== NAME
== CONFIGURATION
-Since version 2, the configuration file for i3status will be parsed using
-libconfuse. This makes configuration easier in the programmer’s point of
-view and more flexible for the user at the same time.
-
The basic idea of i3status is that you can specify which "modules" should
be used (the order directive). You can then configure each module with its
own section. For every module, you can specify the output format. See below
order += "battery 0"
order += "cpu_temperature 0"
order += "load"
-order += "time"
+order += "tztime local"
+order += "tztime berlin"
wireless wlan0 {
format_up = "W: (%quality at %essid, %bitrate) %ip"
battery 0 {
format = "%status %percentage %remaining %emptytime"
path = "/sys/class/power_supply/BAT%d/uevent"
+ low_threshold = 10
}
run_watch DHCP {
pidfile = "/var/run/vpnc/pid"
}
-time {
- format = "%Y-%m-%d %H:%M:%S"
+tztime local {
+ format = "%Y-%m-%d %H:%M:%S"
+}
+
+tztime berlin {
+ format = "%Y-%m-%d %H:%M:%S %Z"
+ timezone = "Europe/Berlin"
}
load {
Using +output_format+ you can chose which format strings i3status should
use in its output. Currently available are:
+i3bar::
+i3bar comes with i3 and provides a workspace bar which does the right thing in
+multi-monitor situations. It also comes with tray support and can display the
+i3status output. This output type uses JSON to pass as much meta-information to
+i3bar as possible (like colors, which blocks can be shortened in which way,
+etc.).
dzen2::
Dzen is a general purpose messaging, notification and menuing program for X11.
It was designed to be scriptable in any language and integrate well with window
Does not use any color codes. Separates values by the pipe symbol. This should
be used with i3bar and can be used for custom scripts.
+It's also possible to use the color_good, color_degraded, color_bad directives
+to define specific colors per module. If one of these directives is defined
+in a module section its value will override the value defined in the general
+section just for this module.
+
=== IPv6
This module gets the IPv6 address used for outgoing connections (that is, the
Gets used, free, available and total amount of bytes on the given mounted filesystem.
+These values can also be expressed in percentages with the percentage_used,
+percentage_free, percentage_avail and percentage_used_of_avail formats.
+
*Example order*: +disk /mnt/usbstick+
*Example format*: +%free (%avail)/ %total+
+*Example format*: +%percentage_used used, %percentage_free free, %percentage_avail avail+
+
=== Run-watch
Expands the given path to a pidfile and checks if the process ID found inside
=== Battery
-Gets the status (charging, discharging, running), percentage and remaining
-time of the given battery and when it's estimated to be empty. If you want
-to use the last full capacity instead of the design capacity (when using
-the design capacity, it may happen that your battery is at 23% when fully
-charged because it’s old. In general, I want to see it this way, because
-it tells me how worn off my battery is.), just specify
+Gets the status (charging, discharging, running), percentage, remaining
+time and power consumption (in Watts) of the given battery and when it's
+estimated to be empty. If you want to use the last full capacity instead of the
+design capacity (when using the design capacity, it may happen that your
+battery is at 23% when fully charged because it’s old. In general, I want to
+see it this way, because it tells me how worn off my battery is.), just specify
+last_full_capacity = true+.
+If you want the battery percentage to be shown without decimals, add
++integer_battery_capacity = true+.
+
If your battery is represented in a non-standard path in /sys, be sure to
modify the "path" property accordingly. The first occurence of %d gets replaced
with the battery number, but you can just hard-code a path as well.
+It is possible to define a low_threshold that causes the battery text to be
+colored red. The low_threshold type can be of threshold_type "time" or
+"percentage". So, if you configure low_threshold to 10 and threshold_type to
+"time", and your battery lasts another 9 minutes, it will be colored red.
+
*Example order*: +battery 0+
-*Example format*: +%status %remaining (%emptytime)+
+*Example format*: +%status %remaining (%emptytime %consumption)+
+
+*Example low_threshold*: +30+
+
+*Example threshold_type*: +time+
=== CPU-Temperature
-Gets the temperature of the given thermal zone.
+Gets the temperature of the given thermal zone. It is possible to
+define a max_threshold that will color the temperature red in case the
+specified thermal zone is getting too hot. Defaults to 75 degrees C.
*Example order*: +cpu_temperature 0+
*Example format*: +T: %degrees °C+
+*Example max_threshold*: +42+
+
=== CPU Usage
-Gets the percentual CPU usage from +/proc/stat+.
+Gets the percentual CPU usage from +/proc/stat+ (Linux) or +sysctl(3)+ (FreeBSD/OpenBSD).
*Example order*: +cpu_usage+
=== Time
-Formats the current system time. See +strftime(3)+ for the format.
+Outputs the current time in the local timezone.
+To use a different timezone, you can set the TZ environment variable,
+or use the +tztime+ module.
+See +strftime(3)+ for details on the format string.
*Example order*: +time+
*Example format*: +%Y-%m-%d %H:%M:%S+
+=== TzTime
+
+Outputs the current time in the given timezone.
+If no timezone is given, local time will be used.
+See +strftime(3)+ for details on the format string.
+The system's timezone database is usually installed in +/usr/share/zoneinfo+.
+Files below that path make for valid timezone strings, e.g. for
++/usr/share/zoneinfo/Europe/Berlin+ you can set timezone to +Europe/Berlin+
+in the +tztime+ module.
+
+*Example order*: +tztime berlin+
+
+*Example format*: +%Y-%m-%d %H:%M:%S %Z+
+
+*Example timezone*: +Europe/Berlin+
+
=== DDate
Outputs the current discordian date in user-specified format. See +ddate(1)+ for
Outputs the volume of the specified mixer on the specified device. Works only
on Linux because it uses ALSA.
+A simplified configuration can be used on FreeBSD and OpenBSD due to
+the lack of ALSA, the +device+, +mixer+ and +mixder_idx+ options can be
+ignored on these systems. On these systems the OSS API is used instead to
+query +/dev/mixer+ directly.
*Example order*: +volume master+
could display it. The display number is therefore often incorrect and doesn’t
tell you anything useful either.
-In general, i3status wants to display things which you would often look at
-anyways, like the current date/time, whether you are connected to a WiFi
-network or not, and if you have enough disk space to fit that 4.3 GiB download.

+occasionally anyways, like the current date/time, whether you are connected to
+a WiFi network or not, and if you have enough disk space to fit that 4.3 GiB

However, if you need to look at some kind of information more than once in a
while (like checking repeatedly how full your RAM is), you are probably better
-of with a script doing that, which pops up an alert when your RAM usage reaches
-a certain threshold.
+off with a script doing that, which pops up an alert when your RAM usage reaches
+a certain threshold. After all, the point of computers is not to burden you
+with additional boring tasks like repeatedly checking a number.
== External scripts/programs with i3status
Put that in some script, say +.bin/my_i3status.sh+ and execute that instead of i3status.
+Note that if you want to use the JSON output format (with colors in i3bar), you
+need to use a slightly more complex wrapper script. There are examples in the
+contrib/ folder, see http://code.i3wm.org/i3status/tree/contrib
+
+== SIGNALS
+
+When receiving +SIGUSR1+, i3status’s nanosleep() will be interrupted and thus
+you will force an update. You can use killall -USR1 i3status to force an update
+after changing the system volume, for example.
