I don't think so. Perhaps with Global_Lua_Modules/Loops although it isn't very well-documented. Or with the loops extension.

Seems a bit complicated.

In fact I was trying to create a navbox with links to episodes (1 to 200+), but I'm still creating the pages of the episodes (as they are released), and I didn't want to keep updating the navbox every time a new episode is included, and didn't want red links there either.

So I went through the more rustic path and just added 250 lines, one for each episode, and used the magic word PAGESINCAT to check the amount of links that should be included.

Do you mean that the loops extension is complicated to use?

I meant Lua/Loops. The loops extension was kind of what I was looking for, but I didn't want to request an extension just for that template.

It shouldn't be too complicated to just create a short module to do that right?

I have no idea. I looked through a bunch of wikis expecting to find something similar (navbox? list of episodes? Fandom? should be a thing), but had no chance because most wikis would list episodes with their names, and not the numbers.

local t = {}
for i = 1, frame:callParserFunction('PAGESINCAT', 'Capítulos'), 1 do
	table.insert(t, frame:expandTemplate({title = 'Nav capítulos/cap', args = {i}}))
end
return table.concat(t)

I haven't tested this function but surely you could just make something that looks like this
