-# distribution-specific mechanism to find the preferred terminal emulator. On
-# Debian, there is the x-terminal-emulator symlink for example.
-# Please don't touch the first line, though:
- which $TERMINAL >/dev/null && exec $TERMINAL "$@"
+ [ -n "$TERMINAL" ] && which $TERMINAL >/dev/null && exec $TERMINAL "$@"
+# Debian-specific: use x-terminal-emulator
+which x-terminal-emulator >/dev/null && exec x-terminal-emulator "$@"
i3 stores all information about the X11 outputs, workspaces and layout of the
windows on them in a tree. The root node is the X11 root window, followed by
the X11 outputs, then dock areas and a content container, then workspaces and
-finally the windows themselve. In previous versions of i3 we had multiple lists
+finally the windows themselves. In previous versions of i3 we had multiple lists
(of outputs, workspaces) and a table for each workspace. That approach turned
out to be complicated to use (snapping), understand and implement.
*Example*:
-------------------------------------------------
-status_command i3status --config ~/.i3status.conf
+bar {
+ status_command i3status --config ~/.i3status.conf
+}
-------------------------------------------------
=== Display mode
*Example*:
----------------
-mode hide
+bar {
+ mode hide
+}
----------------
=== Position
*Example*:
---------------------
-position top
+bar {
+ position top
+}
---------------------
=== Output(s)
handle all outputs. Restricting the outputs is useful for using different
options for different outputs by using multiple 'bar' blocks.
+To make a particular i3bar instance handle multiple outputs, specify the output
+directive multiple times.
+
*Syntax*:
---------------
output <output>
-------------------------------
# big monitor: everything
bar {
- output HDMI2
- status_command i3status
+ # The display is connected either via HDMI or via DisplayPort
+ output HDMI2
+ output DP2
+ status_command i3status
}
# laptop monitor: bright colors and i3status with less modules.
bar {
- output LVDS1
- status_command i3status --config ~/.i3status-small.conf
- colors {
- background #000000
- statusline #ffffff
- }
+ output LVDS1
+ status_command i3status --config ~/.i3status-small.conf
+ colors {
+ background #000000
+ statusline #ffffff
+ }
}
-------------------------------
*Example*:
-------------------------
# disable system tray
-tray_output none
+bar {
+ tray_output none
+}
# show tray icons on the big monitor
-tray_output HDMI2
+bar {
+ tray_output HDMI2
+}
-------------------------
=== Font
*Example*:
--------------------------------------------------------------
-font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
+bar {
+ font -misc-fixed-medium-r-normal--13-120-75-75-C-70-iso10646-1
+}
--------------------------------------------------------------
=== Workspace buttons
*Example*:
--------------------
-workspace_buttons no
+bar {
+ workspace_buttons no
+}
--------------------
=== Colors
*Example*:
--------------------------------------
-colors {
- background #000000
- statusline #ffffff
-
- focused_workspace #ffffff #285577
- active_workspace #ffffff #333333
- inactive_workspace #888888 #222222
- urgent_workspace #ffffff #900000
+bar {
+ colors {
+ background #000000
+ statusline #ffffff
+
+ focused_workspace #ffffff #285577
+ active_workspace #ffffff #333333
+ inactive_workspace #888888 #222222
+ urgent_workspace #ffffff #900000
+ }
}
--------------------------------------
