As the workspaces are now created dynamically, we cannot rely on
the workspaces to be there when we need them without creating them.
On the other hand, this eliminates the case that there are no workspaces
to assign to a new screen, because now we can just create one.
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.
Warning: This is not yet thoroughly tested, so be prepared to
encounter some segfaults. Please enable logging and coredumps,
so we can fix bugs quickly.
xterm by default sets a border_width of 2. This was not taken into
account when determining the size of the window by i3. Still, you
probably want to set this to 0 in your .Xresources as the pixels
are just lost.
We now use the virtual screen’s size/position instead of the X root
window for the grabwin (grabwin = the area in which the pointer may
move when resizing).
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.
Commands are 'mark' and 'goto'. Both can be used either directly,
like 'mark a' and 'goto a', or interactively (just 'mark'). For
interactive mode, i3-input must be installed and in your PATH.
This warning only showed up with CFLAGS=-O2.
The variables in question could never be uninitialized because
they were definitely set, have a look at the code. But anyways,
less warnings is always a good thing ;-).
This is necessary because otherwise the window into which the
pointer is warped still is at its old position, so that the pointer
will effectively be warped onto the wrong screen in case of moving
a window to another screen.
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).
Before this fix, you could go upwards and select the screen which
was at the rightmost because it also was the one topmost (if all
screen’s top position is equal).
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.
Use bn (normal), bp (1-px), bb (borderless) as commands to change the
border style of the currently focused window. Feel free to use i3-msg
to do this.
Thus, no more flickering because the window was first mapped and then
moved. Especially users of multiple monitors should be happy now ;-).
Rather radical change, though, so be prepared for problems.
