No matter – you will now need to edit text. You may remember the days when computers had text-based interfaces, or you may have only pushed buttons and tapped icons until now. It lets you get under the hood and really see what’s going on. In Raspbian, which is based on Debian Linux, you are far more likely to need to edit text files than on computers running MacOS or Windows. Every menu, every button, and every setting of every program started as a text document somewhere. A secret that most computer makers don’t tell you is that underneath all the gloss and shine of modern operating systems, it’s all text. It's all part of learning how computers really work. PLAIN TEXT EDITOR RASPBERIAN HOW TOAfter writing text or introducing change to the file, the title bar will show Modified at the top right side.Learning how to edit text files in the console and from the Raspbian GUI is a rite of passage for new Raspberry Pi owners. Figure 9: Cut and Paste in Nanoįurthermore, a new and unnamed file will display new buffer on the title bar. Using these, you can already get the text in and out of Nano. This will bring out the usual copy-cut-paste options you see on standard word editors. In order to do that, you must press the Shift and Right Click button. PLAIN TEXT EDITOR RASPBERIAN SOFTWARECutting and pasting using Nano shortcuts won’t let you get the text out of Nano to another software and vice versa. If you want to cut a selected text, simply type CTRL + K. So for example, if you need help, just type CTRL + G. The carets on the shortcuts stand for the CTRL button. You just type text directly and you always see the keyboard shortcuts under. You can just start nano by entering the nano command. PLAIN TEXT EDITOR RASPBERIAN INSTALLNano comes with Raspbian as a default editor so you don’t need to install it explicitly. It’s easy to use and offers a myriad of keyboard shortcuts, which are useful when writing in a computer’s CLI (Command Line Interface). GNU Nano is the native text editor of most Linux distros. PLAIN TEXT EDITOR RASPBERIAN CODEFigure 6: Error HighlightingĪdditionally, you can click Check to search for errors on your code without running the program. Mu checks for errors and highlights them in red so you can detect coding mistakes without a problem. One useful feature of Mu is error highlighting. You will see the output on an integrated Python shell below the text editor. py on the file name as Mu already assumes the file type when you set the mode to Python 3. Let us now write the canonical Hello World program. For now, we are going to use it for Python programming. You can change them depending on what you intend to use Mu for. ![]() ![]() The current version of Mu offers 4 modes. One is by accessing Menu on the top left side of your desktop. There are two ways you can get Mu in your system. Installing Muīefore you install Mu in your Raspberry Pi, make sure your Raspbian OS is up to date by entering sudo apt-get update and sudo apt-get dis-upgrade in the terminal. It is known for being easy-to-use as its target users are beginner users. Mu is a text editor and IDE (Integrated Development Environment) specially made for Python programming. In this tutorial, we are only going to explore 1 of each kind: Mu for the desktop graphical editors and Nano for the command-line editors. Some of the command-line editors you can use on a Raspberry Pi are: They use keyboard shortcuts as an alternative to a point-and-click interface. Unlike desktop graphical editors, command-line editors can be used with only a keyboard. Some of the desktop graphical editors that you can use on a Raspberry Pi are::Ĭommand-line editors, on the other hand, can only be accessed using the Terminal. Moreover, to use a desktop graphical editor properly, you need to have a mouse and keyboard. ![]() You can access them through the Raspberry Pi Menu or the Terminal. Desktop graphical editors are text editors that have a GUI (Graphical User Interface). ![]()
