1 make use of modern tar options, like '--use-compress-program=prog'
2 cfg_use_tar_compress_option?
4 if making RPM, then upload SRPM as well!
6 improve messages printed from arepack. sometimes prints unnecessary messages like "data.tar.gz: extracted to `Unpack-2962/data'"
8 cat mode is not supported for lzop, because it won't write to standard out
9 unless we give it the -f option. Because of this we use lzop as if -c was
10 not supported. This should be fixed in the future.
12 --no-umask option from Reuben
14 aunpack -e is default - or perhaps with option to make it default?
18 unpack archive to a separate directory
19 for each unpacked file, check if it exists and is the same in the current directory.
20 if yes, remove that file in the current directory, and (optionally) from unpacked directory as well.
21 if no, remove that file from the unpacked directory
23 From Francois Marier <francois@debian.org>: check if pbzip2 is in the path and use it
25 rewrite atool implement extract_archive that is sensitive or not
27 add option to assume format with -F in some situations (like tar.gz)?
28 add option to always assume -e? and add some option for the reverse (-s, --single)
29 assume -e when passing a single directory as argument?
31 change back error messages to:
32 cannot foo `bar': No such file or directory
33 make function to format error message?
35 have autoconf generate files in debian subdir as well?
37 in readconfig, add datatype checking to options (bool/str/int/..)
39 add 'atest': test archive integrity
40 add compression level control arguments: store (0) or 1-9
41 make sure atool has non-zero rc when acat can't find a file (.arc files and possibly other)
43 improve error message when some program doesn't exist (now gets unnecessary lines)
45 arepack -F.tar.bz2 foo.tar.gz would only gunzip then bzip2. tar not involved!
52 does zip treat *?[]\ chars in filenames specially?
54 use "--" with gzip and others?
56 Reasons to rewrite in C:
57 - use manual ZIP code so that we can extract archive with '../foo' files too!
58 tar fails entirely when the archive contains '../xxx' members.
59 - the option --save-outdir in extract-to mode could be implemented
61 - multiple commands per action more easily (same with perl tho)
62 - always identify format using magic values, ignoring extension (fast!)
63 - i18n much easier (and faster)
66 implement list command for single compressed archives? only gzip supports -l
68 apack dummy.tar.gz /etc/hostname
71 Archive is now extracted with file as dummy/etc/hostname
72 Should it be dummy/hostname or etc-1/hostname instead?
75 add support for SEA arc.
76 add support for szip (hard because its interface is different from gzip)
77 make an ACE archive (using winace stuff), test ACE extraction!
78 add support for DEB files
79 list: dpkg-deb -c FILE.deb
80 extract: dpkg-deb -x FILE.deb $outdir/CONTENTS
81 dpkg-deb -e FILE.deb $outdir/DEBIAN
83 Implement 'use_jar_for_zip' - use jar for zip archives (fastjar) - test
84 Rename 'use_zip_for_jar' - use zip for jar archives - test
85 Enable add command for jar archives!
89 make a script to detect system settings and configure atool appropriately
90 Make it possible to send additional arguments to RAR etc. engine configurable via command line?
91 especially adiff diff -ruN (note the N) option

160 arepack -R -r extract and pack archives
166 -f -f (classify) like ls
167 -m[TYPE] from all archives, list only files matching (remaining args are matches)
169 prev: als -e *.tar now: als *.tar
170 prev: als foo.tar f* now: als foo.tar -m f*
173 -X DIR where to extract to (otherwise be smart)
174 -m[TYPE] from all archives, extract only files matching (remaining args are matches)
176 apack ARCHIVE FILE1..
177 -a add files if archive already exists (without -a, refuse to overwrite existing)
178 -e all arguments are files (or dirs) to compress individually
179 -F FORMAT force file format
181 -f allow overwriting of archives (clobber). NOTE: for safety, this implies

188 # This document shows how a future rules file format for atool could look. It

190 # possible this format will never become a reality due to its complexity.

194 # rules and configuration files are the same

292 better extraction semantics, cleaner code
294 * always use change to directory for extraction, never specify dir on cmd command-line?
295 use ../for instead of absolute dir
296 merges extract-to and extract
298 * core support for multiple commands per mode (think debian)
300 * better control of user arguments to external command (@args)
302 * better solution than multiarchivecmd - cleaned up
304 * more general commands:
307 * more general options
310 * stripext only based on format! (e.g. unpack gz then strip .gz, not .tar.gz)
312 want aunpack -e to be default!
