Today I present coder an IDE for us, Netbeans!
Well, I have used this for 4 years, of course not to code Ruby/RGSS (In fact, I learnt PHP :D), and I really love it. Why? First of all, It’s free. And second, Its size is not large (compare to Eclipse) and it’s more convenient than Notepad++. Thirdly, This is an optional, You can install more plugin and support more languages!
I won’t tell you about the features, because I’m lazy because you can read it here.
However, You cannot test with Netbeans, it should be a waste of time if you made a small script with IDE, but If you are making a big script (like a battle system), using an IDE like Netbeans will help you a lot.
Talk enough. I’m going back to work now ahaha ~
