Hello g00r00!

ARJ and 7-ZIP revisited. :)

I performed an strace and noticed that Mystic appears to add "/dev/null 2>&1" to the end of the View Cmd command line. This seems to break things. But on Linux, it is possible to perform the following work-around:

     Active ³ Yes
  Extension ³ ARJ
         OS ³ Linux
Description ³ ARJ32 ARJ Utilities (CUSTOM)
   Pack Cmd ³ arj a -e -i -y "%1" "%2"
 Unpack Cmd ³ arj e -e -i -y -w"%3" "%1" "%2"
   View Cmd ³ arj l -i -y "%1" >> "%3%2" 2> /dev/null; exit $? >>

This will preserve the exit status of arj and tame the added /dev/null 2>&1
stuff.

The -i will remove any progress indicator from the output. Unsure if that one actually shows during viewing, as I haven't checked the source code, but it won't hurt, and it is at least good for packing/unpacking, I presume.

Also note that there should be no space between -w and "%3"; it appears to be the same thing for other platforms. Otherwise ARJ might complain and interpret the work directory as an archive file name.

And something similar for 7-ZIP:

       Active ³ Yes
    Extension ³ 7Z
           OS ³ Linux
  Description ³ 7-ZIP (CUSTOM)
     Pack Cmd ³ 7z a -y "%1" "%2"
   Unpack Cmd ³ 7z e -y -o"%3" "%1" "%2"
     View Cmd ³ 7z l -ba -y "%1" >> "%3%2" 2> /dev/null; exit $? >>

D.S.

All comments and thoughts welcome. :)

Best regards
Bj”rn
