Member Function Documentation

getArgDocString()

inline_t std::string cli::commands::PositionalArgumentBase::getArgDocString ( const docwriting::DocWriter &  writer ) const

overridevirtual

Get the argument documentation string for the argument.

This string is used in the Usage section of the help message for a command and displays a textual representation of the arguments attributes (e.g. if it is required or repeatable, ...).

Parameters

writer

The documentation writer to use.

Returns

The argument documentation string for the argument.

Implements cli::commands::ArgumentBase.

getOptionsDocString()

inline_t std::string cli::commands::PositionalArgumentBase::getOptionsDocString ( const docwriting::DocWriter &  writer ) const

overridevirtual

Get the options documentation string for the argument.

This string is used in the Options section of the help message for a command, where each argument is listed with its description.

Parameters

writer

The documentation writer to use.

Returns

The options documentation string for the argument.

Implements cli::commands::ArgumentBase.
