NAME

Sah::Schema::perl::modname_or_prefix - Perl module name (e.g. Foo::Bar) or prefix (e.g. Foo::Bar::)

VERSION

This document describes version 0.034 of Sah::Schema::perl::modname_or_prefix (from Perl distribution Sah-Schemas-Perl), released on 2020-06-19.

SYNOPSIS

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

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

 "Foo::Bar"  # valid

 "Foo::Bar::"  # valid

 "Foo/Bar"  # valid, becomes "Foo::Bar"

 "Foo/Bar/"  # valid, becomes "Foo::Bar::"

 "Foo-Bar"  # valid, becomes "Foo::Bar"

 "Foo-Bar-"  # valid, becomes "Foo::Bar::"

 "Foo|Bar"  # INVALID

DESCRIPTION

Contains coercion rule so inputing Foo-Bar or Foo/Bar will be normalized to Foo::Bar while inputing Foo-Bar- or Foo/Bar/ will be normalized to Foo::Bar::
