slapt-get
open-in-new
<h2 id="features">Features</h2> <p>slapt-get builds functionality on top of the native <a href="/facts/Slackware/eGJIIHgW">Slackware</a> package tools (installpkg, upgradepkg and removepkg) enabling package query, remote fetching, system updates, integrated changelog information, and many optional advanced features<a class="footnote-ref" id="fnref:2" href="#fn:2"><sup>2</sup></a> such as dependency resolution, package conflicts, suggestions, checksum and public key verification, and transfer resumption. </p><p>slapt-get uses the libcurl <a href="/facts/CURL/01m2dW2j">cURL</a> library for transport. libcurl provides support for ftp, ftps, http, https, file:// and other resource types along with transfer resume for incomplete downloads. slapt-get also uses the <a href="/facts/GNU_Privacy_Guard/EqmGmx7V">GNU Privacy Guard</a> library to validate signatures. </p><p>slapt-get provides a simple configuration file format that includes an exclusion mechanism for use with the system upgrade option as well as declarations for all desired package sources. Each package source can optionally be tagged with a specific priority in order to override the package version comparison and honor upstream software downgrades as might be the case when Slackware reverts to a previous version of a package.<a class="footnote-ref" id="fnref:3" href="#fn:3"><sup>3</sup></a> </p> <h2 id="dependencies">Dependencies</h2> <p>slapt-get does not provide <a href="/facts/Coupling_(computer_science)/QEeSaXF3">dependency</a> resolution for packages included within the <a href="/facts/Slackware/eGJIIHgW">Slackware</a> distribution. It does, however, provide a framework for dependency resolution<a class="footnote-ref" id="fnref:4" href="#fn:4"><sup>4</sup></a> in <a href="/facts/Slackware/eGJIIHgW">Slackware</a> compatible packages similar in fashion to the hand-tuned method <a href="/facts/Advanced_Packaging_Tool/JQ3yu5G7">APT</a> utilizes.<a class="footnote-ref" id="fnref:5" href="#fn:5"><sup>5</sup></a> Several package sources and <a href="/facts/Slackware/eGJIIHgW">Slackware</a> based distributions take advantage of this functionality. Hard, soft, and conditional dependencies along with package conflicts and complementary package suggestions can be expressed using the slapt-get framework. </p><p>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 <a href="/facts/Patrick_Volkerding/fKI0n6aI">Patrick Volkerding</a> and is similar to the Packages.gz file in use by <a href="/facts/Debian/cBd93qfJ">Debian</a>. Several scripts are available to generate the PACKAGES.TXT file from a group of packages. The file format used by <a href="/facts/Patrick_Volkerding/fKI0n6aI">Patrick Volkerding</a> 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. The inclusion of this information within the <a href="/facts/Slackware/eGJIIHgW">Slackware</a> package format does not inhibit the ability for <a href="/facts/Slackware/eGJIIHgW">Slackware</a> pkgtools to install these packages. This information is silently ignored and discarded after the package is installed. </p> <h2 id="package-sources">Package sources</h2> <p>slapt-get works with official <a href="/facts/Slackware/eGJIIHgW">Slackware</a> mirrors and third party package repositories such as <a href="http://www.slacky.eu/">http://www.slacky.eu/</a>. 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. </p> <h2 id="gslapt">GSlapt</h2> <p>GSlapt is a <a href="/facts/GTK%2B/oLpVm9pp">GTK+</a> frontend to libslapt, the slapt-get library which provides advanced <a href="/facts/Package_management/kEX4kx7g">package management</a> for <a href="/facts/Slackware/eGJIIHgW">Slackware</a> and its derivatives. Inspired by the functionality present in <a href="/facts/Synaptic_(software)/3QdFfJxw">Synaptic</a>, Gslapt aims to bring the ease of use enjoyed by <a href="/facts/Debian/cBd93qfJ">Debian</a> and its derivatives to the <a href="/facts/Slackware/eGJIIHgW">Slackware</a> world. </p><p>GSlapt was written primarily to supersede the vlapt (x)dialog slapt-get frontend used by <a href="/facts/VectorLinux/06VKAcMe">VectorLinux</a>.<a class="footnote-ref" id="fnref:6" href="#fn:6"><sup>6</sup></a> </p> <h2 id="distributions">Distributions</h2> <p>Besides <a href="/facts/Slackware/eGJIIHgW">Slackware</a>, slapt-get and GSlapt are included by several other distributions, including: </p> <ul><li><a href="http://www.absolutelinux.org/">Absolute Linux</a></li> <li><a href="/facts/Salix_OS/jISV77eU">Salix OS</a></li> <li>Slamd64</li> <li><a href="/facts/VectorLinux/06VKAcMe">VectorLinux</a></li> <li>Wolvix</li></ul> <h2 id="external-links">External links</h2> <ul> <li>Free and open-source software portal</li></ul> <ul><li><a href="http://software.jaos.org/#slapt-get">Official website</a> </li> <li><a href="http://www.slackwiki.com/Slapt-get">Slapt-get</a> on SlackWiki</li></ul> <h2 id="references">References</h2> <ol> <li id="fn:1"><p>"README". software.jaos.org.
