We run a search for case-insensitive matches for the word "quake." |
|||
Because we don't know how many matches the search will find, the |
|||
descriptions of all packages found are supressed with "--no." Note: "-n" |
|||
pertains to the not-installed (uninstalled) distribution. |

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. |

Oh no, xqf is going to be removed! Let's make sure that this isn't a |

package we want removed, but since we noticed a newer version of this |

package is included in the unstable distribution, let's find out what's |

going on here! |

XQF allows one to browse and choose quake servers to play on. |
|||
Reading Package Lists... |
|||
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? |
|||
|
|||
And all this is GPL'ed, of course. See the file COPYING for license details. |

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 |
|||

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. |

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 need a header file called w32skrnl.h. We are in luck it's already on our system. Notes: |

We could have done "locate w32skrnl.h" and then done a "swim -qf", but we haven't updated our |

locatedb in months. The package installation will be tested by apt if it exists. |

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. |
