NAME

Dist::Zilla::Plugin::GenPericmdScript - Generate Perinci::CmdLine script

VERSION

This document describes version 0.39 of Dist::Zilla::Plugin::GenPericmdScript (from Perl distribution Dist-Zilla-Plugin-GenPericmdScript), released on 2017-01-13.

SYNOPSIS

In dist.ini:

 ; generate a script, by default called bin/check-palindrome
 [GenPericmdScript]
 url=/My/Palindrome/check_palindrome

 ; generate another script, called bin/lssrv
 [GenPericmdScript / Gen_lssrv]
 url=/My/App/list_servers
 name=lssrv

After build, bin/check-palindrome and bin/lssrv will be created.

DESCRIPTION

After you add Rinci metadata to your function, e.g.:

 package My::Palindrome;
 $SPEC{check_palindrome} = {
     v => 1.1,
     args => {
         text => { schema=>'str*', req=>1, pos=>0 },
         ci   => { schema=>'bool*', cmdline_aliases=>{i=>{}} },
     },
     result_naked => 1,
 };
 sub check_palindrome {
     my %args = @_;
     my $text = $args{ci} ? lc($args{text}) : $args{text};
     $text eq reverse($text);
 }

you can create a command-line script for that function that basically is not much more than:

 #!perl
 use Perinci::CmdLine::Any;
 Perinci::CmdLine::Any->new(url => '/My/Palindrome/check_palindrome');

This Dist::Zilla plugin lets you automate the creation of such scripts.

Creating scripts. To create a single script, put this in dist.ini:

 [GenPericmdScript]
 ;required
 url=/My/Palindrome/check_palindrome
 ;optional
 abstract=Check if a text is a palindrome
 ; ...

To create more scripts, load the plugin again using the [Plugin/Name] syntax, e.g.:

 [GenPericmdScript / GenAnotherScript]
 ...

CONFIGURATION (SCRIPT SPECIFICATION)

url* => str

Riap URL. If the script does not contain subcommand, this should refer to a function URL. If the script contains subcommands, this should usually refer to a package URL.

subcommands => str

For creating a CLI script with subcommands. Value is a whitespace-separated entries of subcommand specification. Each subcommand specification must be in the form of SUBCOMMAND_NAME=URL[:SUMMARY]. Example:

 delete=/My/App/delete_item add=/My/App/add_item refresh=/My/App/refresh_item:Refetch an item from source

subcommands_from_package_functions => bool

Will be passed to Perinci::CmdLine::Gen backend.

include_package_functions_match => re

Will be passed to Perinci::CmdLine::Gen backend.

exclude_package_functions_match => re

Will be passed to Perinci::CmdLine::Gen backend.

name => str

Name of script to create. Default will be taken from function (or package) name, with _ replaced to -.

summary => str

Will be passed to Perinci::CmdLine::Gen backend (as script_summary).

cmdline => str

Select module to use. Default is Perinci::CmdLine::Any, but you can set this to classic (equals to Perinci::CmdLine::Classic), any (Perinci::CmdLine::Any), or lite (Perinci::CmdLine::Lite) or module name.

prefer_lite => bool (default: 1)

If set to 0 and you are using Perinci::CmdLine::Any, -prefer_lite option will be passed in the code.

enable_log => bool

Will be passed to Perinci::CmdLine object construction code (as log).

default_log_level => str

If set, will add this code to the generated script:

 BEGIN { no warnings; $main::Log_Level = "..." }

This can be used if you want your script to be verbose by default, for example.

pass_cmdline_object => bool

Will be passed to Perinci::CmdLine object construction code.

extra_urls_for_version => str

Comma-separated string, will be passed to Perinci::CmdLine object construction code (as array).

config_filename => str|array[str]

Will be passed to Perinci::CmdLine object construction code.

config_dirs => array[str]

Will be passed to Perinci::CmdLine object construction code.

ssl_verify_hostname => bool (default: 1)

If set to 0, will add this code to the generated script:

 $ENV{PERL_LWP_SSL_VERIFY_HOSTNAME} = 0;

This can be used if the Riap function URL is https and you don't want to verify.

load_modules => array[str]

Extra modules to load in the generated script.

code_before_instantiate_cmdline => str

code_after_end => str

default_format => str

Passed to Perinci::CmdLine object construction code.

skip_format => bool

Passed to Perinci::CmdLine object construction code.

use_utf8 => bool

Passed to Perinci::CmdLine object construction code.

allow_prereq => bool

Will be passed to Perinci::CmdLine::Gen backend.

per_arg_json => bool

Will be passed to Perinci::CmdLine::Gen backend.

per_arg_yaml => bool

Will be passed to Perinci::CmdLine::Gen backend.

CONFIGURATION (OTHER)

inline_generate_completer => bool (default: 1)

Perinci::CmdLine::Inline-generated scripts currently cannot do shell completion on its own, but relies on a separate completer script (e.g. if the script is bin/foo then the completer will be generated at bin/_foo). This option can be used to suppress the generation of completer script.

build_load_modules => array[str]

Load modules during build process.
