Readme

      ---==* 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.
