Sets $opt_* as a side effect. - getopt('oDI', \%opts); # -o, -D & -I take arg. Values in %opts - getopts('oif:'); # -o & -i are boolean flags, -f takes an argument - # Sets $opt_* as a side effect. - getopts('oif:', \%opts); # options as above. Values in %opts - -=head1 DESCRIPTION - -The getopt() function processes single-character switches with switch -clustering. Pass one argument which is a string containing all switches -that take an argument. For each switch found, sets $opt_x (where x is the -switch name) to the value of the argument if an argument is expected, -or 1 otherwise. Switches which take an argument don't care whether -there is a space between the switch and the argument. - -The getopts() function is similar, but you should pass to it the list of all -switches to be recognized. If unspecified switches are found on the -command-line, the user will be warned that an unknown option was given. -The getopts() function returns true unless an invalid option was found. - -Note that, if your code is running under the recommended C<use strict -'vars'> pragma, you will need to declare these package variables -with "our": - - our($opt_x, $opt_y); - -For those of you who don't like additional global variables being created, getopt() -and getopts() will also accept a hash reference as an optional second argument. -Hash keys will be x (where x is the switch name) with key values the value of -the argument or 1 if no argument is specified. - -To allow programs to process arguments that look like switches, but aren't, -both functions will stop processing switches when they see the argument -C<-->. The C<--> will be removed from @ARGV. - -=head1 C<--help> and C<--version> - -If C<-> is not a recognized switch letter, getopts() supports arguments -C<--help> and C<--version>. If C<main::HELP_MESSAGE()> and/or -C<main::VERSION_MESSAGE()> are defined, they are called; the arguments are -the output file handle, the name of option-processing package, its version, -and the switches string. If the subroutines are not defined, an attempt is -made to generate intelligent messages; for best results, define $main::VERSION. - -If embedded documentation (in pod format, see L<perlpod>) is detected -in the script, C<--help> will also show how to access the documentation. - -Note that due to excessive paranoia, if $Getopt::Std::STANDARD_HELP_VERSION -isn't true (the default is false), then the messages are printed on STDERR, -and the processing continues after the messages are printed. This being -the opposite of the standard-conforming behaviour, it is strongly recommended -to set $Getopt::Std::STANDARD_HELP_VERSION to true. - -One can change the output file handle of the messages by setting -$Getopt::Std::OUTPUT_HELP_VERSION. One can print the messages of C<--help> -(without the C<Usage:> line) and C<--version> by calling functions help_mess() -and version_mess() with the switches string as an argument. - -=cut - -@ISA = qw(Exporter); -@EXPORT = qw(getopt getopts); -$VERSION = '1.05'; -# uncomment the next line to disable 1.03-backward compatibility paranoia -# $STANDARD_HELP_VERSION = 1; - -# Process single-character switches with switch clustering.
