NAME

Sah::Schema::simple_int_range - Simple integer range, e.g. 1-10 / -2-7

VERSION

This document describes version 0.004 of Sah::Schema::simple_int_range (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_int_range*");
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_int_range*");
    $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_int_range*'],
        },
        ...
    },
};
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  # INVALID (Not a range but single positive integer)

-2  # INVALID (Not a range but single negative integer)

"1-1"  # valid

"1-2"  # valid

"1 - 2"  # valid

"0-100"  # valid

"-1-2"  # valid

"-10--1"  # valid

"1-"  # INVALID (Missing end value)

"1-1.5"  # INVALID

"9-2"  # INVALID (start value cannot be larger than end value)

"1-2-3"  # INVALID (Invalid syntax)

" 1-2 "  # INVALID (Leading and trailing whitespace is currently not allowed)
