NAME

     gff2xml — BioWare GFF to XML converter

SYNOPSIS

     gff2xml [options] input_file [output_file]

DESCRIPTION

     gff2xml converts BioWare's GFF files (versions V3.2/V3.3 and V4.0/V4.1) into human-readable XML.  GFF are
     hierarchical data files, similar to XML in concept, but stored in binary.  As such, these files are used as
     a basis for many of the file formats found in the BioWare games.  For example, an UTC file is a GFF holding
     a template for a creature, while a GUI file is a GFF describing an in-game menu.

     Both version 3 of the format (V3.2/V3.3) and version 4 (V4.0/V4.1) are supported.  While they are similar,
     the 4th version carries several changes to make the files more efficient to read in-game.  This includes
     replacing the string field names (which map to XML tags) with numerical identifiers, resulting in converted
     XML files that are stripped of their meaning.  To compensate, this tool adds readable aliases to many of
     these numerical identifiers, giving them back their meaning.  Unfortunately, not all of them are known.
     Most notably, the identifiers introduced in Sonic Chronicles: The Dark Brotherhood and Dragon Age 2 are
     still missing.

     The changes in the minor versions (V3.2 vs. V3.3 and V4.0 vs.  V4.1) are less significant.  V3.3 simply
     changes which languages are supported, and V4.1 adds a common string table at the start of the file.  Both
     of these additions are handled transparently.

     LocStrings found in GFF V3.2 and V3.3 contain localized string data, which, depending on the game and the
     language, can be encoded in various ways.  There is no way to autodetect the specific encoding.  gff2xml
     employs a simple heuristic to combat this, but it may fail for certain strings and files.  However, there
     are options to explicitly specify the game this GFF file is from.  gff2xml will then use the correct game-
     specific encoding tables.

     Unfortunately, even these tables might not be completely correct in all cases.  Neverwinter Nights, for
     example, treated many strings as being encoded in the native encoding used for the language of the game
     installation.  This lead to many people putting non-English strings into fields tagged as language ID 0,
     nominally reserved for English.  To read these files correctly, gff2xml provides an --encoding parameter to
     override the encoding used for a specific language ID.

OPTIONS

     -h
     --help
           Show a help text and exit.
     --version
           Show version information and exit.
     --cp1252
           Read GFF4 strings as Windows CP-1252.  Usually, strings in version 4 of the GFF format are encoded in
           little-endian UTF-16.  But some files store them as Windows CP-1252 instead.  Since there's no clean
           way to autodetect the different encoding, this switch manually selects Windows CP-1252.  This option
           only concerns strings embedded in GFF4 files, not GFF3 LocStrings.
     --nwnpremium
           The GFF files found in the encrypted HAK files of Neverwinter Nights premium modules are deliberately
           broken.  This options tells gff2xml to work around the brokenness.
     --nwn
           Read LocStrings in an encoding appropriate for Neverwinter Nights.
     --nwn2
           Read LocStrings in an encoding appropriate for Neverwinter Nights 2.
     --kotor
           Read LocStrings in an encoding appropriate for Knights of the Old Republic.
     --kotor2
           Read LocStrings in an encoding appropriate for Knights of the Old Republic II.
     --jade
           Read LocStrings in an encoding appropriate for Jade Empire.
     --witcher
           Read LocStrings in an encoding appropriate for The Witcher.
     --dragonage
           Read LocStrings in an encoding appropriate for Dragon Age: Origins.
     --dragonage2
           Read LocStrings in an encoding appropriate for Dragon Age II.
     --encoding str
           Override an encoding.  The string has to be of the form n=encoding, for example 0=cp-1252 to override
           the encoding of the (ungendered) language ID 0 to be Windows codepage 1252.  To override several
           encodings, specify the --encoding parameter multiple times.
     input_file
           The GFF file to convert.
     [output_file]
           The XML file will be written there.  If no output file is specified, the XML data is written to
           stdout.  The encoding of the XML stream is always UTF-8.

EXAMPLES

     Convert the GFF file1.utc into an XML file:

           $ gff2xml file1.utc file2.xml

     Convert the GFF file1.utc into an XML file on stdout:

           $ gff2xml file1.utc

     Convert the GFF file1.utc, which uses Windows CP-1252 strings:

           $ gff2xml --cp1252 file1.utc file2.xml

     Convert the GFF file1.utc, which encodes language ID 0 in LocStrings as Windows CP-1250:
           $ gff2xml --encoding 0=cp1250 file1.utc file2.xml
