  1. Firstly you're mixing up file:read and file:write.. One writes to the file and the other reads. local config = {} for line in io.lines "/path/to/config.txt" do table.insert(config, line) end print(config[3]) -- # 3rd line in your config -- # this is probably the simplest way but there are others. To read a specific line in a file you'd have to know the exact offset of bytes until the information you're trying to read.
  2. It writes to the current line of a new file, so in this case it'd be the 1st line. To read the first line just open the file in read mode ` file = io.open("myfile", "r") Ip = file:read("*l") file:close() ` *l reads 1 line from a file 1 reads one byte from a file
  3. file = io.open("/path/to/config.txt", "w") file:write(newIP) file:close()

    Bummer.. I guess because user input is not strictly a file it's not behaving the way I expected.. perhaps you'll have to roll your own user input with event.pull..

    I could be wrong about io.read... perhaps post your code so I can see what's going on.

    Io.read should yield the thread until enter is hit or the arg to it is satisfied ie after 2 characters. setCursorBlink will only set the blink mode of the cursor

    To limit the number of characters read you can pass a number to io.read. i.e `io.read(2)` As for the cursor blinking and overwriting your input box you can either make your input box larger or turn the cursor blinking off with `term.setCursorBlink(false)`

    The lib you're looking for are cursor.lua & full_cursor.lua but I'm not sure these will do what you're seeking to accomplish I just remember hearing about them... Also my example was done in a way that it could be modified to control the windows(and thus the cursors) of other processes. If you just want to access the current processes window it may be simpler with the tty lib. local tty = require "tty" local event = require "event" local kb = require "keyboard" local window = tty.window local handle = event.listen("touch", function(_, _, x, y) window.x = x window.y = y print "HI" end) while true do local ev = { event.pull("key", nil, nil, kb.keys.q) } event.cancel(handle) break end

    Was this any help? I forgot, but there is actually a cursor library in the later versions of openos that you might want to check out.. I haven't used it and I'm not familiar with it at all but that might be a better solution.

    okay so its a bit tricky cause i dont know what exactly you're trying to pull but ill give it a shot... local term = require "term" local kb = require "keyboard" local event = require "event" local process = require "process" local component = require "component" local window = term.internal.open() -- # creates a full screen window. optionally provide (dx, dy, width, height) term.bind(component.gpu, window) -- # bind the primary gpu to the window we made local proc = process.info() -- # get an instance of this process' details local handle = event.listen("touch", function(_, _, x, y) -- # this is basically your 'cursor' function proc.data.window.x = x proc.data.window.y = y print "HI" -- # click around to see the effect end) while true do local ev = {event.pull("key")} if ev[4] == kb.keys.q then break end -- # quit the loop and basically the program end event.cancel(handle) -- # clear the event listener This example can be modified to control the window of another process as well. I hope this can get you started. Ask away if this isn't very clear....

    Each process in openos has its own instance of a cursor. It's stored in the window property of a process I believe.. try assigning to the processes window cursor as term.setCursor will only set the cursor of the process calling it... I can't test any code ATM so you may have some exploring to do

    Are you trying to move the cursor of another program like 'edit' or something?? I'm a bit lost. Perhaps post all your code

    Are you using term.setCursor??
  14. I'm not super familiar with AE but I think you need an export bus and a robot or drone with an inventory controller
  15. If event.listen is after a continuous loop then it wont be called until that block is finished. To use event.listen it should be called before the loop starts. Note: the loop will have to yield somehow via either event.pull or os.sleep or computer.pullSignal. while (some_condition) do doSomething(data) os.sleep(5) doSomethingElse(more, data) end event.listen('some_event', listener) -- # this will not run until `some_condition` above returns false or there is an error event.listen('some_event', listener) while (some_condition) do doSomething(data) os.sleep(5) -- # if an event named `some_event` happens during this sleep call above then the listener will execute doSomethingElse(more, data) end background stuff.. local thread = require 'thread' local event = require 'event' local bg_proc = thread.create(function() print 'starting background thread..' while true do local ev = event.pull 'key' print 'somebody pressed something!' end end) print 'starting main loop' local i = 0 while true do i = i + 1 print('count is ' .. tostring(i)) os.sleep(1) end
  16. How big is the serialized table and what kind of values are in the table? Are there recursive entries or functions in the table?
  17. Possible. Maybe. But definitely not practical. You would use the network card along with client and host programs on each machine. Computers dont have access to each others components so any communication can be done over a network. You can write a program on one machine to request access and write data over a network connection and another program on another machine to answer requests and read/write data from that connection. Im not really sure of another way to perform this. Perhaps others can chime in.
  18. I don't believe one computer can edit another computers files unless they are connected via some sort of client program over a network which you would have to write. io.write it's for writing to running processes or files in the same machine
  19. I'm having a hard time understanding your question. Can you be more descriptive of want you want to achieve?
  20. So there are two ways to do this. The first is a little more complex. You can simply have two screens and one gpu and switch which screen the gpu is bound to and draw. The second and probably better way is to have two gpus, one for each screen. -- # 2 screens 1 gpu local component = require "component" local prim_screen = component.gpu.getScreen() local sec_screen -- # get the second(non primary or unbound) screen address from the dev fs local f = assert(io.open "/dev/components/by-type/screen/1/address") sec_screen = f:read "*a" -- # read the file which has the component address f:close() -- # clean your room -- # the goods print "this is one screen 1" compnent.gpu.bind(sec_screen) print "gpu is bound to screen 2 now" component.gpu.bind(prim_screen) print "back to screen 1" -- # 2 gpus local component = require "component" local gpu1 = component.gpu local gpu2_address, scr2_address for address, ctype in component.list() do if ctype == 'gpu' and address ~= gpu1.address then gpu2_address = address elseif ctype == 'screen' and address ~= gpu1.getScreen() then scr2_address = address end if gpu2_address and scr2_address then break end -- # quit early if we have the second gpu & screen pair end local gpu2 = component.proxy(gpu2_address) gpu2.bind(scr2_address) -- # bind the second screen to the second gpu gpu1.set(3, 3, "this is on screen 1") gpu2.set(3, 3, "this is on screen 2") Hope this gets you started. Feel free to ask more if you like
  21. I'm afraid it's not possible. The max screen resolution is 160x50. But you could use multiple screens for extra real estate
  22. local GUI = require("GUI") local component = require 'component' local thread = require 'thread' local event = require 'event' local reactor = component.reactor_chamber local currentTemps = reactor.getHeat() -------------------------------------------------------------------------------- -- Create new application local application = GUI.application() -- Add panel that fits application application:addChild(GUI.panel(1, 1, application.width, application.height, 0x262626)) -- Add smaller panels application:addChild(GUI.panel(4, 2, 23, 4, 0x880000)) application:addChild(GUI.text(5, 3, 0xFFFFFF, "Current Reactor Temps")) -- Grab a reference to the text object you need to update local gui_temp = GUI.text(5, 5, 0xFFFFFF, currentTemps) application:addChild(gui_temp) application:draw(true) -- initial paint thread.create(application.start, application) -- Start the app event handler as a subprocess of this one while true do os.sleep(3) -- Update the element every 3 seconds gui_temp.text = tostring(reactor.getHeat()) gui_temp:update() -- Signal the app that this element should be refreshed end This is just another attempt in case I missed something... If this doesn't work yet again, then could you run `cat /tmp/event.log` after running this (if it fails), and reply with its output if it's available. Threads and event timers don't throw errors in the main process.
  23. 1) yes. The quotes. 2) autorun isn't depricated ( I don't think..) but you might like the .shrc format better. Run 'edit .shrc' in the home dir and add the path to the file you want to run on the first available line. It's super simple and can have multiple programs to run on startup. Also programs can take shell args just like typing it in yourself.
