mcwutil-1.3 Release Notes

This release adds two new commands:

• coord-calc accepts a coordinate pair and outputs some useful geometric information.
• nbt-block-substitute remaps block IDs in the terrain in an Anvil NBT while handling block IDs up to 4095 properly.

mcwutil-1.2 Release Notes

This release adds the zlib-check command which decompresses a ZLib file without saving the output. Minor bug fixes are also included.

mcwutil-1.1 Release Notes

This release adds support for the new Anvil format by processing integer array tags in NBT files.

mcwutil-1.0 Release Notes

The following tools are included in this release:

• region-unpack - unpacks the chunks from a region file
• region-pack - packs chunks into a region file
• zlib-decompress - decompresses a ZLIB-format file
• zlib-compress - compresses a ZLIB-format file
• nbt-to-xml - converts an NBT file to an equivalent XML file
• nbt-from-xml - converts an NBT-equivalent XML file to an NBT file
• nbt-patch-barray - replaces specific byte values in NBT byte arrays with other values

To successfully compile the code, you will need the following packages installed:

• glibmm
• libxml++
• zlib

There are also example scripts in the scripts directory.

The roundtrip-test-regions script is written in Bash and needs only md5sum to work. This script can be used as a self-test of the NBT-to-XML-to-NBT conversion routines.

The other scripts are written in Python and also require xmlstarlet. These scripts are probably more useful as examples of how mcwutil can be used than for direct application.
