xwformats 0.9.0.23

Convenience wrapper for exonware-xwformats - provides 'import xwformats' alias

xwformats

Many serialization formats, one package. Schema (Protobuf, Parquet, Thrift, …), scientific (HDF5, Feather, Zarr, …), database (LMDB, LevelDB, …), plus binary and text. Same converter style as xwsystem; formats register on import. Pick lite, lazy, full, or dev extras to match how you deploy.

Install

Install	What you get	When to use
pip install exonware-xwformats	Lite - exonware-xwsystem + exonware-xwlazy	Small install; add formats via [full] or lazy hooks.
pip install exonware-xwformats[lazy]	Lazy - xwsystem[lazy] + lazy extras	Matches lazy-optional stack in docs.
pip install exonware-xwformats[full]	Full - common format deps installed up front	Production or CI; on Windows, LevelDB/RocksDB wheels may be missing (see docs/REF_54_BENCH.md).
pip install exonware-xwformats[dev]	Dev - pytest, black, mypy, …	Contributors

Base install always pulls exonware-xwsystem and exonware-xwlazy. [lazy], [dev], and [full] are extras.

Quick start

from exonware.xwformats import XWFormats

xf = XWFormats()
print(xf.list_formats())                       # All registered formats
data = xf.convert(json_bytes, "json", "yaml")  # Bidirectional conversion
ser = xf.get_serializer("parquet")
ser.encode(value)
ser.decode(data)

Importing xwformats registers its formats with xwsystem; use xwsystem's codec/facade for detection by file extension. See REF_14_DX and REF_15_API.

What you get

Area	What's in it
Schema	Protobuf, Parquet, Thrift, ORC, Cap'n Proto, FlatBuffers, Arrow. Avro is optional (may be off default import on some platforms - see __init__.py and docs/_archive/KNOWN_ISSUES.md).
Scientific	HDF5, Feather, Zarr, NetCDF, MAT.
Database	LMDB, LevelDB, RocksDB, GraphDB.
Binary / text	BSON, UBJSON; CSV, YAML, TOML, XML, RON.
Integration	Same converter/facade as xwsystem; codec registry updated on import.

Lite = few deps. Lazy = optional format wheels on first use. Full = common optionals pre-installed. Platform notes (e.g. RocksDB on Windows): docs/logs/setup/. Known issues: docs/_archive/KNOWN_ISSUES.md and REF_22_PROJECT.md.
