=head1 DESCRIPTION
The Template::Alloy::HTE role provides syntax and interface support for
the HTML::Template and HTML::Template::Expr modules.
Provides for extra or extended features that may not be as commonly used.
This module should not normally be used by itself.
See the Template::Alloy documentation for configuration and other parameters.
=head1 HOW IS Template::Alloy DIFFERENT FROM HTML::Template
Alloy can use the same base template syntax and configuration items as HTE
and HT. The internals of Alloy were written to support TT3, but were
general enough to be extended to support HTML::Template as well. The result
is HTML::Template::Expr compatible syntax, with Alloy speed and a wide range
of additional features.
The TMPL_VAR, TMPL_IF, TMPL_ELSE, TMPL_UNLESS, TMPL_LOOP, and TMPL_INCLUDE
all work identically to HTML::Template.
=over 4
=item
Added support for other TT3 directives and for TT style "dot notation."
<TMPL_SET a = "bar">
<TMPL_SET b = [1 .. 25]>
<TMPL_SET foo = PROCESS 'filename.tt'>
<TMPL_GET foo> # similar to <TMPL_VAR NAME="foo">
<TMPL_GET b.3>
<TMPL_GET my.nested.chained.variable.1>
<TMPL_GET my_var | html>
<TMPL_USE foo = DBI(db => ...)>
<TMPL_CALL foo.connect>
Any of the TT directives can be used in HTML::Template documents.
For many die-hard HTML::Template fans, it is probably quite scary to
be providing all of the TT functionality. All of the extended
TT functionality can be disabled by setting the NO_TT configuration
item. The NO_TT configuration is automatically set if the SYNTAX is
set to "ht" and the output method is called.
=item
There is an ELSIF!!!
<TMPL_IF foo>
FOO
<TMPL_ELSIF bar>
BAR
<TMPL_ELSE>
Done then
</TMPL_IF>
=item
Added CHOMP capabilities (PRE_CHOMP and POST_CHOMP)
Foo
<~TMPL_VAR EXPR="1+2"~>
Bar
Prints Foo3Bar
=item
Added INTERPOLATE capability
<TMPL_SET foo = 'FOO'>
<TMPL_CONFIG INTERPOLATE => 1>
$foo <TMPL_GET foo> ${ 1 + 2 }
Prints
FOO FOO 3
=item
Allow for HTML::Template templates to include TT style templates.
<TMPL_CONFIG SYNTAX => 'tt3'>
<TMPL_INCLUDE "filename.tt">
=item
Allow for Expr parsing to follow proper precedence rules.
<TMPL_VAR EXPR="1 + 2 * 3">
Properly prints 7.
=item
Uses all of the caching and opcode tree optimizations provided by
Template::Alloy and Template::Alloy::XS.
=item
Alloy does not provide the query method from HTML::Template. This
is because parsing of the document is delayed until the output
method is called, and because Alloy supports TT style chained
variables which often are not resolvable until run time.
=back
=head1 UNSUPPORTED HT CONFIGURATION
=over 4
=item die_on_bad_params
Alloy does not resolve variables until the template is output.
=item force_untaint
=item strict
Alloy is strict on parsing HT documents.
=item shared_cache, double_cache
Alloy doesn't have shared caching. Yet.
=item search_path_on_include
Alloy will check the full path array on each include.
=item debug items
The HTML::Template style options are included here, but you
can use the TT style DEBUG and DUMP directives to do introspection.
=item max_includes
Alloy uses TT's recursion protection.
=item filter
Alloy doesn't offer these.
=back
=head1 ROLE METHODS
=over 4
=item C<register_function>
Defines a new function for later use as text vmethod or top level function.
=item C<clear_param>
Empties the parameter list.
=item C<query>
Not supported.
=item C<new_file>
Creates a new object that will process the passed file.
$obj = Template::Alloy->new_file("my/file.hte");
=item C<new_scalar_ref>
Creates a new object that will process the passed scalar ref.
$obj = Template::Alloy->new_scalar_ref(\"some template text");
=item C<new_array_ref>
New object that will process the passed array (each item represents a line).
$obj = Template::Alloy->new_array_ref(\@array);
=item C<new_filehandle>
$obj = Template::Alloy->new_filehandle(\*FH);
=item C<parse_tree_hte>
Called by parse_tree when syntax is set to ht or hte. Parses for tags HTML::Template style.
=item C<param>
See L<Template::Alloy>.
=item C<output>
See L<Template::Alloy>.
