NAME

       Test::Synopsis - Test your SYNOPSIS code

SYNOPSIS

	 # xt/synopsis.t (with Module::Install::AuthorTests)
	 use Test::Synopsis;
	 all_synopsis_ok();

	 # Or, run safe without Test::Synopsis
	 use Test::More;
	 eval "use Test::Synopsis";
	 plan skip_all => "Test::Synopsis required for testing" if $@;
	 all_synopsis_ok();

DESCRIPTION

       Test::Synopsis is an (author) test module to find .pm or .pod files under your lib directory and then make sure the example snippet code in
       your SYNOPSIS section passes the perl compile check.

       Note that this module only checks the perl syntax (by wrapping the code with "sub") and doesn't actually run the code.

       Suppose you have the following POD in your module.

	 =head1 NAME

	 Awesome::Template - My awesome template

	 =head1 SYNOPSIS

	   use Awesome::Template;

	   my $template = Awesome::Template->new;
	   $tempalte->render("template.at");

	 =head1 DESCRIPTION

       An user of your module would try copy-paste this synopsis code and find that this code doesn't compile because there's a typo in your
       variable name $tempalte. Test::Synopsis will catch that error before you ship it.

VARIABLE DECLARATIONS

       Sometimes you might want to put some undeclared variables in your synopsis, like:

	 =head1 SYNOPSIS

	   use Data::Dumper::Names;
	   print Dumper($scalar, @array, \%hash);

       This assumes these variables like $scalar are defined elsewhere in module user's code, but Test::Synopsis, by default, will complain that
       these variables are not declared:

	   Global symbol "$scalar" requires explicit package name at ...

       In this case, you can add the following POD sequence elsewhere in your POD:

	 =for test_synopsis
	 no strict 'vars'

       Or more explicitly,

	 =for test_synopsis
	 my($scalar, @array, %hash);

       Test::Synopsis will find these "=for" blocks and these statements are prepended before your SYNOPSIS code when being evaluated, so those
       variable name errors will go away, without adding unnecessary bits in SYNOPSIS which might confuse users.
