[Remind-Fans] A little script I use to put remind on the desktop

[Martin Hansen]

Hi,

I did not get Your script working. I am getting a "convert: Postscript delegate failed `/tmp/magick-XXB0tWqO': No such file or directory.", so I think it is a bug on my machine. However:

I am also working on a script that puts Remind on a Xfce4
desktop using RMagick (ImageMagick from Ruby). (It will need some modifications to run on other desktops). 
The result so far can be seen at
http://home1.stofanet.dk/mh.homepage/files/screenshot.png

I run it as an autostarted application and as a cron job at midnight:
In:
 crontab -e
Insert:
 @midnight       $HOME/bin/xfremind

Where $HOME/bin/xfremind is where I placed the script.

The script requires remind, RMagick http://rmagick.rubyforge.org/ (and everything RMagick depends on. On Debian, the package is named librmagick-ruby).

The script looks like:





#!/usr/bin/env ruby

require 'RMagick'

BACKGROUND_PICKTURE="background.png" #Place it at ~/.config/xfremind/background.png
NEGATE_CALENDAR = true
screen_width = 1280
screen_height = 1024

OUTPUT_DIR="#{ENV['HOME']}/.config/xfremind"
unless test ?d,OUTPUT_DIR
   Dir.mkdir(OUTPUT_DIR)
end
Dir.chdir(OUTPUT_DIR)

if Object.const_defined?(:BACKGROUND_PICKTURE) && File.exist?(BACKGROUND_PICKTURE)
   background = Magick::ImageList.new(BACKGROUND_PICKTURE)
else 
   fill = Magick::GradientFill.new(0, 0, 0, 0, "#8888bb", "#333399")
   background = Magick::Image.new(screen_width, screen_height, fill)
   background = background.swirl(-360)
end

system('remind -m -b1 -p ~/.reminders | rem2ps -sthd 14 -se 10 -i -l -e > calendar.ps')  # The command that generates the postscript calendar.
calendar = Magick::ImageList.new("calendar.ps")
calendar.rotate!(90)

if Object.const_defined?(:NEGATE_CALENDAR) && (NEGATE_CALENDAR)
   calendar = calendar.negate
   wallpaper = background.composite(calendar, Magick::SouthEastGravity, Magick::ScreenCompositeOp)
else
   wallpaper = background.composite(calendar, Magick::SouthEastGravity, Magick::MultiplyCompositeOp)
end

wallpaper.write('wallpaper.png')  # This file should be selected as wallpaper.
system('killall -USR1 xfdesktop') # This reloads the XFCE4 desktop.







Kind Regards
