**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).
-The following information is included:
+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.
-- wifi percentage
-- battery percentage
-- cpu usage in percent
-- cpu temperature
-- ram usage in percent
-- alsa volume level in percent
-- disk usage
-- date
-- time
+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.
-Multiple entries (battery, wifi signal, ...) are supported and everything can be reordered and customized via a C header file (similar to DWM).
+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).
## Usage
### Installation
-Before you continue, please be sure that a C compiler, `make` and `alsa-lib` are installed. Then compile the program once using `sudo make install`. After that you may change config.h to your needs and recompile it after any change!
+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`!
