RAR not supported on Fedora with

[etiennemlb]

In #117 I erroneously mentioned that XArchiver rejected opening a RAR archive with its extension renamed to .cbr (a EBook format).

It turns out that the main issue seems to come from Fedora 38's p7zip-plugins package which provides a 7z binary not supporting RAR anymore. As per man 7z(1), RAR (it was removed due a non-free license).

I am using 7z version 16.02 and here are some strace logs.

ERROR:
Unsupported archive type

Which tools, still available on Fedora, can be used to produce and ingest RAR archives and is it already supported by XArchiver.

[ib]

I don't know about Fedora, but there are Linux console versions (binaries and source) available directly from 7-zip.org and the UnRAR source from rarlab.com.

p7zip is IMO outdated and obsolete.

BTW, the missing MIME type support to be able to open it from a file manager will be added as soon as I find time.

[etiennemlb]

@ib I may have missed something, but AFAIK, XArchiver does deduce correctly that the .cbr file is a RAR file.

[etiennemlb]

There, it calls 7z as it should, assuming it supports RAR

[ib]

Yes, but you can't open .cbr with your file manager, but you can open .cbz this way.

Extension cbr and all other comic book file extensions are now associated with xarchiver (in master).
