/** Provides parsing and storage of POSIX-like command line arguments (argc, argv).
|
|
||||||
* To use this class for CLI-option parsing, first define a set of valid options using
|
|
||||||
* the defineOption() method. An option can have several attributes: it can be required
|
|
||||||
* itself (its missing is considered as an error) and/or it can require a value.
|
|
||||||
* Options with optional values can be realized by defining the option to not need a
|
|
||||||
* value and use the syntax '--option=value' or '-o=value' on the command line.
|
|
||||||
* Every option can have different alternative labels; see defineOptionAlternative().
|
|
||||||
* A usage description (see usageDescription()) can be generated from the set of defined options (also see the
|
|
||||||
* addErrorCode(), setIntroductoryDescription() and setHelpOption() methods).
|
|
||||||
* \note The implemented parsing algorithm requires that all options have to be given at
|
|
||||||
* the beginning of the command line. Everything on the commandline after the first
|
|
||||||
* non-option (or option value) is considered as an argument.
|
|
||||||
* \attention Short option labels (single letter options) must not be digits
|
|
||||||
* (the option string itself not a possible value).
|
|
||||||
* Valid syntaxes are:
|
|
||||||
* \li program --long-option value -sdfgh -u=5 -i 7 --last=val arg1 arg2 arg3
|
|
||||||
* Here is a small code example:
|
|
||||||
* \code
|
|
||||||
* #include
|
|
||||||
* ArgvParser cmd; // the command line parser
|
|
||||||
*
|
|
||||||
* // init
|
|
||||||
* cmd.setIntroductoryDescription("This is foo written by bar.");
|
|
||||||
*
|
|
||||||
* //define error codes
|
|
||||||
* cmd.addErrorCode(0, "Success");
|
|
||||||
* cmd.addErrorCode(1, "Error");
|
|
||||||
*
|
|
||||||
* cmd.setHelpOption("h", "help", "Print this help");
|
|
||||||
*
|
|
||||||
* cmd.defineOption("version", ArgvParser::NoOptionAttribute, "Be verbose");
|
|
||||||
* cmd.defineOptionAlternative("verbose","v");
|
|
||||||
*
|
|
||||||
* cmd.defineOption("foo", ArgvParser::OptionRequiresValue, "Fooishness. Default value: 0");
|
|
||||||
*
|
|
||||||
* // finally parse and handle return codes (display help etc...)
|
|
||||||
* int result = cmd.parse(argc, argv);
|
|
||||||
*
|
|
||||||
* if (result != ArgvParser::NoParserError)
|
|
