| 8 |
* - `openstation_native_window_registry()` — internal store |
| 9 |
* - `openstation_native_window_allowed_html()` — wp_kses |
| 10 |
* allowlist for `<template>` payloads |
| 11 |
* - `openstation_build_native_window_template_html()` — |
| 12 |
* wraps the registered template callback in tabs markup |
| 13 |
* when the window has multiple registered tabs |
| 14 |
* - `openstation_enqueue_native_window_scripts()` — enqueue |
| 15 |
* hook that ships every registered window's script handle |
| 16 |
* - `openstation_render_native_window_templates()` — renders |
| 17 |
* the `<template>` elements the shell clones |
| 18 |
* |
| 19 |
* Extracted from `components.php` during the architecture-0.8.1 |
| 20 |

/** |
| 29 |
* Register a PHP-owned native desktop window with one call. |
| 30 |
* |
| 31 |
* Under the hood this: |
| 32 |
* |
| 33 |
* 1. Captures the $args and stores them on a module-level |
| 34 |
* registry so the relevant admin_footer + enqueue hooks fire |
| 35 |
* only for the current user's openstation shell. |
| 36 |
* 2. On `admin_footer` (shell-side only), emits |
| 37 |
* `<template id="os-native-window-<id>">` wrapping the |
| 38 |
* output of the `template` callback. Each registered window |
| 39 |
* gets its own template element. |
| 40 |
* 3. On `admin_enqueue_scripts` (shell-side), enqueues the |
| 41 |
* caller's `script` handle if one was provided. The script |
| 42 |
* registers a render callback at |
| 43 |
* `window.openStationNativeWindows[<id>]`. On every window open |
| 44 |
* the shell clones the registered template into the body and |
| 45 |
* then invokes the callback — render is enhancement: query |
| 46 |
* the body for mount points your template declared, light |
| 47 |
* them up. Without a `script` the cloned template IS the |
| 48 |
* window; declarative-only plugins need zero JS. |
| 49 |
* 4. Passes a localized config blob to the script |
| 50 |
* (`openStationNativeWindow_<id>`) carrying the window's |
| 51 |
* `id`, `title`, `icon`, dimensions, and `placement`. The |
| 52 |
* script then calls `wp.os.registerSystemTile()` + |
| 53 |
* `wp.os.registerWindow()` to wire up the dock tile |
| 54 |
* and the open-on-click behaviour. |
| 55 |
* |
| 56 |
* Plugins write the template callback + the render callback on |
| 57 |
* the JS side; everything else is shell plumbing. Capability gate |
| 58 |
* honours WP admin conventions: any `capabilities` entries must |
| 59 |
* ALL match for the window to register. |
| 60 |
* |
| 61 |
* Note on scope: the shell doesn't auto-open windows server-side |
| 62 |
* — `registerWindow` declares availability, not presence. Users |
| 63 |
* click the registered tile (or your plugin calls |
| 64 |
* `wp.os.windowManager.open()` programmatically) to surface |
| 65 |
* the window. |
| 66 |
* |
| 67 |
* @param string $id Doubles as window id + dock-tile id. Must |
| 68 |
* be a kebab-case-ish slug. |
| 69 |
* @param array $args { |
| 70 |
* Window registration options. |
| 71 |
* |
| 72 |
* @type string $title Window + tooltip title. Required. |
| 73 |
* @type string $icon Dashicons class or URL. Required. |
| 74 |
* @type callable $template Echoes the window body markup. |
| 75 |
* Wrapped on `admin_footer` in a |
| 76 |
* `<template id="os-native-window- |
| 77 |
* <id>">`; cloned into the window |
| 78 |
* body on every open. The render |
| 79 |
* callback runs against the cloned |
| 80 |
* body, so mount points declared in |
| 81 |
* the template are guaranteed to be |
| 82 |
* present. |
| 83 |
* @type string $script Registered script handle that |
| 84 |
* owns the JS render callback. |
| 85 |
* Optional — omit for a purely |
| 86 |
* declarative window whose body is |
| 87 |
* exactly the cloned template. |
| 88 |
* Loaded the first time the window |
| 89 |
* opens, not at boot — see |
| 90 |
* `$preload_script`. |
| 91 |
* @type string[] $scripts Companion script handles loaded |
| 92 |
* immediately before `$script`, in |
| 93 |
* the order given. For a bundle that |
| 94 |
* extends the window from outside it |
| 95 |
* — subscribing to the window's own |
| 96 |
* actions, contributing a section — |
| 97 |
* and therefore has to be in the tab |
| 98 |
* before the window's render callback |
| 99 |
* paints. Declaring it here is what |
| 100 |
* keeps it off the boot critical |
| 101 |
* path: it travels with the window |
| 102 |
* it extends. Default empty. |
| 103 |
* @type string[] $styles Companion style handles injected on |
| 104 |
* the window's first open, after the |
| 105 |
* window's own `$style`, in the order |
| 106 |
* given — so at equal specificity a |
| 107 |
* companion's overrides win, the same |
| 108 |
* source-order contract an enqueue |
| 109 |
* dependency gives. The styles-side |
| 110 |
* mirror of `$scripts`: a stylesheet |
| 111 |
* that only paints surfaces inside |
| 112 |
* this window is dead weight on every |
| 113 |
* document that never shows it — |
| 114 |
* declared here it costs nothing at |
| 115 |
* boot and never reaches chromeless |
| 116 |
* iframes at all. Unlike `$style` |
| 117 |
* (injected when the window registers, |
| 118 |
* so mid-session activations paint), |
| 119 |
* companions wait for the first open; |
| 120 |
* the deferral is the point. Default |
| 121 |
* empty. |
| 122 |
* @type bool $preload_script Load `$script` (and `$scripts`) at |
| 123 |
* shell boot instead of on first |
| 124 |
* open. Default false — a window's |
| 125 |
* bundle is dead weight until the |
| 126 |
* window opens, and the documented |
| 127 |
* contract for it is "publish a |
| 128 |
* render callback on |
| 129 |
* `window.openStationNativeWindows[ |
| 130 |
* <id> ]`", which the shell reads at |
| 131 |
* open time. Opt in only when the |
| 132 |
* bundle ALSO has a boot-time job |
| 133 |
* that must run whether or not the |
| 134 |
* user ever opens the window — a |
| 135 |
* dock badge poller, a public API it |
| 136 |
* installs on `wp.os`. Prefer |
| 137 |
* splitting that job into an |
| 138 |
* always-loaded bundle over paying |
| 139 |
* the whole window's weight on every |
| 140 |
* admin page. |
| 141 |
* @type int $width Initial width (px). Default 520. |
| 142 |
* @type int $height Initial height (px). Default 400. |
| 143 |
* @type int $min_width Minimum width (px). Default 280. |
| 144 |
* @type int $min_height Minimum height (px). Default 220. |
| 145 |
* @type string $placement 'dock' | 'none'. Default 'dock'. |
| 146 |
* 'none' skips the tile (plugin |
| 147 |
* opens the window programmatically). |
| 148 |
* A PROPOSED default only: the user's |
| 149 |
* OpenStation Preferences → Navigation |
| 150 |
* pick wins, and so does a right-click |
| 151 |
* "Keep in dock". |
| 152 |
* @type string $admin 'site' | 'network' | 'any'. Default |
| 153 |
* 'site': offered on every site's |
| 154 |
* shell and never on the network |
| 155 |
* admin's, which is right for a window |
| 156 |
* that reads the current site's REST |
| 157 |
* API. 'network' is the network |
| 158 |
* admin's shell only; 'any' is both. |
| 159 |
* @type string $nav_kind 'app' | 'control'. Default 'app'. |
| 160 |
* What the window IS, which decides |
| 161 |
* where its launcher defaults to (apps |
| 162 |
* to the desktop, controls to the |
| 163 |
* dock) and which dock zone it sits |
| 164 |
* in. Plugins want 'app'; 'control' |
| 165 |
* is for OpenStation's own |
| 166 |
* affordances. |
| 167 |
* @type int $dock_order Sort key among system tiles, |
| 168 |
* ascending; ties keep registration |
| 169 |
* order. Default 0, which places the |
| 170 |
* tile ahead of the shell's own |
| 171 |
* trailing cluster (Mio 10, Overview |
| 172 |
* 20, System 30, Exit 35, Trash 40). |
| 173 |
* Needed because registration order |
| 174 |
* is not something a plugin controls: |
| 175 |
* tiles land when their lazy script |
| 176 |
* resolves. |
| 177 |
* @type bool $placeable Whether the dock tile gets a row in |
| 178 |
* OpenStation Preferences → Apps & |
| 179 |
* Plugins, so the user can move it to |
| 180 |
* the wallpaper or hide it. Defaults |
| 181 |
* to the dock either way. Default |
| 182 |
* false, because most tiles are |
| 183 |
* load-bearing. Opt in for a window |
| 184 |
* the user can reasonably do without. |
| 185 |
* Only offer this on a window that |
| 186 |
* registers no desktop icon: the icon |
| 187 |
* already owns a row of its own. |
| 188 |
* @type string[] $capabilities User capabilities that gate the |
| 189 |
* registration. ANY miss returns |
| 190 |
* `WP_Error openstation_capability_denied`. |
| 191 |
* @type bool|string $autofocus Passed verbatim to |
| 192 |
* `NativeWindowDef.autofocus`. |
| 193 |
* @type string $main_tab_label Label for the "main" tab that |
| 194 |
* displays the window's own |
| 195 |
* `template` output. Only rendered |
| 196 |
* when at least one additional |
| 197 |
* tab is registered via |
| 198 |
* {@see openstation_register_window_tab()}. |
| 199 |
* Defaults to the window's `title`. |
| 200 |
* @type int $main_tab_padding Padding (in px) applied to the |
| 201 |
* auto-generated tab-wrap around |
| 202 |
* the window body. Only applies |
| 203 |
* when additional tabs are |
| 204 |
* registered. Default 16. Pass 0 |
| 205 |
* for edge-to-edge content. |
| 206 |
* Filterable at runtime via |
| 207 |
* `openstation_native_window_tab_wrap_padding`. |
| 208 |
* @type array $config Arbitrary serializable data to ship |
| 209 |
* to the bundle alongside the script |
| 210 |
* tag. Read in JS via |
| 211 |
* `wp.os.getWindowConfig( $id )` |
| 212 |
* (or directly at |
| 213 |
* `window.openStationWindowConfig[ $id ]`). |
| 214 |
* Recommended over `wp_localize_script` |
| 215 |
* for native-window scripts because |
| 216 |
* the lazy-load path bypasses |
| 217 |
* `wp_print_scripts` — passing config |
| 218 |
* through this arg guarantees delivery |
| 219 |
* on both eager AND lazy paths |
| 220 |
* (mid-session activation). Use this |
| 221 |
* for REST URLs, nonces, capability |
| 222 |
* flags, anything session-bound. Empty |
| 223 |
* array (default) ships nothing. |
| 224 |
* } |
| 225 |
* @return true|WP_Error `true` on success; `WP_Error` when any |
| 226 |
* required arg is missing/invalid or a |
| 227 |
* declared capability is unmet. |
