Getopt::Gen - extended module for gengetopt-like parsing.
use Getopt::Gen; $og = Getopt::Gen->new({...}); # create a new object $og->parse($filename); # parse a program specification file $og->parse(\*HANDLE); # ... or a filehandle $og->fill_in(TYPE=>'FILE',SOURCE=>$filename); # Fill in a Text::Template skeleton # + You don't need 'TYPE' and 'SOURCE' # arguments if you use a subclass # such as Getopt::Gen::cmdline_h.
Parse extended 'gengetopt'-style option files, and fill in output templates based on the parsed values.
%DEFAULT_TEMPLATE_ARGS
Default arguments for creating a new Text::Template object.
new(%args)
Creates a new Getopt::Gen object based on keyword-arguments %args.
Available keywords:
## -- basic data name=> __PACKAGE__ , # name to use for error-reporting ## -- generation-flags filename=>'cmdline', # basename of output file funcname=>'cmdline_parser', # name of parsing-function structname=>'gengetopt_args_info', # name of parser-structure longhelp=>0, # long usage line in help ? unnamed=>0, # allow non-option arguments ? reparse_action=>'error', # when an option is re-given: error|warn|clobber handle_help=>1, # whether to handle '-h' and '--help' options handle_version=>1, # whether to handle '-V' and '--version' options handle_error=>1, # whether to exit on errors
parse_options($file)
Parses an option-specification file. $file may be either a filename or an open filehandle. See optgen.perl for details on the file format.
$og->fill_in(\%args)
Generate a source file based on a skeleton using Text::Template. \%args may be used to override the default values for the Text::Template::new() and/or fill_in() methods.
Probably many.
