arsd.archive

Provides LZMA (aka .xz), gzip (.gz) and .tar file read-only support. Combine to read .tar.xz and .tar.gz files, or use in conjunction with other libraries to read other kinds of files.

Also has a custom archive called arcz read and write support. It is designed to efficiently pack and randomly access large numbers of similar files. Unlike .zip files, it will do cross-file compression (meaning it can significantly shrink archives with several small but similar files), and unlike tar.gz files, it supports random access without decompressing the whole archive to get an individual file. It is designed for large numbers of small, similar files.

Members

Classes

ArzCreator class ArzCreator: this class can be used to create archive file.

Enums

SEEK_SET (from core.stdc.stdio) anonymousenum SEEK_SET via public import core.stdc.stdio : SEEK_SET, SEEK_CUR, SEEK_END;
TarFileType enum TarFileType: There's other types but this is all I care about. You can still detect the char by ((cast(char) type) + '0')

Functions

decompressGzip void decompressGzip(void delegate(in ubyte[] chunk) chunkReceiver, ubyte[] delegate(ubyte[] buffer) bufferFiller, ubyte[] chunkBuffer, ubyte[] inputBuffer, bool allowPartialChunks): decompressLzma lzma (.xz file) decoder/decompressor that works by passed functions. Can be used as a higher-level alternative to XzDecoder. decompressGzip is gzip (.gz file) decoder/decompresser) that works by passed functions. Can be used as an alternative to std.zip, while using the same underlying zlib library.
decompressLzma void decompressLzma(void delegate(in ubyte[] chunk) chunkReceiver, ubyte[] delegate(ubyte[] buffer) bufferFiller, ubyte[] chunkBuffer, ubyte[] inputBuffer, bool allowPartialChunks): decompressLzma lzma (.xz file) decoder/decompressor that works by passed functions. Can be used as a higher-level alternative to XzDecoder. decompressGzip is gzip (.gz file) decoder/decompresser) that works by passed functions. Can be used as an alternative to std.zip, while using the same underlying zlib library.
processTar bool processTar(TarFileHeader* header, long* bytesRemainingOnCurrentFile, const(ubyte)[] dataBuffer, void delegate(TarFileHeader* header, bool isNewFile, bool fileFinished, const(ubyte)[] data) handleData): Low level tar file processor. You must pass it a TarFileHeader buffer as well as a size_t for context. Both must be initialized to all zeroes on first call, then not modified in between calls.

Imports

SEEK_CUR (from core.stdc.stdio) public import core.stdc.stdio : SEEK_SET, SEEK_CUR, SEEK_END;
SEEK_END (from core.stdc.stdio) public import core.stdc.stdio : SEEK_SET, SEEK_CUR, SEEK_END;

Structs

AZFile struct AZFile: Opened file.
ArzArchive struct ArzArchive: ARZ archive accessor. Use this to open ARZ archives, and open packed files from ARZ archives.
TarFileHeader struct TarFileHeader: A header of a file in the archive. This represents the binary format of the header block.
XzDecoder struct XzDecoder: A simple .xz file decoder.
