/** |
| 3 |
* Window notices — declarative top-of-window banners. |
| 4 |
* |
| 5 |
* Plugins call `openstation_register_window_notice()` to surface a |
| 6 |
* tone-coded banner at the top of every window matching a `match` |
| 7 |
* predicate (or every window by default). The shell renders the |
| 8 |
* notice via the `<os-notice>` web component inside the window's |
| 9 |
* `after-titlebar` slot, and records the user's dismissal in |
| 10 |
* `localStorage` so the same notice never reappears. |
| 11 |
* |
| 12 |
* Notices are pure declarative data — no JS handle is needed. |
| 13 |
* |
| 14 |
* Example: |
| 15 |
* |
| 16 |
* ```php |
| 17 |
* openstation_register_window_notice( array( |
| 18 |
* 'id' => 'my-plugin/welcome', |
| 19 |
* 'tone' => 'info', |
| 20 |
* 'message' => '<strong>Welcome!</strong> Read the <a href="…">docs</a>.', |
| 21 |
* 'match' => array( 'window' => 'edit-php' ), // optional |
| 22 |
* ) ); |
| 23 |
* ``` |
| 24 |
* |

| 41 |
* Register (or replace) a declarative window notice. |
| 42 |
* |
| 43 |
* @param array $args { |
| 44 |
* @type string $id Required. Persistence + dedupe key. |
| 45 |
* Recommended format `<plugin>/<slug>`. |
| 46 |
* @type string $message Required. HTML body. Passed through |
| 47 |
* `wp_kses_post()` before shipping, so |
| 48 |
* links + basic formatting are allowed |
| 49 |
* but `<script>` and other unsafe |
| 50 |
* markup are stripped. |
| 51 |
* @type string $tone Optional. One of |
| 52 |
* {@see openstation_window_notice_tones()}. |
| 53 |
* Default `info`. |
| 54 |
* @type bool $dismissible Optional. Show a close button. |
| 55 |
* Default `true`. |
| 56 |
* @type string $icon Optional. Dashicons class for a |
| 57 |
* leading glyph (e.g. |
| 58 |
* `dashicons-info`). Must match |
| 59 |
* `/^dashicons-[a-z0-9-]+$/`; values |
| 60 |
* that don't are silently dropped to |
| 61 |
* `''` rather than failing the |
| 62 |
* registration. |
| 63 |
* @type array $match Optional. Per-window selector. Pick |
| 64 |
* any of: |
| 65 |
* - `'window' => 'edit-php'` — single |
| 66 |
* window id (e.g. `edit-php` for |
| 67 |
* Posts, `plugins` for the native |
| 68 |
* Plugins window). |
| 69 |
* - `'windows' => array( 'edit-php', |
| 70 |
* 'edit-php-pagename' )` — multiple |
| 71 |
* window ids ("all windows of kind |
| 72 |
* X / Y / Z"). Within the array the |
| 73 |
* semantics is OR (any id matches). |
| 74 |
* - `'urlContains' => 'wc-admin'` — |
| 75 |
* case-insensitive URL substring |
| 76 |
* match. Useful for plugin pages |
| 77 |
* whose id is derived from a long |
| 78 |
* URL. |
| 79 |
* |
| 80 |
* When more than one selector type is |
| 81 |
* present, all of them must match |
| 82 |
* (AND). E.g. `array( 'windows' => |
| 83 |
* array( 'edit-php' ), 'urlContains' |
| 84 |
* => 'wc-admin' )` shows the notice |
| 85 |
* only on the Posts window when its |
| 86 |
* URL also contains `wc-admin` — not |
| 87 |
* on every Posts window AND every |
| 88 |
* wc-admin-URL window. Use two |
| 89 |
* separate `openstation_register_window_notice()` |
| 90 |
* calls for OR-across-selector-types. |
| 91 |
* |
| 92 |
* When omitted, the notice paints on |
| 93 |
* every window. |
| 94 |
* @type int $order Optional. Sort order — lower |
| 95 |
* renders higher in a stack of |
| 96 |
* notices. Default 100. |
| 97 |
* } |
| 98 |
* @return true|WP_Error `true` on success; `WP_Error` on validation |
| 99 |
* failure. |
