This is the same as giving a duration of 0. + +If a duration is given, webgps.py runs for this duration and generates the +tracks of the GPS satellites in view. If the duration is the letter 'c', +the script never exits and continuously updates the skyview. + +webgps.py generates two files: a HTML5 file that can be browsed, and a +JavaScript file that contains the drawing commands for the skyview. The HTML5 +file auto-refreshes every five minutes. The generated file names are +"gpsd-<duration>.html" and "gpsd-<duration>.js". + +If webgps.py is interrupted with Ctrl-C before the duration is over, it saves +the current tracks into the file "tracks.p". This is a Python "pickle" file. +If this file is present on start of webgps.py, it is loaded. This allows to +restart webgps.py without losing accumulated satellite tracks. +""" import time, calendar, math, socket, sys, os, select, pickle try: |
