GENGETOPT(1)

NAME
gengetopt - manual page for gengetopt 2.22.6

SYNOPSIS
gengetopt [OPTIONS]...

DESCRIPTION
GNU gengetopt 2.22.6

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

-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 current 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 otherwise

-u, --unamed-opts[=STRING]
    accept options without names (e.g., file names) (default=`FILES')

The parser generated is thought to be used to parse the command line arguments. However, you can also generate parsers for configuration files, or strings that contain the arguments to parse, by using the following two options.

-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, respectively.

-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 program 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) instead of generating code

--show-detailed-help
    show the output of --detailed-help (i.e., including details and hidden options) instead of generating code

--show-version
    show the output of --version instead of generating code
