Custom Handler: Marks

[chrisgrieser]

shows marks with their letter in the scrollbar. excluded_marks are excluded (duh). special marks (non-letters) and global marks are not included to avoid cluttering – only manually assigned marks are displayed.

🥳

require("scrollbar.handlers").register("marksmarks", function(bufnr)
	local excluded_marks = "z"
	local marks = fn.getmarklist(bufnr) ---@diagnostic disable-line: param-type-mismatch
	local out = {}
	table.insert(out, {line = 0, text = ""}) -- ensure at least one dummy element in return list to prevent errors when there is no valid mark

	for _, markObj in pairs(marks) do
		local mark = markObj.mark:sub(2, 2)
		local isLetter = mark:lower() ~= mark:upper()
		if isLetter and not (excluded_marks:find(mark)) then
			table.insert(out, {
				line = markObj.pos[2],
				text = mark,
				type = "Info",
				level = 6,
			})
		end
	end
	return out
end)
