    ...
}

DESCRIPTION

Utility functions to help parse AGA format files.

Importable functions are:

is_ID
is_Rank
is_Rating
is_Rank_or_Rating
normalize_ID
Rank_to_Rating

is_ID($id);

Returns true if $id is a valid AGA ID, otherwise returns false.

is_Rank($rank);

Returns true if $rank is a valid AGA rank like '3D' or '10k', otherwise returns false.

is_Rating($rating);

Returns true if $rating is a valid AGA numeric rating, otherwise returns false.

is_Rank_or_Rating($rating);

Returns is_Rank($rating) or is_Rating($rating)

$id = normalize_ID($id);

Normalizes IDs. All lower-case letters are converted to upper case. If the ID starts with a digit (e.g. directly from a TDList file), it is pre-pended with 'USA'. Preceding zeros (defined as any zero immediately following a non-digit and followed by a digit) are removed (u01x002 becomes U1X2). All remaining sequences of zeros are shortened to a single zero (u003x00 becomes U3X0).

$rank = Rank_to_Rating($rank);

Converts a $rank (like 3D or 10k) to a numeric rating. If $rank is already a Rating, just returns it unchanged. Dan range adds 0.5, while kyu ranges subtract 0.5 (so 3D = 3.5 and 10K = -10.5). Can throw an exception if $rank is not recognized as a rank or a rating.
