Is there a way to share variables between template blocks?

I already opened an issue about this a week ago, but since those don't seem to be as active I thought I'd try my luck here as well:

I came up with the following template to create Anki card notes for the Obsidian_to_Anki plug-in:

<%*
    const decks = await app.vault.getAbstractFileByPath("Flashcards")?.children?.filter(f => f.children).map(d => d.name)
    const deck = await  tp.system.suggester(decks, decks)
    const title = await tp.system.prompt("Title")
    await tp.file.move(`/Flashcards/${deck}$/${title}`) 
    await tp.file.rename(`${title}`)
%>

TARGET DECK: // wanna use `deck` from above here

START
Basic
Front: // wanna use `title` from above here
Back: <% tp.file.cursor(1) %>
END

I get the deck it's supposed to go in as well as the title upfront. I use both to move the note to the correct location. And then I want to use both later on in the note again. I marked these spots with comments above. Is there a way to do that currently, without having to get them again?

Hey @jonasmerlin, if the template blocks are in the same template file, then you can re-use the deck variable in another block.

If you look at the doc (https://silentvoid13.github.io/Templater/docs/commands/execution-command), you can do things like that:

<%*
function log(msg) {
    console.log(msg);
}
%>
<%* log("Title: " + tp.file.title) %>

i.e. define a function in a block and use it in another. This works for variables as well of course.

Since you want to output something using an execution command (<%*) you have to use the tR variable as specified in the documentation.
In your use case, this would give something like that:

<%*
    const decks = await app.vault.getAbstractFileByPath("Flashcards")?.children?.filter(f => f.children).map(d => d.name)
    const deck = await  tp.system.suggester(decks, decks)
    const title = await tp.system.prompt("Title")
    await tp.file.move(`/Flashcards/${deck}$/${title}`) 
    await tp.file.rename(`${title}`)
%>

TARGET DECK: <%* tR += deck %>

START
Basic
Front: <%* tR += title %>
Back: <% tp.file.cursor(1) %>
END

Ohhh, I see. This works, thanks for the quick answer! (And thanks for all the work you put into this plug-in in the first place, of course, great work!)
