---==* Rotates backdrops for X11 displays using qiv *==---
--------------------------------------------------------------------------------
-- Introduction --
This works as follow. A configuration file must be created (see example
"sample_wallpaper_list" file) containing one image per line with the
full path. Once the backdropper_consol is started (and pointed to said
file), it will read all the images and pick a random one to display with
qiv. You can get qiv from http://www.klografx.net/qiv/ or change the
source to use whatever viewing program you prefer. It will display all
the images in the configuration file before re-reading it.
A time (delay) between changes can be set. Upcoming is a feature to
only display images while you are at work -- based on time of day and
idleness of the user running backdropper_consol.
A typical usage would be of the form:
backdropper_consol --config'='/home/yann/.rotate_wallpaper_list --delay'='900

-- Quick install guide --
1 - Download Imagemagick. You need "display".
1.5 - Edit src/Rotating_backdrop_logic.hs to add the values you want to
getPossition = "-1280-0"
getResize = "1680>x1050<"
These are for my dual display, yours may vary. Yes, those should be parameters
and will be in the next version. Patches welcome ;>
2 - Create a file (~/.backdropper.list) which contains an image (with full
path) per line. See sample_wallpaper_list for an example of how it should
look like.
3 - Run "runhaskell Setup.hs configure --user".
4 - Run "runhaskell Setup.hs build".
5 - Run "runhaskell Setup.hs haddock".
6 - Run "./dist/build/backdropper_consol/backdropper_consol -h".
7 - Run "sudo runhaskell Setup.hs install".
8 - Run "backdropper_consol --config=$HOME/.backdropper.list --delay=900".
runhaskell Setup.hs configure --user --prefix=$HOME
runhaskell Setup.hs build
runhaskell Setup.hs haddock
runhaskell Setup.hs install
runhaskell Setup.hs configure --user --prefix=$HOME && runhaskell Setup.hs build && runhaskell Setup.hs install

-- Future versions --
* Only rotate during work hours.
* Making sure that all images are shown within a day.
* Make a nice GUI.
