Following are some of the IDEs commonly used in Windows for Ruby programming. I prefer Aptana Studio 3 for writing Ruby programs in Windows. It has all the cool features you require when you write Ruby programs,It is free! Supports syntax highlighting Integrated Ruby debugger! Code assist and auto completion Code outline (classes, modules and methods) Installing Aptana Studio as Ruby IDE in Windows. Download the standalone Windows installer for Aptana Studio 3 from this link. If you already have Eclipse 3. Aptana plugin to enable Ruby support in Eclipse. However I prefer the standalone version. The download is about 1. MB. Double click on the downloaded installer. Select a destination folder for Aptana Studio and click on Next. Choose defaults for the start menu options in the next screen and click on Next. Select file associations in the screen and click on Next and then click on Install to complete the installation. Installation may take a while since a large number of files are extracted. Aptana Studio requires a Git version control system installation on your system for its scripting features. Thankfully it can also install a private copy of Portable. Git for this purpose. When you start Aptana for the first time, you will be presented with the following screen. Click on "Use Portable. Git" button. Aptana uses the concept of workspaces (from Eclipse) which by default is the location for all the projects you create. You can create the default workspace location from the menu, File => Workspaces => Other. If you select another workspace, you will need to configure Portable. Git again. Also the workspace folder by default takes over 1. MB of hard disk space including Portable. Git! To develop a Ruby program, Click on File => New => Ruby Project option from Aptana Studio. Let us create a simple Hello World program. We will create a project and then add our program to this project. Enter the name of the project as "helloworld" and click on Finish. An empty project will be created in the workspace. From the App explorer or the Project explorer, right click and click on New => File. Type in the name of the file as helloworld. Finish. Now you have an empty Ruby program in your project. Open helloworld. rb and type in the following program. Save helloworld. rb and from Aptana menu, click on Run helloworld. You will see the output of the program in the console window of Aptana. However if you try to debug the program from Aptana, you will get the following error,Unable to find ‘rdebug- ide’ binary script. May need to install ‘ruby- debug- ide’ gem, or may need to add your gem executable directory to your PATH (check location via ‘gem environment’). In order to debug Ruby programs Aptana requires the ruby- debug- ide gem. Ideally this should be a simple step, but as of writing this blog post, installing it requires a bit of effort. Enabling Ruby Debugging Support in Aptana Studio 3. In order to debug Ruby programs in Aptana, the ruby- debug- ide gem is required. Installing the gem is a simple step. Run the following command from the command line (requires an active internet connection),gem install ruby- debug- ide - -platform=ruby. However this throws up the following error,C: \jjc\tools\Ruby. Fetching: ruby- debug- ide- 0. ERROR: Error installing ruby- debug- ide: The ‘ruby- debug- ide’ native gem requires installed build tools. Please update your PATH to include build tools or download the Dev. Kit from ‘http: //rubyinstaller. Development- Kit’This means that I need to install Ruby development kit. This kit is required if you want to build native Ruby. Gems from the source code. Download the Dev. Kit compressed file from the Rubyinstaller download page. I downloaded Dev. Kit- tdm- 3. 2- 4. MB+ ). This is a 7zip self extracting archive. Run the program and choose a directory where you want Dev. Kit to be installed. I keep it as a subfolder under the Ruby folder. Open a windows command prompt and change the directory to the Dev. Kit folder. Type the following command to configure Dev. Kit installation. This command will identify the Ruby installed by Ruby. Installer as shown below. Now run the following command to enable Dev. Kit for the Ruby installations in your machine. For more details on the Dev. Kit installation, check this page. Now try installing the ruby- debug- ide gem from the command line. Note: this step took a couple of minutes in my machine)gem install ruby- debug- ide - -platform=ruby. What I got is another set of errors (see below)! The problem is that the latest release version of ruby- debug- ide (4. Ruby 1. 9. x. Temporarily enhancing PATH to include Dev. Kit… Building native extensions. This could take a while… ERROR: Error installing ruby- debug- ide: ERROR: Failed to build gem native extension. C: /jjc/tools/Ruby. Building native extensions. This could take a while… Building native extensions. This could take a while…Gem files will remain installed in C: /jjc/tools/Ruby. Results logged to C: /jjc/tools/Ruby. This bug is already fixed in the latest source code of ruby- debug- ide. However it is not yet a release version. So we need to tell the gem tool to download and install the latest pre release version by passing the –pre command line switch. This installs latest pre release version of ruby- debug- ide (version 0. This will enable the debugging feature in Aptana Studio. Check the debugging feature by setting a break point on your program and then clicking on the debug icon. Now you are all set for developing Ruby programs in Windows!
