VERSION

This document describes version 0.496 of Perinci::CmdLine::Gen (from Perl distribution Perinci-CmdLine-Gen), released on 2020-04-01.

FUNCTIONS

gen_pericmd_script

Usage:

 gen_pericmd_script(%args) -> [status, msg, payload, meta]

Generate Perinci::CmdLine CLI script.

This function is not exported by default, but exportable.

Arguments ('*' denotes required arguments):

  • allow_prereq => array[perl::modname]

    Allow script to depend on these modules.

    Sometimes, as in the case of using Perinci::CmdLine::Inline, dependency to some modules (e.g. non-core XS modules) are prohibited because the goal is to have a free-standing script. This option allows whitelisting some extra modules.

    If you use Perinci::CmdLine::Inline, this option will be passed to it.

  • allow_unknown_opts => bool

    Will be passed to Perinci::CmdLine constructor.

  • cmdline => perl::modname (default: "Perinci::CmdLine::Any")

    Specify module to use.

  • code_after_end => str

  • code_before_instantiate_cmdline => str

  • config_dirs => array[str]

    Will be passed to Perinci::CmdLine constructor.

  • config_filename => str|hash|array[str|hash]

    Will be passed to Perinci::CmdLine constructor.

  • copt_help_enable => bool (default: 1)

  • copt_help_getopt => str

  • copt_version_enable => bool (default: 1)

  • copt_version_getopt => str

  • default_dry_run => bool

    Whether to set default_dry_run, will be passed to Perinci::CmdLine constructor.

  • default_format => str

    Set default format.

  • default_log_level => str

  • default_subcommand => str

    Will be passed to Perinci::CmdLine constructor.

  • env_name => str

    Will be passed to Perinci::CmdLine constructor.

  • exclude_package_functions_match => re

    Exclude package functions matching this pattern.

  • extra_urls_for_version => array[str]

    Will be passed to Perinci::CmdLine constructor.

  • include_package_functions_match => re

    Only include package functions matching this pattern.

  • interpreter_path => str

    What to put on shebang line.

  • load_module => array[perl::modname]

    Load extra modules.

  • log => bool

    Will be passed to Perinci::CmdLine constructor.

  • output_file => filename (default: "-")

    Path to output file.

  • overwrite => bool (default: 0)

    Whether to overwrite output if previously exists.

  • pack_deps => bool

    Whether to pack dependencies in Perinci::CmdLine::Inline script.

    Will be passed to Perinci::CmdLine's gen_inline_pericmd_script's pack_deps option.

  • pass_cmdline_object => bool

    Will be passed to Perinci::CmdLine constructor.

    Currently irrelevant when generating with Perinci::CmdLine::Inline.

  • per_arg_json => bool

    Will be passed to Perinci::CmdLine constructor.

  • per_arg_yaml => bool

    Will be passed to Perinci::CmdLine constructor.

  • pod => bool (default: 1)

    Whether to generate POD or not.

    Currently only Perinci::CmdLine::Inline generates POD.

  • prefer_lite => bool (default: 1)

    Prefer Perinci::CmdLine::Lite backend.

  • read_config => bool

    Will be passed to Perinci::CmdLine constructor.

  • read_env => bool

    Will be passed to Perinci::CmdLine constructor.

  • script_name => str

  • script_summary => str

  • script_version => str

    Use this for version number instead.

  • skip_format => bool

    Assume that function returns raw text which needs no formatting.

  • ssl_verify_hostname => bool (default: 1)

    If set to 0, will add: $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;' to code.

  • subcommands => hash

    Hash of subcommand entries, where each entry is "url[:summary]".

    An optional summary can follow the URL, e.g.:

     URL[:SUMMARY]

    Example (on CLI):

     --subcommand add=/My/App/add_item --subcommand bin='/My/App/bin_item:Delete an item'
  • subcommands_from_package_functions => bool

    Form subcommands from functions under package's URL.

    This is an alternative to the subcommands option. Instead of specifying each subcommand's name and URL, you can also specify that subcommand names are from functions under the package URL in url. So for example if url is /My/App/, hen all functions under /My/App are listed first. If the functions are:

     foo
     bar
     baz_qux

    then the subcommands become:

     foo => /My/App/foo
     bar => /My/App/bar
     "baz-qux" => /My/App/baz_qux
  • url* => riap::url

    URL to function (or package, if you have subcommands).

  • use_cleanser => bool

    Whether to use data cleansing before outputting to JSON.

  • use_utf8 => bool

    Whether to set utf8 flag on output, will be passed to Perinci::CmdLine constructor.

  • validate_args => bool

    Will be passed to Perinci::CmdLine constructor.

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 (payload) is optional, the actual result. Fourth element (meta) is called result metadata and is optional, a hash that contains extra information.

Return value: (any)
