This patch adds support for window focusing, and sending events back
to the client application when a notification is closed.
* Refactor notification related configuration options:
- add desktop-notifications sub-section
- deprecate 'notify' in favor of 'desktop-notifications.command'
- deprecate 'notify-focus-inhibit' in favor of
'desktop-notifications.inhibit-when-focused'
* Refactor: rename 'struct kitty_notification' to 'struct
notification'
* Pass a 'struct notification' to notify_notify(), instead of many
arguments.
* notify_notify() now registers a reaper callback. When the notifier
process has terminated, the notification is considered closed, and we
either try to focus (activate) the window, or send an event to the
client application, depending on the notification setting.
* For the window activation, we need an XDG activation token. For now,
assume *everything* written on stdout is part of the token.
* Refactor: remove much of the warnings from OSC-99; we don't
typically log anything when an OSC/CSI has invalid values.
* Add icon support to OSC-99. This isn't part of the upstream
spec. Foot's implementation:
- uses the 'I' parameter
- the value is expected to be a symbolic icon name
- a quick check for absolute paths is done, and such icon requests
are ignored.
* Added ${icon} to the 'desktop-notifications.command' template. Uses
the icon specified in the notification, or ${app-id} if not set.
This adds limited support for OSC-99, kitty desktop notifications[^1]. We
support everything defined by the "protocol", except:
* 'a': action to perform on notification activation. Since we don't
trigger the notification ourselves (over D-Bus), we don't know a)
which ID the notification got, or b) when it is clicked.
* ... and that's it. Everything else is supported
To be explicit, we *do* support:
* Chunked notifications (d=0|1), allowing the application to append
data to a notification in chunks, before it's finally displayed.
* Plain UTF-8, or base64-encoded UTF-8 payload (e=0|1).
* Notification identifier (i=xyz).
* Payload type (p=title|body).
* When to honor the notification (o=always|unfocused|invisible), with
the following quirks:
- we don't know when the window is invisible, thus it's treated as
'unfocused'.
- the foot option 'notify-focus-inhibit' overrides 'always'
* Urgency (u=0|1|2)

This adds support for a new OSC escape sequence: OSC 176, that lets
terminal programs tell the terminal the name of the app that is
running. foot then sets the app ID of the toplevel to that ID,
which lets the compositor know which app is running, and typically
sets the appropriate icon, window grouping, ...

First, add a ‘token’ argument to spawn(). When non-NULL, spawn() will
set the ‘XDG_ACTIVATION_TOKEN’ environment variable in the forked
process. If DISPLAY is non-NULL, we also set DESKTOP_STARTUP_ID, for
compatibility with X11 applications. Note that failing to set either
of these environment variables are considered non-fatal - i.e. we
ignore failures.
Next, add a helper function, wayl_get_activation_token(), to generate
an XDG activation token, and call a user-provided callback when it’s
‘done (since token generation is asynchronous). This function takes an
optional ‘seat’ and ‘serial’ arguments - when both are non-NULL/zero,
we set the serial on the token. ‘win’ is a required argument, used to
set the surface on the token.
Re-write wayl_win_set_urgent() to use the new helper function.
Finally, rewrite activate_url() to first try to get an activation
token (and spawn the URL launcher in the token callback). If that
fails, or if we don’t have XDG activation support, spawn the URL
launcher immediately (like before this patch).
Closes#1058
foot doesn't show desktop notifications (via OSC777) if the current
terminal has keyboard focus.
This is probably a sane default, but there are use cases where showing
a notification regardless of the focus status may be desired. For
example, a completion notification of a long running task inside a
non-focused tmux window.
This PR adds the notify-focus-inhibit option which can be used to
disable inhibition of notifications when the window has focus.
The default value is `yes`, which retains the old behavior.
