# How to Contribute

1. Report bugs as github issues. We don't use a template, but try to provide
   some sensible information such as what happened, what you expected to happen
   and steps to reproduce. If applicable try with default configuration.  If
   you are able to, try to do some debugging (guidelines below).

2. Submit patches as github pull-requests. If you wish to introduces significant
   changes or new features, consult the [scope document], discuss on IRC or via
   a github issue first.

# Debugging

There is no one-way-fits-all method for debugging, so you have to use your
antennae and do some detective work.

This section contains some approachies which may prove useful.

If the compositor crashes, a good starting point is to produce a backtrace by
building with ASAN/UBSAN:

```
meson -Db_sanitize=address,undefined build/
ninja -C build/
```

Get debug log with `labwc -d`. The log can be directed to a file with `labwc -d
2>log.txt`

To see what is happening on the wayland protocol for a specific client, run it
with environment variable `WAYLAND_DEBUG` set to 1, for example `WAYLAND_DEBUG=1
foot`.

To see what the compositor is doing on the protocol run `labwc` nested (i.e.
start labwc from a terminal in another instance of labwc or some other
compositor) with `WAYLAND_DEBUG=server`. This filters out anything from clients.

For wayland clients, you can get a live view of some useful info using [wlhax].

If you think you've got a damage issue, you can run labwc like this:
`WLR_SCENE_DEBUG_DAMAGE=highlight labwc` to get a visual indication of damage
regions.

To emulate multiple outputs (even if you only have one physical monitor), run
with `WLR_WL_OUTPUTS=2 labwc` or similar. See [`wlroots/docs/env_vars.md`] for
more options.

For some types of bugs, it might be useful to find out which mesa driver (.so)
you are using. This can be done with `EGL_LOG_LEVEL=debug labwc 2>&1 | grep
MESA-LOADER`

To rule out driver issues you can run with `WLR_RENDERER=pixman labwc`

You can also get some useful system info with [drm_info].

Use `sudo libinput debug-events` to show input events.

From a terminal you can use `xev -event keyboard` and `wev -f wl_keyboard:key`
to analyse keyboard events

# Packaging

Some distributions carry labwc in their repositories or user repositories.

- @ptrcnull (Alpine)
- @narrat (Arch)
- @jbeich (FreeBSD)
- @adcdam (Slackware)

kindly maintain the packages in their respective distro.

Let's keep them informed of new releases and any changes that relate to
packaging.  If you are maintaining a labwc package for another distro feel free
to open an issue so we can add you to this list.

# Coding Style

labwc is written in the [Linux kernel coding style] with a small number of
deviations to align with [Drew Devault's preferred coding style] nameley:

1. [Function Declaration](https://git.sr.ht/~sircmpwn/cstyle#function-declarations)
2. [Braces for one-line statement](https://git.sr.ht/~sircmpwn/cstyle#brace-placement)
3. [Organisation of header #include statements](https://git.sr.ht/~sircmpwn/cstyle#header-files)
4. [Breaking of long lines](https://git.sr.ht/~sircmpwn/cstyle#splitting-long-lines)

The reasons for specifying a style is not that we enjoy creating rules, but
because it makes reading/maintaining the code and spotting problems much easier.

If you are new to this style and want to get going quickly, either just imitate
the style around you, or read the summary below and use `./scripts/check` to run
some formatting checks.

## Linux Kernel Style Basics

The preferred line length limit is 80 columns, although this is a bit soft.

Tabs are 8 columns wide. Identation with spaces is not used.

Opening braces go on the same line, except for function definitions.

Put `*` with the identifier when defining pointers, for example `char *foo`

Spaces are placed around binary operators but not unary, like this:

```
int x = y * (2 + z);
foo(--a, -b);
```

`sizeof(*foo)` is preferred over `sizeof(struct foo)`

Use `if (!p)` instead of `if (p == 0)` or `if (p == NULL)`

Comments are written as follows:

```
/* This is a single-line comment */

/*
 * This is a multi-line comment which is much much much much much much
 * longer.
 */
```

When documenting functions in header files we use the [kernel-doc format]:

```
/**
 * function_name() - Brief description of function.
 * @arg1: Describe the first argument.
 * @arg2: Describe the second argument.
 *        One can provide multiple line descriptions
 *        for arguments.
 *
 * A longer description, with more discussion of the function function_name()
 * that might be useful to those using or modifying it. Begins with an
 * empty comment line, and may include additional embedded empty
 * comment lines.
 *
 * The longer description may have multiple paragraphs.
 *
 * Return: Describe the return value of function_name.
 *
 * The return value description can also have multiple paragraphs, and should
 * be placed at the end of the comment block.
 */
```

## Devault Deviations

Functions are defined as below with `name` on a new line:

```
return type
name(parameters...)
{
	body
}
```

Braces are mandatory even for one-line statements.

```
if (cond) {
	...
}
```

`#include` statements at the top of the file are organized by locality (`<>`
first, then `""`), then alphabetized.

When breaking a statement onto several lines, indent the subsequent lines once.
If the statement declares a `{}` block, indent twice instead. Also, place
operators (for example `&&`) on the next line.

```
	if (seat->pressed.surface && ctx->surface != seat->pressed.surface
			&& !update_pressed_surface(seat, ctx)
			&& !seat->drag_icon) {
		if (cursor_has_moved) {
			process_cursor_motion_out_of_surface(server, time_msec);
		}
		return;
	}
```

## Labwc Specifics

### API

We have a very small, modest API and encourage you to use it.

1. `znew()` - as a shorthand for calloc(1, sizeof()) with type checking
   [common/mem.h]

2. `zfree()` to zero after free - [common/mem.h]

3. `wl_list_append()` to add elements at end of lists - [common/list.h]

### The Use of glib

We try to keep the use of glib pretty minimal for the following reasons:

- The use of glib has been known to make AddressSanitiser diagnose false
  positives and negatives.
- Log messages coming from glib functions look inconsistent.
- The use of glib functions, naming-conventions and iterators in a code base
  that is predominantly ANSI C creates a clash which makes readability and
  maintainability harder.
- Mixing gmalloc()/malloc() and respective free()s can create problems with
  memory pools [^1]

Having said that, with our use of cairo and pango we depend on glib-2.0 anyway
so linking with it and making use of some of its helper functions comes for free
and can keep the code simpler.

For example, if we were going to carry out extensive string manipulation,
GString and utf8 helpers would be okay. Some functions such as
`g_utf8_casefold()` would be pretty hard to write from scratch and are fine to
use. Having said that, labwc does not do much string-mangling.

The following functions are used today and are deemed acceptable by the core
devs:

- `g_shell_parse_argv()`
- `g_strsplit()`
- `g_pattern_match_simple()`

When using these types of functions it is often desirable to support with some
glib code, which is okay provided it is kept local and self-contained. See
example from `src/theme.c`:

```
static bool
match(const gchar *pattern, const gchar *string)
{
	GString *p = g_string_new(pattern);
	g_string_ascii_down(p);
	bool ret = (bool)g_pattern_match_simple(p->str, string);
	g_string_free(p, true);
	return ret;
}
```

### The use of GNU extensions

We avoid [GNU C extensions] because we want to fit into the eco-system
(wayland and wlroots) we live in.

We do use `__typeof__` which strictly speaking is a GNU C extension (`typeof`)
but through the use of `__` is supported by gcc and clang without defining
`_GNU_SOURCE`. The justification for this is that Wayland uses it, for example
in the [`wl_container_of()`] macro which is needed in `wl_list*` and it
does provide pretty big benefits in terms of type safety.

We compile with `-std=c11` because that's what 'wlroots' uses and we do not
want to increase the entry-level for OSs without good reason (and currently
we can't think of one).

### Naming Conventions

There are three types of coordinate systems: surface, output and layout - for
which the variables (sx, sy), (ox, oy) and (lx, ly) are used respectively in
line with wlroots.

With the introduction of the scene-graph API, some wlroots functions also use
node coordinates (nx, ny) but we prefer (sx, sy) where possible.

We do not worry about namespace issues too much and we try to not make the code
a pain to use just to uniquify names. If we were writing a library we would
prefix public functions and structs with `lab_`, but we are not. We do however
prefix public function names with the filename of the translation unit.  For
example, public functions in `view.c` begin with `view_`.

We do start enums with `LAB_`

We use the prefix `handle_` for signal-handler-functions in order to be
consistent with sway and rootston. For example
`view->request_resize.notify = handle_request_resize`

# Commit Messages

The log messages that explain changes are just as important as the changes
themselves. Try to describe the 'why' to help future developers.

Write [commit messages] like so, keeping the top line to this sort of syntax:

```
cursor: add special feature
```

This first line should:

- Be a short description
- In most cases be prefixed with "area: " where area refers to a filename
  or identifier for the general area of the code being modified.
- Not capitalize the first word following the "area: " prefix, unless
  it's a name, acronym or similar.
- Skip the full stop

And please wrap the commit message at max 74 characters, otherwise `git log`
and similar look so weird. URLs and other references are exempt.

# Submitting patches

Base both bugfixes and new features on `master`.

# Native Language Support

Translators can add their `MY_LOCALE.po` files to the `po` directory
based on `po/labwc.pot` and issue a pull request. For example:

```
xgettext --keyword=_ --language=C --add-comments -o po/labwc.pot src/menu/menu.c
```

                       Version 2, June 1991

Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.

Preamble

The licenses for most software are designed to take away your
freedom to share and change it.  By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users.  This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it.  (Some other Free Software Foundation software is covered by
the GNU Lesser General Public License instead.)  You can apply it to
your programs, too.

When we speak of free software, we are referring to freedom, not
price.  Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.

To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.

For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have.  You must make sure that they, too, receive or can get the
source code.  And you must show them these terms so they know their
rights.

We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.

Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software.  If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.

Finally, any free program is threatened constantly by software
patents.  We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary.  To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.

The precise terms and conditions for copying, distribution and
modification follow.

GNU GENERAL PUBLIC LICENSE
   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License.  The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language.  (Hereinafter, translation is included without limitation in
the term "modification".)  Each licensee is addressed as "you".

Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope.  The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.

1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.

You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.

2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:

a) You must cause the modified files to carry prominent notices
    stating that you changed the files and the date of any change.

b) You must cause any work that you distribute or publish, that in
    whole or in part contains or is derived from the Program or any
    part thereof, to be licensed as a whole at no charge to all third
    parties under the terms of this License.

c) If the modified program normally reads commands interactively
    when run, you must cause it, when started running for such
    interactive use in the most ordinary way, to print or display an
    announcement including an appropriate copyright notice and a
    notice that there is no warranty (or else, saying that you provide
    a warranty) and that users may redistribute the program under
    these conditions, and telling the user how to view a copy of this
    License.  (Exception: if the Program itself is interactive but
    does not normally print such an announcement, your work based on
    the Program is not required to print an announcement.)

These requirements apply to the modified work as a whole.  If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works.  But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.

Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.

In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.

3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:

a) Accompany it with the complete corresponding machine-readable
    source code, which must be distributed under the terms of Sections
    1 and 2 above on a medium customarily used for software interchange; or,

b) Accompany it with a written offer, valid for at least three
    years, to give any third party, for a charge no more than your
    cost of physically performing source distribution, a complete
    machine-readable copy of the corresponding source code, to be
    distributed under the terms of Sections 1 and 2 above on a medium
    customarily used for software interchange; or,

c) Accompany it with the information you received as to the offer
    to distribute corresponding source code.  (This alternative is
    allowed only for noncommercial distribution and only if you
    received the program in object code or executable form with such
    an offer, in accord with Subsection b above.)

The source code for a work means the preferred form of the work for
making modifications to it.  For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable.  However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.

If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.

4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License.  Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.

5. You are not required to accept this License, since you have not
signed it.  However, nothing else grants you permission to modify or
distribute the Program or its derivative works.  These actions are
prohibited by law if you do not accept this License.  Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.

6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions.  You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.

7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License.  If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all.  For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.

If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.

It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices.  Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.

This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.

8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded.  In such case, this License incorporates
the limitation as if written in the body of this License.

9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time.  Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.

Each version is given a distinguishing version number.  If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation.  If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.

10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission.  For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this.  Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.

NO WARRANTY

11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.

12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.

END OF TERMS AND CONDITIONS

How to Apply These Terms to Your New Programs

If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.

To do so, attach the following notices to the program.  It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.

<one line to give the program's name and a brief idea of what it does.>
 Copyright (C) <year> <name of author>

This program is free software; you can redistribute it and/or modify
    it under the terms of the GNU General Public License as published by
    the Free Software Foundation; either version 2 of the License, or
    (at your option) any later version.

This program is distributed in the hope that it will be useful,
    but WITHOUT ANY WARRANTY; without even the implied warranty of
    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
    GNU General Public License for more details.

You should have received a copy of the GNU General Public License along
    with this program; if not, write to the Free Software Foundation, Inc.,
    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

Also add information on how to contact you by electronic and paper mail.

If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:

Gnomovision version 69, Copyright (C) year name of author
    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
    This is free software, and you are welcome to redistribute it
    under certain conditions; type `show c' for details.

The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License.  Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.

You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary.  Here is a sample; alter the names:

Yoyodyne, Inc., hereby disclaims all copyright interest in the program
  `Gnomovision' (which makes passes at compilers) written by James Hacker.

<signature of Ty Coon>, 1 April 1989
 Ty Coon, President of Vice

This General Public License does not permit incorporating your program into
proprietary programs.  If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library.  If this is what you want to do, use the GNU Lesser General
Public License instead of this License.

## 0.6.0 - 2022-11-17

This release contains significant refactoring to use the wlroots
scene-graph API. This touches many areas of the code, particularly
rendering, server-side-decoration, the layer-shell implementation and the
menu. Many thanks to @Consolatis for doing most of the heavy lifting with
this.

Noteworthy, related changes include:

- The use of a buffer implementation instead of using wlr_texture. It
  handles both images and fonts, and scales according to output scale.
- The use of node-descriptors to assign roles to wlr_scene_nodes in order
  to simplify the code.
- Improving the "Debug" action to print scene-graph trees

A large number of bugs and regressions have been fixed following the
re-factoring, too many to list here, but we are grateful to all who have
reported, tested and fixed issues. Particular mentions go to @bi4k8,
@flrian, @heroin-moose, @jlindgren90, @Joshua-Ashton, @01micko and @skerit

### Added

- Set environment variable LABWC_PID to the pid of the compositor so that
 SIGHUP and SIGTERM can be sent to specific instances.
- Add command line options --exit and --reconfigure.
- Support setting keyboard repeat and delay at runtime. Written-by: @bi4k8
- Add support for mouse-wheel bindings. Set default bindings to switch
 workspaces when scrolling on the desktop. Written-by: @Arnaudv6
- Implement key repeat for keybindings. Written-by: @jlindgren90
- Support smooth scroll and horizontal scroll. Written-by: @bi4k8
- Implement virtual keyboard and pointer protocols, enabling the use of
 clients such as wtype and wayvnc. Written-by: @Joshua-Ashton
- Add github workflow CI including Debian, FreeBSD, Arch and Void,
 including a build without xwayland.
- Support keybind "None" action to clear other actions for a particular
 keybind context. Written-by: @jlindgren90
- Support font slant (itliacs) and weight (bold). Written-by: @jlindgren90
- Support `<default />` mousebinds to load default mousebinds and provide
 a way to keep config files simpler whilst allowing user specific binds.
 Issue #416. Written-by: @Consolatis
- Add config option `<core><cycleViewOutlines>` to enable/disable preview
 of outlines. Written-by: @Flrian
- Render submenu arrows
- Allow highest level menu definitions - typically used for root-menu and
 client-menu - to be defined without label attritube, for example like this:
 `<openbox_menu><menu id="root-menu">...</menu></openbox>`. Issue #472
- Allow xdg-desktop-portal-wlr to work out of the box by initializing dbus
 and systemd activation environment. This enables for example OBS Studio
 to work with no user configuration. If systemd or dbus is not available
 the environment update will fail gracefully. PR #461
 Written-by: @Joshua-Ashton and @Consolatis
- Workspaces. Written-by: @Consolatis
- presentation-time protocol
- Native language support for client-menus. Written-by: @01micko
- Touch support. Written-by: @bi4k8
- drm_lease_v1 for VR to work and leasing of desktop displays.
 Written-by: Joshua Ashton
- ToggleAlwaysOnTop action. Written-by: @Consolatis
- Command line option -C to specify config directory
- Theme options osd.border.color and osd.border.width. Written-by: @Consolatis
- Menu `<separator />` and associated theme options:
 menu.separator.width, menu.separator.padding.width,
 menu.separator.padding.height and menu.separator.color
- Adjust maximized and tiled windows according to usable_area taking
 into account exclusive layer-shell clients. Written-by: @Consolatis
- Restore natural geometry when moving tiled/maximized window
 Fixes #391. Written-by: @Consolatis
- Improve action implementation to take a list of arguments in preperation
 for actions with multiple arguments. Written-by: @Consolatis

### Fixed

- Remove unwanted gap when initially (on map) positioning windows larger
 than output usable area (issue #403).
- Prevent setting cursor icon on drag. Written-by: @Consolatis (issue #549)
- Fix bugs relating to sending matching pairs of press and release
 keycodes to clients when using keybinds. Also fix related key-repeat
 bug. (Issue #510)
- Fix wlr_output_cursor initialization bug on new output.
 Written-by: @jlindgren90
- Show correct cursor for resize action triggered by keybind.
 Written-by: @jlindgren
- Fix bug which manifest itself when keeping button pressed in GTK3 menu
 and firefox context menu. Written-by: @jlindgren90
- Enable tap be default on non-touch devices (which some laptop trackpads
 apparently are)
- Handle missing cursor theme (issue #246). Written-by: @Consolatis
- Fix various surface syncronization, stacking, positioning and focus
 issues, including those related to both xwayland, scroll/drag events
 and also #526 #483
- On first map, do not center xwayland views with explicitly specified
 position. Written-by: @jlindgren90

- Fix various bugs associated with destroying/disabling outputs, including
 issue #497
- Hide Alt-Tab switcher when canceling via Escape. @jlindgren90
- (Re)set seat when xwayland is ready (because wlroots reset the seat
 assigned to xwayland to NULL whenever Xwayland terminates).
 Issues #166 #444. Written-by: @Consolatis. Helped-by: @droc12345
- Increase File Descriptor (FD) limit to max because a compositor has to
 handle many: client connections, DMA-BUFs, wl_data_device pipes and so on.
 Fixes client freeze/crashes (swaywm/sway#6642). Written-by: @Joshua-Ashton
- Fix crash when creating a cursor constraint and there is no currently
 focused view.
- Gracefully handle dying client during interactive move.
 Written-by: @Consolatis
- Dynamically adjust server-side-deccoration invisible resize areas based
 on usable_area to ensure that cursor events are sent to clients such as
 panels in preference to grabbing window edges. Fixes #265.
 Written-by: @Consolatis
- Always position submenus inside output extents. Fixes #276
 Written-by: @Consolatis
- Do not crash when changing TTY. Written-by: @bi4k8
- Set wlroots.wrap to a specific commit rather than master because it
 enables labwc commits to be checked out and build without manually
 having to find the right wlroots commit if there are upstream breaking
 changes.
- Increase accuracy of window center-alignment, taking into account
 usable_area and window decoration. Also, top/left align if window is
 bigger than usable area.
- Handle view-destruction during alt-tab cycling.
 Written-by: @Joshua-Ashton
- Survive all outputs being disabled
- Check that double-clicks are on the same window. Written-by: yizixiao
- Set xdg-shell window position before maximize on first map so that the
 unmaximized geometry is known when started in maximized mode.
 Fixes issue #305. Reported-by: @01micko
- Support `<menu><item><action name="Execute"><execute>`
 `<exectue>` is a deprecated name for `<command>`, but is supported for
 backward compatibility with old menu-generators.
- Keep xwayland-shell SSD state on unmap/map cycle.
 Written-by: @Consolatis
- Prevent segfault on missing direction arguments. Reported-by: @flrian
- Fix keybind insertion order to restore intended behavior of keybinds
 set by `<default />`. Written-by: @Consolatis
- Ensure client-menu actions are always applied on window they belong to
 This fixes #380. Written-by: @Consolatis
- Keep window margin in sync when toggling decorations.
 Written-by: @Consolatis
- Fix handling of client-initiated configure requests.
 Written-by: @jlindgren90
- Always react to new output configuration. Reported-by @heroin-moose and
 Written-by: @Consolatis
- Fix bug in environment variable expansion by allowing underscores to be
 part of the variable names. Issue #439
- Fix parsing bug of adaptiveSync setting and test for support

### Changed

- src/config/rcxml.c: distinguish between no and unknown font places so
 that `` with no `place` attribute can be added after other font
 elements without over-writing their values. Written-by: @bi4k8
- theme: change window.label.text.justify default to center
- Redefine the SSD "Title" context to cover the whole Titlebar area except
 the parts occupied by buttons. This allows "Drag" and "DoubleClick"
 actions to be de-coupled from buttons. As a result, "Drag" and
 "DoubleClick" actions previously defined against "TitleBar" should now
 come under the "Title" context, for example:
 `<mousebind button="Left" action="Drag"><action name="Move"/></mousebind>`
- Remove default alt-escape keybind for Exit because too many people have
 exited the compositor by mistake trying to get out of alt-tab cycling
 or similar.

## [0.5.3] - 2022-07-15

### Added

- wlr-output-power-management protocol to enable clients such as wlopm
  Written-by: @bi4k8

### Fixed

- Call foreign-toplevel-destroy when unmapping xwayland surfaces because
  some xwayland clients leave unmapped child views around. Although
  handle_destroy() is not called for these, we have to call
  foreign-toplevel-destroy to avoid clients such as panels incorrecly
  showing them.
- Handle xwayland set_override_redirect events to fix weird behaviour with
  gitk menus and rofi.
- Re-focus parent surface on unmapping xwayland unmanaged surfaces
  Fixes #352 relating to JetBrains and Intellij focus issues
  Written-by: Jelle De Loecker
- Do not segfault on missing drag icon. Written-by: @Consolatis
- Fix windows irratically sticking to edges during move/resize.
  Fixes issues #331 and #309

## [0.5.2] - 2022-05-17

This is a minor bugfix release mostly to ease packaging.

### Fixed

- Properly use system provided wlroots. Written-by: @eli-schwartz

## [0.5.1] - 2022-04-08

### Added

- Honour size increments from WM_SIZE_HINTS, for example to allow
  xwayland terminal emulators to be resized to a width/height evenly
  divisible by the cell size. Written-by: @jlindgren90
- Implement cursor input for overlay popups. Written-by: @Consolatis

### Fixed

- Do not raise xwayland windows when deactivating (issue #270).
  Written-by: @Consolatis
- Restore drag mouse-bindings and proper double-click (issues #258 and
  #259). Written-by: @Consolatis
- Implement cursor input for unmanaged xwayland surfaces outside their
  parent view. Without this menus extending outside the main application
  window do not receive mouse input. Written-by: @jlindgren90
- Allow dragging scrollbar or selecting text even when moving cursor
  outside of the window (issue #241). Written-by: @Consolatis
- Fix positioning of xwayland views with multiple queued configure
  events. Written-by: @Consolatis
- Force a pointer enter event on the surface below the cursor when
  cycling views (issue #162). Written-by: @Consolatis
- Fix qt application crash on touchpad scroll (issue #225).
  Written-by: @Consolatis

## [0.5.0] - 2022-02-18

As usual, this release contains a bunch of fixes and improvements, of
which the most notable feature-type changes are listed below. A big
thank you to @ARDiDo, @Consolatis and @jlindgren90 for much of the hard
work.

### Added

- Render overlay layer popups to support sfwbar (issue #239)
- Support HiDPI on-screen-display images for outputs with different scales
- Reload environment variables on SIGHUP (issue #227)
- Add client menu
- Allow applications to start in fullscreen
- Add config option `<core><cycleViewPreview>` to preview the contents
 of each view when cycling through them (for example using alt-tab).
- Allow mouse movements to trigger SnapToEdge. When dragging a view, move
 the cursor outside an output to snap in that direction.
- Unmaximize on Move
- Support wlroots environment variable `WLR_{WL,X11}_OUTPUTS` for running
 in running nested in X11 or a wlroots compositor.
- Support pointer gestures (pinch/swipe)
- Adjust views to account for output layout changes

### Changed

This release contains the following two breaking changes:

- Disabling outputs now causes views to be re-arranged, so in the
 context of idle system power management (for example when using
 swaylock), it is no longer suitable to call wlr-randr {--off,--on}
 to enable/disable outputs.
- The "Drag" mouse-event and the unmaximize-on-move feature require
 slightly different `<mousebind>` settings to feel natural, so suggest
 updating any local `rc.xml` settings in accordance with
 `docs/rc.xml.all`

## [0.4.0] - 2021-12-31

Compile with wlroots 0.15.0

This release contains lots of internal changes, fixes and  new features.
A big thank you goes out to @ARDiDo, @bi4k8, @Joshua-Ashton,
@jlindgren90, @Consolatis, @telent and @apbryan. The most notable
feature-type changes are listed below.

### Added

 `TLCorner`, `Frame`), `buttons` (e.g. `left`, `right`), and
 `mouse actions` (e.g. `Press`, `DoubleClick`). Modifier keys are
 also supported to handle configurations such as `alt` + mouse button
 to move/resize windows. (Written-by: @bi4k8, @apbryan)
 - `<libinput>` configuration. Written-by: @ARDiDo
 - `<resistance><screenEdgeStrength>`
- Support for primary selection. Written-by: @telent

## 1. What is this?

Labwc stands for Lab Wayland Compositor, where lab can mean any of the
following:

- sense of experimentation and treading new ground
- inspired by BunsenLabs and ArchLabs
- your favorite pet

Labwc is a [wlroots]-based window-stacking compositor for [wayland], inspired by
[openbox].

It is light-weight and independent with a focus on simply stacking windows well
and rendering some window decorations. It takes a no-bling/frills approach and
says no to features such as icons (except window buttons), animations,
decorative gradients and any other options not required to reasonably render
common themes. It relies on clients for panels, screenshots, wallpapers and so
on to create a full desktop environment.

Labwc tries to stay in keeping with [wlroots] and [sway] in terms of general
approach and coding style.

Labwc only understands [wayland-protocols] &amp; [wlr-protocols], and it cannot
be controlled with dbus, sway/i3-IPC or other technology. The reason for this is
that we believe that custom IPCs and protocols create a fragmentation that
hinders general Wayland adoption.

In order to avoid reinventing configuration and theme syntax, the [openbox] 3.6
specification is used. This does not mean that labwc is an openbox clone but
rather that configuration files will look and feel familiar.

Labwc supports the following:

- [x] Config files (rc.xml, autostart, environment, menu.xml)
- [x] Theme files and xbm icons
- [x] Basic root-menu and client-menu
- [x] HiDPI
- [x] wlroots protocols such as `output-management`, `layer-shell` and
  `foreign-toplevel`
- [x] Optionally xwayland

See [scope] for full details on implemented features.

## 2. Build and Installation

To build, simply run:

meson build/
    ninja -C build/

Run-time dependencies include:

- wlroots, wayland, libinput, xkbcommon
- libxml2, cairo, pango, glib-2.0
- xwayland, xcb (optional)

Build dependencies include:

- meson, ninja, gcc/clang
- wayland-protocols

Disable xwayland with `meson -Dxwayland=disabled build/`

For OS/distribution specific details see see [wiki].

## 3. Configuration

For a step-by-step initial configuration guide, see [getting-started]

User config files are located at `${XDG_CONFIG_HOME:-$HOME/.config/labwc/}`
with the following four files being used:

| file          | man page
| ------------- | --------
| [rc.xml]      | [labwc-config(5)], [labwc-actions(5)]
| [menu.xml]    | [labwc-menu(5)]
| [autostart]   | [labwc(1)]
| [environment] | [labwc-config(5)]

The example [rc.xml] has been kept simple. For all options and default values,
see [rc.xml.all]

Configuration and theme files are reloaded on receiving SIGHUP
(e.g. `killall -s SIGHUP labwc`)

For keyboard settings, see [environment] and [xkeyboard-config(7)]

## 4. Theming

Themes are located at `~/.local/share/themes/\<theme-name\>/openbox-3/` or
equivalent `XDG_DATA_{DIRS,HOME}` location in accordance with freedesktop XDG
directory specification.

For full theme options, see [labwc-theme(5)] or the [themerc] example file.

For themes, search the internet for "openbox themes" and place them in
`~/.local/share/themes/`. Some good starting points include:

- https://github.com/addy-dclxvi/openbox-theme-collections
- https://github.com/the-zero885/Lubuntu-Arc-Round-Openbox-Theme
- https://bitbucket.org/archlabslinux/themes/
- https://github.com/BunsenLabs/bunsen-themes

## 5. Usage

./build/labwc [-s <command>]

> **_NOTE:_** If you are running on **NVIDIA**, you will need the
> `nvidia-drm.modeset=1` kernel parameter.

If you have not created an rc.xml config file, default bindings will be:

| combination              | action
| ------------------------ | ------
| `alt`-`tab`              | activate next window
| `super`-`return`         | alacritty
| `alt`-`F3`               | bemenu
| `alt`-`F4`               | close window
| `super`-`a`              | toggle maximize
| `alt`-`mouse-left`       | move window
| `alt`-`mouse-right`      | resize window
| `alt`-`arrow`            | move window to edge
| `super`-`arrow`          | resize window to fill half the output
| `XF86_AudioLowerVolume`  | amixer sset Master 5%-
| `XF86_AudioRaiseVolume`  | amixer sset Master 5%+
| `XF86_AudioMute`         | amixer sset Master toggle
| `XF86_MonBrightnessUp`   | brightnessctl set +10%
| `XF86_MonBrightnessDown` | brightnessctl set 10%-

A root-menu can be opened by clicking on the desktop.

## 6. Integration

Suggested apps to use with labwc:

- Screen shooter: [grim]
- Screen recorder: [wf-recorder]
- Background image: [swaybg]
- Panel: [waybar], [yambar], [lavalauncher], [sfwbar]
- Launchers: [bemenu], [fuzzel], [wofi]
- Output managers: [wlopm], [kanshi], [wlr-randr]
- Screen locker: [swaylock]

See [integration] for further details.

## 7. Scope

A lot of emphasis is put on code simplicity when considering features.

The main development effort is focused on producing a solid foundation for a
stacking compositor rather than adding configuration and theming options.

See [scope] for details.

High-level summary of items which are not intended to be implemented:

- Icons (except window buttons)
- Animations
- Gradients for decoration and menus
- Any theme option not required to reasonably render common themes (it is
  amazing how few options are actually required).

# NAME

labwc - configuration files

# CONFIGURATION

Labwc uses openbox-3.6 specification for configuration and theming, but does not
support all options. The following files form the basis of the labwc
configuration: rc.xml, menu.xml, autostart and environment.

No configuration files are needed to start and run labwc.

In accordance with XDG Base Directory Specification, configuration files are
searched for in the following order:

- ${XDG_CONFIG_HOME:-$HOME/.config}/labwc
- ${XDG_CONFIG_DIRS:-/etc/xdg}/labwc

All configuration and theme files except autostart are re-loaded on receiving
signal SIGHUP.

The *autostart* file is executed as a shell script. This is the place for
executing clients for handling background images, panels and similar.

The *environment* file is parsed as *variable=value* and sets environment
variables accordingly. It is recommended to specify keyboard layout settings and
cursor size/theme here; see environment variable section below for details. Note
that the environment file is treated differently by openbox where it is simply
sourced prior to running openbox.

The *menu.xml* file defines the context/root-menus and is described in
labwc-menu(5)

There is a small <theme> section in rc.xml, for example to set rouned corners,
but the remainder of the theme specification and associated files are described
in labwc-theme(5).

*rc.xml* is the main configuration file and all its options are described in
detail below. Configuration must be wrapped in a <labwc_config> root-element,
like this:

```
<?xml version="1.0"?>
<labwc_config>

</labwc_config>
```

The rest of this man page describes configuration options.

## CORE

*<core><decoration>* [server|client]
	Specify server or client side decorations for xdg-shell views. Note
	that it is not always possible to turn off client side decorations.
	Default is server.

*<core><gap>*
	The distance in pixels between views and output edges when using
	movement actions, for example MoveToEdge. Default is 0.

*<core><adaptiveSync>* [yes|no]
	Enable adaptive sync. Default is no.

*<core><cycleViewPreview>* [yes|no]
	Preview the contents of the selected window when cycling between windows.
	Default is no.

*<core><cycleViewOutlines>* [yes|no]
	Draw an outline around the selected window when cycling between windows.
	Default is yes.

## RESISTANCE

*<resistance><screenEdgeStrength>*
	Screen Edge Strength is how far past the screen's edge your cursor must
	move before the window will move with it. Resistance is counted in
	pixels. Default is 20 pixels.

## FOCUS

*<focus><followMouse>* [yes|no]
	Make focus follow mouse, i.e. focus is given to window under mouse
	cursor. Default is no.

*<focus><raiseOnFocus>* [yes|no]
	Raise window to top when focused. Default is no.

## WINDOW SNAPPING

*<snapping><range>*
	The distance in pixels from the edge of an ouput for window Move
	operations to trigger SnapToEdge. A range of 0 disables window snapping.
	Default is 1.

*<snapping><topMaximize>* [yes|no]
	Maximize window if Move operation ends on the top edge. Default is yes.

## WORKSPACES

*<desktops><names><name>*
	Define workspaces. A workspace covers all outputs. The OSD only shows
	windows on the current workspace. Workspaces can be switched to with
	GoToDesktop and windows can be moved with SendToDesktop. See
	labwc-actions(5) for more information about their arguments.

*<desktops><popupTime>*
	Define the timeout after which to hide the workspace OSD.
	A setting of 0 disables the OSD. Default is 1000 ms.

## THEME

*<theme><cornerRadius>*
	The radius of server side decoration top corners. Default is 8.

*<theme>*
	The font to use for a specific element of a window, menu or OSD.
	Places can be any of:
	- ActiveWindow - titlebar of active window
	- MenuItem - menu item (currently only root menu)
	- OnScreenDisplay - items in the on screen display
	If no place attribute is provided, the setting will be applied to all
	places.

*<theme><name>*
	Describes font name. Default is sans.

*<theme><size>*
	Font size in pixels. Default is 10.

*<theme><slant>*
	Font slant (normal or italic). Default is normal.

*<theme><weight>*
	Font weight (normal or bold). Default is normal.

## KEYBOARD

*<keyboard><keybind key="">*
	Define a key binding in the format *modifier-key*, where supported
	modifiers include S (shift); C (control); A (alt); W (super). Unlike
	Openbox, multiple space-separated key combinations and key-chains are
	not supported.

*<keyboard><keybind key=""><action name="">*
	Keybind action. See labwc-action(5)

*<keyboard><default />*
	Load the default keybinds listed below. This is an addition to the
	openbox specification and provides a way to keep config files simpler
	whilst allowing your specific keybinds.
	Note that if no rc.xml is found, or if no <keyboard><keybind> entries
	exist, the same default keybinds will be loaded even if the <default />
	element is not provided.

```
 A-Tab - next window
 W-Return - alacritty
 A-F3 - run bemenu
 A-F4 - close window
 W-a - toggle maximize
 A-<arrow> - move window to edge
 W-<arrow> - resize window to fill half the output
```

Audio and MonBrightness keys are also bound to amixer and
	brightnessctl respectively

*<keyboard><repeatRate>*
	Set the rate at which keypresses are repeated per second.
	Default is 25.

	Default is 600.

## MOUSE

*<mouse><doubleClickTime>*
	Set double click time in milliseconds. Default is 500.

*<mouse><context name=""><mousebind button="" direction=""><action>*
	Multiple *<mousebind>* can exist within one *<context>*; and multiple
	*<action>* can exist within one *<mousebind>*

Define a mouse binding. Supported context-names include:
	- TitleBar: The decoration on top of the window, where the window
	  buttons and the window title are shown.
	- Title: The area of the titlebar (including blank space) between
	  the window buttons, where the window title is displayed.
	- WindowMenu: The button on the left.
	- Iconify: The button that looks like an underline.
	- Maximize: The button that looks like a box.
	- Close: The button that looks like an X.
	- Top: The top edge of the window's border.
	- Bottom: The bottom edge of the window's border.
	- Left: The left edge of the window's border.
	- Right: The right edge of the window's border.
	- TRCorner: The top-right corner of the window's border.
	- TLCorner: The top-left corner of the window's border.
	- BLCorner: The bottom-left corner of the window's border.
	- BRCorner: The bottom-right edge of the window's border.
	- Client: The client area of a window, inside its decorations.
	  Events bound to Client are also passed to applications.
	- Frame: Any part of a window, but events bound to Frame are not passed
	  through to the application.
	- Desktop: The desktop background, where no windows are present.
	- Root: A synonym for Desktop (for compatibility).

Supported mouse *buttons* are:
	- Left
	- Middle
	- Right

Supported scroll *directions* are:

	- Release: Releasing the specified button in the context.
	- Click: Pressing and then releasing inside of the the context.
	- DoubleClick: Two presses within the doubleClickTime.
	- Drag: Pressing the button within the context, then moving the cursor.
	- Scroll: Scrolling in specified *direction* in the context.

*<mouse><default />*
	Load default mousebinds. This is an addition to the openbox
	specification and provides a way to keep config files simpler whilst
	allowing user specific binds. Note that if no rc.xml is found, or if no
	<mouse><mousebind> entries exist, the same default mousebinds will be
	loaded even if the <default /> element is not provided.

## LIBINPUT

*<libinput><device category="">*
	Define a category of devices to use the configuration values that
	follow. The category can be set to touch (devices that define a width
	and height), non-touch, default, or the name of a device. You can obtain
	your devices name by running *libinput list-devices* (you may need to
	be root or a part of the input group to perform this.) Any members of
	this category that are not set use the default for the device. With the
	exception of tap-to-click, which is enabled by default.

*<libinput><device category=""><naturalScroll>* [yes|no]
	Use natural scrolling for this category if available.

*<libinput><device category=""><leftHanded>* [yes|no]
	Use your devices left-handed mode if available.

*<libinput><device category=""><pointerSpeed>* [\-1.0 to 1.0]
	Set the pointer speed for this category. The speed is a number between
	\-1.0 and 1.0, with 0.0 being the default in most cases, and 1.0 being
	the fastest.

*<libinput><device category=""><accelProfile>* [flat|adaptive]
	Set the pointer's acceleration profile for this category. Flat applies
	no acceleration (the pointers velocity is constant), while adaptive
	changes the pointers speed based the actual speed of your mouse or
	finger on your touchpad.

*<libinput><device category=""><tap>* [yes|no]
	Enable or disable tap-to-click for this category. This is enabled by
	default for all categories.

*<libinput><device category=""><tapButtonMap>* [lrm|lmr]
	Set the buttons mapped to one-, two-, and three-finger taps to the
	left button, right button, and middle button, respectively (lrm) (the
	default), or to left button, middle button, and right button (lmr).

*<libinput><device category=""><middleEmulation>* [yes|no]
	Enable or disable middle button emulation for this category. Middle
	emulation processes a simultaneous left and right click as a press of
	the middle mouse button (scroll wheel).

*<libinput>device category=""><disableWhileTyping>* [yes|no]
	Enable or disable disable while typing for this category. DWT ignores
	any motion events while a keyboard is typing, and for a short while
	after as well.

## ENVIRONMENT VARIABLES

*XCURSOR_THEME* and *XCURSOR_SIZE* are supported to set cursor theme
and size respectively. The default size is 24. System cursor themes can
typically be found with a command such as:

```
find /usr/share/icons/ -type d -name "cursors"
```

The following keyboard-configuration variables are supported:
*XKB_DEFAULT_RULES*, *XKB_DEFAULT_MODEL*, *XKB_DEFAULT_LAYOUT*,
*XKB_DEFAULT_VARIANT* and *XKB_DEFAULT_OPTIONS*.

See xkeyboard-config(7) for details.

# NAME

labwc - menu files

# DESCRIPTION

Static menus are built based on content of XML files located at
"~/.config/labwc" and equivalent XDG Base Directories.

# SYNTAX

A menu file must be entirely enclosed within <openbox_menu> and
</openbox_menu> tags. Inside these tags, menus are specified as follows:

```
<menu id="">

<item label="">
 <action></action>
 </item>

<menu id="" />

<menu id="" label="">
 ...some content...
 </menu>

</menu>
```

*menu.id*
	Each menu must be given an id, which is a unique identifier of the menu.
	This id is used to refer to the menu in a ShowMenu action.

*menu.label*
	The title of the menu, shown in its parent. A label must be given when
	defining a menu.

*menu.item.label*
	The visible name of the menu item.

*menu.item.action*
	See labwc-action(5)

# NAME

labwc - theme files

# THEME

The theme engine aims to be compatible with openbox and themes will be
searched for in the following order:

- ${XDG_DATA_HOME:-$HOME/.local/share}/themes/<theme-name>/openbox-3/
- $HOME/.themes/<theme-name>/openbox-3/
- /usr/share/themes/<theme-name>/openbox-3/
- /usr/local/share/themes/<theme-name>/openbox-3/
- /opt/share/themes/<theme-name>/openbox-3/

Choosing a theme is done by editing the <name> key in the <theme> section of
the rc.xml configuration file (labwc-config(5)).

A theme consists of a themerc file and optionally some xbm icons.

# DATA TYPES

*color RGB values*
	Colors can be specified by hexadecimal RGB values in the format #rrggbb.
	Other formats will be supported later for better openbox theme
	compatibility.

*justification*
	Justification determines the horizontal alignment of text. Valid options
	are Left, Center and Right.

# THEME ELEMENTS

*border.width*
	Line width (integer) of border border drawn around window frames.
	Default is 1.

*padding.height*
	Vertical padding size, used for spacing out elements in the window decorations.
	Default is 3.

*menu.overlap.x*
	Horizontal overlap in pixels between submenus and their parents. A
	positive value move submenus over the top of their parents, whereas a
	negative value creates a gap between submenus and their parents.
	Default is 0.

*menu.overlap.y*
	Vertical offset in pixels between submenus and their parents. Positive
	values for downwards and negative for upwards. Default is 0.

*window.active.border.color*
	Border color of active window

*window.inactive.border.color*
	Border color of inactive window

*window.active.title.bg.color*
	Background color for the focussed window's titlebar

*window.inactive.title.bg.color*
	Background color for non-focussed windows' titlebars

*window.active.label.text.color*
	Text color for the focussed window's titlebar

*window.inactive.label.text.color*
	Text color non-focussed windows' titlebars

*window.label.text.justify*
	Specifies how window titles are aligned in the titlebar for both
	focused and unfocused windows. Type justification. Default Left.

*window.active.button.unpressed.image.color*
	Color of the images in titlebar buttons in their default, unpressed,
	state. This element is for the focused window.

*window.inactive.button.unpressed.image.color*
	Color of the images in titlebar buttons in their default, unpressed,
	state. This element is for non-focused windows.

Note: The button elements (i.e. window.[in]active.button.\*) support defining
different types of buttons individually by inserting the type ("iconify", "max"
and "close") after the button node. For example:
window.active.button.iconify.unpressed.image.color
This syntax is not not documented on the openbox.org wiki, but is supported by
openbox and is used by many popular themes. For the sake of brevity, these
elements are not listed here, but are supported.

*menu.items.bg.color*
	Background color of inactive menu items

*menu.items.text.color*
	Text color of inactive menu item

*menu.items.active.bg.color*
	Background color of active menu items

	Text color of active menu item

*menu.separator.width*
	Line thickness of menu separators. Default 1.

*menu.separator.padding.width*
	Space on the left and right side of each separator line. Default 6.

*menu.separator.padding.height*
	Space above and below each separator line. Default 3.

*menu.separator.color*
	Menu separator color. Default #888888.

*osd.bg.color*
	Background color of on-screen-display

*osd.border.color*
	Border color of on-screen-display

*osd.border.width*
	Border width of on-screen-display

*osd.label.text.color*
	Text color of on-screen-display

*border.color*
	Set all border colors. This is obsolete, but supported for backward
	compatibility as some themes still contain it.

# BUTTONS

The images used for the titlebar buttons are 1-bit xbm (X Bitmaps). These are
masks where 0=clear and 1=colored. The xbm image files are placed in the same
directory within your theme as the themerc file. Here are all the possible xbm
files looked for:

- max.xbm
- iconify.xbm
- close.xbm
- menu.xbm

More will be supported later.

Note: menu.xbm is not part of openbox-3.6 spec

# DEFINITIONS

The handle is the window edge decoration at the bottom of the window.

# DERIVED DIMENSIONS

The window title bar height is equal to the vertical font extents of the title.
Padding will be added to this later.

# NAME

labwc - a wayland stacking compositor

# SYNOPSIS

*labwc*  [options...]

# DESCRIPTION

Labwc is a wlroots-based stacking compositor for wayland.

It is light-weight and independent with a focus on simply stacking windows
well and rendering some window decorations. Where practicable it uses clients
for wall-paper, panels, screenshots and so on.

The compositor will exit or reload its configuration upon receiving SIGTERM
and SIGHUP respectively.  For example:

```
kill -s <signal> $LABWC_PID
killall -s <signal> labwc
```

Each running instance of labwc sets the environment variable `LABWC_PID` to
its PID. This is useful for sending signals to a specific instance and is what
the `--exit` and `--reconfigure` options use.

# OPTIONS

*-c, --config* <config-file>
	Specify a config file with path

*-C, --config-dir* <config-directory>
	Specify a config directory

*-d, --debug*
	Enable full logging, including debug information

*-e, --exit*
	Exit the compositor

*-h, --help*
	Show help message and quit

*-r, --reconfigure*
	Reload the compositor configuration

*-s, --startup* <command>
	Run command on startup

*-v, --version*
	Show the version number and quit

*-V, --verbose*
	Enable more verbose logging

 S - shift

Use <keyboard><default /> to load all the default keybinds (those listed
 below). If the default keybinds are largely what you want, a sensible
 approach could be to start the <keyboard> section with a <default />
 element, and then (re-)define any special binds you need such as launching
 your favourite terminal or application launcher.

 <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.

<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.

<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.

<request name="set_anchor">
 <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.
 </description>
 <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.

<enum name="keyboard_interactivity">
 <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.

<request name="set_keyboard_interactivity">

 Set how keyboard events are delivered to this surface. By default,
 layer shell surfaces do not receive keyboard events; this request can

This setting is inherited by child surfaces set by the get_popup

Layer surfaces receive pointer, touch, and tablet events normally. If

        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.

<description summary="protocol to configure output devices">
 This protocol exposes interfaces to obtain and modify output device
 configuration.

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.
 </description>

<interface name="zwlr_output_manager_v1" version="2">
 <description summary="output device configuration manager">
 This interface is a manager that allows reading and writing the current
 output device configuration.

Output devices that display pixels (e.g. a physical monitor or a virtual
      output in a window) are represented as heads. Heads cannot be created nor
      destroyed by the client, but they can be enabled or disabled and their
      properties can be changed. Each head may have one or more available modes.

Whenever a head appears (e.g. a monitor is plugged in), it will be
      advertised via the head event. Immediately after the output manager is
      bound, all current heads are advertised.

Whenever a head's properties change, the relevant wlr_output_head events
      will be sent. Not all head properties will be sent: only properties that
      have changed need to.

Whenever a head disappears (e.g. a monitor is unplugged), a
      wlr_output_head.finished event will be sent.

After one or more heads appear, change or disappear, the done event will
      be sent. It carries a serial which can be used in a create_configuration
      request to update heads properties.

The information obtained from this protocol should only be used for output
 configuration purposes. This protocol is not designed to be a generic
 output property advertisement protocol for regular clients. Instead,
 protocols such as xdg-output should be used.

 sent whenever a head or mode is created or destroyed and whenever one of
 their properties has been changed. Not all state is re-sent each time
 the current configuration changes: only the actual changes are sent.

<interface name="zwlr_output_head_v1" version="2">
 <description summary="output device">
 A head is an output device. The difference between a wl_output object and
 a head is that heads are advertised even if they are turned off. A head
 object only advertises properties and cannot be used directly to change
 them.

A head has some read-only properties: modes, name, description and
      physical_size. These cannot be changed by clients.

Other properties can be updated via a wlr_output_configuration object.

Properties sent via this interface are applied atomically via the
 wlr_output_manager.done event. No guarantees are made regarding the order
 in which properties are sent.

<event name="name">
 <description summary="head name">
 This event describes the head name.

The naming convention is compositor defined, but limited to alphanumeric
        characters and dashes (-). Each name is unique among all wlr_output_head
        objects, but if a wlr_output_head object is destroyed the same name may
        be reused later. The names will also remain consistent across sessions
        with the same hardware and software configuration.

Examples of names include 'HDMI-A-1', 'WL-1', 'X11-1', etc. However, do
        not assume that the name is a reflection of an underlying DRM
        connector, X11 connection, etc.

If the compositor implements the xdg-output protocol and this head is
        enabled, the xdg_output.name event must report the same name.

The name event is sent after a wlr_output_head object is created. This
 event is only sent once per object, and the name does not change over
 the lifetime of the wlr_output_head object.

Usage: $P [OPTION]... [FILE]...
Version: $V

Options:
 -q, --quiet quiet
 -v, --verbose verbose mode
 --no-tree run without a kernel tree
 --no-signoff do not check for 'Signed-off-by' line
 --patch treat FILE as patchfile (default)
 --emacs emacs compile window format
 --terse one line per report
 --showfile emit diffed file position, not input file position
 -g, --git treat FILE as a single commit or git revision range
 single git commit with:
 <rev>
 <rev>^
 <rev>~n
 multiple git commits with:
 <rev1>..<rev2>
 <rev1>...<rev2>
 <rev>-<count>
 git merges are ignored
 -f, --file treat FILE as regular source file
 --subjective, --strict enable more subjective tests
 --list-types list the possible message types
 --types TYPE(,TYPE2...) show only these comma separated message types
 --ignore TYPE(,TYPE2...) ignore various comma separated message types
 --show-types show the specific message type in the output
 --max-line-length=n set the maximum line length, (default $max_line_length)
 if exceeded, warn on patches
 requires --strict for use with --file
 --min-conf-desc-length=n set the min description length, if shorter, warn
 --tab-size=n set the number of spaces for tab (default $tabsize)
 --root=PATH PATH to the kernel tree root
 --no-summary suppress the per-file summary
 --mailback only produce a report in case of warnings/errors
 --summary-file include the filename in summary
 --debug KEY=[0|1] turn on/off debugging of KEY, where KEY is one of
 'values', 'possible', 'type', and 'attr' (default
 is all off)
 --test-only=WORD report only warnings/errors containing WORD
 literally
 --fix EXPERIMENTAL - may create horrible results
 If correctable single-line errors exist, create
 "<inputfile>.EXPERIMENTAL-checkpatch-fixes"
 with potential errors corrected to the preferred
 checkpatch style
 --fix-inplace EXPERIMENTAL - may create horrible results
 Is the same as --fix, but overwrites the input
 file. It's your fault if there's no backup or git
 --ignore-perl-version override checking of perl version. expect
 runtime errors.
 --codespell Use the codespell dictionary for spelling/typos
 (default:/usr/share/codespell/dictionary.txt)
 --codespellfile Use this codespell dictionary
 --typedefsfile Read additional types from this file
 --color[=WHEN] Use colors 'always', 'never', or only when output
 is a terminal ('auto'). Default is 'auto'.
 --kconfig-prefix=WORD use WORD as a prefix for Kconfig symbols (default
 ${CONFIG_})
 -h, --help, --version display this help and exit

When FILE is - read standard input.

/**
 * TODO
 *
 * This implementation does not react to output scale changes itself but only
 * to movement of scene nodes to different outputs. To also handle output scale
 * changes we'd need to keep a list of struct wlr_outputs * in sync and listen
 * to their commit signals.
 *
 * The detection of the max output scale is also not 100% robust for all use
 * cases as on output_enter we only compare the new output scale with the
 * primary_output scale. In specific conditions the primary output may be the
 * same as the new output even though a smaller part of the buffer node is
 * still visible on an output with a bigger scale. This could be solved the
 * same way as the previous point in keeping a list of outputs in sync.
 *
 * Most of this would be easier when wlroots would instead provide a
 * max_scale_changed event because it already touches all the relevant parts
 * when calculating the primary_output and inform wlr_scene_buffers about
 * output changes.
 *
 * See wlroots/types/scene/wlr_scene.c scene_buffer_update_outputs()
