The main goal of this project is to provide a similar feel to openbox but on wayland The main goal of this project is to provide a similar feel to openbox but on wayland
### Expectations ### Dependencies
I'm in school and working part-time but I will try my best to work on this and
continue to improve it. *-wlroots
*-wayland
### Build instructions
```
meson build
cd build
ninja
```
After that, you should have an executable in build/

<description summary="Primary selection protocol">
This protocol provides the ability to have a primary selection device to
match that of the X server. This primary selection is a shortcut to the
common clipboard selection, where text just needs to be selected in order
to allow copying it elsewhere. The de facto way to perform this action
is the middle mouse button, although it is not limited to this one.
Clients wishing to honor primary selection should create a primary
selection source and set it as the selection through
wp_primary_selection_device.set_selection whenever the text selection
changes. In order to minimize calls in pointer-driven text selection,
it should happen only once after the operation finished. Similarly,
a NULL source should be set when text is unselected.
wp_primary_selection_offer objects are first announced through the
wp_primary_selection_device.data_offer event. Immediately after this event,
the primary data offer will emit wp_primary_selection_offer.offer events
to let know of the mime types being offered.
When the primary selection changes, the client with the keyboard focus
will receive wp_primary_selection_device.selection events. Only the client
with the keyboard focus will receive such events with a non-NULL
wp_primary_selection_offer. Across keyboard focus changes, previously
focused clients will receive wp_primary_selection_device.events with a
NULL wp_primary_selection_offer.
In order to request the primary selection data, the client must pass
a recent serial pertaining to the press event that is triggering the
operation, if the compositor deems the serial valid and recent, the
wp_primary_selection_source.send event will happen in the other end
to let the transfer begin. The client owning the primary selection
should write the requested data, and close the file descriptor
immediately.
If the primary selection owner client disappeared during the transfer,
the client reading the data will receive a
wp_primary_selection_device.selection event with a NULL
wp_primary_selection_offer, the client should take this as a hint
to finish the reads related to the no longer existing offer.
The primary selection owner should be checking for errors during
writes, merely cancelling the ongoing transfer if any happened.

<description summary="Server side window decoration manager">
This interface allows to coordinate whether the server should create

When a client creates a server-side decoration object it indicates
that it supports the protocol. The client is supposed to tell the
server whether it wants server-side decorations or will provide
client-side decorations.
If the client does not create a server-side decoration object for
a surface the server interprets this as lack of support for this
protocol and considers it as client-side decorated. Nevertheless a
client-side decorated surface should use this protocol to indicate
to the server that it does not want a server-side deco.

edge, rather than a corner. The zone is the number of surface-local
coordinates from the edge that are considered 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 excluzive 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.
The default value is 0.
Exclusive zone is double-buffered, see wl_surface.commit.

Requests that the surface be placed some distance away from the anchor
point on the output, in surface-local coordinates. Setting this value

The exclusive zone includes the margin.
Margin is double-buffered, see wl_surface.commit.

Set to 1 to request that the seat send keyboard events to this layer
surface. For layers below the shell surface layer, the seat will use
normal focus semantics. For layers above the shell surface layers, the
seat will always give exclusive keyboard focus to the top-most layer
which has keyboard interactivity set to true.
Layer surfaces receive pointer, touch, and tablet events normally. If
you do not want to receive them, set the input region on your surface
to an empty region.

This assigns an xdg_popup's parent to this layer_surface. This popup
should have been created via xdg_surface::get_popup with the parent set

<description summary="ack a configure event">
When a configure event is received, if a client commits the
surface in response to the configure event, then the client
must make an ack_configure request sometime before the commit
request, passing along the serial of the configure event.
If the client receives multiple configure events before it
can respond to one, it only has to ack the last configure event.
A client is not required to commit immediately after sending
an ack_configure request - it may even ack_configure several times
before its next surface commit.
A client may send multiple ack_configure requests before committing, but
only the last request sent before a commit indicates which configure
event the client really is responding to.

<event name="configure">
<description summary="suggest a surface change">
The configure event asks the client to resize its surface.
Clients should arrange their surface for the new states, and then send
an ack_configure request with the serial sent in this configure event at
some point before committing the new surface.
The client is free to dismiss all but the last configure event it
received.
The width and height arguments specify the size of the window in
surface-local coordinates.
The size is a hint, in the sense that the client is free to ignore it if
it doesn't resize, pick a smaller size (to satisfy aspect ratio or
resize in steps of NxM pixels). If the client picks a smaller size and
is anchored to two opposite anchors (e.g. 'top' and 'bottom'), the
surface will be centered on this axis.
If the width or height arguments are zero, it means the client should
decide its own window dimension.

The closed event is sent by the compositor when the surface will no
longer be shown. The output may have been destroyed or the user may
have asked for it to be removed. Further changes to the surface will be
ignored. The client should destroy the resource after receiving this
event, and create a new surface if they so choose.
