NAME
    Perinci::Sub::To::CLIOptSpec - Generate data structure convenient for
    producing CLI help/usage

VERSION
    This document describes version 0.06 of Perinci::Sub::To::CLIOptSpec
    (from Perl distribution Perinci-Sub-To-CLIOptSpec), released on
    2014-11-21.

SYNOPSIS
     use Perinci::Sub::To::CLIOptSpec qw(gen_cli_opt_spec_from_meta);
     my $cliospec = gen_cli_opt_spec_from_meta(meta => $meta);

FUNCTIONS
  gen_cli_opt_spec_from_meta(%args) -> [status, msg, result, meta]
    From Rinci function metadata, generate structure convenient for
    producing CLI help/usage.

    This function calls "Perinci::Sub::GetArgs::Argv"'s
    "gen_getopt_long_spec_from_meta()" (or receive it, if passed, to avoid
    calculating twice) and post-processes it: produce command usage line,
    format the options, include information from metadata, group the options
    by category. The resulting data structure is convenient to use when one
    produces a help message for a command-line program.

    Arguments ('*' denotes required arguments):

    *   common_opts => *hash*

        Will be passed to gen_getopt_long_spec_from_meta().

    *   ggls_res => *array*

        Full result from gen_getopt_long_spec_from_meta().

        If you already call "Perinci::Sub::GetArgs::Argv"'s
        "gen_getopt_long_spec_from_meta()", you can pass the *full*
        enveloped result here, to avoid calculating twice. What will be
        useful for the function is the extra result in result metadata
        ("func.*" keys in "$res->[3]" hash).

    *   lang => *str*

    *   meta* => *hash*

    *   meta_is_normalized => *bool*

    *   per_arg_json => *bool*

        Pass per_arg_json=1 to Perinci::Sub::GetArgs::Argv.

    *   per_arg_yaml => *bool*

        Pass per_arg_json=1 to Perinci::Sub::GetArgs::Argv.

    Return value:

    Returns an enveloped result (an array).

    First element (status) is an integer containing HTTP status code (200
    means OK, 4xx caller error, 5xx function error). Second element (msg) is
    a string containing error message, or 'OK' if status is 200. Third
    element (result) is optional, the actual result. Fourth element (meta)
    is called result metadata and is optional, a hash that contains extra
    information.

     (hash)
