/** |
| 3 |
* OpenStation — PHP helpers for plugin authors. |
| 4 |
* |
| 5 |
* Two companion helpers live here: |
| 6 |
* |
| 7 |
* - {@see openstation_component()} prints a `<os-*>` tag with |
| 8 |
* safely-escaped attributes (plus its style-array |
| 9 |
* serializers). The intent is explicit (we're rendering a kit |
| 10 |
* component, not arbitrary HTML) and the escape discipline is |
| 11 |
* automatic. |
| 12 |
* |
| 13 |
* - {@see openstation_enqueue_script()} wraps |
| 14 |
* `wp_enqueue_script()` with the `openstation` + `wp-hooks` |
| 15 |
* dependencies pre-wired, so shell-extending scripts always |
| 16 |
* load after `wp.os.*` and `wp.hooks` are available. |
| 17 |
* |
| 18 |
* {@see openstation_register_window()} moved to |
| 19 |
* `includes/registries/native-windows.php`. |
| 20 |
* |
| 21 |
* @package OpenStation |
| 22 |

/** |
| 27 |
* Output a `<os-*>` component with safely escaped attributes. |
| 28 |
* |
| 29 |
* ```php |
| 30 |
* openstation_component( 'os-button', array( |
| 31 |
* 'variant' => 'primary', |
| 32 |
* 'data-op' => 'add', |
| 33 |
* 'aria-label' => __( 'Add', 'my-plugin' ), |
| 34 |
* ), '+' ); |
| 35 |
* ``` |
| 36 |
* |
| 37 |
* Attribute values flow through `esc_attr()` — no HTML injection |
| 38 |
* surface. Content is passed through verbatim; callers that want |
| 39 |
* to render user text should pre-escape with `esc_html()` / |
| 40 |
* `wp_kses()` themselves. |
| 41 |
* |
| 42 |
* Boolean-style attributes (present with a `true` value or an |
| 43 |
* empty string) render as bare attributes (`disabled`, |
| 44 |
* `fill-cell`) — matches the HTML5 boolean-attribute convention |
| 45 |
* every `<os-*>` follows. |
| 46 |
* |
| 47 |
* ## Inline styles |
| 48 |
* |
| 49 |
* The `style` key accepts either the usual string value or an |
| 50 |
* associative array of CSS-property → value pairs. The array form |
| 51 |
* auto-serializes to a CSS declaration list and auto-units bare |
| 52 |
* integers on length-shaped properties (padding, margin, width, |
| 53 |
* …) so `'padding' => 0` produces `padding: 0` and |
| 54 |
* `'padding' => 16` produces `padding: 16px`. |
| 55 |
* |
| 56 |
* ```php |
| 57 |
* openstation_component( 'os-stack', array( |
| 58 |
* 'gap' => 12, |
| 59 |
* 'style' => array( |
| 60 |
* 'padding' => 0, |
| 61 |
* 'background' => 'rgba(0,0,0,0.04)', |
| 62 |
* 'border-radius' => 8, |
| 63 |
* ), |
| 64 |
* ), $children ); |
| 65 |
* // <os-stack gap="12" style="padding: 0; background: rgba(0,0,0,0.04); border-radius: 8px"> |
| 66 |
* ``` |
| 67 |
* |
| 68 |
* Plain string form (for one-line overrides) keeps working: |
| 69 |
* |
| 70 |
* ```php |
| 71 |
* openstation_component( 'os-stack', array( |
| 72 |
* 'style' => 'padding: 0; margin-top: 16px', |
| 73 |
* ), $children ); |
| 74 |
* ``` |
| 75 |
* |
| 76 |
* @param string $tag Tag name, e.g. `os-button`. |
| 77 |
* Whitelisted to the `os-*` prefix |
| 78 |
* to prevent the helper being |
| 79 |
* misused as a generic HTML emitter. |
| 80 |
* @param array<string,mixed> $attrs Attribute key/value pairs. |
| 81 |
* `style` may be a string or an |
| 82 |
* associative array (see above). |
| 83 |
* @param string $content Inner HTML. Pass pre-escaped. |
