Constructor Details

#initialize(key: nil, env_name: nil, description: nil, short_option: nil, default_value: nil, verify_block: nil, is_string: true, type: nil, optional: false) ⇒ ConfigItem

Creates a new option

Parameters:

  • key (Symbol) (defaults to: nil) —

    the key which is used as command paramters or key in the fastlane tools

  • env_name (String) (defaults to: nil) —

    the name of the environment variable, which is only used if no other values were found

  • description (String) (defaults to: nil) —

    A description shown to the user

  • short_option (String) (defaults to: nil) —

    A string of length 1 which is used for the command parameters (e.g. -f)

  • default_value (defaults to: nil) —

    the value which is used if there was no given values and no environment values

  • verify_block (defaults to: nil) —

    an optional block which is called when a new value is set. Check value is valid. This could be type checks or if a folder/file exists You have to raise a specific exception if something goes wrong. Append .red after the string

  • is_string (defaults to: true) —

    *DEPRECATED: Use ‘type` instead* (Boolean) is that parameter a string? Defaults to true. If it’s true, the type string will be verified.

  • type (Class) (defaults to: nil) —

    the data type of this config item. Takes precedence over ‘is_string`

  • optional (Boolean) (defaults to: false) —

    is false by default. If set to true, also string values will not be asked to the user
