NAME

Text::Annotated::Reader - a filter for annotating lines coming from a file

SYNOPSIS

            

              
              
use Text::Annotated::Reader;
my $reader = new Text::Annotated::Reader(input => 'text.in');
$reader->read();
$ra_annotated_lines = $reader->{annotated_lines};
            
          

DESCRIPTION

Text::Annotated::Reader is a subclass of Text::Filter, with as purpose the reading of lines from a file, and annotating the filename and linenumber for each line. The following issues are specific to Text::Annotated::Reader:

• The set_input() method only accepts filenames as a valid input argument. This requirement is also imposed on the input argument passed to new(), as new() invokes set_input().

• The read() method executes the input operation. run() is an alias for read().

• The reader() method builds a Text::Annotated::Reader filter with the supplied arguments, calls read() and finally returns the filter. It is thus possible to combine the whole input operation in a single statement like

  
              
  
                
                
  my $ra_annotated_lines = 
    Text::Annotated::Reader->reader(input => 'text.in')->{annotated_lines};
              
            

SEE ALSO

More info on using filters is available from Text::Filter.

Text::Annotated::Line describes annotated lines.
