@ -14,6 +14,9 @@ Note that bug reports and feature requests for related projects should be filed
having access to the source code is too time-consuming. Additionally,
experience has shown that often, the software in question is responsible for
the issue. Please raise an issue with the software in question, not i3.
5. Please note that i3 does not support compositors (e.g. compton). If you
encountered the issue you are about to report while using a compositor,
please try reproducing it without a compositor.

# i3 project governance
## Overview
The i3 project uses a governance model commonly described as Benevolent
Dictator For Life (BDFL). This document outlines our understanding of what this
means.
## Roles
* user: anyone who interacts with the i3 project
* core contributor: a handful of people who have contributed significantly to
the project by any means (issue triage, support, documentation, code, etc.).
Core contributors are recognizable via GitHub’s “Member” badge.
* BDFL: a single individual who makes decisions when consensus cannot be
reached. i3’s current BDFL is [@stapelberg](https://github.com/stapelberg).
## Decision making process
In general, we try to reach consensus in discussions. In case consensus cannot
be reached, the BDFL makes a decision.
For feature requests and code contributions specifically, the values with which
we consider them can be found on the bottom of https://i3wm.org/. These values
are not set in stone and are to be treated as guiding principles, not absolute
rules that must be followed in every case.
## Contribution process
Please see [CONTRIBUTING](CONTRIBUTING.md).

Version 0.18
=head1 SYNOPSIS
This module connects to the i3 window manager using the UNIX socket based
IPC interface it provides (if enabled in the configuration file). You can
then subscribe to events or send messages and receive their replies.
use AnyEvent::I3 qw(:all);
my $i3 = i3();
$i3->connect->recv or die "Error connecting";
say "Connected to i3";
my $workspaces = $i3->message(TYPE_GET_WORKSPACES)->recv;
say "Currently, you use " . @{$workspaces} . " workspaces";
...or, using the sugar methods:
use AnyEvent::I3;
my $workspaces = i3->get_workspaces->recv;
say "Currently, you use " . @{$workspaces} . " workspaces";
A somewhat more involved example which dumps the i3 layout tree whenever there
is a workspace event:
use Data::Dumper;
use AnyEvent;
use AnyEvent::I3;
my $i3 = i3();
$i3->connect->recv or die "Error connecting to i3";
$i3->subscribe({
workspace => sub {
$i3->get_tree->cb(sub {
my ($tree) = @_;
say "tree: " . Dumper($tree);
});
}
})->recv->{success} or die "Error subscribing to events";
AE::cv->recv
=head1 EXPORT
=head2 $i3 = i3([ $path ]);
Creates a new C<AnyEvent::I3> object and returns it.
C<path> is an optional path of the UNIX socket to connect to. It is strongly
advised to NOT specify this unless you're absolutely sure you need it.
C<AnyEvent::I3> will automatically figure it out by querying the running i3
instance on the current DISPLAY which is almost always what you want.

use it to print an appropriate message and exit cleanly or to try to reconnect.

┌────────────────────────────┐
│ Release notes for i3 v4.13 │
└────────────────────────────┘
This is i3 v4.13. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.
For users, there are two changes to be aware of:
1. The X server DPI is read from the Xft.dpi X resource (if available).
Previously, i3 used to directly look at the X server’s DPI (based on screen
resolution and physical size). Looking at Xft.dpi is more consistent with
other software, more likely to be correct (because it’s user-specified and
not read from possibly broken hardware information) and allows users to
override the value.
2. It is now possible to set config file variables from X resources using the
“set_from_resource” directive. This allows users to have a single source of
truth for e.g. theming X11 applications (specify “*color0: #121212” and have
it apply to URxvt and your i3 config).
For packagers, there are three changes that likely require action:
1. cairo/pango are now required dependencies, as announced in the i3 v4.12
release notes.
2. The aforementioned “set_from_resource” feature requires the new dependency
libxcb-util-xrm.
3. i3 now uses the GNU build system (autotools). Please see
https://github.com/i3/i3/commit/4a52a7e9fb6fb2e1f0256b2e086cfa313f411cd8 for
a lot more details about the rationale and what this means for your package.
Bottomline, things should get simpler for you, though :).
┌────────────────────────────┐
│ Changes in i3 v4.13 │
└────────────────────────────┘
• build: wire up version handling for non-release tarballs (as opposed to git
checkouts)
• build: switch to the GNU build system
• i3bar: disable pango markup for plain-text input
• man/i3-msg: point out default ipc message type
• config: introduce support for specifying variables from X resources
• config: ensure variables match on longest-length, eliminating problems
where one variable was a prefix of another
• config: do not count '\' in comment lines as line continuation
• ipc: introduce a new GET_BINDING_MODES command
• ipc: implement new window::mark event
• ipc: add “output” to IPC events referencing a container
• make fullscreen windows open on the output which is indicated by their
geometry (fixes LibreOffice Impress multi-monitor presentations)
• focus newly managed windows only if they don’t use the globally active
input mode (fixes issues with RubyMine)
• remove title indentation in nested containers (rationale was unclear,
nobody spoke up when we asked about the feature on i3-discuss)
• use the last known timestamp when calling xcb_set_input_focus (might fix
rare race conditions in focus handling)
• introduce the “smart” option for hide_edge_borders, which will hide borders
when there is precisely one window on the workspace
• handle _MOTIF_WM_HINTS changes (_MOTIF_WM_HINTS were previously only
considered when managing a new window)
• don’t change border style if BS_NORMAL is requested in _MOTIF_WM_HINTS
• only add numlock fallback for keybindings where necessary (allows users to
correctly bind keys on the numpad)
• do not match docks in config and command criteria
• get DPI from the Xft.dpi resource instead of directly looking at the screen
resolution/size
• handle _NET_ACTIVE_WINDOW for scratchpad windows (for pagers)
• set _NET_WM_DESKTOP to sticky for scratchpad windows
• add new criteria “tiling” and “floating”
• implement special output name “current” for commands
• handle ResizeRequests for tray clients (fixes VLC tray icon)
┌────────────────────────────┐
│ Bugfixes │
└────────────────────────────┘
• i3bar: fix crash when the I3SOCK environment variable is present
• i3-dmenu-desktop: do not die on failed open
• i3-input: properly position in non-standard cases (fixes an issue where
i3-input would launch off-screen)
• i3-save-tree: rename “mark” to “marks” to reflect our recent change to
allow multiple marks
• mouse bindings: only grab the mouse buttons that need to be grabbed
• no_focus: correctly count the number of windows (makes no_focus work with
tabbed/stacked workspace layouts).
• properly close disabled outputs restored during a restart (this fixes state
handling when RandR changes happen during i3 restarts)
• don’t trigger bindings on window border clicks unless --border was
specified for the binding
• traverse numbered workspaces in correct order
• fix transition from named to numbered workspaces in “workspace next|prev”
• avoid setting urgency hint on content containers and above (fixes crashes)
• don’t trigger unrelated key bindings for --release bindings
• fix colormap handling for containers (fixes taking screenshots using xwd)
• check output crossing on ENTER_NOTIFY to dockarea (fixes pointer jumping)
• fix a use-after-free bug (fixes “floating enable” on single split windows)

┌────────────────────────────┐
│ Release notes for i3 v4.14 │
└────────────────────────────┘
This is i3 v4.14. This version is considered stable. All users of i3 are
strongly encouraged to upgrade.
Aside from many bug and documentation fixes, the “swap” command is a notable
addition of this release. As is almost tradition at this point, keybinding
handling has seen some fixes as well. A noticeable change for users with such
monitors is i3’s support for RandR 1.5, which transparently supports the TILE
property of first-gen 4K monitors and current 5K or 8K monitors.
┌────────────────────────────┐
│ Changes in i3 v4.14 │
└────────────────────────────┘
• build: link libiconv explicitly for systems which need it
• build: move AnyEvent-I3 into the i3 repository
• docs/hacking-howto: add compilation instructions
• docs/ipc: add missing cases to the workspace event
• docs/ipc: document the “primary” field of the OUTPUTS reply
• docs/ipc: replace Go IPC library with a maintained one
• docs/ipc: add link to the ocaml-i3ipc library
• docs/ipc: fix invalid trailing commas in JSON examples
• docs/layout-saving: add section about troubleshooting window titles
• docs/testsuite: update for the move to autotools
• docs/userguide: clarify the move command syntax
• docs/userguide: correct “Esc” to “Escape”
• docs/userguide: clarify focus_follows_mouse behavior

• i3bar: restart bar status command on reload if it changed
• i3bar: treat left/right scrolling like up/down scrolling
• i3bar: accept “primary” in the “output” configuration directive
• i3-input: do not set input focus, grabbing the keyboard suffices
• i3-msg: return an exit code when missing the -t argument
• i3-sensible-editor: correct “mc-edit” to “mcedit”
• i3-sensible-terminal: add lilyterm, tilix, terminix, konsole
• respect SYSCONFDIR when looking for the default xdg directory
• use RandR 1.5 to query screens, supporting the TILE property commonly used
by multi-stream transport (MST) monitors, such as first-gen 4K monitors, or
current 5K and 8K monitors
• respect minimum size hints for floating windows
• support the _NET_MOVERESIZE_WINDOW client message (for e.g. wmctrl)

=== How to build?
You can build i3 like you build any other software package which uses autotools.
Here’s a memory refresher:
$ autoreconf -fi
$ mkdir -p build && cd build
$ ../configure
$ make -j8
(The autoreconf -fi step is unnecessary if you are building from a release tarball,
but shouldn’t hurt either.)
==== Build system features
* We use the AX_ENABLE_BUILDDIR macro to enforce builds happening in a separate
directory. This is a prerequisite for the AX_EXTEND_SRCDIR macro and building
in a separate directory is common practice anyway. In case this causes any
trouble when packaging i3 for your distribution, please open an issue.
* “make check” runs the i3 testsuite. See docs/testsuite for details.
* “make distcheck” (runs testsuite on “make dist” result, tiny bit quicker
feedback cycle than waiting for the travis build to catch the issue).
* “make uninstall” (occasionally requested by users who compile from source)
* “make” will build manpages/docs by default if the tools are installed.
Conversely, manpages/docs are not tried to be built for users who don’t want
to install all these dependencies to get started hacking on i3.
* non-release builds will enable address sanitizer by default. Use the
--disable-sanitizers configure option to turn off all sanitizers, and see
--help for available sanitizers.
* Support for pre-compiled headers (PCH) has been dropped for now in the
interest of simplicity. If you need support for PCH, please open an issue.
* Coverage reports are now generated using “make check-code-coverage”, which
requires specifying --enable-code-coverage when calling configure.

=== Placeholders using window title matches don't swallow the window
If you use the +title+ attribute to match a window and find that it doesn't
work or only works sometimes, the reason might be that the application sets the
title only after making the window visible. This will be especially true for
programs running inside terminal emulators, e.g., +urxvt -e irssi+ when
matching on +title: "irssi"+.
One way to deal with this is to not rely on the title, but instead use, e.g.,
the +instance+ attribute and running the program to set this window instance to
that value:

=== Focus follows mouse
By default, window focus follows your mouse movements. However, if you have a
setup where your mouse usually is in your way (like a touchpad on your laptop
which you do not want to disable completely), you might want to disable 'focus
follows mouse' and control focus only by using your keyboard. The mouse will
still be useful inside the currently active window (for example to click on
links in your browser window).

=== Swapping containers
Two containers can be swapped (i.e., move to each other's position) by using
the +swap+ command. They will assume the position and geometry of the container
they are swapped with.
The first container to participate in the swapping can be selected through the
normal command criteria process with the focused window being the usual
fallback if no criteria are specified. The second container can be selected
using one of the following methods:
+id+:: The X11 window ID of a client window.
+con_id+:: The i3 container ID of a container.
+mark+:: A container with the specified mark, see <<vim_like_marks>>.
Note that swapping does not work with all containers. Most notably, swapping
floating containers or containers that have a parent-child relationship to one
another does not work.
*Syntax*:
----------------------------------------
swap container with id|con_id|mark <arg>
----------------------------------------
*Examples*:

workspace and ignore the text part. So even when the workspace has been renamed
