Changing choice node text after moving to next position

[benlubas]

I'd like to make a snippet that gives you choices like today, tomorrow, next week

c(1, t"today", t"tomorrow", t"next week")

But then after I leave the choice node, whichever choice was selected is transformed into the actual date.

I've played around with function nodes and callbacks, but I'm not sure how to force a function node to re-compute from within a callback. Is this something I could do?

Mhhh implementing this exactly as you state is difficult because you'd have to put the choiceNode inside a dynamicNode to change it, and updating from inside the dynamicNode is currently forbidden.

But I have another suggestion that should be similarly good: As I understand it, you're essentially using the choiceNode to put easily readable labels to less-readable dates.
I'd implement this by using ext_opts to show this readable lable, while just switching between the already-correct choices:

local function date_at(when)
	return d(1, function()
		local out = vim.system({"date", "--iso-8601", "-d", when}):wait()
		-- remove trailing \n
		local datestring = out.stdout:sub(1,-2)

		return sn(nil, {i(1), t(datestring)}, {node_ext_opts = {active = { virt_text = {{when, "Comment"}} }}})
	end)
end

s("date", {
	c(1, {
		date_at("today"),
		date_at("tomorrow"),
		date_at("next week"),
	})
})

(note that this does not work on current master, you need the patches in self-dependent-dNode/#1137)

I was thinking about something like this, thanks!
