Hi
Is there a way to use Ruby as a scripting language for Emacs?
(There’s a way to use Python for that [1], but I haven’t managed to
find the equivalent for Ruby)

Try EL4R: Emacs Lisp for Ruby,

The emacs wiki is pretty comprehensive when searching for stuff like

Thanks, Bil
EmacsRuby is truly what I was looking for. Unfortunately, it seems to
have some problems working on the Windows platform. Since the author
expressed interest in attempts to run EmacsRuby under Win32, I sent
him a detailed account of the problems I encountered. I’ll attach it
here, maybe someone would benefit:

Hi there
You mentioned in EmacsRub’s homepage that you don’t have access to a
Windows machine. I have Windows XP Pro as my desktop workstation, so
I’ll share my attempt to install EmacsRuby on Windows. Ruby version:
ruby 1.8.4 (2005-12-24) [i386-mswin32] (pretty much the current stable
standard)
- Attempting to download and install EmacsRuby in the recommended way:
ruby -ropen-uri -e
‘URI(“http://www.rubyist.net/~rubikitch/archive/el4r-1.0.3.tar.gz”).read.display’
el4r-1.0.3.tar.gz
doesn’t work. The resulting local file el4r-1.0.3.tar.gz is
corrupted for some reason (manual download through the browser worked,
however).
- Windows machine don’t normally have tar (I do), let along the tar +
gzip combination (even I don’t :-(), so trying to expand through:
tar xzf el4r-1.0.3.tar.gz
doesn’t work. Have you considered a gem or at least a Zip release?
- Running setup.rb worked. However File.expand_path(“~”) didn’t work
within the various files in bin. Strangely enough,
File.expand_path(“~”) worked fine in IRB, but trying
File.expand_path(s) where s contains the ~ character produced the
following exception trying to run the first of two setup-lines (“ruby
-S el4r-rctool -p”):
C:/ruby/bin/el4r-rctool:189: (eval):1:in expand_path': couldn't find HOME environment -- expanding ~/.el4r’ (ArgumentError)
from (eval):1
I solved this by replacing within el4r-rctool all “~” in paths to “/”,
which is the directory Emacs uses as HOME. After that, the two setup
lines:
ruby -S el4r-rctool -p
ruby -S el4r-rctool -i
executed appearantly without exception.
But when I entered Emacs and ran el4r-boot, I got a message:
“el4r instance dead”
At that point, I tried running the tests:
ruby bin/el4r-runtest testing/test-el4r.rb --batch -l testlog
–emacs=[emacs binary name]
but again received the exception “couldn’t find HOME environment”.
At this point I gave up 
Please let me know if there’s anything I can do to help you stabilize
el4r for Windows, since I’m very interested in programming Emacs with
Ruby.
