I think this is not a good feature to have. It shouldn’t be necessary
for a tiling window manager that explicitly discourages the use of
floating windows.

i3 processes changes to WM_CLASS by updating the cached property and
running assignments. This allows the property to be used in criteria
selection.

When a window becomes managed, explicitly set the current border width
to the default instead of relying on the default value of -1 to apply
the correct value.
Now that there are two different kinds of default borders, a border
width value of -1 is ambiguous. This can lead to different border widths
effectively being applied when the container changes from tiling to
floating, which is surprising behavior.
This commit extends behavior introduced in this commit to normal
borders:

Explicitly set current border width when BS_PIXEL
fixes#1304
Users can specify a command to run when a button was pressed on i3bar to
override the default behavior. Currently only the mouse wheel buttons
are supported. This is useful for disabling the scroll wheel action or
running scripts that implement custom behavior for these buttons.
Example:
bar {
wheel_up_cmd nop
wheel_down_cmd exec ~/.i3/scripts/custom_wheel_down
}

This reverts commit b109b1b20d.
Turns out the change in behavior was unexpected by a number of users, so
let’s revert it and make those users that want this behavior configure
it explicitly.
Sorry for the back-and-forth here.
When a window becomes managed, if the config specifies a pixel border
style, explicitly set the current border width so it does not change
when the container changes from tiling to floating.

When calculating the geometry of a floating window with motif hints that
specify a border style, take into account that this window will have a
different border style when calculating its position with
floating_enable() when the window becomes managed.
A nice side effect of this is that users can override motif hints with
`new_float` config directives when they are specified other than
`normal`.

A window may become unmapped on manage when an assignment command unmaps
the window, such as moving it to the scratchpad or killing it.
This can cause i3 focus to be an unmapped window and different than X
focus which can lead to complications

If a `workspace {N}` or `move to workspace {N}` command is given with N
as a plain number, the workspace of this number is selected for the
context of the command if one exists and there is no workspace with a
name that exactly matches N.
A container selected with criteria should be moved with the `move
[direction]` command, instead of this command always acting on the
focused container.
This removes our last dependency on Xlib! :)
(Okay, an Xlib dependency still comes in through other libraries that we
link against, but it’s not us. Our code is simpler by this change and
uses one less connection to X11.)
A configured mouse binding (for example `bindsym button3 kill`) runs
its command when the mouse button is pressed over parts of a container.
If the binding has no modifer, it will only run when the button is
clicked on the window titlebar.
Otherwise if the binding has a modifier, it will run over the titlebar
or any part of the contained window.

Since managing a window happens on a MapNotify (which is absent from this
list), the window cannot accept input focus, so we should not try to focus
the window at all.
Fixes an issue with xfce4-notifyd which (correctly) declines focus when
we send WM_TAKE_FOCUS, which puts i3 in a state where i3 focus and X
focus are different when a notification appears.

We interpret this property as the number of noninternal workspaces.
This should be the last commit that formats a big bunch of files. From
here on, whenever I merge patches, I’ll run clang-format like described
in the title.
This has multiple effects:
1) The i3 codebase is now consistently formatted. clang-format uncovered
plenty of places where inconsistent code made it into our code base.
2) When writing code, you don’t need to think or worry about our coding
style. Write it in yours, then run clang-format-3.5
3) When submitting patches, we don’t need to argue about coding style.
The basic idea is that we don’t want to care about _how_ we write the
code, but _what_ it does :). The coding style that we use is defined in
the .clang-format config file and is based on the google style, but
adapted in such a way that the number of modifications to the i3 code
base is minimal.
I consider this behavior broken and not respecting the standard, but it
happens in real life, and it’s better for i3 to not busy-loop in such a
situation :).
fixes#1259
When `focus_follows_mouse` option is on, prevent an uneeded render on
pointer enter when the con is already focused.
This pointer enter might be caused by entering a window decoration of an
already-focused container.
This extra render can cause concurrency issues when focus is set
asynchronously with WM_TAKE_FOCUS.

This fixes a bug that would not update _NET_ACTIVE_WINDOW when focus
changed to an i3 container without a window such as a branch or
workspace content container.
parse_command returns a struct that contains useful information about
the result of a command as a whole (instead of the intermediate
representation used during parsing).
parse_command now requires the caller to allocate the yajl_gen used for
generating a json reply. This is passed as the second parameter to
parse_command. If NULL is passed, no json reply will be generated.
This patch adds a new configuration option "mouse_warping [output|none]".
When mouse warping is disabled, mouse cursor does not jump to middle of current
screen when changing workspaces between multiple outputs. This introduces a
"special" cursor state, where focus is in one window and cursor on another.
Useful for eg. scrolling a web page with mouse wheel while typing into another
window on keyboard.
Workspace assignments with bare numbers assign all workspaces with that
number to the specified output.
Workspace assignment by number is overridden by workspace assignment by
name.
Change the name of structs CommandResult and ConfigResult to
CommandResultIR and ConfigResultIR to show they are an intermediate
representation used during parsing.
Floating windows already had their own border style, but the width was
the same for all windows.
The configuration directives 'new_window' and 'new_float' can now be
used simultaneously to have different border widths for floating and
tiled windows.
fixes#1244
Implement the configuration option within the bar config directive for
custom workspace numbers with the directive `strip_workspace_numbers
yes`.
This directive strips the workspace name of the number prefix and
delimiter. When the workspace name consists only of the number, it will
default to show the number.
For example:
* "2:5" -> "5"
* "4:$" -> "$"
* "8" -> "8"
This allows customization of i3bar for alternate ordering of workspaces
which has a legitimate use for alternate keyboard layouts such as
Dvorak.
fixes#1131
Allow client requests of type _NET_ACTIVE_WINDOW to switch workspaces if

Change the primary binding accessor to `get_binding_from_xcb_event`.
This function gets a binding from a generic xcb event of type KeyPress,
KeyRelease, ButtonPress, or ButtonRelease by determining the input type
(keyboard or mouse), the modifiers pressed from the filtered event
`state`, managing the proper fall back in case mode switch is enabled,
and finally querying the bindings for a binding that matches the event.
The logic of querying keyboard bindings is not intended to be altered by
this change.
The general accessor has been slightly modified to work with mouse
bindings and made private because it is only used in bindings.c

The _NET_CLIENT_LIST property of the root window:
> These arrays contain all X Windows managed by the Window Manager.
Dock clients are not managed windows, so they should not be included in
_NET_CLIENT_LIST or _NET_CLIENT_LIST_STACKING.
Workspaces won't work properly if they start with "__", so reserve that
namespace altogether. Disallow renaming workspaces to reserved namespace
and using reserved namespace in configuration.
Fixes#1209.
The fullscreen_mode event is a window with the "change" property set to
"fullscreen_mode". This event should be emitted whenever a window enters
or exits fullscreen mode.
This event can be used to turn off dpms off when a window is fullscreen
or display the fullscreen container name in the status line for
instance.
Send all the options in the bar block on the barconfig_update event.
This will eventually allow for dynamically updating bar colors with the
`reload` command.
Do not handle click events on dock clients because they are not managed
windows. Dock clients are responsible for sending the message to i3 to
focus a workspace if that is appropriate. i3bar now sends the message to
focus the correct workspace when that is appropriate.
Otherwise, it could interfere with the dock clients own click handling,
which could be an action to focus a different workspace than i3 had
assumed, such as would be the case with a workspace widget.
The log message at the top of ipc_send_window_event would segfault when
no xcb window is present, such as for a split container.
The log now shows the con id which is more relevant anyway.
If a `bindsym` config directive specifies a symbol beginning with
"button", the binding will be given the type B_MOUSE for the indicated
button number.
Example:
bindsym $mod+button2 exec echo 'button two'
This will be interpreted as having input code (now `keycode`) 2 and type
B_MOUSE.
The mechanism to find and run mouse bindings on mouse events is not
implemented.
When checking the window type for a resize command, first check to see
if the window property is null before checking whether or not it is a
dock window. The window may be null in the case it is a branch
container.

Adds the timestamp parameter to send_take_focus to avoid the dangerous
use of a global variable.
This memory leak is related to matching on con_id or matching when the
container has a null window. In that case, windows that do not match
would leak the owindow struct.
This memory leak is associated with matching by a criteria that uses a
regular expression. Without freeing a regex before calling match_init,
it will definitely be lost.
cmd_resize does not implement a method to resize dock clients.
A command like `[instance=".*"] resize grow width 160 px or 16 ppt`

This patch fixes ticket #1168 to extend the window IPC event mechanism
to send IPC events for window focus and title changes. The newly added
window events use the same format as the already established "new"
event.
Specifically this patch:
* Moves the ipc_send_window_event() function from src/manage.c into
src/ipc.c and adds an argument for the change property of the event
* Updates src/manage.c to use the new function signature. To ensure
that the "new" event does not send the same event data as the
"focus" event, setting focus now happens after the "new" event
has been sent
* Adds IPC focus event notification to src/x.c. To workaround a problem
during window close when accessing the window name, a function has been
added to query whether a window is actually attached to its parent. To
avoid obsolete focus notification, a new field has been added to keep
track of the focus without any interference by the click handling
* Adds IPC title event notification to src/handlers.c. To avoid
obsolete title notification, a function has been added to determine
whether a window title has actually changed
* Updates the IPC documentation to include the new events
* Updates testcases/t/205-ipc-windows.t to include the "focus" event
in order to ensure the correct event sequence
* Adds two new unit tests, b/testcases/t/219-ipc-window-focus.t and
b/testcases/t/220-ipc-window-title.t to ensure proper "focus" and
"title" events
The X11 protocol description states:
The window the event is reported with respect to is called the event
window. The event window is found by starting with the source window
and looking up the hierarchy for the first window on which any client
has selected interest in the event.
For the case of urxvt with URxvt.internalBorder > 0, urxvt sets up a
subwindow for its actual contents that is placed “in the middle” of the
urxvt window. In terms of the X11 protocol, the source window is urxvt’s
window, but urxvt does not select ButtonPress events for that.
Therefore, X11 will go up in the hierarchy and deliver the event to i3
for i3’s window decoration, even though this was not actually a click on
the decoration, but into the managed window.
Therefore, we check whether child != XCB_NONE for clicks on window
decorations and then handle them as a click inside the window.

When the _MOTIF_WM_HINTS property of a window specifies it should have
no title bar, or no decorations at all, respond by setting the border
style of that container to BS_PIXEL or BS_NONE respectively.
This comes from the old Motif window manager. It was originally intended
to specify exactly what sort of decorations a window should have, and
exactly what sort of user input it should respond to. The EWMH spec
intended to replace Motif hints with _NET_WM_WINDOW_TYPE, but it is
still in use by popular widget toolkits such as GTK+ and Java AWT.
i3's implementation simply mirrors Gnome's Metacity. Official
documentation of this hint is nowhere to be found.

Change the behavior of movement into a branch with respect to the
position the moving con will be placed within the branch when the

The correct position is determined by the direction of movement or the
position of the focused-inactive container within the branch.
If the direction of movement is the same as the orientation of the
branch container, append or prepend the container to the branch in the
obvious way. If the movement is to the right or downward, insert the
moving container in the first position (i.e., the leftmost or top
position resp.) If the movement is to the left or upward, insert the
moving container in the last position (i.e., the rightmost or bottom
position resp.)
If the direction of movement is different from the orientation of the
branch container, insert the container into the branch after the
focused-inactive container.
fixes#1060
When `focus_follows_mouse` configuration option is disabled, do not warp
the pointer when focus changes outputs after rendering.
Rationale: this option is meant to be disabled by users who have a setup
where the mouse is usually in the way. These users tend to move the
mouse to a corner or use a utility to hide the pointer when it is not
active. When this user switches focus between outputs, the mouse is
placed in the center of the screen.
This is clearly against the spirit of disabling `focus_follows_mouse`.
Disabling this option now implies disabling "mouse follows focus".
When the user initiates a drag resize, draw the resize bar on the border
of the two involved containers and snap the pointer.
This solution produces cleaner code than the former approach where the
caller obfuscated the click coordinates of the event. This may confuse
someone expecting a true button press event.
Fixes an issue where the resize cursor is not shown when the resize bar
is clicked until the user begins to drag the mouse.
Fixes an issue where focus is not properly updated after the drag is
complete when `focus_follows_mouse' option is set, leaving the pointer
in an unfocused window in some cases.
Fixes an issue where the resize bar may jump a few pixels when the mouse
is first moved.
(Thanks to pbos for suggesting this fix and providing an example
implementation)
This is done by installing a new check watcher that replaces the main
X11 event handler and calling ev_run with EVRUN_ONCE until the dragging
loop left state DRAGGING.
With this commit, other handlers, most notably the redraw handler for
placeholder windows, get a chance to run when dragging (placeholder!)
windows around.
state->initial is set to false before calling x_push_node() since we
began pushing the window stack before pushing changes. Therefore, the
condition could never be true.

The commit title is fairly technical, so I’ll try to explain.
Recently, users of GDM3 (I’m sure) and LightDM (I think) have reported
that when switching to a new workspace, the contents of the previous
workspace are still visible. i3bar updates, though, so it is the X11
root window which is not being updated here.
When using GDM3, X11 will be started with -background none, and no
background pixmap or pixel is set. Then, apparently,
gnome-settings-daemon will display a fade animation from whatever is
currently on the window to the destination contents. I think this is to
avoid flickering when logging in, which would occur when just setting a
specific background pixmap or pixel.
So, this commit will, when i3 starts first (not on restarts), copy the
contents of the X11 root window (typicall a grey background, at least on
my machine with GDM3) into a pixmap and set that pixmap as background
pixmap. That way, the content will be preserved and one has a
background, instead of what is perceived as a bug :).
This commit has some chance of breakage, so I’m prepared to revert it
unless we can figure out the issues and roll forward.
Every container 'above' (in the hierarchy) the workspace content should
not be closed when the last child was removed.
Add a check for output content containers and do not handle them. These
cons are at the root of the output container with dockarea siblings.
They may be run through this callback when an output is killed with
RandR.
Fixes an issue that caused content cons to become urgent when the output
is killed with RandR.

This removes code duplication, which will be useful for a subsequent
commit.
Furthermore, we now don’t open X11 connections unnecessarily in some
corner cases.
When 'move <direction>' is issued in the context of a container that
borders a workspace, and there is no suitable place within this
workspace for which this container can move, move the container to the
closest output in this direction instead.
Add DRAG_ABORT to enum drag_result_t. DRAG_ABORT will indicate the drag
operation cannot be completed.
Return DRAG_ABORT on UnmapNotify, or when the keyboard or pointer cannot
be grabbed.
Add DRAGGING to return value for drag_result_t. DRAGGING is used
internally by drag_pointer to indicate the drag is in progress.
Change DRAG_CANCEL to DRAG_REVERT to clarify the distinction between
"abort" and "revert/cancel" actions.
Fixes an issue that caused i3 to crash when a user is dragging or
resizing a floating window that becomes destroyed.

i3 current behavior hides the binding mode indicator when
workspace buttons are disabled.
This patch adds a new configuration for i3bar called
'binding_mode_indicator' which acts like the workspace_buttons.
It is now possible to configure i3bar to hide the
workspace buttons and keep showing the binding mode indicator.
This should make the hide workspace buttons configuration
more convenient for those who are heavily using binding
modes.
Default value for binding_mode_indicator is true.
If the currently focused window is in fullscreen mode, and a new window
