Hello all, I am a Java programmer and I started today with Ruby and also RoR. I am using the RadRails IDE (is that the best?) and I would like to know if there is a auto-completation feature like in Eclipse for JAVA (ctrl + space for classes and methods). Do I need to install anything else? I am still learning the language’s sintax and I am loving it. It is so intuitive and agile. Thank you. ---

Do I need to install anything else? Netbeans 6.0 has an auto completer, per other threads here. > I am still learning the language’s sintax and I am loving it. It is so > intuitive and agile. Eclipses’s autocompleter for Java is so good it makes you wonder - if the editor can do everything, then what is the there language for? Much of that autocompleting was simply “filling out forms to request permission to do something”. Ruby only needs like 10% of the source lines of Java, so you will find yourself completing less and thinking more. To get a snapshot of what’s available, add this temporarily: p myObject.public\_methods.sort The next problem with autocompletion is Java is static and Ruby is dynamic. That means, in Java, you can determine the type of any object without running the program. That’s what the autocompleter does. Ruby saves lines by using a leaner system. You _can’t_ tell the type of any object before running the program. So an autocompleter would need to either guess or run the program. If I were inventing an autocompleter, I would attach it to the test system. (You _are_ using the unit tests, aren’t you?) Then at complete time, I would fetch the type of each object from a log of the execution of the tests. Unit tests are part of the system that makes dynamic typing more productive and robust than static typing. – Phlip [http://c2.com/cgi/wiki?ZeekLand](http://c2.com/cgi/wiki?ZeekLand) ← NOT a blog!! ---

unfortunately RadRails doensn’t support this feature. i’m missing it too. but it depends on RDT, not on RadRails. if the guys implement this into RDT, it will be available soon in RadRails. don’t know if it’s available with the next version. but i think not. but radrails development moved to the great aptana guys. so i thnk we can expect some new shiny features in the future. another great upcoming rails IDE is netbeans. they support intelli sense! but it’s still beta. but looks very, very promising. so you should give this a try too. here are some screencasts on whats going on: [http://blogs.sun.com/roumen/entry/two\_demos\_jruby\_on\_rails](http://blogs.sun.com/roumen/entry/two_demos_jruby_on_rails) another tool is ruby in steel. it’s an plug in for visual studio. intelli sense on board too. only in the “pro” version afaik. [http://www.sapphiresteel.com/](http://www.sapphiresteel.com/) don’t ask if it’s the best in here. 😉 only thing you’ll hear is the mac with Textmate is the best. it’s a kinf of religion. what platform you are using? windows? linux? mac? i’m using RadRails for my daily work on windows. i’m quite happy with it. one point that’s always find fault is the memory consumption. but who cares. memory is cheap. 😉 if you are using a pII with 128meg radrails isn’t the best choice for you. 😉 but if you’re a java developer, i think your box is strong enough.

Ruby is really nice. I took me a while to get familiar with it. but now i really like it. i think 512mb is a bit less. my memory consumption reaches over day peaks of 1,3 - 1,5 gig. but to be fair, RadRails “only” uses 120 - 140 mb on average. ruby console goes with rdebug up to 100 mb over the day. firefox and IE do the largest amount of the rest. i’m using XP too. no problems here. so, buy memory and enjoy developing with rails. 🙂 On 9 Mrz., 17:06, “Leonardoalmeidabastos” ---

I’m not sure but it may be written by the guys behind Ruby in Steel (Sapphire Steel). Cheers Mohit. ---

Thank you for the update. I’m using Windows XP right now but I also have Debian Ubuntu Linux. I dont know which is the best for Ruby. I’ll try it on linux later 🙂 I have 512mb of ram and I hope that it is enough (it is for Java). I’ll spend a few days learning Ruby before I dive into Rails. I enjoy the fact that Ruby is 100% OO. \o/ ----- Original Message ----- From: “dweinand” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) To: “Ruby on Rails: Talk” [removed\_email\_address@domain.invalid](mailto:removed_email_address@domain.invalid) Sent: Friday, March 09, 2007 12:50 PM Subject: [Rails] Re: Hello RoR
