  output = ''
  FileUtils.cd(path) do
    output = %x|drush core-status --format=yaml|
  end
  begin # See self.installed?
    st = YAML.load(output)
  rescue Exception
    return false
  end
  return false unless st
  return false unless st.instance_of?(Hash)
  return (st['bootstrap'] =~ /Successful/) ? true : false
end

.installed?(site_path, project_name, project_path, options = {}) ⇒ Boolean

Returns true if the project at the given path is an enabled theme or an installed (enabled or disabled) module in the given site; returns false otherwise. The project’s path must be relative to the Drupal installation (e.g., ‘sites/all/modules’). Note that the project path is necessary because, in general, there may be several copies of the same modules at different locations within a platform (in ‘sites/all’, in ‘profiles/’ and in site-specific locations).

Options: verbose

Returns:

  • (Boolean)
