Core concepts - -- Template: Text file (typically HTML) with Eyrie syntax. -- Context: Associative array passed at render time. -- Page: A top‑level template representing a view. Pages may extend a Layout and fill named Blocks. -- Layout: A template that defines the overarching structure (shell) and exposes named Blocks with optional defaults. -- Block: A named content region. Pages/components can override block content; `[[ super ]]` can include parent content. - - Component: A reusable, tag‑like unit rendered with a custom element syntax (e.g., `<@ Movie id="1" />`). Components encapsulate their own rendering and accept props. -- Props: Data passed to components (and optionally pages) akin to attributes; values flow from the rendering context and are subject to escaping. -- Helper: Whitelisted callable exposed to templates. -- Filter: Unary transformation applied via `|` pipe. -- Tag: Control structure/directive (loops, conditionals, includes, etc.). -- Loader: Resolves template names to sources. -- Cache: Compiled/intermediate representation for speed. - -## 5. Syntax overview - -- Output: `<< expression >>` prints value with auto‑escaping. -- Calls/control: control blocks start with `<(` and end with `)>`; examples use `<( if ... )>` / `<( endif )>`. -- Blocks/extends: `[[ ... ]]` for inheritance, blocks, includes. -- Components: `<@ ComponentName prop1="value" prop2={ expr } />` self‑closing. Support for children/content projection is TBD. - -### 5.1 Expressions - -- Property/array access: `user.name`, `order.items[0]`. -- Literals: strings, numbers, booleans, null. -- Operators: arithmetic, comparison, logical, ternary. -- Filters: `value | lower | escape('attr') | ...`. - -### 5.2 Output examples - -- Basic: `<< user.name >>` -- With filters: `<< title | upper >>` -- Raw (discouraged): `<< user.bio | raw >>` - -### 5.3 Control structures (inside `<( ... )>`) - -- If/elseif/else/end: - - `<( if cond )>` ... `<( elseif other )>` ... `<( else )>` ... `<( endif )>` -- Foreach: - - `<( foreach item in items )>` ... `<( endforeach )>` - - Loop vars (read‑only): `item` -- Loop (range/repeat): - - `<( loop from 0 to 10 )>` ... `<( endloop )>` - - Loop vars (read‑only): `loop.index` (int), `loop.first` (bool), `loop.last` (bool), `loop.length` (int) - -### 5.4 Inheritance and blocks (inside `[[ ... ]]`) - -- Extends: `[[ extends "layouts.base" ]]` (dot-notated paths, final part is parent file) - - Extends syntax does not include the layout file extension. - - Extends must be the first line of a template file. -- Declare/override: - - `[[ block content ]] ... [[ endblock ]]` - - `[[ super ]]` inside override to include parent content -- Block context (optional): `[[ block sidebar with { user: user } ]]` - -### 5.5 Partials -- Basic Include: `[[ include "partials.footer" ]]` -- Include with optional context: `[[ include "partials.footer" with { x: 1 } ]]` (dot-notated paths, final part is partial file) - - Include syntax does not include the partial file extension. - -### 5.6 Components - -- Tag‑based components are referenced by PascalCase names and invoked with the `<@` prefix: `<@ Movie id="1" />`. -- Props: - - String literal: `<@ Movie title="Jaws" />` - - Expression: `<@ Movie rating={ movie.rating } />` - - Boolean shorthand: `<@ Movie featured />` → `featured=true` -- Registration: components are registered in PHP (see API). Unregistered component names are a `SyntaxError` (configurable to `RuntimeError`). -- Auto‑escaping: Component outputs are escaped by context unless a component deliberately returns a `SafeHtml`‑like value. -- Context: Components receive props plus a limited view of the parent context (configurable); they do not mutate outer context. - - Layout/block interaction: Components can be used within Layouts and Pages but do not extend layouts themselves, and they do not define or fill block areas. - -### 5.7 Built‑in tags - -- `if/elseif/else/endif`, `foreach/endforeach`, `loop/endloop`, `include`, `extends`, `block/endblock`, `super` - -### 5.8 Helpers and filters - -- Helpers are registered by name in PHP and callable in `<( ... )>` or `<< >>`, e.g. `<< route('home') >>`. -- Filters chain with pipes, e.g. `<< text | truncate(120) | escape('attr') >>`. - -## 6. Auto‑escaping - -- Enabled by default for all `<< >>` outputs. -- Modes: `html` (default), `attr`, `url`, `js`. -- `escape(mode)` switches mode; `safe` marks trusted values to bypass escaping. -- Escaping happens after filters unless `safe` present. -- Component rendering occurs under the current escaping mode of the insertion site. - -## 7.

Errors and diagnostics +### 1. File Handling & Configuration +- **Template Extensions**: + - All templates, layouts, and partials must use the `.scape.php` extension. +- **Filter Extensions**: + - Custom filters must use the standard `.php` extension. + - All custom filters must implement the `Scape\Interfaces\FilterInterface` to ensure they provide the necessary transformation methods. +- **Directory Configuration**: Template locations are managed via environment variables: + - `SCAPE_TEMPLATES_DIR`: Main directory for application templates. + - `SCAPE_LAYOUTS_DIR`: Directory for base layouts and parent templates. + - `SCAPE_PARTIALS_DIR`: Directory for reusable snippets/partials. + - `SCAPE_FILTERS_DIR`: Directory for user-defined filters. +- **Dot Notation Pathing**: All internal paths (extends, includes) use dot notation (e.g., `sidebar.login_form`) relative to their respective directories, omitting the file extension. -- Exceptions: `TemplateError`, `SyntaxError`, `RuntimeError`, `LoaderError`. -- Messages include template name, line/col, and a snippet when possible. -- Configurable verbosity for dev vs prod. -- Useful diagnostics for components: unknown component name, invalid/unknown props, and type errors include the component tag snippet. +### 2. Syntax & White-space +- All opening and closing tags are white-space independent (e.g., `{{var}}` is equivalent to `{{ var }}`). +- **Variable Interpolation**: + - `{{ var }}`: Automatically HTML-escaped output (uses `ENT_QUOTES | ENT_SUBSTITUTE | ENT_HTML5`). + - `{{{ var }}}`: Raw, unescaped output. + - **Data Access**: + - Use dot-notation for accessing class properties/attributes (e.g., `user.name`). + - Use bracket notation for accessing array elements (e.g., `items['title']` or `users[0]`). -## 11. Performance targets (initial) +### 3. Logic & Control Flow +- **Syntax**: Uses `{( ... )}` for logic tags. +- **White-space Management**: Logic tags `{( ... )}` automatically consume one trailing newline immediately following the closing `)}` tag to prevent unintended vertical spacing in the rendered output. +- **"Logic-Light" Constraints**: + - No generic programming or complex expressions. + - No `if` statements or conditional branching (by design). + - No manual variable assignment within templates. +- **Loops**: + - Only bounded iteration is supported: `foreach`. + - **Grammar**: + - `{( foreach item in collection )} ... {( endforeach )}` + - `{( foreach key, item in collection )} ... {( endforeach )}` + - Every loop provides access to two local integer variables: + - `index`: The current iteration index, 0-indexed (0, 1, 2...). + - `pos`: The current human-readable position, 1-indexed (1, 2, 3...). + - **Positional Rendering**: Special tags are available within loops to handle presentation based on position: + - `{( first )} ... {( endfirst )}`: Renders only on the first iteration. + - `{( inner )} ... {( endinner )}`: Renders on all iterations except the first and last. + - `{( last )} ... {( endlast )}`: Renders only on the last iteration. -- Cold render p95 < 10ms for a ~5KB template on typical server hardware. -- Warm render p95 < 2ms with cache. -- Watchdog timeouts to limit parse/render and mitigate DoS. - - Component recursion and nesting limits (e.g., max depth) to prevent pathological trees. +### 4. Inheritance & Reusability +- **Syntax**: Uses `{[ ... ]}` for block and inheritance tags. +- **Layouts & Inheritance**: + - Templates can extend layouts from `SCAPE_LAYOUTS_DIR` using `{[ extends 'path' ]}`. + - The `extends` tag must be the very first thing in a template. +- **Blocks**: + - **Placeholder**: Layouts define placeholders using `{[ block 'name' ]} ... {[ endblock ]}`. + - **Override**: Child templates provide content for these placeholders by defining a block with the same name. + - **Parent Content**: Within an override block, the child can render the layout's default content using the `{[ parent ]}` tag. + - **Default Content**: If a child template does not provide a block, the content within the layout's `block` tags is rendered as a default. + - **Nested Blocks**: Blocks can be nested within other blocks. +- **Partials**: + - Reusable snippets from `SCAPE_PARTIALS_DIR` can be included using `{[ include 'path' ]}`. + - **Encapsulation**: Partials are siloed by default and do not inherit the parent template's variables. + - **Passing Data**: + - Data can be passed as an array: `{[ include 'path' with data_source ]}`. + - The `data_source` can be a local variable, a nested array element (`items['meta']`), a class attribute (`user.profile`), or an inline array declaration (e.g., `['user' => user, 'id' => 1]`). + - The array keys from the source are expanded into individual local variables within the partial. + - The full parent context can be passed explicitly: `{[ include 'path' with context ]}`. + - **Nesting**: Partials can include other partials. To prevent infinite recursion, the engine enforces a maximum nesting depth (default: 20). -## 12. Security requirements (summary) +### 5. Extensibility +- **Filters**: + - Used with variable interpolation to transform data. + - **Piping**: Supports chaining multiple filters: `{{ var | lower | ucfirst }}`. + - **Arguments**: Supports passing simple arguments (strings, numbers, or other variables): `{{ price | currency('USD') }}`. + - **The `FilterInterface`**: All filters must implement `Scape\Interfaces\FilterInterface`: + ```php + public function transform(mixed $value, array $args = []): mixed; + ``` + - **Loading**: Filters must be pre-loaded at the top of the template. + - **Internal Libraries**: Engine-provided filters are loaded using the `uses` keyword: + - Syntax: `{( uses namespace:library )}` (e.g., `{( uses filters:string )}`). + - **Custom Filters**: User-defined filters are loaded from `SCAPE_FILTERS_DIR` using `load_filter`. + - Syntax: `{( load_filter('path') )}` where path is dot-notated. -- Auto‑escape by default; `safe` is explicit opt‑in. -- No arbitrary PHP execution; only whitelisted helpers/filters. -- Loader prevents traversal; only configured roots. -- Sandboxed evaluation; no eval/reflection. -- Depth/iteration limits; template size/token limits. -- Restrictive cache dir permissions; validated paths. -- Components are pure render units: no filesystem/network access; no mutation of outer context; bounded recursion/depth. +### 6. Security & Error Handling +- **Contextual Escaping**: Standard `{{ }}` interpolation ensures XSS protection. +- **Missing Assets**: If a layout or partial is missing, the engine looks for a user-provided `404.scape.php` in `SCAPE_TEMPLATES_DIR`. If not found, it renders a built-in "Template 404" placeholder. +- **Exceptions**: The engine throws specific exceptions within the `Scape\Exceptions` namespace: + - `TemplateNotFoundException`: Main template, layout, or partial missing. + - `SyntaxException`: Malformed tags or disallowed logic (e.g. `if`). + - `FilterNotFoundException`: Target of `uses` or `load_filter` missing. + - `PropertyNotFoundException`: (Debug only) Accessing undefined key/property. + - `RecursionLimitException`: Partials exceed nesting limit (default 20). +- **Variable Access**: + - **Debug Mode**: Accessing a non-existent object property or array key throws a `PropertyNotFoundException`. + - **Production Mode**: Accessing a non-existent property or key fails silently and renders an empty string. -## 13. Logging and telemetry +### 7. Performance +- **AST Caching**: The engine caches the parsed Abstract Syntax Tree (AST) of templates to speed up subsequent renders. +- **Cache Location**: Cache files are stored locally in the project directory under `.scape/cache`. +- **No Compiling**: Scape does not compile templates into raw PHP files; it interprets the cached AST directly. +- **Cache Modes**: + - **Development**: Engine checks file modification times (`mtime`) to invalidate the cache when a template changes. + - **Production**: Engine skips `mtime` checks and serves the cached AST directly for maximum performance. -- Hook for timings, cache metrics, loader misses. -- PSR‑3 logger support. +### 8. Host Integration (IoC) +- **The `host` Namespace**: Scape provides a reserved `host` namespace that can be used with the `uses` keyword or as a filter/function prefix. +- **Provider Registration**: Host frameworks (e.g., Phred) can register custom providers to handle calls in this namespace. +- **Use Cases**: Used for framework-level features like feature flags (Flagpole), routing, or translations without creating a hard dependency within the engine. +- **Default Behavior**: If no provider is registered, calls to the `host` namespace return the input value unchanged or `null`. -## 14. Compatibility +### 9. Runtime API +- **The `Scape\Engine` Class**: The primary entry point for the library. +- **Configuration Precedence**: Programmatic Config > Environment Variables > Defaults. +- **Rendering**: + - Method: `public function render(string $template, array $data = []): string` + - The `$template` argument uses dot notation. +- **Mode Control**: The engine operating mode (`debug` vs `production`) can be set via the `SCAPE_MODE` environment variable or explicitly during instantiation. -- Minimum PHP: propose 8.1+ (finalize). -- UTF‑8 for sources and output. - -## 15.
