Crover - generate OS version numbers for Arch Linux

Arch is a rolling distro, but did you ever wish it still had release numbers? So you could check what "version" you currently have installed, and upgrade to the latest "version" if necessary, with a reasonable delay between versions?
Of course you didn't. No sensible person would want to attach pseudo-version numbers to a rolling distro.
https://code.google.com/p/crover/
https://aur.archlinux.org/packages/crover/
crover returns a version number for Arch Linux based on time elapsed since the distro's initial release (March 11, 2002). The number format is X.Y, with X being years and Y being subdivisions of the current year. By default, the version number is generated for the current date with a subdivision size of one week.
As of this writing, the current version is Arch Linux 12.1. In other words, Arch is 12 years and 1 week old.

Hmm, you could actually make this somewhat more relevant to actual update practices if you wanted. Were I to try to accomplish such a task, I would figure out a way to check and see if all the official repos are up-to-date (or just if all the packages the user has installed are up-to-date with `checkupdates`). Then, take the number of seconds elapsed since Arch's release till the last update (which brought that rig up-to-date).
Then, you could grab the user's list of currently installed packages with pacman and take a hash of it. And, by concatenating those two figures together, you could get some semblance of a "version" number. For example, mine would be something similar to the following:
378691200.4c41d609
Not to mention, with this calculation, it would not be difficult to format the time part of the version in a variety of ways. May be worth thinking about
All the best,

  • Backpac: A package state snapshot and restore tool for Arch Linux

    backpac:
    A package state snapshot and restore tool for Arch Linux with config file save/restore support.
    https://aur.archlinux.org/packages.php?ID=52957
    https://github.com/altercation/backpac (see readme on the github repository for more information)
    Summary & Features
    It's a common method of setting up a single system: take some notes about what packages you've installed, what files you've modified.
    Backpac creates those notes for you and helps back up important configuration files. Specifically, backpac does the following:
    maintains a list of installed groups (based on 80% of group packages being installed)
    maintains a list of packages (including official and aur packages, listed separately)
    maintains a list of files (manually created)
    backs up key config files as detailed in the files list you create
    The package, group and files lists along with the snapshot config files allows system state to be easily committed to version control such as git.
    Backpac can also use these lists to install packages and files. Essentially, then, backpac takes a snapshot of your system and can recreate that state from the files and lists it archives.
    Use Cases
    Ongoing system state backup to github
    Quick install of new system from existing backpac config
    Conform current system to given state in backpac config
    Backpac is a very, very lightweight way of saving and restoring system state.
    It's not intended for rolling out and maintaining multiple similar systems, it's designed to assist individual users in the maintainance of their own Arch Linux box.
    Status
    Alpha, release for testing among those interested. Passing all tests right now but will continue to rework and refine. Bug reports needed.
    Why?
    There are a lot of 'big-iron' solutions to maintaining, backing up and restoring system state. Setting these up for a single system or a handful of personal systems has always seemed like overkill.
    There are also some existing pacman list making utilities around, but most of them seem to list either all packages or don't separate the official and aur packages the way I wanted. Some detect group install state, some don't. I wanted all these features in backpac.
    Finally, whatever tool I use, I'd like it to be simple (c.f. the Arch Way). Lists that are produced should be human readable, human maintainable and not different from what I'm using in non-automated form. Backpac fulfills these requirements.
    Regarding files, I wanted to be able to backup arbitrary system files to a git repository. Tools like etckeeper are interesting but non /etc files in that case aren't backed up (without some link trickery) and there isn't any automatic integration with pacman, so there is no current advantage to using a tool like that. I also like making an explicit list of files to snapshot.
    Sample Output
    This is the command line report. Additionally, backpac saves this information to the backpac groups, packages and files lists and the files snapshot directory.
    $ backpac -Qf
    backpac
    (-b) Backups ON; Files will be saved in place with backup suffix.

    firecat53 wrote:I think your plan for handling an AUR_HELPER is good. If AUR_HELPER is defined by the user, then either you might need a list of major AUR helpers and their command line switches so you can pick the correct switch for what needs to be done (most use some variation of -S for installing, but not all), or have the user define the correct switch(es) somehow for their chosen AUR helper.
    That's a good idea. I'll add that to my AUR refactoring todo.
    I also found directory tracking to be a weakness in other dotfile managers that I tried. I think you would definitely have to recursively list out the contents of a tracked directory and deal with each file individually. Wildcard support would be nice...I just haven't personally found a use case for it yet.
    I've been thinking that I could just add the directory and scan through it for any non-default attribute files. If those are found then they get automatically added to the files list. That's pretty close to what etckeeper does.
    Edit: I just compiled the dev version and removed my comments for already fixed things...sorry!
    The master branch should have those fixes as well, but I didn't update the version number in the package build. I'll have to do that.
    1. Still apparently didn't handle the escaped space for this item: (the file does exist on my system)
    Ok, good to know. This wildcard directory business will require some new code and refactoring so I'll also rework my filenames handling.
    2. Suggestion: you should make that awesome README into a man page!
    I was working on one (the pkgbuild has a commented out line for the man page) but I had to leave it for later. Definitely want a man page. Once this stabilizes and I'm sure there aren't any big structural changes, I'll convert it to man format.
    3. Suggestion: add the word 'dotfile' into your description somewhere on this page, the github page, and in the package description so people looking for dotfile managers will find it. You could also consider modularizing the script into a dotfile manager and the package manager, so people on other distros could take advantage of your dotfile management scheme.
    I actually have a different script for dotfile management that doesn't touch packages, but there is definitely overlap with this one. That script isn't released yet, though, and if people find this useful for dotfile management that's great. I'll add that in.
    4. Suggestion: since -Q is a read-only operation, why not just make it run with -f automatically to avoid the prompt?
    Originally, running backpac without any command line options produced the Query output. I was concerned that since it is a utility that can potentially overwrite system files, it is important to give users a clear statement prior to execution about what will be done. Since the Query output is essentially the same as the Update and System reports in format and content, I wanted to be explicit about the Query being a passive no-change operation. The current command line options aren't set in stone though. If you feel strongly about it being different, let me know.
    Long answer to a short question
    5. Another suggestion: any thought to providing some sort of 'scrub' function to remove private information from the stored files if desired? This would be cool for publishing public dotfiles to github. Perhaps a credentials file (I did this with python for my own configs). Probably detecting email addresses and passwords without a scrub file would be rather difficult because dotfiles come in so many flavors.
    Yes, absolutely. In fact, if you look at the lib/local file (pretty sure it's in both master and dev branches in this state) you'll see some references to a sanitize function. The idea there is that the user will list out bash associative arrays like this:
    SANITIZE_WPA_=(
    [FILE]='/etc/wpa_supplicant.conf'
    [CMD]='sed s/expungepattern/sanitizedoutput/g'
    Question: am I missing an obvious option to remove a file from the files.d directory if I delete it from the files list? Or do I have to delete it manually? It might be helpful to add a section to the README on how to update and delete dotfiles from being tracked, and also a more detailed description of what the -b option does (and what is actually created when it's not used).
    You are only missing the function I didn't finish. There should be either dummy code or a TODO in the backpac main script referencing garbage collection, which isn't difficult but I just haven't finished it. The idea being another loop of "hey I found these old files in your files.d, mind if I delete them?" It's on my list and I'll try to get it in asap.
    And finally, just out of curiosity, why did you choose to actually copy the files instead of symlink like so many other dotfile managers do?
    git not following symlinks, hardlinks also out for permissions issues (git wouldn't be able to read the files, change them, etc.)
    I definitely would prefer to not make an entire copy of the file, but I haven't come up with a better option. Shout with ideas, though. Also, if there is a way around the link issues I noted above, let me know. I don't see one but that doesn't mean it's not there.
    edit: I think a Seattle area Arch meetup would be cool! Perhaps coffee someplace? Bellevue? U-district? Anyone else? BYOPOL (bring your own pimped out laptop)
    A general meetup sounds good. I was also thinking it would be fun to do a mini archcon with some demos.

  • Ubuntu look-alike gnome theme for arch linux

    Is there any theme/gnome package(s) for arch linux that will give me gnome that looks kind of like the gnome package for ubuntu? I'm moving over from ubuntu to arch, and I'm hoping to ease the transition at first while I get used to the rest of the system. Thanks!
    EDIT:  Actually, how configurable is xfce? I've used gnome and kde for arch a bit, but they're just so vanilla, and I'm still looking for a relatively nice graphical interface on top of cli. Thanks!
    Last edited by pythonscript (2009-07-27 23:29:40)

    xfce4 is just about as configurable as GNOME at the level of gconf/ xfconf and way more configurable via the settings GUI.

  • Localepurge for arch linux

    I just seeked for some thing to clean unused locales from my system and while I used gentoo I used localepurge, so I realize update this script for Arch linux
    # unpac this package to your /usr/local (it will make sbin/localepurge and share/localepurge/*)
    robertek.no-ip.org/files/localepurge/localepurge.tar.bz2
    #copy this file to /etc/locale.nopurge (or wherever else but than you must edit /usr/local/sbin/localepurge)
    robertek.no-ip.org/files/localepurge/locale.nopurge
    !!!! Before run edit locale.nopurge file and write there your locales you dont want to delete !!!!!
    Than if you are pretty sure that you edit correct locales just add "#" before NEEDSCONFIGFIRST
    than you can run localepurge (/usr/local/sbin/localepurge if you dont have /usr/local/sbin in your PATH)
    !!! BE CAREFULL THERE IS NO WARANTY FOR THIS SCRIPT AND DONT BLAME ME FOR CORRUPTING YOUR SYSTEM !!!! (anyone can just scroll the script and look if it is correct by you look)
    For me it work great an I just delete more than 100MB of mess.
    Feel free to make a package out of it I will be pleased (and please share).

  • .dotjs and .dotcss for Arch Linux Users

    Hi all,
    I've created a new Google Chrome extension to enable the functionalities of .dotjs and .dotcss extensions for Arch Linux users.
    Check it here; https://github.com/azer/.w3
    Contributions and ideas are welcome,

    Thanks for doing this, never heard of dotjs before, but I love the idea and definitely have some use cases for this.
    Of course as an arch user, Im just kindly asking if you plan to create an AUR - package for this?

  • Thanks for Arch Linux

    I am a huge fan of GNU/Linux and have been since the mid 90's, and I just want to say thank you for Arch Linux. My GNU/Linux history started with Red Hat, and then Slackware, then ultimately Gentoo Linux. I have been a Gentoo Linux fan for many years (since it's beginnings), and to be honest, Arch Linux is just as fast and in some cases faster than Gentoo Linux.
    The install for me as a first time user to Arch Linux, was very VERY simple, and straight forward. I love the idea of it being installed at the absolute minimum, and I having the option to chose which optional packages are and are not installed from the get-go.
    As stated, which this distrobution of GNU/Linux there is no need to compile from source, as Arch Linux is very fast already; for me and my computer anyway.
    Again, thanks for this great and powerful GNU/Linux distro.

  • Win32 loader for Arch Linux?

    Hi all,
    Do you know any project like the win32 loader of Debian/Ubuntu for Arch Linux is on-going?
    I am really interesting to install Arch Linux this way on my Windows laptop, than to use VMware or VirtualBox.

    Pajaro wrote:what is win32 loader?
    It is a program (.exe file) on Windows to let you install Debian(or Ubuntu) Linux inside Windows without modifying your disk partitions. Actually, the installed Linux image is a file on Windows filesystem, and you can boot into it via the boot menu of GRUB.

  • System encryption using LUKS and GPG encrypted keys for arch linux

    Update: As of 2012-03-28, arch changed from gnupg 1.4 to 2.x which uses pinentry for the password dialog. The "etwo" hook described here doesn't work with gnupg 2. Either use the openssl hook below or use a statically compiled version of gnupg 1.4.
    Update: As of 2012-12-19, the mkinitcpio is not called during boot, unless the "install" file for the hook contains "add_runscript". This resulted in an unbootable system for me. Also, the method name was changed from install () to build ().
    Update: 2013-01-13: Updated the hook files using the corrections by Deth.
    Note: This guide is a bit dated now, in particular the arch installation might be different now. But essentially, the approach stays the same. Please also take a look at the posts further down, specifically the alternative hooks that use openssl.
    I always wanted to set up a fully encrypted arch linux server that uses gpg encrypted keyfiles on an external usb stick and luks for root filesystem encryption. I already did it once in gentoo using this guide. For arch, I had to play alot with initcpio hooks and after one day of experimentation, I finally got it working. I wrote a little guide for myself which I'm going to share here for anyone that might be interested. There might be better or easier ways, like I said this is just how I did it. I hope it might help someone else. Constructive feedback is always welcome
    Intro
    Using arch linux mkinitcpio's encrypt hook, one can easily use encrypted root partitions with LUKS. It's also possible to use key files stored on an external drive, like an usb stick. However, if someone steals your usb stick, he can just copy the key and potentially access the system. I wanted to have a little extra security by additionally encrypting the key file with gpg using a symmetric cipher and a passphrase.
    Since the encrypt hook doesn't support this scenario, I created a modifed hook called “etwo” (silly name I know, it was the first thing that came to my mind). It will simply look if the key file has the extension .gpg and, if yes, use gpg to decrypt it, then pipe the result into cryptsetup.
    Conventions
    In this short guide, I use the following disk/partition names:
    /dev/sda: is the hard disk that will contain an encrypted swap (/dev/sda1), /var (/dev/sda2) and root (/dev/sda3) partition.
    /dev/sdb is the usb stick that will contain the gpg encrypted luks keys, the kernel and grub. It will have one partition /dev/sdb1 formatted with ext2.
    /dev/mapper/root, /dev/mapper/swap and /dev/mapper/var will be the encrypted devices.
    Credits
    Thanks to the authors of SECURITY_System_Encryption_DM-Crypt_with_LUKS (gentoo wiki), System Encryption with LUKS (arch wiki), mkinitcpio (arch wiki) and Early Userspace in Arch Linux (/dev/brain0 blog)!
    Guide
    1. Boot the arch live cd
    I had to use a newer testing version, because the 2010.05 cd came with a broken gpg. You can download one here: http://releng.archlinux.org/isos/. I chose the “core“ version. Go ahead and boot the live cd, but don't start the setup yet.
    2. Set keymap
    Use km to set your keymap. This is important for non-qwerty keyboards to avoid suprises with passphrases...
    3. Wipe your discs
    ATTENTION: this will DELETE everything on /dev/sda and /dev/sdb forever! Do not blame me for any lost data!
    Before encrypting the hard disc, it has to be completely wiped and overwritten with random data. I used shred for this. Others use badblocks or dd with /dev/urandom. Either way, this will take a long time, depending on the size of your disc. I also wiped my usb stick just to be sure.
    shred -v /dev/sda
    shred -v /dev/sdb
    4. Partitioning
    Fire up fdisk and create the following partitions:
    /dev/sda1, type linux swap.
    /dev/sda2: type linux
    /dev/sda3: type linux
    /dev/sdb1, type linux
    Of course you can choose a different layout, this is just how I did it. Keep in mind that only the root filesystem will be decrypted by the initcpio. The rest will be decypted during normal init boot using /etc/crypttab, the keys being somewhere on the root filesystem.
    5. Format  and mount the usb stick
    Create an ext2 filesystem on /dev/sdb1:
    mkfs.ext2 /dev/sdb1
    mkdir /root/usb
    mount /dev/sdb1 /root/usb
    cd /root/usb # this will be our working directory for now.
    Do not mount anything to /mnt, because the arch installer will use that directory later to mount the encrypted root filesystem.
    6. Configure the network (if not already done automatically)
    ifconfig eth0 192.168.0.2 netmask 255.255.255.0
    route add default gw 192.168.0.1
    echo "nameserver 192.168.0.1" >> /etc/resolv.conf
    (this is just an example, your mileage may vary)
    7. Install gnupg
    pacman -Sy
    pacman -S gnupg
    Verify that gnupg works by launching gpg.
    8. Create the keys
    Just to be sure, make sure swap is off:
    cat /proc/swaps
    should return no entries.
    Create gpg encrypted keys (remember, we're still in our working dir /root/usb):
    dd if=/dev/urandom bs=512 count=4 | gpg -v --cipher-algo aes256 --digest-algo sha512 -c -a > root.gpg
    dd if=/dev/urandom bs=512 count=4 | gpg -v --cipher-algo aes256 --digest-algo sha512 -c -a > var.gpg
    Choose a strong password!!
    Don't do this in two steps, e.g don't do dd to a file and then gpg on that file. The key should never be stored in plain text on an unencrypted device, except if that device is wiped on system restart (ramfs)!
    Note that the default cipher for gpg is cast5, I just chose to use a different one.
    9. Create the encrypted devices with cryptsetup
    Create encrypted swap:
    cryptsetup -c aes-cbc-essiv:sha256 -s 256 -h whirlpool -d /dev/urandom create swap /dev/sda1
    You should see /dev/mapper/swap now. Don't format nor turn it on for now. This will be done by the arch installer.
    Important: From the Cryptsetup 1.1.2 Release notes:
    Cryptsetup can accept passphrase on stdin (standard input). Handling of new line (\n) character is defined by input specification:
        if keyfile is specified as "-" (using --key-file=- or by positional argument in luksFormat and luksAddKey, like cat file | cryptsetup --key-file=- <action> ), input is processed
          as normal binary file and no new line is interpreted.
        if there is no key file specification (with default input from stdin pipe like echo passphrase | cryptsetup <action> ) input is processed as input from terminal, reading will
          stop after new line is detected.
    If I understand this correctly, since the randomly generated key can contain a newline early on, piping the key into cryptsetup without specifying --key-file=- could result in a big part of the key to be ignored by cryptsetup. Example: if the random key was "foo\nandsomemorebaratheendofthekey", piping it directly into cryptsetup without --key-file=- would result in cryptsetup using only "foo" as key which would have big security implications. We should therefor ALWAYS pipe the key into cryptsetup using --key-file=- which ignores newlines.
    gpg -q -d root.gpg 2>/dev/null | cryptsetup -v -–key-file=- -c aes-cbc-essiv:sha256 -s 256 -h whirlpool luksFormat /dev/sda3
    gpg -q -d var.gpg 2>/dev/null | cryptsetup -v –-key-file=- -c aes-cbc-essiv:sha256 -s 256 -h whirlpool -v luksFormat /dev/sda2
    Check for any errors.
    10. Open the luks devices
    gpg -d root.gpg 2>/dev/null | cryptsetup -v –-key-file=- luksOpen /dev/sda3 root
    gpg -d var.gpg 2>/dev/null | cryptsetup -v –-key-file=- luksOpen /dev/sda2 var
    If you see /dev/mapper/root and /dev/mapper/var now, everything is ok.
    11. Start the installer /arch/setup
    Follow steps 1 to 3.
    At step 4 (Prepare hard drive(s), select “3 – Manually Configure block devices, filesystems and mountpoints. Choose /dev/sdb1 (the usb stick) as /boot, /dev/mapper/swap for swap, /dev/mapper/root for / and /dev/mapper/var for /var.
    Format all drives (choose “yes” when asked “do you want to have this filesystem (re)created”) EXCEPT for /dev/sdb1, choose “no”. Choose the correct filesystem for /dev/sdb1, ext2 in my case. Use swap for /dev/mapper/swap. For the rest, I chose ext4.
    Select DONE to start formatting.
    At step 5 (Select packages), select grub as boot loader. Select the base group. Add mkinitcpio.
    Start step 6 (Install packages).
    Go to step 7 (Configure System).
    By sure to set the correct KEYMAP, LOCALE and TIMEZONE in /etc/rc.conf.
    Edit /etc/fstab:
    /dev/mapper/root / ext4 defaults 0 1
    /dev/mapper/swap swap swap defaults 0 0
    /dev/mapper/var /var ext4 defaults 0 1
    # /dev/sdb1 /boot ext2 defaults 0 1
    Configure the rest normally. When you're done, setup will launch mkinitcpio. We'll manually launch this again later.
    Go to step 8 (install boot loader).
    Be sure to change the kernel line in menu.lst:
    kernel /vmlinuz26 root=/dev/mapper/root cryptdevice=/dev/sda3:root cryptkey=/dev/sdb1:ext2:/root.gpg
    Don't forget the :root suffix in cryptdevice!
    Also, my root line was set to (hd1,0). Had to change that to
    root (hd0,0)
    Install grub to /dev/sdb (the usb stick).
    Now, we can exit the installer.
    12. Install mkinitcpio with the etwo hook.
    Create /mnt/lib/initcpio/hooks/etwo:
    #!/usr/bin/ash
    run_hook() {
    /sbin/modprobe -a -q dm-crypt >/dev/null 2>&1
    if [ -e "/sys/class/misc/device-mapper" ]; then
    if [ ! -e "/dev/mapper/control" ]; then
    /bin/mknod "/dev/mapper/control" c $(cat /sys/class/misc/device-mapper/dev | sed 's|:| |')
    fi
    [ "${quiet}" = "y" ] && CSQUIET=">/dev/null"
    # Get keyfile if specified
    ckeyfile="/crypto_keyfile"
    usegpg="n"
    if [ "x${cryptkey}" != "x" ]; then

    This hook allows for an encrypted root device with support for gpg encrypted key files.
    To use gpg, the key file must have the extension .gpg and you have to install gpg and add /usr/bin/gpg
    to your BINARIES var in /etc/mkinitcpio.conf.
    HELPEOF
    Edit /mnt/etc/mkinitcpio.conf (only relevant sections displayed):
    MODULES=”ext2 ext4” # not sure if this is really nessecary.
    BINARIES=”/usr/bin/gpg” # this could probably be done in install/etwo...
    HOOKS=”base udev usbinput keymap autodetect pata scsi sata usb etwo filesystems” # (usbinput is only needed if you have an usb keyboard)
    Copy the initcpio stuff over to the live cd:
    cp /mnt/lib/initcpio/hooks/etwo /lib/initcpio/hooks/
    cp /mnt/lib/initcpio/install/etwo /lib/initcpio/install/
    cp /mnt/etc/mkinitcpio.conf /etc/
    Verify your LOCALE, KEYMAP and TIMEZONE in /etc/rc.conf!
    Now reinstall the initcpio:
    mkinitcpio -g /mnt/boot/kernel26.img
    Make sure there were no errors and that all hooks were included.
    13. Decrypt the "var" key to the encrypted root
    mkdir /mnt/keys
    chmod 500 /mnt/keys
    gpg –output /mnt/keys/var -d /mnt/boot/var.gpg
    chmod 400 /mnt/keys/var
    14. Setup crypttab
    Edit /mnt/etc/crypttab:
    swap /dev/sda1 SWAP -c aes-cbc-essiv:sha256 -s 256 -h whirlpool
    var /dev/sda2 /keys/var
    15. Reboot
    We're done, you may reboot. Make sure you select the usb stick as the boot device in your bios and hope for the best. . If it didn't work, play with grub's settings or boot from the live cd, mount your encrypted devices and check all settings. You might also have less trouble by using uuid's instead of device names.  I chose device names to keep things as simple as possible, even though it's not the optimal way to do it.
    Make backups of your data and your usb stick and do not forget your password(s)! Or you can say goodbye to your data forever...

    I'm trying to run my install script that is based on https://bbs.archlinux.org/viewtopic.php?id=129885
    Decrypting the gpg key after grub works, but then "Devce root already exists." appears every second.
    any idea ?

  • Wocka 0.5 - checkinstall for Arch Linux

    Last updated: 17th-Feb-2007
    With Wocka you can do:
    ./configure
    make
    su
    wocka
    and you'll get the application installed, and a pacman db entry too.
    Wocka automatically figures out the package name, version and/or subversion revision, and if it can, other metadata too. It determines the build system (make, unsermake, scons, cmake, etc.). It can also create a basic PKGBUILD, with some of the fields (eg name, version) magically filled in. It can also handle upgrades and check AUR for PKGBUILDs.
    Visit the site for a Arch linux package, the source tarball, and detailed usage examples. There's also a feed you can subscribe to at the site if you want to be notified of updates.
    http://methylblue.com/wocka/
    Comments, contributions, etc. most welcome! Thanks.
    ===========
    I have discovered other programs that do a similar thing for Arch. They may be better and you may want to consider them, or at least demand I implement things they do into Wocka If you do use one of the others, I'd like to hear why, if you have the time, thanks!

    Firstly, I'm really sorry I didn't see the above new replies, I subscribed to this thread, but never got the emails... Must have been my spam filter I expect.
    Gullible Jones wrote:Wait a minute, why the heck does this thing require QT? It doesn't have a GUI so why would it use the QT library? :?
    I used Qt as I have 4 years experience with it and develop fast with it. With Qt4 the library is separated into Core (CLI only) and GUI components, so as soon as Arch ships Qt4 and people have it installed en-mass, I'll switch to the CLI only library. I apologise if you think I'm crazy/stupid, you may be right
    You should have talked to Xentac. He already has an app named "Wakka" IIRC.
    Hmm sucks, I may have to rename again. I renamed the first time as pacgen is a name already used by two other projects!

    heh could be, I'm not a pacman expert. Extralife the webcomic always makes pacman say "Wocka!", but I spose I should have done more research!
    phrakture wrote:Send a PKGBUILD to AUR!
    Yeah I half did this and then couldn't figure out how to work the AUR or something. I'll try again.
    I had 0.3 ready a few weeks ago, then I started using my CRT with my new XBOX 360 and didn't boot to Linux until yesterday Now I have some new TFTs.
    The changes since 0.2:
    · Automatic upgrade/merge for new installs of subversion managed source installations
    · Better versioning detection
    · Easy automatic AUR builds via: wocka --aur appname
    · Metadata is extracted from LSM files
    · --upgrade switch
    The upgrade switch basically merges the old package with what's just installed, so you don't lose any information, I figured this was the safest route. Please correct me if you disagree. Thanks

  • Mondo rescue and mindi patched for Arch Linux

    Mondo rescue is a disaster recovery tool.
    Last year, I wanted to test mondo rescue for the first time, but I found there was no official package and no PKGBUILD  in AUR.
    So I had to build one and upload it to AUR. But soon I found there were a lot of problems related to the lack of compatibility with Arch Linux.
    I had to deep in the code and made some patches that turned it usable in Arch system.
    Mondo version 2.2.9.5-2, and mindi-2.0.7.6-3 are now full compatible with Arch (at least for me).
    That's why I'm asking Arch users (if someone interested) to test mondo and mindi PKGBUILD's and give your feedback to help me to improve it.
    mondo AUR - http://aur.archlinux.org/packages.php?ID=38366
    mindi AUR - http://aur.archlinux.org/packages.php?ID=38365
    mindi-busybox - http://aur.archlinux.org/packages.php?ID=38364
    mondorescue website - http://www.mondorescue.org/
    Thank's for your feedback.

    You are right! The server is down :-(
    This server was an alternative I found for the original one that was also down at that time.
    Now http://www.hello-penguin.com/software.htm is up again, but I had some problems downloading source code with pacman.
    This is a little frustrating when servers are up and down intermittently.
    So, I made a mirror in my own server where buffer-1.19.tar.gz can be downloaded too, and uploaded a new version PKBUILD to AUR (http://aur.archlinux.org/packages.php?ID=38363).
    PKGBUILD now downloads source code from this alternative server, but if you wish, you can edit PKGBUILD and chose the original one (in the commented line).
    Hope this can be solved now.

  • Online Radio Management Software for Arch Linux

    After switching to Arch Linux, I found out that I have no interest to try any other distro. Unfortunately I really missed something that I have used in Ubuntu, and that was Sourcefabric : Airtime. It is a free opensource radio automation software, and that mean if you want to have an online radio, you can make it yourself using Airtime.
    Can somebody port this software to Arch Linux, or anybody have a better choice/solution? Any suggestion will greatly be appreciated. Thank you very much for spending your time reading this.

    Read about the AUR. Create a PKGFILE for it and then you can install it via makepkg. Then, if it works well, submit your PKGFILE to the AUR.

  • Virtual-Audio-Cable for Arch linux

    Hello guys,
    I'm quiet new to Arch-Linux and I love Arch-Linux (even if I sometimes hate it ).
    I wont to have and virtual audio-device where I can put some Out-Put of any program (for examble VLC) to an input device like a Microphone used by any application for example Teamspeak.
    In Windows I have the program Virtual-Audio-Cable for this and I already read that pulse-audio should serve this functionality, but when I install pulse-audio I don't get this sound-redirecting to work and I get Bugs like my music is stopping when I start Teamspeak or any application with sound output.
    So I wan't to have it (if possible) without using pulseaudio (I already removed it from my system).
    I'm thankful for any hints.
    Sincerely Basti

    pulseaudio comes with the module module-virtual-source. You can load it with pacmd and then use it like a virtual audio cable in pavucontrol.
    pacmd load-module module-virtual-source source_name=loop_source uplink_sink=loop_sink
    Then send sound to loop_sink and record from loop_source.
    Edit: If you want to listen and record at the same time, then you should be able to use module-virtual-sink I think and record from the monitor channel for the virtual sink.
    http://pulseaudio-discuss.freedesktop.n … ce-modules
    With pure alsa it should be possible with the aloop driver.
    Otherwise you'll have to learn JACK.

  • Complete theme for Arch Linux

    Hi guys. In celebration of Arch's new design, I finally decided to learn more about making wallpapers and GTK+ themes. Unfortunately, I had to basically hack an existing GTK+ theme (Smooth-Line), but it still looks good and matches the overall feel of Arch Linux, in my opinion.
    I've created a collection of files that themes the following things:
    GTK widgets
    Fluxbox
    desktop background
    urxvt
    The goal was to integrate seamlessly with the website's look and feel. I think I've succeeded:
    Unfortunately, I don't have an xcf of the background, so I doubt it can be scaled easily. I guess it's one of those things you don't think about when a project starts out being 'just for me'.
    I've uploaded a g-zipped tarball of the files you'll need to use the theme.
    http://sporkbox.us/linux/arch-theme.tar.gz
    * The sample .Xdefaults file allows you to change the colors for urxvt. Feel free to delete all the stuff before the "color#" lines.
    * gtkrc goes wherever you want it, but should be put in /usr/share/themes/Smooth-Arch/gtk-2.0/ if you want theme switching apps to recognize it.
    * The background can be put anywhere.
    * Arch-Linux goes in /usr/share/fluxbox/styles or ~/.fluxbox/styles.
    I hope you guys like it.
    EDIT: Updated the screenshot and fixed the link to the archive.

    Beat me to it.
    I've got loads of half-finished themes here (or did have; they might have gone when I switched to Arch) - once I found QtCurve, it just seemed too much hassle. It's not totally configurable from the GUI, but it certainly beats poring over gtkrcs until your eyes hurt.
    Edit: I meant to add that the wallpaper works quite well cropped to 5:4 if you take the right end. The big Arch logo loses its bottom left point, but it's not too bad.
