i3-msg, i3-input, i3-nagbar and i3-config-wizard do not introduce any new
dependencies.
i3-wsbar is implemented in Perl and has the following dependencies:
• IPC::Run
• Try::Tiny
• AnyEvent
• AnyEvent::I3
All of them are available at CPAN, see http://search.cpan.org/
Use your distribution’s packages or cpan(1) to install them.
i3-migrate-config-to-v4.pl is implemented in Perl, but it has no dependencies
besides Perl 5.10.

Release notes for i3 v3.δ-bf1
-----------------------------
This is the first bugfix release (bf1) for version 3.δ (transcribed 3.d) of
i3. Because many bugs were fixed after the release of version 3.δ, we thought
users of the stable releases might profit from this additional bugfix release.
Thanks for this release go out to msi, merovius, Grauwolf, jace, Syntropy,
Mirko, helgiks and Moredread.
A list of changes follows:
* Bugfix: Don’t draw window title when titlebar is disabled
* Bugfix: Correctly switch border types for floating windows
* Bugfix: Correctly replay pointer if the click handler does not trigger
* Bugfix: Also allow WORDs as workspace names
* Bugfix: Correctly clear the urgency hint if a window gets unmapped without
clearing it
* Bugfix: Fix resizing of floating windows in borderless/1-px-border mode
* Bugfix: Accept underscores in bindsym
* Bugfix: Don’t set the urgency flag if the window is focused
* Bugfix: Handle stack-limit cols on tabbed containers
* Bugfix: Resize client after updating base_width/base_height
* Bugfix: Force render containers after setting the client active
* Bugfix: Fix two problems in resizing floating windows with right mouse
* Bugfix: Use more precise floating point arithmetics
* Bugfix: Correctly place new windows below fullscreen windows

Release notes for i3 v3.ε
-----------------------------
This is the fifth version (3.ε, transcribed 3.e) of i3. It is considered
stable.
A really big change in this release is the support of RandR instead of
Xinerama. The Xinerama API is a subset of RandR and its limitations clearly
showed when you reconfigured outputs using xrandr(1) during runtime (it was
not designed to handle such changes). The implementation of RandR fixes some
long-standing bugs (workspaces were messed up when reconfiguring outputs)
and cleans up some code. Furthermore, you are now able to assign workspaces
to outputs (like LVDS1, VGA1, …) instead of the formerly used heuristics
like "the screen at position (x, y)" or "the second screen in the list".
Furthermore, another big change is the separation of debug output (the
so-called logfile): you now need to enable verbose output (parameter -V)
and you need to specify which (if any) debug output you want to see (parameter
-d <loglevels>). When starting without -V, i3 will only log errors. This is
what you usually want for a production system. When enabling verbose output,
you will see the names and window classes of new windows (useful for creating
assignments in your configuration file) and other useful messages. For an
explanation of the debuglevels, please see the "How to debug" document (for
the impatient: "-d all" gives you full output).
In 3.δ, a new parser/lexer was introduced and available using the -l option.
The old parser/lexer has been removed in the meantime, so in 3.ε, the "new"
parser/lexer is always used and you do not need the -l option anymore. To
make debugging errors in your configuration easier, the error messages have
been very much improved. Also, the parser tries to skip invalid lines (though
it may not always succeed, it usually works and does not crash i3).
Starting from version 3.ε, i3 obeys the XDG base directory specification,
meaning that you can now put your configuration file into ~/.config/i3/config,
which might be useful if you manage your ~/.config directory in some way (git,
…). The old configuration file path is still supported (there are no plans
to change this), but using ~/.config seems reasonable for clean setups.
You can disable the internal workspace bar in this release. Instead of the
internal bar, you can use dzen2 (or similar) in dock mode (-dock for dzen2,
but you need an svn revision). The sample implementation i3-wsbar takes
stdin, generates a combined bar (workspaces + stdin) and starts dzen2 on
your outputs as needed (does the right thing when you reconfigure your
monitors dynamically).
To accomplish the external workspace bar feature, the IPC interface has
seen much love: requests and replies now use JSON for serialization of
data structures and provide a nice and simple way to get information (like
the current workspaces or outputs) from i3 or send commands to it. You can
also subscribe to certain types of events (workspace or output changes).
See the AnyEvent::I3 module for a sample implementation of a library.
Thanks for this release go out to Merovius, badboy, xeen, Atsutane, Ciprian,
dirkson, Mirko, sur5r, artoj, Scytale, fallen, Thomas, Sasha, dothebart, msi
and all other people who reported bugs/made suggestions.
A complete list of changes follows:
* Implement RandR instead of Xinerama

┌────────────────────────────┐
│ Release notes for i3 v4.0 │
└────────────────────────────┘
This is the first release of the new major version of i3, v4.0. It has been a
long time since v3.ε was released (over one year). A lot has been happening
since then, we made 736 commits – compare that to the total number of 1664
commits for i3.
The reason for the high number of commits and long time for this release is the
big refactoring we have been doing. Instead of using several lists and a table
as data structures, we now use a single tree of containers. These containers
represent invisible entities like your X11 root window, your different monitors
and workspaces, but also visible entities like actual windows.
Using a tree has made a lot of things cleaner and easier – in the code *and* in
the user interface. Admittedly though, you will probably need a day or two to
get used to a few more advanced movement commands if you are used to v3.ε right
now.
┌────────────────────────────┐
│ New features │
└────────────────────────────┘
• In addition to the proper flex/bison based parser for the config file
introduced in 3.δ, we now also have a flex/bison parser for commands. What
this means is that we can have more human-readable, beautiful command names
instead of cryptic commands like 'f' for fullscreen or 'mh' for move left.
In fact, the commands for the aforementioned functions *are* 'fullscreen'
and 'move left'!
• You can now chain commands using ';' (a semicolon). One example for that is
'workspace 3 ; exec /usr/bin/urxvt' to switch to a new workspace and open a
terminal.
• You can specify which windows should be affected by your command by using
different criteria. A good example is '[class="Firefox"] kill' to get rid
of all Firefox windows.
• As the configuration file needs new commands (and a few options are
obsolete), you need to change it. To make this process a little bit easier
for you, this release comes with the script i3-migrate-config-to-v4.pl. Just
run it on your current config file and it will spit out a v4 config file to
stdout. To make things even better, i3 automatically detects v3 config files
and calls that script, so you never end up with a non-working config :).
• Similarly to the criteria when using commands, we now have a 'for_window'
configuration directive, which lets you automatically apply certain commands
to certain windows. Use it to set border styles per window, for example with
'for_window [class="XTerm"] border 1pixel'.
• Since dock clients (like dzen2) are now part of the layout tree (as opposed
to a custom data structure as before), it was easy to implement top and
bottom dock areas. Programs which properly specify the dock hint get placed
on the edge of the screen they request. i3bar has the -dtop and -dbottom
parameters, for example.
• The internal workspace bar is obsolete. Use i3bar instead.
• Resizing now works between all windows!
• Fullscreen now works for everything!
• Floating now works for everything!
• Your layout is now preserved when doing an inplace restart.
• When you have an error in your config file, a new program called i3-nagbar
will tell you so. It offers you two buttons: One to view the error in your
$PAGER and one to edit your config in your $EDITOR.
• The default config used key symbols (like 'bind Mod1+f fullscreen') instead
of key codes. If you use a non-qwerty layout, the program i3-config-wizard
can create a key symbol based config file based on your current layout. You
can also chose between Windows (Mod4) and Alt (Mod1) as your default
modifier. i3-config-wizard will automatically be started as long as you
don’t have a configuration file for i3.
• Custom X cursor themes are now supported.
• The RandR backend now respects the primary output.
• A wrong 'font' configuration in your config file will no longer make i3
exit. Instead, it will fall back to a different font and tell you about the
error in its log.
• The default split direction (whether a new window gets placed right next to
the current one or below the current one) is now automatically set to
horizontal if you have a monitor that is wider than high or vertical if you
a monitor which is higher than wide. This works great with rotated monitors.
• Sockets and temporary files are now placed in XDG_RUNTIME_DIR, if set (this
is used on systemd based systems).
• Tools like i3bar, i3-msg etc. use the I3_SOCKET_PATH property which is set
to the X11 root window, so you don’t have to configure your socket path
anywhere.
• The kill command kills single windows by default now. To kill a whole
application, use 'kill client'.
• IPC: Commands can now have custom replies. When the parser encounters an
error, a proper error reply is sent.
• There is now an 'exec_always' configuration directive which works like
'exec' but will also be run when restarting.

│ Future features │
└────────────────────────────┘
Our plans were big but our time and manpower is limited. Therefore, the
following features did not make it into this release. However, the foundation
is now in place and implementing them is possible, so stay tuned!
• Saving/Restoring specific parts of your layout
• Session saving
• Sticky windows

Release notes for i3 tree-pr1
-----------------------------
This is a PREVIEW RELEASE for the tree branch. It is *NOT* part of i3’s regular
releases and should *NOT* be packaged in the usual way for distributions.
Instead, provide a separate, unofficial package if possible.
The so called tree branch is the place where the next version of i3 is
developed. This time, we did a major code refactoring bringing many changes.
The idea is to use a tree as datastructure instead of separate lists (like one
for outputs, workspaces and a table for storing your window layout).
Quite a few advantages arise from this new data structure. The most prominent
ones will be a slightly different look and feel, the possibility to store your
layout and restore it later, correct resizing, a much cleaner command parser
and more little improvements.
As this is a preview release, some things are not working yet. Generally,
though, the core developers are using it already and think it’s good enough to
try it out. With this release, we want to gather feedback from you, so please
report any bugs you encounter in our bugtracker at http://i3.zekjur.net/bugs
What should be working in this release?
---------------------------------------
• Basic window management, navigation, moving
• Fullscreen mode, correct aspect ratio
• Stacked/Tabbed layout, floating mode
• Splitting (for fancy layouts), resizing
• Restarts, preserving the layout
• i3bar, get it from http://git.merovius.de/
If any of these features do not work (correctly), please file a bugreport.
What is not working in this release?
------------------------------------
• RandR changes (i3 needs to be restarted)
• Assignments
• Configfile compatibility
• Workspace switching is sometimes not working. If you find a pattern, please
report it.
• There are still some bugs in resizing. Please report!

Looks at existing or new windows and decides whether to manage them. If so, it
reparents the window and inserts it into our data structures.
src/resize.c::
Contains the functions to resize columns/rows in the table.
src/match.c::
A "match" is a data structure which acts like a mask or expression to match
certain windows or not. For example, when using commands, you can specify a
command like this: [title="*Firefox*"] kill. The title member of the match
data structure will then be filled and i3 will check each window using
match_matches_window() to find the windows affected by this command.

Manages the most important internal data structure, the design table.
src/move.c::
Contains code to move a container in a specific direction.
src/output.c::
Functions to handle CT_OUTPUT cons.
src/randr.c::
The RandR API is used to get (and re-query) the configured outputs (monitors,
…).
src/render.c::
Renders the tree data structure by assigning coordinates to every node. These
values will later be pushed to X11 in +src/x.c+.

src/x.c::
Transfers our in-memory tree (see +src/render.c+) to X11.
src/xcb.c::
Contains wrappers to use xcb more easily.
src/xcursor.c::
XCursor functions (for cursor themes).
src/xinerama.c::
(Re-)initializes the available screens and converts them to virtual screens
(see below).

/////////////////////////////////////////////////////////////////////////////////
== Moving containers
The movement code is pretty delicate. You need to consider all cases before
making any changes or before being able to fully understand how it works.
=== Case 1: Moving inside the same container
The reference layout for this case is a single workspace in horizontal
orientation with two containers on it. Focus is on the left container (1).
[width="15%",cols="^,^"]
|========
| 1 | 2
|========
When moving the left window to the right (command +move right+), tree_move will
look for a container with horizontal orientation and finds the parent of the
left container, that is, the workspace. Afterwards, it runs the code branch
commented with "the easy case": it calls TAILQ_NEXT to get the container right
of the current one and swaps both containers.
=== Case 2: Move a container into a split container
The reference layout for this case is a horizontal workspace with two
containers. The right container is a v-split with two containers. Focus is on
the left container (1).
[width="15%",cols="^,^"]
|========
1.2+^.^| 1 | 2
| 3
|========
When moving to the right (command +move right+), i3 will work like in case 1
("the easy case"). However, as the right container is not a leaf container, but
a v-split, the left container (1) will be inserted at the right position (below
2, assuming that 2 is focused inside the v-split) by calling +insert_con_into+.
+insert_con_into+ detaches the container from its parent and inserts it
before/after the given target container. Afterwards, the on_remove_child
callback is called on the old parent container which will then be closed, if
empty.
Afterwards, +con_focus+ will be called to fix the focus stack and the tree will
be flattened.
=== Case 3: Moving to non-existant top/bottom
Like in case 1, the reference layout for this case is a single workspace in
horizontal orientation with two containers on it. Focus is on the left
container:
[width="15%",cols="^,^"]
|========
| 1 | 2
|========
This time however, the command is +move up+ or +move down+. tree_move will look
for a container with vertical orientation. As it will not find any,
+same_orientation+ is NULL and therefore i3 will perform a forced orientation
change on the workspace by creating a new h-split container, moving the
workspace contents into it and then changing the workspace orientation to
vertical. Now it will again search for parent containers with vertical
orientation and it will find the workspace.
This time, the easy case code path will not be run as we are not moving inside
the same container. Instead, +insert_con_into+ will be called with the focused
container and the container above/below the current one (on the level of
+same_orientation+).
Now, +con_focus+ will be called to fix the focus stack and the tree will be
flattened.
=== Case 4: Moving to existant top/bottom
The reference layout for this case is a vertical workspace with two containers.
The bottom one is a h-split containing two containers (1 and 2). Focus is on
the bottom left container (1).
[width="15%",cols="^,^"]
|========
2+| 3
| 1 | 2
|========
This case is very much like case 3, only this time the forced workspace
orientation change does not need to be performed because the workspace already
is in vertical orientation.
=== Case 5: Moving in one-child h-split
The reference layout for this case is a horizontal workspace with two
containers having a v-split on the left side with a one-child h-split on the
bottom. Focus is on the bottom left container (2(h)):
[width="15%",cols="^,^"]
|========
| 1 1.2+^.^| 3
| 2(h)
|========
In this case, +same_orientation+ will be set to the h-split container around
the focused container. However, when trying the easy case, the next/previous
container +swap+ will be NULL. Therefore, i3 will search again for a
+same_orientation+ container, this time starting from the parent of the h-split
container.
After determining a new +same_orientation+ container (if it is NULL, the
orientation will be force-changed), this case is equivalent to case 2 or case
4.
=== Case 6: Floating containers
The reference layout for this case is a horizontal workspace with two
containers plus one floating h-split container. Focus is on the floating
container.
TODO: nice illustration. table not possible?
When moving up/down, the container needs to leave the floating container and it
needs to be placed on the workspace (at workspace level). This is accomplished
by calling the function +attach_to_workspace+.
== Click handling
Without much ado, here is the list of cases which need to be considered:
* click to focus (tiling + floating) and raise (floating)
* click to focus/raise when in stacked/tabbed mode
* floating_modifier + left mouse button to drag a floating con
* floating_modifier + right mouse button to resize a floating con
* click on decoration in a floating con to either initiate a resize (if there
is more than one child in the floating con) or to drag the
floating con (if it’s the one at the top).
* click on border in a floating con to resize the floating con
* floating_modifier + right mouse button to resize a tiling con
* click on border/decoration to resize a tiling con
== Gotchas
* Forgetting to call `xcb_flush(conn);` after sending a request. This usually

orientation (string)::
Can be either "none" (for non-split containers), "horizontal" or
"vertical".
percent (float)::
The percentage which this container takes in its parent. A value of
+null+ means that the percent property does not make sense for this
container, for example for the root container.
rect (map)::
The absolute display coordinates for this container. Display
coordinates means that when you have two 1600x1200 monitors on a single
X11 Display (the standard way), the coordinates of the first window on
the second monitor are +{ "x": 1600, "y": 0, "width": 1600, "height":
1200 }+.
window_rect (map)::
The coordinates of the *actual client window* inside its container.
These coordinates are relative to the container and do not include the
window decoration (which is actually rendered on the parent container).
So, when using the +default+ layout, you will have a 2 pixel border on
each side, making the window_rect +{ "x": 2, "y": 0, "width": 632,
"height": 366 }+ (for example).

The original geometry the window specified when i3 mapped it. Used when
switching a window to floating mode, for example.

Whether this container (window or workspace) has the urgency hint set.
focused (bool)::
Whether this container is currently focused.

which are not relevant for the type of the node. Otherwise, the example would
be by far too long (it already is quite long, despite showing only 1 window and

Tree branch: Migrating
======================
Michael Stapelberg <michael+i3@stapelberg.de>
November 2010
== Introduction
The tree branch (referring to a branch of i3 in the git repository) is the new
version of i3. Due to the very deep changes and heavy refactoring of the source
source, we decided to develop it in a separate branch (instead of using the
next/master-branch system like before).
== Current status
Currently, the code is mostly working. Some of the i3 core developers have been
using the tree branch version for a few weeks now. So, if you are eager to try
out the new features and help us find bugs, give it a try!
At the same time, a word of warning is appropriate: This version of i3 might
crash unexpectedly, so please be careful with important data (do not work for
two days without saving…).
== Getting the latest tree branch version
Check out the latest version:
---------------------------------------------
$ git clone -b tree git://code.stapelberg.de/i3
---------------------------------------------
Then build and install it (has the same dependencies as the latest stable i3
version):
-----------------------------
$ cd i3
$ make
$ sudo cp i3 /usr/bin/i3-tree
-----------------------------
…and execute +i3-tree+ instead of +i3+ in your Xsession.
*IMPORTANT:* Please note that configuration file compatibility is not yet done.
So, make sure you use/customize the provided +i3.config+ file.
== Tree
The most important change and reason for the name is that i3 stores all
information about the X11 outputs, workspaces and layout of the windows on them
in a tree. The root node is the X11 root window, followed by the X11 outputs,
then workspaces and finally the windows themselve. In previous versions of i3
we had multiple lists (of outputs, workspaces) and a table for each workspace.
That approach turned out to be complicated to use (snapping), understand and
implement.
=== The tree consists of Containers
The building blocks of our tree are so called +Containers+. A +Container+ can
host a window (meaning an X11 window, one that you can actually see and use,
like a browser). Alternatively, it could contain one or more +Containers+. A
simple example is the workspace: When you start i3 with a single monitor, a
single workspace and you open two terminal windows, you will end up with a tree
like this:
image::tree-layout2.png["layout2",float="right"]
image::tree-shot4.png["shot4",title="Two terminals on standard workspace"]
=== Orientation and Split Containers
[[OrientationSplit]]
It is only natural to use so-called +Split Containers+ in order to build a
layout when using a tree as data structure. In i3, every +Container+ has an
orientation (horizontal, vertical or unspecified). So, in our example with the
workspace, the default orientation of the workspace +Container+ is horizontal
(most monitors are widescreen nowadays). If you change the orientation to
vertical (+Alt+v+ in the default config) and *then* open two terminals, i3 will
configure your windows like this:
image::tree-shot2.png["shot2",title="Vertical Workspace Orientation"]
An interesting new feature of the tree branch is the ability to split anything:
Let’s assume you have two terminals on a workspace (with horizontal
orientation), focus is on the right terminal. Now you want to open another
terminal window below the current one. If you would just open a new terminal
window, it would show up to the right due to the horizontal workspace
orientation. Instead, press +Alt+v+ to create a +Vertical Split Container+ (to
open a +Horizontal Split Container+, use +Alt+h+). Now you can open a new
terminal and it will open below the current one:
image::tree-layout1.png["Layout",float="right"]
image::tree-shot1.png["shot",title="Vertical Split Container"]
unfloat::[]
You probably guessed it already: There is no limit on how deep your hierarchy
of splits can be.
=== Level up
Let’s stay with our example from above. We have a terminal on the left and two
vertically split terminals on the right, focus is on the bottom right one. When
you open a new terminal, it will open below the current one.
So, how can you open a new terminal window to the *right* of the current one?
The solution is to use +level up+, which will focus the +Parent Container+ of
the current +Container+. In this case, you would focus the +Vertical Split
Container+ which is *inside* the horizontally oriented workspace. Thus, now new
windows will be opened to the right of the +Vertical Split Container+:
image::tree-shot3.png["shot3",title="Level Up, then open new terminal"]
== Commands
The authoritive reference for commands is +src/cmdparse.y+. You can also find
most commands in +i3.config+. Here comes a short overview over the important
commands:
=== Manipulating layout
-------------------------------
layout <default|stacked|tabbed>

---------------------
move workspace <name>
---------------------
-------------------------------------
bindsym Mod1+Shift+1 move workspace 1
bindsym Mod1+Shift+2 move workspace 2
…

---------------------------
border <normal|none|1pixel>
---------------------------
=== Changing container mode
-----------------------------
mode <tiling|floating|toggle>
-----------------------------
== The rest
What is not mentioned here explicitly is either unchanged and can be read in
the http://i3.zekjur.net/docs/userguide.html[i3 User’s Guide] or it is not yet
implemented.

*
* Let’s start from the biggest to the smallest:
*
* - An Output is a physical output on your graphics driver. Outputs which
* are currently in use have (output->active == true). Each output has a
* position and a mode. An output usually corresponds to one connected
* screen (except if you are running multiple screens in clone mode).
*
* - Each Output contains Workspaces. The concept is known from various
* other window managers. Basically, a workspace is a specific set of
* windows, usually grouped thematically (irc, www, work, …). You can switch
* between these.
*
* - Each Workspace has a table, which is our layout abstraction. You manage
* your windows by moving them around in your table. It grows as necessary.
*
* - Each cell of the table has a container, which can be in default or
* stacking mode. In default mode, each client is given equally much space
* in the container. In stacking mode, only one client is shown at a time,
* but all the titlebars are rendered at the top.
*
* - Inside the container are clients, which is X11-speak for a window.

i3-nagbar(1)
============
Michael Stapelberg <michael+i3@stapelberg.de>
v4.0, July 2011
== NAME
i3-nagbar - displays an error bar on top of your screen
== SYNOPSIS
i3-nagbar -m 'message' -b 'label' 'action'
== DESCRIPTION
i3-nagbar is used by i3 to tell you about errors in your configuration file
(for example). While these errors are logged to the logfile (if any), the past
has proven that users are either not aware of their logfile or do not check it
after modifying the configuration file.
== EXAMPLE
------------------------------------------------
i3-nagbar -m 'You have an error in your i3 config file!' \
-b 'edit config' 'xterm $EDITOR ~/.i3/config'
------------------------------------------------
