 ## [Unreleased]

+### Fixed
+- The {debug} tag was broken in v5 [#922](https://github.com/smarty-php/smarty/issues/922)
+
+## [5.0.0-rc2] - 2023-11-11
+
+### Fixed
+- Registered output filters wouldn't run [#899](https://github.com/smarty-php/smarty/issues/899)
+- Use of negative numbers in {math} equations [#895](https://github.com/smarty-php/smarty/issues/895)
+- Do not auto-html-escape custom function results [#906](https://github.com/smarty-php/smarty/issues/906)
+- Fix case-sensitive tag names [#907](https://github.com/smarty-php/smarty/issues/907)
+
+### Removed
+- Removed `$smarty->registered_filters` array
+
+## [5.0.0-rc1] - 2023-08-08
+
+### Added
+- Added support for PHP8.2
+- Added a new way to extend Smarty functionality using `Smarty::addExtension()` or `Smarty::setExtensions()`. Please see the docs for more information.
+- Custom tags can accept positional parameters, so you can write a block compiler that support this: `{trans "Jack" "dull boy"}All work and no play makes %s a %s.{/trans}` [#164](https://github.com/smarty-php/smarty/issues/164)
+- Full support for ternary operator: `{$test ? $a : $b}` and `{$var ?: $value_if_falsy}` [#881](https://github.com/smarty-php/smarty/issues/881)
+- Full support for null coalescing operator: `{$var ?? $value_if_null}` [#882](https://github.com/smarty-php/smarty/issues/882)
+
+### Changed
+- All Smarty code is now in the \Smarty namespace. For simple use-cases, you only need to add
+  `use \Smarty\Smarty;` to your script and everything will work. If you extend Smarty or use
+  Smarty plug-ins, please review your code to see if they assume specific class or method names.
+  E.g.: `Smarty_Internal_Template` is now `\Smarty\Template\`, `SmartyException` is now `\Smarty\Exception`.
+- Template variable scope bubbling has been simplified and made more consistent. 
+  The global scope now equals the Smarty scope in order to avoid global state side effects. Please read
+  the documentation for more details.
+- Lexers and Parsers PHP files are reliably generated from sources (.y and .plex) using the make file 
+- Smarty now always runs in multibyte mode, using `symfony/polyfill-mbstring` if required. Please use the
+  multibyte extension for optimal performance.
+- Smarty no longer calls `mb_internal_encoding()` and doesn't check for deprecated `mbstring.func_overload` ini directive [#480](https://github.com/smarty-php/smarty/issues/480)
+- Generated `<script>` tags lo longer have deprecated `type="text/javascript"` or `language="Javascript"` attributes [#815](https://github.com/smarty-php/smarty/issues/815)
+- Smarty will throw a compiler exception instead of silently ignoring a modifier on a function call, like this: `{include|dot:"x-template-id" file="included.dot.tpl"}` [#526](https://github.com/smarty-php/smarty/issues/526) 
+- The documentation was largely rewritten
+
+### Deprecated
+- `$smarty->getPluginsDir()`
+- `$smarty->loadFilter()`
+- `$smarty->setPluginsDir()`
+- `$smarty->assignGlobal()`
+- Using `$smarty->registerFilter()` for registering variable filters will trigger a notice.
+
+### Removed
+- Dropped support for PHP7.1
+- Removed `$smarty->left_delimiter` and `$smarty->right_delimiter`, use `$smarty->getLeftDelimiter()`/`$smarty->setLeftDelimiter()` and `$smarty->getRightDelimiter()`/`$smarty->setRightDelimiter()`
+- Removed support for the `$cache_attrs` parameter for registered plugins
+- Removed support for undocumented `{make_nocache}` tag
+- Removed support for deprecated `{insert}` tag, the 'insert' plugin type and the associated $smarty->trusted_dir variable
+- Removed the undocumented `{block_parent}` and `{parent}` alternatives to `{$smarty.block.parent}`
+- Removed the undocumented `{block_child}` and `{child}` alternatives to `{$smarty.block.child}`
+- Removed support for loading config files into a non-local scope using `{config_load}` from a template 
+- Removed `$smarty->autoload_filters` in favor of `$smarty->registerFilter()`
+- Removed `$smarty->trusted_dir` and `$smarty->allow_php_templates` since support for executing php scripts from templates has been dropped  
+- Removed `$smarty->php_functions` and `$smarty->php_modifiers`. 
+- You can no longer use native PHP-functions or userland functions in your templates without registering them. If you need a function in your templates,
+  register it first.
+- Removed support for `$smarty->getTags()`
+- Removed the abandoned `$smarty->direct_access_security` setting
+- Dropped support for `$smarty->plugins_dir` and `$smarty->use_include_path`. If you must, use `$smarty->addPluginsDir()` instead,
+  but it's better to use Smarty::addExtension() to add an extension or Smarty::registerPlugin to
+  quickly register a plugin using a callback function.
+- Removed constants such as SMARTY_DIR to prevent global side effects.
+- Removed direct access to `$smarty->template_dir`. Use `$smarty->setTemplateDir()`.
+- Removed direct access to `$smarty->cache_dir`. Use `$smarty->setCacheDir()`.
+- Removed direct access to `$smarty->compile_dir`. Use `$smarty->setCompileDir()`.
+- Removed `$smarty->loadPlugin()`, use `$smarty->registerPlugin()` instead.
+- Removed `$smarty->appendByRef()` and `$smarty->assignByRef()`.
+- Removed `$smarty->_current_file`
+- Removed `$smarty->allow_ambiguous_resources` (ambiguous resources handlers should still work)
+
+### Fixed
+- `|strip_tags` does not work if the input is 0 [#890](https://github.com/smarty-php/smarty/issues/890)
+
+## [4.3.2] - 2023-07-19
+
+### Fixed
+- `$smarty->muteUndefinedOrNullWarnings()` now also mutes PHP8 warnings for undefined properties
+
+## [4.3.1] - 2023-03-28
+
+### Security
+- Fixed Cross site scripting vulnerability in Javascript escaping. This addresses CVE-2023-28447.
+
+### Fixed
+- `$smarty->muteUndefinedOrNullWarnings()` now also mutes PHP7 notices for undefined array indexes [#736](https://github.com/smarty-php/smarty/issues/736)
+- `$smarty->muteUndefinedOrNullWarnings()` now treats undefined vars and array access of a null or false variables 
+  equivalent across all supported PHP versions
+- `$smarty->muteUndefinedOrNullWarnings()` now allows dereferencing of non-objects across all supported PHP versions [#831](https://github.com/smarty-php/smarty/issues/831)
+- PHP 8.1 deprecation warnings on null strings in modifiers [#834](https://github.com/smarty-php/smarty/pull/834)

 ### Changed
 - Include docs and demo in the releases [#799](https://github.com/smarty-php/smarty/issues/799)

+
+## I Have a Question
+
+> If you want to ask a question, we assume that you have read the available [Documentation](https://smarty-php.github.io/smarty).
+
+Before you ask a question, it is best to search for existing [Issues](https://github.com/smarty-php/smarty/issues) that might help you. 
+In case you have found a suitable issue and still need clarification, you can write your question in this issue. 
+It is also advisable to search the internet for answers first.
+
+If you then still feel the need to ask a question and need clarification, we recommend the following:
+
+- [Open an Issue](https://github.com/smarty-php/smarty/issues/new).
+- Provide as much context as you can about what you're running into.
+- Provide Smarty and PHP versions
+
+We will then take care of the issue as soon as possible.

+
+### Reporting Bugs
+
+#### Before Submitting a Bug Report
+
+A good bug report shouldn't leave others needing to chase you up for more information. Therefore, we ask you to 
+investigate carefully, collect information and describe the issue in detail in your report. Please complete the 
+following steps in advance to help us fix any potential bug as fast as possible.
+
+- Make sure that you are using the latest version.
+- Determine if your bug is really a bug and not an error on your side. (Make sure that you have read the [documentation](https://smarty-php.github.io/smarty). If you are looking for support, you might want to check [this section](#i-have-a-question)).
+- To see if other users have experienced (and potentially already solved) the same issue you are having, check if there is not already a bug report existing for your bug or error in the [bug tracker](https://github.com/smarty-php/smarty/issues?q=label%3Abug).
+- Also make sure to search the internet (including Stack Overflow) to see if users outside of the GitHub community have discussed the issue.
+- Collect information about the bug:
+  - For an Exception: please provide the Stack trace
+  - OS (Windows, Linux, macOS)
+  - PHP version
+  - Smarty version
+  - A minimal snippet of (your) code that triggers the bug
+  - Expected output versus actual output
+  - Can you reliably reproduce the issue? And can you also reproduce it with older versions?
+
+#### How Do I Submit a Good Bug Report?
+
+> You must never report security related issues, vulnerabilities or bugs including sensitive information to the issue tracker, or elsewhere in public. 
+> For sensitive bugs, please see [SECURITY.md](SECURITY.md).
+
+We use GitHub issues to track bugs and errors. If you run into an issue with the project:
+
+- Open an [Issue](https://github.com/smarty-php/smarty/issues/new). (Since we can't be sure at this point whether it is a bug or not, we ask you not to talk about a bug yet and not to label the issue.)
+- Explain the behavior you would expect and the actual behavior.
+- Please provide as much context as possible and describe the *reproduction steps* that someone else can follow to recreate the issue on their own. This usually includes your code. For good bug reports you should isolate the problem and create a reduced test case.
+- Provide the information you collected in the previous section.
+
+Once it's filed:
+
+- The project team will label the issue accordingly.
+- A team member will try to reproduce the issue with your provided steps. If there are no reproduction steps or no obvious way to reproduce the issue, the team will ask you for those steps and mark the issue as `needs-repro`. Bugs with the `needs-repro` tag will not be addressed until they are reproduced.
+- If the team is able to reproduce the issue, it will be marked `needs-fix`, as well as possibly other tags (such as `critical`), and the issue will be left to be implemented by someone.
+
+
+
+### Suggesting Enhancements
+
+This section guides you through submitting an enhancement suggestion for CONTRIBUTING.md, **including completely new features and minor improvements to existing functionality**. Following these guidelines will help maintainers and the community to understand your suggestion and find related suggestions.
+
+
+#### Before Submitting an Enhancement
+
+- Make sure that you are using the latest version.
+- Read the [documentation](https://smarty-php.github.io/smarty) carefully and find out if the functionality is already covered, maybe by an individual configuration.
+- Perform a [search](https://github.com/smarty-php/smarty/issues) to see if the enhancement has already been suggested. If it has, add a comment to the existing issue instead of opening a new one.
+- Find out whether your idea fits with the scope and aims of the project. It's up to you to make a strong case to convince the project's developers of the merits of this feature. Keep in mind that we want features that will be useful to the majority of our users and not just a small subset. If you're just targeting a minority of users, consider writing an add-on/plugin library.
+
+
+#### How Do I Submit a Good Enhancement Suggestion?
+
+Enhancement suggestions are tracked as [GitHub issues](https://github.com/smarty-php/smarty/issues).
+
+- Use a **clear and descriptive title** for the issue to identify the suggestion.
+- Provide a **step-by-step description of the suggested enhancement** in as many details as possible.
+- **Describe the current behavior** and **explain which behavior you expected to see instead** and why. At this point you can also tell which alternatives do not work for you.
+- You may want to **include screenshots and animated GIFs** which help you demonstrate the steps or point out the part which the suggestion is related to. You can use [this tool](https://www.cockos.com/licecap/) to record GIFs on macOS and Windows, and [this tool](https://github.com/colinkeenan/silentcast) or [this tool](https://github.com/GNOME/byzanz) on Linux.
+- **Explain why this enhancement would be useful** to most CONTRIBUTING.md users. You may also want to point out the other projects that solved it better and which could serve as inspiration.
+
+
+### Improving The Documentation
+
+The [docs](docs/index.md) are written in markdown, configured in [mkdocs.yml](mkdocs.yml) and published 
+to [GitHub pages](https://smarty-php.github.io/smarty) using [mkdocs](https://www.mkdocs.org/) and [mike](https://github.com/jimporter/mike).
+
+To preview the docs while you are writing, run:
+```bash
+mkdocs serve
+```
+This should launch a local web server and give you a link to open in your browser.
+
+When you are finished, commit your changes and provide a [Pull Request](https://docs.github.com/en/pull-requests/collaborating-with-pull-requests/proposing-changes-to-your-work-with-pull-requests/creating-a-pull-request).
+
+#### Publishing the docs
+If you are a maintainer, you can publish the document using [mike](https://github.com/jimporter/mike). Make sure you provide the correct version.
+
+```bash
+mike deploy 5.x
+```

+# Basics
+
+## Installation
+For installation instructies, please see the [getting started section](../getting-started.md).
+
+## Rendering a template
+Here's how you create an instance of Smarty in your PHP scripts:
+```php
+<?php
+
+require 'vendor/autoload.php';
+use Smarty\Smarty;
+$smarty = new Smarty();
+```
+
+You now have a Smarty object that you can use to render templates.
+
+```php
+<?php
+
+require 'vendor/autoload.php';
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->display('string:The current smarty version is: {$smarty.version}.');
+// or 
+echo $smarty->fetch('string:The current smarty version is: {$smarty.version}.');
+```
+
+## Using file-based templates
+You probably want to manage your templates as files. Create a subdirectory called 'templates' and
+then configure Smarty to use that:
+
+```php
+<?php
+
+require 'vendor/autoload.php';
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->setTemplateDir(__DIR__ . '/templates');
+```
+
+Say you have a template file called 'version.tpl', stored in the 'templates' directory like this:
+```smarty
+<h1>Hi</h1>
+The current smarty version is: {$smarty.version|escape}.
+```
+
+You can now render this, using:
+```php
+<?php
+
+require 'vendor/autoload.php';
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->setTemplateDir(__DIR__ . '/templates');
+$smarty->display('version.tpl');
+```
+
+## Assigning variables
+
+Templates start to become really useful once you add variables to the mix.
+
+Create a template called 'footer.tpl' in the 'templates' directory like this:
+```smarty
+<small>Copyright {$companyName|escape}</small>
+```
+
+Now assign a value to the 'companyName' variable and render your template like this:
+
+```php
+<?php
+
+require 'vendor/autoload.php';
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->setTemplateDir(__DIR__ . '/templates');
+$smarty->assign('companyName', 'AC & ME Corp.');
+$smarty->display('footer.tpl');
+```
+
+Run this, and you will see:
+
+```html
+<small>Copyright AC &amp; ME Corp.</small>
+```
+
+Note how the [escape modifier](../designers/language-modifiers/language-modifier-escape.md) 
+translated the `&` character into the proper HTML syntax `&amp;`.

+# Caching
+
+Caching is used to speed up the rendering of a template by saving and re-using the output. 
+
+If a cached version of the call is available, that is displayed instead of
+regenerating the output. Caching can speed things up tremendously,
+especially templates with longer computation times. 
+
+Since templates can include or extend other templates, one
+cache file could conceivably be made up of several template files,
+config files, etc.
+
+> ** Note **
+> 
+> Since templates are dynamic, it is important to be careful what you are
+> caching and for how long. For instance, if you are displaying the front
+> page of your website that does not change its content very often, it
+> might work well to cache this page for an hour or more. On the other
+> hand, if you are displaying a page with a timetable containing new
+> information by the minute, it would not make sense to cache this page.
+
+## Setting Up Caching
+
+The first thing to do is enable caching by calling `Smarty::setCaching()` with either
+`\Smarty\Smarty::CACHING_LIFETIME_CURRENT` or `\Smarty\Smarty::CACHING_LIFETIME_SAVED`.
+Or with `\Smarty\Smarty::CACHING_OFF` to disable caching again.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+// enable caching, using the current lifetime (see below)
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+// enable caching, using the lifetime set when the cache was saved (see below)
+$smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);
+
+// disable caching
+$smarty->setCaching(Smarty::CACHING_OFF);
+
+$smarty->display('index.tpl');
+```
+
+With caching enabled, the function call to `$smarty->display('index.tpl')` will
+render the template as usual, but also saves a copy of its output. On the
+next call to `$smarty->display('index.tpl')`, the cached copy will be used
+instead of rendering the template again.
+
+> **Note**
+>
+> By default, Smarty saved its caches as files in a dir called `cache` relative to the current 
+> directory. The default directory can be changed using `$smarty->setCacheDir('/some/cache/dir');` 
+> The files are named similar
+> to the template name. Although they end in the `.php` extension, they
+> are not intended to be directly executable. Do not edit these files!
+
+## Cache lifetime
+
+Each cached page has a limited lifetime. The default value is 3600
+seconds, or one hour. After that time expires, the cache is regenerated.
+
+You can change the lifetime as follows:
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT); 
+// or $smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);
+
+// set the cache_lifetime to 5 minutes
+$smarty->setCacheLifetime(5 * 60);
+```
+
+Setting caching to a value of `\Smarty\Smarty::CACHING_LIFETIME_CURRENT` tells Smarty to use
+the current lifetime to determine if the cache has expired.
+
+A value of `\Smarty\Smarty::CACHING\_LIFETIME\_SAVED` tells Smarty to use the lifetime value at the time the
+cache was generated. This way you can set the just before rendering a template to have granular control over
+when that particular cache expires.
+
+An example:
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+// retain current cache lifetime for each specific display call
+$smarty->setCaching(Smarty::CACHING_LIFETIME_SAVED);
+
+// set the cache_lifetime for index.tpl to 5 minutes
+$smarty->setCacheLifetime(300);
+$smarty->display('index.tpl');
+
+// set the cache_lifetime for home.tpl to 1 hour
+$smarty->setCacheLifetime(3600);
+$smarty->display('home.tpl');
+
+// NOTE: the following $cache_lifetime setting will not work when $caching
+// is set to Smarty::CACHING_LIFETIME_SAVED.
+// The cache lifetime for home.tpl has already been set
+// to 1 hour, and will no longer respect the value of $cache_lifetime.
+// The home.tpl cache will still expire after 1 hour.
+$smarty->setCacheLifetime(30); // 30 seconds
+$smarty->display('home.tpl');
+```
+
+## Compile check
+
+By default, every template file and config file that is involved with the cache file
+is checked for modification. If any of the files have been modified
+since the cache was generated, the cache is immediately regenerated.
+
+This is a computational overhead, so for optimum performance, disable this on a production environment:
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+$smarty->setCompileCheck(Smarty::COMPILECHECK_OFF);
+
+$smarty->display('index.tpl');
+```
+
+## Checking if a template is cached
+
+Smarty's `isCached() method can be used to test if a
+template has a valid cache or not. If you have a cached template that
+requires something like a database fetch, you can use this to skip that
+process.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+if (!$smarty->isCached('index.tpl')) {
+    // No cache available, do variable assignments here.
+    $smarty->assign('data', do_expensive_database_calls());
+}
+
+$smarty->display('index.tpl');
+```
+
+## Nocache-blocks
+You can keep parts of a page dynamic (disable caching) with the
+[`{nocache}{/nocache}`](../../designers/language-builtin-functions/language-function-nocache.md) block function, 
+or by using the `nocache` parameter for most template functions.
+
+Let's say the whole page can be cached except for a banner that is
+displayed down the side of the page. By using a [`{nocache}{/nocache}`](../../designers/language-builtin-functions/language-function-nocache.md)
+block for the banner, you can
+keep this element dynamic within the cached content.
+
+## Clearing the cache
+You can clear all the cache files with Smarty's `clearAllCache()` method, or individual cache
+files with the `clearCache()` method.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+// clear only cache for index.tpl
+$smarty->clearCache('index.tpl');
+
+// clear out all cache files
+$smarty->clearAllCache();
+
+// clear out all cache files older than one hour
+$smarty->clearAllCache(3600);
+
+// or, clear all expired caches
+$smarty->clearAllCache(Smarty::CLEAR_EXPIRED);
+```

+# Custom cache storage layers
+
+As an alternative to using the default file-based caching mechanism, you
+can specify a custom cache implementation that will be used to read,
+write and clear cached files.
+
+With a custom cache implementation you could replace the slow filesystem by a
+faster storage engine, centralize the cache to be accessible to multiple
+servers.
+
+Smarty requires implementations to extend `\Smarty\Cacheresource\Base`, but encourages you to either extend 
+`\Smarty\Cacheresource\Custom` or `\Smarty\Cacheresource\KeyValueStore`.
+
+- `\Smarty\Cacheresource\Custom` is a simple API directing all read, write,
+clear calls to your implementation. This API allows you to store
+wherever and however you deem fit. 
+- `\Smarty\Cacheresource\KeyValueStore` allows you to turn any 
+KeyValue-Store (like APC or Memcache) into a full-featured
+CacheResource implementation. Everything around deep
+cache-groups like "a|b|c" is being handled for you in a way that
+guarantees clearing the cache-group "a" will clear all nested groups 
+as well - even though KeyValue-Stores don't allow this kind of
+hierarchy by nature.
+
+Custom CacheResources must be registered on
+runtime with `Smarty\Smarty::setCacheResource()`:
+
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->setCacheResource(new My_CacheResource_Mysql());

+# Multiple caches per template
+
+## Introduction
+
+You can have multiple cache files for a single call to
+`display()` or `fetch()`. 
+
+Let's say that
+a call to `$smarty->display('index.tpl')` may have several different output
+contents depending on some condition, and you want separate caches for
+each one. You can do this by passing a `$cache_id` as the second
+parameter to the function call:
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+$my_cache_id = (int) $_GET['article_id'];
+
+$smarty->display('index.tpl', $my_cache_id);
+```
+
+
+Above, we are passing the variable `$my_cache_id` to
+[`display()`](#api.display) as the `$cache_id`. For each unique value of
+`$my_cache_id`, a separate cache will be generated for `index.tpl`. In
+this example, `article_id` was passed in the URL and is used as the
+`$cache_id`.
+
+> **Note**
+>
+> Be very cautious when passing values from a client (web browser) into
+> Smarty or any PHP application. Although the above example of using the
+> article_id from the URL looks handy, it could have bad consequences.
+> The `$cache_id` is used to create a directory on the file system, so
+> if the user decided to write a script that sends random article_id's at a rapid pace,
+> this could possibly cause problems at the server level.
+> Be sure to sanitize any data passed in before using it. In this example, you might want to check if
+> the article_id is a valid ID in the database.
+
+Be sure to pass the same `$cache_id` as the second parameter to
+`isCached()` and `clearCache()`.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+$my_cache_id = (int) $_GET['article_id'];
+
+if (!$smarty->isCached('index.tpl', $my_cache_id)) {
+    // ...
+}
+
+$smarty->display('index.tpl', $my_cache_id);
+```
+
+## Clearing specific caches
+
+You can clear all caches for a particular `$cache_id` by passing NULL as
+the first parameter to `clearCache()`.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+// clear all caches with "sports" as the $cache_id
+$smarty->clearCache(null, 'sports');
+
+$smarty->display('index.tpl', 'sports');
+```
+
+In this manner, you can "group" your caches together by giving them the
+same `$cache_id`.
+
+## Advanced cache grouping
+
+You can do more elaborate grouping by setting up `$cache_id` groups.
+This is accomplished by separating each sub-group with a vertical bar
+`|` in the `$cache_id` value. You can have as many sub-groups as you
+like.
+
+-   You can think of cache groups like a directory hierarchy. For
+    instance, a cache group of `'a|b|c'` could be thought of as the
+    directory structure `'/a/b/c/'`.
+
+-   `clearCache(null, 'a|b|c')` would be like removing the files
+    `'/a/b/c/*'`. `clearCache(null, 'a|b')` would be like removing the
+    files `'/a/b/*'`.
+
+-   If you specify a template name such as
+    `clearCache('foo.tpl', 'a|b|c')` then Smarty will attempt to remove
+    `'/a/b/c/foo.tpl'`.
+
+-   You CANNOT remove a specified template name under multiple cache
+    groups such as `'/a/b/*/foo.tpl'`, the cache grouping works
+    left-to-right ONLY. You will need to group your templates under a
+    single cache group hierarchy to be able to clear them as a group.
+
+Cache grouping should not be confused with your template directory
+hierarchy, the cache grouping has no knowledge of how your templates are
+structured. So for example, if you have a template structure like
+`themes/blue/index.tpl` and you want to be able to clear all the cache
+files for the "blue" theme, you will need to create a cache group
+structure that mimics your template file structure, such as
+`display('themes/blue/index.tpl', 'themes|blue')`, then clear them with
+`clearCache(null, 'themes|blue')`.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+$smarty->setCaching(Smarty::CACHING_LIFETIME_CURRENT);
+
+// clear all caches with 'sports|basketball' as the first two cache_id groups
+$smarty->clearCache(null, 'sports|basketball');
+
+// clear all caches with "sports" as the first cache_id group. This would
+// include "sports|basketball", or "sports|(anything)|(anything)|(anything)|..."
+$smarty->clearCache(null, 'sports');
+
+// clear the foo.tpl cache file with "sports|basketball" as the cache_id
+$smarty->clearCache('foo.tpl', 'sports|basketball');
+
+$smarty->display('index.tpl', 'sports|basketball');

+# Configuring Smarty
+
+## Setting the template path
+By default, Smarty looks for templates to render in `./templates`.
+
+You can change this, or even use multiple paths to use when looking for templates.
+
+If you need to change this, you can use `setTemplateDir()` or `addTemplateDir()`.
+Use `getTemplateDir()` to retrieve the configured paths.
+
+```php
+<?php
+
+ // set a single directory where the config files are stored
+$smarty->setTemplateDir('./config');
+
+// set multiple directories where config files are stored
+$smarty->setTemplateDir(['./config', './config_2', './config_3']);
+
+// add directory where config files are stored to the current list of dirs
+$smarty->addTemplateDir('./config_1');
+
+// add multiple directories to the current list of dirs
+$smarty->addTemplateDir([
+    './config_2',
+    './config_3',
+]);
+
+// chaining of method calls
+$smarty->setTemplateDir('./config')
+       ->addTemplateDir('./config_1')
+       ->addTemplateDir('./config_2');
+
+// get all directories where config files are stored
+$template_dirs = $smarty->getTemplateDir();
+var_dump($template_dirs); // array
+
+// get directory identified by key
+$template_dir = $smarty->getTemplateDir(0);
+var_dump($template_dir); // string
+```
+
+## Setting the path for compiled templates
+Smarty compiles templates to native PHP to be as fast as possible.
+The default path where these PHP-files are stored is `./templates_c`.
+
+If you need to change this, you can use `setCompileDir()`.
+Use `getCompileDir()` to retrieve the configured path.
+
+```php
+<?php
+
+// set another path to store compiled templates
+$smarty->setCompileDir('/data/compiled_templates');
+
+// get directory where compiled templates are stored
+$compileDir = $smarty->getCompileDir();
+```
+
+
+## Setting the config path
+Smarty can [load data from config files](./variables/config-files.md).
+By default, Smarty loads the config files from `./configs`.
+
+You can change this, or even use multiple paths to use when looking for config files.
+
+If you need to change this, you can use `setConfigDir()` or `addConfigDir()`.
+Use `getConfigDir()` to retrieve the configured paths.
+
+```php
+<?php
+
+ // set a single directory where the config files are stored
+$smarty->setConfigDir('./config');
+
+// set multiple directories where config files are stored

+var_dump($config_dirs); // array
+
+// get directory identified by key
+$config_dir = $smarty->getConfigDir(0);
+var_dump($config_dir); // string
+```
+
+## Setting the path for caches
+Even though Smarty runs templates as native PHP for maximum speed, it still needs to 
+execute the PHP code on each call. If your data doesn't change all that often, you
+may be able to speed up your application even more by using output caching.
+
+Output caching can be a tricky subject, so we devoted an entire [section to caching](./caching/basics.md).
+Be sure to read that if you want to use caching.
+
+By default, Smarty stores caches to PHP-files in a subdirectory named `./cache`.
+
+If you need to change this, you can use `setCacheDir()`.
+Use `getCacheDir()` to retrieve the configured path.
+
+```php
+<?php
+
+// set another path to store caches
+$smarty->setCacheDir('/data/caches');
+
+// get directory where cached templates are stored
+$cacheDir = $smarty->getCacheDir();
+```
+
+## Disabling compile check
+By default, Smarty tests to see if the
+current template has changed since the last time
+it was compiled. If it has changed, it recompiles that template. 
+
+Once an application is put into production, this compile-check step 
+is usually no longer needed and the extra checks can significantly hurt performance. 
+Be sure to disable compile checking on production for maximum performance. 
+```php
+<?php
+$smarty->setCompileCheck(\Smarty\Smarty::COMPILECHECK_OFF);
+```
+
+If [`caching`](./caching/basics.md) is enabled and compile-check is
+enabled, then the cache files will get regenerated if an involved
+template file or config file was updated.
+
+## Charset encoding
+
+There are a variety of encodings for textual data, ISO-8859-1 (Latin1)
+and UTF-8 being the most popular. Unless you change `\Smarty\Smarty::$_CHARSET`,
+Smarty recognizes `UTF-8` as the internal charset.
+
+> **Note**
+>
+> `ISO-8859-1` has been PHP\'s default internal charset since the
+> beginning. Unicode has been evolving since 1991. Since then, it has
+> become the one charset to conquer them all, as it is capable of

+> systems (latin, cyrillic, japanese, ...). `UTF-8` is unicode\'s most
+> used encoding, as it allows referencing the thousands of character
+> with the smallest size overhead possible.
+>
+> Since unicode and UTF-8 are very widespread nowadays, their use is
+> strongly encouraged.
+
+> **Note**
+>
+> Smarty\'s internals and core plugins are truly UTF-8 compatible since
+> Smarty 3.1.

+# Custom block tags
+
+Block tags are tags of the form: `{func} .. {/func}`. In other
+words, they enclose a template block and operate on the contents of this
+block. 
+
+Block functions take precedence over normal tags of the same name, that is, you
+cannot have both custom tag `{func}` and block tag `{func}..{/func}`.
+
+-   By default, your function implementation is called twice by Smarty:
+    once for the opening tag, and once for the closing tag. (See
+    `$repeat` below on how to change this.)
+
+-   Only the opening tag of the block has attributes. All attributes are contained in the `$params`
+    variable as an associative array. The opening tag attributes are
+    also accessible to your function when processing the closing tag.
+
+-   The value of the `$content` variable depends on whether your
+    function is called for the opening or closing tag. In case of the
+    opening tag, it will be NULL, and in case of the closing tag it will
+    be the contents of the template block. Note that the template block
+    will have already been processed by Smarty, so all you will receive
+    is the template output, not the template source.
+
+-   The parameter `$repeat` is passed by reference to the function
+    implementation and provides a possibility for it to control how many
+    times the block is displayed. By default `$repeat` is TRUE at the
+    first call of the block function (the opening tag) and FALSE on all
+    subsequent calls to the block function (the block's closing tag).
+    Each time the function implementation returns with `$repeat` being
+    TRUE, the contents between `{func}...{/func}` are evaluated and the
+    function implementation is called again with the new block contents
+    in the parameter `$content`.
+
+Example:
+```php
+<?php
+
+function smarty_block_translate($params, $content, \Smarty\Template $template, &$repeat) {
+    // only output on the closing tag
+    if (!$repeat){
+        if (isset($content)) {
+            $lang = $params['lang'];

+    }

+# Creating an extension
+
+## Default extensions
+
+In order to organize your custom tags and modifiers, you can create an Extension.
+In fact, most of Smarty itself is organized into two extensions:
+
+- the core extension, which provides the basic language tags such as `{if}`, `{for}` and `{assign}`. 
+- the default extension, which provides all default modifiers such as `|escape`,  `|nl2br` and  `|number_format` 
+  and tags such as `{html_image}`, `{mailto}` and `{textformat}` that are enabled by default, but not necessarily universal.
+
+> ** Note **
+> 
+> There is also the 'BCPluginsAdapter' extension, which does not add any new functionality, but
+> wraps calls to deprecated methods such as `Smarty\Smarty::addPluginsDir()` and `Smarty\Smarty::loadFilter()`.
+
+## Writing your own extension
+
+In order to write your own custom extension, you must write a class that implements `Smarty\Extension\ExtensionInterface`.
+However, it is usually easier to extend `Smarty\Extension\Base` which provides empty implementation for each of the methods
+required by `Smarty\Extension\ExtensionInterface`. This allows you to only override the method(s) you need.
+
+Example:
+```php
+<?php
+
+use Smarty\Extension\Base;
+
+class MyExtension extends Base {
+
+    public function getModifierCompiler(string $modifier): ?\Smarty\Compile\Modifier\ModifierCompilerInterface {
+
+		switch ($modifier) {
+			case 'array_escape': return new MyArrayEscapeModifierCompiler();
+			case 'array_unescape': return new MyArrayUnescapeModifierCompiler();
+        }
+
+		return null;
+	}
+}
+
+```
+Another example, that would allow you to use any valid PHP callable as a modifier in your templates:
+
+```php
+<?php
+
+use Smarty\Extension\Base;
+
+class MyCallablePassThroughExtension extends Base {
+
+    public function getModifierCallback(string $modifierName) {
+    
+        if (is_callable($modifierName)) {
+            return $modifierName;
+        }
+    
+		return null;
+	}
+}
+
+```
+
+Writing an extension allows you to add a group of tags, block tags and modifiers to the Smarty language.
+It also allows you to register pre-, post- and output-filters in a structured way. 
+The files in `src/Extension/` in the `smarty/smarty` dir should give you all the information you need to start
+writing your own extension.
+
+## Registering an extension
+
+When you have written your extension, add it to a Smarty instance as follows:
+
+```php
+<?php
+
+use Smarty\Smarty;
+
+$smarty = new Smarty();
+
+$smarty->addExtension(new MyCustomExtension());
+```
+
+This will add `MyCustomExtension` to the end of the extension list, meaning that you cannot override tags or modifiers
+from one of Smarty's default extensions.
+
+Should you wish to insert your extension at the top of the extension list, or create a very limited Smarty version that
+only contains the core extension, you can use `Smarty\Smarty::setExtensions()` to override the list of extensions.
+
+```php
+<?php
+
+use Smarty\Smarty;
+
+$smarty = new Smarty();
+
+$smarty->setExtensions([
+    new Smarty\Extension\CoreExtension(),

+# Extending Smarty
+
+By default, Smarty is already very complete and powerful. However, you can unlock its real potential by 
+extending Smarty.
+
+There are various ways to extend Smarty for it to suit your needs. You can create custom
+[tags](tags.md), [block tags](block-tags.md) and [modifiers](modifiers.md) by registering a method as a plugin.
+
+If this becomes too messy, you can group your custom tags, modifiers, and more into an [Extension](extensions.md). 
+
@@ -0,0 +1,27 @@
+# Custom modifiers
+
+Modifiers are little functions that are applied
+to a variable in the template before it is displayed or used in some
+other context. Smarty comes with a bunch of [modifiers](../../designers/language-modifiers/index.md), but you can 
+easily add your own.
+
+In order to do so, you must write a function that accepts as its first parameter the value on which the
+modifier is to operate. The rest of the parameters are optional, depending on what kind of operation is to be performed.
+
+The modifier has to return the result of its processing.
+
+For example:
+```php

+function smarty_modifier_substr($string, $offset, $length) {

+# Custom tags
+
+You can add your own tags to the Smarty language. 
+
+## Runtime tags
+
+Usually, you'll add a runtime tag. Adding a runtime tag requires you to provide a callback function that accepts
+two parameters:
+
+- `$params`:  all attributes from the template as an associative array.
+- `$template`: a `Smarty\Template` object representing the template where tag was used.
+
+The output (return value) of the function will be substituted in place
+of the tag in the template.
+
+If the function needs to assign some variables to the template or use
+some other Smarty-provided functionality, it can use the supplied
+`$template` object to do so.
+
+```php
+<?php
+
+function smarty_tag_eightball($params, \Smarty\Template $template): string {
+    $answers = [
+        'Yes',

+}

+```smarty
+Question: Will we ever have time travel?
+Answer: {eightball}.
+```
+
+## Compiler tags
+
+Compiler tags are called only during compilation of the template.
+
+They are useful for injecting PHP code or time-sensitive static content
+into the template. If there is both a compiler function and a runtime tag registered under the same name,
+the compiler function has precedence.
+
+The compiler function is passed two parameters: the params array which
+contains precompiled strings for the attribute values and the Smarty
+object. It's supposed to return the code to be injected into the
+compiled template including the surrounding PHP tags.
+
+Example:
+```php
+<?php
+
+function smarty_compiler_tplheader($params, Smarty $smarty) {
+    return "<?php\necho '" . $smarty->_current_file . " compiled at " . date('Y-m-d H:M'). "';\n?>";
+}
+
+$smarty->registerPlugin(Smarty\Smarty::PLUGIN_COMPILER, 'tplheader', 'smarty_compiler_tplheader');
+```
+
+This function can be called from the template as:
+
+```smarty
+{* this function gets executed at compile time only *}
+{tplheader}
+```
+
+The resulting PHP code in the compiled template would be something like
+this:

+# Template Inheritance
+
+Inheritance allows you to define base templates that can
+be extended by child templates. Extending means that the child template
+can override all or some of the named block areas in the base template.
+
+When you render the child template, the result will as if you rendered
+the base template, with only the block(s) that you have overridden in the 
+child templates differing.
+
+-   The inheritance tree can be as deep as you want, meaning you can
+    extend a file that extends another one that extends another one and
+    so on.
+
+-   The child templates can not define any content besides what's
+    inside [`{block}`](../designers/language-builtin-functions/language-function-block.md) tags they override.
+    Anything outside of [`{block}`](../designers/language-builtin-functions/language-function-block.md) tags will
+    be removed.
+
+-   Template inheritance is a compile time process which creates a
+    single compiled template file. Compared to corresponding solutions
+    based on subtemplates included with the
+    [`{include}`](../designers/language-builtin-functions/language-function-include.md) tag it does have much
+    better performance when rendering.
+
+## Basic inheritance
+
+First, create a base template with one or more [blocks](../designers/language-builtin-functions/language-function-block.md). 
+Then, create a child template. The child template 
+must have an [{extends} tag](../designers/language-builtin-functions/language-function-extends.md) on its first line.
+
+The child template can redefine one or more blocks defined in the base template.
+
+See below for a simple example.
+
+layout.tpl (base)
+
+```smarty
+<html>
+    <head>
+      <title>{block name=title}Default Page Title{/block}</title>
+      {block name=head}{/block}

+    <body>
+        {block name=body}{/block}

+```smarty
+{extends file='layout.tpl'}
+{block name=head}
+  <link href="/css/mypage.css" rel="stylesheet" type="text/css"/>
+  <script src="/js/mypage.js"></script>
+{/block}

+
+mypage.tpl (grandchild)

+```smarty
+{extends file='myproject.tpl'}
+{block name=title}My Page Title{/block}
+{block name=head}
+  <link href="/css/mypage.css" rel="stylesheet" type="text/css"/>
+  <script src="/js/mypage.js"></script>
+{/block}
+{block name=body}My HTML Page Body goes here{/block}
+```
+
+
+To render the above, you would use:
+
+```php
+<?php
+$smarty->display('mypage.tpl');
+```
+
+The resulting output is:
+
+```html
+<html>
+    <head>
+      <title>My Page Title</title>
+      <link href="/css/mypage.css" rel="stylesheet" type="text/css"/>

+    </head>
+    <body>
+     My HTML Page Body goes here
+    </body>
+</html>
+```

+> **Note**
+>
+> When [compile-check](./configuring.md#disabling-compile-check) is enabled, all files

+# Rendering templates
+
+## Fetching or rendering templates directly
+As explained in [basics](basics.md), you can use `$smarty->fetch()` or `$smarty->display()`
+to render a template directly.
+
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->display('homepage.tpl');
+
+// or
+
+$output = $smarty->fetch('homepage.tpl');
+```
+
+When you use `display()`, Smarty renders the template to the standard output stream.
+`fetch()` returns the output instead of echoing it.
+
+The example above uses simple filenames to load the template. Smarty also supports
+[loading templates from resources](resources.md).
+
+## Creating a template object
+You can also create a template object which later can be prepared first,
+and rendered later. This can be useful, for example if you plan to re-use several 
+templates.
+
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+// create template object with its private variable scope
+$tpl = $smarty->createTemplate('index.tpl');
+
+// assign a variable (available only to this template)
+$tpl->assign('title', 'My Homepage!');
+
+// display the template
+$tpl->display();
+```
+
+More on assigning variables in [using data in templates](variables/assigning.md).
+
+
+## Testing if a template exists
+You can use `templateExists()` to check whether a template exists before you attempt to use it.
+
+It accepts either a path to the template on the filesystem or a
+resource string specifying the template.
+
+This example uses `$_GET['page']` to
+[`{include}`](../designers/language-builtin-functions/language-function-include.md) a content template. If the
+template does not exist then an error page is displayed instead. First, 
+the `page_container.tpl`

+# Template resources
+
+## The filesystem resource
+
+So far in our examples, we have used simple filenames or paths when loading a template.
+
+For example, to load a template file called `homepage.tpl`, from the filesystem, you could write:
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->display('homepage.tpl');
+```
+
+The filesystem is the default resource. Templates, however, may come 
+from a variety of sources. When you render a template, or
+when you include a template from within another template, you supply a
+resource type, followed by `:` and the appropriate path and template name.
+
+If a resource is not explicitly given, the default resource type is assumed.
+The resource type for the filesystem is `file`, which means that the previous example
+can be rewritten as follows:
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->display('file:homepage.tpl');
+```
+
+The file resource pulls templates source files from the directories
+specified using `Smarty::setTemplateDir()` (see [Configuring Smarty](configuring.md)).
+
+`setTemplateDir` accepts a single path, but can also ben called with an array of paths. 
+In that case, the list of directories is traversed in the order they appear in the array. The
+first template found is the one to process.
+
+### Templates from a specific directory
+
+Smarty 3.1 introduced the bracket-syntax for specifying an element from
+`Smarty::setTemplateDir()`. This allows websites
+employing multiple sets of templates better control over which template
+to access.
+
+The bracket-syntax can be used as follows:
+```php
+<?php

+]);

+  ./templates/foo.tpl
+  ./templates_2/foo.tpl

+// will load ./templates_10/foo.tpl
+
+// using string index
+$smarty->display('file:[foo]foo.tpl'); 
+// will load ./templates_foo/foo.tpl
+
+// using "unknown" numeric index (using element number)
+$smarty->display('file:[2]foo.tpl'); 
+// will load ./templates_10/foo.tpl
+```
+
+And, from within a Smarty template:
+
+```smarty
+{include file="file:foo.tpl"}
+{* will load ./templates/foo.tpl *}

+{* will load ./templates_2/foo.tpl *}
+
+{include file="file:[foo]foo.tpl"}
+{* will load ./templates_foo/foo.tpl *}
+```
+
+### Using absolute paths
+
+Templates outside the specified template directories 
+require the `file:` template resource type, followed by the absolute
+path to the template (with leading slash).
+
+```php
+<?php
+$smarty->display('file:/export/templates/index.tpl');
+$smarty->display('file:/path/to/my/templates/menu.tpl');
+````
+
+And from within a Smarty template:
+```smarty
+{include file='file:/usr/local/share/templates/navigation.tpl'}
+```
+
+> **Note**
+>
+> With [`Security`](security.md) enabled, access to
+> templates outside of the specified templates directories is
+> not allowed unless you whitelist those directories.
+
+### Windows file paths 
+If you are running on Windows, file paths usually include a drive
+letter (such as `C:`) at the beginning of the pathname. Be sure to use `file:` in
+the path to avoid namespace conflicts and get the desired results.
+```php
+<?php
+$smarty->display('file:C:/export/templates/index.tpl');
+$smarty->display('file:F:/path/to/my/templates/menu.tpl');
+```
+
+And from within Smarty template:
+```smarty
+{include file='file:D:/usr/local/share/templates/navigation.tpl'}
+```
+
+### Handling missing templates
+If the file resource cannot find the requested template, it will check if there is
+a default template handler to call. By default, there is none, and Smarty will return an error,
+but you can register a default template handler calling `Smarty::registerDefaultTemplateHandler`
+with any [callable](https://www.php.net/manual/en/language.types.callable.php).
+
+```php
+<?php
+
+$smarty->registerDefaultTemplateHandler([$this, 'handleMissingTemplate']);
+
+// ...
+
+public function handleMissingTemplate($type, $name, &$content, &$modified, Smarty $smarty) {
+    if (/* ... */) {
+        // return corrected filepath
+        return "/tmp/some/foobar.tpl";
+    } elseif (/* ... */) {
+        // return a template directly
+        $content = "the template source";
+        $modified = time();
+        return true;
+    } else {
+        // tell smarty that we failed
+        return false;
+    }
+}
+
+```
+
+## The string and eval resources
+
+Smarty can render templates from a string by using the `string:` or
+`eval:` resource.
+
+-   The `string:` resource behaves much the same as a template file. The
+    template source is compiled from a string and stores the compiled
+    template code for later reuse. Each unique template string will
+    create a new compiled template file. If your template strings are
+    accessed frequently, this is a good choice. If you have frequently
+    changing template strings (or strings with low reuse value), the
+    `eval:` resource may be a better choice, as it doesn\'t save
+    compiled templates to disk.
+
+-   The `eval:` resource evaluates the template source every time a page
+    is rendered. This is a good choice for strings with low reuse value.
+    If the same string is accessed frequently, the `string:` resource
+    may be a better choice.
+
+> **Note**
+>
+> With a `string:` resource type, each unique string generates a
+> compiled file. Smarty cannot detect a string that has changed, and
+> therefore will generate a new compiled file for each unique string. It
+> is important to choose the correct resource so that you do not fill
+> your disk space with wasted compiled strings.
+
+```php
+<?php
+$smarty->assign('foo', 'value');
+$template_string = 'display {$foo} here';
+$smarty->display('string:' . $template_string); // compiles for later reuse
+$smarty->display('eval:' . $template_string); // compiles every time
+```
+From within a Smarty template:
+```smarty
+{include file="string:$template_string"} {* compiles for later reuse *}
+{include file="eval:$template_string"} {* compiles every time *}
+```
+
+Both `string:` and `eval:` resources may be encoded with
+[`urlencode()`](https://www.php.net/urlencode) or
+[`base64_encode()`](https://www.php.net/urlencode). This is not necessary
+for the usual use of `string:` and `eval:`, but is required when using
+either of them in conjunction with the [`extends resource`](#the-extends-resource).
+
+```php
+ <?php
+ $smarty->assign('foo','value');
+ $template_string_urlencode = urlencode('display {$foo} here');
+ $template_string_base64 = base64_encode('display {$foo} here');
+ $smarty->display('eval:urlencode:' . $template_string_urlencode); // will decode string using urldecode()
+ $smarty->display('eval:base64:' . $template_string_base64); // will decode string using base64_decode()
+```
+
+From within a Smarty template:
+```smarty
+ {include file="string:urlencode:$template_string_urlencode"} {* will decode string using urldecode() *}
+ {include file="eval:base64:$template_string_base64"} {* will decode string using base64_decode() *}
+```
+
+## The extends resource
+
+The `extends:` resource is used to define child/parent relationships. For details see section of
+[Template inheritance](inheritance.md).
+
+> **Note**
+>
+> Using the extends resource is usually not necessary. If you have a choice, it is normally more flexible and
+> intuitive to handle inheritance chains from within the templates using the [{extends} tag](inheritance.md).
+
+When `string:` and `eval:` templates are used, make sure they are properly url or base64 encoded. 
+
+The templates within an inheritance chain are not compiled separately. Only a single compiled template will be generated. 
+(If an `eval:` resource is found within an inheritance chain, its "don't save a compile file" property is superseded by 
+the `extends:` resource.)
+
+Example:
+```php
+<?php
+$smarty->display('extends:parent.tpl|child.tpl|grandchild.tpl'); 
+
+// inheritance from multiple template sources
+$smarty->display('extends:db:parent.tpl|file:child.tpl|grandchild.tpl|eval:{block name="fooBazVar_"}hello world{/block}'); 
+```
+
+## The stream resource
+
+Smarty allow you to use [PHP streams](https://www.php.net/manual/en/function.stream-wrapper-register.php) 
+as a template resource. Smarty will first look for a registered template resource. If nothing is
+found, it will check if a PHP stream is available.  If a stream is available, Smarty will use it 
+to fetch the template.
+
+For example, 
+```php
+<?php
+stream_wrapper_register('myresource', MyResourceStream::class);
+$smarty->display('myresource:bar.tpl');
+```
+
+Or, from within a template:
+```smarty
+ {include file="myresource:bar.tpl"}
+```
+
+## Adding your own resource type
+You can create a class that extends `Smarty\Resource\CustomPlugin` to add your own resource type, 
+for example to load template from a database.
+
+For example:
+```php
+<?php
+class HelloWorldResource extends Smarty\Resource\CustomPlugin {
+
+    protected function fetch($name, &$source, &$mtime) {
+        $source = '{$x="hello world"}{$x}'; // load your template here based on $name
+        $mtime = time();
+    }
+
+}
+
+// ..
+
+$smarty->registerResource('helloworld', new HelloWorldResource());
+```
+
+If a Resource's templates should not be run through the Smarty
+compiler, the Custom Resource may extend `\Smarty\Resource\UncompiledPlugin`.
+The Resource Handler must then implement the function
+`renderUncompiled(\Smarty\Template $_template)`. `$_template` is
+a reference to the current template and contains all assigned variables
+which the implementor can access via
+`$_template->getSmarty()->getTemplateVars()`. These Resources simply echo
+their rendered content to the output stream. The rendered output will be
+output-cached if the Smarty instance was configured accordingly. See
+`src/Resource/PhpPlugin.php` for an example.
+
+If the Resource's compiled templates should not be cached on disk, the
+Custom Resource may extend `\Smarty\Resource\RecompiledPlugin`. These Resources
+are compiled every time they are accessed. This may be an expensive
+overhead. See `src/Resource/StringEval.php` for an
+example.
+
+## Changing the default resource type
+The default resource type is `file`. If you want to change it, use `Smarty::setDefaultResourceType`.
+
+The following example will change the default resource type to `mysql`:
+```php
+<?php
+$smarty->setDefaultResourceType('mysql');
+```

+# Security
+
+Security is good for situations when you have untrusted parties editing
+the templates, and you want to reduce the risk of system
+security compromises through the template language.
+
+The settings of the security policy are defined by overriding public properties of an
+instance of the \Smarty\Security class. These are the possible settings:
+
+- `$secure_dir` is an array of template directories that are
+    considered secure. A directory configured using `$smarty->setTemplateDir()` is
+    considered secure implicitly. The default is an empty array.
+- `$trusted_uri` is an array of regular expressions matching URIs that
+  are considered trusted. This security directive is used by
+  [`{fetch}`](../designers/language-custom-functions/language-function-fetch.md) and
+  [`{html_image}`](../designers/language-custom-functions/language-function-html-image.md). URIs passed to
+  these functions are reduced to `{$PROTOCOL}://{$HOSTNAME}` to allow
+  simple regular expressions (without having to deal with edge cases
+  like authentication-tokens).
+
+  The expression `'#https?://.*smarty.net$#i'` would allow accessing
+  the following URIs:
+
+    -   `http://smarty.net/foo`
+    -   `http://smarty.net/foo`
+    -   `http://www.smarty.net/foo`
+    -   `http://smarty.net/foo`
+    -   `https://foo.bar.www.smarty.net/foo/bla?blubb=1`
+
+  but deny access to these URIs:
+
+    -   `http://smarty.com/foo` (not matching top-level domain \"com\")
+    -   `ftp://www.smarty.net/foo` (not matching protocol \"ftp\")
+    -   `http://www.smarty.net.otherdomain.com/foo` (not matching end of
+        domain \"smarty.net\")
+
+-   `$static_classes` is an array of classes that are considered
+    trusted. The default is an empty array which allows access to all
+    static classes. To disable access to all static classes set
+    $static_classes = null.
+
+-   `$streams` is an array of streams that are considered trusted and
+    can be used from within template. To disable access to all streams
+    set $streams = null. An empty array ( $streams = [] ) will
+    allow all streams. The default is array('file').
+
+-   `$allowed_modifiers` is an array of (registered / autoloaded)
+    modifiers that should be accessible to the template. If this array
+    is non-empty, only the herein listed modifiers may be used. This is
+    a whitelist.
+
+-   `$disabled_modifiers` is an array of (registered / autoloaded)
+    modifiers that may not be accessible to the template.
+
+-   `$allowed_tags` is a boolean flag which controls if constants can
+    function-, block and filter plugins that should be accessible to the
+    template. If this array is non-empty, only the herein listed
+    modifiers may be used. This is a whitelist.
+
+-   `$disabled_tags` is an array of (registered / autoloaded) function-,
+    block and filter plugins that may not be accessible to the template.
+
+-   `$allow_constants` is a boolean flag which controls if constants can
+    be accessed by the template. The default is "true".
+
+-   `$allow_super_globals` is a boolean flag which controls if the PHP
+    super globals can be accessed by the template. The default is
+    "true".
+
+If security is enabled, no private methods, functions or properties of
+static classes or assigned objects can be accessed (beginning with
+'_') by the template.
+
+To customize the security policy settings you can extend the
+\Smarty\Security class or create an instance of it.
+
+```php
+<?php
+
+use Smarty\Smarty;
+
+class My_Security_Policy extends \Smarty\Security {
+  public $allow_constants = false;
+}
+
+$smarty = new Smarty();

+# Assigning variables
+
+Templates start to become really useful once you know how to use variables.
+
+## Basic assigning
+Let's revisit the example from the [basics section](../basics.md). The following script assigns a value to 
+the 'companyName' variable and renders the template:
+
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$smarty->assign('companyName', 'AC & ME Corp.');
+
+$smarty->display('footer.tpl');
+```
+
+footer.tpl:
+```smarty
+<small>Copyright {$companyName|escape}</small>
+```
+
+Smarty will apply the [escape modifier](../../designers/language-modifiers/language-modifier-escape.md)
+to the value assigned to the variable
+`companyName` and replace `{$companyName|escape}` with the result.
+
+```html
+<small>Copyright AC &amp; ME Corp.</small>
+```
+
+Using `$smarty->assign()` is the most common way of assigning data to templates, but there are several other methods.
+
+## Appending data to an existing variable
+Using `append()`, you can add data to an existing variable, usually an array.
+
+If you append to a string value, it is converted to an array value and
+then appended to. You can explicitly pass name/value pairs, or
+associative arrays containing the name/value pairs. If you pass the
+optional third parameter of TRUE, the value will be merged with the
+current array instead of appended.
+
+Examples:
+
+```php
+<?php
+// This is effectively the same as assign()
+$smarty->append('foo', 'Fred');
+// After this line, foo will now be seen as an array in the template
+$smarty->append('foo', 'Albert');
+
+$array = [1 => 'one', 2 => 'two'];
+$smarty->append('X', $array);
+$array2 = [3 => 'three', 4 => 'four'];
+// The following line will add a second element to the X array
+$smarty->append('X', $array2);
+
+// passing an associative array
+$smarty->append(['city' => 'Lincoln', 'state' => 'Nebraska']);
+```
+
+## Assigning to template objects
+When you use a template objects, as explained in [rendering a template](../rendering.md#creating-a-template-object),
+you can assign data to the template objects directly instead of assigning it to Smarty. This way, you can use different
+sets of data for different templates.
+
+For example:
+```php
+<?php
+
+use Smarty\Smarty;
+$smarty = new Smarty();
+
+$tplBlue = $smarty->createTemplate('blue.tpl');
+$tplBlue->assign('name', 'The one');
+$tplBlue->display();
+
+$tplRed = $smarty->createTemplate('red.tpl');
+$tplRed->assign('name', 'Neo');
+$tplRed->display();
+```
+
+## Using data objects
+For more complex use cases, Smarty supports the concept of data objects.
+Data objects are containers to hold data. Data objects can be attached to templates when creating them.
+This allows for fine-grained re-use of data.
+
+For example:
+```php
+<?php
+use Smarty\Smarty;
+$smarty = new Smarty;
+
+// create a data object
+$data = $smarty->createData();
+
+// assign variable to the data object
+$data->assign('name', 'Neo');
+
+// create template object which will use variables from the data object
+$tpl = $smarty->createTemplate('index.tpl', $data);
+
+// display the template
+$tpl->display();
+```
+
+## Clearing assigned data
+When re-using templates, you may need to clear data assigned in a previous run. Use `clearAllAssign()` to 
+clear the values of all assigned variables on data objects, template objects or the Smarty object.
+
+Examples:
+```php
+<?php
+// assigning data to the Smarty object
+$smarty->assign('Name', 'Fred');
+// ...
+$smarty->clearAllAssign();
+
+// using a data object
+$data = $smarty->createData();
+$data->assign('name', 'Neo');
+// ...
+$data->clearAllAssign();
+
+// using a template
+$tplBlue = $smarty->createTemplate('blue.tpl');
+$tplBlue->assign('name', 'The one');
+// ...
+$tplBlue->clearAllAssign();
+```
+
+Note that there it's only useful to clear assigned data if you:
+
+1. repeatedly re-use templates, and
+2. the variables used may change on each repetition
+
+If your script simply runs once and then ends, or you always assign the same variables, clearing assigned data 
+is of no use.

+# Loading data from config files
+
+Instead of [assigning data to templates from PHP](assigning.md), you can also
+use a config file.
+
+## Example config file
+Config files are best suited to manage template settings
+from one file. One example is a multi-language application.
+Instead of writing multiple templates to support different languages, 
+you can write a single template file and load your language dependent strings
+from config files.
+
+Example `lang.en.ini`:
+```ini
+# global variables
+pageTitle = "Main Menu"
+
+[Customer]
+pageTitle = "Customer Info"
+
+[Login]
+pageTitle = "Login"
+focus = "username"
+Intro = """This is a value that spans more
+           than one line. you must enclose
+           it in triple quotes."""
+
+```
+
+Values of [config file variables](../../designers/language-variables/language-config-variables.md) can be in
+quotes, but not necessary. You can use either single or double quotes.
+If you have a value that spans more than one line, enclose the entire
+value with triple quotes \("""\). You can put comments into config
+files by any syntax that is not a valid config file syntax. We recommend
+using a `#` (hash) at the beginning of the line.
+
+The example config file above has two sections. Section names are
+enclosed in \[brackets\]. Section names can be arbitrary strings not
+containing `[` or `]` symbols. The variable at the top is a global
+variable. Global variables are always
+loaded from the config file. If a particular section is loaded, then the
+global variables and the variables from that section are also loaded. If
+a variable exists both as a global and in a section, the section
+variable is used.
+
+## Loading a config file
+
+Config files are loaded into templates with the built-in template
+function [`{config_load}`](../../designers/language-builtin-functions/language-function-config-load.md) or by calling
+`configLoad()` from PHP:
+
+```php
+<?php
+$smarty->configLoad('lang.en.ini');
+```
+
+Load a specific section with:
+
+```php
+<?php
+$smarty->configLoad('lang.en.ini', 'Customer');
+```
+
+Note that the global section will always be loaded.
+
+## Retrieving config variables in PHP
+
+
+## Loading from a resource
+Config files (or resources) are loaded by the same resource facilities
+as templates. That means that a config file can also be loaded from a db. See [resources](../resources.md)
+for more information.
+
+## Config overwrite
+If you name two variables the same within a section,
+the last one will be used unless you call:
+```php
+<?php
+$smarty->setConfigOverwrite(false);
+```
+When config overwrite is disabled, Smarty will create arrays of config file variables when it encounters
+multiple entries with the same name.
+
+See also [`{config_load}`](../../designers/language-builtin-functions/language-function-config-load.md),

+# Objects
+
+Smarty allows access to PHP [objects](https://www.php.net/object) through
+the templates.
+
+> **Note**
+>
+> When you assign/register objects to templates, be sure that all
+> properties and methods accessed from the template are for presentation
+> purposes only. It is very easy to inject application logic through
+> objects, and this leads to poor designs that are difficult to manage.
+> See the Best Practices section of the Smarty website.
+
+There are two ways to access them.
+
+## Assign the object
+You can assign objects to a template and access them much like any other assigned variable.
+
+Example:
+```php
+<?php
+// the object
+
+class My_Object {
+    public function meth1($params, $smarty_obj) {
+        return 'this is my meth1';
+    }
+}
+
+// We can also assign objects. assign_by_ref when possible.
+$smarty->assign('myobj', new My_Object());
+
+$smarty->display('index.tpl');
+```
+
+And here's how to access your object in `index.tpl`:
+
+```smarty
+{$myobj->meth1('foo',$bar)}
+```
+
+
+
+## Register the object
+Registerd objects use a different template syntax. Also, a registered object 
+can be restricted to certain methods or
+properties. However, **a registered object cannot be looped over or
+assigned in arrays of objects**, etc.
+
+If security is enabled, no private methods or functions can be accessed
+(beginning with '_'). If a method and property of the same name exist,
+the method will be used.
+
+You can restrict the methods and properties that can be accessed by
+listing them in an array as the third registration parameter.
+
+By default, parameters passed to objects through the templates are
+passed the same way [custom tags](../../designers/language-custom-functions/index.md) get
+them. An associative array is passed as the first parameter, and the
+smarty object as the second. If you want the parameters passed one at a
+time for each argument like traditional object parameter passing, set
+the fourth registration parameter to FALSE.
+
+The optional fifth parameter has only effect with `format` being TRUE
+and contains a list of methods that should be treated as blocks. That
+means these methods have a closing tag in the template
+(`{foobar->meth2}...{/foobar->meth2}`) and the parameters to the methods
+have the same synopsis as the parameters for
+[`block tags`](../extending/block-tags.md): They get the four
+parameters `$params`, `$content`, `$smarty` and `&$repeat` and they also
+behave like block tags.
+
+```php
+<?php
+// the object
+
+class My_Object {
+    function meth1($params, $smarty_obj) {
+        return 'this is my meth1';
+    }
+}
+
+$myobj = new My_Object;
+
+// registering the object
+$smarty->registerObject('foobar', $myobj);
+
+// if we want to restrict access to certain methods or properties, list them
+$smarty->registerObject('foobar', $myobj, array('meth1','meth2','prop1'));
+
+// if you want to use the traditional object parameter format, pass a boolean of false
+$smarty->registerObject('foobar', $myobj, null, false);
+
+$smarty->display('index.tpl');
+```
+
+And here's how to access your objects in `index.tpl`:
+
+```smarty
+{* access our registered object *}
+{foobar->meth1 p1='foo' p2=$bar}
+
+{* you can also assign the output *}
+{foobar->meth1 p1='foo' p2=$bar assign='output'}
+the output was {$output}

+# Static Classes
+
+You can directly access static classes. The syntax is roughly the same as in
+PHP.

+> **Note**

+> Direct access to PHP classes is not recommended. This ties the

 `mainpage.tpl` - When the main page is drawn, the title of "Main Page"
 is passed to the `header.tpl`, and will subsequently be used as the
 title.

 `archives.tpl` - When the archives page is drawn, the title will be
 "Archives". Notice in the archive example, we are using a variable from
 the `archives_page.conf` file instead of a hard coded variable.

-Dates {#tips.dates}

+## Dates

 As a rule of thumb, always pass dates to Smarty as
-[timestamps](&url.php-manual;time). This allows template designers to
-use the [`date_format`](#language.modifier.date.format) modifier for
+[timestamps](https://www.php.net/time). This allows template designers to
+use the [`date_format`](../designers/language-modifiers/language-modifier-date-format.md) modifier for
 full control over date formatting, and also makes it easy to compare
 dates if necessary.

-
-    {$startDate|date_format}
-
+```smarty
+{$startDate|date_format}
+```
        

 This will output:

+```
+Jan 4, 2009
+```

-    Jan 4, 2009
+```smarty

-        
-
-
-    {$startDate|date_format:"%Y/%m/%d"}
+{$startDate|date_format:"%Y/%m/%d"}

 This will output:

-
-    2009/01/04
-

+```

 Dates can be compared in the template by timestamps with:

+```smarty

-    {if $order_date < $invoice_date}
-       ...do something..
-    {/if}

+
+## Ternary
+You can use the `?:` (or ternary) operator to test one expression and present the value
+of the second or third expression, based on the result of the test.
+
+In other words:
+```smarty
+{$test ? "OK" : "FAIL"}
+```
+will result in OK if `$test` is set to true, and in FAIL otherwise.
+
+There is also a shorthand `?:` operator:
+```smarty
+{$myVar ?: "empty"}
+```
+will result in 'empty' if `$myVar` is not set or set to something that evaluates to false, such as an empty string.
+If `$myVar` is set to something that evaluates to true, the value of `$myVar` is returned. So, the following will 
+return 'hello':
+```smarty
+{$myVar="hello"}
+{$myVar ?: "empty"}
+```
+
+## Testing for null
+If "something that evaluates to false" is to broad a test for you, you can use the `??` (or null coalescing) operator 
+to trigger only if the tested value is undefined or set to null.
+```smarty
+{$myVar ?? "empty"}
+```
+will result in 'empty' if `$myVar` is not set or set to null.
+If `$myVar` is set to something that evaluates to anything else, the value of `$myVar` is returned. So, the following will

-Let\'s say you have a template with a banner slot at the top of the
-page. The banner can contain any mixture of HTML, images, flash, etc. so
-we can\'t just use a static link here, and we don\'t want this contents
-cached with the page. In comes the {insert} tag: the template knows
-\#banner\_location\_id\# and \#site\_id\# values (gathered from a
-[config file](#config.files)), and needs to call a function to get the
-banner contents.
-
-    {* example of fetching a banner *}
-    {insert name="getBanner" lid=#banner_location_id# sid=#site_id#}
-    {insert "getBanner" lid=#banner_location_id# sid=#site_id#} {* short-hand *}
-
-In this example, we are using the name "getBanner" and passing the
-parameters \#banner\_location\_id\# and \#site\_id\#. Smarty will look
-for a function named insert\_getBanner() in your PHP application,
-passing the values of \#banner\_location\_id\# and \#site\_id\# as the
-first argument in an associative array. All {insert} function names in
-your application must be prepended with \"insert\_\" to remedy possible
-function name-space conflicts. Your insert\_getBanner() function should
-do something with the passed values and return the results. These
-results are then displayed in the template in place of the {insert} tag.
-In this example, Smarty would call this function:
-insert\_getBanner(array(\"lid\" =\> \"12345\",\"sid\" =\> \"67890\"));
-and display the returned results in place of the {insert} tag.
-
-   If you supply the `assign` attribute, the output of the `{insert}`
-    tag will be assigned to this template variable instead of being
-    output to the template.
-
-    > **Note**
-    >
-    > Assigning the output to a template variable isn\'t too useful with
-    > [caching](#variable.caching) enabled.
-
-   If you supply the `script` attribute, this php script will be
-    included (only once) before the `{insert}` function is executed.
-    This is the case where the insert function may not exist yet, and a
-    php script must be included first to make it work.
-
-    The path can be either absolute, or relative to
-    [`$trusted_dir`](#variable.trusted.dir). If security is enabled,
-    then the script must be located in the `$trusted_dir` path of the
-    security policy. See the [Security](#advanced.features.security)
-    section for details.
-
-The Smarty object is passed as the second argument. This way you can
-reference and modify information in the Smarty object from within the
-`{insert}` function.
-
-If no PHP script can be found Smarty is looking for a corresponding
-insert plugin.

+# {counter}

 `{counter}` is used to print out a count. `{counter}` will remember the
 count on each iteration. You can adjust the number, the interval and the
-direction of the count, as well as determine whether or not to print the
+direction of the count, as well as determine whether to print the
 value. You can run multiple counters concurrently by supplying a unique
 name for each one. If you do not supply a name, the name "default" will
 be used.

- Modifiers are autoloaded from the

-
- All php-functions can be used as modifiers implicitly, as
-    demonstrated in the example above. However, using php-functions as
-    modifiers has two little pitfalls:
-
-    -   First - sometimes the order of the function-parameters is not
-        the desirable one. Formatting `$foo` with
-        `{"%2.f"|sprintf:$foo}` actually works, but asks for the more
-        intuitive, like `{$foo|string_format:"%2.f"}` that is provided
-        by the Smarty distribution.
-
-    -   Secondly - if security is enabled, all php-functions that are to
-        be used as modifiers have to be declared trusted in the
-        `$modifiers` property of the security policy. See the
-        [Security](../programmers/advanced-features/advanced-features-security.md) section for details.

+# Variable Modifiers
+
+Variable modifiers can be applied to
+[variables](../language-variables/index.md), [custom tags](../language-custom-functions/index.md)
+or strings. To apply a modifier,
+specify the value followed by a `|` (pipe) and the modifier name. A
+modifier may accept additional parameters that affect its behavior.
+These parameters follow the modifier name and are separated by a `:`
+(colon). Also, *all php-functions can be used as modifiers implicitly*
+(more below) and modifiers can be
+[combined](../language-combining-modifiers.md).

Inlined Cached::create into its only caller. Some other minor improvements.

Provided a getter/setter for the has_nocache_code property. Removed the useless DataObject class. Fixed a few tests. Removed the variable-allow-php-templates property from the docs. * Simplified the (no)caching architecture by: - removing support for $cache_attrs for registered plugins, - removing the undocumented {make_nocache} tag and the deprecated {insert} tag and associated code - removing support for a compile_id property on include tags. Fixes a bug in extends: resources by propagating the nocache-hashes between a master template and it's subtemplates in \Smarty\Template::_subTemplateRender. This might need further improvement. * Removed unneeded magic setters/getters/destructors and the like. * Replaced a bunch of direct property access with getters/setters. * Update test runners: no longer support PHP7.1, add PHP8.2 * Fixed scope in variable assignments in included and extended templates, fixed dependencies for testing freshness of caches. Added some unit tests and fixed a class reference to pass some more tests. * Fix searchParents parameter, fixing GetTemplateVarsTest * @var integer > @var int for vsCode * Fix function caching function name * Fixed cacheability of block plugins. * Moved handling of smarty.block.* to special compilers, because they aren't real tags. Organized tag-stack handling in compiler, unified nocache handling in compiler. * Fixed block append/prepend functionality * Fix testRegisterCompilerFunction by parsing argument correctly. * Made exception msgs exactly the same again, fixing some unit tests * Fix default plugin handler * Simply the "isFresh" method by not including the first param anymore. Fix a couple of unit tests by respecting tag_nocache set by nocache vars used in a tag. * Removed the undocumented {block_parent} and {parent} alternatives to {$smarty.block.parent} and {block_child} and {child} alternatives to {$smarty.block.child} * Fix inhertiance implementation for $smarty.block.child * Fixed all inheritance issues * Handle BC registered compilers and missed parameters for openTag and closeTag. * Fix all foreach unit tests * Fixed the {if} failures. * Fix major {include} bug * Fixed bug in {include} variable assignment and removed some unused/unrequired code * Fix function call compilation using {functionname} syntax for in-template defined functions. * Drop a unit tests bc we no longer support direct access to PHP-functinos such as sin() * Fixed all scope assignment bugs * Convert isset and empty to modifiercomilers, and smooth the error handling to fix unit tests. * Fixed getCachedContent * Add TODO list * Run composer install before online test run * Attempt to fix CI * revise CI/CD workflows, bypass packagist for lexer * Update ci.yml * Update ci.yml * fixes in source files * Update ci.yml * Update ci.yml * attempt to load smarty-lexer directly from zip file * Shouldnt need Github token now * correct type of repository * Updated the changelog * Re-organized rendering (read source / compile / cache) process to avoid circular dependencies. Deactivated merge_compiled_includes and the {include inline} attribute. They don't seem to do much in terms of performance, but we'll have to check back. * updated todo * Fix smarty-lexer dependency for the time being * Fix smarty-lexer dependency for the time being (remove direct ref to github) * Pushed Lexers/Parsers into VCS again in order to be able to deliver using Packagist/Composer * Re-organized rendering (read source / compile / cache) process to avoid circular dependencies. * Run make regardless of timestamps, so we are sure unit tests run with the generated PHP code, not with accidental human made changes to Lexer/Parser. * Update composer packages cache key Update composer packages cache key to trigger refresh on lexer * 4.0.2 of smarty-lexer is released, use that * Throw compile error when using a modifier where it won't work. Fixes #526. * verify that native PHP functions cannot be used as a modifier and verify that an easy userland workaround exists. Fixes #813. * Add test for registering compiler plugin with positional params. Fixes #164 * move test methods because some other test methods rely on their relative positions * Smarty no longer calls `mb_internal_encoding()` and doesn't check for deprecated `mbstring.func_overload` ini directive. Fixes #480. * Generated `<script>` tags lo longer have deprecated `type="text/javascript"` or `language="Javascript"` attributes. Fixes #815. * Fix error in docs on prepend/append. Fixes #818. * Move all creating of templates to Smarty::createTemplate, adding a private property containing previously generated templates for speed. * Load compiled object in template constructor so it will be cached. * WIP for performance improvements. Removed $smarty->_current_file and $smarty->allow_ambiguous_resources properties, both unused. Removed public Source::filepath property. Cached an Compiled files (and Exceptions) no longer rely on the filepath being set. Removed explicit tests for cached and compiled filenames. The exact implementation is not important. Added tests for compile_check property, fixing a file_exists check that would always be done on source template files, even when compile_check was true. Remove code duplication between Source en Config classes. Added a local $_smarty_current_dir to the generated code files for backwards compatability for {$smarty.current_dir}. * remove additional calls to getCached() * updated todo * Add mkdocs for docs * add missing folder for unit tests * Revert latest CI changes, we'll update docs by hand for now * multiversion mkdocs config * fixes to docs * WIP improving the docs * Improved another chunk of the designers docs * Finished improving designers docs * Update code examples to use Smarty\Smarty and autoload instead of require_once calls and new Smarty * Further WIP improving docs * Updated changelog and todo list * WIP on API docs * WIP docs (added page on config) * Fixed markdown syntax. Fixes #879 * Added full support and documentation for ternary operator. Fixes #881 * updated changelog * fixed error in the mkdocs TOC * Added support for null coalescing operator Fixes #882 * Add docs for null coalescing * more docs * Improved docs on compile checking and inheritance * Rewrote docs on filters and resources. * Add makefile entries for generating docs * Docs on caching * finished docs on security and extending smarty * Added Smarty::setExtensions(), fixed unit test for the null coalescing operator. Updated docs about registering a custom extension. * updated todos * fix template invalidation when migrating to 5.0	2023-08-08 00:04:14 +02:00
