NAME
       Mail::SPF::MacroString - SPF record macro string class
SYNOPSIS
   Providing the expansion context early
           use Mail::SPF::MacroString;
           my $macrostring = Mail::SPF::MacroString->new(
               text    => '%{ir}.%{v}._spf.%{d2}',
               server  => $server,
               request => $request
           );
           my $expanded = $macrostring->expand;
   Providing the expansion context late
           use Mail::SPF::MacroString;
           my $macrostring = Mail::SPF::MacroString->new(
               text    => '%{ir}.%{v}._spf.%{d2}'
           );
           my $expanded1 = $macrostring->expand($server, $request1);
           $macrostring->context($server, $request2);
           my $expanded2 = $macrostring->expand;
DESCRIPTION
       An object of class Mail::SPF::MacroString represents a macro string
       that can be expanded to a plain string in the context of an SPF
       request.
   Constructor
       The following constructor is provided:
       new(%options): returns Mail::SPF::MacroString
           Creates a new SPF record macro string object.
           %options is a list of key/value pairs representing any of the
           following options:
           text
               Required.  The unexpanded text of the new macro string.
           server
               The Mail::SPF::Server object that is to be used when expanding
               the macro string.  A server object need not be attached
               statically to the macro string; it can be specified dynamically
               when calling the "expand" method.
           request
               The Mail::SPF::Request object that is to be used when expanding
               the macro string.  A request object need not be attached
               statically to the macro string; it can be specified dynamically
               when calling the "expand" method.
           is_explanation
               A boolean denoting whether the macro string is an explanation
               string obtained via an "exp" modifier.  If true, the "c", "r",
               and "t" macros may appear in the macro string, otherwise they
               may not, and if they do, a Mail::SPF::EInvalidMacro exception
               will be thrown when the macro string is expanded.  Defaults to
               false.
   Instance methods
       The following instance methods are provided:
       text: returns string
           Returns the unexpanded text of the macro string.
       context($server, $request): throws Mail::SPF::EOptionRequired
           Attaches the given Mail::SPF::Server and Mail::SPF::Request objects
           as the context for the macro string.
       expand: returns string; throws Mail::SPF::EMacroExpansionCtxRequired,
       Mail::SPF::EInvalidMacroString, Mail::SPF::Result::PermError
       expand($server, $request): returns string; throws
       Mail::SPF::EMacroExpansionCtxRequired, Mail::SPF::EInvalidMacroString,
       Mail::SPF::Result::PermError
           Expands the text of the macro string using either the context
           specified through an earlier call to the "context()" method, or the
           given context, and returns the resulting string.  See RFC 4408, 8,
           for how macros are expanded.
       is_explanation: returns boolean
           Returns true if the macro string is an explanation string obtained
           via an "exp" modifier.  See the description of the "new"
           constructor's "is_explanation" option.
       stringify: returns string
           Returns the expanded text of the macro string if a context is
           attached to the object.  Returns the unexpanded text otherwise.
           You can simply use a Mail::SPF::MacroString object as a string for
           the same effect, see "OVERLOADING".
OVERLOADING
       If a Mail::SPF::MacroString object is used as a string, the "stringify"
       method is used to convert the object into a string.
