Group packages by origin in aptitude //at 00:06 //by abe

from the reasons-for-loving-debian dept.

I always wondered how others recognise non-Debian packages in the aptitude package tree. I also missed the additional priority level in the hierachy well-known from good old dselect.

For the last one, I quickly found out that you can set the priority as subsection — it’s straight forward after you’ve read the documentation: Just add ,priority at the end of the default grouping method for package views under “Options → UI Options” in the aptitude menu.

Getting the origin as given in the Release file of the repository a package originates from is a little bit more difficult. You need to use the pattern() group function with the appropriate search pattern: pattern(~O)

Since already the default default grouping method for package views doesn’t fit into the dialog, I nowadays just edit /etc/apt/apt.conf directly for changes on aptitude’s default grouping method for package views. It now looks like this on several of my machines:

Aptitude::UI {
  Default-Grouping "filter(missing),status,section(subdir,passthrough),pattern(~O),section(topdir),priority";
};

In aptitude this looks like this:

[...]
  --- text - Text processing utilities
  --\ utils - Various system utilities
    --- Debian
    --- Mowgli
    --- volatile.debian.org
  --\ web - Web browsers, servers, proxies, and other tools
    --- Debian
    --- Opera Software ASA
  --\ x11 - The X window system and related software
    --\ Debian
      --- contrib - Programs which depend on software not in Debian
      --\ main - The main Debian archive
        --- Priority optional
        --- Priority extra
      --- non-free - Programs which are not free software
    --- Mowgli
[...]

Unfortunately this doesn’t work with all non-Debian repositories since a few repository maintainer, e.g. those from Emdebian, arrogate to just keep “Debian” as their packages’ origin. This could be solved, if there’s a possibility to group by e.g. repository URL (host and/or path).

Another problem I haven’t solved yet is that grouping by origin does neither work with locally created nor virtual packages nor tasks — probably since all of them lack an origin. Those branches are just empty or don’t even show up anymore with this configuration. I probably have to dig a little bit more in the aptitude documentation to resolve this.

Another problem: many repositories, such as Christian Marillat's debian-multimedia repository, don't bother to properly segregate packages into main, contrib, and non-free.

pattern(~O, !~O => other) seems to solve the problem of virtual packages, etc not showing for me.

Hackergotchi of Axel Beckert

About...

This is the blog or weblog of Axel Stefan Beckert (aka abe or XTaran) who thought, he would never start blogging... (He also once thought, that there is no reason to switch to this new ugly Netscape thing because Mosaïc works fine. That was about 1996.) Well, times change...

He was born 1975 at Villingen-Schwenningen, made his Abitur at Schwäbisch Hall, studied Computer Science with minor Biology at University of Saarland at Saarbrücken (Germany) and now lives in Zürich (Switzerland), working at the Network Security Group (NSG) of the Central IT Services (Informatikdienste) at ETH Zurich.
