Nightcode app mexico6/7/2023 You can put anything in between the quotes where Hello, World! is now. Lastly, go back up to core.clj and change what the -main function is going to print. This indicates that any instructions you type in here will be executed within this namespace. Instead of saying user=> like the prompt in the left pane, this should say re=>. Some instruction text will scroll by, and then you'll see a prompt. It may take a few seconds to run after you click it. You should see Hello, World! appear and then the text = Finished =, which is just there to let you know the program's done. In this panel, you'll see buttons for running your project, as well as "Run with REPL." Try "Run" first. Look at the command panel, at the bottom right, highlighted in this screenshot. Let's look at one more thing you need to know. We're not going to change this for now: that's something to do as you're learning Clojure, which you should be able to do now that you know how to start a project in Nightcode. Right now, this file just has one function, -main, that will print out the text Hello, World!. You should see core.clj, which you can click to see the contents of the file. Click the plus sign next to src and then the one that appears next to my_clojure_project. Once you've done that, the left pane will change to show you a list of all the files in your project. As you can see, you have many options, including Java and ClojureScript projects, but for this first one, choose "Console - Clojure" and click "Create Project." Above the "Create Project" button is a text field for entering the Clojure namespace you want created for your project by default: leave that be for now. This one asks what type of project you want to create. Use the file dialog box to navigate to where you want to create your project and type my-clojure-project into the text box beside "File Name," like in this screenshot.Īfter that, click the "Save" button and you will see another dialog. When you are ready to try making a Clojure project, click the "New Project" button at the top left. If your window looks like the following, minus the arrows and green text, you are in business. Click to the right of the prompt and enter (+ 1 1). This area is called the REPL, which stands for "Read-Eval-Print-Loop," or in English, the place where you interact with Clojure. Look at the bottom left of the window where you should see the current version of Clojure and a prompt that says user=>. If not, open a terminal and run the following commands:Īfter this, you should see a Nightcode window like the one below. If you are on a Mac or using a graphical file browser on any operating system, you should be able to double-click it. Go into your Downloads folder (or wherever you save files from your browser) and run the nightcode-x.y.z-standalone.jar file. If you are using Linux, you probably know how to install it, and if not, look at your distribution's documentation.Ī file called nightcode-x.y.z-standalone.jar will be downloaded, where x.y.z is a version number. ![]() You will need Java installed: if you are using a Mac, you have it installed. To use it, first go to the Nightcode site and download the most current version. It bundles everything you need to use Clojure so you can get started quickly. ![]() ![]() Nightcode is an easy-to-use IDE for Clojure written by Zack Oakes. Emacs and Vim are good choices for Clojure editors, but they aren't for everybody and they can be complicated to set up. While using Clojure everyday is a blast, getting started with Clojure isn't always. Getting Started with Clojure using Nightcode
