# ckanext-unfold
Enhance your CKAN experience with our extension that enables seamless previews of various archive formats, ensuring easy access and efficient data management.
## What are the dependencies?
Working with different archive formats requires different tools:
### RAR, CBR
It depends on `unrar` command-line utility to do the actual decompression. Note that by default it expect it to be in `PATH`.
If unrar launching fails, you need to fix this.
Alternatively, `rarfile` can also use either [unar](https://theunarchiver.com/command-line) from [TheUnarchiver](https://theunarchiver.com/) or
[bsdtar](https://github.com/libarchive/libarchive/wiki/ManPageBsdtar1) from [libarchive](https://www.libarchive.org/) as
decompression backend. From those unar is preferred as bsdtar has very limited support for RAR archives.
It depends on [cryptography](https://pypi.org/project/cryptography/) or [PyCryptodome](https://pypi.org/project/pycryptodome/)
modules to process archives with password-protected headers.
### 7Z
We are using [`py7zr`](https://py7zr.readthedocs.io/) library.
The py7zr depends on several external libraries. You should install these libraries with py7zr.
There are `PyCryptodome`, `PyZstd`, `PyPPMd`, `bcj-cffi`, `texttable`, and `multivolumefile`.
These packages are automatically installed when installing with pip command.
For extra information, please visit the [official documentation](https://py7zr.readthedocs.io/en/latest/user_guide.html#dependencies),
especially the dependencies section.
### ZIP, ZIPX, JAR
We are using built-in library [`zipfile`](https://docs.python.org/3/library/zipfile.html). Please consider referring to the official documentation for more information.
### TAR, TAR.XZ, TAR.GZ, TAR.BZ2
We are using built-in library [`tarfile`](https://docs.python.org/3/library/tarfile.html). Please consider referring to the official documentation for more information.
### RPM
We are using [`rpmfile`](https://github.com/srossross/rpmfile) library.
If you want to use rpmfile with zstd compressed rpms, you'll need to install the [`zstandard`](https://pypi.org/project/zstandard/) module.
