arguggi / frinfo

Print system information to stdout

Frinfo - Print system info to stdout

Build

Builing with stack is recommended:

$ git clone https://github.com/Arguggi/Frinfo.git
$ cd Frinfo
$ stack build

How-to

The output of frinfo is meant to be piped to dzen:

$ frinfo | dzen2

To see which features are available:

$ frinfo --help

Target OS

Frinfo only works on linux since it reads system info from /proc/ files.

Haskell

Frinfo is mostly a learning excercise. It builds up a data structure using the Free monad which is then interpreted and printed.

Since some statistics need to average the current state with a previous state the StateT monad transformer is used to eliminate some boilerplate.

Don't expect particularly idiomatic Haskell code, this is also still a WIP.
