=head1 NAME

Sah::Schema::perl::funcname - Perl function name, either qualified with package name (e.g. Foo::subname) or unqualified (e.g. subname)

=head1 VERSION

This document describes version 0.042 of Sah::Schema::perl::funcname (from Perl distribution Sah-Schemas-Perl), released on 2021-12-01.

=head1 SYNOPSIS

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

 use Data::Sah qw(gen_validator);
 my $validator = gen_validator("perl::funcname*");
 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 L<Params::Sah>):

 use Params::Sah qw(gen_validator);

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

To specify schema in L<Rinci> function metadata and use the metadata with
L<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::funcname*'],
         },
         ...
     },
 };
 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 ...

=head1 DESCRIPTION

=head1 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 L<Dist::Zilla>,
L<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.
