Hmm, yes, indeed, seems to be right... The emulation of tar in tar-mode.el
leads me to the (wrong) assumption that this is also possible for *.gz files....
Appaerently a wrong assumption ;-)

I know tar-mode and it displays a dired-like listing of the contents.
So the user can mark entries and extrakt them to a buffer...
What i want is the following:
Is it possible with tar-mode (or other already existing elisp-code), to
extract the full contents of a tar-file to a certain directory (or at least to
default-directory)?
Ciao,
Klaus

There is an easier work-around in Emacs shell:
cd <some directory>
tar xf <some tar file>

I don't believe this could work. GNU Emacs needs external programmes
like bzip2, gunzip, etc. to unpack the contents from a compressed file.
You can proof that yourself: rename the decompressors and try to open a
compressed tar file!

But doesn't emacs tar-mode just use tar 'under the hood'?
It may be possible to work out how to extract files from a tar archive
reasonably easily, but the unzipping/decompressing is going to be
difficult/impossible. Also, keep in mind that as GNU tar also supports
bzip2 compression, we are likely to see archive.tar.bz2 as well as
archive.tar.gz more often.
Why the need not to use the correct tools? Is it because of platforms
which may not have tar or tar and gunzip equivelants and if so, what
platforms?

No, untarring is done via elisp - see tar-mode.el

yes, good point!

I had the wish to do it completely from within Emacs for my package so the
user has no need for installing stuff like tar or gzip (especially in
Windows-envs) - but the latter one is impossible, i see it now...

No. AFAIK Jamie Zawinsky wrote a native 'interpreter' for Tape ARchive
files. It scans the structures, sees when a file or directory starts
and ends, sees times and permissions ...
There is no such mechanism to un-compress (LHarc, arc, zip, gzip, UNIX
compress, bzip2, Windows RAR and CABinet and PKzip, Mac OS Stuff and
much older stuff, ...)

Or from dired, hit !
,----[ C-h f dired-do-shell-command RET ]
| dired-do-shell-command is an interactive compiled Lisp function in `dired-aux'.
| (dired-do-shell-command COMMAND &optional ARG FILE-LIST)
|
| Run a shell command COMMAND on the marked files.
| If no files are marked or a specific numeric prefix arg is given,
| the next ARG files are used. Just C-u means the current file.
| The prompt mentions the file(s) or the marker, as appropriate.
|
| If there is output, it goes to a separate buffer.
|
| Normally the command is run on each file individually.
| However, if there is a `*' in the command then it is run
| just once with the entire file list substituted there.
|
| If there is no `*', but a `?' in the command then it is still run
| on each file individually but with the filename substituted there
| instead of at the end of the command.
|
| No automatic redisplay of dired buffers is attempted, as there's no
| telling what files the command may have changed. Type
| M-x dired-do-redisplay to redisplay the marked files.
|
| The shell command has the top level directory as working directory, so
| output files usually are created there instead of in a subdir.
|
| In a noninteractive call (from Lisp code), you must specify
| the list of file names explicitly with the FILE-LIST argument.

Have you seen emacs-goodies-el ?
there you have M-x browse-huge-tar-file, and it can work on a gziped one.

The gunzipping needs to be done by an external program, but the untarring
can be performed by Emacs itself. See install.el for an example of how you
can do that using tar-untar-buffer. It's pretty untested code, tho.
