NAME

Sah::Schema::perl::sortkey::modnames_with_optional_args - Array of Perl SortKey::* module names without the prefix, with optional args, e.g. ["Num::length", "Num::pattern_count=pattern,foo"]

VERSION

This document describes version 0.002 of Sah::Schema::perl::sortkey::modnames_with_optional_args (from Perl distribution Sah-SchemaBundle-SortKey), released on 2024-03-07.

SAH SCHEMA DEFINITION

[
  "array",
  {
    "of" => ["perl::sortkey::modname_with_optional_args", { req => 1 }],
    "x.element_completion" => ["perl_sortkey_modname_with_optional_args"],
    "x.perl.coerce_rules" => [
      [
        "From_str_or_array::expand_perl_modname_wildcard",
        { ns_prefix => "SortKey" },
      ],
    ],
  },
]

Base type: array

SYNOPSIS

Using with Data::Sah

To check data against this schema (requires Data::Sah):

use Data::Sah qw(gen_validator);
my $validator = gen_validator("perl::sortkey::modnames_with_optional_args*");
say $validator->($data) ? "valid" : "INVALID!";

The above validator returns a boolean result (true if data is valid, false if otherwise). To return an error message string instead (empty string if data is valid, a non-empty error message otherwise):

my $validator = gen_validator("perl::sortkey::modnames_with_optional_args", {return_type=>'str_errmsg'});
my $errmsg = $validator->($data);

Often a schema has coercion rule or default value rules, so after validation the validated value will be different from the original. To return the validated (set-as-default, coerced, prefiltered) value:

my $validator = gen_validator("perl::sortkey::modnames_with_optional_args", {return_type=>'str_errmsg+val'});
my $res = $validator->($data); # [$errmsg, $validated_val]

Data::Sah can also create validator that returns a hash of detailed error message. Data::Sah can even create validator that targets other language, like JavaScript, from the same schema. Other things Data::Sah can do: show source code for validator, generate a validator code with debug comments and/or log statements, generate human text from schema. See its documentation for more details.

Using with Params::Sah

To validate function parameters against this schema (requires Params::Sah):

use Params::Sah qw(gen_validator);

sub myfunc {
    my @args = @_;
    state $validator = gen_validator("perl::sortkey::modnames_with_optional_args*");
    $validator->(\@args);
    ...
}

Using with Perinci::CmdLine::Lite

To specify schema in Rinci function metadata and use the metadata with Perinci::CmdLine (Perinci::CmdLine::Lite) to create a CLI:

# in lib/MyApp.pm
package
  MyApp;
our %SPEC;
$SPEC{myfunc} = {
    v => 1.1,
    summary => 'Routine to do blah ...',
    args => {
        arg1 => {
            summary => 'The blah blah argument',
            schema => ['perl::sortkey::modnames_with_optional_args*'],
        },
        ...
    },
};
sub myfunc {
    my %args = @_;
    ...
}
1;

# in myapp.pl
package
  main;
use Perinci::CmdLine::Any;
Perinci::CmdLine::Any->new(url=>'/MyApp/myfunc')->run;

# in command-line
% ./myapp.pl --help
myapp - Routine to do blah ...
...

% ./myapp.pl --version

% ./myapp.pl --arg1 ...

Using on the CLI with validate-with-sah

To validate some data on the CLI, you can use validate-with-sah utility. Specify the schema as the first argument (encoded in Perl syntax) and the data to validate as the second argument (encoded in Perl syntax):

% validate-with-sah '"perl::sortkey::modnames_with_optional_args*"' '"data..."'

validate-with-sah has several options for, e.g. validating multiple data, showing the generated validator code (Perl/JavaScript/etc), or loading schema/data from file. See its manpage for more details.

Using with Type::Tiny

To create a type constraint and type library from a schema (requires Type::Tiny as well as Type::FromSah):

package My::Types {
    use Type::Library -base;
    use Type::FromSah qw( sah2type );

    __PACKAGE__->add_type(
        sah2type('perl::sortkey::modnames_with_optional_args*', name=>'PerlSortkeyModnamesWithOptionalArgs')
    );
}

use My::Types qw(PerlSortkeyModnamesWithOptionalArgs);
PerlSortkeyModnamesWithOptionalArgs->assert_valid($data);

DESCRIPTION

Array of Perl SortKey::* module names without the prefix and with optional args. Each element is of perl::sortkey::modname schema, e.g. Num::length, Num::pattern_count.

Contains coercion rule that expands wildcard, so you can specify:

Num::*

and it will be expanded to e.g.:

["Num::length", "Num::pattern_count"]

The wildcard syntax supports jokers (?, *, **), brackets ([abc]), and braces ({one,two}). See Module::List::Wildcard for more details.

CONTRIBUTING

To contribute, you can send patches by email/via RT, or send pull requests on GitHub.

Most of the time, you don't need to build the distribution yourself. You can simply modify the code, then test via:

% prove -l

If you want to build the distribution (e.g. to try to install it locally on your system), you can install Dist::Zilla, Dist::Zilla::PluginBundle::Author::PERLANCAR, Pod::Weaver::PluginBundle::Author::PERLANCAR, and sometimes one or two other Dist::Zilla- and/or Pod::Weaver plugins. Any additional steps required beyond that are considered a bug and can be reported to me.
