GENGETOPT(1) User Commands GENGETOPT(1) NAME gengetopt - manual page for gengetopt 2.23 SYNOPSIS gengetopt [OPTION]... DESCRIPTION This program generates a C function that uses getopt_long function to parse the command line options, validate them and fill a struct. -h, --help Print help and exit --detailed-help Print help, including all details and hidden options, and exit --full-help Print help, including hidden options, and exit -V, --version Print version and exit Main options: -i, --input=filename input file (default std input) -f, --func-name=name name of generated function (default=`cmdline_parser') -a, --arg-struct-name=name name of generated args info struct (default=`gengetopt_args_info') -F, --file-name=name name of generated file (default=`cmdline') --output-dir=path output directory if this option is not specified, the files are generated in the cur- rent directory. --header-output-dir=path header output directory --src-output-dir=path source output directory -c, --c-extension=ext extension of c file (default=`c') -H, --header-extension=ext extension of header file (default=`h') -l, --long-help long usage line in help The usage line will print all the options, e.g., sample1 -iINT|--int-opt=INT [-h|--help] --default-optional by default, an option is considered optional if not specified other- wise -u, --unnamed-opts[=STRING] accept options without names (e.g., file names) (default=`FILE') --unamed-opts[=STRING] synonym for --unnamed-opts, accepted for backwards compatibility (default=`FILE') The parser generated is thought to be used to parse the command line argu- ments. However, you can also generate parsers for configuration files, or strings that contain the arguments to parse, by using the following two op- tions. -C, --conf-parser generate a config file parser -S, --string-parser generate a string parser (the string contains the command line) Additional options: -G, --include-getopt adds the code for getopt_long in the generated C file -n, --no-handle-help do not handle --help|-h automatically If --no-handle-help is specified, the command line option --help|-h will not be handled automatically, so the programmer will be able to print some other information; then the function for printing the standard help output can be used; this function is called <parser-name>_print_help. Notice that, although the programmer can handle --help|-h manually, the parser will return after finding such option: the other command line options, if any, will be ignored. In case you want to have full control on --help|-h, you should use --ho-help. --no-help do not add --help|-h automatically With this option you can disable the automatic addition of options --help|-h. The programmer will then be able to add this option in the input file and handle it as he sees fit. Notice that --no-help will also disable the automatic options --detailed-help and --full-help. The programmer can still define options with short character h as he wants, but he cannot define options help, unless he specifies --no-help (otherwise an error will be printed). -N, --no-handle-version do not handle --version|-V automatically --no-version do not add --version|-V automatically See above the details about --no-handle-help and --no-help, respec- tively. -e, --no-handle-error do not exit on errors With this option, if the generated parser encounters an error (e.g., an unknown option) it does not make the main program exit; instead, the parser function returns a value different 0, and the main pro- gram can print a help message. --show-required[=STRING] in the output of help will specify which options are mandatory, by using the optional passed string (default=`(mandatory)') --strict-hidden completely hide hidden options -g, --gen-version put gengetopt version in the generated file (default=on) --set-package=STRING set the package name (override package defined in the .ggo file) --set-version=STRING set the version number (override version defined in the .ggo file) --show-help show the output of --help instead of generating code --show-full-help show the output of --full-help (i.e., including hidden options) in- stead of generating code --show-detailed-help show the output of --detailed-help (i.e., including details and hid- den options) instead of generating code --show-version show the output of --version instead of generating code Please refer to the info manual for further explanations.
