57 * Implements command-line parsing for Options objects.
59 * Typical usage (without error checking):
61 gmx::Options options("name", "description");
64 gmx::CommandLineParser(&options).parse(&argc, argv);
69 * \ingroup module_commandline
71 class CommandLineParser
75 * Creates a command-line parser that sets values for options.
77 * \param[in] options Options object whose options should be set.
78 * \throws std::bad_alloc if out of memory.
80 CommandLineParser(Options *options);
84 * Parses the command line.
86 * \throws std::bad_alloc if out of memory.
87 * \throws InvalidInputError if any errors were detected in the input.
89 * All command-line arguments are parsed, and an aggregate exception
90 * with all the detected errors is thrown in the end.
92 * Currently, the input parameters are not modified, but this may
93 * change if/when support for parsing only part of the options is
96 void parse(int *argc, char *argv[]);
98 * Parses the command line from a std::vector.
100 * \param[in] commandLine Array of command-line strings.
101 * \throws std::bad_alloc if out of memory.
102 * \throws InvalidInputError if any errors were detected in the input.
104 * \p commandLine should relate to the standard \c argv array
107 * This method is provided for convenience for cases where the command
108 * line needs to be stored before parsing.
110 * Currently, the input parameters are not modified, but this may
111 * change if/when support for parsing only part of the options is
114 * \see parse(int *, char *[])
