TextMate's Execute and Update ‘# =>’ Markers evaluates with ruby 1.8 instead of 1.9

Question

In TextMate 2, Execute and Update ‘# =>’ Markers menu action updates the markers in the following code as if I am running ruby 1.8 even though my TM_RUBY environment variable is set to ~/.rvm/rubies/ruby-1.9.3-p286/bin/ruby:

v = RUBY_VERSION # => "1.8.7"
puts "".singleton_class
puts v
# ~> -:2: undefined method `singleton_class' for "":String (NoMethodError)

Running the same code in TextMate 2, on the other hand, returns the expected command output:

#<Class:#<String:0x007fcf418941b8>>
1.9.3

This is a wonderful feature and it would be a real shame if it is limited to ruby 1.8. I suspect, however, that this may be peculiar to my setup (I have actually seen it work with 1.9 code here: http://ruby-kickstart.com/). Execute and Update ‘# =>’ Markers menu action is defined in the Ruby bundle where it calls xmpfilter from rcodetools:

#!/usr/bin/env bash

[[ -f "${TM_SUPPORT_PATH}/lib/bash_init.sh" ]] && . "${TM_SUPPORT_PATH}/lib/bash_init.sh"

export RUBYLIB="$TM_BUNDLE_SUPPORT/vendor/rcodetools/lib${RUBYLIB:+:$RUBYLIB}"
export TM_RUBY=$(which "${TM_RUBY:-ruby}")

"${TM_RUBY}" -r "${TM_SUPPORT_PATH}/lib/ruby1.9/add_1.8_features.rb" -- "$TM_BUNDLE_SUPPORT/vendor/rcodetools/bin/xmpfilter"

The file add_1.8_features.rb only adds a few legacy methods to the String and File classes (e.g. grep and remove). Indeed, this enables it to support ruby 1.9 (see https://github.com/textmate/ruby.tmbundle/blob/master/Support/vendor/rcodetools/CHANGES).

At this point I am not even quite sure where does ruby 1.8 come from in the first place. Even passing the explicit path to the latest ruby instead of "${TM_RUBY}" in the last line above does not change the output.

I would be very grateful for any help that would allow me to use this (or equivalent) menu action in TextMate.

This is a good reference.

Make sure you are running all the new versions.

Out of the box, rvm ships with a ruby binary, typically in ~/.rvm/bin (or, in system wide installs, inside of /usr/local/bin), that will perform the following steps before executing ruby:

Load up RVM
Look for any RVMRC files and load them
Execute as a normal ruby

This approach makes it possible to have the ruby switched on a per-project basis without any extra work. With rvm installed, this is a matter of taking the full path to rvm-auto-ruby, found via:

$ which rvm-auto-ruby

And in the advanced section of the textmate preferences, either adding or changing the TM_RUBY variable to point to the given path, like shown in this screenshot with an example installation.
