rvm.rb View source

Modules: RVM

Adds settings and tasks for managing RVM installations.

require 'mina/rvm'

Common usage

 
task :environment do
  invoke :'rvm:use[ruby-1.9.3-p125@gemset_name]'
end

task :deploy => :environment do
  ...
end

Settings

Any and all of these settings can be overriden in your deploy.rb.

rvm_path

Sets the path to RVM.

You can override this in your projects if RVM is installed in a different path, say, if you have a system-wide RVM install.

 
set_default :rvm_path, "$HOME/.rvm/scripts/rvm"

Tasks

rvm:use[]

Uses a given RVM environment provided as an argument.

This is usually placed in the :environment task.

task :environment do
  invoke :'rvm:use[ruby-1.9.3-p125@gemset_name]'
end

task :'rvm:use', :env do |t, args|
  unless args[:env]
    print_error "Task 'rvm:use' needs an RVM environment name as an argument."
    print_error "Example: invoke :'rvm:use[ruby-1.9.2@default]'"
    die
  end

  queue %{
    echo "-----> Using RVM environment '#{args[:env]}'"
    if [[ ! -s "#{rvm_path}" ]]; then
      echo "! Ruby Version Manager not found"
      echo "! If RVM is installed, check your :rvm_path setting."
      exit 1
    fi

    source #{rvm_path}
    #{echo_cmd %{rvm use "#{args[:env]}" --create}} || exit 1
  }
end

rvm:wrapper[]

Creates a rvm wrapper for a given executable

This is usually placed in the :setup task.

task ::setup => :environment do
  ...
  invoke :'rvm:wrapper[ruby-1.9.3-p125@gemset_name,wrapper_name,binary_name]'
end

task :'rvm:wrapper', :env, :name, :bin do |t,args|
  unless args[:env] && args[:name] && args[:bin]
    print_error "Task 'rvm:wrapper' needs an RVM environment name, an wrapper name and the binary name as arguments"
    print_error "Example: invoke :'rvm:use[ruby-1.9.2@myapp,myapp,unicorn_rails]'"
    die
  end

  queue %{
    echo "-----> creating RVM wrapper '#{args[:name]}_#{args[:bin]}' using '#{args[:env]}'"
    if [[ ! -s "#{rvm_path}" ]]; then
      echo "! Ruby Version Manager not found"
      echo "! If RVM is installed, check your :rvm_path setting."
      exit 1
    fi

    source #{rvm_path}
    #{echo_cmd %{rvm wrapper #{args[:env]} #{args[:name]} #{args[:bin]} }} || exit 1
  }
