NAME

Sah::Schema::simple_uint_seq - Simple unsigned integer sequence, e.g. 1,3,12

VERSION

This document describes version 0.004 of Sah::Schema::simple_uint_seq (from Perl distribution Sah-Schemas-IntRange), released on 2021-07-17.

SYNOPSIS

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

use Data::Sah qw(gen_validator);
my $validator = gen_validator("simple_uint_seq*");
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("simple_uint_seq*");
    $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 => ['simple_uint_seq*'],
        },
        ...
    },
};
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 ...

Sample data:

""  # INVALID (Empty string)

"1-2"  # INVALID (A range m-n is not valid in simple integer sequence)

"1,"  # INVALID (Dangling comma is currently not allowed)

"1,,2"  # INVALID (Multiple commas are currently not allowed)

1.2  # INVALID (Float)

1  # valid

"1,2"  # valid

"1 , 2"  # valid

"1 , 2,3"  # valid

"1,2,-3,4"  # INVALID (Negative)
