libmateweather is a libgnomeweather fork.

libmateweather is a library to access weather information from online
services for numerous locations.

libmateweather isn't supported in the devel platform, which means OS vendors 
won't guarantee the API/ABI long-term, but authors of open source apps
should feel free to use libmateweather as users can always recompile against
a new version.  

To use libmateweather in your code, you need to define the 
MATEWEATHER_I_KNOW_THIS_IS_UNSTABLE preprecessor symbol, e.g. by adding
-DMATEWEATHER_I_KNOW_THIS_IS_UNSTABLE to your CFLAGS.


HOW TO TRANSLATE THE DEFAULT LOCATION DATA
------------------------------------------

To translate the default location, enter the data for the largest city on your
locale as folows: (Location Data for en_US.UTF-8: «Washington, D.C, US»)

    msgid "'DEFAULT_LOCATION'"
    msgstr "'Washington'"

    msgid "'DEFAULT_CODE'"
    msgstr "'KOCW'"

    msgid "'DEFAULT_ZONE'"
    msgstr "'America/New_York'"

    msgid "'DEFAULT_RADAR'"
    msgstr "' '"

    msgid "'DEFAULT_COORDINATES'"
    msgstr "'35.570557 -77.049721'"

You can retrieve the required data if you have set your location on the clock
panel applet:

    $ dconf read /org/mate/panel/objects/clock/prefs/cities 
    ['<location name="" city="Washington" timezone="America/New_York"
    latitude="35.570557" longitude="-77.049721" code="KOCW" current="false"/>']
