i3 - improved tiling WM

1. NAME

i3status - Generates a status line for dzen2 or xmobar

2. SYNOPSIS

i3status [-c configfile] [-h] [-v]

3. OPTIONS

-c

Specifies an alternate configuration file path. By default, i3status looks for configuration files in the following order:

~/.i3status.conf
~/.config/i3status/config (or $XDG_CONFIG_HOME/i3status/config if set)
/etc/i3status.conf
/etc/xdg/i3status/config (or $XDG_CONFIG_DIRS/i3status/config if set)

4. DESCRIPTION

i3status is a small program (about 1500 SLOC) for generating a status bar for i3bar, dzen2, xmobar or similar programs. It is designed to be very efficient by issuing a very small number of system calls, as one generally wants to update such a status line every second. This ensures that even under high load, your status bar is updated correctly. Also, it saves a bit of energy by not hogging your CPU as much as spawning the corresponding amount of shell commands would.

5. 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 for a complete reference.

Sample configuration

general {
        output_format = "dzen2"
        colors = true
        interval = 5
}

order  = "ipv6"
order += "disk /"
order += "run_watch DHCP"
order += "run_watch VPN"
order += "wireless wlan0"
order += "ethernet eth0"
order += "battery 0"
order += "cpu_temperature 0"
order += "load"
order += "time"

wireless wlan0 {
        format_up = "W: (%quality at %essid, %bitrate) %ip"
        format_down = "W: down"
}

ethernet eth0 {
        # if you use %speed, i3status requires the cap_net_admin capability
        format_up = "E: %ip (%speed)"
        format_down = "E: down"
}

battery 0 {
        format = "%status %percentage %remaining"
}

run_watch DHCP {
        pidfile = "/var/run/dhclient*.pid"
}

run_watch VPN {
        pidfile = "/var/run/vpnc/pid"
}

time {
        format = "%Y-%m-%d %H:%M:%S"
}

load {
        format = "%5min"
}

cpu_temperature 0 {
        format = "T: %degrees °C"
        path = "/sys/devices/platform/coretemp.0/temp1_input"
}

disk "/" {
        format = "%free"
}

5.1. General

The colors directive will disable all colors if you set it to false. You can also specify the colors that will be used to display "good", "degraded" or "bad" values using the color_good, color_degraded or color_bad directives, respectively. Those directives are only used if color support is not disabled by the colors directive. The input format for color values is the canonical RGB hexadecimal triplet (with no separators between the colors), prefixed by a hash character ("#").

Example configuration:

color_good = "#00FF00"

Likewise, you can use the color_separator directive to specify the color that will be used to paint the separator bar. The separator is always output in color, even when colors are disabled by the colors directive.

The interval directive specifies the time in seconds for which i3status will sleep before printing the next status line.

Using output_format you can chose which format strings i3status should use in its output. Currently available are:

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 managers like dwm, wmii and xmonad though it will work with any windowmanger
xmobar: xmobar is a minimalistic, text based, status bar. It was designed to work with the xmonad Window Manager.
none: 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.

5.2. IPv6

This module gets the IPv6 address used for outgoing connections (that is, the best available public IPv6 address on your computer).

Example format_up: %ip

Example format_down no IPv6

5.3. Disk

Gets used, free, available and total amount of bytes on the given mounted filesystem.

Example order: disk /mnt/usbstick

Example format: %free (%avail)/ %total

5.4. Run-watch

Expands the given path to a pidfile and checks if the process ID found inside is valid (that is, if the process is running). You can use this to check if a specific application, such as a VPN client or your DHCP client is running.

Example order: run_watch DHCP

5.5. Wireless

Gets the link quality and ESSID of the given wireless network interface. You can specify different format strings for the network being connected or not connected.

Example order: wireless wlan0

Example format: W: (%quality at %essid, %bitrate) %ip

5.6. Ethernet

Gets the IP address and (if possible) the link speed of the given ethernet interface. Getting the link speed requires the cap_net_admin capability. Set it using setcap cap_net_admin=ep $(which i3status).

Example order: ethernet eth0

Example format: E: %ip (%speed)

5.7. Battery

Gets the status (charging, discharging, running), percentage and remaining time of the given battery. 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.

Example order: battery 0

Example format: %status %remaining

5.8. CPU-Temperature

Gets the temperature of the given thermal zone.

Example order: cpu_temperature 0

Example format: T: %degrees °C

5.9. CPU Usage

Gets the percentual CPU usage from /proc/stat.

Example order: cpu_usage

Example format: %usage

5.10. Load

Gets the system load (number of processes waiting for CPU time in the last 5, 10 and 15 minutes).

Example order: load

Example format: %5min %10min %15min

5.11. Time

Formats the current system time. See strftime(3) for the format.

Example order: time

Example format: %Y-%m-%d %H:%M:%S

5.12. DDate

Outputs the current discordian date in user-specified format. See ddate(1) for details on the format string. Note: Neither %. nor %X are implemented yet.

Example order: ddate

Example format: %{%a, %b %d%}, %Y%N - %H

5.13. Volume

Outputs the volume of the specified mixer on the specified device. Works only on Linux because it uses ALSA.

Example order: volume master

Example format: ♪: %volume

Example configuration:

volume master {
        format = "♪: %volume"
        device = "default"
        mixer = "Master"
        mixer_idx = 0
}

6. Using i3status with dzen2

After installing dzen2, you can directly use it with i3status. Just ensure that output_format is set to dzen2.

Example for usage of i3status with dzen2:

i3status | dzen2 -fg white -ta r -w 1280 \
-fn "-misc-fixed-medium-r-normal--13-120-75-75-C-70-iso8859-1"

7. Using i3status with xmobar

To get xmobar to start, you might need to copy the default configuration file to ~/.xmobarrc. Also, ensure that the output_format option for i3status is set to xmobar.

Example for usage of i3status with xmobar:

i3status | xmobar -o -t "%StdinReader%" -c "[Run StdinReader]"
