Those are Midnight Commander extfs plugins for handling several archive types.

Installation

See individual installation plugins below. Basically it comes down to:

• copying extfslib.py and plugin files to ~/.local/share/mc/extfs/

• installing binary handlers (lha, unlzx, xdms and unadf)

• adding an entry in ~/.config/mc/mc.ext:

  # arch
  regex/\.pattern$
       Open=%cd %p/handler_filename://

ULha

ULha is an extfs plugin which can be used with lha/lzh/lharc archives. Personally, I've use it almost exclusively for archives created long time ago on my Amiga. Both reading from and writing into archive was implemented.

Requirements

ULha requires free lha implementation to work.

Installation

• copy extfslib.py and ulha to ~/.local/share/mc/extfs/

• add or change entry for files handle in ~/.config/mc/mc.ext:

  # lha
  regex/\.[lL]([Hh][aA]|[Zz][hH])$
       Open=%cd %p/ulha://
       View=%view{ascii} lha l %f

ULzx

ULzx is an extfs plugin which can be used to browse and extract lzx archives, which are known almost exclusively from Amiga.

Due to limitations of unlzx tools, only reading is supported. Also be aware, that unlzx cannot extract files individually, so copying entire archive content is not recommended, since on every single file a full archive extract would be performed, which in the end would have impact on performance.

Requirements

ULzx requires unlzx tool.

Installation

• copy extfslib.py and ulzx to ~/.local/share/mc/extfs/

• add or change entry for files handle in ~/.config/mc/mc.ext:

  # lzx
  regex/\.[lL][zZ][xX]$
       Open=%cd %p/ulzx://
       View=%view{ascii} unlzx -v %f

UAdf

UAdf is an extfs plugin suitable for reading .adf, .adz and .dms Amiga floppy disk images. Due to limitations of the unadf, file access inside disk image is read only.

In case of corrupted or no-dos images, message will be shown.

Requirements

It requires the unadf utility. Unfortunately, the page containing original sources doesn't exists anymore. Luckily, there is a copy of the source (and useful patches) in Debian repository.

There should be one change made to the source of unadf, though. While using "-lr" switch, unadf by default also displays comments next to file name, separated by the comma. If comment or filename contains comma sign, there is no way to distinguish where filename ends and comment starts. In extras directory there is a patch for fixing this - no comments would be displayed by default.

First, grab the sources and Debian patches. Apply them. To do this manually, extract unadf_0.7.11a-3.debian.tar.gz and unadf_0.7.11a.orig.tar.gz into some temporary directory. Apply patches in order like in debian/patches/series file. Then apply patch from extras directory:

$ mkdir temp
$ cd temp
$ tar zxf ~/Downloads/unadf_0.7.11a-3.debian.tar.gz
$ tar zxf ~/Downloads/unadf_0.7.11a.orig.tar.gz
$ cd unadf-0.7.11a
$ for i in `cat ../debian/patches/series`; do
> patch -Np1 < "../debian/patches/${i}"
> done
$ patch -Np1 < [path_to_this_repo]/extras/unadf_separate_comment.patch
$ make
$ cp Demo/unadf [destination_path]

unadf binary should be placed in $PATH.

For optional dms support, xdms utility is needed.

Installation

• copy extfslib.py and uadf to ~/.local/share/mc/extfs/

• add or change entry for files handle in ~/.config/mc/mc.ext:

  # adf
  type/^Amiga\ .* disk
      Open=%cd %p/uadf://
      View=%view{ascii} unadf -lr %f
  
  # adz
  regex/\.([aA][dD][zZ])$
      Open=%cd %p/uadf://
  
  # dms
  regex/\.([dD][mM][sS])$
      Open=%cd %p/uadf://
