The unfettered keyboard is an on-screen keyboard designed for Linux mobile. It
uses the concept of Julow's [Unexpected Keyboard](https://github.com/Julow/Unexpected-Keyboard),
where swiping on a displayed key cap produces a different key press. For
example, swiping up and right on the "q" key generates a "1" keypress. This
makes it possible for many keys to be available on the same keyboard layout.
# Dependencies
The dependencies are:
- [expat](https://github.com/libexpat/libexpat) - 🌿 Fast streaming XML parser written in C99 with >90% test coverage
- [fcft](https://codeberg.org/dnkl/fcft) - A simple library for font loading and glyph rasterization using FontConfig, FreeType and pixman.
- [meson](https://github.com/mesonbuild/meson) - The Meson Build System
- [pixman](https://gitlab.freedesktop.org/pixman/pixman) - Image processing and manipulation library
- [wayland](https//gitlab.freedesktop.org/wayland/wayland) - Core Wayland window system code and protocol
- [xkbcommon](https://github.com/xkbcommon/libxkbcommon) - keymap handling library for toolkits and window systems
Additionally, fonts are needed to render the following Unicode, non-ASCII symbols:
- ← (U+2190)
- ↑ (U+2191)
- → (U+2192)
- ↓ (U+2193)
- ⇧ (U+21E7)
- ⌦ (U+2326)
- ⌫ (U+232B)
- ⏎ (U+23CE)
- ⭾ (U+2B7E)
# Usage
This keyboard is designed to work, but it is not designed to be used. Using it
is awkward:
$ meson setup build
$ ninja -C build
$ curl -L -o /tmp/bottom_row.xml https://github.com/Julow/Unexpected-Keyboard/raw/master/res/xml/bottom_row.xml
$ curl -L -o /tmp/latn_qwerty_us.xml https://github.com/Julow/Unexpected-Keyboard/raw/master/srcs/layouts/latn_qwerty_us.xml
$ sudo mkdir /usr/share/unfettered-keyboard/layouts
$ sudo cp /tmp/bottom_row.xml /tmp/latn_qwerty_us.xml /usr/share/unfettered-keyboard/layouts
$ build/ufkbd

* @page page_fractional_scale_v1 The fractional_scale_v1 protocol
* Protocol for requesting fractional surface scales
*
* @section page_desc_fractional_scale_v1 Description
*
* This protocol allows a compositor to suggest for surfaces to render at
* fractional scales.
*
* A client can submit scaled content by utilizing wp_viewport. This is done by
* creating a wp_viewport object for the surface and setting the destination
* rectangle to the surface size before the scale factor is applied.
*
* The buffer size is calculated by multiplying the surface size by the
* intended scale.
*
* The wl_surface buffer scale should remain set to 1.
*
* If a surface has a surface-local size of 100 px by 50 px and wishes to
* submit buffers with a scale of 1.5, then a buffer of 150px by 75 px should
* be used and the wp_viewport destination rectangle should be 100 px by 50 px.
*
* For toplevel surfaces, the size is rounded halfway away from zero. The
* rounding algorithm for subsurface position and size is not defined.

*
* @section page_desc_input_method_unstable_v2 Description
*
* This protocol allows applications to act as input methods for compositors.
*
* An input method context is used to manage the state of the input method.
*
* Text strings are UTF-8 encoded, their indices and lengths are in bytes.
*
* This document adheres to the RFC 2119 when using words like "must",
* "should", "may", etc.
*
* Warning! The protocol described in this file is experimental and
* backward incompatible changes may be made. Backward compatible changes
* may be added together with the corresponding interface version bump.
* Backward incompatible changes are done by bumping the version number in
* the protocol and interface names and resetting the interface version.
* Once the protocol is to be declared stable, the 'z' prefix and the
* version number in the protocol and interface names are removed and the
* interface version number is reset.

* @section page_iface_wp_viewport_desc Description
*
* An additional interface to a wl_surface object, which allows the
* client to specify the cropping and scaling of the surface
* contents.
*
* This interface works with two concepts: the source rectangle (src_x,
* src_y, src_width, src_height), and the destination size (dst_width,
* dst_height). The contents of the source rectangle are scaled to the
* destination size, and content outside the source rectangle is ignored.
* This state is double-buffered, and is applied on the next
* wl_surface.commit.
*
* The two parts of crop and scale state are independent: the source
* rectangle, and the destination size. Initially both are unset, that
* is, no scaling is applied. The whole of the current wl_buffer is
* used as the source, and the surface size is as defined in
* wl_surface.attach.
*
* If the destination size is set, it causes the surface size to become
* dst_width, dst_height. The source (rectangle) is scaled to exactly
* this size. This overrides whatever the attached wl_buffer size is,
* unless the wl_buffer is NULL. If the wl_buffer is NULL, the surface
* has no content and therefore no size. Otherwise, the size is always
* at least 1x1 in surface local coordinates.
*
* If the source rectangle is set, it defines what area of the wl_buffer is
* taken as the source. If the source rectangle is set and the destination
* size is not set, then src_width and src_height must be integers, and the
* surface size becomes the source rectangle size. This results in cropping
* without scaling. If src_width or src_height are not integers and
* destination size is not set, the bad_size protocol error is raised when
* the surface state is applied.
*
* The coordinate transformations from buffer pixel coordinates up to
* the surface-local coordinates happen in the following order:
* 1. buffer_transform (wl_surface.set_buffer_transform)
* 2. buffer_scale (wl_surface.set_buffer_scale)
* 3. crop and scale (wp_viewport.set*)
* This means, that the source rectangle coordinates of crop and scale
* are given in the coordinates after the buffer transform and scale,
* i.e. in the coordinates that would be the surface-local coordinates
* if the crop and scale was not applied.
*
* If src_x or src_y are negative, the bad_value protocol error is raised.
* Otherwise, if the source rectangle is partially or completely outside of
* the non-NULL wl_buffer, then the out_of_buffer protocol error is raised
* when the surface state is applied. A NULL wl_buffer does not raise the
* out_of_buffer error.
*
* If the wl_surface associated with the wp_viewport is destroyed,
* all wp_viewport requests except 'destroy' raise the protocol error
* no_surface.
*
* If the wp_viewport object is destroyed, the crop and scale
* state is removed from the wl_surface. The change will be applied
* on the next wl_surface.commit.

<interface name="zwlr_layer_shell_v1" version="4">
<description summary="create surfaces that are layers of the desktop">
Clients can use this interface to assign the surface_layer role to
wl_surfaces. Such surfaces are assigned to a "layer" of the output and
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
many desktop shell components, and a broad number of other applications
that interact with the desktop.
</description>
<request name="get_layer_surface">
<description summary="create a layer_surface from a surface">
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.
Clients can specify a namespace that defines the purpose of the layer
surface.

These values indicate which layers a surface can be rendered in. They
are ordered by z depth, bottom-most first. Traditional shell surfaces
will typically be rendered between the bottom and top layers.
Fullscreen shell surfaces are typically rendered at the top layer.
Multiple surfaces can share a single layer, and ordering within a
single layer is undefined.

object any more. Objects that have been created through this instance
are not affected.
</description>

</interface>
<interface name="zwlr_layer_surface_v1" version="4">
<description summary="layer metadata interface">
An interface that may be implemented by a wl_surface, for surfaces that
are designed to be rendered as a layer of a stacked desktop-like
environment.
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.
The client can re-map the surface by performing a commit without any
buffer attached, waiting for a configure event and handling it as usual.
</description>
<request name="set_size">
<description summary="sets the size of the surface">
Sets the size of the surface in surface-local coordinates. The
compositor will display the surface centered with respect to its
anchors.
If you pass 0 for either value, the compositor will assign it and
inform you of the assignment in the configure event. You must set your
anchor to opposite edges in the dimensions you omit; not doing so is a
protocol error. Both values are 0 by default.
Size is double-buffered, see wl_surface.commit.

<description summary="configures the anchor point of the surface">
Requests that the compositor anchor the surface to the specified edges
and corners. If two orthogonal edges are specified (e.g. 'top' and
'left'), then the anchor point will be the intersection of the edges
(e.g. the top left corner of the output); otherwise the anchor point
will be centered on that edge, or in the center if none is specified.
Anchor is double-buffered, see wl_surface.commit.

<arg name="anchor" type="uint" enum="anchor"/>
</request>
<request name="set_exclusive_zone">
<description summary="configures the exclusive geometry of this surface">
Requests that the compositor avoids occluding an area with other
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.
The default value is 0.
Exclusive zone is double-buffered, see wl_surface.commit.

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.

<description summary="types of keyboard interaction possible for a layer shell surface">
Types of keyboard interaction possible for layer shell surfaces. The
rationale for this is twofold: (1) some applications are not interested
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.
</description>
<entry name="none" value="0">
<description summary="no keyboard focus is possible">
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.
</description>
</entry>
<entry name="exclusive" value="1">
<description summary="request exclusive keyboard focus">
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.
</description>
</entry>
<entry name="on_demand" value="2" since="4">
<description summary="request regular keyboard focus semantics">
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.

</enum>
<request name="set_keyboard_interactivity">
<description summary="requests keyboard events">
Set how keyboard events are delivered to this surface. By default,
layer shell surfaces do not receive keyboard events; this request can
be used to change this.
This setting is inherited by child surfaces set by the get_popup
request.
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.
Keyboard interactivity is double-buffered, see wl_surface.commit.

<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.

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.
