#Full API ##Smartfs

• smartfs( name ) - returns the form regisered with the name 'name'
• smartfs.create( name,function ) - creates a new form and adds elements to it by running the function. Use before Minetest loads. (like minetest.register_node)
• smartfs.element( name, data ) - creates a new element type.
• smartfs.dynamic( formname, playername ) - creates a dynamic form. Returns state. See example.lua for example. Remember to call state:show()
• smartfs.add_to_inventory(form, icon, title) - Adds a form to an installed advanced inventory. Returns true on success.
• smartfs.inventory_mod() - Returns the name of an installed and supported inventory mod that will be used above, or nil.
• smartfs.override_load_checks() - Allows you to use smartfs.create after the game loads. Not recommended!
• smartfs.nodemeta_on_receive_fields(nodepos, formname, fields, sender) - on_receive_fields callback can be used in minetest.register_node for nodemeta forms

##Form

• form:show( playername [, parameters] ) - shows the form to a player. See state.param.
• form.name - the name of the form.
