h2. Ruby/Rails IDE

RubyMine 1.0 seems to be really cool

Set the keymap to Textmate if you are used to that
It shows database.yml by default

Command+T works just like in TextMate
Command+B takes you to the definition

Alternate layouts: Rails view is really cool

Command+J shows all the autocomplete fields
Ctrl+Space will autocomplate intelligently
Ctrl+H to bring up documentation really quickly

It knows the database fields

Very nice CSS interaction, it knows about CSS classes

Great version control integration, works very well with Git

Autogenerates model dependency diagram

It's awesome, they have gotten a lot of things right

If you are running a Ruby user group, you can get free copies of the idea for your speakers
