arsd.archive

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

anonymousenum LZMA_FINISH_ANY
Undocumented in source.
LZMA_STATUS_NOT_SPECIFIED
anonymousenum LZMA_STATUS_NOT_SPECIFIED

There's other types but this is all I care about. You can still detect the char by ((cast(char) type) + '0')

processTar
bool processTar(TarFileHeader* header, long* bytesRemainingOnCurrentFile, ubyte[] dataBuffer, void delegate(TarFileHeader* header, bool isNewFile, bool fileFinished, ubyte[] data) handleData)
