Laptop Mod API

Node creator helpers

laptop.os_get(pos) - Get an OS object. Usefull in on_construct or on_punch to initialize or do anything with OS Needed in on_receive_fields to be able to call os:receive_fields(fields, sender) for interactive apps
laptop.after_place_node / laptop.after_dig_node - (optional) can be used directly for node definition. Move laptop apps data to ItemStack if digged and restored back if placed again. So you can take along your laptop. Note: you need to set stack_max = 1 because the data can be stored per stack only, not per item.

Operating system calls

Usable from node functions, from apps or outsite

local os = laptop.os_get(pos) - Get the Operating system object. pos is the node position

os:power_on(new_node_name) - Activate the app "launcher" and if given swap node to new_node_name
os:resume(new_node_name) - Restore the last running app after power_off. if given swap node to new_node_name
os:power_off(new_node_name) - Remove the formspec and if given swap node to new_node_name
os:swap_node(new_node_name)- Swap the node only without any changes on OS
os:set_infotext(infotext) - Set the mouseover infotext for laptop node
os:save() - Store all app-data to nodemeta. Called mostly internally so no explicit call necessary
os:set_app(appname) - Start/Enable/navigate to appname. If no appname given the launcher is called
os:receive_fields(fields, sender) - Should be called from node.on_receive_fields to get the apps interactive
os:get_theme(theme)- Get theme data current or requested (theme parameter is optional)
os:set_theme(theme)- Activate theme
os.custom_launcher - Replacement for default "launcher" app. Can be set/changed in node constructor or anytime at runtime

App Definition

laptop.register_app(internal_shortname, { definitiontable }) - add a new app or view

app_name - App name shown in launcher. If not defined the app is just a view, not visible in launcher but can be activated. This way multi-screen apps are possible
app_icon - Icon to be shown in launcher. If nothing given the default icon is used
app_info - Short app info visible in launcher tooltip
fullscreen - (boolean) Do not add app-background and window buttons
view - (boolean) The definition is a view. That means the app/view is not visible in launcher
formspec_func(app, os) - Function, should return the app formspec (mandatory) During definition the "app" and the "os" are available
receive_fields_func(app, os, fields, sender) Function for input processing. The "app" and the "os" are available inside the call laptop.register_view(internal_shortname, { definitiontable }) - add a new app or view same as register_app, but the view flag is set. app_name and app_icon not necessary

App Object

local app = laptop.get_app(internal_shortname, os) - Give the app object internal_shortname, connected to given os. Not necessary in formspec_func or receive_fields_func because given trough interface

data = app:get_storage_ref(appname) - Returns a "persitant" data table that means the data in this table is not lost between formspec_func, receive_fields_func, apps-switch or on/off. Appname is optional to get data from other app
`app:back_app() - Go back to previous app/view
`app:exit_app() - Delete call stack and return to launcher

Theme definition

laptop.register_theme(name, definitiontable) - add a new theme. All parameters optional, if missed, the default is used Definitiontable:

launcher_bg Launcher background image
app_bg Apps background image
back_button Back Button image
exit_button Exit button image
major_button Major (highlighted) button image
minor_button Minor button image
