I wrote a little better version:
def do_desktop(desktop, commands, seconds_to_wait):
desktop_command = (switch_desktop + desktop).split()
if seconds_to_wait == 0:
seconds_to_wait = 10
check_call(desktop_command)
for command_arr in commands:
command = command_arr[0].split()
log_directory = command_arr[1]
directory = command_arr[2]
if not log_directory:
log_directory = '/dev/null'
log_file_name = log_directory.replace('%T', strftime('%F_%R'))
with open(log_file_name, 'w') as log_file:
Popen(command, stdout = log_file, cwd = directory, stderr = STDOUT)
sleep(seconds_to_wait)
When there is no log_directory I set it to '/dev/null': that makes the
code a little bit cleaner.
And everything is now fetched from the database:
for desktop in cursor.execute(select_desktops).fetchall():
desktop_name = desktop[0]
desktop_value = desktop[1]
desktop_wait = desktop[2]
commands = cursor.execute(select_commands, [desktop_name]).fetchall()
do_desktop(desktop_value, commands, desktop_wait)
