get_config_setting(setting) click to toggle source

NOTE: Anything currently set with 'floatyhelper config set' will return a string, regardless of its intended type. Need to add typing one of these days.

# File lib/floatyhelper/config.rb, line 65
def self.get_config_setting(setting)
  data = load_data
  data['config'][setting]
end

load_data() click to toggle source

# File lib/floatyhelper/config.rb, line 32
def self.load_data
  File.write(fhfile, DEFAULT_CONF_FILE) unless File.exist?(fhfile)
  data = YAML.load_file(fhfile)
  # If someone is using an older version, ensure the conf file has
  # all the correct top-level keys. Only write it back if we modify
  # the data to add a top-level key.
  writeback = false
  ['config', 'vms', 'snapshots'].each do |key|
    if !data.keys.include?(key)
      data[key] = {}
      writeback = true
    end
  end

  # Config setting defaults
  VALID_SETTINGS.each do |setting, info|
    writeback = true if data['config'][setting].nil?
    data['config'][setting] ||= info['default']
  end

  write_data(data) if writeback
  data

set_config_setting(setting, value) click to toggle source

  write_data(data)
end

write_data(data) click to toggle source

It is up to the calling function to ensure the data object being passed in is a properly formatted hash. It should only be used to modify after reading the current state with load_data.

# File lib/floatyhelper/config.rb, line 59
def self.write_data(data)
  File.write(fhfile, data.to_yaml)
