Slapt-get

slapt-get is an APT-like system for Slackware package management.

It tries to emulate the features of Debian's apt-get as closely as possible.

Features

uses native Slackware tools (installpkg, upgradepkg, and removepkg)
supports multiple package sources (including http://linuxpackages.net)
cache data concerning packages and updates from package sources
supports sources from ftp, ftps, http, https, file:/// and more (libcurl)
resumes broken downloads and will verify package integrity with MD5 checksum
show packages that are available (from cached data) and installed
search package listing using POSIX and extended regular expressions by package name, location, and description
retrieve, install, and remove packages by name or by specific version
retrieve and apply updates
upgrade from one Slackware release to another in a few simple steps - see Upgrade_Using_Slapt-get
show description of packages, including mirror location, version, size, dependencies (where available, see FAQ), conflicts (where available, see FAQ), suggestions (where available, see FAQ), description, and installation status
exclude (hold) packages from upgrades, by name or by regular expression
transaction engine for install, remove, and upgrades, reporting concise information on what is to be done, ensuring each step happens correctly
"compare package version" algorithm to prevent downgrades
recursive dependency resolution using slack-required meta-data (see FAQ) supporting hard, soft, and conditional dependencies
package conflict resolution using slack-conflicts meta-data (see FAQ)
package suggestion support for complimentary packages (see FAQ)
Package data download robustness, only writing changes if all sources download successfully as well as only downloading those sources that have changed since the last download
i18n support via GNU gettext with over 20 language translations
extremely fast and easy to script with

Dependencies

slapt-get does not provide dependency resolution for packages included within the Slackware distribution. It does, however, provide a framework for dependency resolution in Slackware compatible packages similar in fashion to the hand-tuned method Advanced Packaging Tool|APT utilizes. Several package sources and Slackware based distributions take advantage of this functionality.

Adding dependency information requires no modification to the packages themselves. Rather, the package listing file, PACKAGES.TXT, is used to specify these relationships. This file is provided by Patrick Volkerding and is similar to the Packages.gz file in use by Debian. Several scripts are available to generate the PACKAGES.TXT file from a group of packages (See FAQ #17). The file format used by Patrick Volkerding is extended by adding a few extra lines per package. slapt-get then parses this file during source downloads. Typically, third party packages store the dependency information within the package itself for later extraction into the PACKAGES.TXT (See FAQ #19). The inclusion of this information within the Slackware package format does not inhibit the ability for Slackware pkgtools to install these packages. This information is silently ignored and discarded after the package is installed.

Other methods exist for adding dependency information for official Slackware packages without altering the packages themselves.

Package Sources

slapt-get works with official Slackware mirrors and third party package repositories. slapt-get looks for support files, PACKAGES.TXT and CHECKSUMS.md5, in the repository for package information. These files provide package names, versions, sizes (both compressed and uncompressed), checksums, as well as a package description. These files can be extended, as discussed in the previous section, to add dependency listings, conflict information, and package suggestions. These files can also proxy for other remote sources by specifying a MIRROR declaration for each package.

libslapt

slapt-get exports a C library that is used by gslapt to provide similar functionality through a GTK+ frontend.
