change highlight of a given node

[pwntester]

Hi,

Im reviewing the code for node and tree but can figure out how to change a node highlight. I want to add a global mapping that search for the node in the tree (✅), goes to the node (✅), and adds a special highlight. I cant figure out this last part, could you please show me an example?

Thanks

-- consider create a stateful decorator saves the node's path
local MyDefault = {}

function MyDefault:decorator()
    return function(node)
        if self.selected and self.selected == node.abs_path then
            return node.name, '<YourAwesomeHighlight>'
        end
        return decorators.default(node)
    end
end

-- use this decorator replacing the default
tree:setup({
    draw_opts = {
        decorators = {
		    -- ...
            -- decorators.default,
            MyDefault:decorator(),
			-- ...
        },
    },
	-- ...
})

-- setting `selected` when you find your target file
 	MyDefault.selected = node.abs_path
	tree:force_refresh_node(node)

-- dont forget to clear `selected` when you don't need the special highlight
