The best way to change options dynamically (e.g. on keymap)

[alex35mil]

I want to change the path setting of the filename component when I hit a keymap. What would be the best way to do it?

{ "filename", path =  <dynamic>  }

This is what I came up with:

set(
    { "n", "i", "v" },
    "<C-l>",
    function()
        local plugin = require "lualine"
        local config = plugin.get_config()
        for _, section in pairs(config.sections) do
            for _, component in ipairs(section) do
                if type(component) == "table" and component[1] == "filename" then
                    if component.path == 0 then
                        component.path = 1
                    else
                        component.path = 0
                    end
                end
            end

        end
        plugin.setup(config)
    end
)

I'm not sure if it is safe to call the setup function multiple times.
