6 AppConfig::Getopt - Perl5 module for processing command line arguments
7 via delegation to Getopt::Long.
8
10 use AppConfig::Getopt;
11
12 my $state = AppConfig::State->new(\%cfg);
13 my $getopt = AppConfig::Getopt->new($state);
14
15 $getopt->parse(\@args); # read args
16
18 AppConfig::Getopt is a Perl5 module which delegates to Johan Vroman's
19 Getopt::Long module to parse command line arguments and update values
20 in an AppConfig::State object accordingly.
21
22 AppConfig::Getopt is distributed as part of the AppConfig bundle.
23
25 USING THE AppConfig::Getopt MODULE
26 To import and use the AppConfig::Getopt module the following line
27 should appear in your Perl script:
28
29 use AppConfig::Getopt;
30
31 AppConfig::Getopt is used automatically if you use the AppConfig module
32 and create an AppConfig::Getopt object through the getopt() method.
33
34 AppConfig::Getopt is implemented using object-oriented methods. A new
35 AppConfig::Getopt object is created and initialised using the new()
36 method. This returns a reference to a new AppConfig::Getopt object. A
37 reference to an AppConfig::State object should be passed in as the
38 first parameter:
39
40 my $state = AppConfig::State->new();
41 my $getopt = AppConfig::Getopt->new($state);
42
43 This will create and return a reference to a new AppConfig::Getopt
44 object.
45
46 PARSING COMMAND LINE ARGUMENTS
47 The "parse()" method is used to read a list of command line arguments
48 and update the state accordingly.
49
50 The first (non-list reference) parameters may contain a number of
51 configuration strings to pass to Getopt::Long::Configure. A reference
52 to a list of arguments may additionally be passed or @ARGV is used by
53 default.
54
55 $getopt->parse(); # uses @ARGV
56 $getopt->parse(\@myargs);
57 $getopt->parse(qw(auto_abbrev debug)); # uses @ARGV
58 $getopt->parse(qw(debug), \@myargs);
59
60 See Getopt::Long for details of the configuartion options available.
61
62 A Getopt::Long specification string is constructed for each variable
63 defined in the AppConfig::State. This consists of the name, any
64 aliases and the ARGS value for the variable.
65
66 These specification string are then passed to Getopt::Long, the
67 arguments are parsed and the values in the AppConfig::State updated.
68
69 See AppConfig for information about using the AppConfig::Getopt module
70 via the getopt() method.

84 Many thanks are due to Johan Vromans for the Getopt::Long module. He
85 was kind enough to offer assistance and access to early releases of his
86 code to enable this module to be written.
