Arch Linux

What do you mean, this script is part of p7zip or mc package?

This script is a pert of p7zip.
See contrib/VirtualFileSystemForMidnightCommander subdirectory in p7zip source tree.

Then adding p7zip support to mc will require makedepends=('p7zip') in mc's PKGBUILD, which is not very good, IMHO.

I think what is better to add this script to p7zip package.
Simply copy contents of contrib/VirtualFileSystemForMidnightCommander subdirectory as /usr/share/p7zip/* in p7zip package tree.
And anybody who want to use Midnight Commander together p7zip will configure it by hands.

Please test p7zip 4.57. It includes the file and some instructions.

p7zip-4.57-1 has wrong description as well as missing some files:
as it says:
:: In order to use p7zip with mc:
:: Add u7z to /usr/share/mc/extfs/extfs.ini
:: and add the following to /usr/share/mv/mc.ext:
:: regex/\.(7z|7Z)$
:: View=%view{ascii} 7za l -0.406997
:: Open=d 0xbfda0c3c#u7z

first: u7z does not exist at all:
10:09:04 papio@baboon:/home/tmp$ pacman -Ql p7zip
p7zip /usr/bin/7z
p7zip /usr/bin/7za
p7zip /usr/bin/7zr
p7zip /usr/lib/p7zip/7z
p7zip /usr/lib/p7zip/7z.so
p7zip /usr/lib/p7zip/7zCon.sfx
p7zip /usr/lib/p7zip/7za
p7zip /usr/lib/p7zip/7zr
p7zip /usr/lib/p7zip/Codecs/Rar29.so
p7zip /usr/man/man1/7z.1.gz
p7zip /usr/man/man1/7za.1.gz
p7zip /usr/man/man1/7zr.1.gz
p7zip /usr/share/mc/extfs/u7z
10:15:07 papio@baboon:/home/tmp$

second: /usr/share/mv/mc.ext does not exist at all, shoud be: /usr/share/mc/mc.ext ?

third: even adding this code to proper files (7z instead of u7z) it does not work with mc 4.6.1-4

ups, /usr/share/mc/extfs/u7z exists but still not working when added to /usr/share/mc/extfs/extfs.ini and to /usr/share/mc/mc.ext

Those are the instructions from the readme file. I don't use mc, so I don't know where to begin looking. Any help tracking this down would be great.

Besides editing /usr/share/mc/extfs/extfs.ini and /usr/share/mc/mc.ext (or ~/.mc/bindings) the permissions of /usr/share/mc/extfs/u7z have to be changed: it should be 755 instead of 644.

It still has issues though (directories are being show double and extracting is very slow) but that could be a local problem.

Assigned to Eric as well for consideration about implementing this, or not, before new mc hits extra

There is an error in the message pzip (p7zip-4.58-1) gives when installing/upgrading with pacman:

(complete original message)

This message is fixed in p7zip 4.58-2.

Was the message the only problem with the previous package?

u7z is part of p7zip package already.
