slstatus 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). **slstatus** is a suckless and lightweight status monitor for window managers that 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 to be 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.

### Installation ### 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`! Before you continue, please be sure that a C compiler (preferrably gcc), GNU make and `alsa-lib` (for volume percentage) are installed. Then copy config.def.h to config.h and customize it to fit your needs. Recompile and install it after modifications:
$ make clean all
# make install
