tupac (turbo pacman) is a pacman database search engine that boosts pacman searches. The speed advantage is achieved by caching the pacman database.

Tasks like checking the integrity of an entire pacman-tracked installation, or finding orphans in large directories (like /usr), are performed in a few seconds.

tupac is not a pacman wrapper. Its coding is only related to pacman searches. For any other tasks it bypasses to yaourt.

Key features

  • Searches the AUR
  • It allows you to refine searches by utilizing AND searches rather than OR searches (looks for packages that match all words)
  • Automatic cache updates (no user intervention required at all).
  • Very fast file level operations (find owners, find missing files, etc)

Command Line Arguments

tupac: A cached pacman implementatioin. Version: 0.3.5

 Usage:
  tupac [word] [word] [word] ...     : Search for and install packages that match all [word]

  tupac -Qo [file] [file] [file] ... : Search for each [file] owner
  tupac --checkdir [directory]       : Check integrity of a directory.
  tupac --orphans [directory]        : Find files that are not part of any package
  tupac                              : Manual call to update cache
  tupac [anything else]              : bypass to yaourt
  tupac --set-proxy [host:port|none] : set up a proxy

  --safe                             : Only search for safe packages
  --noaur                            : Don't search in AUR

  --color [darkbg|lightbg|nocolor]   : Choose color scheme
  --repos repo1,repo2,repo3,...      : Set active repositories


What you must know

Tupac does not parse "/etc/pacman.conf". It works exclusively with the information available from the pacman database (/var/lib/pacman), so if you erase a repo from pacman.conf it will still be shown in tupac, unless you erase its directory from the database.

Installation

tupac is available from the AUR.

Design

Tupac is written in php because:

  • the serialize function makes caching a blink
  • much simpler/cleaner coding than bash. This allows the design and implementation to concentrate on speed optimization.

History

The initial idea was to boost some yaourt operations. tupac was intended to be a rewrite of pajman, a program written in bash that had the same objective- speed up pacman searches. When I got into the php context, (a programming language that I use frequently) the idea of creating a cache rapidly came to me. After implementing the file operations (orphans, owners, integrity checks), I got so impressed with the results that i decided to rename it to tupac, turbo pacman.
