rbs

rbs is a Ruby port of Python's pbs.

It tries to make shelling out easier and nicer.

This sounds good!! how do I get it???

gem install rbs

Quick Examples

Query the en0 network interface:

require "rbs"
puts rbs.ifconfig "en0"

Check gcc's version:

require "rbs"
puts rbs.gcc(:version).lines.first

POST some JSON to an API:

require "rbs"
rbs.curl(:X, "POST", :"data-ascii", %{{"my":["example","json","document"]}})

Features

• rbs supports importing certain commands into the global namespace:

  require "rbs"
  rbs :echo
  echo "hello world"

• rbs tries to be smart about programs that have dashes in their names:

  require "rbs"
  rbs.llvm_gcc # tries `llvm_gcc` first, and then tries `llvm-gcc`

• For programs with really funky names, you can use the [] operator:

  require "rbs"
  rbs["ruby-1.9.3-p194", :version] # executes `ruby-1.9.3-p194 --version`

• rbs supports scopes, so if you'd like to run a bunch of commands as root:

  require "rbs"
  rbs.sudo do
    puts rbs.whoami
    rbs.rm :r, :f, "/"
  end

• You can also pass a Hash into an rbs command and it will be decomposed into arguments:

  require "rbs"
  rbs.configure prefix: "/usr/local", with_zlib_dir: "/path/to/zlib"
  # executes: `configure --prefix=/usr/local --with-zlib-dir=/path/to/zlib`
