MineOS is half the operating system and half the graphical environment for OpenOS, which comes in OpenComputers mod by default. Oringinally it was developed in Russian, but it supports several languages. MineOS has following features: Multitasking Windowed interface with double buffered graphics context Animations, wallpapers, screensavers and color schemes Language packs and software localization User authorization by password and biometrics Support for file sharing over the local network via modems Support for client connection to real FTP servers Error reporting system with the possibility to send information to developers App Market with enormous amount of wonderful applications and possibility to publish your own programs for every MineOS user An internal IDE with syntax highlighting and debugger Open source system API and detailed illustrated documentations Custom EEPROM firmware with the possibility to select/format the boot volume and Internet recovery Almost complete compatibility with OpenOS software How to install? First, you need to install OpenOS from floppy disk to your HDD. After that you'll be able to run MineOS installer via single command: pastebin run 0nm5b1ju System requirements: Internet Card OpenOS installed on Tier 3 HDD Tier 3 GPU 2x Tier 3 RAM Tier 3 CPU (not really matters, just speed up) Troubleshooting: Are there any problems, suggestions? I'll be glad to see you on the operating system repository: https://github.com/IgorTimofeev/MineOS

No spoiler in the title. Just watch the video.

The sound card is added by Computronics, a wonderful addon for OpenComputers. There are a few who actually know what it does. Even less people are able to use it. No one dares to understand how it works, or so I hope. Anyway, it appeared a few years (?) ago, and is still mostly undocumented. There is a page in the in-game manual, which fails to explain how great the card is. Of course it does! It has a heap of different methods, which you can use to cast many crazy magics to make the sound card sound, and it's impossible to teach someone to do magic by reading a single page. OK, I'm serious now. Last year I managed to understand how to use it, and even wrote a few posts about that. In Russian. Half a year later, I translated them to English. And now I thought of posting a topic here so that you could read them, too. Here's the link. The first two parts are all about basic things, like getting simple sounds, ADSR, and modulation. The third part features a little bit more complex things, like complex numbers and Fourier transforms. I tried to keep it simple, so I could get something wrong. If so, please leave a comment there pointing out the mistake. Grammar fixes are also highly appeciated.

I decided to make an editor with syntax highlighting, just for the fun of it. The name stands for "syntax highlighting editor", it's very unoriginal, but I'm bad at names To use it, run this command on OpenOS: pastebin get ZnwyunqL /bin/shedit.lua The color scheme was (sorta, I redid it later) copied from this paste. Features: Syntax highlighting! Indent on enter Line numbers Jump to line Hex colors are highlighted with the color they refer to (example: ) And probably more in the future if I need them.. Screenshot: Any recommendations or comments are appreciated!

Hi everyone. A while back I promised more releases, so here you go: Big Reactors Grid Control is a multi reactor/turbine controller for Big Reactors and Extreme Reactors. Mission goal: Be the best big reactors controller there is. Nothing more, nothing less. First things first - here's the website: https://tenyx.de/brgc/ Main features Active and passive reactor support Support for multiple reactors and turbines at the same time (n:m) Control active and passive reactors with the same controller Automatic configuration of everything (EVERYTHING!) Setup instructions wget the installer from here: http://xypm.tenyx.de/standalone/brgc_installer.lua Run it Done Big Reactors Grid Control comes with three rc.d files: /etc/rc.d/brgc_reactor.lua /etc/rc.d/brgc_turbine.lua /etc/rc.d/brgc_grid.lua If you want the controller to run at boot time, you can just use OpenOS' rc.d schema. There's a GUI as well as a command line utility for advanced users. To start the gui, simply run "brgc_gui" and watch the magic happen. The gui scales the screen resolution to match the screens ratio and should scale with basically all screen setups. I recommend 3x2 or 4x3 screens. As of now the command line utility allows you to do (almost) everything you can do with the GUI and also allows you to change the controllers configuration at runtime (if you so desire). Check out "brgcctrl help" for further information. How to set up the grid In a basic setup you just interconnect everything: All active reactors can output steam to all turbines. All passive reactors and turbines output energy to the same grid. You CAN have passive reactors and turbines output energy to different energy grids. While this poses absolutely NO problem for passive reactors, you will have to set some turbines to "independent"-mode (more on that below). If you want your reactors and turbines to properly cooperate, you'll also need to connect at least one energy storage block to your energy grid. Currently supported storage "blocks" are: EnderIO Capacitors (requires the mod "Computronics") Draconic Evolution Energy Storage multiblocks. RFTools Energy Cells Thermal Expansion Energy Cells Mekanism Induction Matrices You can connect them using OpenComputers Adapters. Discovering new components As mentioned before the controller tries to autoconfigure everything: Passive Reactors When a new passive reactor is connected to the controller, the controller will first try to measure its maximum energy output. The reactor will have its output increased step by step and the average (interpolated) maximum will be used for that value (CALIBRATING). After calibration has been completed, the controller calculates the most efficient energy output of the reactor. Active Reactors When a new active reactor is connected to the controller, the controller will first try to measure its maximum steam output (CALIBRATING). For this to work correctly the reactor must be able to output at least SOME steam (read: you need a consumer) and you will need to provide sufficient ammounts of water. The controller will detect reactors with a potential steam output greater than 50 B/t and limit its energy accordingly. Turbines When a new turbine is connected to the controller, the controller will first try to measure its maximum energy output (CALIBRATING). For this to work, make sure your turbine is built correctly. This means your turbine can be run at maximum supported steam (25mb/t per blade) without exceeding 1950 RPM. Should your turbine exceed 1950 RPM at any stage, the controller will shut down the turbine and flag it as failed. Note: Your turbine is NOT required to be able to process 2000 mB/t. Smaller turbines work perfectly fine. Screenshots After this wall of text, here're some screenshots (pre 4.2). Setup: Main view: Passive reactor details: Active reactor details: Turbine details: Let's go in order: When you start up the GUI you will be presented with the main view. Here a combined overview of passive reactors, active reactors and turbines will be presented. You can click (or touch) on any of these items to open up a detailed view of the component. Here you can enable/disable the component or change its behaviour. What behaviour? This is where it gets interesting. Passive Reactors You will notice that passive reactors have two modes and an "auto" mode. PWM This is the behaviour everyone knows: The reactor gets turned on when its internal energy storage drops below 10% and gets turned off when the energy storage exceeds 90% of it's maximum capacity. In PWM mode the reactor will generate energy at its most efficient rod level. Overall this mode allows the reactor to generate energy as efficiently as possible as long as your actual energy consumption is below or equal to its optimal energy output. But sometimes you need just a bit more energy and you don't want to upgrade your reactor or build a new one. "Classic" controllers will fail to produce sufficient ammounts of energy here. This leads me to the second behaviour: Load In "Load"-mode the reactor will always aim to produce energy at the same rate as it's consumed. Maybe some people already suspect what that mode is all about: It's a PD-like regulator. While "Load"-mode is not as efficient as PWM-mode in situations where the energy consumption is below the optimal energy output, it will guarantee you're never running into energy shortages - provided you're not exceeding the reactors maximal capacity. Auto "Auto"-mode aims to eliminate the disadvantages of both modes by combining them: If the energy consumption can be satisfied with PWM-mode, PWM will be used. If the energy consumption is above optimal levels, "Load"-mode will be used instead. As a result, "auto"-mode generates energy as efficient as possible while always saturating your energy demands. Active Reactors As of now, active reactors only operate in "load" mode. Steam is consumed and produced way too fast and the reactors internal steam storage does not allow for anything else. Turbines Turbines controlled similar to reactors in "load" mode: The controller will always try to balance the turbines internal energy storage out to 50% by using a PD-like regulator. Turbines can be operated in "ganged"-mode or in "independent"-mode, with "ganged"-mode being the default. The only difference between these two modes is that turbines in "ganged"-mode can be shut down by the controller, while "independent" turbines will always be active, even if they overproduce energy at the lowest RPM allowed. This is handy if one (or more) of your turbines produces energy for a seperate (dedicated) energy grid but has to be controlled by the same controller. If such a turbine is not in "independent"-mode it may be shut down which will lead to energy failure in that grid. That's it for now. If you have any questions, want to report bugs, etc., feel free to drop a message here. Also: Do you want an indepth tutorial on how to use the command line utility? Need a description on what the GUI is actually showing? Have fun XyFreak

This is an object-oriented library, the main priority of which is the maximum possible performance. It works on the double buffering concept, it has a lot of widgets, animations and custom event handlers support. All programs from the screenshots above are implemented with its help. If you want to develop a fast and beautiful program in just a few lines of code without butthurt - then this library is made for you. Detailed illustrated documentation, installation methods and tons of practical examples are available at: https://github.com/IgorTimofeev/GUI

This is a simple door opening script that requires a password to be entered. That being said it took me a ridiculously long time to work out all the bugs. It works by taking an input from one computer and sending it to another to check if the password is correct. This makes it much harder to simply look at the file to check what the password is. It also now has the ability to automatically encrypt your password if you have a T1 data card along with the server asking you to input a password on the first run. These ideas came from the user RandomRedMage Requirements: At least 2 computers with basic parts 2 Network cards or Wireless Network cards Redstone T1 card Data card T1 (optional) The pastebin id for the server version is 8Y2y9xH3 The pastebin id for the client version is F5P5V05P Source code for both here Currently it needs to be placed into /home/bin and named door.lua to work but editing the 4 spots where os.execute is called will let you place it wherever with any name Also you need to enter the password twice the first time it is booted in order to have both computers recognize each other this can be circumvented via hard coding the address of the modem of each system into the other or adding a file into each /home/bin called MAC.psd with the modem address of the other. It is currently set up for only one computer but it could easily made to work for multiple by making the address var into a table and having a loop check thru them though that may slowdown the process.

Hi, I've just posted and updated version of ER on Curse (It's under review right now). All the Callbacks are back to the old-direct-call-we-dont-care-about-threads-because-who-knows way of the original code. You must break and replace all your computer ports to see this in action Z

Read, "where the call takes at least one server tick" Here: https://github.com/MightyPirates/OpenComputers/blob/f5c19e9e7e0006d3403c7bf0b44dfb970cee8a2f/src/main/java/li/cil/oc/api/machine/Callback.java#L43-L59

Hello! I'm trying to create a program that can know what is being crafted in the ME network. I want to implement this: when you submit a crafting task in the ME terminal, the computer get notified about it and control machines to finish the task. I've read the code in package li.cil.oc.intergration.appeng but seemed to find nothing related. I'll be glad if someone could help me.

Hello. So you know how to make a program in ComputerCraft and you want to switch to OpenComputers or just want to know OC better, this tutorial shows you how to use OpenComputers. 0. Some concepts you have to know You can think of Components like Peripherals in CC. They are basically the same require is a function in Lua that returns a module. It can be compared to ComputerCrafts os.loadAPI. But require doen't load an API global like loadAPI, instead it returns the API and it doesn't return the _G table that the api defines. It returns what the loaded File returns like a function. More examples to that later in that Tutorial A computer from OC has no OS and no BIOS. So a computer can't start or load something without an Lua EEPROM and a typical OS, with a fancy Text terminal and some programs, is also not available without installing OpenOS first. That makes setting up a OC Computer a bit more complicated but it allows you to make a real OS for your Computer and not just a fancy UI or a Overlay to the predefined Operating System. An Address is used instead of the peripheral name and the ID in ComputerCraft. So your computer won't get the name "computer_0" or the id 0. The Address is a random UUID string and not a number that increments for every computer. So a Address looks more like "cd6c4e39-bbb6-491c-826d-48112912f44d". That can be a problem to remember, but components are usually uniquely identifiable by the first 3 characters of the UUID and later we will learn some other tricks to copy them. You can't shutdown a Computer with Ctrl+S or restart it with Ctrl+R. You have to type "reboot" or "shutdown" in the console or press the green button in the UI for the Computer Case. To interrupt a program in OpenComputers you press Ctrl+C or to forcefully kill it you can press Ctrl+Alt+C. In ComputerCraft you would press Ctrl+T and there is no way to forcefully kill a program in ComputerCraft other than restarting the computer. A Computer doesn't restart when you leave the world or the chunk unloads. Instead they keep the memory and the program running on it won't notice that the computer stopped for a moment. Some features are only available with cards. Like the Internet Card for HTTP and TCP (also Pastebin and Wget), Redstone Card for sending and receiving Redstone signals or a graphics card for connecting to a screen. Memory is limited and the amount you can use is determined by the Memory Items you put into the Case Your computer will use Power (If you didn't disable it in the config). Cases can convert RF and other electricity types into OC's own power system. There is also a Adapter that can convert power faster. Creative Cases generate their own power. 1. How to build a Computer If you play with ComputerCraft you just place one block and done. In OpenComputers however you need more. What you have to craft: ComputerCase .... Better Tier means that you can have more components and also components with better tier. CPU or APU ... The Tier of the CPU determines the amount of components that can be connected to your computer. The APU has the same features like a CPU but it can replace the Graphics Cards. OpenComputers allows you to have different Languages by default Lua 5.3 is selected. You can change that by shift+rightclicking the CPU or APU in your hand. Memory ... The memory determines the amount of RAM your program can use. Graphics Card (if you didn't craft a APU) .... This will determine the resolution and the color your screen can have. A Tier 1 Card can only display black and white (like a basic CC Computer) a Tier 2 can display colors (like an advanced Computer) and Tier 3 can display more colors. Screen ... The screen determines the resolution and color like a graphics card. The setup will only be as good as the weakest part. So if you have a Tier 1 Card and a Tier 2 screen you can't display colors and the resolution will only match a Tier 1 setup. So both GPU and Screen should have the same Tier. A Tier 2 or 3 Screen can also handle touch events like an Advanced Computer from ComputerCraft. Keyboard ... The keyboard doesn't really do anything other than enabling the GUI of the screen to type something. Without a keyboard you can only look at the screen and use it as a touchpad (if you have Tier 2 Screen or higher). Disk Drive ... A disk drive is similar to the disk drive in ComputerCraft. A tier 3 cases and a creative cases have a builtin Disk Drive, so you don't need one if you selected one of these cases. OpenOS Floppy ... This item contains the OpenOS ready for installation. This floppy won't get consumed so you only need one and as long as you don't lose it you never have to craft a new one. Hard Disk Drive ... This allows you to store data. The tier determines the amount of storage you have. (Lua BIOS) EEPROM ... This is the BIOS that loads our OS. It is required for the startup of our computer. If you have crafted one, you can copy the EEPROM by combining the Lua BIOS EEPROM in a crafting Table with an empty one. The setup: As you can see on the first image, the power cable can be connected directly to the case (no need for the adapter in this setup). The keyboard has to be a neighbor of the screen, but it doesn't have the be placed on the screen. So if you want to build a fancy table in from of the screen with the keyboard on top of it, you can do that. The Disk Drive and the screen is placed directly next to the case, you can also place the case somewere else and connect the screen and the drive via a cable, like in ComputerCraft. (except you don't need modems) In the second picture you see, how you have to put the components into the UI of the case. The tier of the component has to be the same or lower than the number shown in the slot. OpenComputers helps you by highlighting possible slots and items in your inventory and also in JEI if you have it installed, you just have to hover over the item to see possible slots or hover over the slot to see possible items. In the second picture you can also see, that items get an address. That would be the address of the component if the items acts as a component. Like a redstone card would give you the redstone component. If you have TOP (The One Probe) or WAILA installed the address of a component is also visible in there. You can see them on Cases, Screens, Redstone IO blocks, ... . If you don't have WAILA or TOP installed you can use an analyser from OpenComputers to get the address. If you hold Ctrl while rightclicking a block with the analyer you can copy the address of that component block. 2. Install OpenOS As I already mentioned, the OS is not preinstalled when you build the Computer. You can write your own OS, but that's not what we want to do here. So now its time to put the OpenOS disk into the Disk Drive. You can open the GUI and put it in the slot or you can shift rightclick the disk drive (doens't work on the integrated disk drive in Tier 3 cases). The disk drive block will show you the inserted disk. If you now start the computer by pressing the green button inside the gui or shift rightclicking the case with an empty hand, the light of the computercase will light up with a green color, and you should hear some floppy noise. You should see something like this if you open the UI of the screen. Sadly we are not done yet. If your try to type in " edit test.lua " you will see the error message "file system is read only", that's because the OpenOS disk doesn't store anything on your computer it is a fixed storage, if you craft an empty floppy you would be able to store files on it. But in our case we already installed a Hard Disk Drive we just have to boot from it. To do that we have to copy OpenOS onto it. To do that you simply type " install ". The program asks you if you want to install OpenOS. Now you have to type " y " and enter to start the process. This will take some time. After it is done the program will ask you if you want to reboot. So you can type "y" again. There shouldn't be much floppy sound and more sound from the hard drive. You can now take the floppy disk out and try " edit test.lua " again. It should now open the text editor. In the text editor you can press Ctrl + S to save and Ctrl + W to exit. 3. Troubleshooting So chapter 2. didn't work and your computer won't turn on. If the green light is on but you don't see anything on your screen. It's likely that the screen is not connected or you forgot the graphics card. If there is only a red blinking light you should see a error message in your chat, if that's not the case build an analyser and shift + rightclick the case. You should see the "Last Error". These error messages should tell you what went wrong. Somtimes you also get a blue screen with an error message. If you see the message "Too many components connected" it can means 2 things. One is that you exceeded the maximum amount of components that are allowed for your CPU Tier or you forgot the CPU. 4. Programming This is not a full Lua tutorial I will show you some basic programs and show you the difference to ComputerCraft. First we have to create the file. Simply type "edit test.lua" to open the editor and yes all lua Programms should end with ".lua". Since I want to work with redstone, I put a tier 1 redstone card in the second slot of my case. Since it is the only redstone component it is also the primary component. The primary component should be the first connected component of a type. In this example the redstone card is a "redstone" component. You will see why this is important in a second. --First thing we have to do is to load the component library. --Some libraries are loaded by default but "component" we have to load manualy --Thats the biggest difference from ComputerCraft, that APIs are not loaded from the beginning. local component = require("component") --OpenComputers defines sides as numbers and not as a string like ComputerCraft --But we don`t want to learn every number for every side so we can load a library that does that for us. local sides = require("sides") --Now we see what primary component means. OpenOS defines the primary component as a variable with the name of the type in component. --So we can access component.redstone and will get the redstone card. Later I will show you how to connect to multiple components of --the same type. local redstone = component.redstone while true do --Set the redstone output to 15 (maximum strength). The first argument defines the side. We use the sides api here to help us out --You can also put 3 instead of sides.front but as I sayed we don`t have to remember every number redstone.setOutput(sides.front, 15) --"os" is a library thats loaded by default. We use the sleep function to sleep for 500 milliseconds os.sleep(0.5) redstone.setOutput(sides.front, 0) os.sleep(0.5) end (Sorry it seems like the coloring is a bit off) INFO: You can paste ingame by pressing your mouseweel in the UI of the OpenComputers screen. This program has no exit condition so the only way to stop it is with Ctrl+Alt+C (or reboot the computer). So how can you load multiple components with the same type? We first have to get the Address. You can copy the address into the clipboard by holding Ctrl while clicking with the analyser on a component block. As I mentioned in most cases the first 3 characters in the address should be enough. Lets do the same thing with with a redstone component. --First thing we have to do is to load the component library. --Some libraries are loaded by default but "component" we have to load manualy --Thats the biggest difference from ComputerCraft, that APIs are not loaded from the beginning. local component = require("component") --OpenComputers defines sides as numbers and not as a string like ComputerCraft --But we don`t want to learn every number for every side so we can load a library that does that for us. local sides = require("sides") --This line now contains 2 functions. The proxy function is the same as peripheral.wrap in ComputerCraft but it needs an address and it doesn't work with --sides. To get the full address out of the 3 Characters we have to search for it. The component api has a builtin function called "get" for this purpose. --If you copy the full address with an analyser you can get rid of the component.get call and give the address directly to to proxy function --You should replace "a37" with the address of your redstone card or redstone IO Block local redstone = component.proxy(component.get("a37")) while true do --Set the redstone output to 15 (maximum strength). The first argument defines the side. We use the sides api here to help us out --You can also put 3 instead of sides.front but as I sayed we don`t have to remember every number redstone.setOutput(sides.front, 15) --"os" is a library thats loaded by default. We use the sleep function to sleep for 500 milliseconds os.sleep(0.5) redstone.setOutput(sides.front, 0) os.sleep(0.5) end You can find more information about the apis here: https://ocdoc.cil.li/api In the section "Standard libraries" you can find the libraries that are loaded by default and you don't have to require them In the section "Custom libraries" you can find the libraries that are offered by OpenOS and you have to call "require" in order to load them More information about the components can be found here: https://ocdoc.cil.li/component Many APIs that are built into ComputerCraft are moved to components in OpenComputers like "HTTP", "Redstone", "Rednet", "Disk", "Fs" (partially), "Turtle" (Robot in OC). Fs and Disk are mostly moved to the "filesystem" component, which allows you to get the empty space, rename the disk and basic File access. The "filesystem" api is a more abstract, which allows you to work with file "objects" and it has some more features. HTTP is the internet component in OpenComputers and it is provided by the internet card. The internet component also allows you to make raw TCP requests. The Rednet API in ComputerCraft is basically another way to access the modem peripheral in CC so you can find it in the modem component from OC, which is available if you add a network card or a wireless network card to your setup. Events work similar to the events from ComputerCraft but they have their own Api in OpenComputers called "event". You can find a list of signals (other name for event) here: https://ocdoc.cil.li/component:signals So lets make a example for a touch event: local event = require("event") while true do --This will wait an infinite amount of time for any event local ev, arg1, arg2, arg3, arg4, arg5 = event.pull() --"interrupted" event is fired when you press Ctrl+C if ev == "interrupted" then return --The "touch" event is fired by the screen and gives us: The Screen Address (1), X & Y - Coordinate (2 & 3), The Mouse Button (4) and the Player (5) elseif ev == "touch" then print("Player " .. arg5 .. " touched screen " .. arg1 .. " at X="..arg2.." Y="..arg3) end end You can also filter for one event / signal or give the "pull" function a timeout. If you want to filter for multiple events you can use event.pullMultiple(). More information here: https://ocdoc.cil.li/api:event If you want to handle Ctrl+Alt+C in your program you have to handle errors thrown by event.pull(). You can do that with pcall() but I won't go into details here (this is a normal lua function, so you can search it online). If you want to handle an unknown amount of return arguments from any lua function you can also do " local ev = { event.pull() } " this will create a array with all the arguments and you can access them with ev[1], ev[2], .... 5. Filesystem OpenComputers OpenOS has a more complex filesystem than the OS from ComputerCraft and it resembles the UNIX filesystem. If you bootup your computer you will start in /home. This is where you should write your own programs and store data. /bin ... Programs installed by OpenOS /lib ... Libraries installed by OpenOS ( This is one of the paths where "require" searches for libraries /usr/bin ... Programms installed by the user. Usually via a package manager like OPPM /usr/lib ... Libraries installed by the user. Usually via a package manager like OPPM /usr/man ... Manual pages for programms. You can type " man <command> " to open them /usr/misc ... Some miscellaneous data for some programms /etc ... Configs for programs. /boot ... Scripts that run during bootup /mnt ... This is where you can access other storage devices like floppy disks. OpenOS will create a directory inside mnt with the first letters taken from the address of the disk /tmp ... Temporary storage. Cleaded after a reboot. /init.lua ... File that gets executed by the BIOS /autorun.lua ... This File doesn't exist after a fresh installation. But you can create it to execute a program after startup. (Like the "startup" file in ComputerCraft) INFO: Not all of these directories exist after you install OpenOS. Some of them are created when they are needed by some program. I hope this tutorial helps you to learn how to use OpenComptuers. Maybe I will make a second part about the differences between a CC Turtle and a OC Robot.

I can't look at the code. Avast is telling me there's a virus on your website.

I just got this error! Am I doing something wrong?

Looking good, neat program! Some advice for dealing with strings: If you want to print some text on your screen and insert some numbers/other variables/returns of functions etc. into that text, instead of writing one part of the text, writing the number, and write the second part of the text you can just concatenate(connect) the different strings and the numbers using the concat operator .. (2 dots), then print it. In other words, combine all the different parts of the text first, and then write it to the screen. This will reduce the number of lines in your code and less screen operations are performed. io.write("string1") io.write("string2") -- # -> string1string2 -- # you get the same result with io.write("string1".."string2") -- # -> string1string2 -- # you can include numbers with io.write("string"..1.."string"..2) -- # -> string1string2 -- # you dont have to use the strings/numbers directly, variables containing strings and numbers work fine as well local s = "string" local num1 = 1 local num2 = 2 io.write(s..num1..s..num2) -- # -> string1string2 -- # one example of your code would be: line 55 - 59 term.write("Energy available/maximum: "..computer.energy().."/"..computer.maxEnergy().."\n") And one question: do you actually want the program to wait before printing a new set of information on the screen or do you just want to let your program yield in order to avoid "too long without yielding errors"?

I'll make it official now. Big Reactors Grid Control Version 4.3.1 has been released! Changelog: - Now using the new ER API (0.4.5.48 and higher). Old API is still supported. - Implemented further mitigations for the "too long without yielding" issues. - Included a hack/workaround for a bug with OpenOS 1.7.1 (and earlier) and Lua 5.3 mode. - Fixed a bug where attempting to format a number as an integer (illegal in Lua 5.3 mode). I'm sorry for abusing some of you as beta testers

The main problem here is that "==" is used to compare two values and it returns true or false: 4 == 4 -> true; 4 == 5 -> false The other thing is that the response is not a string, but an iterator that will return the next line whenever you call it. local internet = require'internet' local url = '...' local response = interent.request(url) if response then for line in response do io.write(line.."\n") end end -- # response is an iterator, each time it's called it returns the next line/chunk, this is then stored in the var "line" -- # then you can use the var and print/write it, store it in a table etc

So a few quick things. First, when you get a problem, please send us a screenshot and logs if possible to make it easier for us to identify your problem. Second, when you're looking at an API in the documentation, be sure to look at the examples that they give as they contain lots of hints! For example, the first snippit.lua in the computer api shows why your program doesn't work. I'll demonstrate a working solution here. Before you can call any methods, you have to assign the computer API to a variable. What they usually do in the documentation is to call the variable 'computer' like so: local computer = require("computer") print(computer.totalMemory()) Because you didn't set the api to a variable first, your program tried to call a variable that doesn't exist and gave up. Should be an easy problem to fix

That's not how Lua works. You need to compare the variable with each value you want to check. e.g. if line == "yes" or line == "y" then You can also use the lower method to make this a bit simpler: if line:lower() == "y" then That can also be written as follows: if string.lower(line) == "y" then You probably should read the Lua Manual. Just select the version that the CPU your computer has is using (Either 5.2 or 5.3. Hover over it to see).

@Aquila_chrysaetos thanks for letting me know! It looks like i screwed up the links.... wow.. this must've been broken for a LOOOOONG time. Everything is back up and in order now

@Arcanox I read the update, but besides that, if you sometime find yourself with a bugged brgc setup, I reinstalled the hdd, it solved all of the issues for me. It seems like OpenOS is not a Windows, but some solutions just works on that too :-)

That's my fault.. I could have sworn I approved this post when it was posted, and it was sitting in my queue as seen. I noticed it when I went back and read a few pages of the thread.

For now I will quote Negi, I'll write something proper here later
