I know formatting commits suck... And I try to avoid them. But this commit was absolutely necessary... The coding style in this program was not ok and not the same over the whole program. The commit is hard to read, but this is what I changed: - Tabs for indentation instead of spaces - Same style over the whole program (suckless style)

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)
|
|
- custom shell commands
|
|
- 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 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).

## 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.
