Opening .PAK and .ARC archives with Midnight Commander

[Trux]

1) Midnight Commander doesn't open .ARC archives.
After installing arc package, I can extract files from .ARC archive with Midnight Commander.
Could you please add a package dependency between mc and arc packages ?

2) Midnight Commander doesn't open .PAK archives.
After installing unar (not unrar) package, I can extract files from .PAK archive with the unar command but not with Midnight Commander.

Could you please add in Midnight Commander a call to unar command and a package dependency between mc and unar packages ?

Replying to Trux:

1) Midnight Commander doesn't open .ARC archives.
After installing arc package, I can extract files from .ARC archive with Midnight Commander.
Could you please add a package dependency between mc and arc packages ?

Such dependencies are not applicable in vanilla MC.
Please ask MC maintainer to add this dependency to MC package (rpm? deb? other?) in you distro.

2) Midnight Commander doesn't open .PAK archives.
After installing unar (not unrar) package, I can extract files from .PAK archive with the unar command but not with Midnight Commander.

Could you please add in Midnight Commander a call to unar command and a package dependency between mc and unar packages ?

Nobody created such extfs plugin yet. Patches are welcome!

Branch: 4130_unar
changeset:108e872cc5ee18f95a34d6f39f80c650040e503a

[Trux]

Thank you very much for the patch. How can I test it ? I must wait a new version in Linux Mint Cinnamon ?

[andrew_b]

The best way is build 4130_unar branch from source, test it and report found errors before merging branch into master.

Or wait for merge this branch into master, install suitable nightly build and then report errors in master.

[andrew_b]

Merged to master: [a2bccac622b4cb1a028cce31de1a686a2ca8c79d].

I tested with mc 4.8.30. I installed unar 1.10.1 and arc packages. I can browse EGACHESS.ARC​ file with mc but not MM34.PAK​.

[andrew_b]

$ ar tv MM34.PAK 
ar: MM34.PAK: file format not recognized

Can you download mc.ext.ini.in from here:

​https://github.com/MidnightCommander/mc/blob/master/misc/mc.ext.ini.in

... replace @EXTHELPERSDIR@ with the correct path, and use this instead of the shipped mc.ext.ini?

If my case with this file if I try to browse PAK, it says that I'm missing lsar, but I would assume that browsing would work, if I install it.

What message do you get, if you can't browse it? None at all, just Enter does nothing?

[Trux]

I'm using lsar installed with unar:

I replaced my /etc/mc/mc.ext.ini file with yours and replaced into it @EXTHELPERSDIR@ by /usr/lib/mc/ext.d. Then I can open MM34.PAK without any error message, it works fine.

[zaytsev]

Alright thanks for the confirmation, so it's fixed with #4502 and will be released with the next version. Until then you have a workaround.

[Trux]

Thank you very much.
