fixes#1835
This commit improves the translation of keysyms to keycodes by loading
keymaps using libxkbcommon-x11 and using libxkbcommon for figuring out
the keymap, depending on each keybinding’s modifiers. This way, the
upper layers of complex layouts are now usable with i3’s bindsym
directive, such as de_neo’s layer 3 and higher.
Furthermore, the commit generalizes the handling of different XKB
groups. We formerly had support only for two separate groups, the
default group 1, and group 2. While Mode_switch is only one way to
switch to group 2, we called the binding option Mode_switch. With this
commit, the new names Group1, Group2 (an alias for Mode_switch), Group3
and Group4 are introduced for configuring bindings. This is only useful
for advanced keyboard layouts, such as people loading two keyboard
layouts and switching between them (us, ru seems to be a popular
combination).
When grabbing keys, one can only specify the modifier mask, but not an
XKB state mask (or value), so we still dynamically unbind and re-bind
keys whenever the XKB group changes.
The commit was manually tested using the following i3 config:
bindsym Group4+n nop heya from group 4
bindsym Group3+n nop heya from group 3
bindsym Group2+n nop heya from group 2
bindsym n nop heya
bindsym shift+N nop explicit shift binding
bindsym shift+r nop implicit shift binding
bindcode Group2+38 nop fallback overwritten in group 2 only
bindcode 38 nop fallback
…with the following layout:
setxkbmap -layout "us,ua,ru,de" -variant ",winkeys,,neo" \
-option "grp:shift_caps_toggle,grp_led:scroll" \
-model pc104 -rules evdev
By default (xkb group 1, us layout), pressing “n” will result in the
“heya” message appearing. Pressing “a” will result in the “fallback”
message appearing. “j” is not triggered.
By pressing Shift+CapsLock you switch to the next group (xkb group 2, ua
layout). Pressing “a” will result in the “fallback overwritten in group
2 only” message, pressing “n” will still result in “heya”. “j” is not
triggered.
In the next group (xkb group 3, ru layout), pressing “a” will result in
the “fallback” message again, pressing “n” will result in “heya”,
“j” is not triggered.
In the last group (xkb group 4, de_neo layout), pressing “a” will still
result in “fallback”, pressing “n” will result in “heya”, pressing “j”
will result in “heya from group 4”.
Pressing shift+n results in “explicit shift binding”, pressing shift+r
results in “implicit shift binding”. This ensures that keysym
translation falls back to looking at non-shift keys (“r” can be used
instead of ”R”) and that the order of keybindings doesn’t play a role
(“bindsym n” does not override “bindsym shift+n”, even though it’s
specified earlier in the config).
The fallback behavior ensures use-cases such as ticket #1775 are still
covered.
Only binding keys when the X server is in the corresponding XKB group
ensures use-cases such as ticket #585 are still covered.
With commit c738b2e454 we changed i3 so
that the default keybindings can be used when ISO_Next_Group is enabled,
but bindings which explicitly use Mode_switch have precedence. This
behavior required the use of bindcode instead of bindsym.
With this commit, when switching from group 1 to group 2 using
ISO_Next_Group, i3 will re-translate all keybindings (looking at column
2/3, regardless of whether the keybinding itself specifies Mode_switch)
and re-grab them.
That way, the keybinding “bindsym $mod+x nop foo” will work when
pressing $mod+x without Mode_switch and when pressing the corresponding
$mod+x (different key) with Mode_switch. A binding such as “bindsym
Mode_switch+$mod+x nop bar” will still have precedence.
The intention here is to make bindsym keybindings work well with dual
keyboard layouts (such as {dvorak, us} or {us, ru}), so that users can
switch between groups and still have their (logical) keybindings behave
the same way.

Do not log an XCB_MOTION_NOTIFY event in handlers.c because this
clutters the log.
Only log in the motion notify handler if something important happens.
When a window receives a _NET_ACTIVE_WINDOW message, it can steal the focus. This may not be preferable to all users.
With this directive, the user can choose from one of the following:
1) 'smart' - focus the container if its workspace is visible, otherwise set the urgency flag (default)
2) 'urgent' - always set the urgency flag, do not steal focus
3) 'focus' - always switch focus, never set the urgency hint
4) 'none' - ignore the request entirely (do not switch focus, nor set the urgency hint)

Handle changes to the property _NET_WM_STRUT_PARTIAL by reallocating
screen space in the dock area when the dock client requests a new
position.
This will allow changes to the bar config directive `position` to be
effective on the `reload` command.

Not quite sure why there are so many differences. Perhaps we’ve gotten
out of the habit of running clang-format after every change.
I guess it’d be best to have a travis hook that runs clang-format for us
and reports any problems on pull requests.
Add support for the _NET_WM_MOVERESIZE client message. This message
enables clients to initiate window moving or resizing. Toolkits like
Gtk3 use this message when the user drags a client-side decorated window
by its title bar. When Gtk detects that the window manager does not
support this client message, it uses a slow fallback implementation.

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

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.)
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.
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.
Allow client requests of type _NET_ACTIVE_WINDOW to switch workspaces if
they indicate they are a pager. Otherwise, set the urgency hint on that
con to indicate that something happened.
This allows task switchers like skippy-xd to work properly.

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
Reply to _NET_REQUEST_FRAME_EXTENTS by settings _NET_FRAME_EXTENTS
property of the window to widths of the respective borders added by i3.

This ClientMessage can be used to estimate how big the window will be
before opening it. Java always sends the ClientMessage and checks the
atom that should be set by the window manager, but it seems that the
fallback code path has a race condition.
Let’s see if the situation gets better with this change. I have been
running this patch for about two weeks and have not seen any issues with
it.

This commit only goes to “next” because I am not sure whether it
actually makes things better in all cases and want to give it some
testing first.
There was no documented reason behind using the
proportional_{width,height} variables, so I suppose that code was just
stupidity on my part (it was written merely a month after I started this
project in 2009).
fixes#1032
_NET_WM_STATE_DEMANDS_ATTENTION indicates that some action in or with
the window happened. It's a weaker hint than urgency flag of WM_HINTS,
but some applications and almost all Qt applications use it instead of
WM_HINTS' urgency flag (one example is Skype).
