Monitor file continuously
From PyMOLWiki
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
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")
