Controls the window titles alignment in title bars. Possible values are:
- left
- center
- right
Co-authored-by: Orestis Floros <orestisf1993@gmail.com>
- Made title_align a config directive instead of a command. Helps with
some tree_render() issues we had.
- Made title_max_width the same for all 3 cases.
- Modified title offset calculations and added explanations for each
case.
- Append title_padding to mark_width if a mark exists.
Fixes#1750
Benefits are that we don't open a fake container and don't call many
complicated functions that can lead to redraws (x_push_changes calls) as
discussed in #2954.
Fixes#2810:
Windows exchange floating mode & window rects.
Swap will still not work with CT_FLOATING_CONs but this doesn't make
much sense.
Fixes#3280:
The behaviour is not very user friendly but swap behaves exactly as it
should. The rest is a tree_flatten issue. Attached pictures in #2954.
Modified section on the layout file's non-compliance with the JSON
standard. The section previously stated that having multiple top-level
JSON texts is non-compliant. This isn't the case. It's just that most
JSON parsers will treat that as if it is non-compliant.
Introduces resize_neighboring_cons in resize.c which is also used by
resize_graphical_handler.

Authored original code and tests in #3240. I rewrote most of the
resizing code and fixed the failing tests.
This change only affects clients that are subscribed to events, which
should be the main cause of our problems.
In the common case (no buffered data) the behaviour doesn't change at
all: the message is sent directly, no ev_io / ev_timeout callback is
enabled. Once a write to a client's socket is not completed fully
(returns with EAGAIN error), we put the message in the tail of a queue
and init an ev_io callback and a corresponding timer. If the timer is
triggered first, the socket is closed and the client connection is
removed. If the socket becomes writeable before the timeout we either
reset the timer if we couldn't push all the buffered data or completely
remove it if everything was pushed.
We could also replace ipc_send_message() for all client connections in
i3, not just those subscribed to events.
Furthermore, we could limit the amount of messages stored and increase
the timeout (or use multiple timeouts): eg it's ok if a client is not
reading for 10 seconds and we are only holding 5KB of messages for them
but it is not ok if they are inactive for 5 seconds and we have 30MB of
messages held.

The current text is confusing. '--no-auto-back-and-forth' doesn't
disable the 'workspace back_and_forth' command, the flag is not even
valid for that command.
- 'border toggle' now accepts an optional pixel argument which will be
ignored when switching to BS_NONE.
- 'border pixel' now defaults to 1 pixel instead of 2.
- Calling 'border normal' or 'border pixel' will use the configured
default_border_width if one exists. Also applies to floating windows.
Sending the sync command via IPC ensures pending IPC messages are handled by i3
before the sync response is read. This is rarely useful for direct IPC
connections to i3, but becomes useful when synchronizing with i3bar, which might
have pending IPC messages in response to button clicks.
For command:
move window to [absolute] position X px Y px
if the optional keyword 'absolute' is provided the end result is the
same even though it is implemented differently. Only difference is that
with absolute the floating window can move completely outside of any
output.
This commit removes the 'method' argument and only keeps the sane
implementation.
The front page and docs landing page emphasize documentation, but the user guide looks like it hasn't been updated since 2013. It seems from the history of the file that this number is misleading. Let me know if I'm missing anything.
Add support for relative coordinates in i3bar click events
Rename {x,y}_rel to relative_{x,y}
Update i3bar-protocol doc to mention the added fields in click events
i3bar's handle_button is modified to also handle XCB_BUTTON_RELEASE
events. During these button release events, only custom commands are
checked to avoid sending multiple workspace ipc messages.
The way this patch is implemented will allow to assign a custom command
for both the press and release of the same button:
bar {
...
bindsym buttonX exec command1
bindsym --release buttonX exec command2
}
Fixes#3068.
The userguide still mentions an old 'goto' command which no longer
exists and will be ignored silently (when used in the i3 config) or
causes an error to be reported (when invoked from the command line).
This change updates the userguide to correct this problem. In addition
to that it also updates the i3-input command shown to no longer use the
deprecated -p flag but -F instead.
Allow enabling forced focus wrapping by specifying "focus_wrapping
force" in i3's configuration. This syntax supersedes the previous
"force_focus_wrapping yes" one, which remains available for backwards
compatibility.
All other message types are verbs, only our first-ever message COMMAND wasn’t.
While we’re here, also change the message type dictionary into a table with
clickable links to the corresponding reply type.
Authors of downstream IPC libraries are encouraged to keep the old name around
so as to not break existing code, but mark it as deprecated.
Makes "assign [<criteria>] workspace number <number>" work in the same
manner as "move to workspace number <number>" instead of assigning the
window to a workspace named "number <number>".
config.spec is modified to expect a 'number' string and an extra
argument is used in cfg_assign.
For workspaces that don't exist yet, workspace_get is used as a
fallback. This also allows the user to assign to "<number> <workspace>"
eg "2: work" and the full name will be used if workspace number 2
doesn't exist yet.
Fixes#2590.
- Promote the "How to build?" sub-section to a top-level
section ("Building i3")
- Convert the "Introduction" sub-section as the intro to the remaining
contents of the "Using git / sending patches" section
- Keep "Which branch to use?" as a level-3 sub-section, thus making it
a sub-section of what used to be the "Introduction" sub-section.
This introduces the flag --exclude-titlebar for mouse bindings which
allows bindings like
bindsym --whole-window --border --exclude-titlebar button3 focus
fixes#2347
With this PR the 'layout toggle' command can be passed any
combination of valid layout keywords as arguments. They will
be activated one after another each time you issue the command,
advancing from left to right always selecting the layout after
the currently active layout or the leftmost layout if the active
layout is not in the argument list.
This PR also incorporates the feature request from #2476.
The possible values "rename", "reload" and "restored" of the property
'change' from the workspace event were missing. Because no events of
those types contain an old workspace, this was trivial.
This event is triggered when the connection to the ipc is about to
shutdown because of a user action such as with a `restart` or `exit`
command. The `change` field indicates why the ipc is shutting down. It
can be either "restart" or "exit".
fixes#2318
This commit probably comes as a surprise to some, given that one of i3’s
explicitly stated goals used to be “Do not use programs such as
autoconf/automake for configuration and creating unreadable/broken makefiles”.
I phrased this goal over 7 years ago, based largely on a grudge that I
inherited, which — as I’ve realized in the meantime — was largely held against
FOSS in general, and not actually nuanced criticism of autotools.
In the meantime, I have come to realize that the knee-jerk reaction of “I could
do this better!” (i.e. writing our own build system in this particular case) is
usually misguided, and nowadays I strongly suggest trying hard to fix the
existing system for the benefit of all existing and future users.
Further, I recently got to experience the other side of the coin, as I packaged
a new version of FreeRADIUS for Debian, which at the time of writing used
autoconf in combination with boilermake, a custom make-based build system that
only FreeRADIUS uses. Understanding the build system enough to fix issues and
enable parallel compilation took me an entire day. That time is time which
potentially every downstream maintainer needs to invest, and the resulting
knowledge cannot be applied to any other project.
Hence, I believe it’s a good idea switch i3 to autotools. Yes, it might be that
particular features were easier to implement/understand in our custom
Makefiles, and there might be individuals who have an easier time reading
through our custom Makefiles than learning autotools. All of these
considerations are outweighed by the benefits we get from using the same build
system as literally thousands of other FOSS software packages.
Aside from these somewhat philosophical considerations, there’s also practical
improvements which this change brings us. See the “changes” section below.
┌──────────────────────────────────────────────────────────────────────────────┐
│ new workflow │
└──────────────────────────────────────────────────────────────────────────────┘
You can now build i3 like you build any other software package which uses
autotools. Here’s a memory refresher:
autoreconf -fi
mkdir -p build && cd build
../configure
make -j8
(The autoreconf -fi step is unnecessary if you are building from a release
tarball, but shouldn’t hurt either.)
┌──────────────────────────────────────────────────────────────────────────────┐
│ recommended reading │
└──────────────────────────────────────────────────────────────────────────────┘
I very much recommend reading “A Practitioner's Guide to GNU Autoconf,
Automake, and Libtool” by John Calcote (https://www.nostarch.com/autotools.htm).
That book is from 2010 and, AFAICT, is the most up to date comprehensive
description of autotools. Do not read older documentation. In particular, if a
document you’re reading mentions configure.in (deprecated filename) or
recursive make (now considered harmful), it’s likely outdated.
┌──────────────────────────────────────────────────────────────────────────────┐

└──────────────────────────────────────────────────────────────────────────────┘
This commit implements the following new functionality/changes in behavior:
• We use the AX_ENABLE_BUILDDIR macro to enforce builds happening in a separate
directory. This is a prerequisite for the AX_EXTEND_SRCDIR macro and building
in a separate directory is common practice anyway. In case this causes any
trouble when packaging i3 for your distribution, please let me know.
• “make check” runs the i3 testsuite.
You can still use ./testcases/complete-run.pl to get the interactive progress
output.
• “make distcheck” (runs testsuite on “make dist” result, tiny bit quicker
feedback cycle than waiting for the travis build to catch the issue).
• “make uninstall” (occasionally requested by users who compile from source)
• “make” will build manpages/docs by default if the tools are installed.
Conversely, manpages/docs are not tried to be built for users who don’t want
to install all these dependencies to get started hacking on i3.
• non-release builds will enable address sanitizer by default. Use the
--disable-sanitizers configure option to turn off all sanitizers, and see
--help for available sanitizers.
• Support for pre-compiled headers (PCH) has been dropped for now in the
interest of simplicitly. Maybe we can re-add it later.
• coverage reports are now generated using “make check-code-coverage”, which
requires specifying --enable-code-coverage when calling configure.
┌──────────────────────────────────────────────────────────────────────────────┐
│ build system feature parity/testing │
└──────────────────────────────────────────────────────────────────────────────┘
In addition to what’s described above, I tested the following features:
• “make install” installs the same files (plus documentation and manpages)
cd i3-old && make install PREFIX=/tmp/inst/old
cd i3-new && ./configure --prefix=/tmp/inst/new
cd /tmp/inst
(cd old && for f in $(find); do [ -e "../new/$f" ] || echo "$f missing"; done)
• make dist generates a tarball which includes the same files
cd i3-old && make dist
cd i3-new/x86_64-pc-linux-gnu && make dist
colordiff -u <(tar tf i3-old/i3-4.12.tar.bz2 | sort) \
<(tar tf i3-new/x86_64-pc-linux-gnu/i3-4.12.tar.gz | sort)
There are some expected differences:
• Some files have been renamed (e.g. the new etc/ and share/ subdirectories)
• Some files will now be generated at build-time, so only their corresponding
.in file is shipped (e.g. testcases/complete-run.pl)
• The generated parser files are shipped in the dist tarball (they only
depend on the parser-specs/* files, not on the target system)
• autotools infrastructure is shipped (e.g. “configure”, “missing”, etc.)
• DLOG and ELOG statements still produce the same file name in logfiles
• Listing source code in gdb still works.
• gdb backtraces contain the i3-<version> path component
• release.sh still works
• version embedding
1. git checkout shows “4.12-136-gf720023 (2016-10-10, branch "autotools")”
2. tarball of a git version shows “4.12-non-git”
3. release tarball shows 4.13
• debug mode is enabled by default for non-release builds
• enabling verbose builds via V=1
┌──────────────────────────────────────────────────────────────────────────────┐
│ speed │
└──────────────────────────────────────────────────────────────────────────────┘
There is no noticeable difference in compilation speed itself (of binaries,
documentation and manpages):
i3-old $ time make all docs mans -j8
make all docs mans -j8 28.92s user 2.15s system 640% cpu 4.852 total
i3-new $ time make -j8
make -j8 27.08s user 1.92s system 620% cpu 4.669 total
In terms of one-time costs:
configuring the build system (../configure) takes about 2.7s on my machine,
generating the build system (autoreconf -fi) takes about 3.1s on my machine.
┌──────────────────────────────────────────────────────────────────────────────┐
│ m4 macros │
└──────────────────────────────────────────────────────────────────────────────┘
All files in m4/ have been copied from the autoconf-archive package in version
b6aeb1988f4b6c78bf39d97b6c4f6e1d594d59b9 and should be updated whenever they
change.
This commit has been tested with autoconf 2.69 and automake 1.15.
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
