I have a .qtz that loads the last line of the latest .log file, to show the currently played song from a player.

Here is the source, with 2 .log files as an example: LastTrack.zip (read the instructions inside the .zip)

It works, but manually. You need to run it again from the Viewer to get the last played song. If you don´t do that, it always shows the same text, even if in the .log was a new track.

I would like to know if there is a way to make it work automatically (I have tried with LFO and Pulse with no results and making the script outputting some errors).

I have tried unplugging the LFO/Pulse and Enable/Disable by hand continuosly both Command Line Tool patches.

When doing it in "Get lastest .log file" patch, it outputted this error:

An exception was raised:

* -[NSConcreteTask terminationStatus]: task still running

When doing it in "Get the last line of the .log file" patch, it outputted this error (i think is the same):

An exception was raised:

Thank you in advance for your help.

The Command Line Tool patch updates only when its input ports change. So, in your case, you could attach something that changes periodically (the Signal private patch, for example) to an unused input, such as "Standard In".

  • Hi Smokris, thank you so much for your answer. I have been searching for that private patch, but I haven´t found it. My QC version is 4.0. Have you tried it with the LastTrack.qtz and it works? (remember I said before that i.e. the LFO to the CLT "Standard In" makes the script crashes after a short time running) Thank you again. – Pablo Nov 09 '10 at 20:36
  • Go to the Quartz Composer menu, hold Option, then click Preferences. Then select the new "(System)" tab, and enable the QCShowPrivatePatches setting. Restart QC, and you should see `Signal`. I did test it with `Signal`, and it does seem to work. – smokris Nov 09 '10 at 21:27
  • Hi, after trying several configurations, It seems to work, with 2 Signal patches (Mode: Every 5 seconds), attached to both "Enable" in CTL patches. The issue now is the same than with the LFO/Pulse: the script stops/crashes after a short period of time (30sec, 1 min, whatever), and when you run it again, the text in the Viewer is showed in a random scale. It gets normal when you restart LastTrack. Can you give me an idea about how did you make it work in your test, please? – Pablo Nov 09 '10 at 22:35
  • Regarding the random viewport scaling --- UGH, I forgot how awful the `Command Line Tool` patch is. I'm working on an update to Kineme FileTools --- use that instead, when it's ready. – smokris Nov 09 '10 at 23:20
  • Ok Smokris, I´ll wait till the update, if there´s no solution at this moment. How long would it take? The stopping/crashing issue is another CLT bug also? Thank you so much. – Pablo Nov 09 '10 at 23:29
  • Does anyone knows why this composition crashes after a short time running, please? – Pablo Nov 11 '10 at 09:14
