Reminder: since UExtract supports lots of (un)archiving/(un)compressing/(en|de)crypting tools, most of which isn't available in practically any distro (or even in their repos, for that matter) OOTB, don't forget about a help file that comes with UExtract - /usr/local/apps/UExtract/help/LINKS.txt.
It contains links to sites from which you can obtain all the backends (source codes in most cases) used by UExtract.

Greetings!

Thanks SFR! If you don't already, perhaps you could output the same reminder with uextract -h / --help. I know it doesn't help in the GUI case, but at least the command line is covered. Just a thought.

Hey Step

If you decided to create a desktop shortcut during installation, you can right-click it (alternatively /usr/local/apps/UExtract AppDir itself) and you'll get that option (see screenshots).

Thank you L18L, I re-uploaded the .pet with your .mo file included.
Also fixed a small bug that prevented TEXTDOMAINDIR variable to be set properly.

Greetings!

I had to fix it also to test my translation. Wink
I was sure you find it, too. Cool
Translation worked OOTB.

(Maybe I should re-code momanager to use non-default TEXTDOMAINDIRs)

My first attempt to use uextract left me a bit puzzled Crying or Very sad

I tried to unpack /mnt/sda2/backup.img.gz, a 6BG image file created by Pudd.
I used the command
Code:
/mnt/home/apps/uextract /mnt/sda2/backup.img.gz

expecting that the resulting output file would be created in /mnt/sda2, the only partition large enough to accomodate a 10GB file. Apparently uextract tries to extract to a different location, but where? I receive an error "gzip: stdout: No space left on device", but which device? Also the following "Extraction failed!" doesn't really help. It would be nice if the console output could indicate the target path and it would be perfect (at least for me) if uextract would default output to the same directory as the input.

I finally succeded with the command
Code:
/mnt/home/apps/uextract -o mnt/sda2 /mnt/sda2/backup.img.gz

but still I don't find this intuitive.

Hey Mochi

If '-o' wasn't specified, UExtract sets output directory to current working dir (CUSTOMDIR="$(pwd)").
I can't recall exactly why I've chosen this way, but it was a concious choice and it's been unchanged since the initial release.
Anyway, I have to rethink your suggestion (and its possible good/bad implications).

Thanks for the feedback!
___________

Version 3.20:

- I came across an ISO image that can be mounted, as usual, but the contents of a mountpoint cannot be accessed ("permission denied", yes, for root!), unless 'norock' options was specified during mounting, so I added a workaround for this case
- can extract 'Unity-editor' installer
- added warning that some actions require root privileges (shows only if UExtract was launched by regular user)
- fixed missing 'gettext' in one spot
- minor rearrangements/optimizations

New formats/extensions:
  • .bzip (same as .bz)
  • .bzip2 (same as .bz2)
  • .cpio.bzip (same as .cpio.bz)
  • .cpio.bzip2 (same as .cpio.bz2)
  • .cpio.gzip (same as .cpio.gz)
  • .cxarchive (CrossOver Bottle Archive) [req. tar+gz]
  • .fp8 (FP8 (= Fast PAQ8) Compressed File) [req. fp8]
  • .jsonlz4 (Compressed Firefox Bookmarks Backup File) [req. lz4jsoncat]
  • .tar.bzip (same as .tar.bz)
  • .tar.bzip2 (same as .tar.bz2)

First post updated!

Greetings!

...and this is exactly the problem. For users of the ROX right-click app CUSTOMDIR (initially CURRENTDIR) is set in AppRun (CURRENTDIR="${IFILES[0]%/*}/" ). It does what I want it to do for the command line script uextract: it determines the (default) output dir from the path of the input archive. The problem is that AppRun doesn't export CUSTOMDIR to uextract. If it would be exported you could check in uextract if CUSTOMDIR has been set and cd to it. However if someone like me uses uextract from the command line, CUSTOMDIR would be empty and the script would have to do what AppRun did for ROX users: Peel off the path from the archive file and assign it to CUSTOMDIR.

Even if you decide to stick to your present code I still would recommend to make the target clear in the console output. Presently the output indicates the full path of the source file at least 2 times, but the path of the target directory not even once.

But never mind, I can manage Wink It's already a terrific piece of software. Thanks for that!

Hi SFR, is it worth bundling Barry's 7zip into UExtract?
http://barryk.org/blog/?viewDetailed=02319
I came across a .7z file and clicked on it (nothing happened) right clicked for UExtract and it had a go, but was unsuccessful.
So I installed Barry's http://distro.ibiblio.org/quirky/pet_packages-common/p7zip-9.20.1-i486-w5.pet and then UExtract did the business with all the notifications dialog ending with All OK.
Just thought it would be good, because UExtract and Packit seem to be the defacto no nonsense tools for Puppy in that department.

EDIT: Just realised I am using an older Pup and possibly newer pups have 7zip built in possibly, so maybe not a good idea after all.

To MochiMoppelel's comment below.
I am so used to double clicking into the directory, it doesn't bother me.

What bothers me more is the removal of the root /downloads folder in the new puppies, that's my temp folder! I always have to put that back in. One of many "improvements"?

I tested as a ROX application and I had no success to set a target directory from the xdialog selection box. I did as I'm told in the header text, I "selected" my output directory '/opt', then pushed OK. Files ended up in / Crying or Very sad I know that I can doubleclick into the target, but that's not the same as "selecting" and is not how the dialog is supposed to work.

As you can see in the right screenshot (taken from the xdialog manual), the dselect box should show an edit field at the bottom with the selected directory. This is what xdialog is supposed to return and this is also how the fselect box works. The dselect box "lost" its edit field and seems to be broken. Only for me? Using slacko 5.6.

Just note that if you do:
Code:
uextract /path/to/symlink_to_file_in_another_location

the file will be extracted in that another location, not where symlink is, because UExtract always operates on full, real paths to files.

RE: Xdialog
Well, it still shows the current selection ("Selection: /") at the very bottom of the window.
Also, as you can see, fselect, too, doesn't show currently highlighted folder as "selection" nor put it into edit field, which gets filled only with a filename selected in right pane.
I suspect it just might have changed at some point and IMHO now it's more logical and consistent.
___________

@Smithy: UExtract is a wrapper script for many external tools and 7z is just one them, so bundling 7z only would be unfair to the rest. Wink
Well, it crossed my mind to bundle UExtract along with _all_ tools that it supports, but it would be an awful mix of binaries with different/incompatibile licences, e.g. poweriso is free, but proprietary as well as unace, which comes with the following licence:
Quote:
Linux unace is provided free, "as-is". You may freely copy the program.
Distribution is permitted within this original package only.

Anyway, you can always copy p7zip (and whatever tools you might need) to usr/local/apps/UExtract/resources in unpacked UExtract package and create PET/SFS for your own use.
In fact, I keep (I need to, in order to develop this app) all the missing binaries there (see screenshot).

Btw, in case of p7zip you need to:
1. Copy /usr/local/lib/p7zip/ (or wherever the p7zip directory is) to 'resources' dir.
2. Create the following wrapper (and name it just 7z), also in 'resources' dir:
Code:
#!/bin/sh
MYPATH="$(dirname "$(readlink -f "$0")")"
"${MYPATH}/p7zip/7z" "$@"
