Hi,

I'm extending Perl::Pie package to include more deterministic rules that can be triggered in some certain time moments (new seconds, every 5 secs, etc...). Rules consists of conditions that must be true, so actions in the list get executed.

I've add some simple time related functions (new_second, new_hour, ...) and variables ($Week_day, $Day, $Hour) in the additional time.pl file. I've included it in main file with

require 'time.pl';

and declared all functions in it as main::function. I can use them easily in main program, but have problems if I try to use those functions as parts of condition or actions of rules...

I try to use them as "eval $str" from some Perl::PIE package, where $str is written in xml rules config file, but it seems that it is not working at all. I think I need to run them in "context of the main" program but this is obviously not happening... I've debugged code and it doesn't get into function at all. I must be missing some basic things about dealing with global variables and functions...

I have this in xml config : 

  <rule name="print status every 5 secs">
   <condition attribute='main::new_second(5)' type="time" trigger="1">
+1</condition>
   <action attribute="\n****************print status every 5 secs: New
+_Second: Weekday:$Wday Time:$Hour:$Minute:$Second Time_Now:$Time_Now 
+Date:$Mday/$Month/$Year" type="print">1</action>
  </rule>

and when I try to eval('main::new_second(5)') nothing happens, if I do the same from main program it works...

I'd kindly as for some help or some pointers to similar solutions ...

Thanks in advance,

regards,

Rob.
