Cupt

What is it?

Cupt is a partial re-implementation of APT suite from scratch.

FAQ

Why?

  • to finally avoid some bugs in APT design;
  • to introduce some useful features;
  • to make an extensible and readable codebase;

The first announcement is here. Also, on debian-devel-announce.

What infrastructure does Cupt use?

It uses the same APT infrastructure, e.g. index files, deb cache archive files, configuration files. It understands some of widely used APT options.

What features has Cupt already?

  • full-case strict dependency problem resolver;
  • command-line and APT-like option name checker;
  • case-sensitive search;
  • pinning by source package name;
  • pinning by package groups using shell-like patterns;
  • configurable 'depends' and 'rdepends' subcommands;
  • support of LZMA-compressed indexes;
  • 'satisfy' subcommand;
  • synchronization by source versions;
  • 'shell' subcommand;
  • debdelta integration.

What important features Cupt doesn't have?

  • handling of cdrom:// URIs.

Can I use Cupt along with libapt-based package managers?

Yes, you can mix apt-get/apt-cache/aptitude/etc. with cupt without bad consequences.

How to feedback?

  • file bugs against 'cupt' package in Debian
  • join #cupt on irc.debian.org
  • mail me directly

Development

Repository

Cupt uses Git. URIs: browse, clone: git://github.com/jackyf/cupt.git.

Current/stable branch

The stable branch is 2.x (master in the Git repository). Implemented in C++0x, consists of a runtime library, download method plugins and a console front-end to them. This is the branch which will probably go to Debian Wheezy.

The HTML version of the latest tutorial may be found, apart from the binary packages, here.

Old stable branch

The 1.x branch was written in Perl. This is the branch which went to Debian Squeeze.
