purple/answerscripts.sh

   1 #!/bin/bash
   2 #
   3 #       This file is called for every message received by libpurple clients (pidgin,finch,...)
   4 #               - You can try to rewrite this script in PERL or C for better performance (or different platform) - let me know
   5 #               - On M$ Windows answerscripts.exe from libpurple directory will be called instead of this script
   6 #
   7 #       Maybe you will want to add more hooks for receiving messages, so i've made following script
   8 #       - It just executes all +x files in answerscripts.d directory so you should do your magic there
   9 #       - To disable some of those scripts simply use: chmod -x ./script
  10 #       - There is some basic structure, which means that all scripts should start their names with two-digit number
  11 #       - Files are executed in order specified by those numbers and some numbers have special meanings:
  12 #               - AB?!_ scripts without numbers are NOT executed!
  13 #               - 00    executed immediately, zero or single line output (parallel async processing)
  14 #               - 01-48 executed immediately, multiline output (serial processing)
  15 #               - 49    delay script (adds random delay to emulate human factor, no user scripts at this level!)
  16 #               - 50    executed after delay, zero or single line output (parallel async processing)
  17 #               - 51-79 executed after delay, multiline output (serial processing)
  18 #               - 80-99 reserved for future
