Phone compositor

wlroots based Phone compositor as used on the Librem5.

Phoc is pronounced like the English word fog.

Building Phoc

Dependencies

On a Debian based system run:

    sudo apt-get -y install build-essential
    sudo apt-get -y build-dep .

For an explicit list of dependencies check the Build-Depends entry in the debian/control file.

Building

We use the meson (and thereby Ninja) build system for phoc. The quickest way to get going is to do the following:

    meson setup _build
    meson compile -C _build
    meson install -C _build --skip-subprojects

This assumes you have wlroots installed on your system. If you don't have that and/or want to build from source run:

    meson -Dembed-wlroots=enabled --default-library=static _build
    meson compile -C _build

This will fetch a matching version of wlroots and build that as well.

Running

To run from the source tree use

    ./_build/run

Test

After making source changes run

    xvfb-run meson test -C _build

to see if anything broke.

Configuration

phoc's behaviour can be configured via GSettings. For your convienience, a set of scripts to manipulate config values is available in helpers directory.

• scale-to-fit toggles automatic scaling of applications that don't fit the screen. This setting is enabled per application using its reported app-id. For instance, to enable scaling of GNOME Maps windows use:

  ./helpers/scale-to-fit org.gnome.Maps on
  

• auto-maximize toggles automatic maximization of Wayland windows. Disabling it allows windows to be resized and moved, which may be desired when running phoc on desktop-like setups.

  ./helpers/auto-maximize off
  

Outputs are configured via phoc.ini config file - see src/phoc.ini.example for more information.

Debugging

phoc uses glib so the G_MESSAGES_DEBUG environment variable can be used to enable more log messages and G_DEBUG to assert on warnings and criticals. The log domains all start with phoc- and are usally phoc-<sourcefile>. All wlroots related messages are logged with phoc-wlroots. For more details on these environment variables, read the documentation for GLib.

There's also a PHOC_DEBUG enviroment variable to turn on some debugging features. Use PHOC_DEBUG=help phoc to see supported flags.
