NAME

Sah::Schema::latin_letter - Latin letter, i.e. A-Z or a-z

VERSION

This document describes version 0.005 of Sah::Schema::latin_letter (from Perl distribution Sah-Schemas-Str), released on 2022-06-08.

SYNOPSIS

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

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

"A"  # valid

"AB"  # INVALID (Multiple letters)

1  # INVALID (Non-letter)

";"  # INVALID (Non-letter)

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, and sometimes one or two other Dist::Zilla plugin and/or Pod::Weaver::Plugin. Any additional steps required beyond that are considered a bug and can be reported to me.
