If an output is disabled during a restart, for example because a binding
such as
bindsym $mod+Shift+r exec "xrandr --auto", restart
is used, it can happen that we first write the layout to disk and only
then receive the RandR change events. This leads to a situation where
the restored tree will contain these outputs, but the restarted i3
process will not receive the RandR events, thus the internal output in i3
is marked disabled.
This patch finds these cases after a restart and force-disables the
affected outputs.
fixes#2326
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.
It should be clear for callers of this function that this is an internal
function that skips certain validations which might be important. Therefore
we make it clear that this is an internal function by renaming it.

This fixes a bug I introduced in #1921. When restarting i3 in place a
stray workspace was created on the root_output during restart. On first
start, this workspace would have been moved to the first real and empty
output.
However, this does not produce the desired result during restarts when
workspaces are alread present on all real outputs. The stray workspace would
still be added to the first real output which already contains some
workspaces. Thus, adding a new empty workspace to it.
Fix this by delaying creation of the root output's workspace until it is
known whether the output is active or not.
Fixes#1940
This patch introduces a root output covering the root window. It is used
in two cases:
1. RandR is not available. In this case, the previous behaviour of
creating a single output covering the root window is preserved.
2. RandR is available, but there is no active output. In this case,
the root output is enabled and will be the only active output.
If any RandR output becomes available, the root output will be
disabled again. Existing mechanisms for migrating workspaces will
just work without modification.
I've carefully slipped in a global variable `Output root_output` representing
that output.

This reverts commit e71c304444.
It turns out that several users have workflows in which they turn off
their monitors without using e.g. `xrandr --output DP-1 --off`. The
result is that the monitors are disconnected, but not disabled.
With commit e71c304444, i3 started to see
these two states as one and the same state, but that causes more harm
than it does good. For example, for some users with only one monitor, i3
would just exit when these users turned off their monitor.

Check if the `connection` of the randr output is
XCB_RANDR_CONNECTION_DISONNECTED and disable the output if it is.
This fixes an issue where the output would not be disabled if the output was
physically unplugged from the machine.
Outputs may disappear momentarily and come back later.
To prevent i3 from exit when no output is available momentarily, add a timeout delay_exit_on_zero_displays.
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.
A good visualization of the new algorithm is this:
+--------+
| |
+--------+=| S1 |========================
| | | |
| S0 | +--------+
| | +--------+
+--------+=========| |================
| S2 | +--------+
| | | |
+--------+ | S3 |
| |
+--------+
When focus is on S0, 'focus output right' will first match S1 (the
closest output which overlaps in the highlighted area), then S2, but not
S3 (since S3 does not overlap into the highlighted area).
fixes#669fixes#771
To automagically do the right thing when rotating monitors with regards
to splith/splitv layout (depending on width/height of the monitor), we
change the orientation of existing workspaces and the first child.
If that first child happens to be a stacked/tabbed con, we cannot change
the layout unconditionally (previously, the orientation was not in the
layout, so we never noticed this problem).
fixes#768
With this commit, the "default" layout is replaced by the splith and
splitv layouts. splith is equivalent to default with orientation
horizontal and splitv is equivalent to default with orientation
vertical.
The "split h" and "split v" commands continue to work as before, they
split the current container and you will end up in a split container
with layout splith (after "split h") or splitv (after "split v").
To change a splith container into a splitv container, use either "layout
splitv" or "layout toggle split". The latter command is used in the
default config as mod+l (previously "layout default"). In case you have
"layout default" in your config file, it is recommended to just replace
it by "layout toggle split", which will work as "layout default" did
before when pressing it once, but toggle between horizontal/vertical
when pressing it repeatedly.
The rationale behind this commit is that it’s cleaner to have all
parameters that influence how windows are rendered in the layout itself
rather than having a special parameter in combination with only one
layout. This enables us to change existing split containers in all cases
without breaking existing features (see ticket #464). Also, users should
feel more confident about whether they are actually splitting or just
changing an existing split container now.
As a nice side-effect, this commit brings back the "layout toggle"
feature we once had in i3 version 3 (see the userguide).
AFAIK, it is safe to use in-place restart to upgrade into versions
after this commit (switching to an older version will break your layout,
though).

The C compiler will handle (void) as "no arguments" and () as "variadic
function" (equivalent to (...)) which might lead to subtle errors, such
as the one which was fixed with commit 0ea64ae4.
If you had workspace 1, 2, 3, 4 on LVDS1 and you enabled HDMI2 (where workspace
1 to workspace 5 are assigned to HDMI2), i3 would look for a new workspace for
LVDS1 (since all workspaces were moved), create workspace 5, move that over due
to assignment and then create workspace 6. Effectively, you would end up with
an empty workspace 5.
