slstatus ======== **slstatus** is a suckless and lightweight status monitor for window managers which use WM_NAME as statusbar (e.g. DWM). It is written in pure C without any system() calls and only reads from files most of the time. It is meant as a better alternative to Bash scripts (inefficient) and Conky (bloated for this use). If you write a bash script that shows system information in WM_NAME, it executes a huge amount of external command (top, free etc.) every few seconds. This results in high system resource usage. slstatus solves this problem by only using C libraries and/or reading from files in sysfs / procfs. Looking at the LOC (lines of code) in the [Conky project](https://github.com/brndnmtthws/conky) is very interesting: *28.346 lines C++, 219 lines Python and 110 lines Lua*. slstatus currently has about **600 lines of clean, well commented C code** and even includes additional possibilities as it can be customized and extended very easily. Configuring it by editing config.h (a C header file) is very secure and fast as no config files are parsed at runtime. The following information is included: - battery percentage - cpu usage (in percent) - custom shell commands - date and time - disk numbers (free storage, percentage, total storage and used storage) - available entropy - username/gid/uid of current user - hostname - ip addresses - load average - ram numbers (free ram, percentage, total ram and used ram) - temperature - uptime - volume percentage + mute status (alsa) - wifi signal percentage and essid Multiple entries per function are supported and everything can be reordered and customized via the C header file config.h (similar to DWM). ![screenshot](screenshot.png) ## Usage ### Installation Before you continue, please be sure that a C compiler, GNU make and `alsa-lib` (for volume percentage) are installed. Then copy config.def.h to config.h and edit it to your needs. Recompile and install it after every change via `sudo make install`! ### Starting Put the following code in your ~/.xinitrc (or similar): ``` while true; do slstatus done & ``` The loop is needed that the program runs after suspend to ram. ## Contributing In [TODO.md](TODO.md) there is a list of things that have to be done.
