  Pre/Post scene commands in OSX (Message 1 to 5 of 5)

I am trying to use the Pre/Post Scene Commands in an INI file but I can't
get them to work.  Do they work in OS X or am I doing something wrong?  Any
advice would be greatly appreciated.  I am attempting to shell out to the
OS to create a file before the rendering begins and overwrite it after it
finishes.

Pre_Scene_Command=printf "working" > ../../povProj/status2.txt
Post_Scene_Command=printf "done" > ../../povProj/status2.txt


I don't know a lot of UNIX but these lines do work when pasted into the
terminal.  I apologize if this has been asked before.   I am new to the
list (just signed up) and I couldn't find any past references to it.

You cannot access the Unix command-line from a regular Mac application. If
you want to control POV-Ray via the command-line, I would recommend to
compile a Unix command-line version and not use the GUI version.

Thanks, Thorsten, for your rapid response to my question.  As a follow up,
perhaps I could ask another question: do the post/pre commands do anything
presently on the Mac version?  For instance, could they launch a script via
applescript?  I am just trying to explore other ways of signaling another
applescript that a rendering job is complete so that I can start another
job.  This can probably all be done in applescript but having POV-Ray
signal when it was done seemed the easiest and most direct approach.
Thanks again, Chris

No, sorry!

There is currently no way AppleScript can start a render, sorry!

PS: Both features do have a rather high priority on the Mac GUI todo list,
check again when 3.6.2 comes out in a few month, maybe I will have had the
time to add it until then.  It isn't all that much to do on the Mac side...

Thorsten,

Thanks for the info and thanks for letting me know where in the todo list
these GUI features stand.  I am looking forward to version 3.6.2 especially
if you have time to add these features but I know how busy you must be!

  Actually, I can start a Render job using Applescript by sending the
keyboard shortcut with the following GUI code.

 tell application "System Events"
  tell process "POV-Ray Mac 3.6"
   keystroke "r" using {command down}
  end tell
 end tell

So starting a render job isn't a problem for me, but knowing when the job is
over is hard to find out.  I have even tried having POV-Ray write a file
saying "done" and having Applescript check it periodically but POV-Ray
would write it before it was done rendering completely.

Anyway, at present I am trying to install the command line UNIX version and
since I am having a few problems with that I am going to post a message on
the Unix message board.  Thanks again,
Chris
