Ds84182: Halfway finished rewriting this page.

[http://www.computercraft.info/forums2/index.php?/topic/10216-wip-cclights2-opensource-now-on-github/ CCLights2] is an Open Source Minecraft mod that adds a GPU peripheral, and monitors to suit your need. Unlike CCGPU, this mod does not use OpenGL, but it is Multiplayer Compatible.

Os.pullEvent

Ds84182: Added event turtle_inventory for 1.55 update

{{lowercase}}
{{Function
|name=os.pullEvent
|args=[<nowiki></nowiki>{{type|string}} filter]
|api=OS
|returns={{type|string}} event, variable parameters(see table below)
|addon=ComputerCraft
|desc=Waits (yields) until an event occurs
|examples=
{{Example
|desc=The program requires to wait for a keypress to do something:
|code=[[Function (type)|function]] clear()
[[term.clear]]()
[[term.setCursorPos]] (1,1)
end
while true do
clear()
[[print]] ("Press E to do something.")
local event, param1 = os.pullEvent ("char") -- limit os.pullEvent to the char event
if param1 == "e" then -- if the returned value was 'e'
clear()
[[write]] ("Name: ")
local name = [[read]]()
[[print]] (name)
break
else
clear()
[[print]] ("Wrong button!")
[[os.sleep|sleep]] (1.5) -- I don't like a whole 2 seconds but 1 second is too short
end
end
}}
}}

=== Common syntax ===

event, param1, param2, param3 = os.pullEvent()

Note: This is one of the most commonly used functions that can return multiple values.
It works like any other function call (such as "input = read()") except that you can get more than one piece of information back.

== How it works ==
When os.pullEvent() is called, the computer waits until an event occurs.
Events can be triggered by several different things, such as a key being pressed or a redstone input changing.
They are usually triggered by ComputerCraft itself, when it needs to notify the computer that something happened.
They can also be triggered by peripherals, or by your program calling [[os.queueEvent]].

More complicated input, such as "the user typing a line of text," does ''not'' correspond to an event.
[[read]] handles this inside itself by waiting for the user to press a key, then updating the screen, moving the cursor, etc.

Events have a type (which is a string) and 0-5 parameters (which are often but not always strings).
No built-in events use more than 3 parameters.

When an event occurs, the event type, followed by the parameters, will be returned. If you have:

event, button, x, y = os.pullEvent()

and the user clicks the mouse at coordinates 5,4 then:
* event will be set to "mouse_click" (the event type)
* button will be set to 0 (the first parameter)
* x will be set to 5 (the second parameter)
* y will be set to 4 (the third parameter)

Note that in this example, we didn't specify a filter. If you specify a filter, then all events of different types will be ignored.
If the user inserts a disk, instead of clicking the mouse, then event will be "disk", button will be the side the disk drive is on, and x and y will be nil.

If we wanted to only wait for mouse clicks we could use:

event, button, x, y = os.pullEvent("mouse_click")

which will ignore any events that are not mouse clicks.

If you assign more variables than necessary, the extra ones will be set to nil.
If you assign fewer variables than necessary, the extra parameters will be discarded.

IO (API)

2013-07-11T19:41:39Z

Ds84182: Forgot a number! Updated for 1.55

IO is a reimplementation of the default Lua input / output API defined [http://www.lua.org/manual/5.1/manual.html#5.7 here], with some features trimmed. Most features should work. If you find a non-working feature, please list it here.

List of non-working features from IO as of ComputerCraft 1.55:

* io.open: Modes “a+”, “r+”, and “w+” are not supported.
* io.popen: Doesn’t exist.
* io.read: Only allows format string “*l”.
* io.tmpfile: Doesn’t exist.
* file:read: Doesn’t support format string “*n” or a character count.
* file:seek: Doesn’t exist.
* file:setvbuf: Doesn’t exist.

All of the capabilities in this API are also available in the [[Fs (API)|Fs API]], along with some other functions not directly related to reading and writing individual files.

[http://www.computercraft.info/forums2/index.php?/topic/10216-wip-cclights2-opensource-now-on-github/ CCLights2] is an Open Source Minecraft mod that adds a GPU peripheral, and monitors to suit your need. Unlike CCGPU, this mod does not use OpenGL, but it is Multiplayer Compatible.
