When c->bw is 0, the right side of the MAX functions gets turned into an unsigned integer and that results in -1 being the outcome.
This causes big issues in xwayland clients.
this fixes another issue where the cursor doesn't change when selecting text
but there is still an issue about not changing border color of clients during
dnd operations
Bug: https://github.com/djpohly/dwl/issues/318
- allow user to use a different pkg-config binary
- restore almost all (and add other ones) warning flags (-Werror is not set)
- $(XWAYLAND) is added to our CPPFLAGS
- remove useless comments
- don't generate idle-protocol.h (not used)
it is closer to the suckless philosophy (foot implements things that the suckless
guys would say that should be done by tmux or something else, but I have no
desire to create a new terminal emulator, and the best fit is foot)
also alacritty uses +100Mb of memory, more that dwl itself (~90Mb)
and foot only ~20Mb
when using wlr_output_layout_move() wlroots internally
change the state of the output to manually configured and
when updating the layout these outputs aren't ignored by
wlroots, leaving us at our own
previously we tried to get a client from the surface and then compare it with
the excluded surface, if we cannot get a client from the surface (e.g: a layer
surface) it just ignored all the next idle inhibitors no matter what
What I have should done is just checking if the excluded surface is equal to
the current idle inhibitor's surface and continue in case it is.
this will help when sending to another monitor a fullscreen client
and also will prevent a crash when a client request fullscreen when it has no monitor
When the dwl executable is in use, cp fails without the -f flag.
POSIX defines this flag with:
> If a file descriptor for a destination file cannot be obtained,
> as described in step 3.a.ii., attempt to unlink the destination
> file and proceed.
dwl.c: In function ‘unmaplayersurface’:
dwl.c:2253:9: error: suggest parentheses around assignment used as truth value [-Werror=parentheses]
2253 | layersurface->layer_surface->mapped = layersurface->mapped = 0;
| ^~~~~~~~~~~~
cc1: all warnings being treated as errors
make: *** [<builtin>: dwl.o] Error 1
clang not affected
Initializing it to an empty string had broken configuring xkbcommon
through the environment (XKB_DEFAULT_OPTIONS).
Fixes: ae31391115 ("initialize rules and xkb_rules")
now client_surface()->data is a pointer to the wlr_scene_tree of clients
which allows us to not call wlr_scene_node_lower_to_bottom() for every clients
Check the wlr_layer_surface_v1_state.committed bitmask to see if we need
to rearrange. This is also what sway does.
Without this check, every commit request (even if only the attached buffer
changed) will lead to another configure event, which will lead to another
commit, etc.
This loop results in swaybg consuming 100% CPU.

On SIGCHLD, check to make sure the terminated process is not the
XWayland process before reaping it, allowing wlroots to waitpid() for it
successfully.

dwl is a compact, hackable compositor for Wayland based on [wlroots](https://gitlab.freedesktop.org/wlroots/wlroots/). It is intended to fill the same space in the Wayland world that dwm does in X11, primarily in terms of philosophy, and secondarily in terms of functionality. Like dwm, dwl is:

- Configurable multi-monitor layout support, including position and rotation
- Configurable HiDPI/multi-DPI support
- Idle-inhibit protocol which lets applications such as mpv disable idle
monitoring
- Provide information to external status bars via stdout/stdin
- Urgency hints via xdg-activate protocol
- Support screen lockers via input-inhibitor protocol
- Various Wayland protocols
- XWayland support as provided by wlroots (can be enabled in `config.mk`)
- Zero flickering - Wayland users naturally expect that "every frame is perfect"

Feature *non-goals* for the main codebase include:

- Animations and visual effects
## Building dwl
dwl has only two dependencies: wlroots and wayland-protocols. Simply install these (and their `-devel` versions if your distro has separate development packages) and run `make`. If you wish to build against a Git version of wlroots, check out the [wlroots-next branch](https://github.com/djpohly/dwl/tree/wlroots-next).

To enable XWayland, you should also install xorg-xwayland and uncomment its flag in `config.mk`.

## Configuration
All configuration is done by editing `config.h` and recompiling, in the same manner as dwm. There is no way to separately restart the window manager in Wayland without restarting the entire display server, so any changes will take effect the next time dwl is executed.

## Running dwl
dwl can be run on any of the backends supported by wlroots. This means you can run it as a separate window inside either an X11 or Wayland session, as well as directly from a VT console. Depending on your distro's setup, you may need to add your user to the `video` and `input` groups before you can run dwl on a VT.

to add your user to the `video` and `input` groups before you can run dwl on
a VT. If you are using `elogind` or `systemd-logind` you need to install
polkit; otherwise you need to add yourself in the `seat` group and
enable/start the seatd daemon.
When dwl is run with no arguments, it will launch the server and begin handling any shortcuts configured in `config.h`. There is no status bar or other decoration initially; these are instead clients that can be run within the Wayland session.

If you would like to run a script or command automatically at startup, you can specify the command using the `-s` option. This command will be executed as a shell command using `/bin/sh -c`. It serves a similar function to `.xinitrc`, but differs in that the display server will not shut down when this process terminates. Instead, dwl will send this process a SIGTERM at shutdown and wait for it to terminate (if it hasn't already). This makes it ideal for execing into a user service manager like [s6](https://skarnet.org/software/s6/), [anopa](https://jjacky.com/anopa/), [runit](http://smarden.org/runit/faq.html#userservices), or [`systemd --user`](https://wiki.archlinux.org/title/Systemd/User).

Note: The `-s` command is run as a *child process* of dwl, which means that it does not have the ability to affect the environment of dwl or of any processes that it spawns. If you need to set environment variables that affect the entire dwl session, these must be set prior to running dwl. For example, Wayland requires a valid `XDG_RUNTIME_DIR`, which is usually set up by a session manager such as `elogind` or `systemd-logind`. If your system doesn't do this automatically, you will need to configure it prior to launching `dwl`, e.g.:

### Status information
Information about selected layouts, current window title, and selected/occupied/urgent tags is written to the stdin of the `-s` command (see the `printstatus()` function for details). This information can be used to populate an external status bar with a script that parses the information. Failing to read this information will cause dwl to block, so if you do want to run a startup command that does not consume the status information, you can close standard input with the `<&-` shell redirection, for example:
