For our study groups we recommend using Sublime Textas a text editor, which you can download and run on Mac OSX, Ubuntu, orWindows. This is an editor that has been specifically designed for writingcode, comes with a lot of great tools, and can be easily customized.
Other text editors that might be worth looking at are Atom, Textmate 2, and, ifyou like to use some of the powerful oldschool tools from the early times ofUnix, VIM and Emacs. These are all great editors to use.
Whatever editor you use, you want it to insert 2 spaces when you hit the “tab”key, i.e. when you want to indent your code. Make sure your editor isconfigured to do this.
- Most successful Rubyists aren't big users of IDEs in the way that Java developers use Eclipse or.NET Developers use Visual Studio. For a beginner, NetBeans or RubyMine can be a good intro to Ruby, but most serious Rubyists use something more ligh.
- A text editor is at the core of a developer’s toolbox, but it doesn't usually work alone. Work with Git and GitHub directly from Atom with the GitHub package. Create new branches, stage and commit, push and pull, resolve merge conflicts, view pull requests and more—all from within your editor. The GitHub package is already bundled with Atom.
For Sublime Text you can do the following: In the menu item “Sublime Text” goto “Preferences” and select “Settings - User”. This opens up a configurationfile that you can edit just like any other file. Make sure it looks like this:
Also, we recommend enabling auto-saving your files. This will automaticallysave your changes when you switch to another application (like your terminal),and protect you from the mistake of forgetting to save:
Editor doesn't matter so much. Main thing is get something like rbenv installed so you can manage ruby versions. At my work, a few of us use sublime, a couple vim users, a couple textmate users. If you want more of an IDE, rubymine is your best choice. Aptana has support for ruby as well, but i think sublime or textmate is a better choice over.
Whenever you open a new file, make sure to save it with a filename that endswith .rb first. This will tell the editor that you want this to be a Rubyfile. Your editor will start highlighting your code as Ruby code, and enable otherRuby specific editor features. Alternatively, select “Ruby” in the extensionsmenu at the bottom right.
Some keyboard shortcuts that are extremely useful to know are:
- In order to indent or unindent a single, or multiple lines of code, selectthem and hit
taborshift-tabrespectively. - In order to comment single, or multiple lines of code, select them, andhit
cmd-/on Mac OSX, orctrl-/on Linux/Windows. - Cut out code with
cmd-x, copy code withcmd-c, and paste it withcmd-von Mac OSX, on Linux/Windows use thectrlkey instead.

As a passionate PHP developer, and having used competitor products extensively, I appreciate Komodo IDE every day. The improvement it and its add-ons have made to my productivity literally paid for the license cost in the first month. Chrome for mac pro.
Marc Gray, Lamped.co.uk
I appreciate your realistic licensing [for Komodo]—I paid for my own copy and I use it at home on my Linux desktop, on my laptop, and here at my day job.

Komodo is a great product. My favourite feature is the regex generator/tester. It’s saved me heaps of time and aggravation when coming up with complicated regular expressions to get through weblogs and the like.
Ben Maddock, Web Administrator (UniSAnet), Flexible Learning Centre, University of South Australia
The increase in productivity I got from the interactive debugging environment in Komodo IDE probably saved me more than the purchase price within 48 hours. This is a quality product.
