Scan variables and strings. 1.2

About This File

Due to lack of global functions, we're adding more and more global variables. In some  cases after a while we find a way to do it differently, but the global variables are still there. Usually we quite afraid to delete the variable because we're not sure if the variable is not in use somewhere in code.
So, this code scans scenes and virtual devices and finds where the variable is in use.

  • Scenes displayed (blue color) by name and scene ID.
  • Virtual devices displayed (wheat color) by name, button name, device ID and button ID.

The program execution has four options:
1. Scan for all variables and display scenes and virtual devices where every variable is in use. (make sure findVar=nil and findString=nil)
2. Find where specific variable is in use by defining findVar.
3. Find where specific string (phrase) is in use by defining findString.

Some characters, called magic characters, have special meanings when used in a pattern. The magic characters are      

(     )   .   %   +   -   *   ?   [   ^  $

The character `%´ works as an escape for those magic characters. So, '%.' matches a dot; '%%' matches the character `%´ itself. You can use the escape `%´  also for all other non-alphanumeric characters. When in doubt, play safe and put an escape. For example if you're searching for string "match(" you should use "match%(".

4. To find not in use variables only. Press "start" twice within 1 second.

 

--================= User configurable parameters ============================
findVar = nil --------- Name of specific variable to search.
findString = nil ------ Any string to search.
--============================================================================

Notes:

  • In case findVar and findString are both defined, the code will scan for findString.
  • Make sure when findVar and findString  are not in use to set to nil

 

As usual hope it helps...
