More on text editors that are used with RoR and we not discuss VIM or Vi Improved. Vim like Emacs is quite efficient and easy to use with RoR provided it is set-up properly. The nice about Vim is that it has the nifty way of highlighting syntax in ruby making it easy to trace and debug. It features advanced features such as having a selective command and insert mode with the first being the default mode upon startup. It is not a word processor so fonts and other word processor features are not to be expected.
TextPad
One of the quickest and easiest to use as a text editor for making RoR programs with straightforward interface and features mostly adept to windows users. Though considered a text editor it is capable of syntax highlighting, search , spell check and macro recording which makes it a choice of many developers.
ArachnoRuby
Is deployable on both windows based and Unix based systems and is considered to be the native editor of RoR. It was not too user friendly so it quickly lost favor of many developers who turned to the other specified editors for programming code.
