run Ruby from a CD in MS Windows

[smartpig]

I am new to Ruby.
I have a project that requires running an application from CD without
pre-install software on a user's pc (Windows OS). I was planning to use
java but the jre is too large (about 50 mg). My client want the
application + its runtime lib/engine less than 10 mb.
I like try Ruby but I don't know if Ruby can meet my client's
requirement?
I installed Ruby 1.8.2 on my pc, it takes about 30 mb space. Since my
application need only do a few simple things such as: check Windows
registry, create a socket to talk to another application and openning a
dialog box. I think I only burn a few dlls and ruby scripts to the CD
but I don't konw which are need. Can some give me a guide? Thanks for
help!

You can package up your ruby application plus ruby and everything needed with
Ruby2Exe, which will come out to be quite small, and a regular windows
executable. Plop that on your cd and you're done.

I did this very thing about 1.5 years ago for a very large client (which
makes most of the microprocessors out there). We couldn't fit the JRE on the
CD because we were running out of space. We also needed to fit in under
10MB. Ruby worked out well for this. You don't need a lot of the libraries
that come with the full-blown Ruby install. As I recall, I got it down to
under 5MB (and we were doing things like checking the windows registry).

The way I approached it was to first got through my Windows Ruby installation
and start removing libraries/dlls until stuff stopped working.

If you need a GUI library, I would suggest you check out FLTK as it is very
small.
