Weather::GHCN::App::Fetch - Fetch station and weather data from the NOAA GHCN repository
version v0.0.004
use Weather::GHCN::App::Fetch; Weather::GHCN::App::Fetch->run( \@ARGV );
See ghcn_fetch.pl -help for details.
Invoke this subroutine, passing in a reference to @ARGV, in order to fetch NOAA GHCN station data or daily weather data.
See ghnc_fetch.pl -help for details.
Fetch.pm uses get_user_options() to either get user options via Tk::GetOptions -- if it is installed -- or via Getopt::Long.
This function obtains user options from @ARGV by calling Getopt::Long GetOptions using a list of option definitions obtained by calling Weather::GHCN::Options-get_getopt_list()>. The options (and their values) are extracted from @ARGV and put in a hash, a reference to which is then returned.
This function is called when the GUI is not being used. The $optfile argument, if provided, is assumed to be a file saved from a GUI invocation and will be eval'd and used as the options list.
This function returns a reference to a hash of user options obtained by calling Tk::Getopt. This may launch a GUI dialog to collect the options.
The optional $optfile argument specifies a filename which Tk::GetOptions can use to store or load options.
