Because we don't know how many matches the search will find, the

After looking at the descriptions for the packages found through the "quake" search we decide
|
||
|
|
to narrow down the search to "tools." Notes: We could have done this for any part of the
|
||
|
|
history by specifying a number. "--research" will not write the changes to the history,
|
||
|
|
"--refinesearch" will write the changes to the history. The qstat package is installed, but
|
||
|
|
there is a newer version.

Description: GTK program for manipulating pak archives
|
||
|
|
gtkpak is a nifty GTK tool for manipulating the pak archives used by Quake,
|
||
|
|
Quake 2, and QuakeWorld. It can view, extract, create, and append pak
|
||
|
|
archives. pak contains basic command-line utilities that can do much of
|
||
|
|
what gtkpak does without X or GTK, but gtkpak is easier to work with by
|
||
|
|
far. Installing both won't hurt anything.

Description: command-line tools for pak archives
|
||
|
|
This package contains pakx and pakc, a couple of tools for working with the
|
||
|
|
pak archives used by Quake, Quake 2, and QuakeWorld. pakc can create and
|
||
|
|
add files to archives, pakx can list and extract files from them. gtkpak
|
||
|
|
is a bit fancier but then again it requires X and GTK.

Building Dependency Tree...

Some packages could not be installed. This may mean that you have
|
||
|
|
requested an impossible situation or if you are using the unstable
|
||
|
|
distribution that some required packages have not yet been created
|
||
|
|
or been moved out of Incoming.
|
||
|
|
|
||
|
|
Since you only requested a single operation it is extremely likely that
|
||
|
|
the package is simply not installable and a bug report against
|
||
|
|
that package should be filed.
|
||
|
|
The following information may help to resolve the situation:
|
||
|
|
|
||
|
|
Sorry, but the following packages have unmet dependencies:
|
||
|
|
xqf: Conflicts: qstat (< 2.1z-2.1a-0.1) but 2.0b-1 is to be installed
|
||
|
|
E: Sorry, broken packages
|
||
|
|
linuxalive:/home/swim/SWIMANIA$ swim -qnT qstat
|
||
|
|
qstat_2.3e-1
|
||
|
|
Depends: libc6 (>= 2.1.2)
|
||
|
|
Conflicts: xqf (<< 0.9.2-1)
|
||
|
|
</pre>
|
||
|
|
|
||
|
|
<p> As seen above, the reason why xqf has to be removed is due to a
|
||
|
|
dependency in qstat which the packager (Michael Alan Dorman
|
||
|
|
<mdorman@debian.org>) will have to resolve by uploading a newer version of
|
||
|
|
xqf to the distribution. Sometimes necessary packages are still in
|
||
|
|
Debian's Incoming directory at the ftp site, and not in the distribution,
|
||
|
|
so we may want to check there first. If this isn't the case we will send
|
||
|
|
a bug report to Debian's Bug Tracking System pointing out that there needs
|
||
|
|
to be a newer version of xqf. In the meantime we have decided that we
|
||
|
|
only want gtkpak and pak. We will use swim's editing capabilities to take
|
||
|
|
gstat off the list. Notes: Another possibility for the bug shown above
|
||
|
|
is that apt's cache needs to be updated to reflect the changes in Debain's
|
||
|
|
distribution by using "swim --apt --update." When the history is edited
|
||
|
|
with "--stdin" the history makes a new entry reflecting the change. The
|
||
|
|
full history is accessible from "--stdin." Anybody can send a bug to
|
||
|
|
Debian's Bug Tracking System.

If we don't have apt we can still download these packages, and their sources. Here is another
|
||
|
|
way to do the same thing we did above without using apt. Notes: This time we saved some
|
||
|
|
typing by doing "--stdin" with "--research." We specified "--source" with "--ftp" to get the
|
||
|
|
sources as well as the packages, or we could have just gotten the sources by themselves by
|
||
|
|
specifying "--source_only" with "--ftp." Changes made while in "--stdin" are written to the
|
||
|
|
history.

We notice that the sources only had to be downloaded once. Looking at the packages'
|

|
|
information we notice both packages share the same sources as indicated in the "Source" field.
|
||
|
|
The field is absent for the pak package because the source name is exactly the same as the
|

|
|
package's name, but for the gtkpak package this isn't the case, so the "Source" field is
|
||

present.

0. Intro
|
||
|
|
|
||
|
|
gtkpak is a PAK file viewer for Gtk+. What are PAK files? A PAK file is used
|
||
|
|
in id software games such as Quake and Quake 2, and their spin-offs. Just
|
||
|
|
imagine collapsing an entire directory scheme into a big wad of files, and
|
||
|
|
there you have a PAK file.
|
||
|
|
|
||
|
|
The three binaries are built around the interface provided in pakfile.h,
|
||
|
|
which is a C++ class that allows access to the contents of a PAKFile, including
|
||
|
|
searching and extracting from an already existing PAK file, to add files and
|
||
|
|
then writing a new PAK file. The three binaries are then just front-ends
|
||
|
|
to this functionality, in one way or another.
|
||
|
|
|
||
|
|
While it's tempting to make the classes provided in pakfile.h into a shared
|
||
|
|
library, it's probably unnecessary. But it does make one tingly, eh?
|
||
|
|
|
||

We can check to see if the uninstalled distribution had any changes. Notes: The results below
|
||
|
|
indicate the changes found in the new Package databases that have been downloaded by updating
|
||
|
|
apt; if we don't have apt then swim's major mode "--ftp" can be used with "DF." With "--ndb"
|
||
|
|
use APT to indicate apt sources, or DF to indicate Package databases gotten directly through
|
||
|
|
swim's "--ftp". If we originally made the uninstalled distribution with an uninstalled
|
||
|
|
filesystem by using "--Contents DF" then to update the uninstalled distribution "--Contents
|
||
|
|
DF" should be used again; this isn't necessary when running a check. To rebuild
|
||
|
|
(--rebuildndb), update (--ndb), or check a distribution other than the default one, use
|
||
|
|
"--dists stable", "--dists frozen" or "--dists unstable." The newest Packages can
|
||
|
|
automatically be picked by using "--cron."
|
||
|
|
|
||
|
|
<p>
|
||
|
|
A little blurb: Although not Debian approved or sanctioned, we find the unstable distribution
|
||
|
|
acceptably stable in relation to certain well-known commercial distributions despite
|
||
|
|
infrequent packaging bugs like the one shown in the xqf example above. The Debian
|
||
|
|
distribution adheres to a self-imposed level of quality found in no other distribution in the
|
||
|
|
world. Usually, unstable undergoes many changes so there isn't a time advantage over updating
|
||
|
|
DF versus rebuilding DF, but this process is easier on system resources. On the other hand,
|
||
|
|
updating FDBDF (no uninstalled filesystem) is faster.

the changed packages except for the new ones which will be visible once we rebuild or update.

Description: A PostScript and PDF viewer for X using 3d Athena Widgets
|
||
|
|
`gv' is a comfortable viewer of PostScript and PDF files for the X
|
||
|
|
Window System.
|
||
|
|
.
|
||
|
|
It uses the `ghostscript' PostScript(tm) interpreter and is based
|
||
|
|
on the classic X front-end for `gs', `ghostview'. It is more
|
||
|
|
comfortable and more powerful than `ghostview'.
|
||
|
|
.
|
||
|
|
Some features as e.g. PDF files or anti-aliasing are only supported
|
||
|
|
if a recent ghostscript (4.0 or later) is installed. With
|
||
|
|
anti-aliasing turned on, the text is very crisp and readable, with no
|
||
|
|
`stepping' on the slants at all.

||
|

<p>

While we were in this directory we decided to do a little research. It is interesting to note
|
||
|
|
that for the installed system there are 14 files which don't belong to any packages. There
|
||
|
|
could be a variety of reasons for this (maybe we are slobs); this is good stuff to know.
|
||
|
|
Notes: To see the total list just add "-t" to the existing command-line options. There is a
|
||
|
|
big difference in using "." and "*", "." is the same as saying "./" but it only lists the
|
||
|
|
same package once, whereas "*" would look at all the files in the immediate directory and if
|
||
|
|
two files belong to the same package, that package will be shown twice for each file, it also
|
||
|
|
reports if a file doesn't belong to a package.

We happen to be hamradio enthusiasts. Let's see what packages exist in the hamradio group.

We edit the hamradio group package list with "--stdin." Notes: "--stdin" needs to be
|
||
|
|
called with either "--ftp", "-x", "-xyz", "-xz", "--purge", "-r", or "--remove" to work. This
|
||
|
|
is a readline interface. If we are in emacs mode (see man bash) here are some commands we can
|
||
|
|
use to make the process easier.

We are finding new ways to swim everyday; we often solve problems in minutes which used
|
||
|
|
to take an hour or more to solve. If you find a novel use for swim, please tell us, and we
|
||
|
|
will add it to these examples.
