Modular computer programs

How module computer programs work

Ok. so a quick rundown on how to make a program. This is kind of a shitty documentation, but oh well I was asked to.

This is how the base program is setup. the rest is mostly tgui stuff. I'll use the ntnetmonitor as a base

/datum/computer_file/program/ntnetmonitor
	/// This is obviously the name of the file itself. not much to be said
	filename = "ntmonitor"

	/// This is sort of the official name. it's what shows up on the main menu
	filedesc = "NTNet Diagnostics and Monitoring"

	/// This is what the screen will look like when the program is active
	program_icon_state = "comm_monitor"

	/// This is a sort of a description, visible when looking on the ntnet
	extended_desc = "This program is a dummy."

	/// size of the program. Big programs need more hard drive space. Don't
	/// make it too big though.
	size = 12

	/// If this is set, the program will not run without an ntnet connection,
	/// and will close if the connection is lost. Mainly for primarily online
	/// programs.
	requires_ntnet = 1

	/// This is access required to run the program itself. ONLY SET THIS FOR
	/// SUPER SECURE SHIT. This also acts as transfer_access as well.
	required_access = access_network

	/// This is the access needed to download from ntnet or host on the ptp
	/// program. This is what you want to use most of the time.
	transfer_access = access_change_ids

	/// If it's available to download on ntnet. pretty self explanatory.
	available_on_ntnet = 1

	/// ditto but on emagged syndie net. Use this for antag programs
	available_on_syndinet = 0

	/// Bitflags (PROGRAM_CONSOLE, PROGRAM_LAPTOP, PROGRAM_TABLET combination)
	/// or PROGRAM_ALL. Use this to limit what kind of machines can run the
	/// program. For example, comms program should be limited to consoles and laptops.
	usage_flags = PROGRAM_ALL

	/// This one is kinda cool. If you have the program minimized, this will
	/// show up in the header of the computer screen. You can even have the
	/// program change what the header is based on the situation! See `alarm.dm`
	/// for an example.
	var/ui_header = "downloader_finished.gif"

Now. for pre-installing stuff.

Primarily done for consoles, there's an install_programs() proc in the console presets file in the machines folder.

for example, the command console one.

/obj/machinery/modular_computer/console/preset/command/install_programs()
	cpu.hard_drive.store_file(new/datum/computer_file/program/chatclient())
	cpu.hard_drive.store_file(new/datum/computer_file/program/card_mod())

Basically, you want to do cpu.harddrive.store_file(new/_program path here()) and put it in the subtype's install_programs(). Probably pretty self explanatory, but just in case.

Will probably be expanded when new features come around or I get asked to mention something.
