[chef] How to pass a variable to another recipe?

[Robert Freiberger < >]

Hello Chef, 

I have a recipe that copies a file over from <cookbook>/files/default/myscript.rb to the node locally. Right now I have this hard coded where it's using the name listed in the recipe, but I would like to make this use a variable listed in another recipe. 

So the end goal would be a recipe like launch_script.rb would call the script copy the file over using the copy recipe, only based upon a variable name listed in the launch_script.rb recipe. 

From what I found, this is only possible using a node runtime like

node.run_state[:script_1] = "check_httpd.rb"

filename = node.run_state[:script_1]

But this still requires me to add the "node.run_state[:script_1] added to the copy recipe. 

Is there any way to send a variable to a recipe without hardcoding the name in the recipe? Or what is really the correct Chef way? Create a new resource?

Thanks,

Robert
