+
+## [4.0.0-rc.0] - 2021-10-13
+
+### Added
+- You can now use `$smarty->muteUndefinedOrNullWarnings()` to activate convert warnings about undefined or null template vars to notices when running PHP8
+
+### Changed
+- Switch CI from Travis to Github CI
+- Updated unit tests to avoid skipped and risky test warnings
+
+### Removed

+- Dropped support for php asp tags in templates (removed from php since php7.0)
+- Dropped deprecated API calls that where only accessible through SmartyBC
+- Dropped support for {php} and {include_php} tags and embedded PHP in templates. Embedded PHP will now be passed through as is.
+- Removed all PHP_VERSION_ID and compare_version checks and conditional code blocks that are now no longer required
+- Dropped deprecated SMARTY_RESOURCE_CHAR_SET and SMARTY_RESOURCE_DATE_FORMAT constants
+- Dropped deprecated Smarty::muteExpectedErrors and Smarty::unmuteExpectedErrors API methods
+- Dropped deprecated $smarty->getVariable() method. Use $smarty->getTemplateVars() instead.
+- $smarty->registerResource() no longer accepts an array of callback functions

+
+### Security
+- Prevent access to `$smarty.template_object` in sandbox mode. This addresses CVE-2021-26119.

-
-Since 3.1.28 you can mix inheritance by extends resource with the {extends} tag.
-A template called by extends resource can extend a subtemplate or chain buy the {extends} tag.
-Since 3.1.31 this feature can be turned off by setting the new Smarty property Smarty::$extends_recursion to false.
-
-3.1.28
-Starting with version 3.1.28 template inheritance is no longer a compile time process.
-All {block} tag parent/child relations are resolved at run time.
-This does resolve all known existing restrictions (see below).
-
-The $smarty::$inheritance_merge_compiled_includes property has been removed.
-Any access to it is ignored.
-
-New features:
-
-Any code outside root {block} tags in child templates is now executed but any output will be ignored.
-
-   {extends 'foo.tpl'}
-   {$bar = 'on'}           // assigns variable $bar seen in parent templates
-   {block 'buh'}{/block}
-
-   {extends 'foo.tpl'}
-   {$bar}           // the output of variable bar is ignored
-   {block 'buh'}{/block}

-   {/block}
-
-Starting with 3.1.28 you can mix inheritance by extends resource with the {extends} tag.
-A template called by extends resource can extend a subtemplate or chain buy the {extends} tag.
-
-NOTE There is a BC break. If you used the extends resource {extends} tags have been ignored.
-
-THE FOLLOWING RESTRICTIONS ARE NO LONGER EXISTING:
-In Smarty 3.1 template inheritance is a compile time process. All the extending of {block} tags
-is done at compile time and the parent and child templates are compiled in a single compiled template.
-{include} subtemplate could also {block} tags. Such subtemplate could not compiled by it's own because
-it could be used in other context where the {block} extended with a different result. For that reasion
-the compiled code of {include} subtemplates gets also merged in compiled inheritance template.
-
-Merging the code into a single compile template has some drawbacks.
-1. You could not use variable file names in {include} Smarty would use the {include} of compilation time.
-2. You could not use individual compile_id in {include}
-3. Separate caching of subtemplate was not possible
-4. Any change of the template directory structure between calls was not necessarily seen.
-
-Starting with 3.1.15 some of the above conditions got checked and resulted in an exception. It turned out
-that a couple of users did use some of above and now got exceptions.
-
-To resolve this starting with 3.1.16 there is a new configuration parameter $inheritance_merge_compiled_includes.
-For most backward compatibility its default setting is true.
-With this setting all {include} subtemplate will be merge into the compiled inheritance template, but the above cases
-could be rejected by exception.
-
-
-If $smarty->inheritance_merge_compiled_includes = false; {include} subtemplate will not be merged.You must now manually merge all {include} subtemplate which do contain {block} tags. This is done by setting the "inline" option.
-{include file='foo.bar' inline}
-
-1. In case of a variable file name like {include file=$foo inline} you must use the variable in a compile_id  $smarty->compile_id = $foo;
-2. If you use individual compile_id in {include file='foo.tpl' compile_id=$bar inline} it must be used in the   global compile_id as well  $smarty->compile_id = $bar;
-3. If call templates with different template_dir configurations and a parent could same named child template from different folders
-   you must make the folder name part of the compile_id.

-This file contains a brief description of new features which have been added to Smarty 3.1
-
-Smarty 3.1.33-dev
-    Variable capture name in Smarty special variable
-    ================================================
-    {$smarty.capture.$foo} can now be used to access the content of a named
-     capture block
-
-Smarty 3.1.32
-    New tags for inheritance parent and child
-    =========================================
-    {parent}  == {$smarty.block.parent}
-    {child}  == {$smarty.block.child}
-    Both tags support the assign attribute like
-    {child assign=foo}
-
-    Deprecate functions Smarty::muteExpectedErrors() and Smarty::unmuteExpectedErrors()
-    ===================================================================================
-    These functions to start a special error handler are no longer needed as Smarty does
-    no longer use error suppression like @filemtime().
-    For backward compatibility the functions still can be called.
-
-    Using literals containing Smarty's left and right delimiter
-    ===========================================================
-    New Methods
-        $smarty->setLiterals(array $literals)
-        $smarty->addLiterals(array $literals)
-    to define literals  containing Smarty delimiter. This can avoid the need for extreme usage
-    of {literal} {/literal} tags.
-    A) Treat '{{' and '}}' as literal
-    If Smarty::$auto_literal is enabled
-        {{ foo }}
-    will be treated now as literal. (This does apply for any number of delimiter repeatations).
-    However {{foo}} is not an literal but will be interpreted as a recursive Smarty tag.
-    If you use
-         $smarty->setLiterals(array('{{','}}'));
-         {{foo}}  is now a literal as well.
-    NOTE: In the last example nested Smarty tags starting with '{{' or ending with '}}' will not
-    work any longer, but this should be very very raw occouring restriction.
-    B) Example 2
-    Assume your delimiter are '<-' , '->' and '<--' , '-->' shall be literals 
-          $smarty->setLiterals(array('<--','-->'));
-
-
-    The capture buffers can now be accessed as array
-    ================================================
-    {capture name='foo'}
-        bah
-     {\capture}
-     {capture name='buh'}
-       blar
-     {\capture}
-     {foreach $smarty.capture as $name => $buffer}
-        ....
-      {/foreach}
-
-Smarty 3.1.31
-    New tags for inheritance parent and child
-    =========================================
-    {block_parent}  == {$smarty.block.parent}
-    {block_child}  == {$smarty.block.child}
-
-Smarty 3.1.30
-
-    Loop optimization {foreach} and {section}
-    =========================================
-    Smarty does optimize the {foreach} and {section} loops by removing code for not needed loop
-    properties.
-    The compiler collects needed properties by scanning the current template for $item@property,
-    $smarty.foreach.name.property and $smarty.section.name.property.
-    The compiler does not know if additional properties will be needed outside the current template scope.
-    Additional properties can be generated by adding them with the property attribute.
-
-    Example:
-        index.tpl
-        {foreach $from as $item properties=[iteration, index]}
-            {include 'sub.tpl'}
-            {$item.total}
-        {/foreach}
-
-        sub.tpl
-        {$item.index} {$item.iteration} {$item.total}
-
-    In above example code for the 'total' property is automatically generated as $item.total is used in
-    index.tpl. Code for 'iteration' and 'index' must be added with properties=[iteration, index].
-
-    New tag {make_nocache}
-    ======================
-    Syntax: {make_nocache $foo}
-
-    This tag makes a variable which does exists normally only while rendering the compiled template
-    available in the cached template for use in not cached expressions.
-
-    Expample:
-        {foreach from=$list item=item}
-            <li>{$item.name} {make_nocache $item}{if $current==$item.id} ACTIVE{/if}</li>
-        {/foreach}
-
-    The {foreach} loop is rendered while processing the compiled template, but $current is a nocache
-    variable. Normally the {if $current==$item.id} would fail as the $item variable is unknown in the     cached template. {make_nocache $item} does make the current $item value known in thee cached template.
-
-    {make_nocache} is ignored when caching is disabled or the variable does exists as nocache variable.
-
-    NOTE: if the variable value does contain objects these must have the __set_state method implemented.
-
-
-    Scope Attributes
-    ================
-    The scope handling has been updated to cover all cases of variable assignments in templates.
-
-    The tags {assign}, {append} direct assignments like {$foo = ...}, {$foo[...]= ...} support
-    the following optional scope attributes:
-    scope='parent'    - the variable will be assigned in the current template and if the template
-                        was included by {include} the calling template
-    scope='tpl_root'  - the variable will be assigned in the outermost root template called by $smarty->display()
-                        or $smarty->fetch() and is bubbled up all {include} sub-templates to the current template.
-    scope='smarty'    - the variable will be assigned in the Smarty object and is bubbled up all {include} sub-templates
-                        to the current template.
-    scope='global'    - the variable will be assigned as Smarty object global variable and is bubbled up all {include}
-                        sub-templates to the current template.
-    scope='root'      - the variable will be assigned if a data object was used for variable definitions in the data
-                        object or in the Smarty object otherwise and is bubbled up all {include} sub-templates to the
-                        current template.
-    scope='local'     - this scope has only a meaning if the tag is called within a template {function}.
-                        The variable will be assigned in the local scope of the template function and the
-                        template which did call the template function.
-
-
-    The {config_load} tag supports all of the above except the global scope.
-
-    The scope attribute can be used also with the {include} tag.
-    Supported scope are parent, tpl_root, smarty, global and root.
-    A scope used together with the {include} tag will cause that with some exceptions any variable
-    assignment within that sub-template will update/assign the variable in other scopes according
-    to the above rules. It does include also variables assigned by plugins, tags supporting the assign=foo     attribute and direct assignments in {if} and {while} like {if $foo=$bar}.
-    Excluded are the key and value variables of {foreach}, {for} loop variables , variables passed by attributes
-    in {include} and direct increments/decrements like {$foo++}, {$foo--}
-
-    Note: The scopes should be used only to the extend really need. If a variable value assigned in an included
-          sub-template should be returned to the calling sub-template just use {$foo='bar' scope='parent'}.
-          Use scopes only with variables for which it's realy needed. Avoid general scope settings with the
-          {include} tag as it can have a performance impact.
-
-     The {assign}, {append}, {config_load} and {$foo...=...} tags have a new option flag 'noscope'.Thi
-     Example: {$foo='bar' noscope}  This will assign $foo only in the current template and any scope settings
-               at {include} is ignored.
-
-
-    Caching
-    =======
-    Caching does now observe the template_dir setting and will create separate cache files if required
-
-    Compiled Templates
-    ==================
-    The template_dir setting is now encoded in the uid of the file name.
-    The content of the compiled template may depend on the template_dir search order
-    {include .... inline} is used or $smarty->merge_compiled_includes is enabled
-
-    APC
-    ===
-    If APC is enabled force an apc_compile_file() when compiled or cached template was updated
-
-Smarty 3.1.28
-
-    OPCACHE
-    =======
-    Smarty does now invalidate automatically updated and cleared compiled or cached template files in OPCACHE.
-    Correct operation is no longer dependent on OPCACHE configuration settings.
-
-    Template inheritance
-    ====================
-    Template inheritance is now processed in run time.
-    See the INHERITANCE_RELEASE_NOTES
-
-    Modifier regex_replace
-    ======================
-    An optional limit parameter was added
-
-    fetch() and display()
-    =====================
-    The fetch() and display() methods of the template object accept now optionally the same parameter
-    as the corresponding Smarty methods to get the content of another template.
-    Example:
-        $template->display();           Does display template of template object
-        $template->display('foo.tpl');  Does display template 'foo.bar'     
-        
-    File: resource
-    ==============
-    Multiple template_dir entries can now be selected  by a comma separated list of indices.
-    The template_dir array is searched in the order of the indices. (Could be used to change the default search order)
-    Example:
-        $smarty->display('[1],[0]foo.bar');
-
-    Filter support
-    ==============
-    Optional filter names
-      An optional filter name was added to $smarty->registerFilter(). It can be used to unregister a filter by name.
-      - $smarty->registerFilter('output', $callback, 'name');
-        $smarty->unregister('output', 'name');
-
-    Closures
-      $smarty->registerFilter() does now accept closures.
-      - $smarty->registerFilter('pre', function($source) {return $source;});
-      If no optional filter name was specified it gets the default name 'closure'.
-      If you register multiple closures register each with a unique filter name.
-      - $smarty->registerFilter('pre', function($source) {return $source;}, 'closure_1');
-      - $smarty->registerFilter('pre', function($source) {return $source;}, 'closure_2');
-
-
-Smarty 3.1.22
-
-    Namespace support within templates
-    ==================================
-    Within templates you can now use namespace specifications on:
-     - Constants                like    foo\bar\FOO
-     - Class names              like    foo\bar\Baz::FOO, foo\bar\Baz::$foo, foo\bar\Baz::foo()
-     - PHP function names       like    foo\bar\baz()
-
-    Security
-    ========
-    - disable special $smarty variable -
-    The Smarty_Security class has the new property $disabled_special_smarty_vars.
-    It's an array which can be loaded with the $smarty special variable names like
-    'template_object', 'template', 'current_dir' and others which will be disabled.
-    Note: That this security check is performed at compile time.
-
-    - limit template nesting -
-    Property $max_template_nesting of Smarty_Security does set the maximum template nesting level.
-    The main template is level 1. The nesting level is checked at run time. When the maximum will be exceeded
-    an Exception will be thrown. The default setting is 0 which does disable this check.
-
-    - trusted static methods -
-   The Smarty_Security class has the new property $trusted_static_methods to restrict access to static methods.
-   It's an nested array of trusted class and method names.
-         Format:
-         array (
-                    'class_1' => array('method_1', 'method_2'), // allowed methods
-                    'class_2' => array(),                       // all methods of class allowed
-               )
-   To disable access for all methods of all classes set $trusted_static_methods = null;
-   The default value is an empty array() which does enables all methods of all classes, but for backward compatibility
-   the setting of $static_classes will be checked.
-   Note: That this security check is performed at compile time.
-
-    - trusted static properties -
-   The Smarty_Security class has the new property $trusted_static_properties to restrict access to static properties.
-   It's an nested array of trusted class and property names.
-         Format:
-         array (
-                    'class_1' => array('prop_1', 'prop_2'), // allowed properties listed
-                    'class_2' => array(),                   // all properties of class allowed
-                }
-   To disable access for all properties of all classes set $trusted_static_properties = null;
-   The default value is an empty array() which does enables all properties of all classes, but for backward compatibility
-   the setting of $static_classes will be checked.
-   Note: That this security check is performed at compile time.
-
-    - trusted constants .
-   The Smarty_Security class has the new property $trusted_constants to restrict access to constants.
-   It's an array of trusted constant names.
-         Format:
-         array (
-                    'SMARTY_DIR' , // allowed constant
-                }
-   If the array is empty (default) the usage of constants  can be controlled with the
-   Smarty_Security::$allow_constants property (default true)
-
-
-
-    Compiled Templates
-    ==================
-    Smarty does now automatically detects a change of the $merge_compiled_includes and $escape_html
-    property and creates different compiled templates files depending on the setting.

-AN INTRODUCTION TO SMARTY 3
-
-NOTICE FOR 3.1 release:
-
-Please see the SMARTY_3.1_NOTES.txt file that comes with the distribution.
-
-NOTICE for 3.0.5 release:
-
-Smarty now follows the PHP error_reporting level by default. If PHP does not mask E_NOTICE and you try to access an unset template variable, you will now get an E_NOTICE warning. To revert to the old behavior:
-
-$smarty->error_reporting = E_ALL & ~E_NOTICE;
-
-NOTICE for 3.0 release:
-
-IMPORTANT: Some API adjustments have been made between the RC4 and 3.0 release.
-We felt it is better to make these now instead of after a 3.0 release, then have to
-immediately deprecate APIs in 3.1. Online documentation has been updated
-to reflect these changes. Specifically:
-
---- API CHANGES RC4 -> 3.0 ----
-
-$smarty->register->*
-$smarty->unregister->*
-$smarty->utility->*
-$samrty->cache->*
-
-Have all been changed to local method calls such as:
-
-$smarty->clearAllCache()
-$smarty->registerFoo()
-$smarty->unregisterFoo()
-$smarty->testInstall()
-etc.
-
-Registration of function, block, compiler, and modifier plugins have been
-consolidated under two API calls:
-
-$smarty->registerPlugin(...)
-$smarty->unregisterPlugin(...)
-
-Registration of pre, post, output and variable filters have been
-consolidated under two API calls:
-
-$smarty->registerFilter(...)
-$smarty->unregisterFilter(...)
-
-Please refer to the online documentation for all specific changes:
-
-http://www.smarty.net/documentation

----
-
-The Smarty 3 API has been refactored to a syntax geared
-for consistency and modularity. The Smarty 2 API syntax is still supported, but
-will throw a deprecation notice. You can disable the notices, but it is highly
-recommended to adjust your syntax to Smarty 3, as the Smarty 2 syntax must run
-through an extra rerouting wrapper.
-
-Basically, all Smarty methods now follow the "fooBarBaz" camel case syntax. Also,
-all Smarty properties now have getters and setters. So for example, the property
-$smarty->cache_dir can be set with $smarty->setCacheDir('foo/') and can be
-retrieved with $smarty->getCacheDir().
-
-Some of the Smarty 3 APIs have been revoked such as the "is*" methods that were
-just duplicate functions of the now available "get*" methods.
-
-Here is a rundown of the Smarty 3 API:
-
-$smarty->fetch($template, $cache_id = null, $compile_id = null, $parent = null)
-$smarty->display($template, $cache_id = null, $compile_id = null, $parent = null)
-$smarty->isCached($template, $cache_id = null, $compile_id = null)
-$smarty->createData($parent = null)
-$smarty->createTemplate($template, $cache_id = null, $compile_id = null, $parent = null)
-$smarty->enableSecurity()
-$smarty->disableSecurity()
-$smarty->setTemplateDir($template_dir)
-$smarty->addTemplateDir($template_dir)
-$smarty->templateExists($resource_name)
-$smarty->loadPlugin($plugin_name, $check = true)
-$smarty->loadFilter($type, $name)
-$smarty->setExceptionHandler($handler)
-$smarty->addPluginsDir($plugins_dir)
-$smarty->getGlobal($varname = null)
-$smarty->getRegisteredObject($name)
-$smarty->getDebugTemplate()
-$smarty->setDebugTemplate($tpl_name)
-$smarty->assign($tpl_var, $value = null, $nocache = false)
-$smarty->assignGlobal($varname, $value = null, $nocache = false)
-$smarty->assignByRef($tpl_var, &$value, $nocache = false)
-$smarty->append($tpl_var, $value = null, $merge = false, $nocache = false)
-$smarty->appendByRef($tpl_var, &$value, $merge = false)
-$smarty->clearAssign($tpl_var)
-$smarty->clearAllAssign()
-$smarty->configLoad($config_file, $sections = null)
-$smarty->getVariable($variable, $_ptr = null, $search_parents = true, $error_enable = true)
-$smarty->getConfigVariable($variable)
-$smarty->getStreamVariable($variable)
-$smarty->getConfigVars($varname = null)
-$smarty->clearConfig($varname = null)
-$smarty->getTemplateVars($varname = null, $_ptr = null, $search_parents = true)
-$smarty->clearAllCache($exp_time = null, $type = null)
-$smarty->clearCache($template_name, $cache_id = null, $compile_id = null, $exp_time = null, $type = null)
-
-$smarty->registerPlugin($type, $tag, $callback, $cacheable = true, $cache_attr = array())
-
-$smarty->registerObject($object_name, $object_impl, $allowed = array(), $smarty_args = true, $block_methods = array())
-
-$smarty->registerFilter($type, $function_name)
-$smarty->registerResource($resource_type, $function_names)
-$smarty->registerDefaultPluginHandler($function_name)
-$smarty->registerDefaultTemplateHandler($function_name)
-
-$smarty->unregisterPlugin($type, $tag)
-$smarty->unregisterObject($object_name)
-$smarty->unregisterFilter($type, $function_name)
-$smarty->unregisterResource($resource_type)
-
-$smarty->compileAllTemplates($extension = '.tpl', $force_compile = false, $time_limit = 0, $max_errors = null)
-$smarty->clearCompiledTemplate($resource_name = null, $compile_id = null, $exp_time = null)
-$smarty->testInstall()
-
-// then all the getters/setters, available for all properties. Here are a few:
-
-$caching = $smarty->getCaching();      // get $smarty->caching
-$smarty->setCaching(true);             // set $smarty->caching
-$smarty->setDeprecationNotices(false); // set $smarty->deprecation_notices
-$smarty->setCacheId($id);              // set $smarty->cache_id
-$debugging = $smarty->getDebugging();  // get $smarty->debugging
-
-
-FILE STRUCTURE
-
-The Smarty 3 file structure is similar to Smarty 2:
-
-/libs/
-  Smarty.class.php
-/libs/sysplugins/
-  internal.*
-/libs/plugins/
-  function.mailto.php
-  modifier.escape.php
-  ...
-
-A lot of Smarty 3 core functionality lies in the sysplugins directory; you do
-not need to change any files here. The /libs/plugins/ folder is where Smarty
-plugins are located. You can add your own here, or create a separate plugin
-directory, just the same as Smarty 2. You will still need to create your own
-/cache/, /templates/, /templates_c/, /configs/ folders. Be sure /cache/ and
-/templates_c/ are writable.
-
-The typical way to use Smarty 3 should also look familiar:
-
-require('Smarty.class.php');
-$smarty = new Smarty;
-$smarty->assign('foo','bar');
-$smarty->display('index.tpl');
-
-
-However, Smarty 3 works completely different on the inside. Smarty 3 is mostly
-backward compatible with Smarty 2, except for the following items:
-
-*) Smarty 3 is PHP 5 only. It will not work with PHP 4.
-*) The {php} tag is disabled by default. Enable with $smarty->allow_php_tag=true.
-*) Delimiters surrounded by whitespace are no longer treated as Smarty tags.
-   Therefore, { foo } will not compile as a tag, you must use {foo}. This change
-   Makes Javascript/CSS easier to work with, eliminating the need for {literal}.
-   This can be disabled by setting $smarty->auto_literal = false;
-*) The Smarty 3 API is a bit different. Many Smarty 2 API calls are deprecated
-   but still work. You will want to update your calls to Smarty 3 for maximum
-   efficiency.
-
-
-There are many things that are new to Smarty 3. Here are the notable items:
-
-LEXER/PARSER
-============
-
-Smarty 3 now uses a lexing tokenizer for its parser/compiler. Basically, this
-means Smarty has some syntax additions that make life easier such as in-template
-math, shorter/intuitive function parameter options, infinite function recursion,
-more accurate error handling, etc.
-
-
-WHAT IS NEW IN SMARTY TEMPLATE SYNTAX
-=====================================
-
-Smarty 3 allows expressions almost anywhere. Expressions can include PHP
-functions as long as they are not disabled by the security policy, object
-methods and properties, etc. The {math} plugin is no longer necessary but
-is still supported for BC.
-
-Examples:
-{$x+$y}                           will output the sum of x and y.
-{$foo = strlen($bar)}             function in assignment
-{assign var=foo value= $x+$y}     in attributes
-{$foo = myfunct( ($x+$y)*3 )}     as function parameter
-{$foo[$x+3]}                      as array index
-
-Smarty tags can be used as values within other tags.
-Example:  {$foo={counter}+3}
-
-Smarty tags can also be used inside double quoted strings.
-Example:  {$foo="this is message {counter}"}
-
-You can define arrays within templates.
-Examples:
-{assign var=foo value=[1,2,3]}
-{assign var=foo value=['y'=>'yellow','b'=>'blue']}
-Arrays can be nested.
-{assign var=foo value=[1,[9,8],3]}
-
-There is a new short syntax supported for assigning variables.
-Example: {$foo=$bar+2}
-
-You can assign a value to a specific array element. If the variable exists but
-is not an array, it is converted to an array before the new values are assigned.
-Examples:
-{$foo['bar']=1}
-{$foo['bar']['blar']=1}
-
-You can append values to an array. If the variable exists but is not an array,
-it is converted to an array before the new values are assigned.
-Example: {$foo[]=1}
-
-You can use a PHP-like syntax for accessing array elements, as well as the
-original "dot" notation.
-Examples:
-{$foo[1]}             normal access
-{$foo['bar']}
-{$foo['bar'][1]}
-{$foo[$x+$x]}         index may contain any expression
-{$foo[$bar[1]]}       nested index
-{$foo[section_name]}  smarty section access, not array access!
-
-The original "dot" notation stays, and with improvements.
-Examples:
-{$foo.a.b.c}        =>  $foo['a']['b']['c']
-{$foo.a.$b.c}       =>  $foo['a'][$b]['c']        with variable index
-{$foo.a.{$b+4}.c}   =>  $foo['a'][$b+4]['c']       with expression as index
-{$foo.a.{$b.c}}     =>  $foo['a'][$b['c']]         with nested index
-
-note that { and } are used to address ambiguties when nesting the dot syntax.
-
-Variable names themselves can be variable and contain expressions.
-Examples:
-$foo         normal variable
-$foo_{$bar}  variable name containing other variable
-$foo_{$x+$y} variable name containing expressions
-$foo_{$bar}_buh_{$blar}  variable name with multiple segments
-{$foo_{$x}}  will output the variable $foo_1 if $x has a value of 1.
-
-Object method chaining is implemented.
-Example: {$object->method1($x)->method2($y)}
-
-{for} tag added for looping (replacement for {section} tag):
-{for $x=0, $y=count($foo); $x<$y; $x++}  ....  {/for}
-Any number of statements can be used separated by comma as the first
-initial expression at {for}.
-
-{for $x = $start to $end step $step} ... {/for}is in the SVN now .
-You can use also
-{for $x = $start to $end} ... {/for}
-In this case the step value will be automatically 1 or -1 depending on the start and end values.
-Instead of $start and $end you can use any valid expression.
-Inside the loop the following special vars can be accessed:
-$x@iteration = number of iteration
-$x@total = total number of iterations
-$x@first = true on first iteration
-$x@last = true on last iteration
-
-
-The Smarty 2 {section} syntax is still supported.
-
-New shorter {foreach} syntax to loop over an array.
-Example: {foreach $myarray as $var}...{/foreach}
-
-Within the foreach loop, properties are access via:
-
-$var@key            foreach $var array key
-$var@iteration      foreach current iteration count (1,2,3...)
-$var@index          foreach current index count (0,1,2...)
-$var@total          foreach $var array total
-$var@first          true on first iteration
-$var@last           true on last iteration
-
-The Smarty 2 {foreach} tag syntax is still supported.
-
-NOTE: {$bar[foo]} still indicates a variable inside of a {section} named foo.
-If you want to access an array element with index foo, you must use quotes
-such as {$bar['foo']}, or use the dot syntax {$bar.foo}.
-
-while block tag is now implemented:
-{while $foo}...{/while}
-{while $x lt 10}...{/while}
-
-Direct access to PHP functions:
-Just as you can use PHP functions as modifiers directly, you can now access
-PHP functions directly, provided they are permitted by security settings:
-{time()}
-
-There is a new {function}...{/function} block tag to implement a template function.
-This enables reuse of code sequences like a plugin function. It can call itself recursively.
-Template function must be called with the new {call name=foo...} tag.
-
-Example:
-
-Template file:
-{function name=menu level=0}
-  <ul class="level{$level}">
-  {foreach $data as $entry}
-    {if is_array($entry)}
-      <li>{$entry@key}</li>
-       {call name=menu data=$entry level=$level+1}
-    {else}
-      <li>{$entry}</li>
-    {/if}
-  {/foreach}
-  </ul>
-{/function}
-
-{$menu = ['item1','item2','item3' => ['item3-1','item3-2','item3-3' =>
-  ['item3-3-1','item3-3-2']],'item4']}
-
-{call name=menu data=$menu}
-
-
-Generated output:
-    * item1
-    * item2
-    * item3
-          o item3-1
-          o item3-2
-          o item3-3
-                + item3-3-1
-                + item3-3-2
-    * item4
-
-The function tag itself must have the "name" attribute. This name is the tag
-name when calling the function. The function tag may have any number of
-additional attributes. These will be default settings for local variables.
-
-New {nocache} block function:
-{nocache}...{/nocache} will declare a section of the template to be non-cached
-when template caching is enabled.
-
-New nocache attribute:
-You can declare variable/function output as non-cached with the nocache attribute.
-Examples:
-
-{$foo nocache=true}
-{$foo nocache} /* same */
-
-{foo bar="baz" nocache=true}
-{foo bar="baz" nocache} /* same */
-
-{time() nocache=true}
-{time() nocache} /* same */
-
-Or you can also assign the variable in your script as nocache:
-$smarty->assign('foo',$something,true); // third param is nocache setting
-{$foo} /* non-cached */
-
-$smarty.current_dir returns the directory name of the current template.
-
-You can use strings directly as templates with the "string" resource type.
-Examples:
-$smarty->display('string:This is my template, {$foo}!'); // php
-{include file="string:This is my template, {$foo}!"} // template
-
-
-
-VARIABLE SCOPE / VARIABLE STORAGE
-=================================
-
-In Smarty 2, all assigned variables were stored within the Smarty object.
-Therefore, all variables assigned in PHP were accessible by all subsequent
-fetch and display template calls.
-
-In Smarty 3, we have the choice to assign variables to the main Smarty object,
-to user-created data objects, and to user-created template objects.
-These objects can be chained. The object at the end of a chain can access all
-variables belonging to that template and all variables within the parent objects.
-The Smarty object can only be the root of a chain, but a chain can be isolated
-from the Smarty object.
-
-All known Smarty assignment interfaces will work on the data and template objects.
-
-Besides the above mentioned objects, there is also a special storage area for
-global variables.
-
-A Smarty data object can be created as follows:
-$data = $smarty->createData();    // create root data object
-$data->assign('foo','bar');       // assign variables as usual
-$data->config_load('my.conf');									 // load config file
-
-$data= $smarty->createData($smarty);  // create data object having a parent link to
-the Smarty object
-
-$data2= $smarty->createData($data);   // create data object having a parent link to
-the $data data object
-
-A template object can be created by using the createTemplate method. It has the
-same parameter assignments as the fetch() or display() method.
-Function definition:
-function createTemplate($template, $cache_id = null, $compile_id = null, $parent = null)
-
-The first parameter can be a template name, a smarty object or a data object.
-
-Examples:
-$tpl = $smarty->createTemplate('mytpl.tpl'); // create template object not linked to any parent
-$tpl->assign('foo','bar');                   // directly assign variables
-$tpl->config_load('my.conf');									 // load config file
-
-$tpl = $smarty->createTemplate('mytpl.tpl',$smarty);  // create template having a parent link to the Smarty object
-$tpl = $smarty->createTemplate('mytpl.tpl',$data);    // create template having a parent link to the $data object
-
-The standard fetch() and display() methods will implicitly create a template object.
-If the $parent parameter is not specified in these method calls, the template object
-is will link back to the Smarty object as it's parent.
-
-If a template is called by an {include...} tag from another template, the
-subtemplate links back to the calling template as it's parent.
-
-All variables assigned locally or from a parent template are accessible. If the
-template creates or modifies a variable by using the {assign var=foo...} or
-{$foo=...} tags, these new values are only known locally (local scope). When the
-template exits, none of the new variables or modifications can be seen in the
-parent template(s). This is same behavior as in Smarty 2.
-
-With Smarty 3, we can assign variables with a scope attribute which allows the
-availablility of these new variables or modifications globally (ie in the parent
-templates.)
-
-Possible scopes are local, parent, root and global.
-Examples:
-{assign var=foo value='bar'}       // no scope is specified, the default 'local'
-{$foo='bar'}                       // same, local scope
-{assign var=foo value='bar' scope='local'} // same, local scope
-
-{assign var=foo value='bar' scope='parent'} // Values will be available to the parent object
-{$foo='bar' scope='parent'}                 // (normally the calling template)
-
-{assign var=foo value='bar' scope='root'}   // Values will be exported up to the root object, so they can
-{$foo='bar' scope='root'}                   // be seen from all templates using the same root.
-
-{assign var=foo value='bar' scope='global'} // Values will be exported to global variable storage,
-{$foo='bar' scope='global'}                 // they are available to any and all templates.
-
-
-The scope attribute can also be attached to the {include...} tag. In this case,
-the specified scope will be the default scope for all assignments within the
-included template.
-
-
-PLUGINS
-=======
-
-Smarty 3 plugins follow the same coding rules as in Smarty 2.
-The main difference is that the template object is now passed in place of the smarty object.
-The smarty object can be still be accessed through $template->smarty.
-
-smarty_plugintype_name (array $params, Smarty_Internal_Template $template)
-
-The Smarty 2 plugins are still compatible as long as they do not make use of specific Smarty 2 internals.
-
-
-TEMPLATE INHERITANCE:
-=====================
-
-With template inheritance you can define blocks, which are areas that can be
-overridden by child templates, so your templates could look like this:
-
-parent.tpl:
-<html>
-  <head>
-    <title>{block name='title'}My site name{/block}</title>
-  </head>
-  <body>
-    <h1>{block name='page-title'}Default page title{/block}</h1>
-    <div id="content">
-      {block name='content'}
-        Default content
-      {/block}
-    </div>
-  </body>
-</html>
-
-child.tpl:
-{extends file='parent.tpl'}
-{block name='title'}
-Child title
-{/block}
-
-grandchild.tpl:
-{extends file='child.tpl'}
-{block name='title'}Home - {$smarty.block.parent}{/block}
-{block name='page-title'}My home{/block}
-{block name='content'}
-  {foreach $images as $img}
-    <img src="{$img.url}" alt="{$img.description}" />
-  {/foreach}
-{/block}
-
-We redefined all the blocks here, however in the title block we used {$smarty.block.parent},
-which tells Smarty to insert the default content from the parent template in its place.
-The content block was overridden to display the image files, and page-title has also be
-overridden to display a completely different title.
-
-If we render grandchild.tpl we will get this:
-<html>
-  <head>
-    <title>Home - Child title</title>
-  </head>
-  <body>
-    <h1>My home</h1>
-    <div id="content">
-      <img src="/example.jpg" alt="image" />
-      <img src="/example2.jpg" alt="image" />
-      <img src="/example3.jpg" alt="image" />
-    </div>
-  </body>
-</html>
-
-NOTE: In the child templates everything outside the {extends} or {block} tag sections
-is ignored.
-
-The inheritance tree can be as big as you want (meaning you can extend a file that
-extends another one that extends another one and so on..), but be aware that all files
-have to be checked for modifications at runtime so the more inheritance the more overhead you add.
-
-Instead of defining the parent/child relationships with the {extends} tag in the child template you
-can use the resource as follow:
-
-$smarty->display('extends:parent.tpl|child.tpl|grandchild.tpl');
-
-Child {block} tags may optionally have a append or prepend attribute. In this case the parent block content
-is appended or prepended to the child block content.
-
-{block name='title' append} My title {/block}

-STATIC CLASS ACCESS AND NAMESPACE SUPPORT
-=========================================
-
-You can register a class with optional namespace for the use in the template like:
-
-$smarty->register->templateClass('foo','name\name2\myclass');
-
-In the template you can use it like this:
-{foo::method()}  etc.

-= Known incompatibilities with Smarty 2 =
-
-== Syntax ==
-
-Smarty 3 API has a new syntax. Much of the Smarty 2 syntax is supported
-by a wrapper but deprecated. See the README that comes with Smarty 3 for more
-information.
-
-The {$array|@mod} syntax has always been a bit confusing, where an "@" is required
-to apply a modifier to an array instead of the individual elements. Normally you
-always want the modifier to apply to the variable regardless of its type. In Smarty 3,
-{$array|mod} and {$array|@mod} behave identical. It is safe to drop the "@" and the
-modifier will still apply to the array. If you really want the modifier to apply to
-each array element, you must loop the array in-template, or use a custom modifier that
-supports array iteration. Most smarty functions already escape values where necessary
-such as {html_options}
-
-== PHP Version ==
-Smarty 3 is PHP 5 only. It will not work with PHP 4.
-
-== {php} Tag ==
-The {php} tag is disabled by default. The use of {php} tags is
-deprecated. It can be enabled with $smarty->allow_php_tag=true.
-
-But if you scatter PHP code which belongs together into several
-{php} tags it may not work any longer.
-
-== Delimiters and whitespace ==
-Delimiters surrounded by whitespace are no longer treated as Smarty tags.
-Therefore, { foo } will not compile as a tag, you must use {foo}. This change
-Makes Javascript/CSS easier to work with, eliminating the need for {literal}.
-This can be disabled by setting $smarty->auto_literal = false;
-
-== Unquoted Strings ==
-Smarty 2 was a bit more forgiving (and ambiguous) when it comes to unquoted strings
-in parameters. Smarty3 is more restrictive. You can still pass strings without quotes
-so long as they contain no special characters. (anything outside of A-Za-z0-9_)
-
-For example filename strings must be quoted
-<source lang="smarty">
-{include file='path/foo.tpl'}
-</source>
-
-== Extending the Smarty class ==
-Smarty 3 makes use of the __construct method for initialization. If you are extending
-the Smarty class, its constructor is not called implicitly if the your child class defines
-its own constructor. In order to run Smarty's constructor, a call to parent::__construct()
-within your child constructor is required.
-
-<source lang="php">
-class MySmarty extends Smarty {
-   function __construct() {
-       parent::__construct();
-
-       // your initialization code goes here
-
-   }
-}
-</source>
-
-== Autoloader ==
-Smarty 3 does register its own autoloader with spl_autoload_register. If your code has
-an existing __autoload function then this function must be explicitly registered on
-the __autoload stack. See http://us3.php.net/manual/en/function.spl-autoload-register.php
-for further details.
-
-== Plugin Filenames ==
-Smarty 3 optionally supports the PHP spl_autoloader. The autoloader requires filenames
-to be lower case. Because of this, Smarty plugin file names must also be lowercase.
-In Smarty 2, mixed case file names did work.
-
-== Scope of Special Smarty Variables ==
-In Smarty 2 the special Smarty variables $smarty.section... and $smarty.foreach...
-had global scope. If you had loops with the same name in subtemplates you could accidentally
-overwrite values of parent template.
-
-In Smarty 3 these special Smarty variable have only local scope in the template which
-is defining the loop. If you need their value in a subtemplate you have to pass them
-as parameter.
-<source lang="smarty">
-{include file='path/foo.tpl' index=$smarty.section.foo.index}
-</source>
-
-== SMARTY_RESOURCE_CHAR_SET ==
-Smarty 3 sets the constant SMARTY_RESOURCE_CHAR_SET to utf-8 as default template charset.
-This is now used also on modifiers like escape as default charset. If your templates use
-other charsets make sure that you define the constant accordingly. Otherwise you may not
-get any output.
-
-== newline at {if} tags ==
-A \n was added to the compiled code of the {if},{else},{elseif},{/if} tags to get output of newlines as expected by the template source.
-If one of the {if} tags is at the line end you will now get a newline in the HTML output.
-
-== trigger_error() ==
-The API function trigger_error() has been removed because it did just map to PHP trigger_error.
-However it's still included in the Smarty2 API wrapper.
-
-== Smarty constants ==
-The constants
-SMARTY_PHP_PASSTHRU
-SMARTY_PHP_QUOTE
-SMARTY_PHP_REMOVE
-SMARTY_PHP_ALLOW
-have been replaced with class constants
-Smarty::PHP_PASSTHRU
-Smarty::PHP_QUOTE
-Smarty::PHP_REMOVE
-Smarty::PHP_ALLOW
-
@@ -1,24 +0,0 @@
-== Smarty2 backward compatibility ==
-All Smarty2 specific API functions and deprecated functionality has been moved
-to the SmartyBC class.
-
-== {php} Tag ==
-The {php} tag is no longer available in the standard Smarty calls.
-The use of {php} tags is deprecated and only available in the SmartyBC class.
-
-== {include_php} Tag ==
-The {include_php} tag is no longer available in the standard Smarty calls.
-The use of {include_php} tags is deprecated and only available in the SmartyBC class.
-
-== php template resource ==
-The support of the php template resource is removed.
-
-== $cache_dir, $compile_dir, $config_dir, $template_dir access ==
-The mentioned properties can't be accessed directly any longer. You must use
-corresponding getter/setters like addConfigDir(), setConfigDir(), getConfigDir()

-Smarty 3.1 Notes
-================
-
-Smarty 3.1 is a departure from 2.0 compatibility. Most notably, all
-backward compatibility has been moved to a separate class file named
-SmartyBC.class.php. If you require compatibility with 2.0, you will
-need to use this class.
-
-Some differences from 3.0 are also present. 3.1 begins the journey of
-requiring setters/getters for property access. So far this is only
-implemented on the five directory properties: template_dir,
-plugins_dir, configs_dir, compile_dir and cache_dir. These properties
-are now protected, it is required to use the setters/getters instead.
-That said, direct property access will still work, however slightly
-slower since they will now fall through __set() and __get() and in
-turn passed through the setter/getter methods. 3.2 will exhibit a full
-list of setter/getter methods for all (currently) public properties,
-so code-completion in your IDE will work as expected.
-
-There is absolutely no PHP allowed in templates any more. All
-deprecated features of Smarty 2.0 are gone. Again, use the SmartyBC
-class if you need any backward compatibility.
-
-Internal Changes
-
-  Full UTF-8 Compatibility
-
-The plugins shipped with Smarty 3.1 have been rewritten to fully
-support UTF-8 strings if Multibyte String is available. Without
-MBString UTF-8 cannot be handled properly. For those rare cases where
-templates themselves have to juggle encodings, the new modifiers
-to_charset and from_charset may come in handy.
-
-  Plugin API and Performance
-
-All Plugins (modifiers, functions, blocks, resources,
-default_template_handlers, etc) are now receiving the
-Smarty_Internal_Template instance, where they were supplied with the
-Smarty instance in Smarty 3.0. *. As The Smarty_Internal_Template
-mimics the behavior of Smarty, this API simplification should not
-require any changes to custom plugins.
-
-The plugins shipped with Smarty 3.1 have been rewritten for better
-performance. Most notably {html_select_date} and {html_select_time}
-have been improved vastly. Performance aside, plugins have also been
-reviewed and generalized in their API. {html_select_date} and
-{html_select_time} now share almost all available options.
-
-The escape modifier now knows the $double_encode option, which will
-prevent entities from being encoded again.
-
-The capitalize modifier now know the $lc_rest option, which makes sure
-all letters following a capital letter are lower-cased.
-
-The count_sentences modifier now accepts (.?!) as
-legitimate endings of a sentence - previously only (.) was
-accepted
-
-The new unescape modifier is there to reverse the effects of the
-escape modifier. This applies to the escape formats html, htmlall and
-entity.
-
-  default_template_handler_func
-
-The invocation of $smarty->$default_template_handler_func had to be
-altered. Instead of a Smarty_Internal_Template, the fifth argument is
-now provided with the Smarty instance. New footprint:
-
-
-/**
- * Default Template Handler
- *
- * called when Smarty's file: resource is unable to load a requested file
- *
- * @param string   $type     resource type (e.g. "file", "string", "eval", "resource")
- * @param string   $name     resource name (e.g. "foo/bar.tpl")
- * @param string  &$content  template's content
- * @param integer &$modified template's modification time
- * @param Smarty   $smarty   Smarty instance
- * @return string|boolean   path to file or boolean true if $content and $modified
- *                          have been filled, boolean false if no default template
- *                          could be loaded
- */
-function default_template_handler_func($type, $name, &$content, &$modified, Smarty $smarty) {
-    if (false) {
-        // return corrected filepath
-        return "/tmp/some/foobar.tpl";
-    } elseif (false) {
-        // return a template directly
-        $content = "the template source";
-        $modified = time();
-        return true;
-    } else {
-        // tell smarty that we failed
-        return false;
-    }
-}
-
-  Stuff done to the compiler
-
-Many performance improvements have happened internally. One notable
-improvement is that all compiled templates are now handled as PHP
-functions. This speeds up repeated templates tremendously, as each one
-calls an (in-memory) PHP function instead of performing another file
-include/scan.
-
-New Features
-
-  Template syntax
-
- {block}..{/block}
-
-The {block} tag has a new hide option flag. It does suppress the block
-content if no corresponding child block exists.
-EXAMPLE:
-parent.tpl
-{block name=body hide} child content "{$smarty.block.child}" was
-inserted {block}
-In the above example the whole block will be suppressed if no child
-block "body" is existing.
-
- {setfilter}..{/setfilter}
-
-The new {setfilter} block tag allows the definition of filters which
-run on variable output.
-SYNTAX:
-{setfilter filter1|filter2|filter3....}
-Smarty3 will lookup up matching filters in the following search order:
-1. variable filter plugin in plugins_dir.
-2. a valid modifier. A modifier specification will also accept
-additional parameter like filter2:'foo'
-3. a PHP function
-{/setfilter} will turn previous filter setting off again.
-{setfilter} tags can be nested.
-EXAMPLE:
-{setfilter filter1}
-  {$foo}
-  {setfilter filter2}
-    {$bar}
-  {/setfilter}
-  {$buh}
-{/setfilter}
-{$blar}
-In the above example filter1 will run on the output of $foo, filter2
-on $bar, filter1 again on $buh and no filter on $blar.
-NOTES:
- {$foo nofilter} will suppress the filters
- These filters will run in addition to filters defined by
-registerFilter('variable',...), autoLoadFilter('variable',...) and
-defined default modifier.
- {setfilter} will effect only the current template, not included
-subtemplates.
-
-  Resource API
-
-Smarty 3.1 features a new approach to resource management. The
-Smarty_Resource API allows simple, yet powerful integration of custom
-resources for templates and configuration files. It offers simple
-functions for loading data from a custom resource (e.g. database) as
-well as define new template types adhering to the special
-non-compiling (e,g, plain php) and non-compile-caching (e.g. eval:
-resource type) resources.
-
-See demo/plugins/resource.mysql.php for an example custom database
-resource.
-
-Note that old-fashioned registration of callbacks for resource
-management has been deprecated but is still possible with SmartyBC.
-
-  CacheResource API
-
-In line with the Resource API, the CacheResource API offers a more
-comfortable handling of output-cache data. With the
-Smarty_CacheResource_Custom accessing databases is made simple. With
-the introduction of Smarty_CacheResource_KeyValueStore the
-implementation of resources like memcache or APC became a no-brainer;
-simple hash-based storage systems are now supporting hierarchical
-output-caches.
-
-See demo/plugins/cacheresource.mysql.php for an example custom
-database CacheResource.
-See demo/plugins/cacheresource.memcache.php for an example custom
-memcache CacheResource using the KeyValueStore helper.
-
-Note that old-fashioned registration of $cache_handler is not possible
-anymore. As the functionality had not been ported to Smarty 3.0.x
-properly, it has been dropped from 3.1 completely.
-
-Locking facilities have been implemented to avoid concurrent cache
-generation. Enable cache locking by setting
-$smarty->cache_locking = true;
-
-  Relative Paths in Templates (File-Resource)
-
-As of Smarty 3.1 {include file="../foo.tpl"} and {include
-file="./foo.tpl"} will resolve relative to the template they're in.
-Relative paths are available with {include file="..."} and
-{extends file="..."}. As $smarty->fetch('../foo.tpl') and
-$smarty->fetch('./foo.tpl') cannot be relative to a template, an
-exception is thrown.
-
-  Addressing a specific $template_dir
-
-Smarty 3.1 introduces the $template_dir index notation.
-$smarty->fetch('[foo]bar.tpl') and {include file="[foo]bar.tpl"}
-require the template bar.tpl to be loaded from $template_dir['foo'];
-Smarty::setTemplateDir() and Smarty::addTemplateDir() offer ways to
-define indexes along with the actual directories.
-
-  Mixing Resources in extends-Resource
-
-Taking the php extends: template resource one step further, it is now
-possible to mix resources within an extends: call like
-$smarty->fetch("extends:file:foo.tpl|db:bar.tpl");
-
-To make eval: and string: resources available to the inheritance
-chain, eval:base64:TPL_STRING and eval:urlencode:TPL_STRING have been
-introduced. Supplying the base64 or urlencode flags will trigger
-decoding the TPL_STRING in with either base64_decode() or urldecode().
-
-  extends-Resource in template inheritance
-
-Template based inheritance may now inherit from php's extends:
-resource like {extends file="extends:foo.tpl|db:bar.tpl"}.
-
-  New Smarty property escape_html
-
-$smarty->escape_html = true will autoescape all template variable
-output by calling htmlspecialchars({$output}, ENT_QUOTES,
-SMARTY_RESOURCE_CHAR_SET).
-NOTE:
-This is a compile time option. If you change the setting you must make
-sure that the templates get recompiled.
-
-  New option at Smarty property compile_check
-
-The automatic recompilation of modified templates can now be
-controlled by the following settings:
-$smarty->compile_check = COMPILECHECK_OFF (false) - template files
-will not be checked
-$smarty->compile_check = COMPILECHECK_ON (true) - template files will
-always be checked
-$smarty->compile_check = COMPILECHECK_CACHEMISS - template files will
-be checked if caching is enabled and there is no existing cache file
-or it has expired
-
-  Automatic recompilation on Smarty version change
-
-Templates will now be automatically recompiled on Smarty version
-changes to avoide incompatibillities in the compiled code. Compiled
-template checked against the current setting of the SMARTY_VERSION
-constant.
-
-  default_config_handler_func()
-
-Analogous to the default_template_handler_func()
-default_config_handler_func() has been introduced.
-
-  default_plugin_handler_func()
-
-An optional default_plugin_handler_func() can be defined which gets called
-by the compiler on tags which can't be resolved internally or by plugins.
-The default_plugin_handler() can map tags to plugins on the fly.
-
-New getters/setters
-
-The following setters/getters will be part of the official
-documentation, and will be strongly recommended. Direct property
-access will still work for the foreseeable future... it will be
-transparently routed through the setters/getters, and consequently a
-bit slower.
-
-array|string getTemplateDir( [string $index] )
-replaces $smarty->template_dir; and $smarty->template_dir[$index];
-Smarty setTemplateDir( array|string $path )
-replaces $smarty->template_dir = "foo"; and $smarty->template_dir =

-                Of particular note is that this value will be 0 if the statement that caused the error was
-                prepended by the @ error-control operator.
-
-            Smarty deliberately uses @filemtime() over file_exists() and filemtime() in some places. Reasons include
-                - @filemtime() is almost twice as fast as using an additional file_exists()
-                - between file_exists() and filemtime() a possible race condition is opened,
-                  which does not exist using the simple @filemtime() approach.

Simon Wisselink	39b69f0142	Feature/php8 support (#629 ) Adds support for PHP8.0, dropping support for PHP7.0 and below. Backwards incompatible changes: - Dropped support for php asp tags in templates (removed from php since php7.0) - Dropped deprecated API calls that where only accessible through SmartyBC - Dropped support for {php} and {include_php} tags and embedded PHP in templates. Embedded PHP will now be passed through as is. - Removed all PHP_VERSION_ID and compare_version checks and conditional code blocks that are now no longer required - Dropped deprecated SMARTY_RESOURCE_CHAR_SET and SMARTY_RESOURCE_DATE_FORMAT constants - Dropped deprecated Smarty::muteExpectedErrors and Smarty::unmuteExpectedErrors API methods - Dropped deprecated $smarty->getVariable() method. Use $smarty->getTemplateVars() instead. - $smarty->registerResource() no longer accepts an array of callback functions See the changelog for more details. Switched CI from Travis to Github CI.	2021-10-13 12:15:17 +02:00

Simon Wisselink	c295786e43	Fixes for php8.0.0beta3 (#608 ) * Set $errcontext argument optional to support PHP 8 - Argument is optional and deprecated in PHP 7.2 * Getting ready for PHP8, handling changed error levels/handlers mostly * php5 compat syntax * Updated UndefinedTemplateVarTest for PHP8 (and disabled a check for PHP<5.6) and re-enabled php:nightly in travis config * Attempt to fix travis runs for (almost) all php versions supported * Fix unit tests for php8, force composer to think we are still php7 to pick a supported phpunit and being less specific about an error msg because PHP8 is in active development and the exact wording is changing. * Fixed a unit test that accidentally passed on phpunit < 7 because of sloppy string comparison. * changelog * run travis in xenial where possible for latest php versions. Fix unit tests from freakingo over inconsistent error messages in php8-beta. * Incorporated AnrDaemons suggestions, making composer figure out the required phpunit version instead of specifying it explicitly and removing a unneeded error supression (@).
