+snot - suckless notification daemon
+==================================
+
+snot is a simple notification daemon for Wayland compositors implementing the 
+layer-shell protocol.
+
+Requirements
+-----------
+* wayland
+* wlroots
+* cairo
+* pango
+* dbus
+
+Installation
+-----------
+Edit config.mk to match your local setup (snot is installed into
+/usr/local by default).
+
+Afterwards enter the following command to build and install snot
+(if necessary as root):
+
+    make clean install
+
+Configuration
+------------
+The configuration of snot is done by creating a custom config.h
+and (re)compiling the source code.
+
+    cp config.def.h config.h
+    $EDITOR config.h
+    make clean snot

+      Backward incompatible changes are done by bumping the version

+      interface version. Once the protocol is to be declared stable,

+      rendered with a defined z-depth respective to each other. They may also be
+      anchored to the edges and corners of a screen and specify input handling
+      semantics. This interface should be suitable for the implementation of

+        Create a layer surface for an existing surface. This assigns the role of
+        layer_surface, or raises a protocol error if another role is already
+        assigned.
+
+        Creating a layer surface from a wl_surface which has a buffer attached
+        or committed is a client error, and any attempts by a client to attach
+        or manipulate a buffer prior to the first layer_surface.configure call
+        must also be treated as errors.
+
+        After creating a layer_surface object and setting it up, the client
+        must perform an initial commit without any buffer attached.
+        The compositor will reply with a layer_surface.configure event.
+        The client must acknowledge it and is then allowed to attach a buffer
+        to map the surface.
+
+        You may pass NULL for output to allow the compositor to decide which
+        output to use. Generally this will be the one that the user most
+        recently interacted with.
+

+
+      Layer surface state (layer, size, anchor, exclusive zone,
+      margin, interactivity) is double-buffered, and will be applied at the
+      time wl_surface.commit of the corresponding wl_surface is called.
+
+      Attaching a null buffer to a layer surface unmaps it.
+
+      Unmapping a layer_surface means that the surface cannot be shown by the
+      compositor until it is explicitly mapped again. The layer_surface
+      returns to the state it had right after layer_shell.get_layer_surface.

+        surfaces. The compositor's use of this information is
+        implementation-dependent - do not assume that this region will not
+        actually be occluded.
+
+        A positive value is only meaningful if the surface is anchored to one
+        edge or an edge and both perpendicular edges. If the surface is not
+        anchored, anchored to only two perpendicular edges (a corner), anchored
+        to only two parallel edges or anchored to all edges, a positive value
+        will be treated the same as zero.
+
+        A positive zone is the distance from the edge in surface-local
+        coordinates to consider exclusive.
+
+        Surfaces that do not wish to have an exclusive zone may instead specify
+        how they should interact with surfaces that do. If set to zero, the
+        surface indicates that it would like to be moved to avoid occluding
+        surfaces with a positive exclusive zone. If set to -1, the surface
+        indicates that it would not like to be moved to accommodate for other
+        surfaces, and the compositor should extend it all the way to the edges
+        it is anchored to.
+
+        For example, a panel might set its exclusive zone to 10, so that
+        maximized shell surfaces are not shown on top of it. A notification
+        might set its exclusive zone to 0, so that it is moved to avoid
+        occluding the panel, but shell surfaces are shown underneath it. A
+        wallpaper or lock screen might set their exclusive zone to -1, so that
+        they stretch below or over the panel.

+        in keyboard events and not allowing them to be focused can improve the
+        desktop experience; (2) some applications will want to take exclusive
+        keyboard focus.

+          This value indicates that this surface is not interested in keyboard
+          events and the compositor should never assign it the keyboard focus.
+
+          This is the default value, set for newly created layer shell surfaces.
+
+          This is useful for e.g. desktop widgets that display information or
+          only have interaction with non-keyboard input devices.

+          Request exclusive keyboard focus if this surface is above the shell surface layer.
+
+          For the top and overlay layers, the seat will always give
+          exclusive keyboard focus to the top-most layer which has keyboard
+          interactivity set to exclusive. If this layer contains multiple
+          surfaces with keyboard interactivity set to exclusive, the compositor
+          determines the one receiving keyboard events in an implementation-
+          defined manner. In this case, no guarantee is made when this surface
+          will receive keyboard focus (if ever).
+
+          For the bottom and background layers, the compositor is allowed to use
+          normal focus semantics.
+
+          This setting is mainly intended for applications that need to ensure
+          they receive all keyboard events, such as a lock screen or a password
+          prompt.

+          This requests the compositor to allow this surface to be focused and
+          unfocused by the user in an implementation-defined manner. The user
+          should be able to unfocus this surface even regardless of the layer
+          it is on.
+
+          Typically, the compositor will want to use its normal mechanism to
+          manage keyboard focus between layer shell surfaces with this setting
+          and regular toplevels on the desktop layer (e.g. click to focus).
+          Nevertheless, it is possible for a compositor to require a special
+          interaction to focus or unfocus layer shell surfaces (e.g. requiring
+          a click even if focus follows the mouse normally, or providing a
+          keybinding to switch focus between layers).
+
+          This setting is mainly intended for desktop shell components (e.g.
+          panels) that allow keyboard interaction. Using this option can allow
+          implementing a desktop shell that can be fully usable without the
+          mouse.

+    <description summary="desktop user interface surface base interface">
+      An interface that may be implemented by a wl_surface, for
+      implementations that provide a desktop-style user interface.
+
+      It provides a base set of functionality required to construct user
+      interface elements requiring management by the compositor, such as
+      toplevel windows, menus, etc. The types of functionality are split into
+      xdg_surface roles.
+
+      Creating an xdg_surface does not set the role for a wl_surface. In order
+      to map an xdg_surface, the client must create a role-specific object
+      using, e.g., get_toplevel, get_popup. The wl_surface for any given
+      xdg_surface can have at most one role, and may not be assigned any role
+      not based on xdg_surface.
+
+      A role must be assigned before any other requests are made to the
+      xdg_surface object.
+
+      The client must call wl_surface.commit on the corresponding wl_surface
+      for the xdg_surface state to take effect.
+
+      Creating an xdg_surface from a wl_surface which has a buffer attached or
+      committed is a client error, and any attempts by a client to attach or
+      manipulate a buffer prior to the first xdg_surface.configure call must
+      also be treated as errors.
+
+      After creating a role-specific object and setting it up (e.g. by sending
+      the title, app ID, size constraints, parent, etc), the client must
+      perform an initial commit without any buffer attached. The compositor
+      will reply with initial wl_surface state such as
+      wl_surface.preferred_buffer_scale followed by an xdg_surface.configure
+      event. The client must acknowledge it and is then allowed to attach a
+      buffer to map the surface.
+
+      Mapping an xdg_surface-based role surface is defined as making it
+      possible for the surface to be shown by the compositor. Note that
+      a mapped surface is not guaranteed to be visible once it is mapped.
+
+      For an xdg_surface to be mapped by the compositor, the following
+      conditions must be met:
+      (1) the client has assigned an xdg_surface-based role to the surface
+      (2) the client has set and committed the xdg_surface state and the
+	  role-dependent state to the surface
+      (3) the client has committed a buffer to the surface
+
+      A newly-unmapped surface is considered to have met condition (1) out
+      of the 3 required conditions for mapping a surface if its role surface
+      has not been destroyed, i.e. the client must perform the initial commit
+      again before attaching a buffer.

+      This interface defines an xdg_surface role which allows a surface to,
+      among other things, set window-like properties such as maximize,
+      fullscreen, and minimize, set application-specific metadata like title and
+      id, and well as trigger user interactive operations such as interactive
+      resize and move.
+
+      A xdg_toplevel by default is responsible for providing the full intended
+      visual representation of the toplevel, which depending on the window
+      state, may mean things like a title bar, window controls and drop shadow.
+
+      Unmapping an xdg_toplevel means that the surface cannot be shown
+      by the compositor until it is explicitly mapped again.
+      All active operations (e.g., move, resize) are canceled and all
+      attributes (e.g. title, state, stacking, ...) are discarded for
+      an xdg_toplevel surface when it is unmapped. The xdg_toplevel returns to
+      the state it had right after xdg_surface.get_toplevel. The client
+      can re-map the toplevel by performing a commit without any buffer
+      attached, waiting for a configure event and handling it as usual (see
+      xdg_surface description).
+
+      Attaching a null buffer to a toplevel unmaps the surface.

+      A popup surface is a short-lived, temporary surface. It can be used to
+      implement for example menus, popovers, tooltips and other similar user
+      interface concepts.
+
+      A popup can be made to take an explicit grab. See xdg_popup.grab for
+      details.
+
+      When the popup is dismissed, a popup_done event will be sent out, and at
+      the same time the surface will be unmapped. See the xdg_popup.popup_done
+      event for details.
+
+      Explicitly destroying the xdg_popup object will also dismiss the popup and
+      unmap the surface. Clients that want to dismiss the popup when another
+      surface of their own is clicked should dismiss the popup using the destroy
+      request.
+
+      A newly created xdg_popup will be stacked on top of all previously created
+      xdg_popup surfaces associated with the same xdg_toplevel.
+
+      The parent of an xdg_popup must be mapped (see the xdg_surface
+      description) before the xdg_popup itself.
+
+      The client must call wl_surface.commit on the corresponding wl_surface
+      for the xdg_popup state to take effect.

+      <description summary="make the popup take an explicit grab">
+	This request makes the created popup take an explicit grab. An explicit
+	grab will be dismissed when the user dismisses the popup, or when the
+	client destroys the xdg_popup. This can be done by the user clicking
+	outside the surface, using the keyboard, or even locking the screen
+	through closing the lid or a timeout.
+
+	If the compositor denies the grab, the popup will be immediately
+	dismissed.
+
+	This request must be used in response to some sort of user action like a
+	button press, key press, or touch down event. The serial number of the
+	event should be passed as 'serial'.
+
+	The parent of a grabbing popup must either be an xdg_toplevel surface or
+	another xdg_popup with an explicit grab. If the parent is another
+	xdg_popup it means that the popups are nested, with this popup now being
+	the topmost popup.
+
+	Nested popups must be destroyed in the reverse order they were created
+	in, e.g. the only popup you are allowed to destroy at all times is the
+	topmost one.
+
+	When compositors choose to dismiss a popup, they may dismiss every
+	nested grabbing popup as well. When a compositor dismisses popups, it
+	will follow the same dismissing order as required from the client.
+
+	If the topmost grabbing popup is destroyed, the grab will be returned to
+	the parent of the popup, if that parent previously had an explicit grab.
+
+	If the parent is a grabbing popup which has already been dismissed, this
+	popup will be immediately dismissed. If the parent is a popup that did
+	not take an explicit grab, an error will be raised.
+
+	During a popup grab, the client owning the grab will receive pointer
+	and touch events for all their surfaces as normal (similar to an
+	"owner-events" grab in X11 parlance), while the top most grabbing popup
+	will always have keyboard focus.
