Programatic use of guard

The Guardfile DSL can also be used in a programmatic fashion by calling Guard::Dsl.evaluate_guardfile.

Available options are as follow:

• :guardfile - The path to a valid Guardfile.
• :guardfile_contents - A string representing the content of a valid Guardfile.

Remember, without any options given, Guard will look for a Guardfile in your current directory and if it does not find one, it will look for it in your $HOME directory.

Evaluate a Guardfile:

require 'guard'

Guard.setup
Guard.start(:guardfile => '/path/to/Guardfile')

Evaluate a string as Guardfile:

require 'guard'

Guard.setup

guardfile = <<-EOF
  guard 'rspec' do
    watch(%r{^spec/.+_spec\.rb$})
  end
EOF

Guard.start(:guardfile_contents => guardfile)
