This code has been transpiled from ipfs-unixfs-exporter and has minimal changes.
DAG-PB, Raw, DAG-CBOR, and Identity codecs are supported.
` >>> from unix_fs_exporter import UnixFSFile, UnixFSDirectory, RawNode, ObjectNode, IdentityNode`
Given a block store and a root cid, decode the underlying data.
` >>> from unix_fs_exporter import RawNode, export, BlockStore >>> from multiformats import CID, multicodec, multihash ... >>> class SomeBlockStore(BlockStore): ... def __init__(self): ... self.mapping = dict() ... ... async def get_block(self, cid): ... return self.mapping[cid.digest] ... >>> data = b'some data' >>> mh = multihash.get('sha2-256').digest(data) >>> cid = CID('base32', 1, 'raw', mh) >>> block_store = SomeBlockStore() >>> block_store.mapping[cid.digest] = data ... >>> async def test(): ... result = await export(cid, block_store) ... assert isinstance(result, RawNode) ... ... async for chunk in result.content: ... print(chunk) ... >>> asyncio.run(test()) b'some data'`
Recursively iterate through a directory.
` >>> from unix_fs_exporter import recursive_export, UnixFSFile >>> # Creation of the blockstore is an exercise left to the reader >>> async def test(): ... entries = recursive_export('bafybeifpaez32hlrz5tmr7scndxtjgw3auuloyuyxblynqmjw5saapewmu', block_store) ... async for entry in entries: ... assert isinstance(entry, UnixFSFile) ... async for chunk in entry.content: ... assert isinstance(chunk, bytes) >>> asyncio.run(test())`
