python script

LinuxLala · 03-25-2004, 11:08 PM

Hi all

I am interested in making a python script which would after the specified interval of time play a midi file.

It's like an alarm clock but the only catch is that I want it to keep repeating after say every 15 minute or so.

So, if I run the script, it plays that file(the alarm sound) after every 15 minutes.

Guide me ppl. May the forces be with you.

$ man crontab

It is the standard tool for doing such things, and I think you'll like it once you get the hang of the syntax.

'at' is also excellent for one-time scheduling (which I realize you're not doing here, but it's still good to know):

Code:

$ at now + 30 min <enter>
at> _

Otherwise, if you insist on Python, you can do something like (note: I'm a Perlmonkey when it comes to scripting, so it's pseudo-code and I'm assuming Python has a sleep function; possibly as an add-on module(?)):

Code:

while (1) {
    midiplayer /path/to/music.midi;
    sleep 60*15;
}

I don't know what program is good for playing .midis, but I assume there are tens if not hundreds

HTH.

Hey, thanks rkef.

I'll still try it first in Python and then in Perl. So maybe I'll get back with my hiccups.

Cheers.

It'd be a great help if someone out here can give me a step-by-step to doing this.

What distro are you using? Check if you have a crond process running.

Something like this

Code:

#!/usr/bin/python
import os
import time
 
while(1):
        time.sleep(15)
        os.system("pmidi my.mid")

I'll see and then I'll get back.

Hi.

I am using RH 9. Could this be possible if I wish to play an mp3 or a wav file instead of just midi.

kooch · 03-30-2004, 06:39 PM

change the double quoted text in this line : os.system("pmidi my.mid")
to execute anything you want.

LinuxLala · 04-05-2004, 02:12 AM

Ok. So I have RH9 and still getting nowhere.

I have checked and crond services are running. Kindly guide me in making this script.

Code:

#!/usr/bin/python
import os
import time
 
while(1):
        time.sleep(15)
        os.system("mpeg123 my_mp3.mp3")

Now save the file as my_file.py and run it as so: python my_file.py

Enjoy!

Please sort this out for me. When I type at the console
kmidi abc.mid
it says

Xlib: extension "GLX" missing on display ":0.0".
/dev/dsp doesn't support 4096-byte buffer fragments

But it starts playing.

But when I run the python script it says

Xlib: extension "GLX" missing on display ":0.0".
/dev/dsp doesn't support 4096-byte buffer fragments
Kmidi:Problem with PIPE_INT_WRITE due to:Broken pipe
Xlib: extension "GLX" missing on display ":0.0".
/dev/dsp doesn't support 4096-byte buffer fragments

It opens up kmidi but dies not play the file, WHY?

LinuxLala · 04-06-2004, 05:17 AM

I also realised that I could not specify the path to the midi file in the script so I moved the file to he directory where the script is.

Hi all. I got it. Thanks for your time and support.

Thank you.
