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.
i3status has the following dependencies:
- libconfuse-dev
- libyajl-dev
- libasound2-dev
- libnl-genl-3-dev
- libcap2-bin (for getting network status without root permissions)
- asciidoc (only for the documentation)
- libpulse-dev (for getting the current volume using PulseAudio)
On debian-based systems, the following line will install all requirements:
apt-get install libconfuse-dev libyajl-dev libasound2-dev libiw-dev asciidoc libcap2-bin libpulse-dev
i3status is developed at https://github.com/i3/i3status
Compiling is done with the usual make-line
make && sudo make install
