## Detailed Description

List of command-line option descriptions.

Use addOptions(const std::string&) to add Descriptions.

## Member Function Documentation

Descriptions & addOptions | ( | const std::string & | caption = `""`,
|  | std::initializer_list< Description > && | options = `{}`
| ) |  |

Sets the command-line tool caption and starts adding Descriptions.

Usage example:

CommandLine::Descriptions desc;
desc.addOptions ("myTool") // Set caption to "myTool"
("help", "produce help message") // add switch -help
("opt1", string(), "option 1") // add string option -opt1
("opt2", string(), "option 2") // add string option -opt2
;

Note
  The operator() is used for every additional option.

Or with initializer list :

CommandLine::Descriptions desc;
desc.addOptions ("myTool", // Set caption to "myTool"
{{"help", "produce help message", Description::kBool}, // add switch -help
{"opt1", "option 1", Description::kString}, // add string option -opt1
{"opt2", "option 2", Description::kString}} // add string option -opt2
);

Parameters

  [in] | caption | the caption of the command-line tool.
  [in] | options | initializer list with options

Returns
  a reverense to *this.

bool parse | ( | int | ac,
|  | char * | av[],
|  | VariablesMap & | result,
|  | FilesVector * | files = `nullptr`
| ) |  | const

Parse the command-line.

Parameters

  [in] | ac | count of command-line parameters
  [in] | av | command-line as array of strings
  [out] | result | the parsing result
  [out] | files | optional list of elements on the command line that are not handled by options parsing

void print | ( | std::ostream & | os | ) | const

Print a brief description for the command-line tool into the stream `os`.

The description includes the help strings for all options.

Descriptions & operator() | ( | const std::string & | name,
|  | const std::string & | help
| ) |  |

Add a new switch.

Only

Returning a reference to *this, enables chaining of calls to operator()(const std::string&, const std::string&).

Parameters

  [in] | name | of the added option.
  [in] | help | a help description for this option.

Returns
  a reference to *this.

Descriptions& operator() | ( | const std::string & | name,
|  | const Type & | inType,
|  | std::string | help
| ) |  |

Add a new option of type `inType`.

Currently only std::string is supported.

Descriptions& operator() | ( | const std::string & | name,
|  | const std::string & | inType,
|  | std::string | help
| ) |  |

Add a new option with a string as parameter.
