NAME

Sah::Schema::example::recurse1

VERSION

This document describes version 0.009 of Sah::Schema::example::recurse1 (from Perl distribution Sah-Schemas-Examples), released on 2021-07-30.

SYNOPSIS

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

use Data::Sah qw(gen_validator);
my $validator = gen_validator("example::recurse1*");
say $validator->($data) ? "valid" : "INVALID!";

# Data::Sah can also create validator that returns nice error message string
# and/or coerced value. Data::Sah can even create validator that targets other
# language, like JavaScript. All from the same schema. See its documentation
# for more details.

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

use Params::Sah qw(gen_validator);

sub myfunc {
    my @args = @_;
    state $validator = gen_validator("example::recurse1*");
    $validator->(\@args);
    ...
}

To specify schema in Rinci function metadata and use the metadata with Perinci::CmdLine 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 => ['example::recurse1*'],
        },
        ...
    },
};
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 ...

DESCRIPTION

This schema will cause the resolver Data::Sah::Resolve to bail because it recurses to itself.
