NAME

6       Exporter::Declare::Specs - Import argument parser for Exporter::Declare
7

DESCRIPTION

9       Import arguments can get complicated. All arguments are assumed to be
10       exports unless they have a - or : prefix. The prefix may denote a tag,
11       a boolean option, or an option that takes the next argument as a value.
12       In addition almost all these can be negated with the ! prefix.
13
14       This class takes care of parsing the import arguments and generating
15       data structures that can be used to find what the exporter needs to
16       know.
17

METHODS

19       $class->new( $package, @args )
20           Create a new instance and parse @args.
21
22       $specs->package()
23           Get the name of the package that should do the exporting.
24
25       $hashref = $specs->config()
26           Get the configuration hash, All specified options and tags are the
27           keys. The value will be true/false/undef for tags/boolean options.
28           For options that take arguments the value will be that argument.
29           When a config hash is provided to a tag it will be the value.
30
31       @names = $specs->arguments()
32       @names = $specs->options()
33       @names = $specs->tags()
34           Get the argument, option, or tag names that were specified for the
35           import.
36
37       $hashref = $specs->argument_info()
38           Get the arguments that were specified for the import. The key is
39           the name of the argument and the value is what the user supplied
40           during import.
41
42       $hashref = $specs->option_info()
43           Get the options that were specified for the import. The key is the
44           name of the user supplied option and the value will evaluate to
45           true.
46
47       $hashref = $specs->tag_info()
48           Get the values associated with the tags used during import. The key
49           is the name of the tag and the value is an array ref containing the
50           values given to export_tag() for the associated name.
51
52       $hashref = $specs->exports()
53           Get the exports hash. The keys are names of the exports. Values are
54           an array containing the export, item specific config hash, and
55           arguments array. This is generally not intended for direct
56           consumption.
57
58       $arrayref = $specs->excludes()
59           Get the arrayref containing the names of all excluded exports.
60
61       $specs->export( $package )
62           Do the actual exporting. All exports will be injected into
63           $package.
64
65       $specs->add_export( $name, $value )
66       $specs->add_export( $name, $value, \%config )
67           Add an export. Name is required, including sigil. Value is
68           required, if it is a sub it will be blessed as a ::Sub, otherwise
69           blessed as a ::Variable.
70
71               $specs->add_export( '&foo' => sub { return 'foo' });
