Twig, the flexible, fast, and secure template language for Codeigniter 4
========================================================================

[](#twig-the-flexible-fast-and-secure-template-language-for-codeigniter-4)

Twig is a template language for PHP.

Twig uses a syntax similar to the Django and Jinja template languages which inspired the Twig runtime environment.

[![Build Status](https://github.com/daycry/twig/actions/workflows/phpunit.yml/badge.svg?branch=master)](https://github.com/daycry/twig/actions/workflows/phpunit.yml)[![Coverage Status](https://camo.githubusercontent.com/39fa376aecd062050bdb18f9eacd5626caca2e44b68e78d9dcdfa62f921418be/68747470733a2f2f636f766572616c6c732e696f2f7265706f732f6769746875622f6461796372792f747769672f62616467652e7376673f6272616e63683d6d6173746572)](https://coveralls.io/github/daycry/twig?branch=master)[![Downloads](https://camo.githubusercontent.com/649d712d4fc33ad4ca8885c52be0232d13c5b06714c48ec259c730e844505656/68747470733a2f2f706f7365722e707567782e6f72672f6461796372792f747769672f646f776e6c6f616473)](https://packagist.org/packages/daycry/twig)[![GitHub release (latest by date)](https://camo.githubusercontent.com/38113e0d8e3ddee2b4137763d1d6a35abf33174019ddf8e5b541afbff7e78c0c/68747470733a2f2f696d672e736869656c64732e696f2f6769746875622f762f72656c656173652f6461796372792f74776967)](https://packagist.org/packages/daycry/twig)[![GitHub stars](https://camo.githubusercontent.com/24c69ac78b7936c8a6a0c41ea257e83bc9b9094d6c931391a39309db891c69d0/68747470733a2f2f696d672e736869656c64732e696f2f6769746875622f73746172732f6461796372792f74776967)](https://packagist.org/packages/daycry/twig)[![GitHub license](https://camo.githubusercontent.com/35daa0af46375b744093d4b4dd2fe56c4337697f09508699e3d005a6591598c0/68747470733a2f2f696d672e736869656c64732e696f2f6769746875622f6c6963656e73652f6461796372792f74776967)](https://github.com/daycry/twig/blob/master/LICENSE)

v3.0.0 Highlights
-----------------

[](#v300-highlights)

Major architectural refactor (internal) with backward‑compatible public API:

- Extracted modular services:
    - TemplateDiscovery – template enumeration &amp; in-process caching
    - TemplateCacheManager – compile index (compile-index.json) &amp; compiled state tracking
    - DynamicRegistry – runtime registration of functions &amp; filters
    - TemplateInvalidator – single/batch/namespace cache invalidation
- New listing filters: namespace + glob/pattern (e.g. `@admin/*`, `emails/user_*`).
- Optimized batch invalidation (single directory scan for multiple templates).
- Warmup now persists &amp; reuses a compile index; skipping already compiled templates is faster.
- Structured logging normalized: `event=twig.* key=value` pairs (update log parsers if any).
- Namespace-specific autoescape strategy mapping (`setAutoescapeForNamespace`).
- `Twig` facade slimmed; internal arrays removed in favor of service classes.

Service Architecture Guide: See `docs/SERVICES.md` for an in-depth explanation of the new modular internal services (Discovery, CacheManager, DynamicRegistry, Invalidator) and advanced usage patterns.

Upgrade Notes:

- No breaking changes for typical usage (render/display/registerFunction/registerFilter/warmup/invalidate APIs preserved).
- If you accessed internal properties like `$compiledTemplates` directly, migrate to the public methods (`warmup`, `listTemplates`, `invalidate*`).
- Log format changed; adjust any monitoring tools expecting old message text.
- Version bumped to v3 to reflect the internal restructuring &amp; new operational capabilities rather than surface API breaks.

### Current Behavior

[](#current-behavior)

Discovery snapshot, preload and APCu acceleration are automatic in the default profile (`leanMode = false`). In Lean Mode they are disabled unless explicitly re-enabled with `enableDiscoverySnapshot`.

### v3.x Runtime Capability Model

[](#v3x-runtime-capability-model)

Runtime features are governed by a profile (Full vs Lean) plus nullable overrides:

CapabilityFull (leanMode = false)Lean (leanMode = true)Override `null`Override `true`Override `false`Discovery Snapshot (persist + preload + APCu)ONOFFInherit profileForce ONForce OFFWarmup Summary PersistenceONOFFInherit profileForce ONForce OFFInvalidation History (last + cumulative)ONOFFInherit profileForce ONForce OFFDynamic Metrics (function/filter counts)ONOFFInherit profileForce ONForce OFFExtended Diagnostics (names lists, static counts)ONOFFInherit profileForce ONForce OFF`null` significa “hereda el perfil base”. Establecer explícitamente `true` / `false` domina siempre al modo (Full / Lean).

### Automatic Cache Backend Detection

[](#automatic-cache-backend-detection)

El sistema siempre invoca `service('cache')`:

- Si el handler es FileHandler (clase contiene `File`) =&gt; modo `filesystem` usando la ruta `cachePath` (por defecto `WRITEPATH/cache/twig`).
- Cualquier otro handler =&gt; modo `service` (se envuelve en `CICacheAdapter` para compilados Twig e índices).

Diagnóstico (`getDiagnostics()['cache']`):

```
{
    "enabled": true,
    "path": "/var/www/app/writable/cache/twig",   // null cuando mode=service
    "mode": "filesystem" | "service",
    "service_class": "CodeIgniter\\Cache\\Handlers\\RedisHandler", // sólo en service
    "prefix": "twig_",    // derivado de Config\Cache::$prefix + 'twig_'
    "ttl": 0,              // 0 = sin expiración (habitual para compilados)
    "compiled_templates": 42,
    "reconstructed_index": false
}
```

#### Cache Key Prefix (Simplified)

[](#cache-key-prefix-simplified)

The prefix strategy was further simplified: we no longer embed the textual global cache prefix into Twig keys. Instead only two possibilities exist:

- Global `Config\Cache::$prefix` ends with `_` (non-empty) ⇒ prefix used: `_twig_`
- Otherwise ⇒ prefix used: `twig_`

The previous form `( + '_') . 'twig_'` was removed to avoid accidental duplication and shorten keys. The removed per-Twig `cachePrefix` override remains removed.

Examples:

- `''` → `twig_`
- `'app'` → `twig_`
- `'app_'` → `_twig_`
- `'mediaprous_'` → `_twig_`

Applies uniformly to compiled templates, compile index, discovery snapshot, warmup summary &amp; invalidation history.

Diagnostics expose the resolved value at `diagnostics['cache']['prefix']`.

### Persistence Medium Map (`diagnostics['persistence']`)

[](#persistence-medium-map-diagnosticspersistence)

Claves posibles: `compile_index`, `discovery_snapshot`, `warmup`, `invalidations`.

Valor: `{ "medium": "file" | "ci" }` donde `ci` representa uso de cache service (cualquier handler no-file). Ejemplo:

```
"persistence": {
    "compile_index": { "medium": "ci" },
    "discovery_snapshot": { "medium": "ci" },
    "warmup": { "medium": "ci" },
    "invalidations": { "medium": "ci" }
}
```

### Reconstructed Index

[](#reconstructed-index)

Si tras leer el índice (`compile-index.json` o clave remota) la lista está vacía pero se detectan ficheros PHP compilados (upgrade / copia manual), se crea un índice sintético con nombres `unknown_N`. Campo `reconstructed_index = true` advierte de esta situación; haz un warmup para regenerar un índice “real”.

### Lean vs Full Diagnostics Output

[](#lean-vs-full-diagnostics-output)

Lean elimina secciones completas (no aparecen las claves) para minimizar payload. Ejemplo (lean + sin overrides) sólo contiene: `renders`, `last_render_view`, `environment_resets`, `cache`, `performance`, `capabilities`, `persistence` (y discovery si forzado). Cualquier override `true` reintroduce su sección concreta.

### Debug Toolbar Tuning

[](#debug-toolbar-tuning)

Para instalaciones grandes o páginas con mucho JavaScript, el panel de Twig puede añadir latencia si renderiza todas las secciones (discovery, dynamics, templates) en cada request. Se proveen flags para reducir el trabajo de renderizado directamente (no existe ya modo diferido / fetch asincrónico; fue retirado por simplicidad y evitar recursiones de rutas).

Flags de configuración (en `Config\\Twig`):

FlagDefaultEfecto`toolbarMinimal`falseSi `true` sólo Core + Cache + Performance; omite Discovery, Warmup, Invalidations, Dynamics, Templates, Capabilities, Persistence.`toolbarShowTemplates`trueMuestra/oculta la tabla de plantillas. Ignorado si `toolbarMinimal=true`.`toolbarMaxTemplates`50Límite de filas en la tabla de plantillas.`toolbarShowCapabilities`trueMuestra sección de capabilities. Ignorado si minimal.`toolbarShowPersistence`trueMuestra mediums de persistencia. Ignorado si minimal.Ejemplo para máximo rendimiento en desarrollo (vista muy ligera):

```
$config->toolbarMinimal = true; // Sólo métricas esenciales
```

Perfil intermedio sin tabla de plantillas pero con capabilities y persistence:

```
$config->toolbarMinimal = false;
$config->toolbarShowTemplates = false;
```

Estrategia sugerida:

1. Empieza con `toolbarMinimal=true` si sólo depuras conteos y cache.
2. Añade secciones puntualmente: desactiva minimal y activa sólo lo que necesitas (`toolbarShowTemplates=false` para omitir la tabla, reduce `toolbarMaxTemplates`).
3. Usa Lean Mode para reducir también el tamaño de la estructura JSON interna si consumes diagnostics externamente.

Notas:

- Todas las secciones se renderizan inline; no hay peticiones secundarias.
- Sin dependencias de JavaScript para cargar contenido dinámico del panel.
- Las optimizaciones se centran en no construir HTML innecesario.

### Ejemplos Rápidos

[](#ejemplos-rápidos)

Forzar snapshot en Lean:

```
$config->leanMode = true;
$config->enableDiscoverySnapshot = true; // sólo snapshot; warmupSummary, invalidations, metrics siguen OFF
```

Listar plantillas con estado de compilación:

```
$twig->listTemplates(true); // [['name'=>'welcome','compiled'=>true], ...]
```

Warmup y ver resumen:

```
$twig->warmup(['welcome']);
print_r($twig->getDiagnostics()['warmup']);
```

Installation via composer
-------------------------

[](#installation-via-composer)

Use the package with composer install

```
> composer require daycry/twig

```

Configuration
-------------

[](#configuration)

Run command:

```
> php spark twig:publish

```

This command will copy a config file to your app namespace. Then you can adjust it to your needs. By default file will be present in `app/Config/Twig.php`.

### Configuration Quick Start

[](#configuration-quick-start)

```
$config = new \Daycry\Twig\Config\Twig();

// Optional: enable strict variables (throw on undefined)
$config->strictVariables = true;

// Optional: Lean Mode (disable non-essential persistence & diagnostics)
$config->leanMode = true;                      // minimal overhead
$config->enableDiscoverySnapshot = true;       // re-enable snapshot in lean if you have many templates

// Custom template paths (optionally with namespace)
$config->paths = [APPPATH.'Module/Views', [APPPATH.'Admin/Views','admin']];

// Create instance
$twig = new \Daycry\Twig\Twig($config);
```

Profiles Summary:

- Full (default): snapshot + preload + APCu (if available) + all diagnostics.
- Lean: minimal persistence; selectively re-add capabilities via nullable overrides.

Usage Loading Library
---------------------

[](#usage-loading-library)

```
$twig = new \Daycry\Twig\Twig();
$twig->display( 'file.html', [] );
```

Usage as a Service
------------------

[](#usage-as-a-service)

```
$twig = \Config\Services::twig();
$twig->display( 'file.html', [] );
```

Usage as a Helper
-----------------

[](#usage-as-a-helper)

In your BaseController - $helpers array, add an element with your helper filename.

```
protected $helpers = [ 'twig_helper' ];
```

And then you can use the helper

```
$twig = twig_instance();
$twig->display( 'file.html', [] );
```

Add Globals
-----------

[](#add-globals)

```
$twig = new \Daycry\Twig\Twig();

$session = \Config\Services::session();
$session->set( array( 'name' => 'Daycry' ) );
$twig->addGlobal( 'session', $session );
$twig->display( 'file.html', [] );
```

File Example
------------

[](#file-example)

```
DOCTYPE html>

        Example

        Hi {{ name }}
        {{ dump( session.get( 'name' ) ) }}

```

Collector
---------

[](#collector)

If you want to debug the data in twig templates.

Toolbar.php file

```
    use Daycry\Twig\Debug\Toolbar\Collectors\Twig;

    public array $collectors = [
        ...
        //Views::class,
        Twig::class
    ];
```

Advanced Features
-----------------

[](#advanced-features)

### Caching &amp; Persistence Overview

[](#caching--persistence-overview)

This integration implements a multi-layer caching architecture covering:

1. Compiled template classes (auto-detected backend: CI cache service if available, otherwise filesystem)
2. Compile index (logical template -&gt; compiled flag)
3. Template discovery stats + optional snapshot (with fingerprint &amp; APCu acceleration)
4. Warmup summary persistence
5. Invalidation state (last + cumulative)

Backend selection is automatic (CI cache service if available, otherwise filesystem). Prefix derives from global cache config; TTL normally unlimited.

Discovery snapshot, preload and APCu acceleration are now automatic in the full profile (leanMode = false). Use `enableDiscoverySnapshot` when in Lean Mode to opt back in.

Warm all templates once after deployment:

```
php spark twig:warmup --all

```

Clear everything (compiled + persisted artifacts):

```
php spark twig:clear-cache --reinit

```

See full details, key layout, and troubleshooting in `docs/CACHING.md`.

### Further Reading

[](#further-reading)

- `docs/SERVICES.md` – Modular internal services (Discovery, CacheManager, DynamicRegistry, Invalidator)
- `docs/PERFORMANCE.md` – Warmup strategy, discovery tuning, invalidation efficiency, diagnostics interpretation

### Lean Mode (Low-Overhead Profile)

[](#lean-mode-low-overhead-profile)

Enable Lean Mode to minimize persistence &amp; diagnostic overhead:

```
$config->leanMode = true; // disables warmup summary, invalidation history, discovery snapshot, dynamic & extended diagnostics
```

Re-enable selected capabilities while staying in Lean:

```
$config->leanMode = true;
$config->enableDiscoverySnapshot = true;   // keep snapshot for faster discovery
$config->enableWarmupSummary = true;       // record last warmup result
```

If `leanMode = false` (default) all capabilities are active automatically (snapshot always on now).

See `docs/CACHING.md` (section "Lean Mode &amp; Capability Overrides") and `docs/PERFORMANCE.md` for rationale &amp; cost matrix.

### Custom Loader Injection

[](#custom-loader-injection)

Replace the internal loader (e.g. use an in-memory `ArrayLoader` for tests):

```
use Twig\\Loader\\ArrayLoader;
use Daycry\\Twig\\Twig;

$twig = new Twig();
$twig->withLoader(new ArrayLoader([
    'hello.twig' => 'Hello {{ name }}'
]));

echo $twig->render('hello', ['name' => 'World']);
```

### Strict Variables

[](#strict-variables)

Enable strict mode (undefined variables throw a `RuntimeError`):

```
$config = new \\Daycry\\Twig\\Config\\Twig();
$config->strictVariables = true;
$twig = new Twig($config);
```

### Dynamic Registration (Functions &amp; Filters)

[](#dynamic-registration-functions--filters)

Register functions or filters at runtime, even before the first render. Items queued before initialization are applied automatically.

Supports:

1. Boolean shorthand (backward compatible) → safe HTML when true.
2. Array options mirroring native Twig options (`is_safe`, `needs_environment`, `needs_context`, etc.).

```
// Boolean shorthand
$twig->registerFunction('hello_fn', fn(string $n) => 'Hello ' . $n);             // escaped by default
$twig->registerFunction('raw_html', fn() => 'Bold', true);                // mark as safe HTML

// Array options (new)
$twig->registerFunction('upper_env',
    function(\Twig\Environment $env, string $v) { return strtoupper($v); },
    ['needs_environment' => true]
);

// Filters
$twig->registerFilter('exclaim', fn(string $v) => $v . '!', ['is_safe' => ['html']]);
$twig->registerFilter('italic', fn(string $v) => ''.$v.'', []);           // will be escaped
```

Usage in templates:

```
{{ hello_fn('World') }} {# Hello World #}
{{ raw_html() }}        {# Bold (not escaped) #}
{{ 'wow'|exclaim }}     {# wow! #}
{{ 'x'|italic }}        {# &lt;i&gt;x&lt;/i&gt; because unsafe #}
```

### Cache Management

[](#cache-management)

Specify a custom cache path via config:

```
$config = new \\Daycry\\Twig\\Config\\Twig();
$config->cachePath = WRITEPATH.'cache'.DIRECTORY_SEPARATOR.'twig_custom';
$twig = new Twig($config);
```

Clear compiled templates (optionally reinitializing the environment):

```
$removedFiles = $twig->clearCache();       // remove compiled files only
$removedFiles = $twig->clearCache(true);   // also reset Twig Environment
$cacheDir     = $twig->getCachePath();
```

### Example: Combining Everything

[](#example-combining-everything)

```
$config = new \\Daycry\\Twig\\Config\\Twig();
$config->strictVariables = true;
$config->cachePath = WRITEPATH.'cache/twig_app';

$twig = new Twig($config);

$twig->registerFunction('link', fn(string $t, string $u) => ''.esc($t).'', true);
$twig->registerFilter('reverse', fn(string $v) => strrev($v));

echo $twig->render('page', ['title' => 'My Page']);
```

If you change templates programmatically and need a fresh compile, call `clearCache(true)`.

### Dynamic Extension Registration

[](#dynamic-extension-registration)

You can add Twig extensions at runtime:

```
use Daycry\Twig\Twig;
use App\Twig\MyExtension; // extends \Twig\Extension\AbstractExtension

$twig = new Twig();
$twig->registerExtension(MyExtension::class); // queued or immediate
```

### CLI: Clear Twig Cache

[](#cli-clear-twig-cache)

After installing, you can clear compiled templates from the CLI:

```
php spark twig:clear-cache
php spark twig:clear-cache --reinit   # also recreates the Environment

```

### Selective Template Invalidation

[](#selective-template-invalidation)

Remove cache for a single logical template name (without extension):

```
$twig->invalidateTemplate('emails/welcome');           // best-effort removal
$twig->invalidateTemplate('emails/welcome', true);     // remove + reinitialize environment
```

CLI variant:

```
php spark twig:invalidate emails/welcome
php spark twig:invalidate emails/welcome --reinit

```

### Batch &amp; Namespace Invalidation

[](#batch--namespace-invalidation)

Invalidate multiple logical template names in one call:

```
$summary = $twig->invalidateTemplates(['welcome','emails/welcome','admin/dashboard']);
/* $summary example:
[
    'removed'   => 3,        // total cache files removed
    'templates' => [         // per logical template details
        'welcome' => 1,
        'emails/welcome' => 1,
        'admin/dashboard' => 1,
    ],
    'reinit' => false,
]*/

// Force environment recreation after invalidation:
$twig->invalidateTemplates(['welcome'], true);
```

Invalidate by namespace (when using namespaced paths `@namespace`):

```
// Invalidate all templates under namespace '@admin'
$twig->invalidateNamespace('@admin');

// Invalidate all templates in the main (root) namespace
$twig->invalidateNamespace(null);
```

### Warmup / Precompilation

[](#warmup--precompilation)

Precompile templates to avoid first-hit latency. Two APIs:

```
// Specific templates (logical names without extension)
$summary = $twig->warmup(['welcome','emails/welcome']);
// All discovered templates under configured paths
$summaryAll = $twig->warmupAll();

/* Returned structure:
[
    'compiled' => 5,
    'skipped'  => 12, // already compiled
    'errors'   => 0,
]
*/

// Force recompilation ignoring existing compiled cache fingerprints
$twig->warmup(['welcome'], true);
```

CLI command:

```
php spark twig:warmup --all
php spark twig:warmup welcome emails/welcome
php spark twig:warmup welcome --force   # recompile even if cached

```

Warmup uses a heuristic hash check (md5 of logical name) to decide if a template seems compiled; `--force` bypasses this.

### Logging

[](#logging)

All logging now delegates entirely to CodeIgniter's native `log_message()` helper. No internal logger instance or `setLogger()` method exists anymore.

Log entries follow a normalized `event= key=value ...` pattern for easier machine parsing. Representative events (levels vary: debug/info/error):

- `twig.functions.start`, `twig.functions.ready`
- `twig.function.queued`, `twig.function.registered`, `twig.function.unregistered`
- `twig.filter.queued`, `twig.filter.registered`, `twig.filter.unregistered`
- `twig.extension.queued`, `twig.extension.registered`, `twig.extension.queued_recreate`, `twig.extension.unregistered`
- `twig.cache.enabled`, `twig.cache.disabled`, `twig.cache.cleared`
- `twig.template.invalidated`, `twig.templates.invalidated`, `twig.namespace.invalidated`
- `twig.warmup.compiled`, `twig.warmup.error`
- `twig.loader.replaced`, `twig.reset`

Control verbosity via your global `app/Config/Logger.php`. No additional configuration is required inside `Twig`.

Breaking change: previous ad-hoc message formats were replaced; if you had log parsers, update them to consume the new key=value style.

### CLI Commands Overview

[](#cli-commands-overview)

CommandDescriptionCommon Options / Notes`php spark twig:publish`Publish the config file to `app/Config/Twig.php`.Run once after install.`php spark twig:clear-cache`Delete compiled cache files.`--reinit` recreate environment after clearing.`php spark twig:invalidate `Invalidate a single logical template.`--reinit` if removed. Name without extension.`php spark twig:invalidate:batch   ...`Invalidate multiple logical templates.`--reinit` if any removed.`php spark twig:warmup`Precompile specific templates.Provide names or use `--all`; `--force` to ignore existing cache.`php spark twig:list`List discovered logical templates.`--status` to include compiled flag.`php spark twig:stats`Show counts &amp; cache information.Reads compile index and cache directory.### Template Listing &amp; Filtering

[](#template-listing--filtering)

Use the `listTemplates()` API to enumerate logical names. You can filter by namespace and/or a glob-style pattern (`*` and `?`).

```
// All templates
$all = $twig->listTemplates();

// All templates inside a namespace
$admin = $twig->listTemplates(false, '@admin');

// Pattern filtering (within namespace)
$adminDash = $twig->listTemplates(false, '@admin', 'dash*/index');

// With compiled status
$withStatus = $twig->listTemplates(true);
```

Patterns are case-insensitive. If a namespace is supplied, the pattern is matched against the path portion inside that namespace.

### Template Discovery Cache

[](#template-discovery-cache)

Discovered logical template names are cached per-process (context hash: loader class + paths + extension). The cache invalidates automatically when:

1. Loader is replaced (`withLoader()`)
2. Environment reset (`resetTwig()`) This reduces filesystem traversal on repeated listing or namespace invalidation operations.

Changelog (recent additions)
----------------------------

[](#changelog-recent-additions)

- Cache utilities: `getCachePath()`, `clearCache()`, runtime toggles `disableCache()`, `enableCache()`, `isCacheEnabled()`
- Selective, batch, and namespace invalidation: `invalidateTemplate()`, `invalidateTemplates()`, `invalidateNamespace()` + CLI counterparts
- Warmup &amp; precompilation: `warmup()`, `warmupAll()` with persisted compile index (`compile-index.json`)
- Listing &amp; status: `listTemplates()` (with namespace/pattern filtering &amp; compiled status)
- Namespace auto-escape strategy mapping: `setAutoescapeForNamespace()`, `removeAutoescapeForNamespace()`

Roadmap / Ideas
---------------

[](#roadmap--ideas)

Potential future exploration:

- Template dependency graph (track includes/extends for smarter invalidation)
- Optional metrics hook (expose render times to an external profiler)
- Pluggable cache backend abstraction (filesystem vs memory)
- Enhanced auto-escape strategies (contextual by file pattern)
- Interactive CLI (prompt-driven) for template operations

### New Features Documentation

[](#new-features-documentation)

#### Unregister Runtime Additions

[](#unregister-runtime-additions)

Remove previously registered dynamic artifacts:

```
$twig->unregisterFunction('temp_fn');
$twig->unregisterFilter('brackets');
$twig->unregisterExtension(MyExtension::class);
```

#### Runtime Cache Toggle

[](#runtime-cache-toggle)

Disable recompilation writing and force non-cached rendering (development convenience):

```
$twig->disableCache();          // turns off cache (does not delete existing by default)
$twig->disableCache(true);      // also removes existing compiled files
$twig->enableCache();           // re-enable with default path
$twig->enableCache('/custom/path');
if (!$twig->isCacheEnabled()) { /* ... */ }
```

#### Namespace Auto-Escape Mapping

[](#namespace-auto-escape-mapping)

Set different escaping strategies per Twig namespace (leading `@` omitted when specifying):

```
$twig->setAutoescapeForNamespace('admin', 'html');
$twig->setAutoescapeForNamespace('rawmail', false);   // disable escaping
$twig->removeAutoescapeForNamespace('rawmail');
```

#### Persistent Compile Index &amp; Listing

[](#persistent-compile-index--listing)

Warmup operations store compiled logical names into `compile-index.json` within the cache directory.

```
$twig->warmup(['welcome']);
$templates = $twig->listTemplates(true); // [['name' => 'welcome', 'compiled' => true], ...]
```

#### New CLI Commands

[](#new-cli-commands)

```
php spark twig:list             # list logical template names
php spark twig:list --status    # include compiled status (from index)
php spark twig:stats            # show counts & cache info
php spark twig:invalidate:batch welcome emails/welcome

```
