book, so that I can have a parallel counter for audiobooks, etc.

Thanks!

Maybe something like this:

dv.paragraph("Total Books:" + dv.pages().where(p => p.Medium == "Book").length)

OK, cool, last question (for now): Is there a way to output a date in the format of "day of the year", so like today would be 233 for 2022. I ask because I'd like to have a dynamic output that shows how many pages I should have already read at that point, reading a certain number of pages per day, and then subtracting that from the sum of pages of the books I've actually read. Thanks!

Dataveiw datetimes are luxon datetimes, so you can use the luxon docs: https://moment.github.io/luxon/api-docs/index.html#datetimetoformat. In this case, getting the day of year is date.toFormat("ooo").

That makes sense, but I can't figure out how to implement that into my code block. I've looked at that link and the documentation. Any pointers? Thanks!

What are you trying to render in full?

I'm working on my book tracker, so something that analyzes the frontmatter of my book notes, and e.g. adds up the values for Pages: , etc. Among other things, I have a goal of 50 pages reading per day, so I wanted to make a "goal" for that day, which I've now figured out:

let today = DateTime.now().toFormat("ooo");

dv.paragraph("# On this day, I should have read " + (today * 50) + " pages, so I've read " + (pagesum - (today * 50)) + " pages more than the goal of 50 pages per day.")

pagesum is another variable (?) that I define as the sum of the frontmatter values from Pages:

Thanks for the help :)

Now I'm still working on individual average ratings for books and audiobooks. I have a Rating variable, and averaging the overall rating works perfectly. But when I try narrowing it down to only doing books or audiobooks, the math doesn't seem to work out right. But that's not really that important.
