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 500 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)
- date and time
- disk numbers (free storage, percentage, total storage and used storage)
- available entropy
- hostname
- ip addresses
- ram numbers (free ram, percentage, total ram and used ram)
- temperature
- volume percentage (alsa)
- wifi percentage
Multiple entries per function are supported and everything can be reordered and customized via the C header file config.h (similar to DWM).
## 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.
