Created page with "This script can be used to continuously check the modification timestamp on a file (any format, although this example assumes it's a PDB file), and re-loads it whenever the times..."

New page

This script can be used to continuously check the modification timestamp on a file (any format, although this example assumes it's a PDB file), and re-loads it whenever the timestamp changes. As written it is intended to be started from the command line, but this is not a requirement.

= The Code =

<source lang="python">
from pymol import cmd
import threading
import time
import os
import sys

class pymol_file_monitor (object) :
def __init__ (self,
file_name,
time_wait=1) : # time in seconds between mtime check
self.file_name = file_name
self.time_wait = time_wait
self.watch = True # this can be toggled elsewhere to stop updating
self.mtime = 0
t = threading.Thread(target=self.check_file)
t.setDaemon(1)
t.start()
print "Watching file %s" % file_name

def check_file (self) :
while (self.watch) :
if (os.path.exists(self.file_name)) :
print "checking..."
mtime = os.path.getmtime(self.file_name)
if (mtime > self.mtime) :
self.mtime = mtime
print "Re-loading %s" % self.file_name
cmd.load(self.file_name, state=1)
time.sleep(self.time_wait)

if (__name__ == "pymol") :
monitor = pymol_file_monitor("status.pdb")
</source>
