enum class	Exceptions {   NoCommandGiven = 1 , UnknownCommand = 2 , ParsingOptions =10 , ParsingCommand =20 ,   MissingOptionValue =11 , IllegalOptionNameContinuation =12 , MissingParameterValue =21 , END_OF_ENUM }

Enumeration Details:

DryRunModes

enum class DryRunModes

strong

---

Dry run modes.

Enumerator
Off	No dry run.
CLIArgs	Displays the results of the command line argument parsing.
CLIDeclarations	Just displays the cli setup. This is more for debugging or interested users.
Application	Dry run on application level: Given commands are invoked, nothing is executed, but probably log information is written. Application specific behavior. This is the default if no argument is given to the dry-run opton

Exceptions

enum class Exceptions

strong

---

Exceptions of module alib::cli. As usual with class Exception , some of the exceptions are "inner exceptions" that are caught internally and re-thrown with more information and a different exception code.

The in this respect "external" exceptions that have to be caught by users of the library, are:

• NoCommandGiven,
• UnknownCommand,
• ParsingOptions and
• ParsingCommand.

Enumerator
NoCommandGiven	Unknown command given.
UnknownCommand	Unknown command given.
ParsingOptions	General option parse error. Adds option help text.
ParsingCommand	General parameter parse error. Adds command help text.
MissingOptionValue	Missing argument when reading option. (Will be generalized with ParsingOptions.)
IllegalOptionNameContinuation	An option was given in long name, but continued after its name in an undefined way. (Will be generalized with ParsingOptions.)
MissingParameterValue	Missing argument when reading parameter. (Will be generalized with ParameterError.)
