rbedrock 0.4.1

• Undefined behavior identified by the M1-San system was fixed.

rbedrock 0.4.0

Breaking Changes

• This release includes a new API for reading and writing from the world database. The new API is designed to better support pipes and use a common database connection across functions. Most functions associated with reading and writing values to a world database were impacted. Consider the process of getting a set of values from a common prefix.

  db <- bedrockdb(dbpath)
  # Previous API
  dat <- get_data(db, starts_with = prefix)
  # New API
  #   - automatically uses db
  #   - prefixes created with helper function
  dat <- get_data(starts_with(prefix))
  
  # Previous API
  put_data(db, dat)
  # New API
  put_data(dat)
  
  # Previous API
  put_values(db, names(dat), dat)
  # New API
  put_data(dat, names(dat))

• As part of the new API, the get_values(), set_values(), and related _values() functions were removed.

• The API for working NBT and rNBT values has been reimagined.

  • NBT lists are now treated as vectors where ever possible.
  • NBT longs are now stored as strings to protect against data loss.
  • NBT integers are now stored as doubles to protect against data loss.

• New get_blocks_* and put_blocks_* functions have replaced get_chunk_blocks_* and put_chunk_blocks_*. The new functions work per chunk and always return blocks as a 16 x 384 x 16 array, regardless of the dimension.

New Features

• New default_db() function to get/set a default db connection.
• New print() etc. commands for printing NBT using a tree structure.
• New with_db() and local_db() for temporarily changing the default db connection.

Miscellaneous Fixes and Features

• New pkgdown-based website for rbedrock.
• The requirements for a key to be interpreted as a chunk key has been relaxed. Now any raw key of length 9, 10, 13, or 14 will be considered a chunk key if it contains at least one non-printable character. Collisions between plain and chunk keys can still occur, but they are not likely in this scheme.
• New biome_name() function for converting from a numeric id to biome name.
• New read_rnbt_once() function to parse NBT data that is mixed in with non NBT data. It returns a single NBT value along with how may bytes the value was.
• New blocks_nbt() and blocks_str() functions to convert block data between NBT and string representations.
• spawning_area() no longer requires a chunk to be withing 96 blocks of a player.
• Vendored LevelDB library is now built with exceptions enabled to avoid libcxx including abort() calls if exceptions are not enabled.
• The following dependencies were removed stringr, dplyr, purrr, magrittr, reader, vctrs, tidyr, and fs.

RBedrock 0.3.3

• Fix notes identified by CRAN. (Unused calls to stderr and abort.)
• Update included leveldb library.

RBedrock 0.3.2

• Fixed errors in usage of Rf_error().
• Use R_len_t in more locations.

RBedrock 0.3.1

• Remove hardcoded C++17 requirement when calling CMake.

RBedrock 0.3.0

• Added support for reading and writing 1.18.30+ actor digests.
• Chunk data functions have been expanded.
• [Breaking Change] Biome functions now return CNC biomes data (CnC biome functions have been renamed.) Accessing legacy biome data can be done with legacy biome functions.
• [Breaking Change] Chunk data functions and files have been renamed to match internal Mojang names.
• [Breaking Change] Chunk data functions no longer default to reading all keys from db if no keys are present.
• [Breaking Change] Chunk tag key descriptions have been changed to better match internal Mojang descriptions.
• Maximum chunk key tag has been increased to 96.
• [Breaking Change] Change key format to require prefixes in front of every key. This allows rbedrock to support multiple key formats.
• Add nbt_raw_string to support reading and writing nbt_string data that contains embedded nulls.
• Change default parameters to bedrockdb to match Minecraft. This reduces the size of worlds modified by rbedrock.
• Generate random world seeds using 64-bits.
• [Fix] Generate default package options on loading rbedrock. This fixes users not being able to find the world directory on Window.
• Create 1.19+ worlds by default when using create_world()
• Add functions for reading and writing actors data for a chunk.
• Add utility functions for working with unique ids.

RBedrock 0.2.0

• Support subchunk version 9 introduced for Caves and Cliffs.
• Support Caves and Cliffs’ 3DMaps.
• Change tag format to @x:z:d:t:s. This change was made because subtags can now be negative.
• Add locate_blocks() function.
• Introduce intermediate rnbt (raw nbt) format.
• Introduce new NBT API based on S3 classes.
• Remove layer and simplify arguments to get_subchunk_layers_value() and friends.
• Improved ChunkVersion API
• Remove -Werror flag used by leveldb on some platforms
• Added 1.18 example world
• Add support for 1.18’s empty palettes.
• Rename chunk tag to match internal bedrock names.
• Add starts_with option to get_values(), and db$mget_prefix() and bedrock_leveldb_mget_prefix() function.
• Add get_subchunk_blocks_from_chunk() function to efficiently lead subchunks from a single chunk.
• Add utility functions for calculating spawning area and simulation area.

RBedrock 0.1.1

• Fixed errors identified by UBSAN and Valgrind
• Improved the detection of cmake binary.
• RBedrock can now be compiled on Solaris using GCC.
• RBedrock can now be compiled by CRAN’s MacOS builder.
• Updated README.md
