This is Cage, a Wayland kiosk. A kiosk runs a single, maximized
application.

This README is only relevant for development resources and instructions. For a
description of Cage and installation instructions for end-users, please see
[its project page](https://www.hjdskes.nl/projects/cage) and [the
Wiki](https://github.com/cage-kiosk/cage/wiki/).

## Release signatures

Releases up to version 0.1.4 are signed with [6EBC43B1](http://keys.gnupg.net/pks/lookup?op=vindex&fingerprint=on&search=0x37C445296EBC43B1). Releases from 0.1.5 onwards are signed with
[E88F5E48](https://keys.openpgp.org/search?q=34FF9526CFEF0E97A340E2E40FDE7BE0E88F5E48)
All releases are published on [GitHub](https://github.com/cage-kiosk/cage/releases).

## Building and running Cage

You can build Cage with the [meson](https://mesonbuild.com/) build system. It
requires wayland, wlroots, and xkbcommon to be installed. Optionally, install
scdoc for manual pages. Note that Cage is developed against the latest tag of
wlroots, in order to not constantly chase breaking changes as soon as they
occur.

Simply execute the following steps to build Cage:

```
$ meson build
$ ninja -C build
```

By default, this builds a debug build. To build a release build, use `meson
build --buildtype=release`.

Cage comes with compile-time support for XWayland. To enable this,
first make sure that your version of wlroots is compiled with this
option. Then, add `-Dxwayland=true` to the `meson` command above. Note
that you'll need to have the XWayland binary installed on your system
for this to work.

You can run Cage by running `./build/cage APPLICATION`. If you run it from
within an existing X11 or Wayland session, it will open in a virtual output as
a window in your existing session. If you run it at a TTY, it'll run with the
KMS+DRM backend. In debug mode (default build type with Meson), press
<kbd>Alt</kbd>+<kbd>Esc</kbd> to quit. For more configuration options, see
[Configuration](https://github.com/cage-kiosk/cage/wiki/Configuration).

Cage is based on the annotated source of tinywl and rootston.

# NAME

cage - a Wayland kiosk compositor

# SYNOPSIS

*cage* [-dhmrsv] [--] _application_ [application argument ...]

# DESCRIPTION

Cage runs a single, maximized application. Cage can run multiple applications,
but only a single one is visible at any point in time. User interaction and
activities outside the scope of the running application are prevented.

# OPTIONS

*-d*
	Don't draw client side decorations when possible.

*-h*
	Show the help message.

*-m* <mode>
	Set the multi-monitor behavior. Supported modes are:
	*last* Cage uses only the last connected monitor.
	*extend* Cage extends the display across all connected monitors.

*-s*
	Allow VT switching

*-v*
	Show the version number and exit.

# ENVIRONMENT

_DISPLAY_
	If compiled with Xwayland support, this will be set to the name of the
	X display used for Xwayland. Otherwise, probe the X11 backend.

_WAYLAND_DISPLAY_
	Specifies the name of the Wayland display that Cage is running on.

_XCURSOR_PATH_
	Directory where cursors are located.

_XCURSOR_SIZE_
	Specifies the configured cursor size.

_XCURSOR_THEME_
	Specifies the configured cursor theme.

_XKB_DEFAULT_RULES_, _XKB_DEFAULT_MODEL_, _XKB_DEFAULT_LAYOUT_,
_XKB_DEFAULT_VARIANT_, _XKB_DEFAULT_OPTIONS_
	Configures the xkb keyboard settings. See *xkeyboard-config*(7).
