[Instantrails-users] Instarails with existing Ruby installation

I guess I wasn't specific enough.  I was following the tutorial at

http://www.onlamp.com/pub/a/onlamp/2006/12/14/revisiting-ruby-on-rails-r
evisited.html?page=2#generate

 

I'm going to use source control, so my App directory structure looks
like this:

C:\App

            branches

            tags

            trunk

 

So I did:

 c:

 mkdir App

 cd App

 mkdir branches

 mkdir tags

 rails trunk

 

No dice.

	I've been doing development for the last few months with GTK on
ruby.  I need Rails for a project I'm starting.  The installer appears
to detect the existing installation sufficiently well to not step on it
(or %PATH%), but this is causing more problems (and even more later).
Namely, rails is not in my path, I'm not going to be able to follow the
tutorial.  Much more importantly, my rails aps are going to hit the
non-rails installation directory.

	 The simple solution (to me) is for rails to do the necessary
installs into any existing ruby install it finds.  I'm tempted to poke
into source & try to do it myself, but I'm afraid of there being a bunch
of places which hard-code the directory.

	 And yes, I'm going to be working on both projects now...

	 Help?

This is a little bit confusing since Instant Rails does not have an
installer, but let me take some educated gueses. 

The whole point of Instant Rails is to not modify your system
environment: no registry entries, no path changes. When you want to do
things in a particular instance of Instant Rails you have to do it
through the Instant Rails manager application ( InstantRails.exe). 

So, for example, when you want to use the "rails" command you would use
IR's menus and select the menu command "Rails Applications > Open Ruby
Console Window". That will open a console window, and in that console
window (only) IR *will* be on the path... as the first item in the path.
That way everything you do in that window will uses the Ruby/Rails that
belongs to that instance of IR. 

The same thing happens when you do other things from the IR manager
(like starting a Rails Apps with Mongrel) -- that instance of IR is put
on the path for that running instance only.
