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, UNLESS that code is a "BEGIN {}" block or a "use"
       statement.

       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.

SKIPPING TEST FROM INSIDE THE POD

       You can use a "BEGIN{}" block in the "=for test_synopsis" to check for specific conditions
       (e.g. if a module is present), and possibly skip the test.

       If you "die()" inside the "BEGIN{}" block and the die message begins with sequence "SKIP:"
       (note the colon at the end), the test will be skipped for that document.

         =head1 SYNOPSIS

         =for test_synopsis BEGIN { die "SKIP: skip this pod, it's horrible!\n"; }

             $x; # undeclared variable, but we skipped the test!

         =end

EXPORTED SUBROUTINES

   "all_synopsis_ok"
         all_synopsis_ok();

         all_synopsis_ok( dump_all_code_on_error => 1 );

       Checks the SYNOPSIS code in all your modules. Takes optional arguments as key/value pairs.
       Possible arguments are as follows:

       "dump_all_code_on_error"

         all_synopsis_ok( dump_all_code_on_error => 1 );

       Takes true or false values as a value. Defaults to: false. When set to a true value, if an
       error is discovered in the SYNOPSIS code, the test will dump the entire snippet of code it
       tried to test. Use this if you want to copy/paste and play around with the code until the
       error is fixed.

       The dumped code will include any of the "=for" code you specified (see "VARIABLE
       DECLARATIONS" section above) as well as a few internal bits this test module uses to make
       SYNOPSIS code checking possible.

       Note: you will likely have to remove the "#" and a space at the start of each line ("perl
       -pi -e 's/^#\s//;' TEMP_FILE_WITH_CODE")

   "synopsis_ok"
         use Test::More tests => 1;
         use Test::Synopsis;
         synopsis_ok("t/lib/NoPod.pm");
         synopsis_ok(qw/Pod1.pm  Pod2.pm  Pod3.pm/);

       Lets you test a single file. Note: you must setup your own plan if you use this subroutine
       (e.g. with "use Test::More tests => 1;").  Takes a list of filenames for documents
       containing SYNOPSIS code to test.

CAVEATS

       This module will not check code past the "__END__" or "__DATA__" tokens, if one is present
       in the SYNOPSIS code.

       This module will actually execute "use" statements and any code you specify in the "BEGIN
       {}" blocks in the SYNOPSIS.

       If you're using HEREDOCs in your SYNOPSIS, you will need to place the ending of the
       HEREDOC at the same indent as the first line of the code of your SYNOPSIS.

       Redefinition warnings can be turned off with

         =for test_synopsis
         no warnings 'redefine';
