novadrop-dc

novadrop-dc <command> <arguments...> [options...]

The novadrop-dc tool allows manipulation of TERA's data center files. It supports the following tasks:

Extraction of data center files to XML data sheets with corresponding XSD schemas.
Reasonably accurate inference of XSD schemas from a packed data center file.
Validation of data sheets against schemas, preventing many mistakes when authoring data sheets.
Packing of data sheets in accordance with type and key information in schemas to a fresh data center file usable by the client.
Format integrity verification of data center files, optionally with strict compliance checks.
Support for various iterations of the data center format throughout the game's history.

In general, novadrop-dc is quite fast: It exploits as many cores as are available for parallel extraction, validation, and packing. On a modern system, unpacking an official data center file takes around 15 seconds, while packing the resulting data sheets takes around 25 seconds.

novadrop-dc pack

novadrop-dc pack <input> <output> [options...]

Packs the data sheets in a directory to a data center file. If validation of the data sheets fails during packing, a list of problems will be printed and the exit code will be non-zero.

The input argument specifies a directory containing data sheets and schemas. The output argument specifies the path of the resulting data center file.

Option

Description

novadrop-dc repack

novadrop-dc repack <input> <output> [options...]

Repacks a data center file without unpacking to disk. This command is primarily useful for development of novadrop-dc.

The input argument specifies the input data center file. The output argument specifies the path of the resulting data center file.

novadrop-dc schema

novadrop-dc schema <input> <output> [options...]

Performs best-effort inference of the schemas for the data tree in a data center file. This may be useful when working with older data centers for which Novadrop's included schemas are not correct.

Please note that, regardless of whether the Conservative or Aggressive inference strategy is used, the generated schemas will require a human touch after they have been generated. Among other things, this command cannot tell whether a given path in the tree with repeated node names represents a truly recursive structure.

The input argument specifies the input data center file. The output argument specifies the path of the directory to write inferred schemas to.

novadrop-dc unpack

novadrop-dc unpack <input> <output> [options...]

Unpacks the data tree in a data center file to a series of data sheets and schemas in a directory. This command is primarily intended for unpacking official data center files into a form that is easily maintainable by humans.

The input argument specifies the input data center file. The output argument specifies the path of the directory to extract data sheets and schemas to.

novadrop-dc validate

novadrop-dc validate <input>

Validates the data sheets in a directory against their schemas. If validation of the data sheets fails, a list of problems will be printed and the exit code will be non-zero.

The input argument specifies a directory containing data sheets and schemas.

novadrop-dc verify

novadrop-dc verify <input> [options...]

Verifies the format integrity of a data center file. This means traversing the entire data tree, reading all nodes and attributes, and ensuring that no errors occur.

The input argument specifies the input data center file.
