NAME

       Embperl::Syntax::RTF - define syntax for RTF files

SYNOPSIS

DESCRIPTION

       Class derived from Embperl::Syntax to define the syntax for RTF files. RTF files can be
       read and written by various word processing programs. This allows you to create dynamic
       wordprocessing documents or let process serial letters thru Embperl.

       Currently Embperl regocnices the fields "DOCVARIABLE", "MERGEFIELD" and "NEXT".
       Variablenames are resolved as hash keys to $param[0] e.g. "foo.bar" referes to
       "$param[0]{foo}{bar}", the @param Array can by set via the "param" parameter of the
       "Execute" function. "NEXT" moves to the next element of the @param array. If the end of
       the document is reached, Embperl repeats the document until all element of @param are
       processed. This can for example be use to tie a database table to @param and generate a
       serial letter.

       NOTE: Extenting this syntax to support full Embperl support (like embedding Perl into RTF
       file is planned, but not implemented yet)

Example for generating a serial letter from a database

         use DBIx::Recordset ;
         use Embperl ;

         *set = DBIx::Recordset -> Search({'!DataSource' => $db, '!Table' => 'address', '!WriteMode' => 0}) ;

         die DBIx::Recordset -> LastError if (DBIx::Recordset -> LastError) ;

         Embperl::Execute ({'inputfile' => 'address.rtf', param => \@set, syntax => 'RTF'}) ;

         # if your database table contains fields 'name' and 'street' you can now simply insert a
         # fields call 'name' and 'street' in your RTF file and Embperl will repeat the document
         # until all records are outputed

Methods

       Embperl::Syntax::RTF defines the following methods:

   Embperl::Syntax::RTF -> new  /  $self -> new
       Create a new syntax class. This method should only be called inside a constructor of a
       derived class.

   AddRTFCmd ($cmdname, $procinfo)
       Add a new RTF command with name $cmdname and use processor info from $procinfo. See
       Embperl::Syntax for a definition of procinfo.

   AddRTFCmdWithEnd ($cmdname, $endname, $procinfo)
       Add a new RTF command with name $cmdname and use processor info from $procinfo. Addtionaly
       specify that a matching $endname RTF command must be found to end the block, that is
       started by this RTF command.  See Embperl::Syntax for a definition of procinfo.

   AddRTFCmdBlock ($cmdname, $endname, $procinfostart, $procinfoend)
       Add a new RTF command with name $cmdname and and a second RTF command $endname which ends
       the block that is started by $cmdname.  Use processor info from $procinfo.  See
       Embperl::Syntax for a definition of procinfo.
