-
-## Project
-
-Smarty v5 — PHP template engine. Single Composer package (`smarty/smarty`), namespace `Smarty\`, source in `src/`, autoloaded via PSR-4. Supports PHP 7.2–8.5.
-
-Do not use PHP syntax newer than 7.2 in `src/` unless it is guarded for older runtimes.
-
-## Commands
-
-```bash
-# Install dependencies
-composer install
-
-# Regenerate lexers and parsers (required before tests; CI runs this)
-make -B
-
-# Run all tests
-php ./vendor/phpunit/phpunit/phpunit
-
-# Run a single test file
-php ./vendor/phpunit/phpunit/phpunit tests/UnitTests/TemplateSource/TagTests/If/CompileIfTest.php
-
-# Run tests matching a PHPUnit group
-php ./vendor/phpunit/phpunit/phpunit --group 20221124
-
-# Run tests excluding slow group
-php ./vendor/phpunit/phpunit/phpunit --exclude-group slow
-```
-
-There is no linter or static analysis configured. No typecheck step.
-
-## Generated code — do not hand-edit
-
-Four files are generated from grammar/lexer definitions via `make`:
-
-| Source (edit this) | Generated (do not edit) |
-|---|---|
-| `src/Lexer/TemplateLexer.plex` | `src/Lexer/TemplateLexer.php` |
-| `src/Lexer/ConfigfileLexer.plex` | `src/Lexer/ConfigfileLexer.php` |
-| `src/Parser/TemplateParser.y` | `src/Parser/TemplateParser.php` |
-| `src/Parser/ConfigfileParser.y` | `src/Parser/ConfigfileParser.php` |
-
-After editing a `.plex` or `.y` file, run `make -B` to regenerate. The generators require the `smarty/smarty-lexer` dev dependency.
-
-## Architecture
-
- `src/Smarty.php` — main class, extends `TemplateBase`. Version constant: `Smarty::SMARTY_VERSION`.
- `src/Compile/`, `src/Compiler/` — template compilation pipeline.
- `src/Lexer/`, `src/Parser/` — lexer/parser (generated, see above).
- `src/Extension/` — extension system (`ExtensionInterface`, `CoreExtension`, `DefaultExtension`, `BCPluginsAdapter`).
- `src/Runtime/` — runtime helpers (foreach, capture, inheritance, tpl functions).
- `src/Resource/`, `src/Cacheresource/` — template resource and cache resource handlers.
- `src/BlockHandler/`, `src/FunctionHandler/`, `src/Filter/` — built-in tags, functions, and filters.
- `libs/Smarty.class.php` — non-Composer autoload stub. Points to `src/`. Not the main source.
- `src/functions.php` — global helper functions, always loaded via Composer `files` autoload.
-
-## Tests
-
- Framework: PHPUnit 7.5/8.5 (bootstrap: `tests/Bootstrap.php`).
- All tests extend `PHPUnit_Smarty` (defined in `tests/PHPUnit_Smarty.php`), which provides `setUpSmarty($dir)`.
- Test suite root: `tests/UnitTests/`. Typical test `setUp()` calls `$this->setUpSmarty(__DIR__)`.
- Each test directory may have its own `templates/`, `configs/` subdirectories. Compiled output goes to `templates_c/` and `cache/` (auto-created by the test harness).
- Running the suite scatters generated `templates_c/`, `cache/`, and `templates_tmp/` directories (and empty runtime `templates/`/`configs/` dirs) throughout `tests/` and the repo root. These are not tracked — treat them as noise in `git status`, never commit them, and clean them with `git clean -fd` (exclude tool dirs like `.serena`).
- Three test files are excluded in `phpunit.xml`: Memcache, APC, and HttpModifiedSince tests (require external services).
- Tests needing MySQL/PDO are gated by constants in `tests/Config.php` (disabled by default).
-
-## CI
-
-GitHub Actions (`.github/workflows/ci.yml`): matrix of PHP 7.2–8.5 on ubuntu + windows. Steps: `composer install` → `make -B` → `phpunit`. No deploy step.
-
-## Docs
-
-Markdown in `docs/`, built with mkdocs + Material theme. Install the toolchain with `pip install -r docs/requirements.txt`, then preview with `mkdocs serve`. Published via `mike deploy 5.x`.
-
-## Release
-
-`./make-release.sh <version>` — only v5.x.x. Updates changelog and version constant, creates a merge commit and tag on `master`.
-
-### Changelog
-
-Every change that should appear in `CHANGELOG.md` must add a new markdown file under `changelog/`. At release time `utilities/update-changelog.php` concatenates all `changelog/*.md` files into the `## [Unreleased]` section, so:
-
- One file per change, containing a single line that starts with a dash (`- ...`). The filename is arbitrary; name it after the issue number (e.g. `1036.md`) when there is one, otherwise use a short descriptive slug.
- Include a markdown link to the relevant issue when one exists, e.g. `[#1036](https://github.com/smarty-php/smarty/issues/1036)`. Omit the link when there is no public issue (e.g. embargoed security reports).

 ## [Unreleased]

-## [5.8.3] - 2026-06-28
- fixed a regression from #1189 where a child template's block override no longer applied to a template {include}d by the parent [#1192](https://github.com/smarty-php/smarty/issues/1192)
-
-
-## [5.8.2] - 2026-06-24
- Security: prevent symlinks inside a trusted `secure_dir`/template directory from being used to read files outside of it (CWE-22 path traversal), affecting `{include}` and `{fetch}` of local files
- Security: `{html_image}` now escapes the `file`, `path_prefix`, `href`/`link`, `width` and `height` attributes (it already escaped `alt` and pass-through attributes), and `{html_select_date}` casts `day_size`/`month_size`/`year_size` to int (matching `{html_select_time}`), preventing untrusted values passed into these attributes from breaking out of the generated HTML (CWE-79)
- Security: `{fetch}` no longer follows HTTP redirects for remote resources while a security policy is active, preventing an open redirect on a trusted host from bypassing `trusted_uri` (CWE-918 server-side request forgery)
- Fixed "Attempt to assign property step on null" error when using a {for} loop inside a block of an extended template [#1036](https://github.com/smarty-php/smarty/issues/1036)
-

-## Regex Matching Operator
-
-The `matches` operator allows you to test if a string matches a regular expression pattern.
-
-### Basic Usage
-
-```smarty
-{if "hello" matches "/^[a-z]+$/"}
-    String matches the pattern!
-{/if}
-
-{if $email matches "/^[^@]+@[^@]+\.[^@]+$/"}
-    Valid email format
-{else}
-    Invalid email format
-{/if}
-```
-
-### Using Variables
-
-```smarty
-{$pattern = '/^[a-zA-Z0-9]{8,}$/'}
-{if $password matches $pattern}
-    Password meets requirements
-{else}
-    Password must be at least 8 alphanumeric characters
-{/if}
-```
-
-### Pattern Modifiers
-
-The `matches` operator supports all standard PHP regex modifiers:
-
-```smarty
-{* Case insensitive matching *}
-{if "HELLO" matches "/hello/i"}
-    Matches (case insensitive)
-{/if}
-
-{* Multiline mode *}
-{if "line1\nline2" matches "/line2$/m"}
-    Matches in multiline mode
-{/if}
-
-{* Dot matches newlines *}
-{if "hello\nworld" matches "/hello.world/s"}
-    Matches with dotall modifier
-{/if}
-```
-
-### Complex Conditions
-
-The `matches` operator can be combined with other operators:
-
-```smarty
-{if $username matches "/^[a-z]+$/" && $username|length > 3}
-    Valid username
-{else}
-    Username must be lowercase letters and at least 4 characters
-{/if}
-
-{if $input matches "/^[0-9]+$/" || $input matches "/^[a-z]+$/"}
-    Input is either numeric or lowercase letters
-{else}
-    Invalid input format
-{/if}
-```
-
-### Practical Examples
-
-**Email Validation:**
-```smarty
-{if $email matches "/^[^@\s]+@[^@\s]+\.[^@\s]+$/"}
-    Valid email address
-{else}
-    Please enter a valid email address
-{/if}
-```
-
-**Password Strength:**
-```smarty
-{if $password matches "/^(?=.*[a-z])(?=.*[A-Z])(?=.*\d).{8,}$/"}
-    Strong password
-{else}
-    Password must contain uppercase, lowercase, numbers and be at least 8 characters
-{/if}
-```
-
-**URL Validation:**
-```smarty
-{if $url matches "/^https?:\/\/(www\.)?[a-z0-9\-]+(\.[a-z]{2,})+/i"}
-    Valid URL format
-{else}
-    Please enter a valid URL
-{/if}
-```
-
-**Numeric Validation:**
-```smarty
-{if $input matches "/^[0-9]+$/"}
-    Valid numeric input
-{else}
-    Please enter numbers only
-{/if}
-```
-
-### Notes
-
- The `matches` operator uses PHP's `preg_match()` function internally
- Pattern delimiters must be valid regex delimiters (typically `/`)
- Invalid patterns will cause PHP warnings but won't break template execution
- For complex regex patterns, consider using variables for better readability

-Smarty supports accessing properties of [backed enums](https://www.php.net/manual/en/language.enumerations.backed.php) introduced in PHP 8.1.
-
-### Accessing Enum Properties
-
-You can access the `name` and `value` properties of backed enum cases:
-
-```smarty
-{* Access enum case properties *}
-<option id="{MyEnum::Foo->name}">{MyEnum::Foo->value}</option>
-```
-
-### Complete Example
-
-```php
-<?php
-use Smarty\Smarty;
-
-// Define a backed enum
-enum Status: string {
-    case Active = 'active';
-    case Inactive = 'inactive';
-    case Pending = 'pending';
-}
-
-$smarty = new Smarty();
-$smarty->assign('currentStatus', Status::Active);
-$smarty->display('template.tpl');
-```
-
-`template.tpl`:
-
-```smarty
-{* Display enum properties *}
-Current status: {$currentStatus->name} (value: {$currentStatus->value})
-
-{* Use in HTML attributes *}
-<select name="status">
-    <option value="{Status::Active->value}" {if $currentStatus->name === 'Active'}selected{/if}>Active</option>
-    <option value="{Status::Inactive->value}" {if $currentStatus->name === 'Inactive'}selected{/if}>Inactive</option>
-    <option value="{Status::Pending->value}" {if $currentStatus->name === 'Pending'}selected{/if}>Pending</option>
-</select>
-```
-
-This would output:
-
-```html
-Current status: Active (value: active)
-
-<select name="status">
-    <option value="active" selected>Active</option>
-    <option value="inactive">Inactive</option>
-    <option value="pending">Pending</option>
-</select>
-```
-
-### Integer-backed Enums
-
-Integer-backed enums work the same way:
-
-```php
-<?php
-enum Priority: int {
-    case Low = 1;
-    case Medium = 2; 
-    case High = 3;
-}
-
-$smarty->assign('priority', Priority::High);
-```
-
-```smarty
-{* Access integer enum properties *}
-Priority level: {$priority->value} ({$priority->name})
-```
-
-Output:
-
-```html
-Priority level: 3 (High)
-```
-
-> **Note**: Backed enum support requires PHP 8.1 or higher. The enum must be registered or available in the current namespace.

-#### Passing parameters by reference
-You cannot use plugins that expect a parameter by reference anymore. PHP-function such as `reset()`, `prev()`, 
-`next()` and `end()` can be registered as plugin, but they won't work because they expect a parameter by

 ### Removed undocumented tags

 Smarty 4 still supported some tags that have been carried over from previous version, but have never been documented.

 - `$smarty->assignByRef()` should be replaced with `$smarty->assign()`
 - `$smarty->loadPlugin()` should be replaced with `$smarty->registerPlugin()`

-### Removed undocumented magic API methods
-
-Smarty v4 allowed setting (internal) properties for which no setter existed by using magic methods 
-that start with either `set` or `get`. This has been removed in Smarty 5.
-
-For example, `$smarty->setErrorUnassigned(true);` would set the `error_unassigned` property.

-Every setter of getter that was ever documented or unit tested has been kept.

 ### Removed PHP constants

				- Security: the built-in `stream:` resource type now validates the nested stream wrapper against the security policy, so a template such as `stream:php://filter/...` can no longer bypass `Security::$streams` (including `Security::$streams = null`) to read local files (CWE-22)

				- Fixed a `TypeError` on PHP 8 when `Security::$static_classes` was set to a non-array value (e.g. the string `'none'`) to disable static class access; any non-array value now cleanly denies access. Use `Security::$static_classes = null` to disable access to all static classes.
