6 MooseX::App::Meta::Role::Attribute::Option - Meta attribute role for
7 options
8
10 This meta attribute role will automatically be applied to all
11 attributes that should be used as options.
12
14 In your app and command classes you can use the following attributes in
15 option or parameter definitions.
16
17 option 'myoption' => (
18 is => 'rw',
19 isa => 'ArrayRef[Str]',
20 documentation => 'My special option',
21 cmd_flag => 'myopt',
22 cmd_aliases => [qw(mopt localopt)],
23 cmd_tags => [qw(Important!)],
24 cmd_env => 'MY_OPTION',
25 cmd_position => 1,
26 cmd_split => qr/,/,
27 cmd_negate => 'notoption'
28 );
29
30 cmd_flag
31 Use this name instead of the attribute name as the option name
32
33 cmd_type
34 Option to mark if this attribute should be used as an option or
35 parameter value.
36
37 Allowed values are:
38
39 · option - Command line option
40
41 · proto - Command line option that should be processed prior to other
42 options (eg. a config-file option that sets other attribues)
43 Usually only used for plugin developmemt
44
45 · parameter - Positional parameter command line value
46
47 cmd_env
48 Environment variable name (only uppercase letters, numeric and
49 underscores allowed). If variable was not specified otherwise the value
50 will be taken from %ENV.
51
52 cmd_aliases
53 Arrayref of alternative option names
54
55 cmd_tags
56 Extra option tags displayed in the usage information (in brackets)
57
58 cmd_position
59 Override the order of the parameters in the usage message.
60
61 cmd_split
62 Splits multiple values at the given separator string or regular
63 expression. Only works in conjunction with an 'ArrayRef[*]' type
64 constraint. ie. '--myattr value1,value2' with cmd_split set to ','
65 would produce an arrayref with to elements.
66
67 cmd_count
68 Similar to the Getopt::Long '+' modifier, cmd_count turns the attribute
69 into a counter. Every occurrence of the attribute in @ARGV (without any
70 value) would increment the resulting value by one
71
72 cmd_negate
73 Sets names for the negated variant of a boolean field. Only works in
74 conjunction with a 'Bool' type constraint.
75
77 These methods are only of interest to plugin authors.
78
79 cmd_check
80 Runs sanity checks on options and parameters. Will usually only be
81 executed if either HARNESS_ACTIVE or APP_DEVELOPER environment are set.
82
83 cmd_name_possible
84 my @names = $attribute->cmd_name_possible();
85
86 Returns a list of all possible option names.
87
88 cmd_name_list
89 my @names = $attribute->cmd_name_list();
90
91 Similar to cmd_name_possible this method returns a list of option
92 names, except for names set via cmd_negate.
93
94 cmd_name_primary
95 my $name = $attribute->cmd_name_primary();
96
97 Returns the primary option name
98
99 cmd_usage_name
100 my $name = $attribute->cmd_usage_name();
101
102 Returns the name as used by the usage text
103
104 cmd_usage_description
105 my $name = $attribute->cmd_usage_description();
106
107 Returns the description as used by the usage text
108
109 cmd_tags_list
110 my @tags = $attribute->cmd_tags_list();
111
112 Returns a list of tags
113
114 cmd_type_constraint_check
115 $attribute->cmd_type_constraint_check($value)
116
117 Checks the type constraint. Returns an error message if the check fails
118
119 cmd_type_constraint_description
120 $attribute->cmd_type_constraint_description($type_constraint,$singular)
121
122 Creates a description of the selected type constraint.
