NAME Weather::GHCN::Fetch - Fetch station and weather data from the NOAA GHCN repository VERSION version v0.0.001 SYNOPSIS use Weather::GHCN::Fetch; Weather::GHCN::Fetch->run( \@ARGV ); See ghcn_fetch.pl -help for details. SUBROUTINES run ( \@ARGV ) 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. get_user_options ( $optfile=undef ) Fetch.pm uses get_user_options() to either get user options via Tk::GetOptions -- if it is installed -- or via Getopt::Long. get_user_options_no_tk ( $optfile=undef ) 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. The $optfile argument is only used by get_user_options_no_tk. get_user_options_tk ( $optfile=undef ) 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 $optfile argument specifies a filename which Tk::GetOptions can use to store or load options. valid_report_type ($rt, \@opttable) This function is used to valid the report type. Valid values are defined in the built-in Tk options table, which can be obtained by calling: my @opttable = ( Weather::GHCN::Options->get_tk_options_table() ); deabbrev_report_type ($rt) The report types supported by the -report option can be abbrevated, so long as the abbrevation is unambiquous. For example, 'daily' can be abbreviated to 'dail', 'dai', 'da', or even 'd'. This function takes a (possibly abbreviated) report type and returns an unabbreviated report type.
