# labwc
labwc is a wayland compositor based on wlroots
Aiming to become a light-weight openbox alternative for Wayland
## Dependencies
- wlroots
- wayland-protocols
## Background
I am looking for a Wayland compositor that feels like openbox, but haven't come across one yet. Playing around with some code-bases seems an obvious way to evaluate and explore options. I saw [sway](https://swaywm.org/), [cage](https://www.hjdskes.nl/blog/cage-01/) and [wio](https://wio-project.org/), and definitely like the feel of wlroots.
Before trying wlroots, I messed around with [QtWayland](https://github.com/qt/qtwayland), [grefsen](https://github.com/ec1oud/grefsen), [Mir](https://mir-server.io) / [egmde](https://github.com/AlanGriffiths/egmde). Lubuntu have [declared](https://lubuntu.me/lubuntu-development-newsletter-9/) that they will be switching to Wayland by default for 20.10 and that they are going to do this by porting Openbox to use the Mir display server and [Drew DeVaults](https://drewdevault.com/) QtLayerShell, etc.

## Running labwc
labwc can be run from a tty or in an existing Wayland/X11 session.
## Why?
I saw [sway](https://swaywm.org/), [cage](https://www.hjdskes.nl/blog/cage-01/) and [wio](https://wio-project.org/), and felt the itch to have a go at hacking on a wlroots compositor myself.
I am also quietly looking for a Wayland alternative to openbox and playing around with some code-bases seems an obvious way to evaluate and explore options.
<b>QtWayland and Mir</b>
Before trying wlroots, I messed around with [QtWayland](https://github.com/qt/qtwayland) / [grefsen](https://github.com/ec1oud/grefsen) and [Mir](https://mir-server.io) / [egmde](https://github.com/AlanGriffiths/egmde). These are pretty cool and still worth exploring further.
Lubuntu have [declared](https://lubuntu.me/lubuntu-development-newsletter-9/) that they will be switching to Wayland by default for 20.10 and that they are going to do this by porting Openbox to use the Mir display server and [Drew DeVaults](https://drewdevault.com/) QtLayerShell, etc. One to keep an eye on.
<b>kwin and mutter</b>
I don't think that the KDE and GNOME compositors will be right. Although they offer a brilliant experience, they are pretty heavy and quite integrated with their respective stacks. I think I'm right in saying that they're not standalone window managers.
[mutter](https://gitlab.gnome.org/GNOME/mutter) - 411k lines-of-code (LOC)
[kwin](https://github.com/KDE/kwin) - 191k LOC
In terms of size comparison of these two giants, it's worth reflecting on the size of a few friends:
[sway](https://github.com/swaywm/sway) - 37k LOC
[rootston]() - 7k LOC
[openbox](https://github.com/danakj/openbox) - 53k LOC
[i3](https://github.com/i3/i3) - 20k LOC (but does include i3bar, etc)
[dwm](https://dwm.suckless.org) - 2k LOC
