Set rvm default interpreter in user's .rvmrc?

I'm curious if it's possible to set my default开发者_C百科 Ruby interpreter within my $HOME/.rvmrc file (i.e. the equivalent of a rvm --default use 1.9.2).

I tried setting rvm_ruby_interpreter and rvm_ruby_version, but no luck.

Just cleaning out my unanswered questions... I ended up basically taking Phrogz's suggestion and adding this to my .zprofile:

RVM_DEFAULT=ruby-1.9.3-p194@home
if [ -x ~/.rvm/bin/rvm-prompt ] && [ "$(~/.rvm/bin/rvm-prompt)" != $RVM_DEFAULT ] ; then
  rvm use $RVM_DEFAULT
fi

Looking back it's kind of a weird question, probably due to the fact that I was new to rvm and relatively new to Ruby (but familiar with Unix and dotfiles).

You can't in the $HOME/.rvmrc or /etc/rvmrc file, but you can in project .rvmrc files by typing in rvm <interpreter>. So if you want 1.9.2 for one project, but ree for a different, type in rvm 1.9.2 in the first project's .rvmrc file, and rvm ree in the other project's .rvmrc file. You can also automatically activate gemsets this way.

If you have projects using .rvmrc (or .ruby-version / .ruby-gemset), and want to be sure your home directory sets those envars to something else (no matter how many times you cd here and there), try this in ~/.bashrc:

PROMPT_COMMAND='[[ $PWD = $HOME ]] && (rvm use default; rvm gemset use global) > /dev/null'

Substituting your favorite flavors for default and global, of course.
