1# Linux window capture
2
3Wayland only. Each capture picks one backend in `LinuxSnapShot.ts` (Hyprland helper, Niri IPC, KDE
4helper, Screenshot portal with active-window target, GNOME extension, then the Electron picker) and
5never falls back to another on failure, cancellation, or denial. A stale `NIRI_SOCKET` or a reachable
6GNOME extension must not select another desktop's backend; session detection comes from
7`XDG_CURRENT_DESKTOP`, in `linuxCaptureSession.ts`.
8
9## Module boundaries
10
11`dbus-next` must only be reached through dynamic imports. `linuxCaptureSession.ts` holds the pure
12helpers (session detection, Niri binding text, portal key mapping, PNG reading) so the main process
13can answer "which desktop is this" without loading a D-Bus client on macOS or Windows.
14
15`patches/dbus-next@0.10.2.patch` removes `usocket` (its optional native Unix-FD transport) and
16connects to both `unix:path=` and `unix:abstract=` buses through Node's `net`. We never pass Unix
17descriptors, and upstream had no `net` fallback for abstract sockets, which `dbus-launch` produces
18outside systemd. Keep the patch when bumping `dbus-next`.
19
20## Accessibility identity
21
22The Screenshot portal returns a PNG URI and no window identity, so portal and picker captures carry
23no accessibility data. Do not infer it from the subsequently focused window or a guessed title.
24
25Native backends supply PID, title, and frame. AT-SPI matching is by PID plus a unique title and size
26match. AT-SPI reports `(0, 0)` for a window's screen position on Wayland even when the compositor
27knows the real one, so only width and height are compared, and descendant coordinates are trusted
28only when the AT-SPI root agrees with the compositor frame and at least one descendant reports a
29distinct position. Otherwise bounds are `null` rather than zero-origin rectangles.
30
31Title matching ignores a single leading Braille CLI spinner frame, since terminals change it between
32capture and lookup. KDE supplies both `frameGeometry` and `clientGeometry`; accept either verified
33size, never a decoration-height tolerance.
34
35On GNOME, browser accessibility bridges need `org.gnome.desktop.interface toolkit-accessibility`
36before the browser starts. Do not toggle it during capture.
37
38## KDE
39
40KWin authorizes `org.kde.KWin.ScreenShot2` by resolving the calling PID's executable against its
41application registry, so the helper is installed at a stable path under the XDG data home with a
42hidden desktop entry, not run from the AppImage mount. Two traps:
43
44- `X-KDE-DBUS-Restricted-Interfaces` uses KConfig's comma-separated list syntax. A trailing
45 semicolon becomes part of the interface name and KWin rejects it.
46- KService's cache key includes search paths and locale. Refresh with `kbuildsycoca6` both directly
47 and through `systemd-run --user`; refreshing only inside the AppImage environment can leave KWin
48 reading stale permissions.
49
50Readiness is checked by calling `CaptureWindow` with an invalid ID and expecting `InvalidWindow`,
51which runs after KWin's authorization check. Files on disk alone never mean ready.
52
53Plasma consumes Shift for shifted digits and produces a punctuation keysym, so a successfully bound
54`Ctrl+Shift+2` may never fire on some layouts. Letter chords work around it. A general fix needs
55layout-aware encoding.
56
57## Hyprland
58
59The helper maps a foreign-toplevel handle to the full 64-bit window address with
60`hyprland-toplevel-mapping-v1` before exporting through `hyprland-toplevel-export-v1`. Never
61truncate the address or pick a window by title.
62
63Hyprland 0.56.2 renders an access-denied texture instead of failing the export frame when consent
64is rejected or a `no_screen_share` rule applies. `ready` is not a permission grant, and pixels must
65not be inspected to guess one. See
66[ScreenshareFrame](https://github.com/hyprwm/Hyprland/blob/v0.56.2/src/managers/screenshare/ScreenshareFrame.cpp).
67
68Hyprland's GlobalShortcuts portal registers actions, not key chords. `shortcutActionRegistered` is
69distinct from `shortcutRegistered`; nothing in the UI may claim the keys are reserved.
70
71The bundled protocol XML ships with the helper because its BSD license requires the notice.
72
73## Niri
74
75Niri does not implement the global-shortcut portal. While capture is enabled the app owns
76`<app-id>.SnapShot` on the session bus and exports `com.t3tools.SnapShot.Capture`; the config
77binding spawns `gdbus` to call it. Development and packaged app IDs use separate names so a dev
78build does not steal the user's binding.
79
80Niri supplies no global screenshot origin, so AT-SPI matching uses logical size and title only.
81
82## Config edits
83
84`CaptureShortcutConfig` edits user dotfiles. The invariants: opening setup never reads the file;
85**Review changes** is the read consent; the renderer only ever sees before/after text over trusted
86desktop IPC; **Save** sends a proposal ID and the desktop re-verifies bytes, inode, mode, and
87includes against the snapshot it previewed before writing. Writes go through a staged temp file and
88atomic rename with a backup beside the original. Niri validates the staged file first.
89
90Modifier serialization writes Linux `Ctrl` explicitly, never the cross-platform `mod` alias.
91
92## GNOME extension
93
94Source in `apps/desktop/gnome-extension`, UUID `snap-shot@t3.codes`. GNOME only discovers a newly
95installed extension at login, so setup distinguishes "installed, needs logout" from "discovered but
96disabled" and compares loaded and installed versions.
97
98The extension trusts callers that own `com.t3tools.T3Code.SnapShot` (or the `.Development`
99variant) on the same connection. This is GNOME's trusted-session-client pattern, not authentication
100against a hostile process on the user's bus.
101
102Electron does not position overlay windows on Wayland, so the flash and flight run as Shell actors
103inside the extension with coordinates relative to T3's content area. Electron 44's restored-session
104path can skip rebinding and leave callbacks behind on unregister, which is why
105`PortalCaptureShortcut` owns its own portal session instead of using Electron's global-shortcut API.
106
107GNOME 50 removed `Meta.is_wayland_compositor`. Shell internals change across majors; verify each
108version before adding it to `metadata.json`.

66The Electron shell acquires `DesktopPreReadyPlatform.layer` synchronously before asynchronous
67services. On Linux this sets the desktop-entry identity and global-shortcut portal flags before
68Chromium initializes its portal connection. Setting the identity later in `DesktopAppIdentity`
69is too late: Chromium caches the first registration, including failures. The identity must match
70the installed entry managed by `DesktopLinuxUrlHandler`. Pre-ready setup also refreshes that entry's
71`Exec` path before portal registration: AppImage updates can remove the previous executable, which
72makes the old entry invalid even though its filename is correct. The later URL handler avoids
73rewriting an identical entry while the portal may be reading it. On Wayland, Electron's synchronous
74shortcut-registration result only confirms submission; it does not confirm desktop consent or
75an active binding.
76
77Native modules never load in the Electron main process on the startup path, and the two the
78snapshot feature keeps are isolated: `@crowecawcaw/xa11y` runs only in forked Node-mode children
79(`SnapShotAccessibilityWorker`, `RegionSnapShotWorker`) and a worker thread, and `ffi-rs` loads
80lazily inside `WindowsForeground.ts` for a handful of Win32 calls. macOS window lookup shells out
81to `osascript` instead of a native addon. A crash or stall in any of these must not take the app
82down, so new native capability goes in a child with a deadline, not an `import` in main.

1# SnapShots
2
3A SnapShot captures the window you are working in and attaches it to your current draft. The
4attachment carries the app name and window title, and when available the app icon and the window's
5accessibility data (its controls, text, and their positions in the image). Agents can use that data
6to reason about the screenshot.
7
8SnapShots are off by default and available in the desktop app on macOS, Windows, and Linux with
9Wayland. X11 sessions are not supported.
10
11## Turning it on
12
13Open **Settings** > **SnapShots** and turn the feature on. Setup has two steps: allow capture, then
14choose a shortcut. Each step shows only what your desktop needs. **Finish later** turns capture back
15off but keeps anything you already installed, so you can resume where you left off.
16
17- **macOS** asks for Screen Recording during setup. It asks for Accessibility only when **Include
18 app text** is on.
19- **Windows** needs no setup or permission.
20- **Linux** depends on your desktop. See [Linux desktops](#linux-desktops).
21
22Turning capture off releases the shortcut. It does not uninstall a helper or extension you installed.
23
24## Taking a capture
25
26Switch to the window you want and press the shortcut. The default on macOS and Windows is both
27Shift keys together. T3 Code attaches the image to your draft and brings itself forward. If no thread
28is open it starts a draft in the current project.
29
30Pressing the shortcut while T3 Code is in front captures T3 Code itself.
31
32Pending captures are kept on disk until the attachment is saved to the draft, so a capture survives
33closing the app mid-way and is attached on the next launch. Captures rejected because the image is
34too large are discarded.
35
36## Changing the shortcut
37
38Select the shortcut in Settings, press the new keys, then **Save**. On macOS and Windows you can use
39a modifier pair such as Command+Command or Ctrl+Ctrl, or a key chord. T3 Code refuses shortcuts
40that collide with its own keybindings or that the operating system already reserves.
41
42On Linux, choose a key chord; modifier pairs are not supported. On Niri and Hyprland the shortcut
43lives in your compositor config, so **Change shortcut** reopens setup to review the change.
44
45## Include app text
46
47**Include app text** controls whether captures include the window's accessibility data. Turn it off
48to attach screenshots only. On macOS this also drops the Accessibility permission requirement.
49
50Availability depends on the app. Some apps expose only their window controls, not the document or
51terminal contents. If an app is slow to answer, T3 Code attaches the screenshot without the data
52rather than waiting.
53
54On GNOME, browsers may need app accessibility enabled in the desktop's accessibility settings before
55they expose text. Restart the browser after enabling it.
56
57An icon beside the app name on an attachment shows whether accessibility data was included. Select
58it to inspect what was captured.
59
60## Sound, flash, and animation
61
62Settings controls the capture sound, the brief flash on the captured window, and the animation that
63flies the image into your draft. Each can be turned off independently. The operating system's
64reduced-motion setting also disables the animation.
65
66## Linux desktops
67
68SnapShots work on Wayland sessions. Each desktop provides capture differently, and setup names your
69current desktop and shows only what it needs. Preferences carry across desktops, but each desktop's
70helper and shortcut approval are separate.
71
72**GNOME.** Install the bundled **T3 Code SnapShots** extension during setup. It is installed
73per-user, offline, and needs no administrator password. Sign out and back in after the first
74install so GNOME discovers it, then enable it from setup or from GNOME's Extensions app. If GNOME
75has disabled all user extensions, turn them on there first. Disable or remove the extension in
76GNOME's Extensions app to revoke access.
77
78**KDE Plasma 6.** Install the bundled capture helper during setup; no sign-out is needed. If the
79shortcut does not fire, check T3 Code under **System Settings** > **Keyboard** > **Shortcuts**. If a
80shortcut using Shift and a number does not work on your keyboard layout, use a letter chord instead.
81Remove the helper from **Manage capture** > **Access** > **Advanced**.
82
83**Hyprland and Omarchy.** Install the bundled helper during setup, then choose a shortcut and select
84**Review changes**. T3 Code shows the exact change it will make to your Hyprland config. **Save
85shortcut** writes only that change, keeps a backup, and reloads Hyprland. Approve the screen-sharing
86prompt for the helper if one appears. On Omarchy, bind in your own config, not the shipped defaults.
87Some Hyprland versions return an "access denied" image instead of an error when capture is blocked;
88check the helper's screen-sharing permission.
89
90**Niri.** Choose a shortcut and select **Review changes**. T3 Code shows the exact binding it will

89 When created, a series of buffer events will be sent, each representing a
90 supported buffer type. The "buffer_done" event is sent afterwards to
91 indicate that all supported buffer types have been enumerated. The client
92 will then be able to send a "copy" request. If the capture is successful,
93 the compositor will send a "flags" followed by a "ready" event.
94
95 wl_shm buffers are always supported, ie. the "buffer" event is guaranteed to be sent.
96
97 If the capture failed, the "failed" event is sent. This can happen anytime
