MythWeather Grabber Script Format
MythWeather grabber scripts are small executable perl, python, or binary applications which query online sources of weather and return it in a format parseable by MythWeather. This page documents the current format required of the grabber scripts to function.
The Version Command (-v)
All grabber scripts must return an identifying string when run with the '-v' argument. The command returns a comma separated list of the script name, script version, author, and author's email, and output must end with a newline character.
#./bbccurrentxml.pl -v BBC-Current-XML,0.2,Stuart Morgan,firstname.lastname@example.org
The Timeout Command (-T)
All grabber scripts must return two timeout values when run with the '-T' argument. The command returns a comma separated list of information lifetime, and web response timeout, in seconds.
#./bbccurrentxml.pl -T 7200,30
The Field List Command (-t)
All grabber scripts must return a list of available data fields, one per line, when run with the '-t' argument.
#./bbccurrentxml.pl -t cclocation station_id copyright observation_time weather temp relative_humidity wind_dir pressure visibility weather_icon appt wind_spdgst
The Location Search Command (-l <location>)
All grabber scripts must return a list of possible location matches, one per line, when run with the '-l' argument. The matches are an identifying string to be used with the data string, and a description, separated by a double colon.
#./bbccurrentxml.pl -l Cincinnati 407::Cincinnati, Ohio 3231::Cincinnati/Northern Kentucky International, Kentucky
The Directory Option (-d)
use unknown... for radar image downloads?
The Data Command (-u <unit system> <location string>)
A grabber script with called without any of the above options must take a unit system, and a location, and return data for each of the fields listed by the '-t' command. The Location will be that provided by the '-l' commands, and the unit system will be one of 'SI' or 'ENG'. Data is returned, one value per line, separated from the identifying string by a double colon.
