This tool is similar to xtrace in usage in that it intercepts traffic to
the X server. The motivating feature for writing the tool is its ability
to inject prepared reply messages instead of the server’s reply. In
this particular case, we’ll inject a RRGetMonitors reply to test i3’s
RandR 1.5 code paths.
The added testcase is a noop for now, but with the code that’s lingering
in the randr15 branch, i3 does actually detect monitors as per the
injected reply:
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:618 -
RandR 1.5 available, querying monitors
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:628 -
1 RandR monitors found (timestamp 0)
2016-11-20 21:10:05 - randr.c:__randr_query_outputs:646 -
name DP3, x 0, y 0, width 3840 px, height 2160 px, width 520 mm,
height 290 mm, primary 1, automatic 1
This is preparation work for issue #1799
We call scratchpad_show() on _NET_ACTIVE_WINDOW requests if the request
came from a pager. This is consistent with the i3 »focus« command because
we assume the user requested to see the window, so we do the only
sensible thing.
fixes#2455
Before this commit, i3 only compared the user-specified modifiers and
incorrectly ignored the resolved modifiers (such as the numlock
fallback).
While at it, also fix the testcase which treated numlock as a momentary
modifier, whereas it really is a latched modifier.
fixes#2418
Previously, we always discarded the NumLock bit when looking up key
bindings for key press events, and we always grabbed every keycode with
and without the NumLock modifier.
With this commit, the NumLock bit is no longer discarded: since the
previous commit 3bd5e6e5c8 we can
correctly look up key bindings with/without the NumLock bit, as both
variants are stored in |keycodes_head|.
Further, before adding the NumLock fallback (resulting in grabbing the
keycode with the NumLock modifier), we now check whether the key has the
same meaning when NumLock is enabled. This correctly distinguishes the
KP_End vs. KP_1 case, i.e. one can now use the following key bindings:
# No longer accidentally triggered when pressing KP_1.
bindsym KP_End nop KP_End
# Properly distinguished now:
bindsym KP_End nop KP_End
bindsym Mod2+KP_1 nop KP_1

Use case:
* When managing multiple terminals in a workspace, the borders makes it easier
to know where the focus is, but when there is only one it's obvious where the
focus is.
* When there's only a web browser for example, the borders are actually counter-
productive since it makes clicking a side scrollbar or a tab a bit harder (if I
smash my cursor to the side or the top of the workspace, I have to move it in
the other direction by just a few pixels to be able to grab it)
Behaviour:
* No borders when there's a single window in a workspace
* Borders when there are multiple windows in a workspace
fixes#2188
This patch introduces a new 'set_from_resource' config directive which
allows defining a variable by retrieving its value from the X resource
database. This avoids having to configure a color scheme in multiple
files. The directive takes an additional fallback value which is used
in case the resource cannot be found or during config validation where
no X connection is available.
Furthermore, this patch includes the following changes:
- If the same variable is defined twice, we now properly overwrite the
value of the assignment rather than inserting two variable definitions
with the same key.
- We now depend on xcb-util-xrm to query the resource.
- Increase the buffer size for variable / resource assignments.
fixes#2130
With this change, multi-monitor presentations (e.g. as implemented by
LibreOffice Impress) work out of the box. Previously, one had to move
the presentation windows to the right outputs oneself.
If a user reloads the config while in some binding mode, the binding mode
will revert to the default, but no event will ever be fired, causing a
broken i3bar mode display.
This patch explicitly reverts to the default binding mode before reloading
the config. We reload rather than switch to the binding mode after having
reloaded the config because there's no guarantee that mode will even still
exist.
fixes#2228
This patch correctly determines the previously focused workspace on the
target output when moving a workspace to another output. Before, we used
nodes_head for this, which will not actually return the previously focused
workspace, but just the first workspace on that output. Hence, we now use
focus_head instead.
This bug was introduced all the way back in 1e143fea when the feature of
moving workspaces to another output was first implemented.
fixes#2229
This patch introduces a proprietary atom I3_FLOATING_WINDOW which will be
set and maintained for floating windows and removed on tiling containers.
This allows users to select on this atom, e.g., in their compositor
configuration or in utility scripts (without using the IPC).
fixes#2223
This is essentially a revert of daf00a9 which introduced a mechanism
to float workspace containers by wrapping all children into a new
container and floating it.
This caused a bug and there's no good reason (anymore) to allow doing
this in the first place as we don't support floating nested containers.
fixes#2166
We already claim _NET_WM_DESKTOP support in _NET_SUPPORTED since around 2009,
but haven't actually done anything with it. However, especially pagers like
gnome-panel rely on this property to be updated and many tools, like GTK, want
to use the corresponding client messages to make a window sticky, move it
around etc.
This patch implements full support according to the EWMH spec. This means:
* We set the property on all windows when managing it.
* We keep the property updated on all windows at all times.
* We read and respect the property upon managing a window if it was set before
mapping the window.
* We react to client messages for it.
* We remove the property on withdrawn windows.
Note that the special value 0xFFFFFFFF, according to the spec, means that the
window shall be shown on all workspaces. We do this by making it sticky and
float it. This shows it on all workspaces at least on the output it is on.
Furthermore, the spec gives us the freedom to ignore _NET_WM_DESKTOP when
managing a window if we have good reason to. In our case, we give window
swallowing a higher priority since the user would likely expect that and we
want to keep placeholder windows only around for as long as we have to.
However, we do prioritize this property over, for example, startup
notifications.

Commit 287a0b4 introduced a segfault when validating the i3 config
as the root_screen will not be set in this case, causing a null
pointer dereference.
fixes#2144
We now execute the validations when "kill" is executed even if match
criteria are used. This prevents users from killing workspace containers,
which instead kills all clients (as before when not using criteria).
fixes#1761
Previously, if a match specification contained the con_id or con_mark criterion,
all other criteria were ignored. However, a user may want to specify one of
those two unique identifiers and still specify others as well, for example to
match the currently focused window, but only if it has a certain WM_CLASS:
[con_id=__focused__ class=special] kill
We now check all specified criteria.
fixes#2111
This commit fixes#1969 by adding support for matching a window's type
against _NET_WM_WINDOW_TYPE_NOTIFICATION. The userguide and tests were
updated to reflect this change.
Previously, using a command like
[con_id=foo] kill
would kill the currently focused window because while an error for
not being able to parse the con_id was logged, no further action
was taken, which caused the criterion to be ignored. In this case,
the fallback behavior of using the focused window took over.
For con_id, id and window_type we now reject incorrect values with
an error and abort the command.
fixes#2091
