pacman

pacman is a text based (although a “read-only” web gui exists) distribution configuration system that works out what software needs to go on what box. It takes much of the hard work out of daily distribution management. Pacman takes a set of configuration files as input and based on the rules produces a consistent list of packages for each target machine. This list is then used by subsequent programs to distribute the packages to those machines.

pacman is designed (in principle) to work with any unix based package and distrubtion system. In practice it has been configured for my own “kpackages” and distribution using CMU sup or my own pup. A trial Debian “apt-get” server front end has also been built.

The mostly-complete pacman user guide is attached. If you're interested in the product drop me an email: kim @ domain_name

pacman user guide

To set the context - pacman exceeds the abilities of other open source and commercial products we tested including expensive products from Sun (for example).

  • + : A leading plus sign indicates that this word must be present in every object returned.
  • - : A leading minus sign indicates that this word must not be present in any row returned.
  • By default (when neither plus nor minus is specified) the word is optional, but the object that contain it will be rated higher.
  • < > : These two operators are used to change a word's contribution to the relevance value that is assigned to a row.
  • ( ) : Parentheses are used to group words into subexpressions.
  • ~ : A leading tilde acts as a negation operator, causing the word's contribution to the object relevance to be negative. It's useful for marking noise words. An object that contains such a word will be rated lower than others, but will not be excluded altogether, as it would be with the - operator.
  • * : An asterisk is the truncation operator. Unlike the other operators, it should be appended to the word, not prepended.
  • " : The phrase, that is enclosed in double quotes ", matches only objects that contain this phrase literally, as it was typed.
