Including config.h is necessary to get e.g. the _GNU_SOURCE define and
any other definitions that autoconf declares. Hence, config.h needs to
be included as the first header in each file.
This is done either via:
1. Including "common.h" (i3bar)
2. Including "libi3.h"
3. Including "all.h" (i3)
4. Including <config.h> directly
Also remove now-unused I3__FILE__, add copyright/license statement
where missing and switch include/all.h to #pragma once.
This code has been neutralized for many years now and served no purpose
other than cluttering up the code. We obviously don't need it and it's
out of date anyway.
If there's ever any reason to restore (parts of) it, we have git for
that. But we don't need to keep commented out code around.
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
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.
relates to #1761
Since splitting a docking container was allowed and successful, the check
to prevent floating it fails to work. This causes a crash because the
workspace of the container cannot be determined as the dockarea is higher
up in the tree than the workspace it belongs to.
This patch extends to sanity check to nested dock containers when trying to
float a container and also disallows manually splitting a docked container
or changing its layout.
fixes#2034
This is necessary during a restart of i3 when restoring floating windows. In this situation, we restore the layout before setting up the RandR outputs which would set the window's size to 0, making it invisible.
Thanks to hwangcc23 and spudowiar for reporting.

This commit also reworks the way focusing sticky windows is prevented by not focusing them temporarily at all, but preventing the focus in the first place.
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.
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.
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.
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.
This change ensures a scratchpad window is still centered on the screen
if it has first been shown on another screen of a different
resolution. Moving or resizing the scratchpad manually disables this
behavior.
• our function names use underscores
• rewrote the function’s comment
• function comments must be in the source _and_ in the header
• no blank lines after function signatures
Previously, while the loop would not be executed anymore, the callback
(for actually repositioning the window after a MotionNotify) would still
get called once. This commit avoids that, thus fixing the crash.
fixes#819
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).
Fixes#464
When calculating coordinates we should multiply at first otherwise
we lose precision when i3 is compiled without sse2 support.
The following code prints "Res1: 348 Res2: 349" when compiled with
-O0 -mno-sse2 and "Res1: 349 Res2: 349" with -O0 -msee2.
Note that -msse2 is default flag on 64bit OSes.
int main() {
double a = 349.0 / 768;
double b = 349.0 * 768;
int res1 = a * 768;
int res2 = b / 768;
printf("Res1: %d Res2: %d\n", res1, res2);
return 0;
}
Thanks guys for helping me to hunt down this one.

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.
Fixes: #668
Calling tree_close with dont_kill_parent=true will avoid it from closing the
workspace if it’s empty (and it’s temporarily empty, because 'floating disable'
detaches, then re-attaches the window).
The problem was that the workspace was considered empty for a brief period of
time when entering floating mode. This happened when you assigned Gimp to a
workspace which is not in use yet.
Fixes#452
This might also fix problems with Firefox where Firefox only displays a white
window (my guess is that it mapped a floating window outside of the actually
visible area for some reason).
Use 'kill window' to kill a specific window (for example only one specific
popup), use 'kill client' to kill the whole application (or X11 connection to
be specific).
