Method auto-completion for the core Ruby types will be in the next
release of the Ruby Editor Plugin for jEdit, hopefully out in the next
week. A documentation window will show next to the method list popup,
so this will be a great tool for those new to Ruby. Alex, Ruby Editor
Plugin pentru jEdit e cel mai bun*!

What's missing from the Ruby IDE space is an editor let's you
manipulate Ruby at the syntax level. For Java, modern IDEs let me
think in terms like "method complete", "find declaration", "find
usages", "extract variable", "rename member", "extract method",
"change method signature", "go to last edit", "go to last location",
etc. jEdit's Ruby Editor Plugin is evolving into this style of IDE.

Not having to think about the more low-level textual manipulations
frees your mind to make syntactical ones; obviously important in a
verbose language like Java, but also of value to large-scale Ruby
development projects.

Cheers,
Rob
