This helps for windows which are immediately destroyed instead of
unmapped, like when starting i3status | ./foobar | dzen2 -dock
and foobar does not exist (i3status and dzen2 will get a SIGPIPE).
Before this commit, i3 used key bindings in SYNC mode for bindings
like Mode_switch + <a> and replayed the key if the current state
did not include Mode_switch. This had some problems:
1) The WM needed to acknowledge much more key presses than you
actually had bindings for, thus making the system a bit laggy
sometimes.
2) Users of layouts who constantly type in the third level (like
russian layouts) did not get their cyrillic symbols correctly
(they were not replayed right), neither did the keybindings
work in both modes.
So, the current implementation uses the following approach: XKB
provides an event which contains the current state (including
the current level). i3 signs up for this event and upon receival,
it re-maps the bindings using Mode_switch (enables them when the
level goes to the third level and disables them as soon as the
level goes back to normal). This fixes both problems.
Add --force-xinerama when starting i3 to use Xinerama instead of RandR.
This should *ONLY* be done if you have no other choice (nvidia’s
binary driver uses twinview and does not expose the monitor information
through RandR).
Thanks to Merovius for doing a proof of concept on this one and
being a driving force behind the idea.
Using RandR instead of Xinerama means that we are now able to use
the full potential of the modern way of configuring screens. That
means, i3 now has an idea of the outputs your graphic driver
provides, which allowed us to get rid of the ugly way of detecting
changes in the screen configuration which we used before. Now, your
workspaces should not be confused when changing output modes anymore.
Also, instead of having ugly heuristics to assign your workspaces
to (the screen at position X or the second screen in the list of
screens) you will be able to just specify an output name.
As this change basically touches everything, you should be prepared
for bugs. Please test and report them!
Please note that rdesktop’s -g workarea option will not work on
64-bit systems at the moment because of a bug in rdesktop (see the
rdesktop-devel mailing list).
This fixes many problems we were having with a dynamically growing
array because of the realloc (pointers inside the area which was
allocated were no longer valid as soon as the realloc moved the
memory to another address).
Again, this is a rather big change, so expect problems and enable
core-dumps.
The following new directives have been implemented for the configuration
file:
new_container <default|stacking|tabbed>
new_container stack-limit <cols|rows> <value>
Note that they require using the new lexer/parser, which you can
do by passing -l to i3 when starting.
For example, you can create a mode which will let you resize windows
with some easy to use keys. So, instead of binding a combination
of your homerow and modifiers to resize, like this:
bind Mod4+44 resize right +10
bind Mod4+45 resize right -10
...
You can instead define a new mode:
mode "resize" {
bind 44 resize right +10
bind 45 resize right -10
...
bind 36 mode default
}
bindsym Mod4+r mode resize
So, if you press Mod4+r now, your keybindings will be set to the ones
defined in your resize mode above. You can then use your homerow
(without any other modifier) to resize the current column/row and
press enter to go back to the default mode when you are done.
Note that using this option requires you to enable the new lexer/parser
by passing the -l flag to i3 when starting.
Using this command, you can limit the amount of columns or rows for
a stacking container. This allows for better usage of screen estate
when using stacking containers with many clients.
Examples:
i3-msg "stack-limit cols 2"
You will now have a stack window which has two columns of windows.
Thanks to Mikael for bringing it to my mind. This change introduces
two new color classes, client.urgent and bar.urgent. By default,
urgent clients are drawn in red (colors by Atsutane).
Please test this! Plug in screens, unplug them, use your video projector,
change resolutions, etc.
To use the assignments, use the following syntax:
workspace <number> [screen <screen>] [name]
Where screen can be one of:
<number> (It is not provided that these numbers stay constant, so use with care)
<x>x<y> (Coordinates where the screen starts, so 1280 will be fine to match the
screen right of the main screen if your main screen is 1280 pixels
width. However, 1281 will not match)
<x>
x<y>
Some examples follow:
workspace 1 screen 0
workspace 1 screen 1
workspace 1 screen 1280x0
workspace 2 screen 1280
workspace 3 screen x0
workspace 3 screen 1 www
workspace 4 screen 0 mail
Use "bindsym" instead of "bind". You have to use the names of keys
as in xmodmap. To get a list of currently bounud symbols, use
xmodmap -pke
Technical quirk: Xlib generated MappingNotify events upon
XkbMapNotify events (from XKB, as the name says). XCB does not yet
have support for XKB, thus we need to select and handle the event
by ourself. Hopefully, this will change in the future.
Also update documentation (manpage, userguide).
To make the code easier to read/write when checking if a client is
floating, introduce client_is_floating().
Fixes a race condition with GIMP (where it configured its window,
sent the map request and waited for the window to get mapped, but
i3 didn’t get the event until another one was sent (key binding for
example)).
The new solution is much better as it properly hands off all
the work to xcb_poll_for_event.
Inspired by awesome, which uses the same mechanism. Thanks.
Instead of building arrays of colorpixels we can simply use a pointer
to a struct Colortriple. Furthermore, by getting the colorpixels when
loading the configuration, we save a lot of function calls in the
main code.
