Those are Midnight Commander extfs plugins for handling several archive types mostly known from AmigaOS - like lha, lzx and disk images like adf and dms.

Installation

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

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

• 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.d/

• 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.d/

• 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 unadf utility from ADFlib repository, with included that commit in particular, which introduced separation between filename and comment attribute on Amiga Fast File System.

If it turns out that your distribution doesn't provide proper version of ADFlib, there will be a need for building it by hand.

It may be done by using following steps:

1. Grab the sources and patches from Debian repository.

2. Extract unadf_0.7.11a-3.debian.tar.gz and unadf_0.7.11a.orig.tar.gz into some temporary 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

3. Apply Debian patches:

   $ for i in `cat ../debian/patches/series`; do
   > patch -Np1 < "../debian/patches/${i}"
   > done

4. Apply the patch from extras directory:

   $ patch -Np1 < [path_to_this_repo]/extras/unadf_separate_comment.patch
   $ make
   $ cp Demo/unadf [destination_path]

5. Place unadf binary under directory reachable by $PATH.

For optional dms support, xdms utility is needed.

Installation

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

• 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://
