NAME

       Mail::Box::Parser::Perl - reading messages from file using Perl

INHERITANCE

        Mail::Box::Parser::Perl
          is a Mail::Box::Parser
          is a Mail::Reporter

SYNOPSIS

DESCRIPTION

       The "Mail::Box::Parser::Perl" implements parsing of messages in Perl.  This may be a
       little slower than the "C" based parser Mail::Box::Parser::C, but will also work on
       platforms where no C compiler is available.

       Extends "DESCRIPTION" in Mail::Box::Parser.

METHODS

       Extends "METHODS" in Mail::Box::Parser.

   Constructors
       Extends "Constructors" in Mail::Box::Parser.

             file               Mail::Box::Parser  undef
             filename           Mail::Box::Parser  <required>
             fix_header_errors                     <false>
             log                Mail::Reporter     'WARNINGS'
             mode               Mail::Box::Parser  'r'
             trace              Mail::Reporter     'WARNINGS'
             trusted                               <false>

           file => FILE-HANDLE
           filename => FILENAME
           fix_header_errors => BOOLEAN
             When header errors are detected, the parsing of the header will be stopped.  Other
             header lines will become part of the body of the message.  Set this flag to have the
             erroneous line added to the previous header line.

           log => LEVEL
           mode => OPENMODE
           trace => LEVEL
           trusted => BOOLEAN
             Is the input from the file to be trusted, or does it require extra tests.  Related
             to Mail::Box::new(trusted).

   The parser
       Extends "The parser" in Mail::Box::Parser.

       $obj->filename()
           Inherited, see "The parser" in Mail::Box::Parser

       $obj->fixHeaderErrors( [BOOLEAN] )
           If set to "true", parsing of a header will not stop on an error, but attempt to add
           the erroneous this line to previous field.  Without BOOLEAN, the current setting is
           returned.

           example:

            $folder->parser->fixHeaderErrors(1);
            my $folder = $mgr->open('folder', fix_header_errors => 1);

DIAGNOSTICS

       Warning: File $filename changed during access.
           When a message parser starts working, it takes size and modification time of the file
           at hand.  If the folder is written, it checks whether there were changes in the file
           made by external programs.

           Calling Mail::Box::update() on a folder before it being closed will read these new
           messages.  But the real source of this problem is locking: some external program (for
           instance the mail transfer agent, like sendmail) uses a different locking mechanism as
           you do and therefore violates your rights.

       Error: Package $package does not implement $method.
           Fatal error: the specific package (or one of its superclasses) does not implement this
           method where it should. This message means that some other related classes do
           implement this method however the class at hand does not.  Probably you should
           investigate this and probably inform the author of the package.

       Warning: Unexpected end of header in $source: $line
           While parsing a message from the specified source (usually a file name), the parser
           found a syntax error.  According to the MIME specification in the RFCs, each header
           line must either contain a colon, or start with a blank to indicate a folded field.
           Apparently, this header contains a line which starts on the first position, but not
           with a field name.

           By default, parsing of the header will be stopped.  If there are more header lines
           after the erroneous line, they will be added to the body of the message.  In case of
           new(fix_headers) set, the parsing of the header will be continued.  The erroneous line
           will be added to the preceding field.
