The `app` feature (App / run_app, AppConfig, SiteHooks): registers the Tauri plugins every app
uses (single-instance, deep-link and updater opt-in, window-state, opener, process, notification,
dialog), makes app data, loads profiles and the language, builds the window (restore, lost-geometry
reset, helper-close routing, native resize follow) and the transparent shell, and serves tabs_sync,
tab_navigate, tab_action, open_external_url, shell_focus, shell_raise, window_system_menu,
profiles_get/set, i18n_get/set (shell-only) and tab_shortcut, tab_link_drag (tab-only). The tab
builder is generic; the app fills in SiteHooks. `commands` lists them (manifest() for build.rs),
`testkit` checks capability files and caller guards, i18n::page_script is origin-guarded.
check:tauri now checks the app feature.
tab-bridge.js (moved from wayBetter for X) is served by bridge::SOURCE,
or by bridge::script(BridgeOptions) with shortcut and link-drag
forwarding switched off for a shell that does not handle them (a
forwarded shortcut is taken from the page). Tests: one options line,
only tab_report/tab_shortcut/tab_link_drag, every forwarded shortcut is
one tabs::valid_shortcut accepts. Generated apps now inject
bridge::script(BridgeOptions::REPORT_ONLY) instead of writing their own
duplicated src-tauri/runtime/tab-bridge.js.
updater (tauri + net features): the launch handshake, the cached hotfix
(re-verified on every load), the 30 min +/- 5 check loop, download and
verification through tauri-plugin-updater, the size-capped hotfix fetch
(no identifiers), hotfix delivery to the site's tabs, and status/apply/
ready for the app's shell-only commands. An UpdaterConfig carries what
differs per app: SiteSpec, hotfix URL and public key, page global/event,
manual download page, user agent and the "update ready" hook.
gfonts (pure): CSS2 API URLs, the fonts.googleapis.com/fonts.gstatic.com
allowlist, CSS parsing and face selection, woff2 checks, the sha256
manifest cache format and the page script, whose origin guard and
runtime global now come from the SiteSpec. fonts (net feature): the
download client (allowlist re-checked per request, no redirects, size
caps), the family/preview caches and install/remove/faces/preview for the
app's shell-only commands. Tests and CSS fixtures moved with them.
media: gallery settings (absolute folders, deduplicated), listing and
resolving images only directly inside owner-chosen folders (links must
stay inside), data URLs, the bounded clipboard history with its index
and image files, PNG encoding. media::clipboard (tauri feature): reading
the OS clipboard, the Windows change counter, skipping copies marked
private by password managers, and the opt-in polling loop (records from
the next copy after opting in; releases the clipboard while off).
The alerts commit was locked against the tree before the store module
landed and dropped the store's packages (ed25519-dalek, reqwest, ...);
this is the store commit's lockfile plus tauri-plugin-notification.
alerts: keyword settings (normalized, deduplicated, bounded), the
configured-keyword check, plain bounded snippets, the per-keyword and
global Throttle and an AlertGate over any KeywordMatch (one notification
per item). With the tauri feature, alerts::notify shows a native OS
notification (tauri-plugin-notification, registered by the app).
Moved from wayBetter for X (distribution.rs + desktop_store.rs) so every wayBetter app gets the
Store; the app keeps its Tauri command wrappers and a `StoreConfig`.
- store::catalog (pure): `StoreConfig` (app id in the shared catalog, product, user agent, link
scheme, store URL, public keys, allowed hosts), `AllowedHost` (raw-files-only rule for a code
host; DEFAULT_HOSTS = waybetter.fyi, cdn1.crt.fyi, git.crt.fyi raw), install-link parsing,
download allow-list, theme validation, catalog format 2: every item names its `apps`; the whole
catalog is verified (Ed25519 over the exact bytes with any listed key, so keys rotate; strict
schema; ids/files unique per app) and each app gets only its own items (another app's item is
shape-checked but not held to this app's hosts); per-item sha256/size, install records, versions.
- store::install: `Store` (pending links, staged installs with TTL/bound, MIN_REVIEW before a
commit, commit writes exactly the staged bytes after re-validation via PluginStore::install,
plugin remove, records file, verified catalog + offline copy verified again when read back,
StoreView). Plugin start/stop scripts run through a function the app passes.
- store::net (`net` feature): no-redirect, no-cookie reqwest fetch with caps; stage_link,
stage_item, catalog(refresh).
- Tests: links, per-app allow-lists and schemes, themes, signatures incl. tampering and key
rotation, multi-app filtering, bad items, staging/commit/remove/records/offline copy on disk,
fetch refuses anything off the allow-list. test:rust and check:tauri build with `net`.
plugins::commands: the palette commands a site tab reports (validated and
capped as a whole) and the page script that runs one, now built from the
SiteSpec (runtime global, primary origin) instead of a hard-coded x.com.
devmode: the debounced polling watcher (plugins, custom.css, one theme
file), reload order, DevError and theme-file reading; the app turns the
document into its own theme state through a callback.
Named tab/pane/deck layouts, bounded and well-formed (slug ids, 1-60
character names, known tab kinds, http(s) URLs, size caps), moved from
the wayBetter for X app unchanged with its tests.
backup: the versioned .waybetter envelope (format/version checks, only the
app's registered sections kept), secret-key scrubbing, the plugins /
customCss / accounts sections every app has, plugin import checks and
atomic writes. sync: Argon2id + XChaCha20-Poly1305 snapshots of the
settings backup in a folder the owner syncs, moved unchanged from the
wayBetter for X app with its tests.
- runtime/i18n.ts: ICU-lite messages (placeholders as text, Intl.PluralRules plurals with exact
forms, selectordinal, select, number/date/time), fallback chains (pt-BR -> pt -> en, ar-x-fm ->
ar), X and legacy code aliases, RTL by locale, lazy catalogs, live onChange. Apostrophes are
literal except right before { } # or another apostrophe.
- runtime/i18nCheck.ts: rules for contributed catalogs (shape, keys, syntax, placeholder parity,
select options, markup/control characters, lengths). An argument English only uses to choose a
plural form may be dropped; missing plural forms are warnings; meta "allowEmpty" fragments.
- runtime/pluginI18n.ts: api.i18n bound per plugin (register/t/locale/dir/onChange/number/date/
relative/list); the UI kit's own words follow the app's language. pageLang.ts reports the
site's <html lang>. shell/messages.ts: shell-model words.
- waybetter-host i18n.rs: NativeStrings (validated plain text, caps, one-pass {name} fill, page
payload by prefix), system_locales via sys-locale; TabState.lang.
- JSON Schemas for catalogs and translator notes; npm exports waybetter/i18n, /i18n/check,
/i18n/plugin.
layout.rs (headless, tested): Placements remembers each tab webview's last rectangle and
visibility, so a tabs_sync that changes nothing makes no native call and one that moves one
pane touches one webview; Frame/follow_rect estimate where panes go when the window size
changes (outer margins fixed, proportional in between, shared borders stay shared).
host.rs: place_tab/forget_tab use it; place_child is a single set_bounds (one WebView2
SetBounds instead of a move then a resize, each a page re-layout); follow_window_resizes
re-places visible tabs from the window's own Resized events on the main thread, before the
shell lays out again, and keeps WindowMetrics current so a sync needs no blocking round
trips for the window size; layout_window says when a layout was made for a stale size.
Linux: the shell becomes a GtkOverlay layer itself (an empty box is the base) and is
re-ordered to the top or bottom of the overlay; a tab placed while it is raised goes under
it. macOS: the shell's WKWebView is re-ordered among its superview's subviews
(addSubview:positioned:relativeTo:), keeping the first responder if it was in the shell.
Both now report support, so overlays no longer hide the tabs there either (the app makes the
shell webview transparent; macOS needs tauri's macos-private-api).
Windows: a tab webview about to be hidden hands the shell its last frame (WebView2
CapturePreview, JPEG, `tab-still` event), for its pane to show instead of an outline while
no webview is on screen there.
- host plugins.rs: PERMISSIONS, parse_permissions, ScriptPlugin.permissions/problems (None = legacy,
full API), validate_plugin (file name, 2 MiB, UTF-8 text without binary bytes, header with @name
and @version, valid @permissions, network:none refused when the code calls network APIs),
source_findings, PluginStore::install (atomic rename, never enables, keeps the enabled state on
update) / remove / is_enabled / file_hash. start/stop scripts run the module body, construction,
start() and stop() inside window.<global>.withPlugin(id, grants, fn) when the runtime has it.
- runtime permissions.ts: parsePermissions, scopePluginApi (undeclared gated members throw a
PluginPermissionError; scope().ui gated like api.ui), createPluginContext (the view of the plugin
whose code runs; legacy = full API). A declaration and guard rail, not a sandbox.
- The `commands` permission name comes from the parallel palette-commands work (its API lands there).
tao's thread event target and the single-instance message window are visible
1 px unowned top-level windows. taskkill /PID (WM_CLOSE, no /F) closes only the
first such window in z-order; a minimized app window sinks below them, so the
close destroyed a helper and the app kept running. route_helper_closes
subclasses those helpers and forwards WM_CLOSE to the app window.
- plugin: *.plugin.js with the store header and start/stop on api.scope, storage, observe,
onKey, the UI kit (toast with action, ui.h settings dialog) and api.theme/--wb-* vars;
--ts makes a TypeScript project typed by the waybetter package (build keeps the header first)
- theme: JSON with "$schema" -> theme.schema.json, palette derived like themeFromColors,
font roles (family, tweet), presets
- app: Tauri 2 + waybetter-host + runtime + shell models: SiteSpec, SiteAdapter, shell/tab-chrome/
site-tab capabilities, tabs_sync, plugin store, a site-only command; presets for youtube.com,
kick.com, twitch.tv with placeholder selectors; host crate via submodule, path or git
- tests generate into temp dirs: headers via parse_meta (new plugin_meta example), plugin code
against createCorePluginApi's members, themes against the schema, app TS with tsc against the
built package, app Rust with cargo metadata/check/test
- wired into bun run check (typecheck incl. checkJs, build:packages, test:create) and pack:check
tauri 2 (runtime-wry build_gtk with the window's GtkBox) packs every child
webview into the window box, stacked and with set_position/set_size ignored,
so tab webviews landed under the shell instead of over their panes.
place_child/attach_shell move them into a GtkOverlay (shell as base layer)
and allocate each at its exact rect via get-child-position; placed_rect
reports the placement (GTK children have no position). Windows/macOS keep
set_position/set_size.
set_tab_visible shows/hides a tab webview and sets
ICoreWebView2_19::SetMemoryUsageTargetLevel (LOW when hidden, NORMAL when
shown). Hidden tabs keep running; the browser trims their working set.
Site-agnostic parts of the X app, behind a small site adapter:
- crates/waybetter-host: webview-label security policy and tab rect
clamp, account profiles with native-owned accounts (AccountRules),
plugin store with bundled-plugin upgrades (PluginHost), signed
data-only hotfix channel, update scheduling and crash handshake, tab
payloads/link routing/tab-chrome validation, and (feature "tauri")
webview helpers and the Windows system menu.
- packages/runtime: DOM hub, request hub, plugin API core, OKLab theme
color model, split-view rail hiding, link routing and account
reporting, each configured by a SiteAdapter.
- packages/shell: address bar, pane, link-drop, profile, palette and
update-chip models, and window controls with the Tauri API injected.
Tests moved/adapted from the app: 45 Rust (headless), 40 TypeScript.
