tar mode and package.el can't support bsdtar in mac OSX

tar mode and package.el can't support bsdtar in mac OSX

[陈云星]

i create a tarball with bsdtar( the default tar tool in Mac osx) then open it with emacs tar-mode.

but it can't be opened.

and i also found the package.el only support gnutar format of tar , not the bsdtar.

can any method to  solve these problem ?

This should be sent to emacs-devel@gnu.org, as they seem to be bugs or
missing features.

Please also give details about how you used bsdtar to create a tarball
that Emacs couldn't open.

On Mac OS X 10.6.8, Snow Leopard, I cannot reproduce this. The bsdtar archive I created can be opened with /usr/bin/emacs -Q. What's puzzling is that bsdtar includes the metadata resource forks of regular files into the archive, as in:

	 -rw-r--r--     501/80          452 ./._vishnusmriti.txt
	 -rw-r--r--     501/80       402641 vishnusmriti.txt
	 -rwxr-xr-x     501/80          323 emacs.sh
	 -rw-r--r--     501/80        10913 dot-emacs
	 -rw-r--r--     501/80          478 ./._test-vertical.tex
	 -rw-r--r--     501/80          268 test-vertical.tex
	 -rw-r--r--     501/80          477 ./._ThreeKingdomsCh1.tex.zip
	 -rw-r--r--     501/80         9639 ThreeKingdomsCh1.tex.zip

What I cannot open successfully is the ZIP archive inside the bsdtar archive.

For help give more details! How did you create the bsdtar archive? What was the command line? How did you launch GNU Emacs? Did you try it with -Q, i.e., without any customisation? What is your Mac OS X version? Which version of GNU Emacs are you using?

the ._xxx file was generated by Mac sox when creating tar ball,
you can disable this by set environment variable COPYFILE_DISABLE=1:

COPYFILE_DISABLE=1 gnutar cf dir.tar dir
