The parser does not automatically support negating or disabling long options by using the format -disable-option or -no-option. If such an option is placed last and has no value, the option will be treated as if it had not been specified. The parser does not support optional values - if an option is set to require a value, one must be present. the next argument is used as value (even if it starts with a -). Passing values to options can be done using the assignment operator: -v=value -verbose=value, or a space: -v value -verbose value, i.e. The long option verbose would be passed as -verbose or -verbose. Long options are more than one letter long and cannot be compacted together. The parsing mode for can be set to ParseAsLongOptions, in which case -abc will be parsed as the long option abc. In the default parsing mode, short options can be written in a compact form, for instance -abc is equivalent to -a -b -c. The option v would be specified by passing -v on the command line. The parser will treat everything after the option - (double dash) as positional arguments. The option - (single dash alone) is a special case, often meaning standard input, and not treated as an option. Options on the command line are recognized as starting with a single or double - character(s). The parser handles short names, long names, more than one name for the same option, and option values. doesn't start with a -) is stored as a "positional argument". QCommandLineParser provides the ability to define a set of options, parse the command-line arguments, and store which options have actually been used, as well as option values.Īny argument that isn't an option (i.e. QCoreApplication provides the command-line arguments as a simple list of strings.
