$ rvm tools {identifier,path-identifier,strings,mirror,rvm-env}
Provides generic tools related to rvm environments for gaining information
about your current environment. Primarily used for scripting rvm.
Examples:
To get the expanded Ruby string for the current environment, you would run:
$ rvm tools identifier
To get the identifier for a folder (taking into account .rvmrc files and the like),
run this instead:
$ rvm tools path-identifier ~/path/to/directory
Lastly, you can expand example Ruby strings. E.g., to get the current ree version,
run:
$ rvm tools strings ree
In case of network/firewall problems, it is easy to define alternate download URLs:
$ rvm tools mirror
It is possible to use a "shebang" (#!/usr/...) line to select the interpreter
(eg, Ruby 1.9.3) which processes a script file. However, this will work only
on recent Linux kernels (2.6.27.9 and above).
First, you need to define the shebang wrapper:
$ rvm tools rvm-env ruby bash zsh
This will define:
/usr/bin/{ruby,bash,zsh}-rvm-env
Your scripts can then request the proper Ruby, using shebang:
#!/usr/bin/ruby-rvm-env 1.9.3
The script will be run using Ruby 1.9.3 from rvm.
Alternatively, here is a hack to make a script switch itself:
if !ENV['ruby_switch_flag']
ENV['ruby_switch_flag'] = '42'
system('rvm', '1.9.3', 'do', __FILE__, *ARGV)
exit 0
end
