NAME

       HTML::Template::PerlInterface - perl interface of HTML::Template::Pro

SYNOPSIS

       This help is only on perl interface of HTML::Template::Pro.  For syntax of html template
       files you should see "SYNOPSIS" in HTML::Template::SYNTAX.

       First you make a template - this is just a normal HTML file with a few extra tags, the
       simplest being <TMPL_VAR>

       For example, test.tmpl:

         <html>
         <head><title>Test Template</title>
         <body>
         My Home Directory is <TMPL_VAR NAME=HOME>
         <p>
         My Path is set to <TMPL_VAR NAME=PATH>
         </body>
         </html>

       See HTML::Template::SYNTAX for their syntax.

       Now create a small CGI program:

         #!/usr/bin/perl -w
         use HTML::Template::Pro;

         # open the html template
         my $template = HTML::Template::Pro->new(
               filename => 'test.tmpl',
               case_sensitive=> 1);

         # fill in some parameters
         $template->param(HOME => $ENV{HOME});
         $template->param(PATH => $ENV{PATH});

         # send the obligatory Content-Type and print the template output
         print "Content-Type: text/html\n\n";

         # print output
         $template->output(print_to=>\*STDOUT);

         # this would also work.
         # print $template->output();

         # this would also work. It is faster,
         # but (WARNING!) not compatible with original HTML::Template.
         # $template->output();

       If all is well in the universe this should show something like this in your browser when
       visiting the CGI:

         My Home Directory is /home/some/directory
         My Path is set to /bin;/usr/bin

       For the best performance it is recommended to use case_sensitive=>1 in new() and
       print_to=>\*STDOUT in output().

       Note that (HTML::Template::Pro version 0.90+) output(), called in void context, also
       prints to stdout using built-in htmltmplpro C library calls, so the last call
       "$template->output();" might be, in fact, the fastest way to call output().

       IMPORTANT NOTE: you can safely write

         my $template = HTML::Template->new( ... options ...)
               or even
         my $template = HTML::Template::Expr->new( ... options ...)

       with HTML::Template::Pro, because in absence of original HTML::Template and
       HTML::Template::Expr HTML::Template::Pro intercepts their calls.

       You can also use all three modules and safely mix their calls (benchmarking may be the
       only reason for it).  In case you want to mix calls to HTML::Template::Expr and
       HTML::Template::Pro, the only proper usage of their load is

       use HTML::Template; use HTML::Template::Expr; use HTML::Template::Pro;

       Of course, if you don't plan to mix them (in most cases) it is enough to simply write

       use HTML::Template::Pro;

       Simply use HTML::Template::Pro, it supports all functions of HTML::Template::Expr.

DESCRIPTION

       HTML::Template::Pro is a fast C/perl+XS implementation of HTML::Template and
       HTML::Template::Expr.  See HTML::Template::Pro for details.

       It fully supports template language of HTML::Template as described in
       HTML::Template::SYNTAX.

       Briefly,

       "This module attempts to make using HTML templates simple and natural.  It extends
       standard HTML with a few new HTML-esque tags - <TMPL_VAR>, <TMPL_LOOP>, <TMPL_INCLUDE>,
       <TMPL_IF>, <TMPL_ELSE> and <TMPL_UNLESS>.  The file written with HTML and these new tags
       is called a template.  It is usually saved separate from your script - possibly even
       created by someone else!  Using this module you fill in the values for the variables,
       loops and branches declared in the template.  This allows you to separate design - the
       HTML - from the data, which you generate in the Perl script."

       Here is described a perl interface of HTML::Template::Pro and HTML::Template +
       HTML::Template::Expr.  See DISTINCTIONS for brief summary of distinctions between
       HTML::Template::Pro and HTML::Template.

METHODS

   new()
       Call new() to create a new Template object:

         my $template = HTML::Template->new( filename => 'file.tmpl',
                                             option => 'value'
                                           );

       You must call new() with at least one name => value pair specifying how to access the
       template text.  You can use "filename => 'file.tmpl'" to specify a filename to be opened
       as the template.  Alternately you can use:

         my $t = HTML::Template->new( scalarref => $ref_to_template_text,
                                      option => 'value'
                                    );

       and

         my $t = HTML::Template->new( arrayref => $ref_to_array_of_lines ,
                                      option => 'value'
                                    );

       These initialize the template from in-memory resources.  In almost every case you'll want
       to use the filename parameter.  If you're worried about all the disk access from reading a
       template file just use mod_perl and the cache option detailed below.

       You can also read the template from an already opened filehandle, either traditionally as
       a glob or as a FileHandle:

         my $t = HTML::Template->new( filehandle => *FH, option => 'value');

       The four new() calling methods can also be accessed as below, if you prefer.

         my $t = HTML::Template->new_file('file.tmpl', option => 'value');

         my $t = HTML::Template->new_scalar_ref($ref_to_template_text,
                                               option => 'value');

         my $t = HTML::Template->new_array_ref($ref_to_array_of_lines,
                                              option => 'value');

         my $t = HTML::Template->new_filehandle($fh,
                                              option => 'value');

       And as a final option, for those that might prefer it, you can call new as:

         my $t = HTML::Template->new(type => 'filename',
                                     source => 'file.tmpl');

       Which works for all three of the source types.

       If the environment variable HTML_TEMPLATE_ROOT is set and your filename doesn't begin with
       /, then the path will be relative to the value of $HTML_TEMPLATE_ROOT.  Example - if the
       environment variable HTML_TEMPLATE_ROOT is set to "/home/sam" and I call
       HTML::Template->new() with filename set to "sam.tmpl", the HTML::Template will try to open
       "/home/sam/sam.tmpl" to access the template file.  You can also affect the search path for
       files with the "path" option to new() - see below for more information.

       You can modify the Template object's behavior with new().  The options are available:

       Error Detection Options
           ·   die_on_bad_params - if set to 0 the module will let you call
               $template->param(param_name => 'value') even if 'param_name' doesn't exist in the
               template body.  Defaults to 1 in HTML::Template.

               HTML::Template::Pro always use die_on_bad_params => 0.  It currently can't be
               changed, because HTML::Template::Pro can't know whether a parameter is bad until
               it finishes output.

               Note that it is wrapper-only option: it is not implemented in the htmltmplpro C
               library.

           ·   force_untaint - if set to 1 the module will not allow you to set unescaped
               parameters with tainted values. If set to 2 you will have to untaint all
               parameters, including ones with the escape attribute.  This option makes sure you
               untaint everything so you don't accidentally introduce e.g. cross-site-scripting
               (CSS) vulnerabilities. Requires taint mode. Defaults to 0.

               In the original HTML::Template, if the "force_untaint" option is set an error
               occurs if you try to set a value that is tainted in the param() call. In
               HTML::Template::Pro, an error occurs when output is called.

               Note that the tainted value will never be printed; but, to completely suppress
               output, one should use call to output() that returns string, like print
               $tmpl->output(); Then output() will die before it returns the string to print.

               Note that it is wrapper-only perl-specific option: it is not implemented in the
               htmltmplpro C library.

           ·   strict - if set to 0 the module will allow things that look like they might be
               TMPL_* tags to get by without dieing.  Example:

                  <TMPL_HUH NAME=ZUH>

               Would normally cause an error, but if you call new with strict => 0,
               HTML::Template will ignore it.  Defaults to 1.

               HTML::Template::Pro always implies strict => 0.

       Caching Options
           HTML::Template use many caching options such as cache, shared_cache, double_cache,
           blind_cache, file_cache, file_cache_dir, file_cache_dir_mode, double_file_cache to
           cache preparsed html templates.

           Since HTML::Template::Pro parses and outputs templates at once, it silently ignores
           those options.

       Filesystem Options
           ·   path - you can set this variable with a list of paths to search for files
               specified with the "filename" option to new() and for files included with the
               <TMPL_INCLUDE> tag.  This list is only consulted when the filename is relative.
               The HTML_TEMPLATE_ROOT environment variable is always tried first if it exists.
               Also, if HTML_TEMPLATE_ROOT is set then an attempt will be made to prepend
               HTML_TEMPLATE_ROOT onto paths in the path array.  In the case of a <TMPL_INCLUDE>
               file, the path to the including file is also tried before path is consulted.

               Example:

                  my $template = HTML::Template->new( filename => 'file.tmpl',
                                                      path => [ '/path/to/templates',
                                                                '/alternate/path'
                                                              ]
                                                     );

               NOTE: the paths in the path list must be expressed as UNIX paths, separated by the
               forward-slash character ('/').

           ·   search_path_on_include - if set to a true value the module will search from the
               top of the array of paths specified by the path option on every <TMPL_INCLUDE> and
               use the first matching template found.  The normal behavior is to look only in the
               current directory for a template to include.  Defaults to 0.

       Debugging Options
           ·   debug - if set to 1 the module will write random debugging information to STDERR.
               Defaults to 0.

           ·   HTML::Template use many cache debug options such as stack_debug, cache_debug,
               shared_cache_debug, memory_debug.  Since HTML::Template::Pro parses and outputs
               templates at once, it silently ignores those options.

       Miscellaneous Options
           ·   associate - this option allows you to inherit the parameter values from other
               objects.  The only requirement for the other object is that it have a "param()"
               method that works like HTML::Template's "param()".  A good candidate would be a
               CGI.pm query object.  Example:

                 my $query = new CGI;
                 my $template = HTML::Template->new(filename => 'template.tmpl',
                                                    associate => $query);

               Now, "$template->output()" will act as though

                 $template->param('FormField', $cgi->param('FormField'));

               had been specified for each key/value pair that would be provided by the
               "$cgi->param()" method.  Parameters you set directly take precedence over
               associated parameters.

               You can specify multiple objects to associate by passing an anonymous array to the
               associate option.  They are searched for parameters in the order they appear:

                 my $template = HTML::Template->new(filename => 'template.tmpl',
                                                    associate => [$query, $other_obj]);

               NOTE: If the option case_sensitive => 0, the parameter names are matched in a
               case-insensitive manner.  If you have two parameters in a CGI object like 'NAME'
               and 'Name' one will be chosen randomly by associate.  This behavior can be changed
               by setting option case_sensitive to 1.

           ·   case_sensitive - setting this option to true causes HTML::Template to treat
               template variable names case-sensitively.  The following example would only set
               one parameter without the "case_sensitive" option:

                 my $template = HTML::Template->new(filename => 'template.tmpl',
                                                    case_sensitive => 1);
                 $template->param(
                   FieldA => 'foo',
                   fIELDa => 'bar',
                 );

               This option defaults to off to keep compatibility with HTML::Template.
               Nevertheless, setting case_sensitive => 1 is encouraged, because it significantly
               improves performance.

               If case_sensitive is set to 0, the perl wrapper is forced to lowercase keys in
               every hash it will find in "param" tree, which is sometimes an expensive
               operation. To avoid this, set case_sensitive => 1.

               If case conversion is necessary, there is an alternative lightweight option
               tmpl_var_case, which is HTML::Template::Pro specific.

               Note that case_sensitive is wrapper-only option: it is not implemented in the
               htmltmplpro C library.

           ·   tmpl_var_case - this option is similar to case_sensitive, but is implemented
               directly in the htmltmplpro C library.  Instead of converting keys in every hash
               of "param" tree, it converts the name of variable.

               For example, in case of <tmpl_var name="CamelCaseName"> setting tmpl_var_case =
               ASK_NAME_AS_IS | ASK_NAME_LOWERCASE | ASK_NAME_UPPERCASE will cause
               HTML::Template::Pro to look into "param" tree for 3 names: CamelCaseName,
               camelcasename, and CAMELCASENAME.

               By default, the name is asked "as is".

           ·   loop_context_vars - when this parameter is set to true (it is false by default)
               four loop context variables are made available inside a loop: __first__, __last__,
               __inner__, __odd__.  They can be used with <TMPL_IF>, <TMPL_UNLESS> and
               <TMPL_ELSE> to control how a loop is output.

               In addition to the above, a __counter__ var is also made available when loop
               context variables are turned on.

               Example:

                  <TMPL_LOOP NAME="FOO">
                     <TMPL_IF NAME="__first__">
                       This only outputs on the first pass.
                     </TMPL_IF>

                     <TMPL_IF NAME="__odd__">
                       This outputs every other pass, on the odd passes.
                     </TMPL_IF>

                     <TMPL_UNLESS NAME="__odd__">
                       This outputs every other pass, on the even passes.
                     </TMPL_UNLESS>

                     <TMPL_IF NAME="__inner__">
                       This outputs on passes that are neither first nor last.
                     </TMPL_IF>

                     This is pass number <TMPL_VAR NAME="__counter__">.

                     <TMPL_IF NAME="__last__">
                       This only outputs on the last pass.
                     </TMPL_IF>
                  </TMPL_LOOP>

               One use of this feature is to provide a "separator" similar in effect to the perl
               function join().  Example:

                  <TMPL_LOOP FRUIT>
                     <TMPL_IF __last__> and </TMPL_IF>
                     <TMPL_VAR KIND><TMPL_UNLESS __last__>, <TMPL_ELSE>.</TMPL_UNLESS>
                  </TMPL_LOOP>

               Would output (in a browser) something like:

                 Apples, Oranges, Brains, Toes, and Kiwi.

               Given an appropriate "param()" call, of course.  NOTE: A loop with only a single
               pass will get both __first__ and __last__ set to true, but not __inner__.

               NOTE: in the original HTML::Template with case_sensitive = 1 and loop_context_vars
               the special loop variables are available in lower-case only.  In
               HTML::Template::Pro they are recognized regardless of case.

           ·   no_includes - set this option to 1 to disallow the <TMPL_INCLUDE> tag in the
               template file.  This can be used to make opening untrusted templates slightly less
               dangerous.  Defaults to 0.

           ·   max_includes - set this variable to determine the maximum depth that includes can
               reach.  Set to 10 by default.  Including files to a depth greater than this value
               causes an error message to be displayed.  Set to 0 to disable this protection.

           ·   global_vars - normally variables declared outside a loop are not available inside
               a loop.  This option makes <TMPL_VAR>s like global variables in Perl - they have
               unlimited scope.  This option also affects <TMPL_IF> and <TMPL_UNLESS>.

               Example:

                 This is a normal variable: <TMPL_VAR NORMAL>.<P>

                 <TMPL_LOOP NAME=FROOT_LOOP>
                    Here it is inside the loop: <TMPL_VAR NORMAL><P>
                 </TMPL_LOOP>

               Normally this wouldn't work as expected, since <TMPL_VAR NORMAL>'s value outside
               the loop is not available inside the loop.

               The global_vars option also allows you to access the values of an enclosing loop
               within an inner loop.  For example, in this loop the inner loop will have access
               to the value of OUTER_VAR in the correct iteration:

                  <TMPL_LOOP OUTER_LOOP>
                     OUTER: <TMPL_VAR OUTER_VAR>
                       <TMPL_LOOP INNER_LOOP>
                          INNER: <TMPL_VAR INNER_VAR>
                          INSIDE OUT: <TMPL_VAR OUTER_VAR>
                       </TMPL_LOOP>
                  </TMPL_LOOP>

               NOTE: "global_vars" is not "global_loops" (which does not exist).  That means that
               loops you declare at one scope are not available inside other loops even when
               "global_vars" is on.

           ·   path_like_variable_scope - this option switches on a Shigeki Morimoto extension to
               HTML::Template::Pro that allows access to variables that are outside the current
               loop scope using path-like expressions.

               Example: {{{ <TMPL_LOOP NAME=class>
                 <TMPL_LOOP NAME=person>
                   <TMPL_VAR NAME="../teacher_name">  <!-- access to class.teacher_name -->
                   <TMPL_VAR NAME="name">
                   <TMPL_VAR NAME="/top_level_value"> <!-- access to top level value -->
                   <TMPL_VAR NAME="age">
                     <TMPL_LOOP NAME="../../school">  <!-- enter loop before accessing its vars
               -->
                       <TMPL_VAR NAME="school_name">  <!-- access to [../../]school.school_name
               -->
                     </TMPL_LOOP>
                 </TMPL_LOOP> </TMPL_LOOP> }}}

           ·   filter - this option allows you to specify a filter for your template files.  A
               filter is a subroutine that will be called after HTML::Template reads your
               template file but before it starts parsing template tags.

               In the most simple usage, you simply assign a code reference to the filter
               parameter.  This subroutine will receive a single argument - a reference to a
               string containing the template file text.  Here is an example that accepts
               templates with tags that look like "!!!ZAP_VAR FOO!!!" and transforms them into
               HTML::Template tags:

                  my $filter = sub {
                    my $text_ref = shift;
                    $$text_ref =~ s/!!!ZAP_(.*?)!!!/<TMPL_$1>/g;
                  };

                  # open zap.tmpl using the above filter
                  my $template = HTML::Template->new(filename => 'zap.tmpl',
                                                     filter => $filter);

               More complicated usages are possible.  You can request that your filter receive
               the template text as an array of lines rather than as a single scalar.  To do that
               you need to specify your filter using a hash-ref.  In this form you specify the
               filter using the "sub" key and the desired argument format using the "format" key.
               The available formats are "scalar" and "array".  Using the "array" format will
               incur a performance penalty but may be more convenient in some situations.

                  my $template = HTML::Template->new(filename => 'zap.tmpl',
                                                     filter => { sub => $filter,
                                                                 format => 'array' });

               You may also have multiple filters.  This allows simple filters to be combined for
               more elaborate functionality.  To do this you specify an array of filters.  The
               filters are applied in the order they are specified.

                  my $template = HTML::Template->new(filename => 'zap.tmpl',
                                                     filter => [
                                                          { sub => \&decompress,
                                                            format => 'scalar' },
                                                          { sub => \&remove_spaces,
                                                            format => 'array' }
                                                       ]);

               The specified filters will be called for any TMPL_INCLUDEed files just as they are
               for the main template file.

           ·   default_escape - Set this parameter to "HTML", "URL" or "JS" and HTML::Template
               will apply the specified escaping to all variables unless they declare a different
               escape in the template.

   param()
       "param()" can be called in a number of ways

       1) To return a list of parameters in the template :
          ( this features is distinct in HTML::Template::Pro:
          it returns a list of parameters _SET_ after new() )

          my @parameter_names = $self->param();

       2) To return the value set to a param :

          my $value = $self->param('PARAM');

       3) To set the value of a parameter :

             # For simple TMPL_VARs:
             $self->param(PARAM => 'value');

             # with a subroutine reference that gets called to get the value
             # of the scalar.  The sub will receive the template object as a
             # parameter.
             $self->param(PARAM => sub { return 'value' });

             # And TMPL_LOOPs:
             $self->param(LOOP_PARAM =>
                          [
                           { PARAM => VALUE_FOR_FIRST_PASS, ... },
                           { PARAM => VALUE_FOR_SECOND_PASS, ... }
                           ...
                          ]
                         );

       4) To set the value of a a number of parameters :

            # For simple TMPL_VARs:
            $self->param(PARAM => 'value',
                         PARAM2 => 'value'
                        );

             # And with some TMPL_LOOPs:
             $self->param(PARAM => 'value',
                          PARAM2 => 'value',
                          LOOP_PARAM =>
                          [
                           { PARAM => VALUE_FOR_FIRST_PASS, ... },
                           { PARAM => VALUE_FOR_SECOND_PASS, ... }
                           ...
                          ],
                          ANOTHER_LOOP_PARAM =>
                          [
                           { PARAM => VALUE_FOR_FIRST_PASS, ... },
                           { PARAM => VALUE_FOR_SECOND_PASS, ... }
                           ...
                          ]
                         );

       5) To set the value of a a number of parameters using a hash-ref :

             $self->param(
                          {
                             PARAM => 'value',
                             PARAM2 => 'value',
                             LOOP_PARAM =>
                             [
                               { PARAM => VALUE_FOR_FIRST_PASS, ... },
                               { PARAM => VALUE_FOR_SECOND_PASS, ... }
                               ...
                             ],
                             ANOTHER_LOOP_PARAM =>
                             [
                               { PARAM => VALUE_FOR_FIRST_PASS, ... },
                               { PARAM => VALUE_FOR_SECOND_PASS, ... }
                               ...
                             ]
                           }
                          );

   clear_params()
       Sets all the parameters to undef.  Useful internally, if nowhere else!

   output()
       output() returns the final result of the template.  In most situations you'll want to
       print this, like:

          print $template->output();

       When output is called each occurrence of <TMPL_VAR NAME=name> is replaced with the value
       assigned to "name" via "param()".  If a named parameter is unset it is simply replaced
       with ''.  <TMPL_LOOPS> are evaluated once per parameter set, accumulating output on each
       pass.

       Calling output() is guaranteed not to change the state of the Template object, in case you
       were wondering.  This property is mostly important for the internal implementation of
       loops.

       You may optionally supply a filehandle to print to automatically as the template is
       generated.  This may improve performance and lower memory consumption.  Example:

          $template->output(print_to => *STDOUT);

       The return value is undefined when using the "print_to" option.

   query()
       This method is not supported in HTML::Template::Pro.

DISTINCTIONS AND INCOMPATIBILITIES

       The main reason for small incompatibilities between HTML::Template and HTML::Template::Pro
       is the fact that HTML::Template builds parsed tree of template before anything else. So it
       has an additional information which HTML::Template::Pro obtains during output.

       In cases when HTML::Template dies, such as no_includes, bad syntax of template,
       max_includes and so on, HTML::Template::Pro issues warning to STDERR and continue.

   new()
       the following options are not supported in HTML::Template::Pro:

        vanguard_compatibility_mode.

       The options die_on_bad_params and strict are ignored.  HTML::Template::Pro behaves itself
       as HTML::Template called with
        die_on_bad_params => 0, strict => 0.

       It currently can't be changed, because HTML::Template::Pro can't know whether a parameter
       is bad before it start output.  This may change in future releases.

       To keep backward compatibility with HTML::Template, you should explicitly call its new()
       with die_on_bad_params => 0, strict => 0.

   query()
       This method is not supported in HTML::Template::Pro.

   param()
       param() without arguments should return a list of parameters in the template.  In
       HTML::Template::Pro it returns a list of parameters set after new().

BUGS

       With case_sensitive and loop_context_vars the special loop variables should be available
       in lower-case only.

       associate is case_sensitive inside loops.

       When submitting bug reports, be sure to include full details, including the VERSION of the
       module, a test script and a test template demonstrating the problem!

EXPR: DEFINING NEW FUNCTIONS

       To define a new function, pass a "functions" option to new:

         $t = HTML::Template::Pro->new(filename => 'foo.tmpl',
                                        functions =>
                                          { func_name => \&func_handler });
       or

         $t = HTML::Template::Expr->new(filename => 'foo.tmpl',
                                        functions =>
                                          { func_name => \&func_handler });

       Or, you can use "register_function" class method to register the function globally:

         HTML::Template::Pro->register_function(func_name => \&func_handler);
       or
         HTML::Template::Expr->register_function(func_name => \&func_handler);

       You provide a subroutine reference that will be called during output.  It will receive as
       arguments the parameters specified in the template.  For example, here's a function that
       checks if a directory exists:

         sub directory_exists {
           my $dir_name = shift;
           return 1 if -d $dir_name;
           return 0;
         }

       If you call HTML::Template::Expr->new() with a "functions" arg:

         $t = HTML::Template::Expr->new(filename => 'foo.tmpl',
                                        functions => {
                                           directory_exists => \&directory_exists
                                        });

       Then you can use it in your template:

         <tmpl_if expr="directory_exists('/home/sam')">

       This can be abused in ways that make my teeth hurt.

   register_function() extended usage (HTML::Template::Pro specific)
       "register_function()" can be called in a number of ways

       1) To fetch the names of registered functions in the template:

       ·   if "register_function()" was called in a newly created object it returns a

              list of function's that set _after_ or _in_ new():

              my @registered_functions_names = $self->register_function();

       ·   in global context "register_function()" will return a list of _ALL_
              avalible function's

              my @all_avalible_functions_names =
           HTML::Template::Pro->register_function();

           2) To fetching the function by name:

              my $function = $self->register_function('FUNCTION_NAME');

           3) To set a new function:

               # Set function, that can be called in templates, wich are processed
               # by the current object:
               $self->register_function(foozicate => sub { ... });

               # Set global function:
               HTML::Template::Pro->register_function(barify    => sub { ... });

       for details of "how to defined a function" see in "EXPR: DEFINING NEW FUNCTIONS".

EXPR MOD_PERL TIP

       "register_function" class method can be called in mod_perl's startup.pl to define widely
       used common functions to HTML::Template::Expr. Add something like this to your startup.pl:

         use HTML::Template::Pro;

         HTML::Template::Pro->register_function(foozicate => sub { ... });
         HTML::Template::Pro->register_function(barify    => sub { ... });
         HTML::Template::Pro->register_function(baznate   => sub { ... });

EXPR CAVEATS

       HTML::Template::Pro does not forces the HTML::Template global_vars option to be set,
       whereas currently HTML::Template::Expr does.  Anyway, this also will hopefully go away in
       a future version of HTML::Template::Expr, so if you need global_vars in your templates
       then you should set it explicitly.
