Mac's have TextMate as there preferred application for ruby development, but what would be the preferred application for linux? I need something where it's easy to work with multiple files, project structure and setup commands to run my ruby app or if it is one my merb app.Syntax highlighting is also a must.
Now I typically use Vim, but it's not the best for working with multiple files or with a project structure, even with VTreeView plug-in or multiple VIM windows.
So what would you guys suggest?
If you have better plugins to use for VIM feel free to mention them, I'm not ruling out VIM here.
If you are on Ubuntu/Debian, plain old emacs with ruby-elisp package isn't bad. It's no TextMate, but it's not bad.
I prefer Aptana/RadRails on both Mac and Linux. It gives a consistent experience for me no matter what OS I'm on.
I still don't get the excitement over Textmate...
Why don't you just use Sublime Text 2 Text Editor, it is free and cross platform and lighter than any IDE, and then you can install the SublimeCodeIntel which will provide you with autocomplete features , you can do that through installing Package Control , then
It is working perfectly with me and I'm totally in love with this smart editor .
You can find this helpful somehow if you wanna give it a try , http://www.rockettheme.com/magazine/1319-using-sublime-text-2-for-development
I'm using it with zsh Terminal http://stevelosh.com/blog/2010/02/my-extravagant-zsh-prompt/
Anyways if you are looking for a full IDE give netbeans a try http://netbeans.org/projects/ruby/
RubyMine from JetBrains.com works well for Mac/Linux/Windows, the price is 99$ but it's probably the most productive IDE for Ruby and Rails I have tested so far.
Aptana Studio is indeed very nice. Also Gedit does the job if you don't want a full IDE environment and are more inclined to do stuff by hand :).
Setup Gedit to be almost like Textmate
