I'm fairly new to Emacs and have begun customising. I'm using Cask & Pallet and which is awesome for managing dependencies (similar to Bundler for Ruby projs) and it would be great if chruby.el could be installed via list-packages.

Are there any plans to put chruby.el on one of the repos such as MELPA (or Marmalade) - I'm completely unaware if this requires much work so apologies if I've underestimated the requirements to do this.

Thanks for chruby.el I'm a big fan of Chruby and I was pleasantly surprised that someone had created Emacs support for it.

It would be very nice if I could put a function like this in my ruby-mode hook, much like RVM's here: https://github.com/senny/rvm.el/blob/master/rvm.el#L165

Essentially it goes to the project root and finds a .ruby-version (and a .ruby-gemset, since it's rvm), then sets the correct ruby for me.

Can't seem to track this down, so I'm looking for some help. I'm hoping that I am just overlooking something dumb and obvious.

In my init I have:

(require 'chruby)
(chruby "ruby-2.1.1")

but it doesn't seem to have any effect. I verified the settings in ielm:

ELISP> (chruby "2.1.1")
("/Users/sme/.gem/ruby/2.0.0/bin" "/Users/sme/.rubies/ruby-2.1.1/bin")
ELISP> (chruby)
"ruby-2.1.1"

But using M-! to run ruby -v the system ruby is still run
ruby 2.0.0p247 (2013-06-27 revision 41674) [universal.x86_64-darwin13]

The value of exec-path checked with M-x describe-variable has the correct entries at the front:
("/Users/sme/.rubies/ruby-2.1.1/bin" "/Users/sme/.gem/ruby/2.0.0/bin" "/Users/sme/.gem/ruby/2.1.1/bin" "/Users/sme/.rubies/ruby-2.1.1/lib/ruby/gems/2.1.0/bin" "/Users/sme/Library/Haskell/bin" "/Users/sme/bin" "/\ usr/local/bin" "/usr/local/sbin" "/usr/local/share/npm/bin" "/usr/texbin" "/bin" "/usr/bin" "/sbin" "/usr/sbin" "/usr/X11/bin" "/Users/sme/.ec2" "/Users/sme/.go/bin" "/usr/local/Cellar/emacs/HEAD/libexec/emacs/2\ 4.3.50/x86_64-apple-darwin13.1.0")

I must be missing something. Thanks for any help!

The original chruby command allows specifying "fuzzy" ruby versions without the patch number, e.g. 2.4 which will load the highest matching available version from the 2.4 series.

Unfortunately, chruby.el does not understand this, and can actually mismatch if there's another version of ruby available which contains the "fuzzy" substring. Concretely, if you have 2.2.4 and 2.4.1 installed, calling chruby-use-corresponding when .ruby-version contains 2.4 will activate 2.2.4, not 2.4.1.

I'm a totally elisp newbie, but I think the fix will be on this line:

When running chruby.el without loading cl.el I was getting the following error:

Symbol's function definition is void: mapcan

I'm getting an error whenever I run "ruby -v":

(eval):1: unmatched "
ruby 1.9.3p429 (2013-05-15 revision 40747) [x86_64-darwin12.4.0]

I've just dropped chruby.el in my Prelude's personal folder and included the following two lines in my personal settings:

(require 'chruby)
(chruby "ruby-1.9.3-p429")

Any idea?
