squashfs

A PURE Go library to read squashfs. There is currently no plans to add archive creation support as it will almost always be better to just call mksquashfs. I could see some possible use cases, but probably won't spend time on it unless it's requested (open a discussion fi you want this feature).

Currently has support for reading squashfs files and extracting files and folders.

Special thanks to https://dr-emann.github.io/squashfs/ for some VERY important information in an easy to understand format. Thanks also to distri's squashfs library as I referenced it to figure some things out (and double check others).

TODO

Limitations

• No Xattr parsing. This is simply because I haven't done any research on it and how to apply these in a pure go way.

Performance

Testing on a zstd compressed file, my library is anywhere from 5x ~ 7x slower then unsquashfs
