Type Members

1.  case class ExcessArguments(args: Seq[String]) extends ScallopException with Product with Serializable

   Thrown when user provides excess arguments that can't be matched by trailing arg options

2.  case class GenericScallopException(msg: String) extends ScallopException with Product with Serializable
3.  case class Help(command: String) extends Exception with ScallopResult with Product with Serializable

   Thrown when user requested help output (via "--help")

4.  case class IdenticalOptionNames(mess: String) extends ScallopException with Product with Serializable

   Thrown when several options and/or trailing arguments have identical names in definition - making it impossible to distinguish between them.

5.  case class IllegalOptionParameters(mess: String) extends ScallopException with Product with Serializable

   Thrown when user tried to create an option with some illegal parameters

   • for example, with digit as the first character in opton name.
6.  case class IncompleteBuildException() extends ScallopException with Product with Serializable

   Thrown when user tried to extract the value of an option before the call to verify in ScallopConf.

7.  case class MajorInternalException() extends ScallopException with Product with Serializable

   This is a special case of exception - the one you should never see.

   This is a special case of exception - the one you should never see. If you actually saw it, there is a sure bug lurking somewhere. In such cases, please file a bug on project page!

8.  case class OptionNameGuessingFailure() extends ScallopException with Product with Serializable

   Thrown when option name guessing fails on one of the options.

9.  case class OptionNameGuessingUnsupported() extends ScallopException with Product with Serializable

   Thrown when option name guessing is not available on the platform (currently JS and Native)

10.  case class RequiredOptionNotFound(name: String) extends ScallopException with Product with Serializable

    Thrown when parser failed to find arguments to option (marked as 'required') in the input arguments.

11.  abstract class ScallopException extends Exception with ScallopResult

    Parent class for all exceptions thrown from this library.

12.  sealed trait ScallopResult extends AnyRef

    Parent trait for all not-positive results that can be resulted from this library (including help and exits)

13.  case class UnknownOption(optionName: String) extends ScallopException with Product with Serializable

    Thrown when user provides Scallop with unknown option name in the arguments or requests unknown option result from parser.

14.  case class ValidationFailure(mess: String) extends ScallopException with Product with Serializable

    Thrown when the validation failed on some option.

15.  case class WrongOptionFormat(optionName: String, args: String, msg: String) extends ScallopException with Product with Serializable

    Thrown when arguments to some option do not satisfy that option's value converter (it returns Left in such case).
