Subject: [ANNOUNCE] Practical Ruby 0.1.0

    Hi all,

    I'm glad to announce the first release of Practical Ruby
(http://gaiacrtn.free.fr/), an IDE for Ruby on the Windows platform. It is a
'proof of concept' release. I got that crazy idea last Monday and finally
implemented enough to know that it can be done:

    Practical Ruby aims to be a fast evolving IDE for Ruby development. To
provide fast evolution, most of Practical Ruby is (will be) itself written
in Ruby.

    The source editor is build around Scintilla Edit Control
(http://www.scintilla.org/), a very flexible source edit control. While the
GUI core is written using MFC, most of the tasks are delegated to Ruby
scripts. The Scintilla Edit Control has been made accessible from Ruby, with
an interface making the control much easier to use than in C++. Commands
(menu entry selection, toolbar button and keyboard shortcut) processing is
also delegated to Ruby.

    Feedback are welcome! I would really like somebody to propose a
architecture for the command pattern in MainFrame.rb using ruby features (I
started learning ruby less than a week ago, I'm sure there is a better way
of implementing that with ruby's features).

    Just to give you an idea why ruby help faster development, I'll let a
bit of code talks for itself. Here is the code that handle the 'smart
indent' (basic at the current time):


class EditControl < ScintillaBridge
    def eventCharAdded( ch )
        smartIndent() if ch == "\r"  ||  ch == "\n"
    end

    def smartIndent()
         if currentLineNumber() > 0  &&  lineLength( currentLineNumber() )
<= 2      # 2 <= '\r\n'
            previousLine = getLine( currentLineNumber() -1 )
           indent = /^\s*/.match( previousLine )[0]
           replaceSel( indent )
        end
    end
end

Enjoy,
Baptiste Lepilleur.
