I would like to use RVM with tcsh; how do I do this?
As far as I can see, there are no "official" instructions for this. I followed the instructions on "Using RVM with tcsh", but this didn't work for me; in particular, I don't have access to the Ruby binaries ruby, bundle, irb, rspec, etc.
This worked well for me on OS X Yosemite 10.10.2, though it adds about a 5-second delay to opening a Terminal window each time due to the RVM initialization.
Create this file:
https://gist.github.com/chetstone/1361149
I put it in ~/.rvm/rvm.rb
chmod +x rvm.rb
Add to your .cshrc/.tcshrc:
alias rvm 'eval `~/.rvm/rvm.rb \!*`' rvm use ruby --default
ruby -v now returns the correct version.
What I did was get all rvm-related environment variables from bash with env | grep -i rvm.
I then copied them to my ~/.tcshrc, and substituted the ruby version with $ruby_version:
if ( ! $?ruby_version ) then
set ruby_version = `grep RUBY_VERSION ~/.rvm/environments/default | cut -d= -f2 | tr -d \' | sed 's/^ruby-//'`
end
setenv rvm_bin_path $HOME/.rvm/bin
setenv GEM_HOME $HOME/.rvm/gems/ruby-$ruby_version
setenv IRBRC $HOME/.rvm/rubies/ruby-$ruby_version/.irbrc
setenv MY_RUBY_HOME $HOME/.rvm/rubies/ruby-$ruby_version
setenv rvm_path $HOME/.rvm
setenv rvm_prefix $HOME
setenv PATH $HOME/.rvm/gems/ruby-$ruby_version/bin:$HOME/.rvm/gems/ruby-$ruby_version@global/bin:$HOME/.rvm/rubies/ruby-$ruby_version/bin:${PATH}:$HOME/.rvm/bin
setenv GEM_PATH $HOME/.rvm/gems/ruby-${ruby_version}:$HOME/.rvm/gems/ruby-${ruby_version}@global
$ruby_version will be set to the default; if it's empty; to use a different ruby version, I can do:
% set ruby_version = 1.9.3-p547
% source ~/.tcshrc
Using (some) rvm commands, such as rvm install or rvm list also seem to work; but rvm use doesn't (you need to use the $ruby-version workaround). I didn't check all the other commands, though.
