# Alien::Package::Slp(3pm)

an object that represents a slp package

## NAME

Alien::Package::Slp - an object that represents a slp package

## DESCRIPTION

This is an object class that represents a slp package. It is derived from Alien::Package.

## CLASS DATA

The following data is global to the class, and is used to describe the slp package format, which this class processes directly.

- footer\_size

  Complete sizeof(slpformat) from slp.h in the stampede package manager source.

- footer\_packstring

  This is the pack format string for the footer. (A=space terminated character, I=unsigned integer.)

- footer\_version

  What package format are we up to now? (Lowest one this is still compatible with.)

- archtrans

  This is a translation table between architectures and the number that represents them in a slp package.

- fieldlist

  This is a list of all the fields in the order they appear in the footer.

## FIELDS

- compresstype

  Holds the compression type used in the slp file.

- slpkgversion

  Holds the slp package format version of the slp file.

## METHODS

- checkfile

  Detect slp files by their extension.

- install

  Install a slp. Pass in the filename of the slp to install.

- getfooter

  Pulls the footer out of the slp file and returns it.

- scan

  Implement the scan method to read a slp file.

- unpack

  Unpack a slp file. They can be compressed in various ways, depending on what is in the compresstype field.

- build

  Build a slp.

- conffiles

  Set/get conffiles.

  When the conffiles are set, the format used by slp (a colon-delimited list) is turned into the real list that is used internally. The list is changed back into slp's internal format when it is retrieved.

- copyright

  Set/get copyright.

  When the copyright is set, the number used by slp is changed into a textual description. This is changed back into a number when the value is retrieved.

- arch

  Set/get arch.

  When the arch is set, the number used by slp is changed into a textual description. This is changed back into a number when the value is retrieved.

- release

  Set/get release version.

  When the release version is retrieved, it is converted to an unsigned integer, as is required by the slp package format.
