Sublets\015\012\015\012Sublets are small Ruby scripts that provide the data for the statusbar. They are run in an embedded Ruby interpreter and are well included in the main loop of subtle. Every sublet must either provide an update interval (in seconds) and will be updated accordingly or a file to watch. \015\012_The default update interval is 60s._\015\012\015\012h2. Types\015\012\015\012Currently there are two types of sublets:\015\012* sublets that are updated in a given interval\015\012* sublets that are updated when a file is modified (Via inotify. Data\015\012\015\012The sublet data can be either of type String or Fixnum. Strings are directly displayed and Fixnums will be shown as a small meter.\015\012\015\012\015\012h2. Example\015\012\015\012Below is the code of a shipped sublet that displays the time. It should be really straight forward:\015\012\015\012class Clock < Sublet\015\012 def initialize\015\012 self.interval = 60 # Set interval time\015\012 end\015\012\015\012 def run\015\012 self.data = Time.now().strftime("%d%m%y%H%M") # Set data\015\012 end\015\012end\015\012
\015\012\015\012Interval and data can be updated via setter/getter functions.\015\012\015\012Another example for the inotify sublet which is also included within subtle:\015\012\015\012class Notify < Sublet\015\012 def initialize\015\012 self.path = "/tmp/watch"\015\012 end\015\012\015\012 def run\015\012 file = ""\015\012\015\012 File.open(self.path, "r") do |f|\015\012 file = f.read\015\012 end\015\012\015\012 self.data = file.chop || "subtle"\015\012 end\015\012end\015\012
