Package request: unblob

[vlaci]

Project description

I am a maintainer of unblob, an accurate, fast, and easy-to-use extraction suite. It parses unknown binary blobs for more than 30 different archive, compression, and file-system formats, extracts their content recursively, and carves out unknown chunks that have not been accounted for.

I'd like to add this package to nixpkgs. We already set-up a flake for this package that can build it with all of its dependencies. These dependencies that need to be added as well:

• sasquatch*: squashfs-tools with support for non-standard image formats
  There is already a derivation in nixpkgs from a fork of its original repository courtesy of @cole-h. Differences from upstream include:

  • We unrolled the original patch to git commits over the upstream sources to ease maintenance
  • Building big-endian versions of the binary in or flake
  • Added Darwin support

  sasquatch: 4.4 -> 4.5.1-1 #219169

• pyperscan*: a hyperscan binding for Python, which supports vectorscan: an alternative binding for aarch64 support
  python310Packages.pyperscan: init at 0.2.2 #232314

• vectorscan : as a dependency for pyperscan
  python310Packages.pyperscan: init at 0.2.2 #232314

• arpy: an ar format parser Python library
  python3Packages.arpy: init at 2.3.0 #217903

• jefferson*: a JFFS2 filesystem extraction tool written in Python
  jefferson: init at 0.4.2 #217843

• cstruct: a Python library to parse data using C style struct definitions. (Dependency of jefferson)
  jefferson: init at 0.4.2 #217843

• ubi-reader: a tool for reading UBI/UBIFS images written in Python
  ubi_reader: init at 0.8.5 #217917

I am a maintainer of packages marked by *, but I am willing to package and submit PRs for all of the above dependencies as well.

The one outstanding question is how to handle sasquatch. Can we unify our efforts, or shall we have different forks?

I had a jefferson package definition laying around, so I created a PR #217843

[thornycrackers]

arpy looked simple so I took a stab at it

@vlaci, I believe pyperscan and vectorscan can be checked in the main comment of this issue, I believe all that's left for unblob to be packaged is sasquatch that isn't merged yet.

[qkaiser]

We need to find a way to move forward with the sasquatch PR, see #219169 (comment)

[AkechiShiro]

@qkaiser the PR is merged

[AkechiShiro]

@vlaci Is there anything else missing to package unblob now that sasquatch is merged ?
