Games::Go::AGA::Parse::TDList - Parses lines from an AGA TDLISTlist

VERSION

version 0.042

SYNOPSIS

use Games::Go::Parse::TDList;

            

              
              
my $parser = Games::Go::AGA::Parse::TDList->new;
while (my $line = <$tdlist_fh>) {
    my $hash = $parser->parse($line); # ref to a hash
    ...
}
            
          

DESCRIPTION

A parser to break out and return fields of a line from an AGA TDListN.txt file. The fields are usually:

            

              
              
last_name
first_name
id
membership
rank
date
club
state
extra
            
          

but some fields could be empty ('').

Note that the rank field may be either rank format (3K, 4d, etc) or a numerical rating (from -100 to +20 with a gap from -1 to +1). Rank format implies less certainty in the accuracy of the rank. The Rank_to_Rating function in Games::Go::AGA::Parse::Utils can be used to force the numerical format.

METHODS

$parser = Games::Go::AGA::Parse::TDList->new;

Creates a new parser object.

$parser = $parser->filename( ['new_name'])

Get/set a filename (used in error messages)

$file_handle = $parser->filename( [$new_file_handle ])

Get/set a file handle (used in error messages)

%result_hash = $parser->parse_line('a TDListN line')

%result_hash = $parser->parse()

Parses a single line from the TDListN.txt file and returns a hash with the fields as listed in as_hash. Calling this function removes any field results from previous lines.

%as_hash = $parser->as_hash()

Retuns the parsed line as a hash. Missing fields will be empty strings (''). The hash keys are

            

              
              
(
    last_name  => 'last name of player',
    first_name => 'first name of player',
    id         => 'player ID',
    membership => 'AGA membership type (if any)',
    rank       => 'player's rank or rating',
    date       => 'date player's membership is valid until',
    club       => 'club player usually plays at',
    state      => 'state player lives in',
    extra      => 'any extra stuff',
)
            
          

In scalar context, returns a reference to the hash.

@as_array = $parser->as_array()

Retuns the parsed line as an array. Missing fields will be empty strings (''). The order is:

            

              
              
(
    last_name
    first_name
    id
    membership
    rank
    date
    club
    state
    extra
)
            
          

In scalar context, returns a reference to the array.

$field_by_name = $parser-> < name >

Individual fields may be set or retrieved by name. E.g:

            

              
              
$last_name = $parser->last_name
 . . .
$parser->rank('4d');
            
          

OPTIONS

Options to the ->new method are:

filename => 'file name'

handle => $file_handle

These are not required to create a parser, but if supplied, error exceptions will include more useful information.
