9 Providing the expansion context early
10 use Mail::SPF::MacroString;
11
12 my $macrostring = Mail::SPF::MacroString->new(
13 text => '%{ir}.%{v}._spf.%{d2}',
14 server => $server,
15 request => $request
16 );
17
18 my $expanded = $macrostring->expand;

20 Providing the expansion context late
21 use Mail::SPF::MacroString;
22
23 my $macrostring = Mail::SPF::MacroString->new(
24 text => '%{ir}.%{v}._spf.%{d2}'
25 );
26
27 my $expanded1 = $macrostring->expand($server, $request1);
28
29 $macrostring->context($server, $request2);
30 my $expanded2 = $macrostring->expand;
31
33 An object of class Mail::SPF::MacroString represents a macro string
34 that can be expanded to a plain string in the context of an SPF
35 request.
36
37 Constructor
38 The following constructor is provided:
39
40 new(%options): returns Mail::SPF::MacroString
41 Creates a new SPF record macro string object.
42
43 %options is a list of key/value pairs representing any of the
44 following options:
45
46 text
47 Required. The unexpanded text of the new macro string.
48
49 server
50 The Mail::SPF::Server object that is to be used when expanding
51 the macro string. A server object need not be attached
52 statically to the macro string; it can be specified dynamically
53 when calling the "expand" method.
54
55 request
56 The Mail::SPF::Request object that is to be used when expanding
57 the macro string. A request object need not be attached
58 statically to the macro string; it can be specified dynamically
59 when calling the "expand" method.
60
61 is_explanation
62 A boolean denoting whether the macro string is an explanation
63 string obtained via an "exp" modifier. If true, the "c", "r",
64 and "t" macros may appear in the macro string, otherwise they
65 may not, and if they do, a Mail::SPF::EInvalidMacro exception
66 will be thrown when the macro string is expanded. Defaults to
67 false.
68
69 Instance methods
70 The following instance methods are provided:
71
72 text: returns string
73 Returns the unexpanded text of the macro string.
74
75 context($server, $request): throws Mail::SPF::EOptionRequired
76 Attaches the given Mail::SPF::Server and Mail::SPF::Request objects
77 as the context for the macro string.
78
79 expand: returns string; throws Mail::SPF::EMacroExpansionCtxRequired,
80 Mail::SPF::EInvalidMacroString, Mail::SPF::Result::PermError
81 expand($server, $request): returns string; throws
82 Mail::SPF::EMacroExpansionCtxRequired, Mail::SPF::EInvalidMacroString,
83 Mail::SPF::Result::PermError
84 Expands the text of the macro string using either the context
85 specified through an earlier call to the "context()" method, or the
86 given context, and returns the resulting string. See RFC 4408, 8,
87 for how macros are expanded.
88
89 is_explanation: returns boolean
90 Returns true if the macro string is an explanation string obtained
91 via an "exp" modifier. See the description of the "new"
92 constructor's "is_explanation" option.
93
94 stringify: returns string
95 Returns the expanded text of the macro string if a context is
96 attached to the object. Returns the unexpanded text otherwise.
97 You can simply use a Mail::SPF::MacroString object as a string for
98 the same effect, see "OVERLOADING".
99
101 If a Mail::SPF::MacroString object is used as a string, the "stringify"
102 method is used to convert the object into a string.
